| Summary | | The American Society of Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE) maintains a standard called Standard 90.1 that
regulates energy use in buildings other than low-rise residential buildings.
The 1992 Energy Policy Act required all states to adopt energy codes for
commercial buildings that meet or exceed the 1989 version of the standard and
succeeding versions if they save energy. An assessment was performed to
determine if ASHRAE Standard 90.1-1999 does save energy over the 1989 version.
The assessment used a large number of building energy simulations using the
DOE-2.1e simulation program to evaluate eight different building types, each
with two different floor areas, to estimate gas and electric energy
consumption. Six combinations of wall and roof types were modeled at several
different glazing fractions. The heating and cooling equipment simulated
included the six most common combinations. The results of the simulations were
weighted by using the Commercial Building Energy Consumption Survey data from
the U.S. Department of Energy and new commercial construction data from the
U.S. Census Bureau to determine the national impact. The analysis shows that,
on a nation-wide basis, the 1999 version of Standard 90.1 will provide no
meaningful reduction in source energy use, site energy use, or site energy
cost. |
