Commissioning

Commissioning is one way to ensure that a customer’s building achieves the expected performance level. Commissioning is used in many buildings in Europe and the United States and is one of the requirements for LEED certification. In Japan, too, the number of customers adopting commissioning is on the rise. Specifically, target performance, target values and the conditions for achieving them are clarified in the planning and design stages in a document called the Owner’s Project Requirement (OPR). The status of a building design, construction and operation are reviewed on the basis of this document. Air conditioning systems in particular are greatly affected by climate and usage conditions, making it important to quantitatively evaluate the level of performance achieved.

NSRI uses LCEM and other simulation tools to achieve a highly-accurate assessment of a building’s performance and present highly-effective proposals for improvement.
