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?

----- 4 ‘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

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 energyLong 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.
