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.

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

Socially & environmentally conscious homeowners certify in SE Michigan

Designed by Young & Young Architects, the contemporary “green” house is constructed of stone, cement plaster, copper, and glass. A bridge connects two sections of the home. The landscaping consists of indigenous, drought-resistant plants and grasses. all the materials used to build an ultra-green home in Bloomfield Township came from within a 500-mile radius, to meet LEED (Leadership in Energy and Environmental Design) requirements. But the idea for the house took root thousands of miles away.

“We travel to South America a lot, and when we’d fly over the jungle, we’d notice large swaths being clear-cut and burned,” says Art Roffey, who owns the home with his wife, Gail Danto.

“We spent time with the tribal people, and they would talk in terms of being custodians of their land, but they were seeing it disappear,” he says. “That was a big influence for wanting to build our home.”

The couple also noticed the recession of glaciers in the Andes. So, when they decided to build their house on Indian Pond, they were keenly aware of the environment.

The 1950s-era home formerly on the site was deconstructed, and all the materials were recycled and donated to the non-profit Architectural Salvage Warehouse of Detroit.

“We wanted to build a house that was beautiful and elegant and also honor the environment at the same time,” Danto says.

By all accounts, they accomplished that, with the assistance of Bloomfield Hills-based Young & Young Architects (Don Paul Young was the principal architect); LEED consultant Jim Newman, from Newman Consulting Inc. in Bloomfield Hills; Joseph Maiorano, from the Artisans Group in Royal Oak; and interior designer Diane Hancock, of Diane Hancock Designs.

At press time, the house was under review by the U.S. Green Building Council for Platinum certification — the highest level. The design also resulted in five 2011 Detroit Home Design Awards last March.At press time, the house was under review by the U.S. Green Building Council for Platinum certification — the highest level. The design also resulted in five 2011 Detroit Home Design Awards last March.

The home, which Roffey and Danto moved into in January 2010, is green as grass: Heating and cooling is geothermal; electricity is supplemented by 30 solar panels; a graywater system filters and stores water for non-drinkable reuse; the roof is recycled copper; and all appliances are Energy Star compliant.

Sustainability harvested teak was used extensively, as was lyptus wood. “You cut it at the trunk, and it grows a new trunk, which is the ultimate in recycling,” Roffey says.

Some of the furniture was designed by Hancock, who used recycled materials for fabric. Several Hancock-designed pieces were made by local artisans, Danto says.

Wherever possible, recycled or repurposed materials were employed. A circa 1900 leaded-glass window, bought at Materials Unlimited in Ypsilanti, is in the kitchen. Several Art Deco light fixtures and grates were also repurposed.

“We like integrating old and new,” Roffey says, and that sentiment extends to their extensive art collection.

“We have a lot of old Peruvian art,” Danto explains, “but we also have a large art glass collection, which is very contemporary.”

Weavings from Bolivia, Ecuador, and Peru mingle with Asian art. Several of the artworks are displayed in lighted niches throughout the 7,500-square-foot house.

“A natural swale cuts through the middle of the property and actually bisects it,” Roger Young says. The solution was to create two sections, eastern and western pods, linked by a bridge. Echoing Frank Lloyd Wright’s organic-architecture philosophy of bringing the outdoors in, the architects created the home so that it’s flooded with natural light from copious windows and skylights.

Young also strove for an organic flow, “to create spaces that aren’t rooms. There’s a big difference.” That effect was achieved by fewer walls and doors, which delineate space.

The outdoor property was also designed with an eye toward the environment.

“The whole landscape is indigenous materials, and all the plants are drought-tolerant,” Young says. But, he adds, it was a tough sell to local officials.

“In Bloomfield Township, as in most municipalities, you have to have lawn,” he says. “So we had to convince them that these hedge grasses grow to a certain height and then stop growing. Eventually, they got on board.”

For Young, that victory was sweet, because it’s paying dividends.

“When you walk into the Bloomfield Township building department, there’s a huge LEED wall with testimonials on how others can go green,” he says. “They use this house as a case study.”

Musings on LEED and Passive House

LEED for Homes has always required ENERGY STAR (a HERS rating of 85) as a prerequisite, and rewarded increasingly low HERS ratings with more points in the rating system. However, significant changes in the next iteration of the rating system (LEED 2012) will be even more performance-oriented, which should play well to Passive House customers. Especially those customers who want not only energy-efficient performance and good IAQ, but also those that want to go beyond and incorporate broader aspects of sustainability into their homes. This is where Passive House and LEED become intertwined.

A recent project in MN demonstrates how LEED and Passive House currently work together. But with the ENERGY STAR v3 changes that went into effect January 1, LEED proposes to have a “target index” based on an “absolute energy metric”, representing the maximum amount of energy a home can use. The thought is that this would:

• Better reward envelope / component improvement and design decisions.
• Factor in permanently installed plug loads not figured into a HERS rating such as driveway /swimming pool / spa heating, permanently installed appliances, and more.
• Large homes will no longer be able to “buy” their way into a lower HERS rating with solar photovoltaic / wind energy systems.
• Allows a clearer comparison between New construction and Existing construction.

This represents a mind-shift in the way that USGBC wants the industry to think about residential energy, focusing on total energy consumed, for example, on a BTU per square foot basis. This metric works well with Passive House, which is also a performance-driven standard that focuses on a similar metric. In the United States, a house built to the Passive House standard results in a building that requires space heating energy of 1 BTU per square foot per heating degree day, compared with about 5 to 15 BTUs per square foot per heating degree day for a similar building built to meet the 2003 Model Energy Efficiency Code.

Question to the group: What are your thoughts on this? If you noticed, there is a LOT of conditional language above. The reason is that right now, the rating system is open for public comment until Dec 31, 2010. Here is a blog I wrote with more details.

So, what does this mean for Passive House? Well, if you or anyone else has a vested interest in Passive House and want to shape the future of how the program works together with LEED, we encourage you to voice your opinions. We also have a great summary of the changes to LEED for Homes.

Finally, for more details on the metric, look at the end of the rating system under Glossary. The “LEED MmBTu Metric” definition provides additional information.

We welcome informal comments below.

The Vineyard Project

Nestled in South Western Michigan’s wine country this home is located next to a vineyard in Paw Paw, Michigan, thus the project name. This home is a site specific, Passive Solar Prairie style home built with BuildBlock ICF (Insulated Concrete Forms) from foundation to the roof. The exterior elevations of the home were designed with deeper roof overhangs, determined by using solar calculations, to both maximize and minimize the sun exposure based on the time of year. In addition, solar awnings on the lower level windows further shade the South-facing windows. The exterior used two of our favorite products CertainTeed FiberCement Siding and Andersen 400 series casement and awning windows. The interior of the home has stained concrete floor on all levels which makes for great thermal mass. The home was also designed with lifetime design principles and has zero step entries. Click here to view the project profile

art of the site specific design was to locate the garage to act as a wind break, to stop snow drifting from the northwest prevailing winds that we have here in Michigan. Part of the passive solar design is to have very little windows on the north side of the home, to keep heat from escaping through them. That is why this homes attention to detail is spent on the Southside of the home, where most of the homes windows face south. In the winter, the sun will warm the living space during the day and shine on the concrete floors on both levels which will store some of the heat gained, for gradual release. The roof overhang will shade the house from excessive solar heat gain in the summer, and west-facing glass is minimized to reduce cooling needs in the summer. ICF construction was perfect for this project because with ICF’s there are no concerns with noise and wind.

The “Vineyard Project” is a Zero Energy Home (ZEH) thanks to the Passive Solar Design, 3.3 kW of Photovoltaic, Solar Hot Water and the Geo-Thermal heating and cooling system. The home is also pre-wired for future installation of a Wind Generator. This home only uses about 600 kWh of electricity per month and has been generating a minimum of 20 kWh of electricity per day with many days’ net-metering backwards since the home was completed. The home was built for $134.00 per square foot (before the 30% rebates from the Solar Hot Water, Photovoltaic and Geo-thermal systems) making it more affordable for the general public.

Besides the pending LEED for Homes “Platinum” certification this home received 5+ Energy Star certification and a HERS score of 34. This is the lowest score every tested in the State of Michigan making it the most energy efficient house in Michigan. This home will be 66% more efficient than typical construction of a similar home of this size. In addition this homes toilets, faucets and shower heads are super low-flow for superior water efficiency. The home also has low-VOC paints, adhesives and finishes and uses recycled content for the flooring, decking, foundation and siding.

Energy Star Homes to significantly change in 2011

New Energy Star for Homes Guidelines

The U.S. Environmental Protection Agency has released the Version 3 Guidelines for ENERGY STAR® Qualified New Homes.

The new guidelines are quite a step up from the existing Energy Star guidelines, and specify two compliance paths. The prescriptive path applies only to homes that fall within the size limits of a Benchmark Home. Under the prescriptive path, the builder must meet the requirements of a reference design and mandatory testing requirements. The reference design requires insulation levels that meet or exceed the 2009 International Energy Conservation Code (IECC) requirements, as well as setting forth standards for HVAC equipment, domestic hot water, thermostats, ductwork, lighting, and appliances.

The Mandatory Requirements for All Qualified Homes require professional third-party rating for thermal enclosure, HVAC, and water management. Many of these measures are currently being done now in LEED for Homes projects, such as the pre-drywall inspection and the Durability evaluation and third-party verification.

In the Energy Star v3 performance path, homes must meet a target score on the Home Energy Rating Service (HERS) rating scale, using RESNET-accredited home rating software as well as meeting the Mandatory Requirements and having all insulation, windows, doors, and skylights meeting IECC 2009. The new 3.0 guidelines go into partial effect for most new homes on 1/1/2011, and full effect on 1/1/2012.

On a related note, LEED for Homes is also planning a revision in 2012, which will likely go out for public comment this fall. Many of the optional performance tests in LEED for Homes, such as outdoor air flow (IEQ 4.3), bedrooms and kitchen / bathroom exhaust (IEQ 5.3) and air supply (IEQ 6.3) testing will be required as part of the Energy Star v3 changes. Keep your eyes open to see how the next version of LEED for Homes will take into account the Energy Star v3 changes.
