Green Building Programs--A Growing Trend
by Jill M. Mayfield
Resource- and energy-efficient building programs are taking seed across
the nation and drawing in more traditional builders.

In 1991, Austin, Texas, and the city's municipally owned electric utility,
Austin Energy, launched the nation's first green building program, initiating
a trend that has slowly spread north, east, and west across the country.
At that time green building--using construction practices and materials
designed to limit a building's use of environmental resources--wasn't even
a blip on the radar screen of the nation's largest residential building
trade organization, the National Association of Homebuilders (NAHB). Nine
years later, green building has almost hit the big time. Seven well established
green building programs are thriving across the country, a new program
is taking off in Atlanta, and many other communities are beginning such
programs (see "Atlanta's Green Building Program Breaks Ground,"
p. 36). NAHB hosted the first national Green Building conference in Denver,
Colorado, last year. All the signs suggest that more sustainable building
methods are more than just a passing fad.
"Although I know of no official statistics to back up the claim, I use
the number of local builder programs and the inquiries I receive here at
the research center as indicators that the field is growing," says Peter
Yost, director of resource and environmental analysis at the National Association
of Homebuilders Research Center in Washington, D.C. Yost says he gets about
three green building-related calls each week from builders, home buyers,
manufacturers, and home builders associations. "The field is growing because
both builders and buyers are becoming educated regarding the value of resource-efficient
home design, construction, and operation," says Yost.
In April 1999, in response to an increasing number of requests, the
NAHB Research Center produced Guide to Developing Green Building Programs.
This 120-page guide describes program development and green building techniques.
It discusses costs, technologies, availability, and practicality; and it
includes references for everything from framing materials to xeriscaping.
More than 150 copies of the guide have been distributed to date.
Across the country, more than 6,000 homes have been built that qualify
for one of the nation's green building programs (see Table
1). It is impossible to state the total amount of energy and resources
saved through these programs, because most of the programs don't calculate
such savings. However, each of these homes cuts back on the resources needed
to build or operate a house and also provides a model for the community
of builders and prospective homeowners in the area. And while most of the
programs don't yet take into consideration such sustainable community concerns
as reducing travel by vehicles, some programs do address these issues.
For example, the Build a Better Clark Program in Washington has created
a program area for developers, with special consideration given to pedestrian
friendliness and site ecosystem protection. And the city of Austin's green
building program gives additional credit for such sustainable community
features as public transit within a 15-minute walk, location of a subdivision
near a hike-and-bike trail or park, or the presence of a backyard composting
bin.
Marketing Change
In trying to motivate builders to rethink traditional practices in new
residential construction, green building programs have chosen to abandon
the traditional means of causing change in building practices: the adoption
of codes and ordinances that force compliance with a local standard. This
approach can be successful, but it frequently creates clashes between the
governing body and the regulated party that can delay or compromise the
enactment of environmental and conservation initiatives.
"Codes are for life and safety issues," says Yost. "The best way to
achieve more resource-efficient construction is to demonstrate the value
to builders and buyers and have the market drive this phenomenon." Developers
of green building programs have tended to agree with Yost's approach, creating
voluntary marketing programs that entice builders to build homes that are
energy-, water-, and resource-efficient, and environmentally sound.
Today, green building programs fall into two categories. Six out of
the eight programs now in existence are extensions of the local, state,
or regional homebuilders association. These programs have arisen for reasons
as diverse as the communities themselves, but all seek to bring marketing
attention and positive public opinion to area builders. Many have also
been motivated by the desire to head off accusations by local environmental
groups that builders don't care about the environment.
The remaining two green building programs are affiliated with a city
or county government. These programs have been developed by government
officials who want to draw attention to the benefits of green building
for both the local citizens and the local environment. To some extent,
they were also developed to deal with problems municipalities have faced
in passing development and environmental regulations.
Austin Takes an Early Lead
The program that started it all was the City of Austin Green Builder Program,
now known as the Austin Energy Green Building Program, in Austin, Texas.
The program is a division of Austin Energy, the city's municipally owned
electric company. It evolved out of the city's aggressive energy conservation
programs, which stressed demand-side management. The Austin program has
rated 1,381 homes since 1994, when the most current version of the rating
system was started. On average, each home rated saves an estimated 1.33
kW.
"Green building is moving into the mainstream, where it is starting
to transform the market," says Marc Richmond-Powers, project manager for
the Austin program. "Buyers of homes and commercial buildings are now asking
for green features and buildings when they come to an architect's office."
The Austin program has two categories of membership: members, which
includes builders, architects, and developers; and associate members, which
includes material suppliers, real estate agents, lenders, and service providers.
Currently no fees are charged for membership or to rate individual homes.
Members must attend an initial orientation and then attend at least two
of the free monthly technical seminars held each year to maintain membership.
Members must also agree to promote green building to their clients and
to participate actively by having their homes rated by the program. Currently,
just over 100 builders and architects are members of the Austin program.
The Austin program rates buildings in four areas: residential, multifamily,
municipal, and commercial. The residential program rates new and remodeled
homes for energy efficiency, water efficiency, resource efficiency, health
and safety, and community. Ratings range from one to five stars, with five
being the most green. All projects must meet a baseline in each of the
rating areas. Once above the baseline, builders may choose any of various
weighted options. The more options chosen, the higher the final rating.
Staff members periodically verify ratings by visiting sites and by reviewing
construction documents. The Sustainable Building Sourcebook is the Austin
program's foundation document. This reference, which runs to more than
300 pages, describes in detail the building practices promoted by the program.
Marketing is a key component of the Austin program, as it is with all
voluntary green building programs. Members are provided signs and window
stickers for each rated home and a rating certificate for the buyer. Members
of the program are promoted by the city through radio, print, and television
advertising. Special events, such as a tour of green homes, provide a way
for builders to showcase their homes and for the program to generate awareness
in the community.
In the commercial, municipal, and multifamily program areas, staff members
offer free consulting services to designers and planners to help implement
sustainable features in their buildings and developments. Although there
is no rating system for commercial, municipal, or multifamily projects,
they must follow a set of guidelines in order to be considered green.
Colorado Builds Green
The Built Green Colorado program began in 1995 as the Green Builder Program
of Metro Denver. It was created through the joint efforts of the Home Builders
Association (HBA) of Metro Denver, the Boulder chapter of the HBA, the
governor's Office of Energy Conservation (OEC), the E-Star Home Energy
Rating Program (E-Star), and Public Service Company of Colorado (PSCo).
Built Green Colorado is a voluntary program that uses buyer demand and
market education to motivate builders to produce homes that are more energy-efficient,
more durable, and more comfortable, and that have better indoor air quality
than the average home. Builders are also encouraged to take measures that
conserve water, reduce pollution, and save natural resources in the construction
and operation of the homes.
In the Built Green program, the builder registers individual homes to
receive the Built Green designation. Each registered home must receive
an energy rating of at least four stars as certified by Energy Rated Homes
of Colorado or be built to the Model Energy Code 1993 (MEC 93) standards.
To qualify as Built Green, each registered home also must include a minimum
number of the green options in the Built Green checklist. The checklist
has 138 separate features in 21 categories. A builder must choose at least
35 features if all categories are used, or 38 features if one or more categories
are skipped. The Colorado program has registered more qualified homes than
any other program--roughly 4,000.
Doug Seiter, state coordinator for the program, prefers this point system
to a multitiered rating system. "It's a challenge to make a multitiered
system attractive to everyone. The Built Green program point system is
more inclusive and allows the builder much more flexibility," says Seiter.
That flexibility and the support of the Denver HBA have been key to the
Colorado program's active builder--even production builder--participation,
according to Seiter. "You have to have a program that is attainable at
a production level," says Seiter. Colorado's program has faced criticism
that the criteria are too easy. "My answer to that criticism is you're
not going to have a big impact on the building industry if the criteria
are too stringent." Seiter is quick to add that a program wouldn't be valuable
if its criteria were limited to standard construction practices. "It's
a balancing act," he says.
With the participation of larger builders, Seiter sees the program's
effects trickling down through the industry, even to suppliers. "The whole
building industry is changing, and building products as well," says Seiter.
He adds that recent media attention given to green building has made today's
consumer more aware and more likely to make good choices when purchasing
a home. "Given the choice, who wouldn't go with the better built home?"
says Seiter.
Sustainable Building in the Sonoran Desert
In Scottsdale, Arizona, home builders and prospective home buyers interested
in environmentally compatible homes can turn to the city's Green Building
program, which is also known as the Sustainable Building Program in the
Sonoran Desert to emphasize the unique sensitivity of the desert environment.
Scottsdale's program rates homes in six environmental impact areas: site
use, building materials, solid waste, energy, indoor air quality, and water.
A green building checklist and point system is used to qualify homes.
The checklist contains 150 green building options. Like Built Green Colorado,
Scottsdale's is an all or nothing program. A project is considered green
if it earns at least 50 points on the checklist.
A builder or developer may enter any number of homes in any given subdivision
into the program. The program is voluntary and open to all home builders
in Scottsdale. There is discussion among public and private agencies about
expanding the program into other communities around the valley and around
the state.
Every builder and designer who enters a home into the program is required
to attend a city-sponsored green building workshop or seminar. The workshop
serves as an introduction to energy- and resource-efficient and environmentally
responsible buildings. It features building experts in such areas as site
use, energy, building materials, indoor air quality, water, and solid waste.
As a consumer-driven program, Scottsdale engages in an ongoing marketing
effort to bring the program to the attention of the home buying public.
For Scottsdale's green builders, the program provides promotional packages,
expedited plan review, job site signs, a directory of local materials and
products that meet program criteria, workshops and seminars, and information
on how to obtain energy-efficient mortgages and a solar-energy tax credit
of 25% of the cost of an installed solar energy system up to a maximum
of $1,000.
Washington's Mushrooming Green Building Programs
Build a Better Kitsap is a program of the Home Builders Association of
Kitsap County, Washington, that promotes the use of environmentally friendly
features in new and remodeled homes. Like Austin, Kitsap assigns a rating
to homes. Homes enrolled in the program are rated by the association based
on the number of environmental features included in the home. Construction
projects that meet program standards are awarded a one-, two-, or three-star
rating certificate, with three stars representing the highest level of
achievement. The energy-efficient features used in a 2,400 ft2
home that recently qualified for the three-star rating are expected to
slash the heating bill by 50%. Without these features, this home would
typically cost $1,500 per year to heat, but computer modeling shows that
with them, the new homeowner will pay only $750 per year.
In a unique twist, the Build a Better Kitsap program provides builders
with an environmentally responsible homeowner's manual to be handed to
the buyers of qualifying homes. The builder can customize this manual,
which provides tips on such practices as composting and recycling, with
information on the green features of an individual home.
While the Kitsap program has been successful, it has remained small,
because the area has a stable population, and growth in the housing industry
there has been very slow. Clark County, Washington, which is experiencing
more rapid growth, has recently begun a green building program using the
same guidelines and materials as Kitsap. According to officials in the
Kitsap HBA, the Build a Better Clark program is catching on quickly. Seattle
is also catching on. The Master Builders Association of King and Snohomish
Counties is putting together a similar green building program, which is
expected to be functioning by late spring.
In the less than ten years since it began, green building has moved
in from the fringe and is now approaching the mainstream. Builders and
building officials around the country are asking questions about green
building--and asking how they can incorporate efficient, durable, and environmentally
sound construction into their communities.

Atlanta's Green Building Program Breaks Ground
The Greater Atlanta Homebuilders Association's Earth Craft House is the
latest green building program to take shape. Introduced in November 1999,
the Earth Craft House is a builder training and education program to encourage
environmentally friendly building techniques. Builders who sign up for
the program attend a one-day training course provided by the program's
partner, the Southface Energy Institute. Each registered builder must meet
certain criteria, which include a minimum number of options set forth in
the checklist of construction and material alternatives. In return, the
HBA of Atlanta will provide marketing support and materials to members
who are participating in the program.
For a green building program that is just getting off the ground, the
Earth Craft House is already exceeding expectations. "We were hoping to
have 50 Earth Craft Houses built in the first year," says Dennis Creech,
executive director of the Southface Energy Institute. "We already have
builder commitments to put up 500 Earth Craft Houses." Creech attributes
the program's early success to a well-developed marketing campaign and
to the fact that the program's design makes it accessible to mainstream
builders. "This program was not intended to push the fringe," says Creech.
The program's training workshop shows builders how they can incorporate
green building techniques into their building practices and still be profitable.
Another reason that builders have accepted the Earth Craft House program
so readily is that builders participated in its design. In particular,
builder input strongly influenced the certification process, according
to Creech. "The builders wanted to make sure that if they were building
to meet Earth Craft standards, everyone else in the program was also adhering
to those standards," he says. For every Earth Craft House, the builder
and the home buyer must sign off on a worksheet that details how the house
meets the program's standards. The documentation used to support the certification
process, such as load calculations and warranties, will be part of a home
buyer's closing documents.
For at least the first year of the program, Southface raters will conduct
a final inspection that includes a blower door and Duct Blaster test. Earth
Craft House sponsors--the Georgia Environmental Facilities Authority, Home
Depot, Andersen Windows, and Georgia-Pacific--will underwrite the cost
of these inspections for the first year of the program. |
