A Davis engineering firm best known for
developing energy-efficient ways to cool homes will lead a
pilot program for certifying "green" homes
in California -- a major expansion of environmentally-friendly
construction, if it works.
The U.S. Green Building Council has chosen the Davis Energy
Group as one of 12 firms heading the program nationwide. The
Green Building Council plans to create a system for measuring
the green building features of new homes and assigning a rating
that buyers can easily understand.
The goal is to use less energy, save money and create less smog
-- a particular problem in the Sacramento area, where the air
generally doesn't meet federal ozone standards.
A similar program for commercial construction, Leadership for
Energy and Environmental Design (LEED), has operated since March
2000. Builders have signed up more than 2,000 projects for LEED
commercial ratings.
The council wants to expand the concept to include new single-family
homes. Developing a consistent green-rating system would help
homebuyers choose among competing projects, said Jim Hackler,
the council's LEED for Homes project manager.
Mortgage lenders and insurers also want a standardized system
to help them quantify the durability and financial benefits of
green building designs, he added.
The council hopes to roll out the LEED for Homes program nationwide
in 1 1/2 years. The group thinks it could eventually enroll 25
percent of the new-home market.
That would mean about 375,000 new homes annually, if homebuilding
continued at last year's pace of 1.6 million housing starts.
In Greater Sacramento, it would mean about 4,200.
Points and costs
Each of the 12 LEED for Homes providers must select four builders,
who will submit at least two home designs each for consideration.
One builder must be a nonprofit with a focus on affordable housing,
Hackler said.
"We are looking for homes that are under construction," said
Mark Berman, Davis Energy Group's business development manager.
Each house requires a review of the design, the construction
and a final home inspection. It's a tougher process than LEED's
commercial program, which does not require a performance test
after construction.
Builders win points for environmentally-friendly characteristics.
"We want to advocate cost-efficient technologies and redefine
what 'green' means in the housing market," Hackler said. "It
doesn't have to cost more. It's basic building science 101."
Using better insulation, tighter ducts and properly-sized air
conditioning systems would all earn points. Builders can also
boost their grades by reducing construction waste, not building
on farm land, and by buying lumber and other construction materials
produced within 500 miles of the building site.
Builders need a minimum of 30 points for
LEED certification. Ninety points earns a "platinum" rating.
The cost question could determine whether builders support the
program.
"We're in favor of any project we can do on a voluntary
basis," said Dennis Rogers, senior vice president of governmental
and public affairs for the Building Industry Association of Superior
California. "The issue for us is how do we start including
green-building techniques in production housing in a way that
doesn't drive the costs up."
The building council hopes to weave in standards from other
green building programs, such as the Sacramento Municipal Utility
District's Advantage Home program. SMUD's program awards two
levels of ratings for homes built with energy-saving components.
Spaceship look not required
Davis Energy Group, which employs 19, beat Southern California
Gas Co. and a few other competitors for the pilot program award
in California.
The Green Building Council won't provide any funding for the
pilot program, so the Davis firm plans to charge builders fees
of $150 and solicit funding from electric utilities like SMUD.
"The trick for all of the providers in this is figuring
out how to make this pay," Berman said.
In the meantime, he added, the firm will benefit by developing
relationships with progressive builders and expanding the company's
technological capabilities beyond energy efficiency.
Hackler said he hopes the pilot program will make the concept
of a green home more familiar to buyers.
"A lot of people think it has to look like
a spaceship," he
said, "or it's made of sod, or it has solar panels that
look like a screen door blew up on(to) the roof."
