Energy Efficiency and Air Pollution

energy efficiency consultant, energylab, hong kong energy expert

Wondering why air pollution and energy efficiency are so closely related? 89% of Hong Kong electricity generated is consumed in buildings, yet as little as 10% of the primary energy is actually provides useful work. Therefore every watt you save counts. In the chart using 2006 data, the purple represents Hong Kong electricity generation by coal, the green fuel by gas (original chart by IEA http://www.iea.org/textbase/stats/pdf_graphs/HKELEC.pdf).


We assess your energy consumption to track down all the wasted energy, recovering that lost energy lowers your operating cost, the generator uses less coal, in turn that lowers air pollution. And many businesses don’t appreciate the business risk, at the time of writing energy audits are still optional, but that will not always be the case, carbon accounting will certainly become compulsory.

In other countries labelling is already compulsory, and building owners now must compete marketing energy consumption. Green building labels such as LEED and BEAM are one type of market indicator.


To understand and track down the energy losses takes experience, experience modelling energy, experience on the application of power consuming process and engineering operation.  energyLAB can find the energy losses and return those savings to your pocket.
