520 # $a A practical approach has been adopted throughout this study in order that the end results will have pragmatic value to the heating, ventilating and air-conditioning (HVAC) industry in Hong Kong.
520 # $a A sample database of 20 existing commercial buildings was established for further analysis of building energy use.
520 # $a A typical commercial building was selected for detailed study of energy use by MVAC systems. (Abstract shortened by UMI.)
520 # $a Heat gains through building envelopes were reviewed with reference to fundamental theory behind as well as the heat transfer equations presented in the literature. The prevailing methodologies of cooling load estimation and energy calculation were studied. Building energy auditing methods were discussed with reference to the local practice as well as international standards and guides. The common procedures of building energy auditing with three stages were outlined: historical data collection/analysis, preliminary site survey, and detailed energy consumption investigation.
520 # $a Indoor Air Quality (IAQ) has become a major issue in commercial buildings worldwide including Hong Kong. Ventilation rate is no doubt a critical element in the design of HVAC systems, which can be realized more obviously in railway train compartments where the carbon dioxide level will be built up quickly when the compartments are crowded during rush hours. A study was carried out based on a simplified model using a train compartment that is equipped with an MVAC system.
520 # $a Most of the local modern buildings are high-rise with enclosed structure. Mechanical ventilation and air conditioning (MVAC) systems are installed for thermal comfort. Various types of MVAC systems found in Hong Kong were critically reviewed with comments on their characteristics in energy efficiency as well as application. The major design considerations were also discussed. Besides MVAC, other energy-consuming components in commercial buildings were also identified, such as lighting, lifts and escalators, office equipment, information technology facilities, etc.
520 # $a Overall Thermal Transfer Value (OTTV) is a single-value parameter for controlling building energy use and is relatively simple to implement legislatively. The local government has taken a first step in reacting to the worldwide concern of energy conservation and environmental protection since 1995. Different methods of OTTV calculation were studied and the computation results were compared. It gives a clear picture of the advantages and limitations for each method to the building designers. However, due to the limitations of using OTTV as the only parameter for building energy control, some new approaches to a total control of building energy use were discussed and they might be considered for future revision of the building energy codes in Hong Kong.
