ensuring energy-system reliability, a strong economy, and a healthy environment. 1 This Guidebook focuses on energy efficiency in the electricity sector as opposed to the energy sector in general, although many of the EM&V approaches described can be applied more broadly. Key Terms for EE Activities EE measure: A single technology, energy-use. An air conditioner’s EER, or Energy-Efficiency Ratio, is the ratio of the cooling output in Btu’s divided by the unit’s power consumption in Watts at a specific temperature (usually 95 degrees Fahrenheit). The higher the EER, the more efficient the model.

Only turn on your computer, monitor, printer and fax machine when you need them. Setting your thermostat to a lower how to get a red wine stain out of carpet than normal will not cool your home faster.
Refrigerators and freezers actually operate most efficiently when full, so keep your refrigerator and mesure as full as possible using water bottles if nothing else.

Set your refrigerator temperature to the manufacturer's recommendation to avoid excessive cooling and wasting energy. Don't leave bathroom or kitchen ventilation fans running longer than necessary.
Bow replace inside air with outside. Replace your windows. If your home has single-pane windows, consider replacing them with more energy efficient windows, or adding solar shades or tinting film.
Install a programmable thermostat that will ,easure adjust the temperature according to your schedule. Turn off the lights when they're not in use. Don't leave your mobile phone plugged in overnight. It only takes a couple of hours to charge. Turn wfficiency the oven a few minutes before cooking time runs out.
Your food will continue to cook without using the extra electricity. Watch your appliance placement. Avoid placing appliances that give off heat, such as lamps or TVs, near a thermostat. Dress for the weather. When you're at home, dress in warm clothing in the winter and cooler clothing in the summer to stay comfortable without making your heater and AC work harder.

The Ship Energy Efficiency Management Plan (SEEMP) is an operational measure that establishes a mechanism to improve the energy efficiency of a ship in a cost-effective manner. The SEEMP also provides an approach for shipping companies to manage ship and fleet efficiency performance over time using, for example, the Energy Efficiency. Apr 20, · The Kilowatt Hour (kWh, sometimes styled as "kW h" or "kW-h", but NEVER "kW/h") measures energy. It is about how much fuel is in something or how much energy is Estimated Reading Time: 7 mins.

Is this describing the weight of the unit? If you are looking for a new heater, air conditioner or heat pump, be familiar with these acronyms. This Fact Sheet discusses the terms along with some other pertinent heating, ventilation and air conditioning HVAC topics.
This old descriptive scientific unit dates back to the mids and is still used in North America. Essentially, a Btu is the amount of heat energy required to raise the temperature of one pound of water about a pint one degree Fahrenheit in one hour.
This is also about the amount of energy given off by completely burning a wooden kitchen match. Why use a heating unit to describe an air conditioner? This is another old British scientific unit.
It comes from the amount of heat required to melt one ton of ice in 24 hours, starting at 32 F. Typical home air conditioning units are 3 tons to 7 tons in cooling capacity. Obviously the bigger the space, the more tons the unit has to be to move the heat. The better insulated a building space is, the smaller fewer tons the AC or heater needs to be.
The specifics of how a contractor should determine the correct size, or capacity, of a heater or AC unit will not be discussed here. However, itt should be based on some type of calculation of the heat moved in a particular building. Usually this is done with very specialized software that needs details of the building, usage and local climate.
Guessing is not an acceptable method of sizing HVAC equipment. Undersized equipment will not meet comfort standards and the problems are obvious.
Therefore, when people estimate HVAC equipment size they tend to overestimate. This also has problems. Oversized equipment runs repeatedly for very short periods. This does not allow humidity to be removed from the home, is hard on equipment, is less efficient and the larger equipment has higher initial costs. Once the HVAC equipment is installed at the house, it is very expensive to fix a sizing mistake. This logo can be seen on all sorts of things from computers to entire homes to air conditioners Figure 1.
The mark is part of an energy efficiency rating program developed by the U. Environmental Protection Agency and the U.
Department of Energy. While its main aim is the reduction of greenhouse gases by increased energy efficiency, it has become synonymous with energy efficiency standards for more than 70 product categories. This is the total cooling capacity of an air conditioner or heat pump in Btus during its normal annual usage, divided by the total electric input in watt-hours during the same time period.
The higher the SEER number, the more efficiently the unit is at converting electricity into cooling for the home. This is very similar to miles per gallon in cars.
Some efficient equipment can have SEER ratings of more than HVAC units in the U. For this reason, the Department of Energy keeps raising the minimum SEER number allowable for new air conditioners and heat pumps sold in the U.
As a buyer, however, even higher SEER units are available, but will initially cost more. One has to weigh the increase in initial cost versus the yearly savings to determine if it is desirable to spend more for a higher SEER unit. The SEER rating also declines as the outside temperature rises. If the unit is installed incorrectly or the ductwork is leaky and not well made, the actual overall SEER rating can be much lower as well.
This measure is for heat pumps in the heating mode. This is the total heating output of the heat pump during its normal annual usage divided by the total electric input in watt-hours during the same time period. This rating is similar to the SEER rating, but is for heating and is used only with heat pumps. And similarly, the higher the HSPF, the less the unit costs to heat a space during one year Figure 3.
Figure 3. As of January 23, the government established minimum standards for newly manufactured heat pumps at 7. Split system heat pumps that are considered high-efficiency have at least an HSPF of 8.
The consumer pays more for equipment with higher HSPF ratings and, like the AC units, it becomes a decision of initial cost versus yearly savings for new equipment. This measure is for oil or gas not electric fired heaters and boilers. The minimum allowed AFUE rating for a non-condensing typical home heater fossil-fueled, warm-air furnace is 78 percent; the minimum rating for a fossil-fueled boiler is 80 percent; and the minimum rating for a gas-fueled steam boiler is 75 percent.
Again, these systems will be more expensive and the consumer must weigh the lower fuel use against the higher initial cost see Table 1. These two measures are typically used by engineers for large systems and may not be encountered very often by consumers, but are included here for information.
The higher the EER, the more efficient the model. COP, coefficient of performance, is the measurement of how efficiently a heating or cooling system does its job. As with all the measures described here, a higher COP is more efficient and desirable than a lower one. Selecting a new heating or cooling unit is a tradeoff between several factors.
Initial cost, energy savings, type of fuel, etc. A very important consideration is the quality of system installation including the duct work for air distribution. Duct work should be insulated and sealed. Finally, HVAC units are like any other complicated machinery, they need periodic maintenance. The filters need replacing, the coils need to be cleaned on occasion, duct work inspected and thermostat checked.
Like a car, the owner must protect the investment through maintenance and periodic inspection.
