There are many energy efficiency techniques that can be applied in rehabilitation projects including installing additional insulation, reducing air leakage, and converting to high efficiency HVAC equipment and appliances. This topic will provide general guidance on how to identify the most substantial energy saving opportunities in a home.
A Closer Look at Energy Saving Techniques
The list of energy efficient techniques is varied and extensive. Energy-efficient improvements not only make homes more comfortable; they can yield long-term financial rewards. Energy bills in rehabilitation projects can be reduced by 10 to 50 percent. Most often, reduced operating costs more than make up for the higher price of energy-efficient appliances and improvements over their lifetimes.
What are some options for energy savings? Some techniques include:
- Adding insulation to the attic, walls, or foundation walls;
- Adding weather-stripping or caulking around windows and doors and caulking cracks in the building envelope;
- Installing storm windows or doors, or replacing single-pane windows with new, energy-efficient windows;
- Using passive solar designs;
- Installing high efficiency lighting and appliances;
- Installing high efficiency HVAC equipment;
- Fixing leaks in duct systems and insulating the ducts; and
- Cleaning the filters of mechanical heating and cooling systems.
By combining well-known techniques of insulation with passive solar design and upgrading to high efficiency equipment, a homeowner or homebuilder can achieve dramatic energy savings. This contributes to increased comfort levels, lower total housing costs, and less energy-related pollution of the environment. Additional information on energy saving techniques is available through the PATH program and the Department of Energy.
