Is passive solar design feasible for mobile homes?

Adapting Passive Solar Design to Mobile Homes

Passive solar design aims to harness natural light and heat from the sun to reduce the need for mechanical heating and cooling systems. Mobile homes can be designed to incorporate passive solar principles, but their mobility and smaller size require creative solutions. For example, a south-facing skylight or large window can bring in natural light and heat during the winter months, while overhangs and awnings can provide shade during the summer.

Strategic Orientation and Overhangs

The orientation of a mobile home is crucial for passive solar design. Ideally, the mobile home should be positioned to face within 15-20 degrees of true south, allowing the sun’s rays to enter the home during the winter months. Overhangs can be used to control the amount of direct sunlight that enters the home, reducing heat gain during the summer months. For example, a 2-foot overhang can block up to 75% of direct sunlight during the summer solstice.

Using Thermal Mass and Insulation

Thermal mass materials, such as concrete or brick, can be used to absorb and store heat from the sun during the day, releasing it at night to keep the home warm. Mobile homes can incorporate thermal mass through the use of concrete floors or walls, or through the use of thermal mass blocks. Additionally, high-performance insulation can be used to minimize heat loss and maximize the benefits of passive solar design. A well-insulated mobile home with a well-designed passive solar system can reduce heating and cooling costs by up to 50%.
