HVAC Energy Reduction

These suggested HVAC energy reduction suggested within buildings are methods to achieve facilities energy conservation, without decreasing the level of comfort in the building.

Air Systems Specifics

  • Dual duct constant volume conversion to dual duct variable air volume operation.

  • Dual duct constant volume conversion to cooling only variable air volume operation.

  • Constant volume reheat conversion to variable air volume with reheat operation.

  • Constant volume reheat conversion to to variable air volume operation.

  • Multizone system conversion to variable air volume operation.

  • Unoccupied zone isolation.

  • Minimum outside air volume reduction.

  • Exhaust air volume reduction.

  • Exhaust air heat recovery.

  • Air system fan volume reduction.

  • Night setback operation during winter months.

    Air Systems General

  • Review hours of operation. Schedule OFF when possible.

  • Review operating temperatures. Adjust operating temperatures to just what is required, for both heating and cooling requirements.

  • Consider a building automation system to maximize occupied, unoccupied schedules.

  • Review air and water flow rates. Can they be reduced to reduce electrical and fuel costs?

  • Review the existing systems operations logic. If there is a BAS is it being efficiently utilized?

  • Are air system filters being changed often enough or maybe too often?
