In this LEED Gold building, demand-controlled
ventilation was designed to use carbon dioxide
levels to modulate the ventilation system based
on actual demand. Depending on occupancy, this
retrofit may reduce energy usage 3 to 4 percent in
the Southeast climate, with a simple payback of
three to five years.
that drives real performance results for specific
ECMs and the building as a whole. For the M&V
of specific measures, various meters are available
for monitoring the demand and/or consumption
of equipment, while sensors, data loggers and
visual inspection verify that comfort and reliabil-
ity are maintained or improved. For M&V of the
whole-building performance, the team can use
original benchmarking tools such as the Energy
