Energy Audits

An energy audit is the first step to assess how much energy your home or facility is consuming and identifies measures that you can undertake to

  • make cost savings (domestic, commercial and industrial premises)
  • improve production efficiency (commercial and industrial premises).

Our engineers are qualified for conducting energy audits according to ISO50002.

If you need more information do not hesitate to contact us.

The first step you need to undertake to make your home run more efficiently and save energy is to conduct an energy audit! Homeowners can save up to 30% on their utility bills.

Our engineers can help you achieve such savings. We provide two levels of home energy audits

  • Walk-in audit
  • Detailed audit (consists of a walk-in audit, energy metering and thermographic scans)

Our professional team will visit the client’s residence and carry out a room by room inspection. A thorough examination of past utility bills will then follow. The auditor will ask a couple of questions to determine the residents’ behaviour. From this information, the auditor establishes why, where and when energy is consumed and gives the client his advice on measures he can take to save energy. Finally the client is presented with a report of the findings and the auditor recommendations.

An energy audit at your commercial premises is the first thing that you need to perform in order to reduce your operation expenses and become more competitive. Up to 40% of the energy used in commercial premises can be saved.

JL & Associates apply a systematic approach to conducting energy auditing and it is as follows: Our engineers will visit the client’s premises and carry out a walk-in inspection. A thorough examination of past utility bills will then follow. Next, the auditor will carry out measurements and data logging to determine the energy usage patterns and behaviours. From this information, the auditor establishes how the energy is being used. Finally the client is presented with a report of the findings and the auditor recommendations for energy savings.

Starting with the legal obligations of an energy audit, LN196:2014 states that all companies registered in Malta that are classified as a non-SME it is mandatory for them to undergo a level 3 energy audit in line with ISO50002 requirements. All our engineers are fully qualified to conduct energy audits according to ISO50002.

We take the following systematic approach to energy audits:

  1. First an evaluation of the facility is conducted followed by a careful examination of all utility bills and any sub-metering records available.
  2. Definition of the scope and boundaries of the audit to allow us to focus our efforts where there is the largest energy savings potential.
  3. Conduct measurements and data logging in startegic locations for a number of days/weeks depending on the activity of the facility.
  4. Analysis of the data and identification of potential energy savings opportunities.
  5. Cost benefit analysis of the recommendations

Following an enegry audit our clients will be presented with an audit report with all the measured data, its analysis and findings, recommendations including payback analysis. This would allow our clients to prioritise their energy saving actions.
