Cost Cutting with Energy Audit

John A. Herbert
by John A. Herbert

A Kelcroft energy audit finds the ways to cut your costs, lower your building operating costs, without sacrificing occupational comfort.

Commissions are undertaken range from the small energy assessments to major projects.

EMSD energy audit

More than seventy five percent (75%) of buildings are operating incorrectly, have inappropriate maintenance contracts or waste money through inefficient energy usage. And all too often the energy management systems installed to reduce operating costs, don't function as intended, and actually waste energy.

You wouldn't operate your business without the advice of an accountant to oversee your finances. Likewise an annual energy audit ensures that your energy cheque book is balanced too.

Energy costs tend to rise every year, tariff increases are threatened, increasing energy costs impact your bottom line, Kelcroft's cost cutting energy audit helps reduce your energy bills.

Why Should I Get an Energy Audit?

Most of us know about low flow shower heads, CFLs and unplugging our cell phone chargers when not in use, but there is so much more. Real savings need a professional REA Energy auditor.

An energy audit is also an appropriate tool if you are considering an energy efficiency or renewable energy project. The energy audit can help you decide whether or not the project is truly worthwhile.


Kelcroft's approach is a holistic, total energy approach, it considers the total picture, not just the low hanging fruit providing an overall energy cost in use perspective.

The goal is management of resources without sacrificing end-user comfort. Our energy audits are conducted in accordance with international standards, and local EMSD guidelines as required.

One thing I have learned over the years is that energy auditing is not a desk job, it needs boots on ground, the site inspection of equipment actually operating is important, and very revealing.

If your energy auditor is not challenging and questioning your team, something is must be wrong. We ask thousands of questions about the operation of your building, and you will not be surprized to learn we get different answers to the same question, confusion over operations is a leading cause of energy waste.

Energy Audit Success Stories

Finding and identifying energy waste, energy auditing reveals the underlying losses you can only imagine, don't be left in the dark.

Lost Maintenance

A building owner in Hong Kong was shocked when we reported the cold hard facts...learn more

High Rise Waste

Another example of High rise waste, a commercial building operates six days a week? unfortunately the truth is stranger than fiction...learn more

Wrong Metering

For the last 10 years the building owner overpaid, the owner, the property manager, nobody knew until Kelcroft audited a TST commercial building reported an easy win, HK$ 75,000 per year cost saving, without any capital investment.

Lazy Commissioning

As part of a leisure complex energy audit, including swimming pool building, sports, and FB areas, lucky the owner included the brand new building within audit scope, opportunities abound...learn more

All Chillers, all the time

Kelcroft energy audit experts found that the central air cooled chillers were operating together, ALL chillers, ALL the time, irrespective of the actual cooling demand. The energy audit reported the BMS control problem, if rectified, it would result in significant cost and energy savings.


Kelcroft found that a central air conditioning system with the differential bypass valve broken, chilling and circulating water for no reason is expensive, the maintenance team were pushed to repair it ASAP.


A central air conditioning system with two central chillers was found with one chiller hunting (switching on/off/on) for no reason, excessive electricity consumption resulted. It also caused comfort problems for the shopping centre, and excessive wear and tear on the plant.

This finding alone demonstrates the need for individual chiller metering! without which, this major problem would never be discovered.

Twin Peaks

A central air conditioning system with central chillers served chiller water to local Air Handling Units. the control experts installed TWO separate Return air thermostats, one linked to control the AHU chilled water valve, and one to control the VSD operating the fan, Never control a system with twin inputs, that is control system course 101.

Missing Fresh Air

We discovered a building full of Air Handling Units, each with a brand new control system comprising a VFD for the fan and a Carbon Dioxide sensor. The only problem being the sensor, intended to act as proxy for occupancy, was installed in the outdoor air stream. We downloaded the data from the VFD, it confirmed the output frequency never changed.

EMSD Energy Auditing

An energy audit is the systematic review of each fuel, and energy consuming system in your building or facility carried out by REA

energy conservation

It commences with the collection, and analysis of all information that may impact the building energy consumption. That data is analyzed, the performance of existing systems examined, and existing management techniques reviewed.

Then we compare your facilities energy performance with published standards (benchmarks) for your premises and activities of a similar nature and provide proposals that are financially viable to lower energy costs.

A Kelcroft energy audit cuts energy costs, leaving more money in your pocket.

The role of the auditor is much like an accountant but for energy, the auditor will identifying past energy expenses (energy consumption) and proving the means to cut costs. Plus the eyes of a hawk to uncover problems with operations. That's why the auditor needs twenty years expereince, to understand the difference bewteen operations and wasted energy operations.

Kelcroft has experienced Registered Energy Assessor (REA) to submit energy audit report to EMSD (REA service)

Energy Audit Standards

Guidebooks for energy auditing, including ASHRAE, EMSD energy audit code provide the standard for conducting energy audits.

For Hong Kong BEEO energy audit, the standard is provided by the latest version of of the EMSD Energy Audit Code (EAC).

Energy Audit Report

The result of the energy audit is the audit report, Kelcroft's energy audit report includes our findings, and is sub-divided into three energy management sections, namely:

Within these three sectors, we explain energy saving options and opportunities for your review and implementation.

The energy audit is really only the first step, implementing the findings to lower costs is the ultimate goal.

Energy audits and energy auditing for buildings, including hotel audits, school audits, hospital audits, commercial building audits, office audits. buildings are high energy consumers and offering options for energy saving.


Housekeeping measures are low cost / no cost measures improvements involving relatively simple steps to start achieving energy savings. For example signage, and or training courses to increase energy consumption awareness amongst your staff.

Operation Measures

Operating and Maintenance measures are recommended improvements that necessitate some change within your existing regime or maintenance strategy.

For example lighting modifications, improved the switching arrangement or implementing a new lamp replacement strategy benefiting from the efficacy of the latest technology. Or perhaps re-commissioning to recover lost capacity.

In the majority of cases, the working environment for your customers is improved..

Capital Works

Capital works are major improvements to your premises or systems that will require significant expenditure.

Examining your installation, analyzing your operating and maintenance costs, and evaluating possible options for energy conservation.

Financially viable proposals that will benefit you! are offered for appraisal. There is not one correct answer for each client, each has different needs and goals. For example switching to water cooled air conditioning (cooling towers) or consideration of cost effective cogeneration solutions or perhaps waste 2 energy systems.

Energy Audit Financial Analysis

The energy analysis would comprise a practical and economic evaluation of viable energy saving options. This evaluation would include an investigation of all the various elements that contribute to your owning and operating costs. Typically these would comprise:

Each of the elements would be analyzed to gauge the overall economic viability of a particular energy-saving strategy or programme.

Initial expenditure

Defines the money required to purchase the plant or equipment (CAPex).

Cost in use

Cost in use is the operating and running costs for the installation based on the data retrieved during the energy audit (OPex.)

Investment analysis

Investment analysis comprises fiscal, payback and net present value calculations, these tools are primarily used to establish if a proposal would recoup your investment during a specific period.

Payback hurdles would be established to meet the needs of the organisation.

Energy Audit Experience

Kelcroft's long standing expertise can help implementation of energy audit recommendations, particularly our experience providing E&M capital works projects.

energy audit China, Hong Kong, Asia, energy chart by Kelcroft

We have conducted EMSD audits, ASHRAE, CIBSE audits, in fact the requirements are similar.

Because our knowledge, gained across three continents, is backed up with our experience from nearly thirty years building services design and operation we help organisations lower their operating cost so they can leverage that competitive advantage in the market place.

Our experience includes commercial buildings, shopping centres, clubs, offices, retail, recreation clubs, hotels, retail, data centres, and factories in Hong Kong and China.

When to conduct an Energy Audit?

In Hong Kong and Asia, the best time to conduct an energy audit is during the summer, when the largest temperature difference bewteen the inside and external conditions occurs, so in Hong Kong, that is June. Conducting an energy audit in the winter is pointless, the air conditioning equipment (largest energy contributor) is not loaded and under stress during the winter months, pick the hottest month if you can.
