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.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.”

Chicago North Shore Home Earns LEED Platinum

Glencoe, IL LEED Platinum exteriorA 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

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 rooflineThis 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.

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.

One challenge for the architects was the topography.

“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.”

Add a lot of Blown in Cellulose mix it with Geothermal out comes LEED Platinum

The project began with the deconstruction of a 40 year old summer cottage that we enjoyed using for many years. During the deconstruction phase, we were able to salvage most, over 90%, of the wood from the walls and ceiling.

The remainder of the house was recycled through Chef Container, our salvage
and recycling service provider. During the building process we used environmentally friendly materials such as low VOC adhesives, sealants, solvents and paints. In addition, our friendly lumber and supply contractor, Standale Lumber, was able to provide locally harvested materials whenever possible.
