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.

When an anomaly is detected, the data is analyzed by a Subject Matter Expert (SME). A decision is made, and the proper course of action is taken. Buildings from all over the world are monitored from a central location where data is gathered.

Ongoing Commissioning-Smart Buildings

Turning data into actionable items

Existing Buildings Goals

Improvement Potential

Building envelope improvements (new build and retrofits) are critical to achieving the targets

Building envelope improvements Equipment efficiency improvements
