Are Modular Homes Heat Efficient?

All of us have received an overly-large utility bill at some point… and it hurts! Whether it’s the dog days of summer or the bitter cold in winter, it doesn’t matter. Heat efficiency is all about reducing air leakage and preventing heat transfer. So, here is the question: Are modular homes more heat efficient than site-built homes?

If so, then that’s pretty exciting. After all, modular home prices are already 20% less than the same house built in the traditional manner. Saving money on utility costs after your home’s built just sweetens the deal even more.

Air-Tight Construction

Heat always moves towards cold (according to the Law of Thermodynamics). So, in winter, you lose heat to the outside and in summer the heat moves inside. Radiant heat from windows can reduce efficiency, but many times your high heating and cooling bills are a result of leaking air.

Because modular homes are assembled on site, the units must be built according to the strictest tolerances. If they are off even a little, then the modules won’t line up during setting. For that reason, quality control at the factory is strict. Modular construction means fewer gaps and less chance for air leakage. The result is a home that is both heat efficient and solidly built.

Efficient Heating and Cooling

Think of a modular home like a series of building blocks that are joined together to form your house. Each block, or module, has its own floor, walls, and ceiling. This means there are two walls between the joined rooms. The result is a well insulated, heat efficient house.

If you use zone heating and cooling, then you can increase heat efficiency by only conditioning the areas used. For instance, a Cape Cod floor plan usually has one and a half stories with the bedrooms being upstairs. At night you can adjust the temperature in your bedrooms separately from the rest of the home. In the morning, you reverse the process and heat or cool the living space. This is accomplished with programmable thermostats and separate heating systems for each “zone.”

Modular home additions don’t even need to tie into your central heating and cooling. For a single room, you can use another type of heating system. A ductless mini-split system can be installed for very little money and only utilized when needed. All that’s required is a three-inch hole and an electrical outlet.

Energy Star Savings

Because modular homes are customizable, you can choose to build your new home with even more green options, which save energy and often qualify for tax credits.

  • Energy Star Appliances
  • Geothermal Heating and Cooling Systems
  • High-Efficiency Windows

Look for the Energy Star designation and research which tax benefits are available to you on not only the Federal level but also state and local.

Are modular homes heat efficient?

Yes! They are well insulated, tightly built, and because they are customizable, can be built using energy efficient options. A modular home costs less to build so why wouldn’t you talk to a modular home builder about building your new home?
