Energy Audit Instruments Electrical Measuring Instruments: These are instruments for measuring major electrical parameters such as kVA, kW, PF, Hertz, kvar, Amps and Volts. In addition some of these instruments also measure harmonics. These instruments are applied on-line i.e on running motors without any need to stop the motor.

What to expect in a home energy audit?
The technician will take inventory, report on the current conditions in your home and will test for:
- Health and safety check (carbon monoxide levels, moisture, and indoor air quality problems)
- Overall comfort level (cold/hot spots, indoor air quality stuffiness/stale odors)
- Air sealing opportunities
- Insulation levels
- Heating system efficiency
- Cooling system/central air conditioning efficiency, if applicable
- Domestic hot water system efficiency
What are different types of energy audit?
There can be three types of energy audits [24], and they are walk-through energy audits, target energy audits, and detailed energy audits.
What are the three levels of energy audit?
What are the Three ASHRAE Energy Audit StandardsASHRAE Energy Audit Level 1 – the walk-through analysis. ... Energy Audit Level 2 – the detailed energy analysis. ... Energy Audit Level 3 – analysis of capital-intensive modifications.
What is energy audit system?
An energy audit can be defined as an inspection or survey analysis of energy flows in a structure, in a process or in a system, intended to reduce the amount of energy input without negatively affecting the outputs [7]. From: Comprehensive Energy Systems, 2018.
How energy audit is done?
A registered energy auditor will come to your home or business and conduct a walk-through of the inside and outside to determine your energy usage and problem areas. While conducting their walk-through, they will analyze specific elements that contribute to your home's or business's overall energy efficiency.
How many stages are there in energy audit?
Detailed energy auditing is carried out in three phases: Phase I, II and III. Industry-to-industry, the methodology of Energy Audits needs to be flexible. A comprehensive ten-step methodology for conduct of Energy Audit at field level is pre- sented below.
What are the four steps of an energy audit?
A systematic energy audit can be broken into four phases: planning, investigating, implementing and sustaining. Proactive facilities strive to continually improve energy efficiency by repeating these phases at regular intervals. This two-part column will highlight each of the four phases.
Why energy audit is required?
Energy Audit needs to be done to Identify Energy saving Opportunities in a facility or areas with excess use of Energy compared with set up standards. Energy audit is a effective tool of energy management to use Energy Effectively and Efficiently.
What is the main aim of an energy audit?
The objective of an energy audit is to save energy by maintaining and improve human comfort and health. Energy audit creates opportunities to reduce the cost of energy by simply identifying the alternative source of energy or equipment.
What is an ashrae Level 3 energy audit?
ASHRAE Level 3 – Detailed Energy Modeling and Capital-Intensive Investments. The ASHRAE Level 3 audit, otherwise known as a comprehensive audit or a technical analysis audit, is the most involved and is most common for situations where major, capital-intensive investments are being considered.
What is ashrae level 3 audit?
The ASHRAE Level-3 audit usually focuses on a “whole-building computer simulation”, where some type of computer program is used to very accurately model how a brick-and-mortar building would react to changes in the energy systems, whether those are major HVAC retrofits or architectural modifications to wall space, ...
How much does an ashrae Level 2 energy audit cost?
$2500 to $10,000This is a more rigorous and time consuming process, more expensive, but generally more accurate (for energy projects where technical accuracy is critical). We call this analysis our ASHRAE Level 2 Comprehensive Energy Audit. Typical audit cost is $2500 to $10,000 depending on building size.
What is a preliminary audit?
What is a Preliminary Audit? A preliminary audit is fieldwork performed by auditors before the end of the period under examination. By engaging in this advance work, the auditors can reduce the volume of activities that must be completed after the client has closed its books.

How to measure humidity?
There are various methods for humidity measurements. Some are based on the determination of the temperature and partial pressure of the vapor in the gas like dew point determination: from these measured quantities, through a calibration and calculation process, the measurement of humidity can be derived. Others are based on wet and dry bulb temperatures. For fast and accurate measurements chilled mirror hygrometers (dew point) are fine.
What to look for when choosing an infrared thermometer?
Two things to look at when choosing infrared thermometers are the temperature range of the intended use and the measurement distance. Optics are given in a ratio such as 6:1 or 10:1. A ratio of 10:1, for instance, means that from a distance of 10 feet the sensor will be reading an area 1 foot in diameter.
Why are manometers used today?
One of the earliest pressure measuring instruments, manometers are still in wide use today because of their inherent simplicity of operation and accuracy. Manometry measurements are functions of gravity and the liquid's density. Manometers can be portable instruments used for direct pressure reading. When coupled with Pitot tubes it can be used for airflow pressure measurement. A low-cost and useful device for auditors.
What is the purpose of a thermometer?
Additionally, thermometers are used for measuring operating equipment temperature to determine process equipment efficiencies and waste heat recovery sources. Electronic thermometers with interchangeable probes are available for both cases. Some common types of probes are immersion probe, surface probe, and a radiation-shielded probe for measuring the true air temperature.
How much does a CEC hood cost?
It's easy to handle thanks to its flow straightener and tiltable display. Weights 6.4 lbs, hood dimensions are 24" x 24". The cost falls in the $1.8k - 2.2k range.
How do flow meters work?
The flow meters are used to determine the mass flow rate or the volume flow rate of a fluid in a pipe or in a duct, typically by measuring its speed. Portable instruments like ultrasonic flow meters allow measurements from the outside of the pipe without interference with the functionality of the system. Once the pipe's cross-sectional area is known it is possible to evaluate the fluid flow based on the flow speed measured by the instrument. A fluid's velocity measurement must take into account a number of factors that need to be provided by the auditor before the measurement process. Such factors are:
What is the accuracy of an IP54 thermometer?
This is an infrared thermometer for non-contact surface temperature measurement for -20 to 932°F (-30 to 500°C) range with an accuracy of +/- 1.5 degree. The distance-to-spot ratio is 10:1 with laser sighting for pinpointing the measurement area. Displays the minimum, maximum, differential and the average temperature values within the target area. IP54 rated for dust and water resistance. Applicable in electrical panels and wiring, mechanical, HVAC, and predictive maintenance areas.
