Energy Savings from Daylighting: A Controlled Experiment
published: 2005 | report number: 233-1 Demonstrating actual
lighting and HVAC impacts from high performance glazing and
daylighting strategies is difficult. While many schools and
other buildings have been designed and built using these
strategies, attempts to compare energy consumption with standard
designs must confront the myriad ways in which any particular
building differs from other buildings. This leaves open the
question of the extent to which measured differences in energy
consumption are due to deliberate design strategies versus other
uncontrolled factors such as operation schedules and building
orientation. This report presents the results of an experiment
conducted at the Energy Resource Station near Des Moines, Iowa
in two sets of identical rooms with independent lighting and
HVAC delivery systems.
