Top 10 Neighborhood in Nation just got greener with new LEED Home

The home at 1135 North Grove has earned LEED Platinum certification by the U.S. Green Building Council (USGBC) for achievement in green homebuilding and design. It will be the first residence in Oak Park to receive LEED certification, and this new custom home was built for less than $150 per square foot.

1135 North Grove is one of 40 homes in Chicagoland that have been certified using LEED (view the LEED Project Profile).  The single-family home was built by Wicklow Development Group, renowned for their expertise in green building and historic preservation. Through their commitment to green homebuilding, Wicklow Development Group is helping to keep homeownership affordable. Green homes have substantially lower utility bills[1] and may qualify for advantageous financing, lower insurance rates and government incentives.

“As a LEED Platinum home, 1135 North Grove is at the national forefront of green homes, and serves as a model of healthy and efficient living for the entire community,” said Jason La Fleur, Regional Director for the Green Home Institute, who also served as the third-party verifier for the project. “Their example can help us all to live better by reducing our environmental footprint, cutting the costs of our utility bills, and coming home to a healthier place to live.” La Fleur is hosting a free webinar on May 9 for real estate professionals interested in learning more about LEED homes.

1135 North Grove reduces energy use 66% below the typical new home built to code.  The four bedroom project features low-e argon windows, high efficiency lighting fixtures, detailed attention to preventing air leakage, and blown-in fiberglass insulation.  Other energy efficiency upgrades include a geothermal heating system which also provides most hot water heat, and a rarely-used backup electric water heater. An ultra-efficient electric induction cooktop is used in the kitchen. The roof angle was optimized for solar panels which produce electricity to power the home, without visually disturbing the home’s facade.

Located in one of the “Top 10 Neighborhoods in the Nation” according to the American Planning Association, the home features a very walk-friendly location in the heart of a neighborhood with many historic homes designed by notable architects.

Homeowner Tim Carey says, “Fitting a new construction home into a historic neighborhood creates a challenge for designers and builders. This project demonstrates that you can build a beautiful, traditional looking home, with a green design and features, yet keep with the character of an established community such as Oak Park.”

As a result of incorporating energy saving products and technologies, 1135 North Grove has achieved an impressively low 34 Home Energy Rating System (HERS) score. Additionally, the combination of electric using-and-producing systems at 1135 North Grove has resulted in affordable energy bills for the homeowners who have been living in the home for a full year. The house has had modestly low electricity bills, and as an all-electric home no natural gas is used, so there are no natural gas bills.

A heat recovery ventilator provides fresh air distributed throughout the home to keep it healthy for the homeowners and recovering some of the energy used to condition the air. Low VOC (volatile organic compounds) paint and locally sourced materials have been used throughout the house.  Proving building green can be done affordably, 1135 North Grove was built with a total construction cost of $145 per square foot after renewable energy incentives, below the Chicagoland average construction cost for custom new homes.

Homeowner of 1st LEED certified home in Ann Arbor tells his success story

** Update 9/15/2013 – This home is about to go back on the market – If you are interested is learning more now please contact the homeowner below.

Scott Phillips, Associate at The Inovo Group and homeowner of Ann Arbor’s 1st LEED Certified Platinum Home is a passionate blogger about the success of green his certified home. Scott gives us a unique perspective of his home that was certified back in 2008.  Beyond the requirements of LEED, Scott has installed 15kWs of Sunpower PV panels on his house and they have  been near net-zero energy over the five month period since the install.

This video is a description of the benefits of living in a green home by the homeowners of 723 Spring Street, Scott & Linda Phillips.  They discuss the positive life-style changes as well as the advantages of “living local” near down-town Ann Arbor.  Scott and Linda talk about needing fewer cars, water conservation, indoor air quality and their aspiration to be a net-zero energy home soon. 

“The project team started with a broad set of goals. Since these were spec homes, they needed to have market appeal – more square footage than the smaller homes in walking distance to downtown. At the same time, they needed to minimize footprint so that the lot would have lots of green space and areas for water infiltration. By building up and taking advantage of the long East/West axis of the lot, each home would have roof space to hold enough

solar panels to go net-zero. By creating open floor plans, the small footprints of the homes would be spacious and feel larger. Durability and excellent thermal performance would be addressed through a combination of Structural Insulated Panels (SIPs) and Insulated Concrete Forms (ICFs). The HVAC systems in the house would augment that performance and use the least amount of energy for the structure. To the extent possible, the significant non- invasive trees on the lot would be preserved. One last goal was to have the home fit in the neighborhood of older homes. By staggering the homes, we created more solar-gathering opportunities, and decreased the mass of the homes at the street. This helped the homes appear to be in scale, and by designing for the Victorian era, we were able to build in details that were similar to surrounding homes.”

“The location of our homes, downtown Ann Arbor, contributes significantly to the owners being able to live a low-carbon and healthy lifestyle. The homes are also very tight, and our duct leakage was virtually zero when tested before drywall. Good low-flow water fixtures and recirculating hot water save operational costs, as does the geothermal system. South side windows are 3 times the area of north-facing windows, and an ERV keeps the air fresh when the windows are closed.”

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.Ing Label Saranac

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.”

South East Michigan LEED Gold Certified Home

‘It’s not that easy being green,” sang Kermit the Frog. While that’s often true when it comes to green building, it is definitely getting easier, say Lynn and Charlie Arnett of Grosse Pointe Park. The Arnetts and their four children, three of whom still live at home, recently moved into one of the Detroit area’s first new LEED (Leadership in Energy and Environmental Design) certified, green-built houses.

The family had been living in a nearby 1950s house and needed more space. They thought seriously about building, but empty lots are hard to find in older, established neighborhoods such as Grosse Pointe, and they weren’t sure they wanted to trade in the frustrations of an older house (asbestos, lead paint, wet basements) for the different but equally challenging issues of newer ones (formaldehyde, medium-density fiberboard).Both have long been interested in environmental issues. Lynn worked in environmental law in Washington, D.C., and Charlie, a teacher, jokes that he recently found a button for the first Earth Day in a box when they moved.

After much thought and plenty of research, they decided to look for a lot where they could build an environmentally conscious new home. Ultimately, that search led them to a 60-by-175-foot corner lot where a condemned 1920s Tudor had been torn down.“We decided we wanted to walk the walk, not just talk the talk,” says Charlie of their decision to build. Doing so had its challenges. Green building has been in the forefront of the news, but mainly in the commercial arena. Green residential building is still fairly uncharted territory, say the Arnetts, especially in Michigan. Still, they were determined to make it happen.

Once they found their lot, they enlisted the help of Joel Peterson of Insignia Homes, a Grand Rapids-based builder whom Lynn had worked with on a former house and who had experience in LEED-certified homes. He led them to Wayne Visbeen, a Grand Rapids-based architect known for designs that successfully blend past and present.

The Arnetts wanted the house to be green but also to blend with the older Tudors and colonials on the block. “It was very important to us that the house fit into the neighborhood,” Charlie says. “We had the architect and builder do a Grosse Pointe field trip before we started.”Priorities included a vintage-style screened porch off the kitchen as well as a large open living space encompassing the kitchen and great room. The house would have six bedrooms and 41/2 baths and the kind of detail — wood trim, glass-knobbed doors, a stucco fireplace, exterior shingles — often found in older homes. Underneath, however, the infrastructure would be green.

LEED-certified houses include things such as geothermal heat, an air recovery system and a long list of environmentally approved materials, including insulation, windows, carpet, even landscaping. “Indoor air quality is very important to us, so we opted for no-VOC paints or finishes, and insulation made of shredded newspapers,” Lynn says. LEED certification is awarded in levels, with points given for each area of compliance. (For more information, visit the U.S. Green Building Council’s website at www.usgbc.org.) The Arnetts are waiting to hear if they have achieved platinum status, the highest level given, and have been investigating the idea of installing cutting-edge solar shingles, a product Dow is pioneering.

Lynn spent hours researching materials and contractors. They struggled to find cabinetry for the kitchen that was formaldehyde-free, ending up with an Indiana company. “You really have to ask a lot of questions,” she says. “It was a big education for us, too.”It took less than a year to build the Craftsman-influenced home. Now that the house is done, they’ve been working with Grosse Pointe Park-based interior designer Fatima Beacham and trying to fill it with “green” furniture — another area that hasn’t quite hit the mainstream yet.

“The problem with a lot of new furniture is that it is built with medium-density fiberboard that contains formaldehyde,” Lynn says. Formaldehyde has been linked to many health ailments. They admit there were times they were tempted to give in and take the easier way. “Staying on track and not letting ourselves be pressured to compromise was challenging,” Charlie says.“There were times I was tempted to cave, but Lynn kept me going.”

While building green is a bit more expensive than standard construction, tax credits and governmental rebates help, and prices should decrease as demand goes up, the Arnetts say. For their family, going green has been the right choice. “Once you get started, you want to do it 100 percent,” Lynn says.“When it comes to residential construction, LEED is still in its beginning stages. We’d love to be a resource for other homeowners. Hopefully our experience will make it easier for the next folks who want to do this. Even choosing a low or no-VOC paint for your next project is a good start.

The Isabella MN Ecologically Balanced Building goes to the Wolf Ridge Environmental Learning Center

Imagine that every building maintained the ecological balance needed to sustain life on earth. Then, imagine all of humanity motivated to take action, to make this dream a reality. An immensely complicated goal? Maybe. But if we put our fears of failure at the back of the bus, we will maximize the possibility of success.

An immensely complicated goal?  Maybe.  But if we put our fears of failure at the back of the bus, we will maximize the possibility of success.

Nature has provided us with many examples of “buildings” that achieve an ecological balance.  If we follow her example, it is indeed realistic to believe we can prevail.

An Ecologically Balanced Building (EBB), then, is the most advanced building possible for our times because it strives to replicate the ecological balance found in nature.

An EBB incorporates a multitude of interrelated, smart design choices, resulting in a building that virtually lives and breathes, is beautifully balanced, aesthetically pleasing, and is socially responsible and sustainable.  It must meet the following criteria:

1.       Generate more clean energy than it uses.

2.       Sustainably manage the use of water.

3.       Waste nothing.

4.       Adapt to new conditions.

5.       Work symbiotically with all other living things.

6.       Eliminate toxins and pollutants.

7.       Add beauty & justice to our world

We have the technology and the building science to achieve these lofty imperatives.  Fortunately, we are also able to monitor, measure, and verify claims that a building actually accomplishes its intended goals.  If we can’t prove our claims, they are meaningless.

The Isabella EBB Project’s initial goal was to create the most environmentally conscious building possible.  It targeted integrating all seven design criteria listed above.  Additionally, each criterion is monitored, measured and verified to prove, we can indeed live in balance with nature.  Following is a description of how the Isabella EBB Project integrated the design criteria:

1.        The Isabella EBB Project was designed to consume an annual energy load of 4.5 kBTU/sq-ft. It achieved Passive House Certification, (HERS rating of 3), as the design method to achieve this extremely low energy use index. This is similar to having a 200 MPG car in lieu of our standard a 25 MPG car. There are 9,700 Heating Degree Days in this climate zone & 189 Cooling Degree Days.  This was accomplished through the design and construction of thermally broken/R 55 walls and R 90 roof, the use of high performance windows with glazing selected specifically to optimize the solar gain for each orientation and an air tightness of .5 air changes per hour.  Using BTU meters on the heating distribution system, the system is to telling us if the design loads are being met.

2.       Because extreme measures were taken to reduce the energy loads for this building, renewable energy generation produces more energy than is needed to operate the building.  An 11,000 kWH per year PV system/8.4 kw peak load and 92 solar heat collecting vacuum tubes averaging 172,500 BTUs per day collect renewable energy. An experimental long term solar storage area using 16 inches of EPS  insulation on all six sides contains both waste taconite from mines and sand.  Excess solar heat collection in the summer, fall and spring are stored in this solar storage containment area under the building.  The monitoriong system is gathering temperatures of the containment area, the Kwh generated and used  and kBTUs for the collection system.  We hope to prove that we are producing more clean energy than we use and that this solar storage system can be scaled down for use in other buildings.

3. Two additional areas used for solar storage: a 500 gallon water tank and an 80 gallon domestic hot water tank.  These are also being monitor and measured to tell us how hot they are and how many days of cloudy conditions depletes the stored energy supply.

4. A small electric boiler is used for backup energy should the building need it due to depletion of solar energy.  This boiler is also being monitor to tell us if it is being powered on.  This has already proven to be a great diagnostic tool, as it told us that the relays and sensors were not properly sequenced because the boiler was turning on whenever the domestic hot water dropped a few degrees.

5. A Heat Recovery Ventilation System makes sure that the building and occupants are receiving the right amount of fresh air at the right temperature.  An innovative ground loop heat recovery system is connected to the HRV to preheat the outside air prior to being heated by the exhaust air from the building.  The success of preheating  the incoming sub zero temperature fresh air with heated water from the ground near the footings of the building is being gathered by the monitoring system.  We hope to discover a 10 to 15 degree preheating of temperature through this system.

6. A rain water collection system and vegetative roof assures that water continues to perform its job of replenishing the aquifers and supporting plants and animals that conversely support an ecologically balanced building.

7. Information being stored through the use of the monitoring system is allowing the building to be adapted to new conditions and future improvements. Security alarms, for example, are sent when power, pumps, temperatures or water levels are not performing as intended.  Historical data gives us the ability to adjust and improve the performance due to accessibility to baseline and historical data.

8. An extreme waste and material management system was incorporated in this EBB.  Sustainable & reclaimed wood products, fast growing bio-fiber products, repurposed materials (e.g., old doors for ceilings, old radiators fins for guard rails, old wine barrels for chairs, old chalk boards for sills, and reclaimed tile), contribute to achieving zero waste and low life cycle assessment values.

9. Two highly recognized environmental third party auditing/certifications (LEED and Passive House) were achieved for this project, certifying the project at it the highest level possible.  This achievement summarizes that there were many other features, to lengthy to describe for this entry, that make this project one of the most advanced ecologically balanced buildings of our times.

10. Social justice and beauty are parts of ecology that acknowledge the value of spiritually engaging people through art  while also supporting  the notion of providing equal access and opportunities to all people.  The Isabella EBB project embraced adding beauty through the creation of a place that is welcoming, educational, inspiring, healthful, intriguing and fun.  The importance of social justice was a goal that surfaced during the learning experiences of the project.  Consequently, the project will be willed to the Wolf Ridge Environmental Learning Center, as an extension of their educational mission of teaching and influencing students the importance of living in balance with nature.

Isabella EBB Project Team

The critical success factors for the project team included:

1.    keeping the integrated design process alive and well throughout the entire projects development,

2.    checking  boiler plate designs at the door,

3.    if the project team achieved the goals stated above the points would follow and certification would provide the auditing needed to further validate our assumptions.

3.    understanding that everyone was on a ecological educational journey

4.    that fearless, open and honest communication  was mandatory, (typical passive/aggressive northern climate personality styles would keep innovation from reaching its potential).

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.

Racine LEED home shows Modern Minimalism is Green

certified another LEED Platinum home in Wisconsin that features a picture-perfect location on Lake Michigan’s west shore in Racine, Wisconsin. The Scekic-Osborne home is a three-bedroom, 1900 square foot home — an example of the recent trend of home sizes retreating to more reasonable levels rather than the McMansions of yesteryear. The home, designed by Johnsen Schmaling Architects of Milwaukee, mixes modern architecture with a growing design trend known as “micro architecture,” which places a premium on petiteness, design and sustainability.

Helenowski Net Zero home in Chicago

Helenowski LEED Platinum Gut Rehab showcases urban zero energy

Chicago’s Yannell residence has gained a lot of notoriety as the first “net-zero” home in the city – capable of producing as much energy as it consumes. Yet another home on Chicago’s far northwest side, the Helenowski Residence, has joined the prestigious ranks of ultra-green LEED Platinum homes. In fact, it’s one of the highest overall point totals ever achieved for a LEED-certified home.

Helenowski Residence - Chicago Net-Zero LEED Platinum Home

Net-Zero LEED Platinum Home – Zukas Photography

This incredibly energy-efficient home was actually a gut-rehab of Helenowski Residence Scorecard a 1950’s brick split-level home, with a major addition, resulting in 3,300 total square feet. The owner has done an incredible amount of work focusing on the Materials and Resources as well as Energy and Atmosphere areas of the home. Some of the sample strategies include:

  • All drywall was recycled-content (for a $1 per sheet premium)
  • Salvaged douglas fir from 1800’s fire-damaged building for ceiling
  • Reuse or salvage for all new interior framing members
  • Diversion of +90% construction debris
  • Reclaimed copper for roofing and gutters
The home also has some exemplary energy characteristics that helped achieve a remarkable HERS score of 13, meaning the home uses 87% less energy than a new home built to code.
The remarkable energy performance was achieved by using soy-based spray foam insulation and a meticulous attention to air sealing in the project. The technical data is quite impressive. The blower door testing gave a result of 604 CFM at 50 Pascals.  With an estimated volume of 37,725 cubic feet of volume in the house, the air changes per hour at 50 Pa was 1.02, and the air changes per hour at natural pressure is .07. In other words, the home is very tight.
Other strategies contributing to the home’s energy performance include:
  • Triple-paned Pella windows with FSC-certified lumber.
  • Geothermal ground source heat pump for HVAC.
  • Solar photovoltaic panels and a vertical-axis wind turbine to generate electricity.
  • Motorized blinds control solar heat gain on west-facing (front) windows.
  • Extremely efficient cold-cathode lighting, up to six times more efficient than LEDs.
  • Roof is partially reflective white and part vegetative green roof.
The is truly a remarkable addition to the Chicago area’s growing green building inventory and offers many lessons for other builders in the area.  Detailed strategies with photos are available at the project’s web site, www.leedhomeliving.com, as well as by downloading the 1-page PDF Helenowski Project Profile that has assembled.
