Abstract

Solar reflective, or cool roofs, are a demonstrated method of reducing air conditioning energy, particularly in cooling-dominated climates. Similarly, efficient lighting or mechanical equipment replacement programs have a reputation for achieving large savings in c01mnercial buildings. Savings estimates for such measures have historically used monthly utility bills, which only provide a macroscopic view of utility program savings. Advanced Metering Infrastructure (AMI) is commonly used in the U.S. by utilities for residential and commercial customers and provides not only a valuable record of changing premise energy use and demand profiles but in much greater detail than utility bills, if desired.

Partnering with Orlando Utilities Commission (OUC) in Florida, we developed a sophisticated weather-responsive methodology that disaggregates site space heating, cooling, and baseload energy using 15-minute AMI kWh and local weather data. This evaluation technique was applied to OUC's commercial "cool roofs" and "custom incentives" programs to provide improved utility program energy and peak demand savings estimates.
