Check the window's NFRC rating label. The NFRC (National Fenestration Rating Council) is an independent testing organization that rates the "U-Factor" for replacement windows. This is a measurement of the window's ability to resist the transfer of heat and cold. U-Factor is the amount of heat transferred through a material. The lower the U-Factor, the slower the rate of heat flow and the better the insulating quality.

Energy efficient windows increase the comfort level in your home by reducing cold drafts and making a house feel warmer in the winter and cooler in the summer. They help control condensation because the interior surfaces of energy-efficient windows stay warmer, allowing you to maintain a higher level of humidity without worrying about condensation on your windows.

Numerous factors, including how the frame and sashes are engineered and built, the type of glass used (single-, double- or triple-pane), the weatherstripping, the type of low-emissivity coating on the glass and the presence of argon or krypton gas.

Eye Saver is efficient because it controls light from escaping through the top of the bulb, thereby directing more light (than a standard incandescent bulb of similar wattage) onto the work surface. (back to top) Eye Saver gives off the same amount of heat as a conventional incandescent bulb of similar wattage. (back to top)

Buy one with an ENERGY STAR® Label. ENERGY STAR® Homes are designed to use at least 30 percent less energy than required by the national Model Energy Code. To achieve ENERGY STAR® status, a home must be validated by a Home Energy Rater - a certified, third party inspector who audits and tests the home. Home buyers can also save money on their mortgages. ENERGY STAR® Mortgages give home buyers easier access to preferred financing.

This is mainly about avoiding heat loss (see above), but you can add heat exchangers (with appropriate filters to prevent them getting clogged up) for added efficiency. These take a high proportion of the heat from discarded air and use it to warm the new fresh air supply. Venue operators have a duty of care to workers under Health and Safety regulations. A casino worker recently won an out-of-court settlement of around £50,000.

Many utility companies have incentives for building energy-efficient homes. Also, oftentimes money spent on energy saving heating and cooling systems result in much lower operating costs, leaving more money in the family budget for the actual cost of the home.

It is always best to be energy efficient, but if not, it is still best to use radiant because you will use less energy and spend less money. You may need a supplemental heat source on very cold days, but radiant heating is the only way to be truly comfortable in a room that is not energy efficient.

Yes; Aluminum reflects the vast majority of the sun’s rays, so it doesn’t retain as much heat as wood, asphalt shingles, tile, or cement. This means your Country Manor Shake roof will not pass the sun’s heat into your attic, reducing the load on your air conditioner in the hot summer months and possibly saving you energy dollars.

Since there is no surge involved in the starting of any residential bulb, the answer is if you are not using them, turn them off. fluorescent lamps have different operating needs. If you have a fluorescent lamp, the general rule is turning the lamp off unless you are going to need it again within fifteen minutes. Frequent cycling, turning on and off for short periods of time such as in a closet application, can reduce the life of a fluorescent lamp.

Yes. Pinnacle and Ritz-Craft is an ENERGY STAR® partner and committed to using energy efficient building methods and materials. Our homes are built standard with 2" x 6" exterior walls and R-19 insulation, R-30 blown-in ceiling insulation, warm edge thermo pane low-e glass windows, and insulated exterior doors.

The question of "turn them off or let them burn" is a common one in lighting. Since there is no surge involved in the starting of any residential bulb, the answer is "if you are not using them, turn them off." The cost of operating a light bulb is the wattage consumed while lighted thus the general answer is turn them off. High intensity discharge lamps (rarely found in indoor household applications) and fluorescent lamps have different operating needs.

Rebates for adopting energy-efficient lighting are usually offered through local and state utilities. To find out if any rebates are currently available, please check with your energy provider.

ENERGY STAR® is the government-backed symbol for energy efficiency. Products that have earned the government’s ENERGY STAR® label (such as refrigerators, freezers, and other appliances) lower greenhouse gas emissions by meeting strict energy efficiency guidelines established by U.S. Environmental Protection Agency and the U.S. Department of Energy.

Use the energy savings calculator to determine the cost savings of switching from an HID system to a fluorescent lighting system in your workspace. You will need to know the annual burning hours of the system, the energy costs in your area, your estimated labor rate, if your system will be dimmed (% of time and brightness), fixture quantity, total wattage, and lamp cost.

The Energy Efficient Mortgage allows a homebuyer to save future money on utility bills. This is done by financing the cost of adding energy-efficiency features to a new or existing home as part of an FHA-insured home purchase. The EEM can be used with both 203(b) and 203(k) loans. Basic guidelines for EEMs are as follows: The cost of improvements must be determined by a Home Energy Rating System or by an energy consultant.

Yes. The sign is designed to stay on 24 hours a day 365 days a year and will only cost you around $2 per year.

Don’t be misled by unsubstantiated claims of efficiency. Efficiency rates should be backed by test reports from independent certified labs, the approach taken by Schwank. With the same gas input, the supraSchwank luminous heater (the world’s top efficiency model) produces more than twice as much radiant heat as a standard luminous or tube heater.

Yes. At least as efficient as a timber frame and because the steel does not shrink or warp the likelihood of cracks is reduced therefore less opportunity for outside air to enter or inside air to leak out.

In practical terms this means that to boil a jug of water you will need 25 times the energy input for the the desired result (a jug of boiling water). This means that you will require 25 x 2000 kw/h = 50 000 kw/h input for the desired output in order to maintain your 2000 kw/h life style.

Appliances under the "Energy Star" are developed to be more energy efficient. These appliances may cost more to purchase but the return on energy costs(increases) does save money. The more efficient with higher energy cost speeds up the rate of return.

Our log homes are some of the most thermally efficient homes on the market today. Because of their thermal mass and the cellular structure of the wood fiber our homes are approximately 40% less expensive to heat and cool than that of a conventional frame home built with 2" x 6" walls (R-19).

an approximate rule of thumb one 2.5sq mtr flat panel collector will provide nearly 1000kWh of free energy per year. In the summer months the panels can produce temperatures of well over 100 degrees C, depending on circulation flow rates

A premise behind the design philosophy of BuildingCircles is that basic shelter should contribute toward its own internal heating and cooling. It should be supported by annual solar heat storage and other alternative, non-carbon dioxide producing energy systems. Relatively large amounts of thermal energy can be derived from daily solar gain and stored seasonally in the ground for interior and hot water heating.

Unlike regular wood framed structures, log homes are rated in “Thermal Mass” as opposed to “R” values. The “Thermal Mass Effect” relates to the ability in which heat transfers through the walls of a building is delayed by the wall mass. Log homes may be expected to perform from 2.5% to over 15% more energy efficiently compared to an identical wood-framed constructed home, considering annual purchased heating and cooling energy needs.

Yes! personal_space can be built to be as efficient (or far more energy efficient) than a typical "house." We are very meticulous about insulating and sealing the shell of each p_s, so that it uses very little electricity or other energy source to keep warm or cool. With rising energy costs seeming to be a way of life, we think it's both a conservative and plain smart way to go. A small personal_space could conceivably cost as little as $15-20 a month to heat during cold weather.

Yes! Fluorescent lighting (globes and/or tubes) can be relatively expensive to buy. They will, however, last much longer than ordinary incandescent globes, with a significantly reduced energy consumption. They're great for areas where the light is on for long periods - like kitchens, family rooms and hallways or for outside night security lighting.

quot;energy efficient" motor produces the same shaft output power (hp), but uses less input power (kW) than a standard-efficiency motor. Energy efficient motors must have nominal full-load efficiencies that meet or exceed the NEMA threshold standards. Many motor manufacturers produce models significantly exceeding the NEMA standard.
