About Computer Simulation in Built Environment Background of the Technology Urbanization, industrialization, geographic mobility 40% of the annual energy consumption Potential Solution Features of Built Environment construction details; occupant patterns; local climate opertating schedule; efficiency of HVAC

What is Computer Simulation? combination of numerous and complex equations How it works? ‘C’ Process Development in the World single sheet --- calculaton by hour

Current Situation in China  2,000,000,000 M*M /Annual  80% high energy consumption & 2-3 times  Resource utilization; energy consumption; environmental polution  Computer aided thermal caculation  HVAC services power caculation  No tool to predict the integrated energy performance  No integrated appraisal of building energy and environmental systems at the design time

Short Term  Reach guided solutions in the building design and operation decision  Provide extensive performance information considering the dynamic behaviour of the system  Produce new systems that consume less energy Long Term  High technology electronics industry  conservation of natural resources  Sensible reuse of manmade resources  Maintainance of eco-system

The development of computer simulation for built environment can provide a realistic prediction of energy performance at the design stage The tool also gives practitioners the ability to appreciate the underlying behavior of a building system It will be expected to provide outcomes that better match Chinese society’s aspirations for sustainable practices, environmental protection and climate change mitigation.
