ORGANIZATION
 
This section describes the current structure and organization of SSPC 135.
 
Basic Facts about SSPC 135
 
SSPC is a "Standing Standard Project Committee" as defined and authorized by the ASHRAE Standards Committee. An SSPC is charged with the maintenance and enhancement of an ASHRAE standard where it has been determined that a group of experts needs to be available to answer questions, render interpretations, and, in general, maintain a standard after it has been promulgated. This is of particular importance with a standard such as BACnet that involves a highly dynamic field, in this case computer data communications.

The activities of the SSPC are governed by the "Project Committee Manual of Procedures (PC MOP)" which is available from the Manager of Standards. There are two forms of standards maintenance: periodic maintenance and continuous maintenance. In the former case, the standard is reviewed on a five-year cycle. At the end of the cycle, the standard must be reaffirmed, modified, or withdrawn. In the case continuous maintenance - the mechanism that applies to BACnet - the standard is subject to continuous, on-going refinement and reaffirmation.

 
Membership
 
Membership on the SSPC is open to any interested party "knowledgeable in the discipline of the standard" subject only to a few minimal constraints: there can only be one voting member per organization and the committee membership must be balanced with respect to "producers," "users," and those "generally interested" in the standard. These "interest categories" are defined in Annex A of the PC MOP.

If you are interested in attending all SSPC meetings, contributing to the development of BACnet by considering or proposing changes to the standard, and serving on one or more working groups, you may obtain the application forms from the Manager of Standards.

 
SSPC Structure
 
In order to accomplish its work, the SSPC is sub-divided into a number of "working groups." Each working group is intended to address a particular issue of concern to the committee as a whole. Working groups come and go as the issues before the SSPC change. The status of the current working groups may be viewed by clicking here.
