Heating and Cooling Savings

Heating and cooling comprises approximately 40 percent of the energy used in commercial buildings, which is why outdated HVAC systems and other structural issues could be costing you.

Consider these ways to save:

  • Make sure your equipment is properly sized. The most efficient sizing will require the heating system to run constantly at full load on the coldest day that the building is designed to handle.

  • Geothermal heat pumps transfer heat between the building and the ground. Although they cost more to install, they have low operating costs. If your building is located near a body of water, such as a pond or lake, water-source heat pumps can offer similar advantages.

  • The heat pipe, originally developed by NASA to cool spacecraft, lowers an air conditioner's energy consumption by 5 – 10 percent by improving its ability to dehumidify the air.

  • Consider variable speed motors and compressors. Instead of always operating at full power, these allow heat pumps and air conditioners to more closely match energy use to temperature fluctuation.
