Since the ceiling, wall and floor cavities for many manufactured homes are sealed, it is difficult to add insulation. However, some models have attic spaces in which you can install extra insulation and some insulation companies can blow insulation into the floor cavity.
In new homes, look for a minimum R-value of R-11 for walls, R-19 for floors, and R-30 for ceilings.
Make sure insulation has not shifted during transit before joining multi-section homes.
See that the “marriage walls” are airtight with foam gaskets installed between sections.
Seal all plumbing and wiring penetrations using expanding foam or caulk.
If your home has an old or inefficient heating and cooling system, consider replacing it with a new ENERGY STAR® unit. Make sure it is properly sized for your home.
Upgrading an electric resistance furnace to a high-efficiency heat pump will dramatically lower your annual heating costs.
Change return air filters monthly.
Have your system tuned up annually to maintain maximum efficiency.
When possible, strategically position your home or plant trees to protect it from unwanted summer sun and act as a windbreak in winter.
Exterior solar shade screens can effectively shade east and west windows and enhance privacy.
While shading windows on the outside is most effective, using light-colored shades or blinds to reflect sunlight back through the glass will also help reduce air conditioning costs.
Make sure your dealer grades the site properly. Poor grading can lead to settling and moisture problems.
Have the long sides of your home face north and south and the short sides east and west to take advantage of the sun’s heat in winter and provide the greatest protection from the summer sun.
Thanks to exciting developments in energy efficiency, a manufactured home can be an energy-efficient home — saving you money and increasing your home’s comfort, safety and durability. Like traditional site-built homes, many new manufactured homes are designed to be energy-efficient and use renewable energy systems. But even older homes may be remodeled or retrofitted for both.
Most manufacturers offer energy efficiency options for new homes. While they may add to the purchase price, they can save thousands of dollars over the life of your home and greatly increase its comfort and value. Specifying a high-efficiency heat pump rather than natural gas, propane or electric resistance units will assure lower heating and cooling operational costs.
Always choose Energy Star products including appliances, HVAC systems and lighting. Set the water heater to 120 degrees. Make sure the clothes dryer is vented to the outdoors and away from heating and air conditioning components.
