Organizational Structure



Architecture Steering Committee
The Architecture Steering Committee (ASC) is responsible for ensuring ClimateTalk is a system of interoperable residential environmental infrastructure devices that share a common communications method. The committee oversees and coordinates the development of technical requirements and works with the Board of Directors to ensure the interoperability of ClimateTalk products. The committee also works with the Marketing Action Committee to develop the roadmap for ClimateTalk technology as well as the priority for its development. Working with recognized Standards Development Organizations (SDOs), the ASC will promote the adoption of ClimateTalk as an open industry standard.

Certification and Compliance Steering Committee
The Certification & Compliance Steering Committee (CCSC) is responsible for establishing requirements for the certification program and works with the board and other committees to consider all ClimateTalk Allliance requirements on the certification program. The committee defines the scope, the processes and the policies and procedures for the ClimateTalk Alliance certification program. The committee also works with the Marketing Action Committee to develop the certification branding program for ClimateTalk Alliance. The CCSC develops and maintains the test methodology, concepts, and actual test specifications, as well as processes for compliance testing and approval.

Marketing Action Committee
The Marketing Action Committee will strive to identify markets and promote ClimateTalk as an ecosystem of interoperable HVAC / Smart Grid devices sharing a common communications infrastructure. The MAC will provide recommendations and guidance on market requirements and technology trends and will work with the Board of Directors on setting the strategic direction for the Alliance. It will provide recommendations regarding how to maintain and further develop the existing ClimateTalk marketplace and advance ClimateTalk technology into new markets. Working with the Architecture Steering Committee, it will regularly review and update the ClimateTalk technology roadmap and provide recommendations to the Board of Directors regarding how the roadmap will evolve over time. The committee will provide strategy, guidance and priorities for current and future technology program development based on market needs. The Committee will build industry relationships to further the ClimateTalk brand, ecosystem and ClimateTalk Alliance strategy of expanding the number of scenarios in which ClimateTalk technology is applicable.


Under the Architecture Steering Committee

CIM Work Group
The primary responsibility of the CIM Work Group is to analyze use case applications for acceptability into the ClimateTalk Common Information Model. The CIM Working Group will follow the direction of the Architecture Steering Committee (ASC) and implement the directives and objectives received from the ASC. The CIM WG will work with each technical WG to promote awareness and understanding of the ClimateTalk Common Information Model. The CIM WG will also work with the Certification and Compliance Committee (CCC) to ensure application conformance. The CIM Working Group will develop and submit draft technical specifications to the ASC that pertain to the development and advancement of ClimateTalk applications.

CT-485 Work Group
CT-485 devices operate within a defined network structure, which covers higher level functionality such as routing, addressing and timing. The CT-485 protocol specifies packet structure and checksums and defines hardware, voltage and wiring requirements. The purpose of the CT-485 Working Group (CT-485 WG) is to focus on maintenance, development and evolution of the CT-485 protocol. The CT-485 Working Group will follow the direction of the Architecture Steering Committee (ASC), work with the Certification and Compliance Committee (CCC) to ensure device conformance, and will collaborate with other Working Groups as necessary

CT LWP Work Group
CT-LWP is the name given to what is currently being used to connect 4 wire ECM motors to indoor HVAC controls using ClimateTalk communication standards. The goals of this working group are to finalize and publish the standards in use today, identify improvements in the protocol for future applications and maintain the standard while in use.

CT Wireless Work Group
The CT-Wireless Work Group will identify and understand relevant wireless communication technologies that can support CT communications. Determine which wireless technologies are viable for ClimateTalk Communication and how CT will leverage these wireless networks. Determine how ClimateTalk CIM interfaces to/with existing wireless networks and relevant new wireless networks and protocols. Implement ClimateTalk Common Information Communication Model to wireless networks. The Wireless working group will follow the direction of the ASC work with the certification and compliance committee to ensure device conformance and interoperability

Under the Marketing Action Committee

Smart Grid Work Group
The Smart Grid Work Group is part of the Marketing Committee and is responsible for approving ClimateTalk Applications that are intended for "smart grid" applications. The SG Working Group is responsible for reviewing the smart grid application landscape and developing partnership agreements with related Standards Development Organizations (SDOs). The SG Working Group will analyze use cases to determine the feasibility of incorporation into the Common Information Model. The SG Working Group will develop white papers to provide clarification of ClimateTalk's definition of smart grid applications within the current climate of ZigBee, OpenHan, NIST, etc.
