Operational changes

• Install programmable thermostats.
• Close off rooms that are not in use and adjust the temperature in those rooms.
• Do not condition rooms that do not need to be conditioned, thereby reducing the thermal envelope.
• Use insulated shades and curtains to control heat gain and loss through windows.
• Use operable windows, shutters, awnings and vents as originally intended to control temperature and ventilation.
• Take advantage of natural light.
• Install compact fluorescent lights (CFL) and light-emitting diode (LED) lights.
• Install motion sensors and timers for lighting and local ventilation, such as bathroom exhaust fans.
• Reduce “phantom” electricity loads by turning equipment off when not in use.
• Clean and service mechanical equipment regularly.

Requires Minimal Alteration

• Reduce air leakage.
• Add attic insulation.
• Install storm windows.
• Insulate basements and crawlspaces.
• Seal and insulate ducts and pipes.
• Weather strip doors and add storm doors.
• Add awnings and shading devices where appropriate.

Requires More Alteration

• Add interior vestibules.
• Replace windows.
• Add insulation to wood-frame walls.
• Add insulation to masonry walls.
• Install cool roofs and green roofs.
