Proposed new HVAC Systems Group (subject to approval by the CIBSE Board)


This proposed CIBSE Special Interest Group (SIG) for HVAC Systems will enable specialists in this area to share ideas and knowledge on the design, installation and operation of heating, ventilation and air-conditioning systems. HVAC systems are widely used and yet still there is much we do not know or understand about their use, operation and performance, from fluid flow dynamics within some boiler systems, to part-load control and operation issues to deliver acceptable thermal comfort conditions, to indoor air quality related to outdoor air quality. The proposed Group will provide a focus to inform, to share and promote best practice, debate current issues and problems, disseminate guidance, encourage continuous improvement and help deliver better performance for building users, and other stakeholders.

Integration and Liaison

The proposed group will liaise and work closely with ILEVE (the Institute of Local Exhaust Ventilation Engineers), and with other relevant Special Interest Groups (such as Energy Performance, Facilities Management, Natural Ventilation, Intelligent Buildings etc), to complement, support and strengthen the work they do where appropriate.  Representatives from ILEVE and from the other SIGs will be invited to join the Group steering committee, and the proposed Group will establish clear lines of communication.  In addition, the proposed Group will seek to work with the CIBSE BIM Group, as well as liaising with CIBSE Committees (such as Knowledge Management) where invited to do so.


As with other SIGs, this group will provide

  • Regular news through email and social media
  • A webpage to inform and provide support
  • A forum covering key aspects of HVAC System performance and operation
  • Workshops, technical meetings and debates on key topical HVAC Systems issues

Draft Terms of Reference

  • to broaden knowledge and awareness of the strategic and practical issues, the latest developments and new technologies related to HVAC systems
  • to act as a specialist forum for knowledge exchange about best practice and lessons learnt, and to increase members'  knowledge and skills in the HVAC specialist area
  • to identify knowledge gaps relating to the design and operation of HVAC systems, and promote appropriate research in these areas
  • to contribute to the development of new publications and the maintenance and updating of existing guidance
  • to seek collaboration and links with other relevant institutions and organisations
  • to provide speakers for events, technical papers, seminars and training courses, and to organise a programme of events as appropriate

Members are welcome to support or comment on the proposed group by emailing by Monday 20 March.
