an indoor cabinet that contains the evaporator coil.an outdoor metal cabinet that contains the condenser and compressor.The majority of consumers have split systems in their homes.Ī split-system central air conditioner has 3 components: SHGC ranges from 0 to 1.Ī central air conditioner (or heat pump) is either a split-system unit or a packaged unit. The lower the SHGC, the lower the heat gain through a window. Measures how well a window blocks heat from sunlight. A higher SEER can result in lower energy costs.
The higher the SEER rating, the more energy efficient the equipment is. Taxpayers must keep a copy of the certification statement for their records, but do not have to submit a copy with their tax return. The IRS encourages manufacturers to provide these Certifications on their website to facilitate identification of qualified products. Is a signed statement from the manufacturer certifying that the product or component qualifies for the tax credit.
BEEN SEER HOMEPAGE BUILDER CODE
Standards published by the International Code Council, the IECC sets forth compliance methods for energy-efficient construction of both residential and nonresidential construction. New units in the US have HSPF ratings from 7.0 to 9.4. As the HSPF increases, the unit functions at a more efficient level. Rates the efficient operation of the heating portion of the heat pump. HSPF (Heating Seasonal Performance Factor) For clothes dryers, the energy factor is defined as the number of pounds of clothes dried per kWh of power consumed. For clothes washers, the energy factor is defined as the cubic foot capacity per kWh of input power per cycle. For dishwashers, the energy factor is defined as the number of cycles per kWh of input power. For water heaters, the energy factor is based on three factors: 1) the recovery efficiency, or how efficiently the heat from the energy source is transferred to the water 2) stand-by losses, or the percentage of heat lost per hour from the stored water compared to the content of the water: and 3) cycling losses. Is the measure of overall efficiency for a variety of appliances.
BEEN SEER HOMEPAGE BUILDER HOW TO
This DOE site can show how to calculate potential energy cost savings of a more efficient unit. The higher the EER rating, the more energy efficient the equipment is. Of a heat pump is the ratio of the change in heat at the "output" (the heat reservoir of interest) to the supplied work. A higher rating indicates more efficient equipment. It is the amount of heating your equipment delivers for every dollar spent on fuel. Is a rating that denotes the efficiency of gas heating equipment. AFUE (Annual Fuel Utilization Efficiency) ENERGY STAR distinguishes energy efficient products which, although they may cost more to purchase than standard models, will pay you back in lower energy bills within a reasonable amount of time, without a tax credit. Please note, not all ENERGY STAR certified products qualify for a tax credit.
