Teacher January 31, We use Quizlet in our classes to introduce, study, and reinforce vocabulary. It is unquestionably a better method of studying vocabulary than the traditional method of looking up a word and writing the definition. Students are saturated in the learning process with a variety of methods of learning — spelling, gaming, auditory lessons.
Principle[ edit ] When the object of study is an occupied building then reducing energy consumption while maintaining or improving human comfort, health and safety are of primary concern. Beyond simply identifying the sources of energy use, an energy audit seeks to prioritize the energy uses according to the greatest to least cost effective opportunities for energy savings.
Home energy audit[ edit ] A home energy audit is a service where the energy efficiency of a house is evaluated by a person using professional equipment such as blower doors and infrared cameraswith the aim to suggest the best ways to improve energy efficiency in heating and cooling the house.
An energy audit of a home may involve recording various characteristics of the building envelope including the walls, ceilings, floors, doors, windows, and skylights. For each of these components the area and resistance to heat flow R-value is measured or estimated.
The leakage rate or infiltration of air through the building envelope is of concern, both of which are strongly affected by window construction and quality of door seals such as weatherstripping. The goal of this exercise is to quantify the building's overall thermal performance.
The audit may also assess the efficiencyphysical condition, and programming of mechanical systems such as the heating, ventilation, air conditioning equipment, and thermostat. A home energy audit may include a written report estimating energy use given local climate criteria, thermostat settings, roof overhang, and solar orientation.
This could show energy use for a given time period, say a year, and the impact of any suggested improvements per year.
The accuracy of energy estimates are greatly improved when the homeowner's billing history is available showing the quantities of electricity, natural gas, fuel oil, or other energy sources consumed over a one or two-year period.
Some of the greatest effects on energy use are user behavior, climate, and age of the home. An energy audit may therefore include an interview of the homeowners to understand their patterns of use over time.
The energy billing history from the local utility company can be calibrated using heating degree day and cooling degree day data obtained from recent, local weather data in combination with the thermal energy model of the building.
Advances in computer-based thermal modeling can take into account many variables affecting energy use.
A home energy audit is often used to identify cost effective ways to improve the comfort and efficiency of buildings.
In addition, homes may qualify for energy efficiency grants from central government. Recently, the improvement of smartphone technology has enabled homeowners to perform relatively sophisticated energy audits of their own homes.
This technique has been identified as a method to accelerate energy efficiency improvements. Public utility companies, or their energy conservation department.
Independent, private-sector companies such as energy services company, insulation contractor, or air sealing specialist. US State energy office. Utility companies may provide this service, as well as loans and other incentives to insulate. They also often provide incentives to switch, for example, if you are an oil customer considering switching to natural gas.
Where to look for insulation recommendations: Local or state building codes. US Department of Energy. A simple do-it-yourself home energy audit can be performed without using any specialized tools. With an attentive and planned assessment, a homeowner can spot many problems that cause energy losses and make decisions about possible energy efficiency upgrades.
During a home energy audit it is important to have a checklist  of areas that were inspected as well as problems identified. Once the audit is completed, a plan for suggested actions needs to be developed.
Because Local Law 87 requires a licensed Professional Engineer to oversee the work, choosing a well-established engineering firm is the safest route. By the end ofLCEC has financed and supervised more than audits. LCEC launched an energy audit program to assist Lebanese energy consuming tertiary and public buildings and industrial plants in the management of their energy through this program.
The long-term objective of LCEC is to create a market for ESCOs, whereby any beneficiary can contact directly a specialized ESCO to conduct an energy audit, implement energy conservation measures and monitor energy saving program according to a standardized energy performance contract.
Currently, LCEC is helping in the funding of the energy audit study and thus is linking both the beneficiary and the energy audit firm. LCEC also targets the creation of a special fund used for the implementation of the energy conservation measures resulting from the study.
Industrial energy audits[ edit ] Increasingly in the last several decades, industrial energy audits have exploded as the demand to lower increasingly expensive energy costs and move towards a sustainable future have made energy audits greatly important.An energy audit is an inspection survey an analysis of energy flows, for energy conservation in a building, process or system to reduce the amount of energy input into the system without negatively affecting the output(s).
In commercial and industrial real estate, an energy audit is the first step in identifying opportunities to reduce energy expense and carbon footprints. audit projects, including the use of appropriate analytic software tools and development and maintenance of data analysis techniques and expertise within the audit team.
