Hotel Energy Audit
by John A. Herbert
More than seventy five percent (75%) of buildings are operating incorrectly, have inappropriate operating and maintenance contracts, or waste money through inefficient energy usage.
Your business expenses in the energy category tend to rise every year, the threat of tariff increases or fuel surcharges add further uncertainly and cost, but the price keeps climbing and that drives up the operating cost of your hotel, and drives your profit down.
energyLAB’s hotel energy audit (能源審核) is a methodical looking at your present energy consumption, it identifies energy waste, and cost savings. Implementing the energy audit recommendations should lower your operating cost without sacrificing occupational comfort. It also should improve your energy efficiency, and potentially provide annually recurrent cash savings that often exceed the cost of the audit.
Hotel’s are different to other building types, they have occupancy and operations unlike traditional office buildings, and it is important issue, often overlooked.
Our long standing international expertise can help design, auditing and implementation of energy audit recommendations, particularly our experience providing E&M capital works projects.
We have unique knowledge, gained across three continents, backed up with our experience from many years of building services design and operation. We help organisations lower operating cost to leverage a competitive advantage.
We have already undertaken energy audit projects in Hong Kong, Macau, China and Asia.
Registered Energy Assessor
Our in-house Registered Energy Assessor (REA) can provide certified energy audits in accordance with Hong Kong Building Energy Efficiency Ordnance.
Don’t be left in the dark
It should be no surprise that your competitors already enjoy higher profit resulting from saved energy, they have the competitive advantage.
energyLAB’s Energy Auditing Methodology
We take a complete and holistic view of the operation, our energy audit considers the total picture, not just the low hanging fruit using an overall energy cost in use perspective, a energy audit report with only three recommendations is not a complete energy audit.
An energy audit is the systematic top down review for each fuel (gas, oil, electricity, LPG) and system in your portfolio. Information that impacts your building energy consumption is collected and analysed.
The condition and performance of existing systems, installations, existing management techniques, and utility bills are examined.
Once the analysis is complete, we can then compare your energy performance with published standards (benchmarks) for other hotels. Energy auditing needs to be conducted on the ground, an audit can’t be effective without inspecting the nuts and bolts on site that is the secret to energyLAB’s proposition. We find and identify energy waste revealing the underlying losses. One classic example in Asia, escalators operate in both directions, with electrical motors spinning at full speed whether or not people need them.
The goal must be to provide guidance effective management without sacrificing end-user comfort. Our energy audits exceed international standards, and local EMSD audit guidelines.
Anatomy of the Energy Audit Report
The annual energy audit is much like your annual accountant review, stating your past energy usage, we summarize our energy audit report findings into three energy management sections, namely:
- Operation & Maintenance
- Capital works
Within these three sectors, we explain energy saving options and opportunities for your review and implementation.
Housekeeping measures are generally improvements involving virtually no cost, and involve relatively simple steps to start achieving energy savings. For example training courses to increase energy consumption awareness amongst your staff.
Operation & Maintenance
These improvements 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. In the majority of cases, the working environment for your customers is improved.
Capital works would be major improvements to your premises or systems that will require significant expenditure. Examining your installation, analysing your operating and maintenance costs, and evaluating possible options for energy conservation. Viable proposals that will benefit you financially are offered for appraisal. For example switching to water cooled air conditioning (cooling towers) under the Hong Kong pilot programme or consideration of cost effective cogeneration solutions.
Financial analysis is a critical point, whilst the energy analysis would provide the practical advice, it is the economic evaluation of viable energy saving options that will contribute to future profits. Our financial evaluation using typical tools would include an investigation of all the various elements that contribute to your owning and operating costs. Each of the elements would be analysed to gauge the overall economic viability of a particular energy-saving strategy or programme:
- Initial expenditure (CAPex)
- Cost in use (OPex)
- Investment Analysis
The Capital Expenditure (CapEx) is the initial expenditure, the money required to purchase plant, system, or equipment.
Operating Expenditure (OPex) means the cost in use, it is the operating and running costs for the installation based on the data retrieved during the energy audit.
Investment analysis is the financial engineering, comprising 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 Standards
There are several published reference standards but not all standards are equal, energyLAB has the competency to conduct Energy auditing in accordance with any of the following energy audit standards.
- Energy Audit Code 2012 (BEEO) – EMSD Hong Kong
- Energy Audit Guidelines – EMSD Hong Kong
- Procedures for Commercial Building Energy Audits- ASHRAE
- Energy Audits – Australian Standard AS 3598:2000
