The Field Measurement of The Sustainable Office Building with The Environmental Adjustable Systems

HVAC load weighs a large portion of overall building energy consumption. A low storeybuilding of 20,000m2 floor area adopted a task ambient conditioning system (TAC) to reduceHVAC load while maintaining work environment. Other design techniques such as doubleskinfacade and structural thermal storage system, were also applied and the TAC systemachieved comfortable personal work-environment with reduced demand.
