Can LEED Save Ohio?

Sustainable Renaissance in OH


The Great Recession has hammered Ohio. The unemployment rate topped 9 percent in its three largest regions of Cincinnati, Cleveland and Columbus. And the 2010 Census revealed that the cities of Cincinnati and Cleveland lost 10.4% and 17.1% of their population over the course of the decade. But in three recently released reports funded by Living Cities, CNT found that Cincinnati, Cleveland, and Columbus possess the transportation infrastructure and urban form to spark new and sustainable investment and LEED buildings as the economy recovers.

Senate Legislation Calls for Zero-Net-Energy Buildings by 2030

A Bi-Partisan Congressional Effort Lands the 2030 Challenge Targets Back on the Senate Floor The Energy Savings and Industrial Competitiveness Act of 2011 was introduced yesterday by Senators Rob Portman (R-OH) and Jeanne Shaheen (D-NH). The bill places meeting the 2030 Challenge target of zero-net-energy for new buildings by 2030 as the first item in a comprehensive strategy for U.S. energy reductions in the building and industrial sectors. Specifically, Sec. 101 of the legislation, Greater Energy Efficiency in Building Codes, directs the Secretary of Energy to “establish targets for specific years” with each target “higher than the preceding target” on a “path to achieving zero-net-energy” by the year 2030. The baselines for incremental updates of the codes are the 2009 IECC for residential buildings and ASHRAE Standard 90.1–2010 for commercial buildings. The first code update, the 2012 IECC, which will be released in about a month, meets the initial 50% reduction target of the 2030 Challenge. The 2030 Challenge has been included in numerous other federal, state, and local pieces of legislation. This most recent bill offers another opportunity for the U.S. to realize the energy reduction targets of the 2030 Challenge.

USGBC and Passive House Alignment

The US Green Building Council (USGBC) and Passive House Institute US (PHIUS) have released the following letter of alignment:

USGBC’s LEED for Homes rating system and Passive House standard are complimentary green building systems. Both programs share the goal of making the US building stock more efficient, comfortable and sustainable places to live. While the Passive House standard focuses primarily on greatly reducing the heating and cooling loads of the home, LEED for Homes also promotes efficient material use, site selection and development, and rewards projects that improve their water efficiency and indoor air quality.

A Passive House is a very well‐insulated, virtually air‐tight building that is primarily heated by passive solar gain and by internal gains from people, electrical equipment, etc. Energy losses are minimized. Any remaining heat demand is provided by an extremely small source. Avoidance of heat gain through shading and window orientation also helps to limit any cooling load, which is similarly minimized. An energy recovery ventilator provides a constant, balanced fresh air supply. The result is an impressive system that not only saves up to 90% of space heating costs, but also provides terrific indoor air quality.

LEED for Homes is a national, voluntary certification system, developed by national experts and experienced builders, that promotes the design and construction of high‐performance green homes and encourages the adoption of sustainable practices by the homebuilding industry.

LEED certification is based on 18 prerequisites and 67 credits across 8 credit categories. Beyond energy and indoor air quality, LEED for Homes also takes into consideration material selection, water use, site selection/landscaping, location to local amenities/mass transit and homeowner education.

USGBC works regularly with Passive House Institute US (PHIUS) representatives to further green home building nationwide. USGBC and PHIUS agree that building and certifying a Passive House is a seamless compliance path for LEED for Homes Energy and Atmosphere section, and that homes are beginning to achieve dual certifications. In fact, USGBC is exploring the incorporation of the Passive House Standard into future iterations of the LEED for Homes program.

LEED platinum-certified home in Chicago is a showcase for stylish living

The total cost was $1.6 million. That may seem like a lot of money, but if you look at any other custom-built house this big—it’s 2,675 square feet on a double lot in Chicago—it’s going to cost at least that much. Incidentally, the green materials generally were no more expensive than conventional alternatives.

ELLE DECOR: Why did you decide to build a LEED platinum house?

MICHAEL YANNELL: I wanted to set an example. I had been very frustrated with the construction I was seeing in Chicago. There are so many green options, but nobody was using them. People assume it’s too cold, it’s too cloudy, for solar energy. I wanted to show it could be done here.

ED: So it’s a kind of demonstration house?

MY: I’m not saying every house should be like mine. I’m saying, look at my house, take one detail, and start there.

ED: To accomplish that, you have to be willing to let the world see how you live.

MY: After I moved in I began giving tours constantly—usually an hour long, and limited to ten people, because there were always lots of questions. We started outside the house, and I explained the macro design of the home and then went room by room. I think people have been surprised by how beautiful the house is on the inside. I don’t know what they were expecting.

ED: So, give us the tour.

MY: The house is divided into two wings, so every room has a southern exposure. I think that’s a huge benefit, to not have any room be always dark. I never have to turn a light on during the day. In the winter months, it really has a beneficial psychological effect. The north side, by contrast, has only a few small windows—you’d lose too much heat otherwise.

ED: The solar panels all face south.

MY: Yes. But it doesn’t jump out as a house with solar tacked onto it. One of the things the architects insisted on was having as many of the solar panels hidden from view as possible. That’s one of the reasons the roof has that V shape. All the panels are on the north side of the V, and the south side of the V hides them from sight.

ED: How much did all this cost?

MY: The total cost was $1.6 million. That may seem like a lot of money, but if you look at any other custom-built house this big—it’s 2,675 square feet on a double lot in Chicago—it’s going to cost at least that much. Incidentally, the green materials generally were no more expensive than conventional alternatives. The big items were the heating and cooling systems. But you can take tax credits for 30 percent of those. So basically I won’t owe income tax for the next few years.

ED: How did you choose the finishes?

MY: Every material that went into the house has some environmental story. The exterior is a combination of durable fiber-cement board and Forest Stewardship Council–certified cedar, covered in a cocoa soy-based stain. I love the contrast of dark and light.

ED: And the interior finishes?

MY: In the south wing the floors are a dark brown recycled-porcelain tile, which is very earthy, very soft. In the north wing the floors are made from scrap lumber, which would have ended up in a landfill. It’s walnut, with a clear coat that gives it a warm, natural feel. In the bedrooms, I chose dyed-clay walls. Besides looking good, they absorb sound better than regular painted walls. And clay also absorbs humidity, which is a nice feature in the summer.

ED: Does the furniture have the same kind of environmental credibility?

MY: Much of it is steel, which is recyclable. That’s one of the reasons we bought a lot of furniture from Knoll. The house has a midcentury look, so Knoll was right up our alley. All of the fabrics are Greenguard certified.

ED: What about the art?

MY: We chose the work of a Venezuelan artist, Radames, who works with Plexiglas scraps. I liked the designs, but I don’t like Plexiglas, because it has a high petroleum content. So we asked if he could work with 3form, which is an eco-resin product. He came up with seven or eight pieces for inside and a sculpture for the backyard, so it’s a green art collection as well.

ED: Speaking of art, the house has gallery reveals—those subtle recesses where the walls meet the windows and door frames.

MY: We used reveals throughout the house. I had never even heard the term before. It became known as the “R-word” during the design phase. It added to the cost, but it was really important to the architects. I have to admit, I appreciate how good it looks.

What the Pros Know

Architect Jonathan Boyer, of Chicago’s Farr Assoc., says the house is designed to produce as much energy as it consumes. But, he adds, he knew it would get the point across only if it also looked good.

• Be flexible: Most of the materials were produced locally—a key green principle—but when he needed an attractive cement board, Boyer had to buy a European product.

• Do double duty: The butterfly roof provides shading in summer and optimal placement for the solar panels. The V shape collects rainwater, which is used for irrigation.

• Exploit technology: “Thanks to LEDs, we were able to flood the rooms with light,” says Boyer, “despite using fixtures so compact you hardly see them.”
