We Cut Heating Costs in Vermont Homes Everyday
Building Energy puts a stop to drafts from chilling you in the winter and will get you incentives from Efficiency Vermont for doing it! Air sealing and insulating the “envelope” or “shell” of your home – its outer walls, ceiling, windows, doors, and floors – is often the most cost effective way to improve energy efficiency and comfort.
ENERGY STAR estimates that a knowledgeable homeowner or skilled contractor can save up to 20% on heating and cooling costs (or up to 10% on their total annual energy bill) by sealing and insulating.
The first step in making your home more comfortable and reducing your building’s carbon footprint is determining where the leaks are!
How we do it:
Many air leaks and drafts are easy to find because they are easy to feel – like those around windows and doors. But holes hidden in attics, basements, and crawlspaces are usually bigger problems. Sealing these leaks with caulk, spray foam, or weather stripping will have a great impact on improving your comfort and reducing utility bills.
Homeowners are often concerned about sealing their house too tightly. This is very unlikely in most older homes. A certain amount of fresh air is needed for good indoor air quality and there are specifications that set the minimum amount of fresh air needed for a house. Diagnostic tools to measure your home’s actual air leakage can be used to determine whether or not there is proper air flow. If your home is too tight, a fresh air ventilation system may be recommended.
Most structures have air leaks that allow heat out and cold air to flow in. To fix these leaks, we pressurize a structure using a blower door. We are then able to use smoke sticks or a fogging device to identify and seal the leaks. This is a particularly critical step in structures insulated with fiberglass.
