“Integration of architectural design and engineering” is to consider the links between design and nature/society/technology. The past highly insulated and air-tight design is now reconsidered to allow air flow in and out depending on the changes of the internal and external environment. This integration requires information exchange tools between architects and engineers, and the tool is called as BIM, Building Information Technology. JCAP7 has full knowledge of this BIM to be adopted for the optimum design of the buildings.(BIM:Building information modeling).
