1.2.23 Installation of an efficient destratification fan system

1.2.23 Installation of an efficient destratification fan system

Description

Thermal stratification is caused by hot air rising up to the ceiling or roof space because it is lighter than the surrounding cooler air. The same applies to cool air falling to the floor as it is heavier than the surrounding warmer air.  This means that HVAC systems have to constantly cycle on in order to maintain the overall building interior at a settled temperature. HVAC systems are typically over delivering either heating or cooling to compensate for this stratification phenomenon. To avoid this issue the air can be moved by an efficient destratification fan.

Benefits

  • Extremely simple to retrofit and/or install

  • The amount of HVAC equipment required for a building or space is reduced

  • Complement the HVAC system in any building as efficient air movement is the key to make sure an HVAC system operates at its maximum potential without wasting energy

Limitations

  • Spaces which are not tall enough to become highly stratified

Economic assessment

Affordable purchase and install price. Payback: Three months. Energy savings on heating and cooling costs by up to 50%.
