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.
