Energy Efficiency & Sustainability in Prefab Homes

Prefab Home in Portland, OR

One of the primary advantages of purchasing a prefabricated home is that they are more eco-friendly, energy efficient, and sustainable than the majority of traditionally constructed homes. There are many reasons why prefab houses are better for both the environment and your energy bills. Here at Stillwater Dwellings, our commitment to helping the environment has a huge impact on the way we build our homes. Here are some of the ways that prefab homes are built to be better for the planet.


First of all, prefab homes are much better insulated than homes built with traditional on-site construction. Building some or all of a home within a factory means that insulation can be installed more easily and more efficiently. Better insulation goes a long way in improving energy usage. Joints are tighter and air infiltration and escape are both minimized. You’ll see the great insulation of a prefab home reflected in much lower energy bills.

Less Waste 

Prefabricated homes also generate less waste during construction, which is helpful for the environment. For homes built using traditional construction, having leftover materials is inevitable. In fact, from a contractor’s point of view this makes sense, because having to re-order a material holds up construction. However, this extra waste is bad for the environment.

Prefab home builders – including Stillwater Dwellings – have eliminated the construction waste problem.  Stillwater is proud to say that we reduce waste by 50% in our construction process. Because we have fine-tuned our process to minimize waste, the overall cost of construction goes down. Once again, efficiency helps both you and environment!

Fixtures & Materials

Custom prefab homes are usually constructed with materials and fixtures that are earth-friendly and energy-conscious. Prefabricated homes pioneered the movement toward using sustainable materials in the home, such as bamboo and cork. In addition to sustainable resources, prefab home builders use recycled and recyclable materials. You can even get insulation crafted from recycled materials. A prefabricated home often comes with paint, wallpaper, and finishes that have low or no VOCs. VOCs – AKA volatile organic compounds – are frowned upon in the world of home building because not only are they bad for the environment, they are also harmful to respiratory health.

The fixtures in prefab homes are also installed with the environment in mind. Toilets, sinks, and showers are usually low-flow in prefabricated houses.  You can choose to have in-floor radiant heating installed in your custom prefab house, too. These heating systems slash energy bills, and without vents you don’t have to worry about allergens and dust circulating around your home. At Stillwater, our custom prefab homes are built to maximize natural light, as well, so you don’t have to waste more energy and money on electricity.

By being more efficient and eco-friendly, prefab homes are better for the environment and for your wallet. Our homes are designed to make a smaller impact on the earth and a larger (positive!) impact on your energy bills.
