Overview of ..
The first principle of energy conservation is turning off equipment
when it isn’t needed. This part of the Energy Efficiency
Manual explains how to tailor the output of unitary and packaged
HVAC equipment to satisfy the actual heating and cooling requirement.
These activities often provide large savings, and they are relatively
The energy conservation measures presented here include devices
that reduce energy consumption in heating and air conditioning units.
They include setback thermostats, programmable thermostats, timeclocks,
time interval switches, motion sensors, people sensors, and contact
switches on doors and windows. In some situations, a reliable method
is to provide the power to HVAC equipment through a light switch.
None of these methods require special skill, but all of them require
You can also motivate energy conservation in heating and air conditioning
by using energy conservation signs effectively and by using security
personnel, maintenance personnel, and other facility staff to control
the HVAC equipment.
