There are many different ways to reduce your household’s energy use, ranging from simple behavioral adjustments to extensive home improvements. The two major motives for conserving energy are to save on utility bills and protect the environment. Here are the ten most common ways to conserve energy in your home, listed from the simplest to the most intensive methods. Continue reading
Insulation is applied to ductwork to enhance thermal performance and prevent condensation and dripping. Duct thermal performance needs enhancement since air transported through a supply duct is at a temperature different than that of the surroundings. Insulation reduces the rate of thermal loss to those surroundings. Without insulation, the air would need extra heating or cooling in order to arrive at the design supply air temperature.

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
When To Vent Your Roof and When Not To
Much information has been devoted to the subject of roof venting. So much, that it’s easy to become confused and to lose focus. So let’s start with something that might sound controversial, but really isn’t: a vented attic, where insulation is placed on an air-sealed attic floor, is one of the most under-appreciated building assemblies in all of building science. A vented attic works in hot climates, mixed climates, and cold climates. It works in the polar arctic and in humid rain forests.
Executed properly it works absolutely everywhere, in every climate. 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:
