Necessity for building physical performance analysis of complex project
Due to the illusion and delusion of building physics, the energy-saving design strategy with complex process of building physics shall be provided with a series of computer simulations for performance analysis and validation:
- Sunshine analysis
- Wind environment
- Natural lighting performance and shading strategies
- Energy consumption performance simulation
- Natural ventilation design and performance verification
- Thermal comfort performance

Additional value of the design caused by building physical performance analysis
Optimization of passive design: the optimization is beneficial to thermal Insulation, natural ventilation and the like due to the insulation, external shading, glass parameters, window size and location and etc.
Investment conservation: optimize the design according to the simulation analysis, and reduce the unnecessary investment
Improve the design quality: improve indoor comfort and lighting effects
Meet the requirements of green building: this the core part of the green building

Building performance simulation and green building
  
 
 

Energy consumption simulation: the energy-saving effect of the building is determined and designed according to the energy-saving standards
Daylighting simulation：the natural lighting effects of 75% of the main functional room are in line with the requirements (cloudy model)
Outdoor wind environment simulation：the wind speed of outdoor pedestrian area is not more than 5m/s
Natural ventilation：optimize building design, promote natural ventilation, and determine the effect of natural ventilation by means of ventilation simulation
Energy consumption simulation：determine the reference building and energy-saving effect according to ASHRAE90.1
Daylighting simulation： the natural lighting effects of 75% of the main functional room are in line with the requirements (sunny model)
