1) Need for energy audit
2) Energy audit instruments
3) Anemometers
Anemometers are essentially fluid flow measuring instruments.As energy audit tools, they are most commonly used to measure air flow from heating, ventilation, and air conditioning (HVAC) systems.
4) Ultrasonic flow meters
They are used to estimate fluid flow without having to penetrate piping.They use frequency shift experienced by an ultrasonic signal as it is reflected by bubbles or particles (i.e., discontinuities) entrained by a flowing fluid. The magnitude of the frequency shift is indicative of the velocity of the fluid.
5) Hygrometers
A hygrometer is an instrument used for measuring the moisture content in the atmosphere.They use sensors which react to varying levels of humidity by causing a physical change in a material which changes its electrical properties (often resistance).The materials’ electrical property is calibrated to humidity
6) light meters
Light meters measure illumination or light level in units of foot-candles or lumens. Light emitted by the area of interest passes through a light-sensitive layer of cells contained in the meter.This light is converted to an electrical signal proportional to the lights’ intensity.
7) Multi-meter
They measure amps (electron flow), volts (electrical pressure) and ohms (resistance) of electrical equipment.Multi-meters, particularly the digital clamp-on designs, are considered the most versatile audit instrument.The typical multi-meter will measure 0 to 300 amps, 0 to 600 volts, and 0 to 1,000 ohms.
8) Ph meter
The pH of an aqueous solution is a value expressing the solutions’ acidity or basicity, based on the concentration of hydrogen ions present (where 0 is strongly basic, 14 is strongly acidic, and 7 is neutral).
9) Power factor meter
Power factor meters are used to measure the power factor of electrical equipment, particularly three-phase motors.Power factor is a measurement of the electrical current in a wire which is doing useful work compared to the total electrical current in the wire.
10) Non contact Infrared thermometer
These thermometers rely on the electromagnetic radiation emitted by solids or fluids. The radiation is characteristic of their temperature.
The heart of the infrared thermometer is the detecting surface, which absorbs infrared energy and converts it to an electrical voltage or current.
11) Non contact Tachometer
A tachometer is an instrument used to measure the rotational speed of a shaft or wheel in revolutions per minute (rpm).Non-Contact tachometer employs a variable-frequency, flashing light which makes the rotating component appear to stand still when the frequencies match.

1) Need for energy audit
An energy audit is an Inspection, Survey and 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.
An energy audit can help determine
a.the energy-wasting
deficiencies and
b.can show exactly
how to address those problems
1)Even more useful,
an energy audit will tell
