Methodology to Calculate NOx Emissions Reductions from the Implementation of the 2000 IECC/IRC Conservation Code in Texas
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).
In 2001, the Texas State Legislature
formulated and passed the Texas Emissions
Reduction Plan (TERP), to reduce ozone levels
by encouraging the reduction of emissions of
NOx by sources that are currently not regulated
by the state. 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
IECC, 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 provides a detailed discussion of
the procedures that have been used to calculate
the electricity savings and NOx reductions from
residential construction in non-attainment and
affected counties using the eGRID database. The
previous paper by Haberl et al. (2004) presents
results from the application of the methodology
that is detailed in this paper.
