Energy Renovations
The person performing your assessment should leave you with a prioritized list of energy renovations. The most common areas found in residences that require work are below. NCEP maintains its own highly trained crews to perform many of the common issues that arise from an energy audit. Supervision is always provided to help ensure quality work and safety. For more complicated issues like solar water heating and higher-end foam insulation installation, we pull known resources from our cooperative base that operate under our terms of thorough, quality work with complete customer satisfaction
These leaks can make your home uncomfortable, waste energy, and cost you money.
Different types of products can be used for different types of air leaks:
•Caulk, spray foam, and weather stripping for
sealing smaller leaks
•Plywood, drywall, or rigid foam insulation for covering larger holes
•Sheet metal and high-
temperature fire caulk to seal
gaps around chimneys & furnaces
Insulation performance is measured by R-value—its ability to resist heat flow. Higher R-values mean more insulating power. Different R-values are recommended for walls, attics, basements and crawl spaces, depending on your area of the country.
Insulation is most effective air is not moving through or around it, it is important to seal air leaks before installing insulation to ensure that you get the best performance possible. When working with fiberglass you should always were a long-sleeve shirt, gloves, a face mask and goggles.
1.Install 6-10 mil polyethylene vapor diffusion barrier across the crawl space floor to prevent soil moisture from migrating into the crawl space. Overlap and tape all seams by 12 inches. Seal the polyethylene 6 inches up the crawl space walls. Use rocks to help stabilize and secure the plastic.
2.Keep the drainage plane free from debris and the drain clog free.
3.Seal the penetrations between the crawl space and the first floor.
4.Keep crawl space clean and free of all materials. Do not store lawnmowers, gasoline, hoses, wood, etc. in the crawl space. These items can contribute to poor indoor air quality.
5.Re-position fallen insulation so that it comes in contact with the above sub-floor. Secure with hooks.
6.Insulated or closed/sealed crawl spaces require insulation and conditioning.
Summary- Improving the energy efficiency of a home is a matter of addressing many of the different system’s issues. Almost any home can realize energy efficiency, water efficiency, more comfort, a higher level of health and lower carbon emissions. The following is the minimum list of items that may need to be completed to achieve a quality home:
1.Air and duct sealing
2.Insulation distribution in attic and insulation over hatch
3.Programmable thermostats, possibly with controls over usage
4.Weather stripping on front and back doors
5.Crawl space cleaning and poly- 6 – 10ml
6.Window and door seating and caulking where needed, etc.
7.HVAC review for condition and sizing
8.Water fixture replacement
