New Buildings Goals
Design versus Operational Performance New Buildings Institute report on the energy performance of 522 LEED-NC certified buildings found: • 50% did not meet design expectations • Many buildings performed worse than the ASHRAE baseline
Post - Occupancy Evaluation
Post - Occupancy Evaluation 1. Good building management high performance 2. Staff must be capable of use the installed building technology (Complex systems can take several years to refine and understand) 3. Commissioning high performance 4. Building occupancy changes Do our green buildings perform as intended? http://iisbecanada.ca/umedia/cms_files/Conference_Paper_1.pdf
Why Ongoing Commissioning? Initial operating efficiency vs. future efficiency The typical facility will become 3-5% less efficient every year without intervention.
Ongoing Commissioning-Smart Buildings Turning data into actionable items 1 Buildings from all over the world are monitored from a central location where data is gathered. When an anomaly is detected, the 2 data is analyzed by a Subject Matter Expert (SME). 3 A decision is made, and the proper course of action is taken.
