Notice of Staff Workshop on
Programmable Communicating Thermostat (PCT)
Systems Integration Framework

The California Energy Commission's Public Energy Interest Research (PIER) Program will host a public workshop to hear comments from thermostat manufacturers to support the current Title 24 Building Standards for Energy Efficiency specifications for the programmable communicating thermostat (PCT). Participants will address ways to better integrate PCT systems, as proposed at a previous workshop.

The workshop will be held:

Thursday, FEBRUARY 16, 2006
10 a.m. to 4:00 p.m.
1500 Eleventh Street
First Floor, Auditorium
Sacramento, California
(Located two blocks from the CALIFORNIA ENERGY COMMISSION)

This workshop is the third in a series of discussions on developing an integrated framework for demand responsive systems. The first workshop, held February 1, 2005, examined the best ways to exchange information by establishing common points of reference. The second, held November 29, 2005, dealt with PCT integration issues. This workshop will address the widespread deployment of PCTs from a vendor's point of view. Thermostat manufacturers and others will evaluate different options for deploying PCTs and their supporting infrastructure, such as the number of units needed, their cost, their commercial viability, and the time frame needed to put them in place.


System integration uses standardized interfaces to link together software and hardware components for different vendors. The goal is to:

  • Encourage "open architecture," a common understanding that allows information generated in one vendor's product to be read by another vendor's products. Using a common language encourages innovation and lower costs.
  • Decide on all the potential functions that supporting infrastructure should perform. Such pre-planning lowers costs by minimizing obsolescence and reducing the likelihood of stranded assets.
