There is excellent guidance from CIBSE, BSRIA, etc. on many aspects of building services. However there is very little guidance on controllability and control strategies necessary for modern plant
and bivalent systems.
Recent CIBSE guidance includes the following:
BSRIA control strategies and CIBSE Guide H have not been updated in recent years to include relevant issues. The Building Regulations Part L and associated guidance has limited controls guidance and some of this is simplistic and potentially confusing IMHO.
Most building services engineers have a limited understanding of controllability and control strategies necessary for modern systems. Most control systems integrators have a limited understanding of building services, particularly the effects of different hydraulic arrangements on control strategies. What is needed is better understanding between the different disciplines of all issues relevant to a successful controllable system.
BRECSU General Information Report 40 Heating systems and their control endeavoured to bridge this knowledge gap and was produced to accompany a series of seminars across the UK including many CIBSE regional events. However, GIR40 is now out of date and despite the increasing complexity of systems there has been limited guidance in intervening years on overall system design and controllability.
