The Energy Audit
An energy audit provides enormous benefits. If you are determined to maximise energy and carbon performance while minimising operational costs, then an energy audit underpins strategy, tactics, and investment decisions.
Energy waste is invisible. The common expression ‘out of sight, out of mind’ means it's all too easy for those operating buildings and industrial facilities to go about business as usual unaware of needless energy wastage and excess carbon emissions.
A formal energy audit will provide an energy breakdown for a whole site, which underpins identification of wastage and savings opportunities, which in turn informs strategic reduction management decisions. The outputs of an audit includes technical description of improvement opportunities, capital cost estimates, projected annual savings, cost-benefit analyses, greenhouse gas savings, tariff analysis, and other benefits.
The depth, quality and value of an audit is only as good as the people conducting the audit. The Northmore Gordon auditing team brings deep technical expertise and industry knowledge.
Our energy experts and engineers are highly experienced in large-scale commercial and industrial operations and can provide the trained eye necessary to deliver an audit that not only upholds standards set out in AS/NZS 3598:2014, but leaves you with a solid list of improvement opportunities.
Implementing energy efficiency measures directly reduces operating costs and lowers emissions. Yet it takes a trained eye and a thorough inspection to identify waste, inefficiency, and opportunities. This makes energy audits a fundamental part of any effective energy management plan.
What can we help you with?
We find that businesses that haven’t conducted an energy audit in several years are likely spending 10-30% more on energy costs than necessary. This could be from inefficient equipment, poorly sized or specified equipment, poor control strategies, operations and maintenance practices, or a combination of these.
Technology is developing rapidly. Equipment that used to be efficient is now old or outdated, and modern plant control systems can better maintain efficiency at part loads. Plant services are a great place to look for these opportunities. For example, steam, compressed air, and chiller systems are commonly found to be running at low efficiencies. An energy audit provides performance benchmarking to evaluate their efficiency and determine steps for improvement.
Maintenance practices have a big part to play. For instance, a cooling tower system might have degraded fill, fouling, or poor maintenance of the temperature or pump control systems.
Operational procedures can be a cause of energy waste. For example, a facility with two boilers will operate more efficiently by running one boiler at 100% capacity with the other on standby than by having both boilers running at 50% capacity.
Sometimes relatively simple behavioural adjustments can allow for load shifting that results in significant energy cost reductions. For example, it may be cost-effective to stagger turning on equipment to avoid significant spikes in energy demand. Recognising and determining the impact of such adjustments requires a holistic understanding of the plant’s mechanical equipment, operational procedures, and utility rate structure.
The cheapest energy source is a facility’s unused energy. Energy audits are a critical step to identifying the flow of energy through a business, highlighting energy-intensive users and areas of waste, providing advice on the best energy tariffs, and recommending strategies to reduce overall costs.
