Thesis: Comparison and Verification of Thermal System Performance
in High Performance Buildings.
Financial support for this research provided by the John S. Nelson Fellowship through
the Nelson Institute for Environmental Studies at UW-Madison.
Motivation
• Commercial and laboratory buildings are among the
highest in utility energy consumers, therefore providing
the highest potential for energy savings.
• Modern trends in construction, particularly large
buildings (~300k ft2), show high interest in energy
conscious design methods by way of programs such as
USGBC LEED*. However, the investment and
implementation of such energy efficient designs and
technologies are rarely verified post-construction
*United States Green Building Counsel’s “Leadership in Energy
and Environmental Design” program.
Goals and Objectives
• The Wisconsin Institutes for Discovery (WID) building on
campus at UW-Madison is a prime example of current
industry efforts toward energy efficient design and
operation.
• WID has been outfitted with various data collection
systems that enable the monitoring and trending of
building performance on an energy basis. This data has
been made available to the Solar Energy Lab.
Research Sequence
• Verification and error analysis will first be
conducted for the on-site data collection
system(s).
• Once data is confirmed, an analysis on the
performance of two major thermal system
components:
– Geo-Exchange Heat Pump
– Air Energy Recovery (Enthalpy Wheel)
