secret life of Variable Speed Drives by John A. Herbert

Following the success of the secret life of chillers, the secret life of Variable Speed Drives (VSD) might be equally important.

Variable Speed Drives (VSD), also known as Variable Frequency Drives (VFD) can replace motor starters and lower energy costs, but this graph above (real data) shows the motor speed remains pretty constant all day long.  Continue reading

No excuse to delay energy upgrades on HK Island by John A. Herbert

Funding Energy Upgrades

Cost is always the key issue for energy upgrading projects right? Yet dollar matched funding, upto HKD 200,000 is available for residential projects on Hong Kong Island. For example, for Incorporated Owners (IO) where the total cost of your energy saving project is for example HKD150,000, HKD 75,000 is refunded!

Infra-red scanning tool is the latest high technology tool for surveying the condition of M&E services and buildings. the condition may appear normal to the naked eye, but infra-red imaging reveals subtle details not normally visible to humans and presents a false colour image for easy review.

You Are Paying Too Much…

The shoes you wear, office management fees, your photocopier, the equipment you order, you are probably paying too much, and it’s not because of you are a lazy shopper, it is because the overwhelming majority of businesses are energy inefficient. That shopping centre you visit for the weekly shop, the factory making your computer equipment they all waste far too much energy, you know they don’t run at loss, they simply pass that extra cost burden onto you.

Here in Hong Kong, buildings contribute more than 63% of the city’s carbon footprint, yet we have air conditioning systems, ventilation system, and escalators operating when there is nobody around. We also have oversized electrical motors running at full speed, when half speed is suffice. We have lighting used 24 hr, when daylight is available, and many more lost chances that can be listed here.

As a Registered Energy Assessor (REA) I know there are countless opportunities to lower operating costs, but you chose the companies you do business with, have they conducted an energy audit?

Should you care because you are paying too much.

Tree Hugging 2.0 by John A. Herbert

by John A. Herbert
Looking back over the last decade undoubtedly progress has been achieved, it cannot be denied, the relentless work of the few has moved the masses, that in turn increased corporations environmental awareness or has it?

In the USA, Unilever removed water from their detergent, the concentrate requires less volume, less packing, costs less to produce, and ship. In the UK, Marks and Spencer created Plan A with the goal to source responsibly. In China it was announced that all government vehicles, including the City and Province administration, shall use alternative fuel by 2016, and many others have joined the clan. But some businesses never made it, indeed we might need an endangers species list for businesses, and I’d put travel agents high on that list to follow the Dodo. Businesses that once relied upon scarcity of information, like booking an oversea hotel, have been overtaken in the internet age, it is easy to book your entire trip with only your phone. I am sure you can think of a few business models that will soon be defunct due to the internet, equally businesses that operate unsustainably the writing is on the wall too.

And amidst the usual corporate alphabet soup CSR seems to be lost cause, surpassed by the appearance of ESG (Environmental, Social, Governance) which is defined by the Financial Times as a generic term used in capital markets and used by investors to evaluate corporate behaviour and to determine the future financial performance of companies.

However, EMSD data reports the total annual energy consumption trend in Hong Kong continues to rise, which is disturbing and I find contradicts the great progress reported.

Unsurprisingly, listed corporations are hiring, but not energy managers as you might think, but ESG managers. Real sustainability demands action on energy period, there is no shortcut, without energy ESG managers are superfluous if there is no business to evaluate.

Firms to watch are those businesses that have already saved millions of dollars reducing costs and risk through sound energy planning.
