Akron Summit Community Action, Inc. (Akron YouthBuild) partnered with Saint-Gobain through the Saint-Gobain Corporation Foundation with support from the Saint-Gobain family of companies, to complete a green renovation at 887 Garfield Street in Akron, OH. Saint-Gobain was founded in 1665 to manufacture glass for the Palace of Versailles in Paris, France. They are the Worlds largest building materials company. Recognized as a 2009 & 2010 Energy Star partner of the year by the US EPA, Saint-Gobain earned the 2011, 2012, & 2013 Energy Star Sustained Excellence Award, the highest level of recognition for outstanding contributions to protecting the environment through energy efficiency. The YouthBuild program started in 1978 in East Harlem, New York. The program concentrates on youths aged 16-24 who work full-time for 6-24 months while working toward their GED’s or High School Diplomas while at the same time learning job skills by building affordable housing in their communities.
The Garfield Project is the first YouthBuild Akron home to achieve the prestigious LEED Platinum certification. Saint-Gobain and its family of companies have donated a range of building materials and many hours of on-site support from CertainTeed Building Scientists to complete the green home renovation. The home features a heat recovery system and very efficient CertaSpray Closed Cell Foam Insulation which contribute to its energy efficiency. The home received a HERS score of 65 meaning that it is 35% more efficient than other comparable homes. In addition to energy efficiency measures the home incorporates several landscaping features that reduce it’s irrigation needs. For example, drought tolerant plants were installed along with a slow-growing grass that needs no fertilizers, little mowing, and relatively little water. The home harvests rainwater from its roof. These aspects have accumulated a 59% water reduction due to the sites landscape architecture alone.
CertainTeed (an affiliate of Saint-Gobain) donated many of the building materials. These materials contributed significantly to the overall efficiency and sustainability of the home. Grenite Engineered Stone Countertop’s were used and constructed with up to 85% post-consumer recycled content. Air-Renew Gypsum Board boasts industry only technology that removes VOC’s from the air and converts them into safe inert compounds, once they are captured in the board they cannot be released into the air. This Gypsum Board also aids in the reduction of moisture and mold. On the rooftop, LandMark Solaris – Solar Reflecting Roofing Shingles were utilized. They reflect the suns rays and reduce roof temperatures up to 20%.

Indianapolis Restored Home Gets LEED Platinum & Sells Fast!/2 Comments/in Local, Green Home Institute, Gut Rehab, Indiana, LEED Platinum, Single-Family Projects/by Brett Little
This home located on Elm St. in Indianapolis, IN was an abandoned space, built in 1910, that was bid on for redevelopment through the Southeast Neighborhood Development (SEND) organization’s Transfer and Transform program, which seeks to reinvigorate the community
“William Wagnon of Green Path Homes had been looking for an opportunity to do a LEED Platinum certified redevelopment on a house that could serve as an example of green building for contractors, home owners and a city in need of sustainability.” The house on Elm presented a perfect opportunity to showcase the economic viability of a green project as well as its added health and enjoyment benefits.
No subsidies or donations were taken to help the project along. “We wanted to do it as a market-rate project so that nobody could make an excuse for not doing it. That’s the point I wanted to make,” Wagnon said.
“The house now features around $7,000 worth of insulation, putting the home’s heating efficiency well-above most standards. The floor plan was changed to allow for a contemporary living style. Raised ceilings and other space improvements provide for maximum storage in the home. A rain garden now sits at the front of the house fed by a drain pipe from the roof. The backyard deck looks out onto a single-car garage, raised planters for growing vegetables and a patch of lawn.” Additionally, 100% of installed plants were drought tolerant further reducing irrigation needs. In total, the outdoor water savings plus the water savings due to the indoor installation of highly efficient faucets, showers, and toilets etc. results in a monthly water savings of 69% based on total water use. We were able to utilize the V4 Homes Workbook: Water Reduction Calculator to derive this number. A copy of the information is attached to the project profile at the bottom of this post.
The small 960 sq ft. 2 bedroom 1 bath home is located in an area with outstanding access to community resources such as public transportation. This well sealed home uses energy efficient appliances and is expected to save 47% on energy bills. Insulated piping adds to the efficiency of this home.
A central HVAC system equipped with an additional dehumidification mode adds to the health of the home along with the use of hardwood with a preference for FSC certified woods.
So much care was put into this home on Williams blog he writes … “Walter, who has does the exterior sheathing, rigid foam insulation and now the siding work is putting flashing tabs behind each butt joint on the siding. These joints will all be caulked, but it’s just a fact that caulk fails in a couple of years. But with the flashing tabs, any water that penetrates is redirected right back to the outside.
Brad nailed every shingle of the roof by hand. Yes, it takes much longer, but he knows each one is set. In building the soffit end caps, he cut fairly complex pieces so it could be 1 piece of solid wood, instead of having multiple joints that would require caulking.”
This project was the first residential home in the area to achieve the prestigious LEED Platinum certification.

WI Platinum 2.5k Square foot Home averages $30 energy bills/0 Comments/in Local, Certified Homes, Illinois, Indiana, LEED Platinum, Michigan, Minnesota, Ohio, Single-Family Projects, Wisconsin/by Brett Little
Thanks to Jetson Green for sharing this awesome post! (Article written by Christine Walsh on Nov. 28, 2013)
Architect Virge Temme of Sturgeon Bay, Wisconsin recently received the LEED Platinum for Homes certification for a private residence she designed near Gills Rock. The home was built by Bay Lakes Builders, and the plans were based on the collaboration of all members of the construction and design team so as to ensure proper integration of all systems. The electric and fuel bills for this 2,600-square-foot house were less than $30 per month on average during its first year. This is only the seventh home in Wisconsin to receive the LEED Platinum certification.
The building process started with the excavation of the meadow where the house stands, while the top soil was stockpiled and used for final grading later. Once the foundation was complete, the foundation forms were stripped and the below-slab plumbing and electrical runs installed. The builders continued with laying thermal tarp to protect the home from freezing rains. This was followed by the installing of under-slab insulation. All the joints were staggered and sealed in this process to prevent air movement between layers. Furthermore, all the penetrations through insulation were foam sealed, which protects against cold seepage and potential Radon gasses.
The roof was then installed, using 16″ I-joists to reduce thermal transmission and to provide additional insulation depth. The I-joists were placed directly over the studs below and the framed walls with studs at 24″ on center to reduce redundant top plate, which also reduced the overall framing materials need. The rafters were then screwed and strapped to studs to provide additional protection from wind. All the intersections were then foam-sealed.
To provide a continuous envelope 3/8″ OSB was added to the under side of rafters. Double 2-4 plates were screwed below the rafters to provide an electrical chase, eliminating the need for roof penetrations. The builders also used ladder framing, which greatly reduced the amount of redundant materials at wall-to-wall connections. Double-wall construction also eliminated thermal bridging and provided space for additional insulation.
The house has insulation values of R-45 for walls, R-60 for the roof, and R-30 for ground insulation. Together with passive solar orientation and specially-coated windows to introduce solar warming, and which also feature overhangs to protect from summer over-heating, there is no need for a furnace or a boiler for space heating.
Other sustainable features of the home include:
– Sustainably-harvested framing materials
– Recycled/recyclable metal siding, roofing and insulation
– Drought-tolerant plants replanted around the home
– Rain gardens for roof runoff
– Only low- or no-VOC paints, adhesives and insulation were used to ensure better air quality
– Floors are made of concrete and sustainably harvested bamboo
– Only highly efficient appliances, lighting fixtures, and plumbing were installed
– The building process resulted in almost no construction waste

Glenn Retreat LEED Home has Innovative Blackwater Design Feature/0 Comments/in Local, LEED Platinum, Michigan, Single-Family Projects/by Brett Little
The “Glenn Retreat” project exemplifies water use reduction both outdoor and indoor, with a 72% reduction in irrigation due in part by
the AdvanTex(R) Wastewater Treatment Systems manufactured by Orenco (R) that is a environmentally sustainable wastewater treatment technology that treats blackwater and greywater so well that the treated effluent can be re-used for subsurface irrigation (We achieved a additional LEED innovation point with this system). Along with Infiltrating Rain Gardens, Edible Forest Gardens, Extensive use of Native Drought Tolerant Plants and Eco Turf Grass on the outside and with low flow WaterSense certified toilet and fixture on the inside this project achieved almost every point under Water Efficiency in the LEED for Homes checklist. Our approach to handling waste water and storm water turned a negative attribute into a positive one; and created a drought tolerant and low maintenance landscape.
The site’s soil composition has high clay content, and coupled with a high water table makes for a less desirable building site. Fill dirt and sand were added to the center of the site to elevate the house a few feet above grade. Drain tiles and French drains were installed around the house to channel water into swales and rain gardens which we developed along the north, east and west property lines. This watering system has proven sufficient to support the wide variety of plant life added to the property. Our system eliminated the painstaking task of cleaning rain gutters too because we didn’t need to install any. The high water table also presented a challenge for the septic system. We selected an advanced system that uses a smaller drain field, and generates effluent certified by NSF International for subsurface irrigation. A native wildflower and prairie grass landscape is being developed on the septic drain field. Key Features Fabral Metal Roof (Energy Star) Exterior Construction is Advanced Framing @ 24″ o.c. 8″ of Agri based Open Cell Foam Insulation in attic. (R40) 4″ Ridged Foam Insulation under the Slab. (R-20) 3″ of Agri based Open Cell Foam Insulation on interior crawl space foundation walls. Exterior walls are Air Sealed with 5″ Cellulose Insulation (R-22) with 1″ Dow Styrofoam SIS Sheathing (R-5.5). (stops Thermal Bridging) James Hardie cement board siding. (with recycled content) MiraTec trim. (formaldehyde free, SCS Certified) 93% of Construction waste was diverted fro the landfills.

Metro Detroit's 1st LEED Platinum Gut Rehab Home/0 Comments/in Local, Certified Homes, Education and Events, Gut Rehab, LEED Platinum, Michigan, Project Type, Single-Family Projects/by Brett Little
The Ferndale home is 45.6% more efficient in its energy use in comparison to an average 2,000 sq. ft. existing Michigan home. The average is 3,948 kWh a month, while the Ferndale house used only 2,195 kWh. The overall cost for the electric use in the Ferndale residence is $74.56 a month, using 603 kWh, which is 34% less than the average, which costs $121 a month and uses 908 kWh. Heating for the Ferndale home uses 5.3 MCF and costs $23.85 a month, while the average uses 10.1 MCF and costs $127.46 a month. Altogether, the operation costs are 32% less than the average household to heat.
*The project team attempted to get actual past utility bills to determine the success of the upgrades. However, they did not know who the previous homeowners were, and since, DTE and Consumers Energy have outdated privacy laws, they do not allow for the retrieval of data without homeowner permission.See full Ferndale Home Energy Report
The purpose of this project was to revitalize an abandoned home in disrepair, and through environmentally-friendly construction practices, to transform it into an energy-efficient home. The house is 95 years old, had gone into foreclosure and had been vandalized while sitting empty, so it required a complete overhaul. Lee Purches, HP3 Group and project Green Rater helped ensure the quality and sustainability success of this home. Lee connected the owner with Herzog Homes, which was willing to pursue LEED certification with some budgetary constraints. The goal of this project was to restore this old house, but also make it better through green building design and LEED certification. The design team followed LEED protocol for local labor and materials, using renewable or sustainable products in aiming for Gold LEED certification.
The result is an efficient, practical, and affordable home that is no longer an eyesore in an established neighborhood. This home is the first of its kind in metro Detroit, setting an example for others to invest in Green Homes and to restore existing homes rather than build new. The home has been enlarged and now has a freestanding garage that also serves to capture water. The house also has its own high-efficiency controlled irrigation system that evenly distributes water in the front and back yards.The backyard contains a 200 square foot vegetable garden, which includes fruit trees. The garden benefits from the irrigation system and passive water collection to yield produce four to six months out of the year. The indoor air quality 10 times better due to the ERV and high efficiency furnace. The furnace is a two stage furnace that only runs at high capacity when necessary, and is 97% efficient.
The house is fully enclosed with open cell spray icynene insulation, from the basement wall all the way up through both floors to and the roof deck. The interior finishes, walls and trim contains almost no VOC other than the drywall glue and paint, which have low VOC ratings below 100. New Jeld-Wen windows were also installed with a U-factor and solar heat gain of 31 for additional energy performance and reduced air leakage.

College of Saint Benedict Senior Housing, LEED Platinum Certified/0 Comments/in Local, Affordable Housing, Certified Homes, Green Home Institute, LEED Platinum, Minnesota, Multi-Family Projects, Project Type/by Brett Little
The Centennial Commons townhouses were designed to be a sustainable part of the college’s landscape. The 32 townhouses were intended to be at least LEED Silver certified. The townhouse were originally considered in order to provide affordable housing for the 90% of students that live on campus, particularly the seniors. These townhouses were also built to represent the college’s commitment to sustainability, as well as the first college student housing in the state of Minnesota to have any LEED certification. Each townhouse has been outfitted with as many locally sourced materials, furniture, carpeting, and wood, as possible. The exterior is decorated with native plants and landscaping. Each townhouse is also individually metered for teaching students about their energy consumption and sustainability.
The 2-story townhouses were designed for a durable 100-year life and to be as efficient as possible. The townhouses provide housing for 125 students, accommodating 3-4 students in 4 bedrooms, with 2 full bathrooms. Each townhouse also has two bathrooms, laundry room, living room, kitchen and front porch. Also included in this project was the Commons Building to provide the community with a gathering space, study rooms, computer lab, kitchen and a multi-purpose room.
The townhouses are clustered for a compact development within half a mile of community resources; churches, libraries, convenience stores, fitness centers and shops. The building site was selected as it was not a habitat for endangered or threatened species, a wetland or public parkland. The townhouses also utilize outdoor LED lighting, non-toxic pest control and low flow plumbing inside. During construction 37% of waste was diverted, documented, and recycled while erosion control was also put into action in designing and installing the landscape.
One unique feature, according to Judy Purman, CSB’s Director of Sustainability, is that each unit is individually metered for gas, electricity and water usage. Judy Purman also stated, “Each apartment will receive a ‘mock’ bill so that the residents will understand what their actual usage is,” which in turn provides a “life skills learning opportunity. We’re integrating an educational component so that they will understand what it’s like to pay gas, water and electricity bills when they leave campus.”

Matchbox House LEED Platinum Certified – Ann Arbor/2 Comments/in Local, LEED Platinum, Michigan, Single-Family Projects/by Brett Little
The project started out with an intent to design LEED certified which is reflected in its unconventional design. The project was modeled after a matchbox and was designed to have four inner quadrants that slip past on another withing the out sleeve of the house, all on top of
a raised foundation. The Matchbox’s compact design contributed to it’s LEED Platinum certification as there was less conditioned area to work on. The architect gathered information from other contractors experienced in green building practices in order to produce a home outside the norm. The result was distinctive, efficient, and compact home surrounded by natural, permeable turf minimizing the impact of the house on the surrounding environment.
The house has four bedrooms, 1,738 sf of conditioned space and a one car garage. It has received LEED Platinum Certification. It has a HERS rating of 47 and many notable features, including FSC wood, reclaimed trim from demolished Michigan barns in the region, no conventional turf (no irrigation) and low flow plumbing fixtures. The house has no attic or basement so upstairs rooms have dramatic ceilings that begin at 3’-0” and end at 16’-0” with an angle ceiling matching that angle of the roof.
No conventional turf or irrigation system was installed around the home, and all fixtures and fittings (toilet, faucets, and showers) are very high efficiency, reducing the site’s water demand by 78%. The wood used in the cabinets, stairs, closets, doors, and upstairs floors are all FSC certified. The house itself is much more compact than a standard house, so much that the LEED threshold dropped by 10 points. The kitchen counter tops and decking are constructed are composite from recycled materials.
The home’s unconventional design earned it 1st Place in Detroit Home Magazine Design Awards 2013 for Contemporary House under 4,000 sq ft.
