Optimizing Energy Efficiency for a High Rise Office Tower in Tropics
A detailed building energy simulation study showed that it is possible for a building owner in a proposed multitenanted high rise office tower to reduce up to 73%energy consumption as the operator of the building.This energy reduction reduces the energy running cost for the building owner from a baseline of RM 2 million per year to a running cost of RM 500,000 per year.The building energy intensity of the building(including tenant energy consumption)reduces from 212 kWh/(m2.year)down to 82 kWh/(m2.year)A holistic energy efficiency approach was proposed to achieve such high efficiency gain.Approximately 50 passive and active energy efficiency features were tested for this building.Many of the efficiency gains are in the region of 1~2%energy reduction per design improvement.In addition,the peak cooling load of the building was reduced by 34%due to these design improvements,allowing a smaller air-conditioning system to be implemented for this building.The energy efficiency passive and active design features that will be implemented in this building is largely considered conventional design practises.However,by making small improvements at every design opportunity,the building can be made very efficient at minimal additional cost to the building.In addition,due to the smaller airconditioning system,there is a cost reduction that would help to finance the design improvements proposed.
