Main Program
Building for People & Performance. Achieving Operational Excellence.

Presenter:
Darryl K. Boyce
ASHRAE President 2019-2020
Achieving Operational Excellence
Excerpt -
Why should we care about operational performance?
There are four reasons this message makes sense for us:
- We own the buildings we design, build, commission or operate. “It’s my building.”
- It aligns with our ASHRAE mission of “advancing human well-being.” I bet most of you think that the HR in ASHRAE stands for Heating and Refrigeration. However, it really stands for people, the human resource – the HR at the center of ASHRAE.
- As a building owner-operator, I can assure you that the building operators need your help.
- Reducing the environmental impact of building operations is good for the planet.
