Energy Efficiency Tips for Commercial Buildings

1. Regular HVAC Maintenance: Water, steam and air flow metering and monitoring can measure HVAC system efficiency and identify “leaky” valves or other potential system inefficiencies.
2. Damper and Actuator Maintenance: When working properly, dampers and actuators enable free cooling controls/programs to do their job. Maintenance performed every 3-6 months can cause a 5 ton compressor to operate only 20 hours less, energy savings can equate to $0.10 per kWh.
3. Heat Exchange Coil Cleanliness: Dirty condenser and evaporator coils reduce cooling capacity and make compressors work harder. Supply and return air temperature measurements with outdoor air resets is one of the most cost-effective maintenance steps that can be done on HVAC systems.
4. Demand-controlled Ventilation: Too little outside air is a health concern … too much is an energy waster. Using a CO2 sensor and controller helps you get it just right.
