LEED in trouble?

Henry Gifford of Gifford Fuel Saving Inc filed a federal lawsuit against the United States Green Building Council (USGBC). Here is a summary of the complaint from AnnArbor.com and Harvey Berman's article, "Federal lawsuit attacks LEED building rating system"

"At the heart of the 24-page complaint are claims by Gifford that the USGBC has deceived consumers and others by misrepresenting the benefits of LEED certification relating to energy efficiency and savings and attributes of the LEED rating system.

Some of Gifford’s criticisms of LEED include that it:
• is not based on objective scientific criteria.
• is not based on actual building performance data but rather on projected energy use.
• does not require verification of data submitted in certification applications and does not require actual energy use data.
• is not based on actual measurements but rather computer modeling of anticipated energy use levels."

The $100-million lawsuit alleges fraud, unfair competition, deceptive trade practices, and false advertising, among other things, reports TreeHugger.


The [alleged] problems with LEED wouldn't be such an issue if the program was totally voluntary. In the marketplace, problems would be identified, and other programs would be developed to compete, which is what has happened in the residential market. But many cities require civic buildings to earn LEED certification. See a brief list here [PDF]. This means that taxpayers are being forced to pay a specific third party--as opposed to say, a contractor or consultant, who have to present bids and proposals, and the most qualified candidate and/or lowest bid is chosen.

There is an argument that sustainable building should be codified (so that it is required just like life safety, accessibility, energy efficiency, and fire protection). Sustainability and green building could be seen as just as important as life safety, considering the impact of building on the environment and the damage to natural resources, pollution of air and water, production and release of carcinogens in the manufacture of products. From experience, a project can have the best green intentions, but the numbers just don't work. The more green building flourishes (or, in the case of this argument, is required) more products and competition could bring down the cost.

But codifying green building is a slippery slope, as present day conventional wisdom is often later proved incorrect or incomplete. For instance, there is legislation to eventually outlaw incandescent light bulbs. As I noted in an earlier blog post, there is research out there that suggests that Compact Fluorescent Light bulbs (CFL's) contribute to the carcinogenic "electro smog." I don't think there is enough research out there on the effects of CFL's to completely outlaw incandescent lights. I may be one of those crazy people loading up on incandescents like it's Y2K before they are outlawed, though there is hope with other technologies, like Light Emitting Diode (LED). 

The business of certification of green buildings is in its infancy, relatively speaking, and no organization can expect to get it all right in the first few rounds. This is especially the case in post-construction building performance, which will naturally take time to test and allow for trial and error.  Hopefully, this lawsuit and the attention surrounding it will serve to improve existing guidelines, and perhaps open the door for other nonresidential certifications to compete with LEED.

Full disclosure: I am LEED certified, but we have never worked on a LEED certified building. I would venture to guess that this is mainly about the cost of certification, not a lack of interest in green building. We have certified a Built Green home, and are currently working on Built Green, Energy Star, NAHB Green and Builder's Challenge certifications.

Hare House Phase 2 Construction Photos

New Hare House Phase 2 Construction Photos recently taken on a beautiful day in Friday Harbor. We are both designer and general contractor for the main house.


View from Harrison Street. The entry bridge provides access to the folly. The folly is clad with corten steel and clear cedar siding. 


The cantilevered balcony bring the living area outside, into the trees and suspended above the street. A full wall of glass offers views of the harbor and Mount Baker. 

See more photos and track the progress of the Hare House: Phase 2 on Facebook.

The Hare House cluster includes a Guest House with separate office, Main House and Folly structure on a challenging site in Friday Harbor. Driving forces of the design included the incredible views of Mount Baker and the desire to create a sustainable space for a couple permanently relocating to the island.

The clients want a flexible home that is cozy for the two of them yet opens to accommodate the extended family. Features of both the Main and Guest House include in-floor hydronic heat, advanced framing, rainscreen siding applications, permeable pavers, grasscrete parking areas, Watersense certified plumbing fixtures, Energy Star appliances and an elevator for aging in place.  The house is in the process of several sustainable third party certifications such as Built Green, Watersense, Builders Challenge and Energy Star.

Hare House Phase 2-Current Construction Photos

Hare House Phase 2 is currently under construction in Friday Harbor, WA. The main house and its accompanying "folly" joins the completed guest house on this difficult infill lot. The house is slated to achieve some national Green Building certifications, Energy Star and NAHB Green (Anna is a Certified Green Professional through the NAHB), as well Built Green, the local residential Green Building certification (the San Juan Channel House received its Built Green 3-star designation last year). We are also the contractor for Hare House Phase 2, through Studio How, our design build team. Studio How is participating in the US Department of Energy's Builder's Challenge

Forget Energy Star and LEED, Green Building is Passivhaus

This article and slideshow comes from Treehugger.com. Passivhaus is the latest buzz in the green building world, but it has been around since 1990, with the first buildings in Germany.

Passivhaus requires a maximum energy usage (120 kWh/m² per year), a blower door test, and an annual heating demand of less than 15 kWh/m² per year.

Green building rating systems will continue to battle it out for superiority, and Passivhaus is the latest to vie for its spot in the US.

San Juan Channel House is certified Built Green 3-Star


The San Juan Channel House has been certified Built Green 3-Star. View the current Built Green Newsletter here.


Points were earned for incorporating many green building techniques, including retaining a minimum of 30% of the trees on the site, setting aside a percentage of the buildable area to be undisturbed, using local materials, installing dual flush toilets, installing rigid insulation beneath the slab on grade, installing insulated headers and corners, using advanced framing with Greenguard certified insulation and a rainscreen system for siding, employing passive solar techniques, usin
g a hydronic heating system on separate zones with a high efficiency heat pump and geothermal heat pump, using concrete slab as the first floor flooring material, using Energy Star rated equipment and appliances, hard wiring for compact fluorescent lighting and installing dimmers, using no vinyl windows or carpet, detaching the garage, cabinets with no added urea-formaldehyde, using all low-VOC, non-toxic interior paints and finishes, reducing interior walls, and many waste-reducing efforts on site such as providing a detailed take-off list to framers and selling, giving away or recycling any construction waste.

Features earning Built Green points include the passive solar design, finished slab, local wood doors and windows and Energy Star appliances. Photo by John Sinclair, Concepia.
