A Hong Kong office indoor air quality survey released last week reminds us the office environment has improved little over the years, the findings show 27% of those surveyed report bad indoor office environment.
In the early 80’s the phrase poor Indoor Air Quality (IAQ) came to forefront. Many reasons were cited by the ac and heating experts as the explanation for the degrading office environment, the most likely culprit being the energy crisis. Dramatically increasing fuel costs encouraged building owners to use frugal quantities of outdoor air impacting the air quality. One result, a whole new range of terminology emerged including tight building, building related illness, sick buildings, and Sick Building syndrome.
The quantity of the Outdoor Air (OA) is obviously important, particularly in the regions with high humidity, causing a significant latent load. However, the source of the air is also critical, drawing Outdoor Air from a polluted source drags particulate matter and chemical pollutants into the office air.
If there is one solution, we must recognise that Green Building assessments including BEAM, recognises the importance of the indoor environment and the impact on productivity. BEAM Plus allocates 32 credit points to the indoor quality environment aspect. Furthermore it shows us that energy efficient HVAC solutions are needed to ensure the right quantity of clean Outdoor Air is provided when needed.

I was recently interviewed by the leading English language newspaper (www.scmp.com) on the topic of sustainability, and greening business. just in case you missed the article (68OK PDF one page, published 8-03-2010)

Later this year (2010) we will see the introduction of the energy efficiency regulations for commercial buildings downunder. So if you are selling or leasing commercial office space over 2,000 sqm, the building owner(s) are required to disclose it’s energy performance and efficiency. [Source SBE] This mandatory disclosure will require owners to obtain a NABERS (National Australian Built Environment Rating System) Energy base building star rating.
As I understand it, there will be no grace period following the passage of legislation, therefore building owners need to start considering these requirement before leasing or sale. The Australian NABERS system has accredited NABERS assessors that provide guidance through the NABERS process, to assess current energy performance and explore opportunities for improving energy efficiency.
Compared the BEAM Plus EB (existing buildings) methodology, NABERS it is a concise and focused scheme and was helped by support from the Australian government. Discussions have been on-going for some time here in Hong Kong to launch a similar scheme in Hong Kong, a founding committee was setup however funding was not secured.
