Manufactured homes can also be designed for renewable energy and energy efficiency just like conventional site-built homes. If you are a manufactured homeowner, then you have the luxury to retrofit and remodel your old manufactured home to add renewable energy equipment and for improving the energy efficiency.
You might be aware of the fact that manufactured homes are factory-built structures, which are transported to a building site for installation. However, it is significant to note that there are plenty of differences between manufactured homes, which were built before the introduction of U.S. Department of Housing and Urban Development (HUD) Code in 1976, and the ones that were built afterward.
If you happen to be an owner of a pre-1976 manufactured (mobile) home, then here are a few energy efficiency improvement techniques that will help you to considerably reduce the heat loss of your home.
- Install energy efficient doors and windows;
- Add an insulation to the belly of the structure;
- Perform general repairs on ducts, caulking, and on other parts of the manufactured home;
- Add proper insulation to the walls;
- Install belly traps;
- Install insulated skirting; and
- Add roof cap or simply add insulation to your roof.
The NREL (National Renewable Energy Laboratory) conducted a series of experiments from 1988 to 1991 on pre-1976 manufactured home. The results obtained during the experiments revealed that the above-mentioned retrofit measures resulted in an impressive 31 percent reduction in the usage of heating fuel.
The common methods used by manufactured homebuilders and repair technicians to include insulation to the existing cavity of their house are as follows.
- Tube blowing and drilling from the interior of the home.
- Tube blowing and drilling from the upper side of the manufactured home.
- Rolling back the roof of the home and blowing into the open cavity.
However, some homebuilders also prefer to insulate the existing cavity by using roof caps rather than filling the existing cavity of the home.
If you are looking for some more other techniques to improve the energy efficiency of your manufactured home, then take a look at these viable options:
- Weather-stripping and caulking the doors and windows instead of replacing them with energy efficient alternatives.
- Air sealing the openings around ducts and plumbing fixtures.
- Using energy efficient appliances and lighting.
