Energy Audits

Energy Audits can be undertaken for planning capital investment, process analysis, energy reduction, and establishing a baseline for performance benchmarking.

The effectiveness of an audit is dependent on the understanding of the system function. G2 TECH technicians have many years experience in designing, installing and maintaining Hot/Warm water, Process hot water, and filtration/disinfection systems. This underpins our ability to provide the following:


Items typically covered in audits include:

BUILDING CONSIDERATIONS – Access & egress, plant room design and ventilation.

EQUIPMENT CONDITION & COMPLIANCE– Compressors, heat exchangers, evaporators, condensers, desuperheaters, pumps.

PIPING SYSTEMS – Piping & valves, safety relief valves and flue systems

PRESSURE VESSELS – High and low pressure receivers, accumulators, inter-coolers, expansion vessels.

PROTECTIVE SYSTEMS – Insulation, vapour barriers, insulation media, jackets, protective coatings

G2 TECH will make an assessment of current plant efficiency and reliability and recommendations for improvement based on:

SYSTEM – optimization (correct loading), and integration can ensure maximum system efficiency. In addition the implementation of new or alternate energy or process systems can improve energy efficiency and reduce operating costs.

PLANT – heating, and cooling, and alternative energy can reduce energy loads – Energy Efficiency Exchange shares best practice information by industry sector, technology and energy management initiatives. 

EQUIPMENT – energy efficient choices for new equipment, and the replacement of older components and equipment with higher efficiency models when feasible - energy rating information can be found on E3 Equipment Energy Efficiency.

PREVENTATIVE MAINTENANCE – when implemented will ensure equipment is operating efficiently and at optimal performance.

Plant energy audits are comprehensive evaluations of the actual performance of a plant’s energy using systems and equipment compared against the designed performance level or the industry best practice. The difference between observed performance and “best practice” is the potential for energy and cost savings.
