Multifamily Trends - July/August 2006 - Point of
View
Multifamily development needs to lead the way in the
movement for sustainable buildings.
Sorry Kermit, It’s Easy Being Green
by John McIlwain
Multifamily is the best form of green housing
today—more gentle to the environment than the most environmentally
sound single-family home. Because of this, opportunities for multifamily
developers and the industry grow each year as Americans become more
environmentally aware. In fact, the industry should be at the forefront
of the U.S. environmental movement and a vocal advocate for sustainable
development.
This is beginning to happen. The National Multi Housing
Council is partnering with the Sierra Club and the Urban Land Institute
in advocating the benefits of denser development. Yet there is far more
the industry can do to create examples of environmental best practices
and promote environmentally sensitive development.
Compare any 200-unit single-family development with a
plain-vanilla multifamily building, also with 200 units. Single-family
developments today typically are built at a density of about five units
to the acre—the median lot size for U.S. single-family
developments in 2004 was just under 9,000 square feet, according to the
U.S. Census Bureau—meaning they require more than 40 acres for 200
homes, plus additional land for roads, sidewalks, and other
infrastructure. This requires thousands of square feet of paving for
internal roads, drives, connector roads, and sidewalks; thousands of
feet of water and sewer lines; and all the telephone and power lines
required to support the modern American household.
On the other hand, typical multifamily housing today,
whether rental or condominiums, is built at anywhere from ten units to
the acre for suburban garden-style developments to 100 units or more to
the acre for urban high-rise construction. The paving requirements are
minimal compared with a single-family development, and all connections
for sewer, water, power, and telephone lines are comparatively short and
efficient.
The location advantages for multifamily housing also
give it an environmental edge. Multifamily housing is often closer to
services, transit, and jobs than typical single-family developments, and
sometimes are even part of a walkable downtown or town center. The
result is fewer miles driven per resident for the same
lifestyle—and greatly reduced transportation costs for the
residents.
The point is a simple one: multifamily development is an
environmental home run, even before consideration of the type or quality
of construction or whether either meets special green standards. Even
environmentally sound single-family development has a far greater
environmental impact than the average apartment or condominium
building.
“For almost every new 2,300-square-foot house [the
median size of today’s new single-family homes], we have clear-cut
an acre of forest somewhere,” said Dan Chiras, an Evergreen,
Colorado, environmentalist, teacher, and homebuilder. He was quoted in
an interview for Katherine Salant’s “Housewatch”
column, printed under the headline “Today’s Housing Model Is
Unsustainable for the Long Haul” in the May 20 Washington Post.
“To produce all the metals and minerals used in construction, we
have dug a hole in the ground somewhere that is equal to the entire
volume of the house,” he said.
Added Salant, “There is an even more critical
reason to rethink the suburban lifestyle: the energy it consumes. More
than 40 percent of the planet-warming greenhouse gases that we
collectively produce every day are directly or indirectly tied to our
buildings. Half these buildings are houses.”
In the new era of expensive energy, global warming, and
a need for environmental responsibility, the American dream of endless
suburban expansion, lived out over the past six decades, is shifting to
a new, more balanced lifestyle in which multifamily housing plays an
ever-increasing role. There will be suburbs and suburban single-family
developments for years—maybe decades—to come, but over time,
more new housing will be located closer to an urban core, on smaller
lots, with smaller home sizes, and much will be built as apartments or
condominiums.
Meeting the New LEED Standards
This is not to deny the importance of using the very
best green materials and techniques available for multifamily housing.
The leading standards for green building are set out in the Leadership
in Energy and Environmental Design (LEED) green building rating system
created by the U.S. Green Building Council (USGBC). The problem until
recently has been that the cost of these new materials and techniques
could not be passed along to tenants or homebuyers in any but the most
limited circumstances because it would make the home price uncompetitive
in the market. However, participants in ULI’s second annual
conference on sustainable development, “Developing Green:
Sustainability Entering the Mainstream,” held this April in
Seattle, said this is changing. Developers and contractors all reported
that building to LEED standards and achieving certification for both
commercial and residential buildings added either no cost or at most 1
to 2 percent when done properly. This is a far cry from a few years ago,
when achieving LEED standards could add 5 to 10 percent or more to the
cost of a building.
The USGBC is a membership organization that, among other
matters, promulgates voluntary codes under the LEED name. Some codes are
still in development; others are now in their second iteration as
techniques and materials evolve through research and plain old trial and
error. Currently, the following codes have been promulgated or are in
development:
- LEED-NC: new commercial construction and major
renovation projects.
- LEED-EB: existing building operations.
- LEED-CI: commercial interiors projects.
- LEED-CS: core and shell projects.
- LEED-H: homes.
- LEED-ND: neighborhood development.
- LEED application guides: retail buildings (currently in
pilot), multiple buildings/campuses, schools, health care facilities,
laboratories, and lodging.
LEED-NC, the code that has been used by those developing
multifamily housing, can be found on the USGBC Web site, www.usgbc.org.
Developments can achieve different levels of LEED certification by
meeting a wide range of requirements that cover where a building is
located, how it is positioned on the property, and how it is
constructed, as well as the materials and equipment used in building it.
Though LEED certification is not a simple process, all the participants
at ULI’s “Developing Green” conference complimented
the USGBC for making it easier than it was in the past.
A number of suggestions were made at the ULI conference
on how best to work with the LEED standards and develop buildings that
can be certified under the program. Among the suggestions for developers
were the following:
- Choose a team experienced in green building. The number
of professionals and contractors with experience is growing fast, so it
should not be hard to pull together a strong team.
- At the beginning of the development process, convene an
“eco-charrette” with the team and other appropriate
stakeholders. This will allow reasonable goals to be set from the start
and ensure that everyone understands the goals and their role in
achieving them. The goals do not necessarily have to rise to LEED
standards, but it is important that the benefits and paybacks of meeting
each goal be understood. The eco-charrette also will make it possible
for each team member to coordinate with the other disciplines and feel
responsible for the project outcome.
- Begin value analysis—formerly called value
engineering—at the start; do not wait until the building is
designed and a price determined. For instance, materials are available
today that are more energy efficient, stronger, and less expensive than
those normally specified.
- Carefully study the local market, local contractors and
their practices, and local rules and regulations.
- Develop a proactive construction strategy; actively
manage site logistics, as well as waste management and recycling. Train
all the subcontractors regarding the goals and the role they need to
play to help meet them.
- Once the building is finished, commission it, just as
if it were a ship. Do a facility shakedown and tune all the equipment to
make sure it is working up to specifications; make sure the building
management is trained and following the right procedures, and educate
the incoming tenants as well.
The multifamily industry has a wonderful opportunity to
promote itself to the public and to local governments as the leading
environmentally sound form of residential development, especially if it
continues to reach out and partner with environmental advocacy
organizations.
As always, good examples are the best form of advocacy.
The more multifamily buildings that are built to green standards, the
more the industry can showcase itself and enhance its image. This can
only make new developments more acceptable to local communities and
their governments. The best news of all is that the cost of building
green is now comparable to that of traditional building methods. That
makes green building an example of doing well while doing good.
