CONSERVATION CLIPS
Building and Mechanical Codes Strengthened.
On September 15, 1995, Building Officials and Code Administrators Incorporated
(BOCA) accepted the 1995 Model Energy Code (MEC) as the energy conservation
portion of the National Building and Mechanical Codes. The building and
mechanical codes formerly allowed either MEC or ASHRAE Standards 90A and
90B for compliance. MEC requires more insulation in basements and walls
and better-insulating windows than the 15-year-old ASHRAE Standards. The
decision should improve the efficiency of new buildings in the Midwest,
Mid-Atlantic, and Northeast regions of the United States, where BOCA codes
are commonly used. Four states-Maryland, New Jersey, Oklahoma, and Virginia-have
laws requiring them to adopt the newest edition of BOCA codes when they
become available. BOCA had input from the Building Codes Assistance Project,
the National Conference of States on Building Codes and Standards, North
American Insulation Manufacturers Association, National Fenestration Ratings
Council, ASHRAE and some states. The 1996 edition of the building and mechanical
codes will be published early next year.

DOE Grant for State Building Codes. The
U.S. Department of Energy (DOE) has granted four states $500,000 to update
their state and local energy codes for new buildings. North Carolina, Kentucky,
Tennessee, and Georgia will use the funds for enforcement as well as development
of energy codes. Specific projects include training for state and local
code enforcement officials; seminars for builders, architects, and contractors;
simplified code enforcement documents; and an energy code hotline. Conservation

From Disaster to Efficiency. Habitat for
Humanity is rebuilding a 40-acre area devastated by Hurricane Andrew in
1992 with an integrated village of almost 200 affordable and efficient
family homes. The Jordan Commons project is located in Dade County and
is intended as a model for nonprofit housing and community developers.
Each 1,000-1,400 ft2 house includes natural cooling, high efficiency
appliances, solar water heating, water reuse, and access to public transportation.
The development will also include playing fields, parks, and three large
central buildings. The homes are expected to use 38%-48% less energy than
the average new home. Habitat for Humanity will monitor electricity use
in the homes for different appliances, including the air conditioner, air
handler, water heater, refrigerator, dryer, range, and clothes washer.

BPA Wins Contract Dispute. The Ninth Circuit
Court of Appeals decided in favor of Bonneville Power Administration (BPA)
on August 29 in a case brought by SESCO, an energy services company in
New Jersey, concerning a contract dispute. In 1993 BPA had terminated negotiations
with SESCO in a competitive bidding proposal for residential weatherization
because BPA felt that it would not be able to verify SESCO's estimated
savings. SESCO claimed that specifying its intended audit procedures or
describing how the company would choose which buildings to treat would
force it to release proprietary information. But BPA found it unacceptable
to set up a performance payment scheme based on an evaluation without this
information. The court determined that BPA made an "appropriate and rational"
decision to terminate discussions with SESCO. SESCO can appeal the ruling.

ICAA Loses Preferred Installers Decision.
Wisconsin Public Service Commission (WPSC) has rejected a request by the
Insulation Contractors Association of America (ICAA) to force two utilities
to stop publishing a preferred insulation contractor list. ICAA filed the
complaint against Madison Gas and Electric and Wisconsin Power and Light,
claiming that the utilities were unfairly extending preferential treatment
to select contractors who enrolled in utility-sponsored training of one
proprietary insulation system. "Since these companies automatically get
thousands of inquiries because of its utility franchise, steering customers
to specific contractors is unfair-simply because of contractor enrollment
in a utility-sponsored seminar series," ICAA wrote. WPSC's executive director,
Michael Kwart, however, responded that utilities do not prevent their customers
from hiring the contractor of their choice to perform conservation services.
"They do recommend that customers who want a certain kind of service, such
as air sealing, choose a contractor that is trained and competent to deliver
that service. That is the purpose of training." Kwart emphasized that no
contractors are excluded from receiving the training, the fee for attending
the workshop is nominal, and blower doors and pressure gauges are tools
of the trade. Energy and Housing Report, Sept 1995. Allan L. Frank

A Mail-Order House. A new kit is available
for a house that, according to the National Renewable Energy Laboratory
(NREL), uses only one-quarter as much energy as a conventional house. The
kit costs $19,000, as compared with $20,000 for materials, appliances,
and so forth, and nearly as much for labor to build a conventional house.
The kit house has 440 ft2 on the first floor, which is divided
between a cooking-eating-living space and a sleeping space, and 140 ft2
on the second floor. The first floor has an unusual bathroom arrangement:
there's a separate pedestal lavatory in the sleeping area, and the toilet
is accessible from all areas. If residents want to have a conventional
bathroom, they widen one of the two storage wings and place it there. The
house is heated with a solar system, backed up with a small gas log fireplace,
and cooled by a through-the-wall heat pump placed in the loft. The stressed-skin
foam panel walls insulate well; they consist of a sandwich of oriented
strand board enveloping a foam core. Since these panels are precut, the
house can be built in a single day. Drexel Insulation Report, July/Aug
