Description
This General Specification aims to lay down the technical requirements of materials and equipment, the standards of workmanship, the requirements on testing and commissioning as well as requirements on document submissions for air-conditioning, refrigeration, ventilation and central monitoring and control system installation in Government Buildings of the Hong Kong Special Administrative Region (HKSAR).
The 2007 edition of this General Specification was developed based on its 2001 edition by the Air-conditioning Specialist Support Group (SSG) that was established under the Building Services Branch Technical Information and Research & Development Committee. Apart from the adoption of a new arrangement which gives the document a more compact and well defined structure, this new edition comprises revisions to incorporate updated international standards and covers technological developments which find applications in Hong Kong. The other emphasis is on green initiatives, e.g. reduction of construction waste and enhancement of client satisfaction on completed projects. This is in line with the department’s endeavour to reduce the environmental burden on our neighbours and help to preserve common resources while improving the quality of our service.
With the benefit of information technology, electronic version of this new edition is to be viewed on and free for download from the Architectural Services Department (ArchSD) Internet homepage. As part of the Government’s efforts to limit paper consumption, hard copies of this General Specification will not be put up for sale.
The draft of this edition has been circulated to stakeholders within and external to the Government before finalization. Nevertheless, the Architectural Services Department welcomes comments on its contents at anytime since the updating of this General Specification is a continuous process for the inclusion of any developments that can help meeting the needs of our community.
