The Home Depot and USGBC Launch New Database of Green Building Products

The Home Depot and U.S. Green Building Council Launch New Database of Green Building Products
leedhomedepot.com offers information on products that may contribute to the requirements of the LEED® for Homes program

(Washington, D.C.) Mar. 7, 2012 – The U.S. Green Building Council (USGBC), in conjunction with The Home Depot®, has launched an online green home products database. The database: leed.homedepot.com is a special microsite withinhomedepot.com that features products geared toward green home building, many of which may contribute towards earning LEED® points and prerequisites for the LEED for Homes program, making it easier for homeowners and builders to find the products they need.

Currently, more than 2,500 products sold at The Home Depot are listed on the website.

“The LEED green building program helps homeowners measure green home performance across a range of categories, and products play an important role in achieving certification,” said Nate Kredich, vice president of Residential Development at USGBC. “This database represents just one of the many ways in which The Home Depot is advancing sustainable, efficient and healthyhomes by supporting green building and green products.”
“As the world’s largest home improvement retailer, we want to show our customers that building green can be easy and affordable,” said Lindsay Chason, senior manager of Environmental Innovation at The Home Depot.  “We have innovative, environmentally-friendly products that make LEED certification simpler.  Now through our partnership with U.S. Green Building Council and their LEED for Homes program, we are simplifying the process of bringing healthier, greener homes to reality.”

The green housing market is growing rapidly, having tripled since 2008.

LEED-certified homes are energy efficient, conserve water and vital resources, and integrate environmentally preferred products into the design and construction of a home. Nearly 18,000 housing units have received LEED for Homes certification, a number that has seen significant growth in recent years. Fifty percent of LEED for Homes projects are classified in the affordable housing sector, echoing a trend found in last week’s report from The National Association of Home Builders and the Wells Fargo Housing Opportunity Index (HOI). The data shows that nationwide housing affordability rose to a record level during the fourth quarter of 2011.

The USGBC and The Home Depot product database was a subject of intense interest during Modernism Week in California last month and debuted as part of the TED Conference during which Steve Glenn, CEO of LivingHomes, a LEED home builder since 2006 and the builder of the first LEED Platinum home in the nation, showcased LivingHome C6. C6 is the first affordable housing line from the pre-fabricated builder. Once sited in their final locations, C6 homes are designed to meet the requirements of the LEED for Homes rating system. The home was designed as part of a new partnership with Make It Right, a nonprofit founded by Brad Pitt and renowned architect William McDonough to build 150, Cradle to Cradle® inspired LEED Platinum homes in New Orleans’ Lower Ninth Ward. A portion of the proceeds from the sale of each C6 will help support the efforts of Make It Right.

USGBC strives to integrate the principles and practices of social and economic justice within those of sustainable building – ensuring that low-income families will maintain access to decent, safe, and affordable housing, even as society’s standards for what is decent and safe continue to rise.

Green building offers opportunities to reduce energy and resource consumption, enabling lower utility costs and critical savings for owners, funding agencies and residents alike. Green developments are also designed to offer superior indoor air quality to protect residents’ health and reduce health-care costs, and often provide better access to public transit and local amenities, decreasing the financial burden of transportation. The green home product database released with Home Depot will assist homeowners and green building professional to achieve these tenants of sustainability, health and affordability in their housing projects.

Worlds 1st LEED Platinum & NAHB Emerald Certified Gut Rehab

The goal of this home was to take a foreclosed home in disrepair and turn it into a high performance, healthy, utility efficient, environmentally responsible, and very durable home. Durability planning was used in conjunction with building science flashings and maintenance free exterior materials with lifetime warranties. The energy efficiency was improved by almost 300% on this home with air sealing, wall cavity insulation, exterior insulation, and windows with a .20 u factor. All materials used were non- toxic, low VOC, and had no added urea formaldehyde.

This home received two exemplary performance credits for MR 2.2. This was due to many extra points in that category for a high level of reclaimed materials usage, the use of locally produced products, and the use of low emitting products. All lumber used for framing in this house was reclaimed lumber. This remodel was done as an investment property, rehabbed and turned over and placed on the market for sale. The sales prices was comparable to other rehabbed homes in the local market. Construction costs on this project were impressively low at $55.00 per square foot.

This project was featured in the Chicago Tribune, Exerpt below.

Few homebuilding materials can’t be reused or recycled, said Brandon Weiss, president and owner of Elgin-based Weiss Building, who recently salvaged 99 percent of the material from a four-bedroom, two-bath home he rehabbed in Elgin.

“Everything that could get a second life, I donated,” said Weiss, who has become somewhat of an expert at reusing construction leftovers, filling in old crawl spaces with leftover bricks and using stones as landscaping accents.

While the tax benefits from donating construction materials are nice, it’s “our children’s future” that clinched the case for him, he said: “Our landfills are full. You can try to close that loop and reuse things.”

Homeowners who are planning a construction project should know that many waste companies can recycle discarded materials from trash containers and will prepare a report on the percentage of materials they are able to divert from landfills, said Jason LaFleur, regional director of the nonprofit Green Home Institute.

“If they can’t provide the service, you might want to think about going with someone else,” he said.

High Performance Cottage Home builder, builds his own home LEED

Being a LEED AP Homes and having completed almost a dozen LEED certified homes Jeremy vanEyk, Construction Manager & Vice President of Cottage

Home, has seen the benefits of what goes into a LEED home, and wanted to experience it first hand. For his family it was important to be close to the places they go the most. With the kids’ school only two blocks up the road and downtown being so close to this location, it just made sense. Working in the lakeshore environment and observing how homes react in some of the most drastic weather conditions also influenced how Jeremy chose to put the house together; choosing to go beyond building code and accepted building practices and striving to reach some of the highest standards in energy efficiency and sustainability. As it was built amongst some of the oldest homes in  the city, the house needed to blend in and age as gracefully as those around it.

Illinois Net-Zero-Energy masterpiece producing 40 percent more energy than it consumes

Starting with an eco-conscious dream for a truly green home transformed owner Michael Yannell’s Chicago residence into a $1.6 million, two-story 2,675-square-foot, four bedroom and two-bath Net-Zero-Energy masterpiece, producing 40 percent more energy than it consumes.

Completed in 2009, it is not only Chicago’s first LEED Platinum-certified home, but it has scored higher than any other LEED-certified project in history. Architect Farr Associates, builder Goldberg General Contracting Inc. and engineering MEP firm dbHMS created this urban infill project to utilize aspects of alternative energies through passive solar, solar grid technology, a greywater system and closed looped geothermal heating and cooling components. According to owner Michael Yannell, the main goal of this project was to create a more energy- and water-efficient, environmentally conscious place to live and to set an example by building a home as sustainable as possible. Incidentally, the green materials generally were no more expensive than conventional alternatives.

This Net-Zero-Energy residence was built using the U.S. Green Building Council’s (USGBC) LEED for Homes Pilot Program regulations. In order to earn the coveted LEED Platinum-certification, a project must meet the 100-point requirement, in which the Yannell residence scored 115.5. According to Net-Zero statistics, the Yannell residence generates 18,000 kWh/yr and uses only 12, 689 kWh/yr, earning the Yannell property an approximate $52,000 in tax credits in 2008-2009.

According to Jonathon Boyer, principal and director of architecture for Farr Associates, the permit and design processes were a challenge from the beginning, but thanks to help from a hand-picked team, deadlines were met and the project was a success.

“We put together a team of engineers, contractors, and a landscape architect, and the entire project was a team effort,” Boyer said. “Building Net-Zero-Energy is very difficult, and it requires cooperation between all components and consultants. We believe we’ve broken the sound barrier with this house, especially in the Chicago area.”

This being the first LEED-certified home came with obstacles along the way. According to Boyer, by creating new systems such as the greywater system, which recycles water used from the washing machine for the toilets, it was tricky trying to solidify the permit process. It has opened up new options for Chicago to consider when building more sustainable homes.

“It was a learning process, the city of Chicago was open to it. We didn’t have any hard and clear standards in the city for permitting this kind of system,” Boyer explained. “As a result of this house, the city of Chicago Committee of Standards and Tests is adopting a new state / city code for rainwater / greywater reuse. “We were pioneers and induced the city to think about changing permits to use more sustainable elements into the residential market,” Boyer said.

Other than utilizing alternative energies, the Yannell residence’s modern design integrated into the traditional neighborhood fuses form with function in a dense infill space. The home was built on a recycled lot where the previous building could not be salvaged. Boyer explained that typically energy-efficient homes are bland and lack style, but in this case, the owner and the building team wanted something well-designed and unique.”He [owner, Michael Yannell] wanted something aesthetically compelling and functional,” Boyer said.

The floor plan is designed as a dual-wing connected by a foyer, which acts as an entry and passageway, both equipped with south-facing windows to utilize natural light and garden views. The positioning of the wings help compete with the Midwestern climate year-round. With temperatures ranging from the high 90s in the summer to blistering zero-below winters, it was crucial to find the most sustainable design possible. Each wing has a uniquely shaped multi-functional V-shaped green-roof designed for stormwater management and for concealing the 48 photovoltaic grids on the home. “The butterfly pattern roofs are designed to screen the solar panels from view, while providing an ideal angle for the panels to harness the sun’s energy,” Boyer said.

Although the Yannell residence has received the highest LEED score, the materials it took to achieve the title are not unattainable for other eco-conscience projects. According to Boyer, “LEED for Homes is less than $3,000 for certification.” In this case, it assisted in the construction process by acting as a detailed guide when installing aspects such as air quality, water systems and when planning the positioning. Although there is no set specific standard definition for a Net-Zero- Energy home, Boyer said that there are other homes out there that claims to be Net-Zer-Energy, but many have only lowered their energy consumption. Only the Yannell property has the data to back it up. According to Principal of MEP firm dbHMS, Sachin Anand, “It’s [the Yannell residence] the future of housing and power generation where each home is a greenhouse emission-free power plant.”

Saranac McClellan Home goes platinum + zero energy in West Michigan

This 3-bedroom home with an attached 2-bedroom mother-in-law cottage provides living, workshop and home-office space for the homeowners and their mothers. It features barrier-free design throughout with zero-step entry, low thresholds, roll-in showers, grab bars, and knee-space under sinks and cooktops.

Go here to see an interactive website of the home with data on energy use compared to energy captured through PV

The super-insulated shell uses double-stud wall construction with 24,000 pounds of recycled cellulose insulation in the walls and attic, and a 6-inch layer of reclaimed foam insulation under the stained concrete floor. Heat from six flat-plate solar collectors is stored in an insulated 2,500-gallon water tank, which warms the floor and also provides most of the heat for domestic hot water.

High-efficiency wood stoves make up the balance of winter heating needs, and a small electric backup heater maintains temperatures when necessary. The home is designed to produce more electricity than it consumes on an annual basis.

The home has no lawn and is surrounded instead by gardens. The steel roof collects 2,000 gallons per inch of rainwater, which is stored in an 11,000 gallon cistern for garden irrigation and flushing toilets. A root cellar built into the hill behind the house provides zero-energy cold storage of fruits and vegetables.

As of October 2010 the Jay & Liz McClellan home officially earned a LEED Platinum rating, which is the highest of 4 levels of certification offered by the USGBC. They achieved a HERS index of 20, which one of the best in the state of Michigan.

This summarizes our energy production and consumption for calendar year 2011.

Statistics

Solar electricity produced: 6033 kW h (16.5 kW h per day)
Electricity consumed: 6150 kW h (16.8 kW h per day)
Non-heating: 5350 kW h,  heating: 800 kW h
Net electricity deficit: 117 kW h (-2%)

Discussion

“Our first 12-month report started April 1 2010 when we first activated the PV system and went through April 1 2011, but this report covers calendar year 2011 so there are a few months of overlap. For calendar year 2011 we fell just short of our goal to produce more electricity than we consumed, with a net deficit of 117 kW h for the year. Compared to our first 12 months of operation, average daily production dropped by 0.3 kW h but consumption increased 1.8 kW h. Some of that is due to having an additional family member living here since mid-year, and some is due to adding an upright freezer that uses about 1 kW / day.”

“Below is a graph showing the inside (red) and outside (blue) temperatures that we recorded throughout the year. Overall the house was very comfortable, with just a few days in the upper 70s during some hot summer weather when allergies made us reluctant to open up the house at night since our ventilation system filters out pollen from the incoming air.”

“The graph below shows the heat storage tank temperatures over the year. The big gap is when we drained the tank due to a leak, and we were able to get the tank warmed up again in the fall but not to the degree we would have liked.”

Determining Value of Solar Just Got Easier

The additional property value of solar has always been an issue in the industry. Homeowners and professionals both recognize the inherent asset value of solar just as you realize asset value for other home improvements such as a kitchen remodel or bathroom addition.  But quantifying that for real estate appraisers, brokers, and lenders has been an issue – until now.

Consistent appraisals of homes and businesses outfitted with photovoltaic (PV) installations are a real challenge for the nation’s real estate industry, but a new tool developed by Sandia National Laboratories and Solar Power Electric™ and licensed by Sandia addresses that issue. Sandia scientists, in partnership with Jamie Johnson of Solar Power Electric™, have developed PV ValueTM, an electronic form to standardize appraisals. Funded by the Department of Energy’s Office of Energy Efficiency and Renewable Energy, the tool will provide appraisers, real estate agents and mortgage underwriters with more accurate values for PV systems.

“Previous methods for appraising PV installations on new or existing construction have been challenging because they were not using standard appraisal practices,” said Geoff Klise, the Sandia researcher who co-developed the tool. “Typically, appraisers develop the value of a property improvement based on comparable properties with similar improvements as well as prevailing market conditions. If there aren’t PV systems nearby, there is no way to make an improvement comparison. When a PV system is undervalued or not valued at all, it essentially ignores the value of the electricity being produced and the potential savings over the lifetime of the system. By developing a standard methodology for appraisers when comparables are not available, homeowners will have more incentive to install PV systems, even if they consider moving a few years after system installation.”

The tool uses an Excel spreadsheet, tied to real-time lending information and market fluctuations, to determine the worth of a PV system. An appraiser enters such variables as the ZIP code where the system is located, the system size in watts, the derate factor – which takes into account shading and other factors that affect a system’s output – tracking, tilt and azimuth, along with a few other factors, and the spreadsheet returns the value of the system as a function of a pre-determined risk spread. The solar resource calculation in the spreadsheet is based on the PVWattsTM simulator developed by the National Renewable Energy Laboratory, which allows the spreadsheet to value a PV system anywhere in the U.S.

“With PV Value™, appraisers can quickly calculate the present value of energy that a PV system can be estimated to produce during its remaining useful lifetime, similar to the appraisal industry’s income approach,” said Johnson. “Additionally, a property owner thinking about installing PV can now estimate the remaining present value of energy for their future PV system and what it could be worth to a purchaser of their property at any point in time in the event a sale of the property takes place before the estimated payback date is reached.”

The tool is being embraced by the Appraisal Institute, which is the nation’s largest professional association of real estate appraisers. “From my perspective as an appraiser, I see that this is a great tool to assist the appraiser in valuations, and it connects to the Appraisal Institute’s recent Residential Green and Energy Efficient Addendum. It’s an easy, user-friendly spreadsheet that will not bog the appraiser down with a lot of extra time in calculations, and if they fill out the addenda properly, they’ll be able to make the inputs and come up with some numbers fairly quickly,” said Sandy Adomatis, SRA, a real estate appraiser and member of the Appraisal Institute.

Although the tool is licensed for solar PV installations, it could be used for other large green features in a home that generate income, such as wind turbines. The spreadsheet, user manual and webinar explaining the tool are available for download at http://pv.sandia.gov/pvvalue.

Solar Power Electric™ located in Port Charlotte, Fla., is an electrical contracting and solar integration company specializing in the installation of commercial and residential photovoltaic systems.

Highlights from Energy Star Version 3, Revision 05.

Revision 05 of the Version 3 guidelines has now been posted to the ENERGY STAR website. Partners are permitted to use this Revision immediately, at their discretion, but must apply this Revision to all homes permitted on or after March 15, 2012.

As part of this Revision, all major program documents have been updated. A Revision 05 Version Tracking Document, containing all of the specific changes in this Revision, has also been created. EPA strongly encourages partners to review these documents. The most substantial updates are summarized below:

Thermal Enclosure System Rater Checklist

 A new alternative to meeting 2009 IECC insulation requirements has been provided for homes that achieve ≤ 50% of the infiltration rate defined in the ENERGY STAR Reference Design.
 The timeline for complying with the minimum insulation levels required at attic eaves has been extended. In the interim, homes with space constraints are permitted to meet less stringent levels.
 Drywall adhesive (but not other construction adhesives) may now be used to seal drywall to top plates.
 Foam sealant may now be used in place of caulk to seal sill plates to foundations or sub-floors. Note that a foam gasket is still also required beneath the sill plate if resting atop concrete or masonry and adjacent to conditioned space.
 Batts that completely fill floor cavities enclosed on all six sides may be used, even when compression occurs due to excess insulation, as long as the R-value of the batts has been appropriately assessed based on manufacturer guidance and the only defect preventing the insulation from achieving the required installation grade is the compression caused by the excess insulation. This policy replaces the list of specific permutations of R-values and cavity depths that are permitted to be used.
 The methodology for evaluating compliance with the reduced thermal bridging requirements for mass walls that are not part of a passive solar design (e.g., CMU block or log home enclosure) has been clarified.

HVAC System Quality Installation Contractor Checklist

 Until credentials are available specifically for heating, cooling, and ventilation system designers, either the builder (or a firm or HERS Rater hired by the builder) or the credentialed HVAC contractor (or a firm or HERS Rater hired by the credentialed contractor) are permitted to design such systems and to complete Sections 1 through 5 of the Checklist. As always, the designer must comply with applicable codes and laws that regulate HVAC designers and HVAC designs. In all cases, Sections 6 through 12 of the Checklist may only be completed by a credentialed HVAC contractor.
 If there are no forced-air heating or cooling systems in the home, then Section 1 is the only section of the Checklist that must be completed. This is true even in such homes that use a forced-air ventilation system, because ASHRAE 62.2-2010 does not prescribe room-level duct design requirements for the ventilation system.

HVAC System Quality Installation Rater Checklist

 The maximum total Rater-measured duct leakage limit has been increased to 8 CFM25 per 100 square feet of conditioned floor area for all homes.
 Because the Checklist already limits total duct leakage, the mandatory requirement to seal and inspect duct boots has been removed. This change simply allows partners to use their judgment to determine when to seal duct boots to floors, walls, and ceilings to meet the total duct leakage limit.
 The method for performing bedroom pressure balancing tests has been clarified to require that all bedroom doors be closed and all air handlers be operating.
 The sone limits for multispeed ventilation and exhaust fans have been clarified by requiring that they be met when producing no less than the minimum airflow rate required.
 A footnote has been added to Item 2.7 and 2.8, which relate to balancing, to indicate that these requirements do not apply to ventilation ducts

10 green building predictions for 2012

Earth Advantage Institute, a fellow nonprofit green building resource and LEED for Homes provider that has certified more than 12,000 homes, announced its annual prediction of 10 green building trends to watch in 2012 in as press release. seconds such predictions and puts in some of our own thoughts.

The trends from a boom in certified multi-family construction to the advent of consumer friendly home energy technology.

  1. “Urban density. Millennials and boomers alike are choosing to live in the city where they can be closer to cultural activity, mass transit, more sustainable lifestyles, and other like-minded people, and builders must create more living space.  Builders are getting creative in gaining more living space through the construction of accessory dwelling units.”
  2. “Green multifamily homes. Earth Advantage Institute has seen a large spike in Northwest multifamily building certifications this past year, hinting that we might see a rise in certifications in 2012 as well.” has seen large spike in certified green projects for multifamily developments across the Midwest/
  3. “Energy upgrades start to drive home remodels. Builders and remodelers who are plugged into changing consumer preferences (smaller homes, reduced energy bills) have been able to capitalize on energy upgrade work.”
  4. “Deployment and testing of new materials. Although architects and builders are eager to try to new energy-saving materials and systems, these products require significant testing to ensure that the materials and benefits will last the life of the building and to avoid litigation.”
  5. “Consumer friendly home energy tracking devices. The introduction of the Apple-like Nest Learning Thermostat, and Belkin’s Conserve Insight energy use monitor that tracks energy use by appliance, are two of many sensor-based energy and water monitoring products for the home that are easy to use and help save money. Large electronics players like Fujitsu and Intel are also developing products, among others.”
  6. “Energy education for commercial tenants. The growing adoption of commercial building energy disclosure (New York; Washington, D.C.; San Francisco; Seattle; Austin) has building owners/operators and utilities seeking effective ways to educate tenants on saving energy.”
  7. “Transparency in home marketing. Builders, remodelers, and real estate professionals who can clearly educate their clients about the benefits and features of energy efficient, green homes will be those who earn the buyers’ confidence.”
  8. “More accurate appraisals. The ability for sellers and buyers to ask their banks for a green-certified appraiser means that the lending community will be open to the idea of the additional value and ROI offered by new certified homes and remodels.” – This is something or director is facing now. Attempting to get a proper appraisal for a moderate green home retrofit – you can learn more at http://grandrapidsgreenhomeretrofit.blogspot.com/
  9. “Broader adoption of residential energy ratings (and certifications!) for homes. Energy labeling systems are appearing in many states, offering estimates of a home’s energy consumption for homebuyers and homeowners.”
  10. Smart grid-compatible high-performance homes. Increasing numbers of home appliances are gaining the ability to monitor and report their own usage and to increase or decrease their electricity usage by remote command.
