During the design stage, extensive computer simulation of the diamond form was conducted to ensure that the expected daylight and energy performance are met. In order to maintain the occupants’ visual comfort, various daylight simulation exercises were conducted to ensure adequate and well distributed daylight. These exercises also provided useful information on the appropriate measures that can be adopted in reducing energy consumption without compromising the occupants’ comfort level.
The building energy index (BEI) is a measurement on the total annual energy used in a building in kilowatt hours (kWh) divided by the floor area in square meters(m2). The BEI of a typical office building in Malaysia is 210kWh/m2 per year. The Diamond Building is designed with a BEI of 85kWh/m2 per year at 2,800 hours usage - a 65% reduction in energy consumption. At present, the building’s average BEI is at 65kWh/m2 per year.
The Diamond Building’s design strategy is encapsulated through four main aspects, namely Energy Efficiency, Water Efficiency, Indoor Environmental Quality and Outdoor Environmental Quality.
