Residential Windows, Doors and Skylights

Current Specification Effective Date: January 1, 2015

  • The current criteria were finalized in January 2014.
  • New performance levels (PDF, 238.86 KB) are effective as of January 1, 2016 for windows, doors, and skylights in all climate zones.
  • Windows, doors and skylights must meet U-Factor and, where applicable, Solar Heat Gain Coefficient (SHGC) requirements based on climate zone. In addition, doors must meet U-Factor and, where applicable, SHGC requirements based on glazing level (amount of glass).
  • Windows, doors and skylights originally qualified for the ENERGY STAR label in March, 1998.

What should I look for when buying windows, doors skylights?

Every ENERGY STAR window, door and skylight is independently certified and verified to perform at levels that meet or exceed energy efficiency guidelines set by the U.S. EPA. But how do you know which windows work in your climate? The following tips will help you buy with confidence.

Purchasing Tips

Shopping for new windows, doors, and skylights can be a confusing process. ENERGY STAR makes it simple! Follow these five tips to ensure your windows, doors, and skylights deliver savings and comfort you’ll enjoy.

Look for the ENERGY STAR label for your climate zone. All ENERGY STAR certified products must display the ENERGY STAR label. Check the label to make sure the product you are considering is certified to meet the criteria for your area. The ENERGY STAR label appears on the product next to the National Fenestration Rating Council (NFRC) label:

ENERGY STAR Qualified
in Highlighted Regions

Official ENERGY STAR label (and NFRC Label) for a window qualifying in the Northern and North-Central climate zones.

ENERGY STAR Qualified
in All 50 States

Ask for ENERGY STAR when ordering. When you’re ordering in a showroom, make sure to ask for a product that is certified to meet the ENERGY STAR criteria for your climate zone. You can choose ENERGY STAR certified windows in a variety of framing materials to suit your needs.

  • Get a deal. In addition to the long-term energy savings you’ll enjoy, you may be able to take advantage of financial incentives that lower your initial investment:
    • Many utilities provide financial incentives for purchasing ENERGY STAR certified windows, doors and skylights. Look for local rebates and other promotions in your area .
    • Claim federal tax credits for installing ENERGY STAR certified windows, doors or skylights or making certain other energy efficiency improvements to your home.
    • Keep in mind that the cost of complete window replacement can vary. Be sure to get quotes from several installers. Different dealers may quote difference prices for the same product. When interviewing contractors, ask them to break down the price quote by labor and materials. ENERGY STAR certified windows, doors and skylights may cost more than non-certified products, but the labor involved should be comparable for both.
    • If your house is older than 1978, be sure to look for contractors who are certified to handle lead paint .

    Review Article Clues to the functions of mammalian sleep

    Jerome M. Siegel 1

    Abstract

    The functions of mammalian sleep remain unclear. Most theories suggest a role for non-rapid eye movement (NREM) sleep in energy conservation and in nervous system recuperation. Theories of REM sleep have suggested a role for this state in periodic brain activation during sleep, in localized recuperative processes and in emotional regulation. Across mammals, the amount and nature of sleep are correlated with age, body size and ecological variables, such as whether the animals live in a terrestrial or an aquatic environment, their diet and the safety of their sleeping site. Sleep may be an efficient time for the completion of a number of functions, but variations in sleep expression indicate that these functions may differ across species.

    Vehicle Air Conditioning System Benefits:

    An Efficient vehicle air conditioning system will reduce high cabin temperature by cooling effect if heater blower fan vent system is set to recirculation mode. If the evaporator fan (blower fan for cabin) is producing warm air from vents then the air conditioning system is likely to need service maintenance.

    Enhance driver and passenger safety by maintaining a comfortable cabin temperature in hot working conditions to reduce risk of heat exhaustion. Cabin compartment air is chilled by heat transfer to produce a cooler climate for more comfortable fresh environment

    Cab Temperature control Improves working environment for operators of mobile plant increasing comfort and reducing fatigue.

    Maintain vision by keeping the windscreen demisted. Some systems can reverse the flow of refrigerant to provide heating as well as cooling.

    Filtration of air entering the passenger compartment cab reducing dusts and pollution

    Dehumidifying – Drying of the air circulating in the passenger compartment

    Enhancement of vehicle security allowing windows to remain closed in hot weather

    Strict Legislation applies to the servicing of Vehicle Mobile Air Conditioning Systems. See(MAC directive) of EC F-Gas (Fluorinated Gas) Regulations also see http://www.defra.gov.uk/environment/air-atmos/fgas/sectors/mobileaircon.htm for more details.

    Persons handling refrigerant must be F-gas trained and qualified as a refrigerant handler to meet the requirements of 2014 EC regulations and also company registered see Guidance notes

    more information about F Gas regulations and guidance is available from Gluckman Consulting see IS6 and IS22

    Commercial vehicle transport refrigeration systems may use alternative refrigerants.

    Different refrigerant types and systems require different service equipment.

    Moisture and the Air conditioning system

    Moisture is a main enemy of the air conditioning system components because;

  • Moisture can form ice and cause refrigerant circuit components to block.
  • Moisture within the refrigerant circuit can mix with oil to form acids which corrode the air conditioner system components.
  • Moisture accumulating on the surface of the evaporator and within air vents can breed bacteria causing smells inside the vehicle ( aka Sick car syndrome)

    Moisture can enter the refrigerant system if a leak occurs allowing air ingress or if the system has been opened.

    Marginal refrigerant gas loss can occur over time. The only effective cure for a refrigerant leak is a repair or component renewal.
