Repairing Damage to Plaster Walls


By DoItYourself.com Staff
Plaster walls, especially those in older homes, usually have cracks due to the house "settling" in its foundation, or holes from where furniture or doors have struck the plaster and damaged it. Repairing plaster walls is a fairly straightforward process. While it should be done right before a paint job (as the location of the repair will be visible), you may choose to repair the damage and match the patch as best as you can to the existing wall surface.

Hairline Cracks in Plaster Walls

Hairline cracks in plaster walls cannot be patched until there is something for the patch to adhere to. In order to provide a good seat for the patch, the hairline crack should be widened a bit. For long hairline cracks, remove a bit of plaster at intervals along the crack to provide a better seat. Clean out any dust or loose plaster with a damp towel.

Fill the crack with plaster using your spackling knife. As you do so, be sure to get into the gouges that you have made along the crack and overlap the existing plaster. This will allow the patch to cling to the vertical surface of the wall, ensuring a secure patch.

Allow the patch to dry for 24 hours. If your patch seems to have receded into the crack, patch it again and allow to dry for another 24 hours. If you notice an uneven surface, sand the patch smooth to match the rest of the wall. Prime and paint if necessary.

Repairing Holes in Plaster Walls

Clear away any dust or loose plaster around the hole that will prevent the patch from adhering to the wall. Carefully carve under the edge of the broken plaster, in order to provide a good seat for the plaster patch. In other words, try to make enough space for the plaster patch to slightly ooze underneath the existing layer of plaster. It's possible to do this with a curved metal tool, such as a can opener, as long as you can get underneath the existing plaster without unnecessarily breaking out more.

Dampen the edge of the hole and fill with patching plaster using a spackling tool. Make sure the patching plaster does not fill the hole level with the existing wall. It should fill the hole to a level just below the surface of the existing plaster - you want to leave enough space for the joint compound to cover the plaster patch and still be even with the wall's surface. Score the surface of the plaster patch with your spackling tool with vertical and horizontal lines, then allow to dry for 24 hours.

The next day, apply joint compound to the surface of the patch, spreading it just over the edges of the wall. When this has dried, apply another coat of joint compound, if necessary, to make the patch even with the existing wall. Sand even with the wall, and prime and paint if desired.

Repairing Outside Corners of Plaster Walls

Measure the vertical length of the damaged area. Use a length of wood that exceeds this vertical dimension, and tack it gently to the wall - flush with one of the corners - making sure that the length of the wood extends past the hole on both the top and the bottom. This will be your guide when you patch the outside corner so that you can get an edge that blends in with the undamaged portion of the corner. In other words, this piece of wood will act as an extension of the wall, giving you a surface that is much like the one you would have if you were repairing plaster damage on a flat wall.

Remove loose plaster, and undercut the hole to provide a good seat for the plaster patch. Use a plaster trowel to smooth in patching plaster away from the wooden guide, overlapping the existing wall slightly. After one side has dried, you may switch the position of the wooden guide to the other side of the damaged corner and repeat the process.

Once the patch has dried completely, sand smooth. In addition, fill any holes used to tack up the piece of wood with joint compound.

At first, repairing plaster damage seems like a daunting task. But take your time to patch plaster properly, and you will get solid, long-lasting results.

Sustainable Lawncare Information and Solutions




Millions of dollars are spent each year designing, implementing, and maintaining urban landscapes. Unfortunately, long-term problems are caused when these processes are not carried out properly. Many of these problems can be avoided or reduced by utilizing sustainable landscape practices. A landscape developed with sustainable practices will improve the environment by conserving resources and reducing chemical applications. A sustainable landscape will also reduce labor inputs making it less expensive to implement and maintain.
The key to creating a sustainable landscape is understanding that the design process should be considered first. Plant selection, implementation, and maintenance build on the design process, each having sustainability as a major consideration.

According to one estimate, 40 million acres of land is devoted to turfgrass in the United States with nearly 75 percent in home lawns and more than 30 billion dollars spent on annual lawn maintenance1. It is no wonder that the large amount of resources allocated to lawn care and the impact that they have on the environment has called the sustainability of lawns into question. This critical attention has challenged lawn managers and turfgrass research programs across the country to develop and work toward more sustainable, lower input turf/lawn ecosystems.

While SULIS defines sustainability in a general way, sustainability as it relates to lawns can be defined as a lawn area that requires few material inputs while having a positive impact on the environment. Creating and maintaining a more sustainable lawn begins with proper selection of the best adapted grass species and varieties. Proper site preparation, lawn installation, and appropriate follow-up care will help reduce the need for inputs of the established lawn.

The Sustainable Lawn Care Information Series (SLC) consists of the following chapters.
1Upper Midwest Home Lawn Care Calendar for Cool Season Grasses
The lawn care calendar is a guide for maintaining lawns in the upper midwest area. It covers the general care needed to maintain an average home lawn typically found in this geographic area. It is not intended to cover all aspects of lawn care, or to cover all different growing conditions that may exist on a specific property.
2Environmental Benefits of a Healthy, Sustainable Lawn
As a groundcover, healthy lawns provide important environmental benefits to our communities. Properly established and managed lawns, combined with good sustainable landscape design, can help protect and preserve water quality.
3Grass Plant Growth and its Relationship to a Sustainable Lawn
Understanding a few basic principles of grass plant biology is important. Planning maintenance to take advantage of the natural growth cycles and habits of grass is the first step in developing a more sustainable lawn care approach.
4Turfgrass Selection for a Sustainable Lawn
Lawn sustainability begins with good landscape design. Selecting the best adapted species and varieties for particular areas of the landscape is just as important as choosing trees and shrubs best adapted to the different locations within a landscape.
5Establishing a New Lawn to Achieve Sustainability
The best time to build in sustainability is when an area is first being prepared for a lawn. Following tried and true methods for site preparation and grass establishment will help insure a successful and sustainable lawn for many years to come.
6Renovating an Existing Lawn to Achieve Sustainability
Introducing lower input grasses into an existing lawn will often be the first step in establishing a more sustainable lawn cover. Also, using the elements of sustainable landscape design to evaluate appropriate locations for lawn areas will help create a more overall sustainable landscape.
7Understanding and Using Lawn Fertilizers
A vast array of fertilizers are available for use on lawns. Choosing those best suited to your site (such as near water bodies) or to the plant species and varieties in your lawn, does not need to be intimidating. A healthy lawn, achieved with modest inputs of the proper materials, can be very satisfying.
8Mowing Practices
How a lawn is mowed largely determines the need and frequency of maintenance required by that lawn. Sharp blades and proper height of cut will help keep grass growing vigorously and maintain adequate shoot density to completely cover the soil surface.
9Watering Practices
Efficient watering practices are important to all homeowners who want to conserve water, maintain a sustainable, healthy turf and reduce maintenance costs. Understanding how grass plants use water and their ability to tolerate dry conditions is the first step to putting the right plant in the right place to perform the right function. This is a key concept in establishing a more sustainable lawn.
10Weed Management
Too often, the term "sustainable lawn" has been associated with lawns allowed to become neighborhood weed patches with no resemblance to a "maintained" lawn. While lawns maintained on very low inputs may have a few weedy plants in them, having well-adapted grass species and varieties will help keep significant weed infestation to a minimum.
11Home Lawn Disease and Insect Pests
Properly maintained and healthy turfgrass will tolerate the presence of low levels of pest populations without suffering permanent damage. Healthy turfgrass usually recovers more quickly from insect and disease infestations. However, there may be times, even in healthy lawns, where some pest control is needed to prevent significant damage.

World Class Supply carries Pearl's Premium grass seed, which once established requires no watering, is ever-green, only needs to be mown once a month.  This translates to the saving of  time, equipment, gas and machine pollution from the usual 7-10 day grass mowing.

5 Ways You Can Lower Your Utility Bills This Summer




Excerpted from : thegoodhuman.com
May 01st, 2013

The easiest way to increase the amount of spare cash you have each month is by simply spending less. Now we can all cut down on our luxury items, or spend less on going for days out or meals with friends. But wouldn’t it be much better to cut down on the cost of your utility bills instead? Here are five ways you can lower your utility bills this summer.
1. Utilize Rain Barrels
Collecting rainwater from your roof and using it to water your garden will slash the amount of water consumption your household uses during the hot summer months. During the growing season, homeowners can save around 1,300 gallons of water, which adds up to a large amount on the water bill. Just half an inch of water is often enough to fill a 50-gallon rain barrel. If you install a few of these barrels, you may not need to turn the main tap on all year.
2. Plant Trees in Your Garden
Planting trees to the south and west of your house can lower energy consumption by around 5% in the summertime due to the shade it provided on the house. The bigger the trees the better, as they provide more shade for the house.
3. Use Solar Shades
If your home has lots of south-facing windows, the solar energy entering your home could be dramatically heating the property and costing you money to try and keep it cool again. Solar shades are a low-cost, effective way to reduce the amount of heat entering your home, and this will dramatically lower your electricity bill as you will not have to use fans or air conditioning nearly as much.
4. Keep it Clean
If you’re using an air conditioning unit, it’s essential that you carry out a monthly maintenance routine in order to keep the filters clean and the system working efficiently. A blocked filter can cost you money as the machine is not working as effectively as it could. Also, keeping your house clean tidy, and clutter free will increase the airflow around the property which also helps to lower the cost of cooling.
5. Alter Your Diet
During the summer months when you spend all day trying to keep the house cool, putting the oven on for hours at a time to cook your dinner or bake a cake is simply counter-productive. This can cause a huge temperature rise in your home and will cost more money to keep the temperature low during this time. Either cut down on your oven use and eat more salads and cool foods, or shut the kitchen door so that you are only heating one room.
Each of these simple steps may only make a small difference to the cost of your utility bills over the summer. If you make a lot of new habits over the coming months, trying to reduce energy consumption in lots of different ways, you will notice the reduction in your bills.

Green Home Prices Up, Study Say



A home in Eagle Rock, California featuring sustainable design. Photo: Flickr
News from Christina Caldwell  08/13/12 Earth911.com
Is a green-certified home worth the up-front cost? For many Californians, at least according to a new study, that answer is yes.
A new study by professors from the University of California Berkeley and UCLA shows that not only is demand for green homes still high in eco-minded areas, but certified green homes sell for around 9 percent more than less environmentally-savvy homes.
The study looked at 1.6 million homes sold in California from 2007 and early 2012. There seems to be a certain community attitude associated with green living dubbed the “Prius Effect,”according to the study’s authors, in which consumers that lived in areas where support for sustainability and hybrid ownership was high were willing to pay more for green certified homes.
Though, the willingness to pay more for green certification might be a trade off for the temperate climates of California. The study found that Californians living in warmer parts of the state like those in Central Valley were more willing to factor in capitalized cost savings than their northern and coastal counterparts.
Other studies that looked at green home purchases on a smaller level concluded that green certified homes in Seattle sell for an average of 8.5 percent more than their non-certified competition, based on a sample of homes sold between September 2007 and December 2009. In Portland, Oreg., that number rises to 12 percent, based on a study conducted from May 2008 to April 2009.
Higher prices aren’t just associated with homes. According to one UC Berkeley study, offices with green certifications rent for at least 3 percent higher and sell for 16 percent more than non-certified offices.

AIA/COTE Announces 2013 Top Ten Green Projects

Nadav Malin
This story first appeared on BuildingGreen.
April 23, 2013
355 11th Street: The Matarozzi/Pelsinger Multi-Use Building; Aidlin Darling Design; San Francisco, California
With an outstanding 2013 line-up, the American Institute of Architects’ Committee on the Environment (AIA/COTE) Top Ten Green Projects continues in its role as the nation’s premier showcase of projects that marry good design and green performance.
This year’s projects continue the strong focus from 2012 on social consciousness. “This group of projects underscored the social value of providing high functioning buildings for people who are often without the benefit of that,” notes juror Gail Vittori of the Center for Maximum Potential Building Systems. Working with limited budgets didn’t seem to hurt many of the winners. In fact, as juror Fiona Cousins of Arup points out, “In many cases, the slightly more financially constrained budgets actually produced better outcomes.”
There was a wide spread in terms of energy performance among the submissions. Juror Lance Hosey of RTKL laments that “only half the submissions conformed to current targets for the 2030 Commitment,” yet there were many, especially among the winners, that either achieved or came close to achieving net-zero energy. The energy strategies were generally well integrated but otherwise unsurprising, while “the water category was where the experimentation and innovation was happening,” says Vittori. A number of projects are driving code changes in their communities, blazing a trail for future projects by making nonpotable water sources more acceptable to health officials. But the biggest news is the first-ever Top Ten Plus awardee: 355 11th Street in San Francisco achieved the recognition as a past Top Ten winner (in 2010) and has proven itself through ongoing performance.
Top Ten Plus Winner: 355 11th Street, The Matarozzi/Pelsinger Multi-Use Building
Aidlin Darling Design
Since earning LEED Gold certification in 2009 and garnering a 2010 AIA Top Ten, this derelict historic building became home to a cherished restaurant that itself earned LEED for Commercial Interiors Platinum certification. The restaurant kitchen uses much more energy than the construction firm’s offices above, which are beating their modeled prediction despite a 40% increase in occupancy. The bicycle storage and changing rooms are put to good use, as 65% of the 81 employees in the building’s three business either bike or take public transportation.
A New Norris House
College of Architecture & Design, University of Tennessee–Knoxville
This tiny model home recaptures and updates many of the enduring features of the original model homes built 75 years ago in Norris, Tennessee—one of the first planned communities in the U.S. The 1,000-square-foot modular home brings to the established community a new ecological consciousness in the form of native plantings, water efficiency, energy efficiency, day lighting, and material choices, among other features. The interdisciplinary design-build curriculum that created the home was recognized in 2011 with the prestigious NCARB Prize for the Creative Integration of Practice and Education.
Charles David Keeling Apartments
KieranTimberlake
This project comprises three buildings wrapped around a courtyard that greatly enhance the student housing options at the University of California–San Diego. Overlooking the Pacific Ocean in a mild climate, the apartments are designed to take advantage of natural ventilation and views, with exterior walkways. A layered facade provides both fixed and operable shading to prevent overheating, helping avoid the need for air conditioning. Responding to the high value of water in this arid climate, the project is the first in the University of California campus system to harvest graywater, which is used to irrigate plantings on the vegetated roof and at grade level.
Clock Shadow Building
Continuum Architects + Planners
Providing a home for several healthcare-related nonprofit organizations in an underserved neighborhood of Milwaukee, the four-story Clock Shadow Building proves that a tight budget need not interfere with ambitious goals. To make use of the narrow brownfield site, the upper stories are cantilevered over a public right-of-way. The designers and builders collaborated throughout the process to use as many salvaged materials as possible by identifying and procuring some materials early on and by adjusting the design to accommodate others as they became available. The project embraces natural ventilation during temperate swing seasons, and a rooftop garden gives tenants a pleasant outdoor space. The garden and a cistern ensure that the project doesn’t contribute to combined sewer overflow events; this is the first project permitted in Milwaukee to use rainwater to flush toilets.
Federal Center South Building 1202
ZGF Architects


The 209,000-square-foot Building 1202 on Seattle’s Federal Center South Campus is a new regional headquarters for the U.S. Army Corps of Engineers Northwest District. A range of energy-efficiency measures, including a thermal storage tank with a phase-change material that melts at 55°F, contribute to an impressive predicted site energy use intensity (EUI) of 21 kBtu/ft2. The design-build team has a direct financial stake in ensuring it reaches this target: 0.5% of the original contract value is at risk pending verification of the building’s energy performance after one year of occupancy. A significant percentage of structural timber and decking were reclaimed from an old warehouse on the site. Rainwater collection and reuse, together with exterior rain gardens that infiltrate water from the site, eliminate the need for a connection to the city’s overtaxed stormwater system.
The new Learning Resource Center at this ecologically minded private school in Corte Madera, California, includes a new library and technology center, art studios, classrooms and student services offices in 23,000 square feet of new buildings and 10,600 square feet of renovated space. A redesigned central courtyard, playground, and restored creek greatly enhance the associated outdoor spaces. More than 90% of the indoor spaces depend on natural ventilation, shading, and night-flushing with thermal mass in lieu of air conditioning, and most rooms have glare-free daylight from two or three directions. An underground cistern provides thermal storage while also holding rainwater from the rooftops for use in toilets and cooling towers, which provide cool water for use in radiant slabs without additional mechanical equipment. Using the project pedagogically, students helped with the creek restoration and will perform ongoing water quality monitoring and compare energy use for lighting and plug loads on a classroom-by-classroom basis.
Merritt Crossing Senior Apartments
Leddy Maytum Stacy Architects
One of the first projects near the Lake Merritt BART regional transit station at the edge of Oakland, California’s Chinatown, Merritt Crossing offers affordable senior housing on an abandoned site near a busy freeway. An independent screen wall buffers the units from the highway. Ceiling fans rather than air conditioning help provide summertime comfort. The project proved its mettle using four different rating systems: LEED for Homes Mid-Rise Pilot Program (Platinum Level), Build-It-Green GreenPoints (206 Points), Energy Star (first certified multifamily in California), and Bay Friendly Landscaping (104 Points). A full-scale mockup of a wall section provided important lessons for construction of the building envelope, which includes exterior rigid insulation, a vapor-permeable weather barrier, custom window profiles, and rainscreen cladding. The mockup was air- and water-tested to ensure its performance.
Pearl Brewery/Full Goods Warehouse
Lake|Flato Architects with Durand-Hollis Rupe Architects
A new master plan that is revitalizing a long-derelict section of San Antonio’s inner city is crowned by the adaptive reuse of the 67,000-square-foot Full Goods Warehouse into vibrant retail and office space. The designers added a mezzanine level to the sprawling warehouse, greatly increasing density, and provided extensive indoor-outdoor spaces. It also sports a 200 kW photovoltaic array, the largest rooftop installation in Texas. The full Pearl Brewery master plan includes residential units, a hotel, a farmers market, and an outdoor entertainment venue, anchoring redevelopment of the much larger River North District. Among the many reused elements from the historic brewery are 7,600-gallon beer vats now holding captured rainwater for landscape irrigation.
San Francisco Public Utilities Commission Headquarters
KMD Architects with Stevens + Associates
San Francisco commissioned this new 277,500-square foot, 13-story office building to concentrate administrative staff of its Public Utilities Commission, which was previous scattered in leased space. The building’s sculptural façade features both a dynamic art installation and wind turbines that provide a predicted 0.15% of the building’s energy. Rooftop photovoltaics are designed to produce nearly 6%. Light shelves in the window walls help daylight penetrate to the interior. Onsite blackwater treatment meets all of the project’s non-potable water needs. The project is seeking LEED Platinum certification. In support of San Francisco’s purchasing policies, the projects sought to avoid materials made of PVC, and the use of fly ash and slag in lieu of portland cement reduced carbon dioxide emissions by an estimated 7.4 million pounds.
Swenson Civil Engineering Building
Ross Barney Architects with SJA Architects
Civil Engineering is a new program at the University of Minnesota Duluth. Large gestures with significant environmental benefits include the decision to abut the new facility against an existing engineering building, which reduced exposed exterior walls in this severe climate and located the project on a parking lot rather than taking up vegetated open space. The designers also made large, column-free testing bays double as assembly spaces, saving significant floor area and cost. A displacement ventilation system enhances thermal comfort and air quality and reduces energy consumption in the high-bay spaces, contributing to a modeled overall 77% reduction in energy use.
The large entry hall and stairway on the north façade are not conditioned to the same level as the classrooms but instead serve as buffer zones. Rainwater is also managed on-site with rooftop vegetation, rain gardens, and French drains.
Yin Yang House
Brooks + Scarpa
This 3,800-square-foot Venice, California, home and office elegantly combines business and residential functions. Much of a smaller preexisting structure was retained in the new building, and the designers kept impervious site area to a bare minimum. Using primarily passive strategies, the project’s design beat California’s Title 24 Energy Code by 42%, which translates to 94% better than a typical home. All of the home’s electrical needs, and much of its total energy, are met by the 12 kW rooftop photovoltaic system. The building form is inherently self-shading, and all space are designed for natural ventilation and daylight. The owner and designers chose both materials and technologies based on a 50-year anticipated time before major renovations, which justified significant investments in quality and efficiency.

Amory Lovins, 50 Year Energy Authority


Amory B. Lovins, a 65-year-old American consultant, experimental physicist and 1993 MacArthur Fellow, has been active at the nexus of energy, resources, environment, development, and security in more than 50 countries for 35 years, including 14 years based in England. He is widely considered among the world’s leading authorities on energy—especially its efficient use and sustainable supply—and a fertile innovator in integrative design.

After two years at Harvard, Mr. Lovins transferred to Oxford, and two years later became a don at 21, receiving in consequence an Oxford MA by Special Resolution (1971) and, later, 11 honorary doctorates of various U.S. and U.K. universities. He has been Regents’ Lecturer at the U. of California both in Energy and Resources and in Economics; Grauer Lecturer at UBC; Luce Visiting Professor at Dartmouth; Distinguished Visiting Professor at the University of Colorado; Oikos Visiting Professor of Business, U. of St. Gallen; an engineering visiting professor at Peking U.; and 2007 MAP/Ming Professor at Stanford’s School of Engineering.

During 1979–2002, Mr. Lovins worked as a team with Hunter Lovins (his wife 1979–99). They shared a 1982 Mitchell Prize, a 1983 Right Livelihood Award (often called the “alternative Nobel Prize”), the 1999 Lindbergh Award, and Time’s 2000 Heroes for the Planet Award. In 1989 he won the Onassis Foundation’s first Delphi Prize, one of the world’s top environmental awards, for their “essential contribution towards finding alternative solutions to energy problems.” That contribution included the “end-use / least-cost” redefinition of the energy problem (in Foreign Affairs in 1976)—asking what quantity, quality, scale, and source of energy will do each task in the cheapest way. This economically based approach first permitted successful foresight in the competitive energy-service marketplace.

In 1993 he received the Nissan Prize for inventing superefficient ultralight-hybrid cars, to which ~$10 billion had been committed by 2000, and in 1999, partly for that work, the World Technology Award (Environment). He also received the 1997 Heinz Award, the 2000 Happold Medal of the [UK] Construction Industry Council, the 2005 Benjamin Franklin Medal of the [UK] Royal Society of Arts (Life Fellow), and in 2007, the Blue Planet Prize, Volvo Prize, honorary membership of the American Institute of Architects, Foreign Membership of the Royal Swedish Academy of Engineering Sciences, Time International’s Hero of the Environment award, Popular Mechanics’ Breakthrough Leadership award, and honorary Senior Fellowship of the Design Futures Council. In 2008 he was named one of America’s 24 Best Leaders by U.S. News & World Report and Harvard’s Kennedy School, and received the first Aspen Institute / National Geographic Energy and Environment Award for Individual Thought Leadership. In 2009, he received the National Design Award (Design Mind), Time named him among the world’s 100 most influential people, and Foreign Policy, one of the 100 top global thinkers. In 2010, he was Runner-Up for the Zayed Future Energy Prize.

In 1982, the Lovinses cofounded Rocky Mountain Institute, an independent, entrepreneurial, nonprofit think-and-do tank. RMI’s ~80 staff drive the efficient and restorative use of resources to help create a world thriving, verdant, and secure, for all, for ever. Ms. Lovins left RMI in 2002; Mr. Lovins is now RMI's Chairman and Chief Scientist. The Institute’s ~$13-million annual revenue comes from programmatic enterprise, chiefly private-sector consultancy, and from grants and donations. RMI’s balance sheet comes largely from Mr. Lovins’s having cofounded, led, spun off, and in 1999 sold (to the Financial Times group), E Source, the premier source of information on advanced electric efficiency.

Mr. Lovins led the energy design for his home (and RMI’s original headquarters), whose ~99% savings in space- and water-heating energy (to –44°C or –47°F) and ~90% in home electricity paid back in ten months with 1983 technology. An $18-million utility experiment he cofounded and -steered in the 1990s, PG&E’s “ACT²,” validated his claim that very large energy savings could cost less than small or no savings, e.g. in houses comfortable with no air conditioner at up to +46ºC (+115°F) yet costing less to build. He founded and until 2007 chaired RMI’s fourth spinoff, the advanced-composites technology developer Fiberforge Corporation, and is RMI’s lead practitioner—lately helping redesign >$30 billion worth of facilities in 29 sectors—in implementing for major firms the tenets of natural capitalism, which shared the 2001 Shingo Prize (Research), the “Nobel Prize for Manufacturing.” In 2004, he led a Pentagon-cosponsored synthesis of how to eliminate U.S. oil use, led by business for profit, and in 2007, became the first member of the Transformation Advisory Council for the Executive Chairman of Ford Motor Company. His other senior advisory relationships have lately served the leaders of Coca-Cola, Deutsche Bank, Holcim, Interface, and Wal-Mart and of several startup firms.

Mr. Lovins’s other clients have included Accenture, Allstate, AMD, Anglo American, Anheuser-Busch, Bank of America, Baxter, Borg-Warner, BP, HP Bulmer, Carrier, Chevron, Ciba-Geigy, CLSA, ConocoPhillips, Corning, Dow, Equitable, GM, HP, Invensys, Lockheed Martin, Mitsubishi, Monsanto, Motorola, Norsk Hydro, Petrobras, Prudential, Rio Tinto, Royal Dutch/Shell, Shearson Lehman Amex, STMicroelectronics, Sun Oil, Suncor, Texas Instruments, UBS, Unilever, Westinghouse, Xerox, major developers, and over 100 energy utilities. His public-sector clients have included the OECD, the UN, and RFF; the Australian, Canadian, Dutch, German, and Italian governments; 13 states; Congress; and the U.S. Energy and Defense Departments.

Mr. Lovins has briefed 21 heads of state, given expert testimony in eight countries and 20+ states, delivered thousands of lectures, and written 31 books and more than 450 papers, as well as poetry, landscape photography, music (he was a pianist and composer), and an electronics patent. In 1980–81 he served on the U.S. Department of Energy’s senior advisory board, and in 1999–2001 and 2006–08, on Defense Science Board task forces on military energy strategy. In 1984 he was elected a Fellow of the American Association for the Advancement of Science “for his book Soft Energy Paths and many other noteworthy contributions to energy policy,” in 1988, of the World Academy of Arts and Sciences, and in 2001, of the World Business Academy. Dr. Alvin Weinberg, former Director of Oak Ridge National Laboratory, called him “surely the most articulate writer on energy in the whole world today; "Newsweek, "one of the Western world’s most influential energy thinkers.” Dr. John Ahearne, then Vice President of Resources for the Future, remarked that “Amory Lovins has done more to assemble and advance understanding of [energy] efficiency opportunities than any other single person.” The Centennial Issue of The Wall Street Journal named him among 39 people in the world most likely to change the course of business in the 1990s; Car called him the 22nd most powerful person in the global car industry; and The Economist wrote in 2008 that “history has proved him right.”

How Passive House Makes Net Zero Energy Homes A Reality

Net Zero Energy
If you have lived off-the-grid for awhile like I have, you may also find the newly found interest in net zero building a bit amusing. Most of those who tout NZE do so from the luxury of a grid safety net, and those who want to go "off-grid" are typically more motivated, I think, for a spiritual or political purpose than the technical or environmental challenge. They never actually move to the cabin in the mountains or the yurt in the plains, or take the experience to fullest and design a stand alone system. But now the next thing is being served up in the form of Net Zero Energy living, a rather Zen-like approach to a built environment where one takes nothing out and ask for nothing in return.

The exciting thing is that technically speaking NZE is actually not too hard. What you need is a really, really big roof. The average home consumes just shy of 40 kWhs of electricity a day which very roughly equates to a 10kW solar system. At 10 watts a square foot you have a 1000 square feet of glass and silicon on the roof should be enough for an average house. Yikes(!) basically a very big shed roof covered in $50,000 or so dollars to make NZE a reality. I think I am probably low balling these numbers but they give the picture. Builders got smart and started lowering their home energy use as well to make NZE a reality, but let's face it, a really good home now is considered 30% better than code, and we really haven't talked about all the crap plugged in. So now the trend of NZE homes is looking at a upgraded house shell still with a big ol' honken solar array. The market message is if you want NZE it's going to cost you. Most folks are like me who could not afford anything near that, so I put up a tiny array and worked really hard at making sure I did not need the energy in the first place. Actually it wasn't hard to use 1/10th the average energy.

In the past year I have been working with group developing Rocky Mountain Passive House and while it took me a while to get to Passive House here I wanted to make the point that it's not about making energy that really counts for net zero energy consumption, it's about not needing it in the first place. That is what passive is all about. We cut 90% of all energy out of the equation which means that the building needs a much, much (much) smaller PV array. The size depends on how much energy the occupant uses to be fair, but we aim to give the project a real head start to NZE.

The dollar equation is even better. While a Passive House costs more than an average house to build for now, a NZE Passive House cost less than a comparable NZE project, and you get your upgrades for free (like some cheesy sales pitch). Think of it as opportunity savings: getting incredible windows and doors and a state-of-the-art envelope which equals comfort and craftsmanship for less money than plucking it down for a stack of PV on a roof, which frankly is not really a lifestyle enhancement. Get rid of the HVAC equipment costs and up-keep and the savings are durable and long term. While your spiritual or philosophical needs for low impact housing is met - http://rm-ph.com/about-the-passive-house-standard/comfort/ your actual comfortand budget is taken care as well. With Passive House your roof's solar collection potential is now available to feed things like an electric car you buy in a couple years, which makes your overall energy and environmental impact dramatically improved as well as future proofing your energy needs. Passive House makes the potential of a good energy citizen a reality, reducing the demand to a trickle and providing a genuine potential for eliminating dirty energy from your life both technically feasible and long term affordable.

Net Zero Energy (or if you prefer Zero Energy Building) can be measured in a handful of ways depending on what you include: embodied energy, equipment life span, line loss from energy supply, simple net-meter measuring. For instance if your meter says '0′ net energy consumption for the year this will not account for line loss or inefficiencies at the energy source like the coal plant, so the devil of what is reality is in the details. Producing energy onsite is not a panacea either; it typically is overused when system thinking is not applied and a market driven by products takes over. Don't get me wrong, I love photo-voltaic technology because it is solid state, will last longer than your roof and is utterly dependable. I have been off-grid for 16 years and no, it is not NZE as I use wood for heat and propane for hot water and cooking. For that you really need to be a good citizen and feed the grid (just without the extra mortgage).

10,000 Years of Building / History is our Future  
From The Build Well Forum (www.ecobuildnetwork.org)
A place for the leading edge innovators and thinkers to talk, bounce ideas around, share interesting news, and simply be together.
Excerpt by Bruce King from "Tradition and Sustainability" © 2010 The Prince's Foundation / Compendium Publishing
“When I am working on a problem, I never think about beauty . . .
but when I have finished, if the solution is not beautiful, I know it is wrong.”
–R. Buckminster Fuller

Bucky Fuller worked in the same spirit as indigenous builders throughout human history. Use what is at hand, rely on your own and your community’s intelligence, adapt to your culture and climate, notice what works, and learn from your mistakes; the beauty will naturally follow. In the past century we have turned that on its head: We use anything we want, brought from anywhere on earth, we hire “experts” to design and build for us, we ignore our own culture and climate, and we often fail to learn from our many mistakes. For beauty in our buildings and communities, we rely on the strangely exalted tastes of the latest fashionable architects and trends, and on the myopic worldview of government planners and regulators. What happened?

We of the Industrial Revolution are made of oil. We grow our food with oil, we make clothing with oil, we move ourselves and our things around the landscape with oil, and we certainly build and heat our shelter with oil. We eat, wear, drive and live in oil; we are steeped in the mythology and ethics of oil ­–– the word “oil” being used here generically to connote the family of fossil hydrocarbons (petroleum, natural gas, and coal) that we began mining and using in earnest 250 years ago. The reader is probably wearing clothing containing some petro-materials, recently ate food grown with natural gas fertilizers, will today use a gas-powered vehicle, and will sleep tonight in a climate controlled with fossil-fuel energy. Perhaps you read these words by electric light, about half of which comes from a coal-fired power plant. All of this might be fine but for a few problems only recently coming to light: the many and huge toxic hazards to people and the environment that are oil and its by-products, the abrupt and unpredictable changes to global climate caused by the recent increase of carbon and other substances in the air, and, last but certainly not least, the fact that supply is limited. We’ve already used up half the oil we ever had. We were and still are like an adolescent child, with sudden access to the Internet and semiautomatic weapons, having power beyond our dreams but almost no wisdom or experience to guide our hands.

The way we build is very much a part of the global problem. We are hypnotized by the myth of the superiority of modern architecture, with the disastrous consequence of not seeing the many flaws in our work. We use gas and oil instead of good design, sun and wind to keep our spaces comfortable. We use toxic materials in the usually mistaken belief that they will give us nicer, dryer, softer, prettier surfaces.  What we have is a lot of cheap energy that makes up for the many flaws in our modern architecture. When that energy is no longer cheap, the buildings will no longer work very well, if at all.  How shall we break the spell?

A general consensus among those thinking about a sustainable future is that everything will become more localized.  Energy, food, water, textiles and building materials will generally come from a shorter distance because it won’t be worth the financial and ecological cost to toss them across the globe as we so routinely do today.

Dreadful as the notion may be to contemplate, we’re going to have to ease away from oil and machines, and use more of our hearts, minds and each other to build well.  Something wonderful is just now unfolding on Earth.

Thermally Modified Wood - so eco-friendly!!!




MATERIAL STRATEGIES

Innovative Applications in Architecture


JUST WOOD: THERMALLY MODIFIED TIMBER

Wood as a building material has many virtues including its impressive strength to weigh ratio, relatively high insulating value, beautiful grain patterns, warm color, and soft tactility. However, despite these admirable qualites it also has one key limiting factor: it’s natural propensity to absorb and hold moisture, resulting in swelling, warping, and ultimately deterioration and decomposition. For this reason, denser, slower-growing hardwoods such as mahogany, teak, and oak have historically been the most sought after species due to their limited absorption capacity, superior dimensionally stability, structural strength, and aesthetically consistency in color and grain.
However, softwoods such as pine, fir, spruce, and birch make up the vast majority of wood used today. Because of their inherent vulnerability to water, aging, and decomposition, wood used in exterior applications are typically either impregnated with a copper-based solution such as chromate copper arsenate, alkaline copper quaternary, or copper azole, or sealed and finished using petroleum-based polyurethanes, lacquers, and varnishes. These chemical treatments essentially transform a completely organic material into hazardous waste once it’s building use has expired. Alternatives to these metal and petroleum-based treatments are slowly gaining in popularity due to increased environmental considerations. One particularly promising alternative is the use of heat alone to transform the chemical and physical make-up of wood for exterior architectural use.

The benefit of thermally modifying timber has actually been know for over a century, and the detailed chemical processes involved in thermal modification is something well known to wood scientists. However, only in the past decade has a systematic testing and analysis made thermal modification a commercially viable process. Developed largely in Finland over the past ten years, thermally modified timber uses kilns set to a temperature of around 400° F for anywhere from 20-75 hours. During this prolonged exposure to high heat, the wood undergoes a series of complicated chemical and physical transformations that together dramatically increase the wood’s weather and fungi resistance, dimensional stability, and visual consistency.
The wood’s resins become chemically transformed by the heat into a natural water repellant that is essentially baked into the structural cellulose of the wood. Furthermore, the hemicellulose sugars which play very little structural role but are the most easily digested part of the wood and thus the primary attraction for water-born bacteria and fungi, is broken down and crystalized within a more rigid and inelastic structural matrix, greatly reducing the wood’s water absorption capacity. These chemical and physical transformations at the cellular level result in a building material with significantly decreased water absorption rates, increased resistance to fungi and biodegradation, and improved dimensional stability with a limited decrease in structural performance (likely due to decreased overall density). Furthermore, the natural chemical transformations in the wood result in a deep, rich coloration throughout the full cross-section of the timber. The thermal modification of fast-growing softwood species such as spruce, pine, birch, and aspen seems to offer an economically and ecologically viable alternative to both the chemical impregnation of softwoods and the unsustainable harvesting of tropical hardwood for architectural applications.

The Affect of CO2 on Climate Known Since 1800's ?!

AS POSTED ON green building advisor.com on MAR 6 2013 BY ALLISON A. BAILES III, PHD, GBA ADVISOR
I'm new to global warming. I didn't hear about it until 1983. Even thirty years ago, the science behind the greenhouse effect and global warming was well known. French Physicist and mathematician Joseph Fourier is generally credited with being the first to hypothesize that the earth is warmed by its atmosphere and even that we humans can change the climate. That goes all the way back to 1827.

Meet Joseph Fourier

Fourier is known to all who study physics for his development of Fourier Analysis, which allows you to model mathematical functions as a series of sines and cosines, and Fourier's Law, which is the basic law of heat flow by conduction. The latter is known to beginning building science students as Q = U x A x ΔT, which is a simplified version of the full law.

What Fourier did was to calculate that the earth, because of its distance from the sun, should be significantly colder than it is. He calculated the amount of radiant energy hitting our planet and found that it wasn't enough to account for the temperatures we have here. In addition to considering the possibility of additional radiation from interstellar space providing the boost, he proposed that the atmosphere trapped heat and caused the warmer temperatures.
The really amazing thing about Fourier's work is that he did this before James Clerk Maxwell, Jožef Stefan, and Ludwig Boltzmann were even born. In the 1820s, scientists were still decades away from understanding that light, heat, electricity, and magnetism were all related. Maxwell put that together in the 1860s with his famous set of four equations that govern the field of classical electromagnetism.
Only then could Stefan and Boltzmann figure out their law of radiation, showing that the energy transferred by radiation is proportional to the fourth power of the radiating body's temperature and its emissivity. (The emissivity of materials is something we exploit in the making of low-e windows and radiant barriers). What Fourier did in the 1820s was revolutionary, but now this calculation is basic enough that it appears in introductory physics textbooks.

Further 19th-century advances in climate science

Several other 19th century scientists took up Fourier's work and studied radiation, absorption, and conduction in atmospheric gases, trying to get a handle on how our climate works. The Irish scientist Tyndall was one of the first to try to calculate how infrared radiant energy flows affect the climate.
Then came the interest in how carbon dioxide affected the balance of heat flows. Langley looked into this in the 1880s and calculated, incorrectly, that the earth's temperature would be only about -200°C (-328°F) were it not for the presence of CO2 and its insulating effect on the earth's atmosphere. It would actually be about -18°C (0°F), but hey, we're talking about someone doing this back in the 1880s. Lord Grantham’s mother, the Dowager Countess, was probably still hot and fashionable then!
One thing that Tyndall concluded from his work was that water vapor had more effect on atmospheric temperatures than carbon dioxide. In 1895, Svante Arrhenius gave a presentation to the Royal Swedish Academy of Sciences on the subject. Hist paper was titled, “The Influence of Carbonic Acid in the Air Upon the Temperature of the Ground.” (What they called carbonic acid, we know as carbon dioxide.) In it, he disagreed with Tyndall and said carbon dioxide was the more important greenhouse gas (though I'm sure he didn't use that term).
Arrhenius's study was pretty darn interesting. He wanted to know what would happen if the CO2 levels were different than the then-current concentration of 300 parts per million by volume. He calculated the resulting temperature for levels that were 0.67, 1.5, 2.0, 2.5, and 3.0 times as high and also looked at how it changed with longitude.
His results were quite similar to what scientists have found a hundred years hence: Doubling the atmospheric CO2 results in a temperature rise of about 6°C. Current work in the area ofclimate sensitivity puts his result just outside the 3°C ± 1.5°C range of modern climate research.

The good thing about science

As with most areas of science, the revolution happens first, and then the focus shifts to filling in the details. Thomas Kuhn discussed this in his wonderful book, The Structure of Scientific Revolutions, describing the revolutions as periods when we undergo paradigm shifts. I'm not sure the development of climate science represents as much of a paradigm shift as it does the creation of a paradigm, but the work of Fourier was definitely groundbreaking.
Since his work in the 1820s, we've added a lot of documentation to Fourier’s ideas about the greenhouse effect and global warming (including that the so-called greenhouse effect isn't what keeps greenhouses warm, but that's for another article). Scientists have tons of data on this subject and among them, there's not really any debate about (1) whether our planet is warming and (2) that our actions are a big part of the cause.
You can choose not to believe it, of course, but as astrophysicist Neil deGrasse Tyson said recently, "The good thing about science is that it's true whether or not you believe in it."
