WHAT ARE THE BENEFITS OF AN ENERGY AUDIT

Our experience for medium to larger energy users is that when you prepare an energy audit, energy cost savings can be significant.

Benefits of an energy audit as per the Australian Standard with Websters Group include:

Access to world-leading expertise in energy efficiency

Address strategic risks, fix problem areas and identify inefficiency

Achieve deep reductions in energy usage (target 30% to 50%)

Improved gross margins through significantly lower energy costs

RECENT EXAMPLES OF MEDIUM SIZED BUSINESSES THAT BENEFITED FROM AN ENERGY AUDIT:

REAL SITE MEASUREMENTS MEAN REAL SAVINGS

Our audits use portable smart metering and data logging extensively to bring
engineering models together with real world data.

Ultrasonic flow metering equipment is used to provide quick and accurate measurements of liquid flow rates. This equipment attaches straight to the pipe and eliminates the need install or rely on existing water meters that are often inaccurate. This is also useful for quickly measuring other liquid flow rates i.e. within food manufacturing.

THERMAL IMAGING TO HIGHLIGHT PROBLEM AREAS

Given electrical energy is often lost as heat, thermal imaging is an important part of the site review process. Identification of air flows, pipe insulation, cold storage operations are a few important applications.

Understanding power drawn from various areas and pieces of equipment is key to understanding peak demand charges. We use licenced electricians to review each major electrical load in the distribution or main switch board(s). Breaking down site usage to this level helps unlock really important facts about peak demand charges at your site.

REVIEWING PEAK DEMAND COSTS

DETAILED ENERGY MODELLING

Once we have obtained these detailed measurements, we breakdown energy use and costs by area or equipment type in an Energy End Use Breakdown.

BRINGING PROJECTS TOGETHER FINANCIALLY

An energy audit will generally pay for itself many times over through identification of low and no cost energy saving opportunities. Larger capital items can also be included that have long term cost savings and maintenance benefits.

An example of the financial savings from an energy audit and subsequent upgrades are below (based on an average from three audits in 2020).

Year 0 1 2 3 4 5 6 7 8 9 10
Energy Audit (Websters Group) $ (9 800)
Upgrade Costs (10 – 15 projects) $ (109 380)
