How HVAC Control Systems Help
A great way to improve the efficiency of heating and cooling systems is to incorporate control strategies that ensure systems are used only when necessary. Common control strategies include ENERGY STAR qualified programmable thermostats, multiple zones, and CO2 demand sensors. These strategies can be specified on new heating and cooling systems and retrofitted to older systems as well.
- ENERGY STAR Qualified Programmable Thermostats: These simple, easy to install thermostats allow convenient night/weekend setback to save you money. Models range from $50 to $200 depending on the desired features and usually include manual overrides to ensure comfort for late night workers.
- Multiple Zones: By dividing your facility up into multiple heating and cooling zones, your system can deliver more efficient heating and cooling by eliminating inaccuracies from a central sensor point. In addition, building occupants in different areas can adjust the temperature to meet their actual needs. If your facility has many rooms or floors, multiple zones are recommended.
- Demand or CO2 Sensors: Most heating and cooling systems draw in ventilation air by assumed occupancy, however modern technology has side-stepped this by designing systems that actually can regulate the air quality of your facility by measuring the amount of CO2 present. The result is more energy-efficient operation and better air-quality.
