Energy Behavior of High-Rise Residential Units in Hong Kong

To maintain relevance, Hong Kong Building Environmental Assessment Method (HK-BEAM) far residential buildings should be periodically updated to incorporate new environmental data, so extensive research an energy and environmental performance should be performed for high-rise residential buildings found in Hong Kong. This embraces various aspects such as building wall, door, window, and shading characteristics, and utilization in time and space patterns of activities in residential units. In this paper various design tools are described, simulation procedures outlined. Preliminary results show energy savings of roughly 8 % for an optimally placed insulation, and lower cooling demand of 14 % for a provision of additional concrete in the building envelope.
