energy audit: inefficiency

by John Herbert

Part of the energy audit process should be to review the condition of the plant, and equipment, generally if problems are discovered these can be categorized as deferred maintenance.

Here an example, an 800 mm axial fan, and a key part of the extract system providing mechanical ventilation. The photograph of the suction side clearly shows the flexible connection is ripped, and the discharge side was similarly damaged.

The extract fan was operating, still moving air, and consuming amperes, but the ‘system’ was not functioning. The failure points occurred at the highest pressure (discharge side) and lowest pressure (suction side) regions, that means little air movement could occur inside the ductwork.


Now explain to the management why they paid for electricity for the whole of last year, but no mechanical ventilation was provided.

For an energy audit, that complies with EMSD Energy Audit Code, call the energyLAB experts today!

COP21 means 2 degC or bust?


COP21 commences today, with leaders from 200 counties meeting in Paris, and buildings, for the first time, will be in focus, a milestone indeed.

Its important for Hong Kong where buildings consume 90% of the electricity generated, equating to about 63% of the cities carbon load. But bear in mind that Hong Kong is a high density city, with little industry left, it is almost entirely a service economy, but in terms of emissions although Hong Kong is a well developed economy, it is counted as part of China.

So in principle idea, limiting atmospheric temperature rise to less than 2 Deg C, is a moot point really, since we half way already, the first 1 Deg C rise has already occurred. But the focus on buildings is timely, not only for Hong Kong, but across Asia, where energy efficiency building operations is low priority for most.

I have yet to see any silver bullet solution, or even close, what is required is dedicated hard work, simultaneously on several fronts, to lower emissions, and then keep them low. Look at this year, 2015 has been the hottest year on record so far, all other factors being equal, your air conditioning energy consumption and bills will be highest on record too.

You have already have a full plate, right? You staff to manage, administrative work to handle, shareholders to satisfy,  profit targets to achieve, and competitors taking your market share, etc. but can you really afford to leave money on the table? Your competitors energy savings has give them extra cash, maybe it funded a killer marketing campaign. You may not know it but you need expert help starting right now!

If you know buildings as well as we do, then you know there are countless opportunities to manage and reduce your energy consumption. It cant be once a year, or once every ten year effort, you need to continuous manage energy, the same as other aspects of your business and one of the easiest ways to manage these buildings is by installing the quietest portable generators.

Capturing lost electricity capacity in your factory or manufacturing facility

factory electrical power capacity recovery, energyLAB, Hong Kong, energy audit

Capturing factory/manufacturing electrical power capacity recovery is cost efficient

Successful manufacturing business’s often outgrow the installed electrical power capacity in large facilities, those transformers that seemed ‘plenty big’ at the design stage are now fully loaded, and you face extra costs, production disruption to expand your operations.

Help is at hand, before you embark upon that expensive upgrading programme, first call energyLAB experts, we can help your business, we would conduct a feasibility study, using the same skill set we employ to conduct energy audits, to identify waste within your existing plant, releasing that lost electrical capacity for the new line, latest equipment, etc.

We have the latest tools at our finger tips, and the knowledge gained over decades, to identify all the opportunities.

The benefits are clear, using the existing electrical services infrastructure will be far cheaper, and saving time compared to installing new transformers and the associated utility, metering, MV and LV distribution boards, and cabling required to upgrade. You can visit Utility Saving Expert, to see how you can make your electric bill cheaper. There are commercial considerations too, where time, and time to to market is important for you, speed is key.  We can capture any lost capacity in your electrical system significantly faster than the time needed to plan and install new transformers rooms, transformers, utility feeds, etc. etc. and you’ll beat the competitors hands down!

In studies we have identified a variety of fixes, including electric meters that were still connected, but not actually used!

How it Works

energyLAB would send an engineer to review your facility, examining the electrical distribution network from the energy saving perspective, our feasibility study provides a roadmap to recover lost capacity.
