  1. Part I Self Introduction Part II Background of research Information of Computer Simulation Part III Feasibility ot Computer simulation For Built Environment in China Part IV Benefit for China Part V Summary

  2. Introduction • University of Sheffield • School of Architecture • EBAU • PG Student • Research Area

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

  4. What is Computer Simulation? ----- combination of numerous and complex equations • How it works? ----- 4 ‘C’ Process • Development in the World single sheet --- calculaton by hour

  5. Current Situationin 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

  6. Concerned Strategy • Monitory • Financial & fiscal insentives • Information & training • Administrative support • Certification • Data Collection • Government • Climate data colletction • Material database • Construction database • Achitecuture design • IT support • HVAC severices ￣ ￣ ￣ ￣

  7. 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

  8. 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.
