Industrial Controls offers you 10 Tips for Increasing Energy Efficiency while also keeping IAQ in mind:

Commercial buildings can significantly reduce their overall cost of owning and operating an HVAC system by incorporating energy efficient equipment. In most cases, the more efficient equipment will be paid back through reduced operating costs in the first year.

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.
5. Linkageless Fuel/Air Controllers for Boiler Efficiency: Gain increased and repeatable accuracy in firing rate control. The increased precision you gain from a Linkageless control system can offer fuel savings of up to 10%. Linkageless control systems also work with dual fuel boilers to save even more!
6. Effective Water Heating Strategy: Use outdoor air resets and night setbacks of hot water systems. The hotter your water temperature the faster you lose energy through pipes and storage tanks.
7. Energy-Efficient Building Envelope: Additional indoor temperature inputs for optimized start up and shut down helps reduce heat loss and improves comfort.
8. Lighting and Electrical Systems: Use Occupancy sensors, suspended indirect luminaries and daylighting strategies. Keep abreast of efficiency trends in the latest IESNA Lighting Handbook.
9. Remote Energy Monitoring (Gas & Electric): Identify efficiency opportunities and facilitate load leveling and peak demand management.
10. Recommissioning: Studies show that continuously monitoring a building’s energy systems can lead to reductions of 10% to 15% in annual energy bills.
