by John A. Herbert

How to comply with BEEO ordinance for new construction?

To build in Hong Kong you will need to follow the traditional BD submission format, and also fulfil the mandatory requirements detail in the Building Energy Code.  How does that impact the construction process?

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

When does 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.

 

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.
