Simulation Aided HVAC System Performance Assessment During Design Phase of an Office Building Complex

Abstract

 The investigation presents a strategic approach during the design process using advanced energy performance simulation technology. Team coordination and building performance efficiency during the design process is aided by conducting a performance based assessment with comprehensive fully incorporated design, construction, energy, HVAC and annual building operation. The simulation methodology aids the performance based decision making which demonstrated through an office building complex. The engineering decisions were based on performance enhancement and overall energy demand reduction, which was evaluated on an annual basis. The building envelope‘s dominant curtain wall system was analyzed in detail in order to demonstrate qualitative energy performance improvement. VAV and DOAS HVAC systems‘ annual energy performance was estimated and evaluated from the aspect of end-use energy.
