Guideline 36 was created by ASHRAE’s Technical Committee 1.4, Control Theory and Application to maintain and publish best-of-class control sequences that meet or exceed the requirements of published ASHRAE standards such as 90.1, 62.1 and 55. These sequences are intended for use with fully programmable DDC BAS systems controlling variable speed/capacity equipment.

The first public review of the Guideline was formally released on June 24th 2016. The deadline for comments is August 23rd 2016 (after the 60 day public review period).  You can download a copy of the public review draft here. Public review comments should be submitted to the ASHRAE website. Instructions for commenters can be found here.

The Guideline’s first formal publication will be high performance control sequences for airside HVAC equipment, including single zone VAV AHUs, multiple-zone VAV AHUs, and a variety of VAV terminal units.  These control sequences are based on Task 2, the written English language sequences of operation, from ASHRAE Research Project 1455, “Advanced Control Sequences for HVAC Systems – Phase I Air Distribution and Terminal Systems.”

The purpose of this review is to gather input on these sequences of operation, to distribute the sequences for control manufacturers and researchers to test, and to solicit other sources of best-of-class sequences to consider for future inclusion in Guideline 36.

The GPC meets at the Annual and Winter Meetings on Mondays from 8am noon local time.  We also have monthly net meetings that are normally held on the 2nd Thursday of each month from 8am-10am Pacific Time.  Go to the Meetings Page for the details.

In addition to help in writing the guideline we need control manufacturers and facility owners to participate in the programming and testing of these sequences in their hardware and facilities.

Please share this site with other potential interested parties, and have them contact Mark Hydeman  if they are interested in joining this committee.  We will need lots of help to get this important publication completed.
