Try these low- or no-cost tips to boost your household’s energy efficiency:
- Insulate your attic. Homes heated by natural gas and oil should have at least six inches (R-19) and for homes heated by electricity, you should have at least 12 inches (R-36).
- Insulate and weatherstrip your attic door.
- Install a vapor barrier in your attic to reduce the flow of moisture from inside your home through the insulation. This reduces condensation that can lower insulation efficiency. When installing vapor barriers, be sure to follow the manufacturer’s instructions.
- Vent your attic appropriately. When adding insulation, you may have to add ventilation as well. As a general rule, you need one square foot of free ventilating area for each 150 square feet of attic floor area. Keep attic vents clear of debris such as insulation, tree limbs, bird nests, etc.
- Caulk or seal all cracks in masonry walls.
- Insulate basement walls, especially those portions above the ground, and the rim joist where the basement ceiling joists meet the foundation wall.
- Insulate between floor joists over unheated areas.
- Insulate crawl spaces under heated areas.
- In your workshop, use hand tools whenever possible. Maintain power tools in top operating condition.
