TOP 5 ENERGY STAR RATED DOORS

Share it now!

According to Energy Star, a top rated program that aims at protecting the environment through greater energy efficiency, a door is clearly defined as a sliding or swinging system designed for entry and exit and installed in a vertical wall separating conditioned and unconditioned space in a residential building.  Energy star is an avid campaigner of energy efficient doors.

WHY ENERGY EFFICIENT DOORS?

Energy efficient doors have been proven to reduce energy consumption in any household by a smashing twelve percent; energy efficient doors help in the reduction of cold drafts as well as significantly reduce noise from outside the household.

CATEGORIES OF DOORS RECOGNIZED BY ENERGY STAR:

a.) the opaque door- the opaque door refers to a door with no glazing

ii)  ≤ ½-lite: A door with ≤ 29.8 percent glazing

.iii) > ½-lite: A door with > 29.8 percent glazing

CHARACTERISTICS OF TOP ENERGY STAR RATED DOORS:

U-Factor:

Energy Star rated doors have lower U-Factor for better insulation. The heat transfer per time per area and per degree of temperature difference

According to Energy Star policy, the lower the U-Factor, the more insulated a door is. The requirements insist that the U-Factor of energy efficient doors to be 0.3 or even less.

The lower the number, the better an insulator the window or door is. Low U-Factor numbers also mean that heat escape during winter season is minimal which is quite important in keeping a household warm during the colder season as well reducing heating costs..

Solar Heat Gain Coefficient (SHGC)

Solar Heat Gain Coefficient is a term used to refer to the ratio of the solar heat gain entering the space through the fenestration product to the incident solar radiation.

SGHC values typically range from 0.25 to 0.80. Solar Heat Gain Coefficient is an important factor put into consideration by Energy Star, the lower the solar heat gain coefficient is the less solar radiation the doors allow into the household. For hotter climatic conditions, home owners should choose doors with lower solar heat gain coefficient.  In cooler regions, pick out a higher SHGC.

Visible Transmittance (VT)

Visible transmittance is mainly for windows; however it also applies to doors with windows. Visible transmittance is a term used to refer to the amount of light that passes through a door. Visible transmittance is measured on a scale of 0 to 1.  The lower the visible transmittance, directly translates to a less lighted up room and vice versa.  Visible transmittance generally has no Tax credit qualification requirement.

Condensation Resistance

Energy star rated doors have high condensation resistance to prevent moisture build up

Condensation resistance, just as the name suggests, refers to the ability of a door to resist moisture build up. Condensation resistance ranges from I to 100. In lay mans language, the lower the condensation resistance the more moisture the door allows to build up. Condensation resistance has no tax credit qualification requirement. Moisture build up is quite dangerous for doors as it leads to faster deterioration of the quality of the door example causing mold and discoloration if the door is made of wood.
