THE PRACTICAL APPLICATION OF BUILDING SIMULATION TOOLS IN DESIGNING A REAL BUILDING
Peter Simmonds, Bungane Mehlomakulu
uilding Energy simulation tool and a Thermal Comfort simulation tool were used to design, select and specify various components and combinations of components for a 1.3 million square foot building in Los Angeles. The Thermal Comfort simulation tool was used to optimize the design of the conditioning system for the building occupants. In addition, various alternatives were analysed, and different operating and redundancy scenarios were investigated. The parameters from the optimized comfort design were then integrated into the operating schedules of the building simulation tool. The building simulation tool was used to define the operating energy consumption of the building as well as refine operating strategies for a fully and partially occupied building. One of the major concerns of the client was the design of the chiller plant, specifically: the number of chillers, the number of chillers operating at one time, chiller plant redundancy and the possible requirement of a dedicated night time or weekend chiller. This paper will explain the criteria for designing and operating comfortable work spaces and how these optimized designs are integrated into the simulation to assess building loads, lower energy consumption and enhance overall building performance.
