Abstract
Four areas in Texas have been designated by the
United States Environmental Protection Agency
(EPA) as non-attainment areas because ozone
levels exceed the National Ambient Air Quality
Standard (NAAQS) maximum allowable limits.
These areas face severe sanctions if attainment is
not reached by 2007. Four additional areas in the
state are also approaching national ozone limits
(i.e., affected areas)1. In 2001, the Texas State
Legislature formulated and passed Senate Bill 5 to
reduce ozone levels by encouraging the reduction
of emissions of NOx by sources that are currently
not regulated by the state2. An important part of
this legislation is the State's energy efficiency
program, which includes reductions in energy use
and demand that are associated with the adoption
of the 2001 IECC3, which represents one of the
first times that the EPA is considering emissions
reductions credits from energy conservation - an
important new development for building efficiency
professionals, since this could pave the way for
documented procedures for financial
reimbursement for building energy conservation
from the state's emissions reductions funding. This
paper reviews the procedures that have been used
to calculate the electricity savings from residential
construction in non-attainment and affected
counties. Results are presented that show the
annual electricity savings and NOx reductions from implementation of the 2001 IECC to single family
residences in 2002, which use the DOE-2
simulation program.
