Computers alone are believed to account for 5 percent of commercial electricity consumption. The selection of energy efficient products can, then, help reduce a facility's energy consumption. Heating and Cooling . Shutting down HVAC systems for non-critical uses for short periods can result in significant savings. Insulation Concerns .
Insufficient insulation can result in the loss of large amounts of energy.
For example, the poor insulation of windows is responsible for approximately 25 percent of all heating and cooling requirements. The insulation of heat-generating equipment also reduces the need for building cooling. Proper weather stripping reduces energy losses, as do revolving and double doors. Such windows employ a gas, such as argon, between two coated panes of glass to minimize energy losses. Hot Water .
