Warehouse cooling


  • Make sure your commercial business is properly insulated. This is the single most important step in conserving energy. Thermal insulation should be specified in terms of thermal resistance (R-values). R-30 (10″) is recommended for ceilings, and R-11 (3-1/2”) for exterior walls and floors over unheated areas. In colder climates, consider additional insulation.
  • Infiltration of humid outside air is your heating and air conditioning system’s worst enemy—it could account for 15% to 30% of air conditioning energy requirements. Find the places where air can sneak into the building and plug them with caulking, weather-stripping or plastic. Also, weather-strip and caulk around all entrance doors and windows.
    Cut heat transfer through your windows by 40% to 50% with double-glazing (two panes of glass separated by a sealed air space) and low-e glass.
  • Use wood- or metal-frame storm windows even if single-glazed windows are high quality. The extra layer of glass and the layer of still air will cut heat transfer considerably.
    Install storm doors at all entrances to your house.
  • Keep all windows and doors closed.
  • Remember that by increasing the glass area, you increase the amount of heat added in summer and lost in winter.
    Make sure fireplaces have tight-fitting dampers, which can be closed when the fireplace is not in use. Invest in a humidifier to conserve energy in winter. The air in your home won’t be as dry, so you stay comfortable at a lower temperature setting.
