Ducts, Furnaces, & Air Handlers Belong Within Conditioned Space
Ducts, furnaces, and air handlers belong inside a house’s conditioned space. The best locations for ducts are insulated basements, sealed crawlspaces, or unvented conditioned attics. If placing ducts in these locations won’t work, they can also be installed in open-web floor trusses (in a two-story house with a centrally located mechanical room) or in some type of soffit, dropped ceiling, or chase.

A whole-house fan is an attic-mounted fan that exhausts air from a home at night, when the heat of the day has passed and the outdoor temperature has dropped enough to feel comfortable. The main advantage of using a whole-house fan instead of an air conditioner is to save energy. A whole-house fan usually draws between 200w and 700w, in contrast to a central air conditioner, which draws 2000w to 5000w. Continue reading
Windows come in a number of different frame and glazing types. By combining an energy-efficient frame choice with a glazing type tailored to your climate and application, you can customize each of your home’s windows.
Types of Window Frames
Improving the thermal resistance of the frame can contribute to a window’s overall energy efficiency, particularly its U-factor. Continue reading
There are plenty of excellent insulation materials on the market today. Many of these have been around for quite some time. Each of these insulations have their own ups and downs. As a result, when deciding which insulation material you should use, you should be sure to be aware of which material would work the best in your situation. Considering differences like R-value, price, environmental impact, flammability, sound insulation and other factors, here are the 5 most common types of insulation materials:

Every three years, the California Energy Commission (CEC) revisits its energy efficiency standards, augmenting the building code to align with recent technological advancements and the state’s new efficiency goals. The commission underwent this process again this year, identifying areas for improvement in both new construction and retrofits for residential and nonresidential properties.
With this most recent set of revisions, the commission is striving toward a pair of new state efficiency targets: achieving net zero energy for new residential construction by 2020 and for new commercial construction by 2030. Referred to as the 2016 version, these standards will go into effect January 1, 2017. Continue reading
There are many reasons to control the amount of sunlight admitted into a building. In warm, sunny climates excess solar gain will result in overheating, in cold and temperate climates winter sun entering south-facing windows can contribute to passive solar heating, and in any event controlling and diffusing natural illumination will improve daylighting.
