|Abstract:||In offices, the quality of the indoor environment, as defined by the physical indicators for thermal comfort, lighting, noise, indoor air quality, etc., is paramount to the maintenance of a productive workplace. Poor quality has a definite negative impact, somewhat defeating the purpose of the building. In Hong Kong’s commercial environment high-rise office premises are often part of a building complex housing other types of premises. Offices are sold or leased to multiple tenants. The centralised air-conditioning system together with other building services are the responsibility of owning or managing company, whilst part-owners and tenants generally take care of lighting and small power provisions within their spaces. Tenants may be free to install and modify layouts and fittings within fairly loose tenant fitting-out conditions and guidelines. There is no single performance indicator for indoor environmental quality (IEQ). Even for IEQ components an indication of quality performance may be to satisfy only a majority of building occupants, e.g., indoor air quality criteria seeks only to satisfy some 80% of occupants. In reality, the indoor environment varies between floors and premises, and within floors of the same building. Establishing performance criteria for the various IEQ parameters is not too difficult, but deciding on an assessment method that verifies compliance is much more problematic. The final outcome for IEQ depends on system design, commissioning, operation & maintenance, building management and tenant actions. Indoor conditions vary with season, occupancy levels, and workplace activities. This begs the questions of how, when and where to verify the various IEQ parameters. This paper reviews the approaches either presently adopted or under review, for use in the Hong Kong Building Environmental Assessment Method (HK-BEAM). The scheme, which was started in 1996, covers both new and existing air-conditioned office buildings. The developers of the scheme seek to provide the most suitable approach to check IEQ criteria against internationally accepted criteria. To gain acceptance in the marketplace these methods must take account of commissioning methods for new buildings, and the problems of assessing buildings which are already occupied.|
