<DIV><B><A name=37979>LBL-37979</A> COMPARISON OF DOE-2 WITH
MEASUREMENTS IN THE PALA TEST HOUSES</B> <BR>Abstract: <BR>The predictions of
the DOE-2 program for building energy analysis have been compared with
measurements in the Pala test houses near San Diego, California. This work is
part of the California Institute for Energy Efficiency's "Alternatives to
Compressor Cooling in California Transition Zones" project in which DOE-2 is
being used for parametric analysis of cooling strategies that reduce peak
electrical power in hot and dry climates. To establish the validity of DOE-2 for
this kind of analysis the program was compared with room air temperature
measurements in a "low-mass" however with conventional insulated stud wall
construction and a "high-mass" house with insulated concrete walls. To test
different aspects of the DOE-2 calculation, four different unconditioned thermal
configurations of these houses were considered: unshaded windows, shaded
windows, white exterior surfaces, and forced night ventilation. In all cases,
DOE-2 agreed well with the air temperature measurements, with a mean deviation
between simulation and measurement ranging from 0.2 to 1.0K depending on
configuration and type of house. Using a development version of DOE-2,
comparisons with inside surface temperature measurements were also made. These
comparisons showed good agreement. <BR></DIV>
