Building Science Mould (mold)

by John A. Herbert

We spend many hours inside buildings every day, whether its your office, home, or place of entertainment (cinemas, shopping centres, etc.) therefore the quality of the air we breathe everyday should be a very important issue, yet our buildings often let us down, mould (or mold) being a common issue. The key to avoiding mould (mold) is minimising moisture, and one of the key measures to manage moisture is good ventilation.

But ventilation alone does not tell the whole story because understanding the science, some might argue that is a lost art, is required to find identify source, and rectify problems.

Surface mould can be easily be seen, and washed down. But mould, hidden inside walls, and floors is far more difficult to detect, and once detected treated. Mould can cause health problems, allergies, for occupants, and moisture left unattended can even destroy the fabric of your building.

How to comply with BEEO ordinance for new construction?

To build in Hong Kong you follow the traditional BD submission format, but you must also fulfil the mandatory requirements detailed in the Building Energy Efficiency Code (BEEO). How does that impact the construction process?

The building owner must engage an EMSD Registered Energy Assessor (REA) to complete and issue EMSD Form EE1, also known as Stage 1 Certificate of Compliance Registration (COCR), and an EMSD Form EE2, known as Stage 2 COCR.

When does the COCR need to be issued?

Stage 1 COCR must be submitted within two months after obtaining BD consent. For Stage 2 COCR, that must be submitted within four months after obtaining BD Occupation permit.

further details are provided on the EMSD website.

BEAM Society Limited (BSL) celebrated its 5th year of incorporation with anniversary dinner on 25 Sept 2015 at the JW Marriott Hotel Hong Kong. This celebration belies the real age of BEAM, which commenced in 1996, progressed from a committee, into the BEAM society, becoming incorporated as BEAM Society Limited in 2010, and the #greenbuilding movement has steadily grown every year.
