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.

Chicago North Shore Home Earns LEED Platinum

A Glencoe, IL home has just been awarded a Platinum rating by the United States Green Building Council (USGBC) LEED for Homes program, the highest level possible. The house is only the second new-construction LEED Platinum home in the State of Illinois and the first LEED Platinum home on the North Shore. View the LEED Project Snapshot

Glencoe, IL LEED Platinum exterior

The Washington Avenue home was designed by Nathan Kipnis, AIA of Kipnis Architecture + Planning of Evanston and built by Scott Simpson Builders of Northbrook. Owners Barry and Natalie Slotnick moved into the house in April of 2011 with their two young children.

Glencoe, IL LEED Platinum roofline

This home is unique in its commitment to staying within the aesthetic of the surrounding community while implementing a wide range of green goals. It’s one of the few LEED homes to take a non-modernist approach to its exterior, as well as being informed by traditional low-impact building philosophies. The home is classic in its style, form and proportions, yet modern in its use of materials, colors and systems. Green features include passive, natural ventilation; passive solar heating and cooling; water-efficient indoor plumbing fixtures including a waterless urinal; low and no-VOC finishes and fixtures; standing seam metal roofing; cement fiberboard siding; and prefabricated framing.

Architect Kipnis states, “The house was built for 40% of the cost of the first LEED Platinum home in Illinois and in a style that appeals to a much wider cross section of the public. While these homes can be thought of as pioneering efforts, if the goal is to engage the public then the design should be contextual to neighborhood and not be aesthetically shocking.  The Slotnick’s home is a perfect example of this.”

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.”

A Virtual CEU LEED Platinum Home Tour – River Escape

Green Builder Media, North America’s leading media company focused on sustainable living, recently announced the winners of its 4th Annual

 Green Builder Home of the Year Awards.

With entries from across the nation, the judges chose ten outstanding projects displaying the best and most cutting-edge green residential building. This year’s winning entries include designs that range from small and simple to super-efficient luxury proving that building sustainably can be done on any budget. We are proud to be one of the second time award winners in their four year history  (2009 GreenBuilder Home of the Year Award was for the “Vineyard” Project) . 

The “River Escape Project”
Resting in Michigan’s vacation wonderland, this home is located near the Muskegon River in Stanwood, Michigan with river access, thus the project name. This home is a site specific, 1,267 square foot Passive Solar Contemporary Style home built with BuildBlock ICF (Insulated Concrete Forms) from frost protected shallow foundation to the SIP 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. The exterior used two of our favorite products James Hardie FiberCement Siding and MiraTec trim. The interior of the home has stained concrete floor on the main level which makes for great thermal mass. The home was also designed with lifetime design principles and has zero step entries.

Part of the passive solar design is to have very few windows on the non-south sides 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. The windows in this home are made by

North Star (Canadian made) which uses a transparent low-E film between the panes of glass with a foam spacer to get a triple pane effect without the weight or waste of extra glass. The window U-value is .24 with a much higher Solar Heat Gain Coefficient (SHGC) on the South windows. In the winter, the sun will warm the living space during the day and shine on the concrete floors 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. It is wonderful to quietly contemplate the winter storms swirling through the open fields and feel pleasantly comfortable. The “River Escape” project is a Zero Energy Home (ZEH) thanks to the Passive Solar Design, 4.1 kW of Photovoltaic, Solar Hot Water and a 98% efficient boiler for the radiant floor heat and hot water backup. 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 and net-metering backwards every day since the home was completed in June. The home was built for $142.00 per square foot (before the 30% rebates from the Solar Hot Water, and Photovoltaic systems) making it more affordable for the general public. Besides the LEED for Homes “Platinum” certification (this project scored 32.5

points above “Platinum”) this home received 5+ Energy Star certification and a HERs score of 12. This is the lowest score ever tested in the State of  Michigan making it the most energy efficient house in Michigan. This home is 88% more efficient than a conventional code built home. The home is also ZeroStep “Silver” Certified (Lifetime Design or Barrier Free) from Disability Advocates of Kent County Michigan. 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, foundation, exterior walls, trim and siding. Every possible piece of unused material used in construction was recycled.
