Energy Efficiency Through Due Diligence
Performing a home energy audit is the first step to saving money on utility bills
By Mike Federman, contributing writer for Ruralite Services
Homeowners can avoid the chill of winter by making their homes more energy efficient.
The first step to lowering your utility bill is to do a home energy audit. An audit will help locate areas of energy loss that cost you money. You can conduct the energy audit yourself or seek the help of a professional. Some co-ops provide this service to their members.
Below are some tips recommended by the U.S. Department of Energy:
To get a more detailed evaluation of your home, you can hire a professional energy auditor. Some professional auditors do a blower door test, where a large fan is mounted in the frame of an exterior door to draw out air from the house. The auditor uses the test to determine the air infiltration rate inside your home. A calibrated test is recommended because it not only locates air leaks, but measures the amount of air pulled out.
Good Balance Required
When upgrading your home, it is critical to balance weatherization with proper ventilation. You want to control air infiltration but also provide adequate air exchanges and ventilation for good indoor air quality and moisture control. All ventilation equipment such as range hoods, vent fans and dryers should have back draft dampers installed in the duct system and be vented to the exterior. All kitchen range hoods and bath fans must be vented through the roof or sidewall to the outside. Clothes dryers should not use vents that can be vented to the interior. The additional moisture introduced into the home can be excessive.
In a tightly built energy-efficient home a heat-recovery ventilator (HRV) may be necessary. It will exhaust stale air, but recover most of the BTUs to pre-warm or pre-cool incoming fresh air. The HRV can also help control excess moisture, and expel radon gas and odors.
