To realize a “green building”, the commissioning process of designing is vital. Projects adopted in the sustainable building pilot program were investigated by interviewing designers, engineers and consultants. Commissioning works such as various goal settings, responding to the index standards and certification systems, utilization of computational simulation and measurement technique could be seen during the design process. Designers and engineers are expanding their expertise to assess environmental aspects, while collaborating with consultants to create sophisticated simulations and measurements in their design. However, in several projects, international standard such as performance goal-settings and analysis in early design phases were unaccomplished.
