TC 9.9 (formerly known as TC9 HDEC) is concerned with all aspects of mission critical facilities, technology spaces, and electronic equipment and systems. This includes data centers, computer rooms/closets, server rooms, raised-floor environments, high-density loads, emergency/network operations centers, telecom facilities, communications rooms/closets, and electronic equipment rooms/closets.

Our members offer their wide knowledge on these topics in the many different activities performed by our committee.

Programs: The Committee sponsors symposia, seminars and forums at the ASHRAE Society national meetings.


Research: The committee has developed a research priority list that aligns with both committee and ASHRAE goals. We have one research topic in the work statement phase.


Handbook: We aim to provide our assistance in the writing and revision of those chapters in the ASHRAE Handbook which relate to our field of expertise.


Standards and Codes: We are also involved with the writing and revision of standards.

The meetings represent a good way for TC members to become closely involved with the activities of the committee.
