Energy Audits

Energy Audits

Primary focus of Energy Audit is to know the efficiency of the equipment or the system installed and to improve the efficiency.

Energy Audit studies have been instrumental in saving 7.5% to 25% of resource costs.

To explore the options for reducing energy wastage

To create an Energy Roadmap for implementation of effective energy strategy.

To minimise the wear & tear of the equipmentTo know the generation of green house gases or CFP level

To identify the design error/ occurring defects in the system

We have on board AARCS – A group of BEE Certified Energy Auditors – for conducting Energy Audits & verification of the savings realized by implementation of energy saving projects.
