Energy Auditing Service

The purpose of an energy audit also known as energy assessment or energy study is to find out why, where, how and when is energy utilised in a facility, and to discover occasions to increase efficiency. Energy auditing services are provided by energy services companies, energy experts and engineering organisations. The energy auditor directs the audit process but functions watchfully with staffs, building owners and other key participants all the way through to make sure precision of data collection and correctness of energy efficiency suggestion.

Why is Energy Auditing Done?

With the rising energy expense, you facility or business might be in jeopardy if sufficient action isn’t taken and you keep guessing the energy use versus financial plan equation. Energy audits helps to find out where you are throwing away energy in your facility. Domestic and industrial properties account for around 15% of carbon emissions in the UAE, according to the EPA, which means they are uneconomical and inefficient. Carelabs is there to guide you on which techniques are beneficial for decreasing energy waste and overall energy expenditure.

When considering energy, a smaller amount is always applauded. Less energy utilisation equals less energy expense. And, also, less energy utilization is clearly worthy for the environment.

What is Done During Energy Auditing?

Similar to any other audits, energy audit will evaluate all of your facility’s energy usage and sketch all of the details. It is a procedure that assists you to check where your property is wasting energy and what actions you can take to increase energy efficiency. An energy audit is something that all facilities must undergo every two to three years in order to make sure utmost efficiency and expenditure.

There are three phases in an audit based on the requirements of the client:

Investigation Phase

This phase is about getting all the information concerning:

• Historical energy consumption for the past 1 to 2 years
• Tariffs and related energy supply contracts
• Floor areas, staff numbers, production levels
• Occupancy hours
• Industry energy use/cost benchmark levels
• Sub electrical and gas metering equipment
• After-hours air conditioning usage
• Mechanical plant configuration, as-installed drawings, electrical single line drawings, and operational & maintenance manuals
• Lighting configuration, condition and controls
• Compressed air system including rating, presence of air leaks, hours of usage
• Steam and hot water boilers
• Building Management Systems and control strategies
• Building envelope, shading, orientation, insulation levels
• Energy management process and policy information
• Asset management plan, if any

Monitoring Phase

This phase is about getting data related to the entire site and the main energy usage groups. The function of main plant and gear is checked, and measurement of a scale of parameters i performed where necessary, including:

• Electrical & gas load profiles
• Internal temperature/humidity
• Ventilation rate
• Light levels
• Boiler flue combustion analysis

Response is also attained from maintenance workers on subjects regarding building and plant functioning and repairs which could be affecting energy efficiency as well as causing inhabitant discomfort.

Analysis and Reporting Phase

This is about:

• Finding out complete energy efficiency of facility
• Finding out the greenhouse emission index(GEI) and ABGR energy star rating for office structures
• Life cycle cost analysis of various energy saving measures
• Tariff analysis
• Top demand management including assessment of power factor correction
• Noted down and if required, verbal report on results

How is Energy Auditing Performed?

Preliminary review of utility data

• Inspect equipment lists, utility data, building diagrams, and other property information
• Auditor gathers and review at least 2 years of utility data during the energy use analysis to account for seasonal variations and patterns of energy use (Monthly utility bill data is most commonly used)
• All forms of energy (electricity, gas, oil, water) should be included in this analysis
• From this evaluation, your facility’s Energy Utilization Index (EUI) value (annual energy use/square footage) and energy end uses (energy used by each building system) are calculated
• The Energy Utilization Index (EUI) and base energy load allow the auditor to target this data against energy usage of similar buildings and systems to show the magnitude of energy efficiency options and give an early estimate of potential savings
• Auditor also checks for the difference in usage of energy with time and reasons for the same
• Auditor will give an initial report which contains a summary of information and graphs and other visuals to permit easy interpretation.
• Outcomes from the study is used in determining which level of audit to run and get data for the final report
