Home energy efficiency is a complex topic that affects our energy bills, comfort, and indoor air quality. As leaders of residential energy conservation in Northern Virginia and Metro DC, The Fifth Fuel team is dedicated to educating home and business owners about building science concepts and how these concepts influence our built environment. For example, homeowners commonly think their heating and cooling system isn’t performing properly, when in reality, a home performance issue is causing uneven home temperatures.

Our blog is designed to provide useful information that can be applied to gaining an understanding of home energy efficiency, helping our customers to make informed choices about energy-saving home improvements including insulation, air sealing, and crawlspace encapsulation.

For many Washington DC-area homeowners, dealing with temperature differentials between floors is a fact of life. Some let years go by simply assuming that they don’t have any control over this all-too-common issue, opting to install extra window AC units or multiple fans to keep parts of their home cool. The fact is, however, getting to the root of the problem is the only way to fix temperature differentials, and it doesn’t have to be quite as difficult as you might assume.

No matter what time of the year it is, you’ll be hard pressed to find a better solution to enhancing home comfort and energy efficiency than by focusing on insulation.

Cape Cod-style homes date back to 17 century New England, where these charming homes were designed to withstand the elements. The homes are compact and have a simple rectangular footprint. A steep roof helped shed snow, relatively low ceilings made it easier to heat, and shutters helped keep wind out during storms.

The revival of the Cape Cod homes began in the late 1920s and lasted for several decades. We now have many such homes throughout Northern Virginia and Metro Maryland.

Out of sight, home ductwork is often forgotten by many homeowners. Issues relating to ductwork can, however, have a major impact on home performance and efficiency.
