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.
