Abstract:
This paper presents the analysis of energy performance
of single-family detached homes in three U.S. climates,
in order to determine energy-efficiency measures for
minimizing the loads and sizing requirements of
renewable energy systems that are essential for its offgrid,
off-pipe (i.e., utility-independent) operation. The
analysis used a DOE-2.1e simulation model of a 2000/
2001 IECC (International Energy Conservation Code)
standard house as a base case in three climate locations:
Minneapolis, MN, Atlanta, GA, and Phoenix, AZ. This
selection of measures and determination of loads for
renewable energy systems were accomplished by
analyzing the energy use using DOE-2.1e simulations
and heating/cooling load components using the Manual
J Average Load Procedure. The analysis showed several
aspects of building energy performance during different
times of the year in terms of available energy resources
that are critical for the sizing, utilization, and costeffectiveness
of renewable energy systems.
