As energy costs continue to rise, and studies indicate the average HVAC system consumes 39 per cent of the energy used in a commercial building, energy efficient HVAC design has the potential to bring big savings.

The rates vary based on occupant density, activity levels, floor area and other variables.

One of the most effective ways to offset the energy use penalty of treating fresh air is with an energy recovery wheel (ERW).

Using energy recovery wheels to reclaim energy from exhaust air can provide significant savings to the building owner while notably reducing the load on the HVAC system. They can help reduce the use of renewable resources and may help a building qualify as “green” in some locations.
