Energy Conservation Measures (ECMs) The Issues We Find Save Energy
Low Cost/No Cost ECMs
► Equipment Scheduling
Reduce operating schedules where possible
► Simultaneous Heating and Cooling
Eliminate (dehumidification is an exception)
► Controls and Sensor Calibration
Is the BAS controlling to the actual conditions
► Control Volume of Outside Air
Minimize heating cold air, and cooling hot air
