Updates from ASHRAE HQ Interim Meeting

Meeting to Review Comments

SPC 100 met in Atlanta at ASHRAE headquarters today to begin the process of reviewing comments from the APR review. A total of 197 comments were received, with most being detail oriented rather than larger, philosophical issues.

The committee took up two questions that came up frequently in the comments:

  1. Should the standard include Residential buildings, and if so, should they be treated in a separate section or sections?
  2. Should the bulk of the O&M section (Section 6) be moved to an Annex

On the first question, we decided to break out Residential buildings into a distinct section of the document. This should make it easier to use and easier to review for those who focus on the residential market.

On question 2., the committee decided to move much of Section 6 (6.2 and onward) into a normative annex. Since it is normative, it is still required for compliance, but the text in the main body of the standard will be shorter, and more clear. Our intent is to make the main body of the text reflect the primary goals of the standard and not to over-emphasize O&M. The committee has consensus that strong O&M practices are essential to energy efficient operation of buildings.

Hate to See Jeff Go

We are all saddened to learn of the passing of Jeff Park, former member of SPC 100. Jeff was a great guy to work with and we all miss his presence enormously. Friends of Jeff can see pictures, offer messages to family members, and make donations at

Floor Area Standardization

February 22nd, 2011 Comments off

There has been a lot of discussion of late regarding a unified definition for floor are to be used to calculate EUI. Here is a compilation of the info that I have on the subject to date.

If you have other relevant info for the discussion, please email to and I will post it.

Current definition in the standard is from Std-105-2007a:

gross floor area: the sum of the floor areas within the building, including basements, mezzanine and intermediate-floored tiers, and penthouses with headroom height of 7.5 ft (2.28 m) or greater. It is measured from the exterior faces of exterior walls or from the centerline  of walls separating buildings but excludes covered walkways, open roofed-over areas, porches and similar spaces, pipe trenches, exterior terraces or steps, chimneys, roof overhangs, and similar features.
