Boiler Management Systems

Where a sophisticated Building Management System is installed at great expense by an expert systems programmer there is an 'efficiency gap' in the control strategies of such systems. Boilers, in principle, need to provide the correct amount of heat energy to balance building heat losses and gains under given set point and weather conditions.

What is not understood is that 'state of the art' installed building controls - even those produced and sometimes maintained by prominent global suppliers such as Siemens, Honeywell (Trend) and Johnson - are falling short of the ability to dynamically balance building heat gains and losses through their currently embedded or programmed control strategies.

The two main contributors to heat wastage in buildings, whether poorly or well controlled, are:

Boiler set-point temperatures are nearly always unnecessarily high even if compensated for demand.

Control decisions to change boiler temperatures, sequencing or the mixing of primary temperatures to achieve lower secondary temperatures are made as a result of inside and outside temperature differences and not building heat losses and gains. Every building has its own heat transfer profile and heat "inflows" have to be dynamically reconciled with "outflows" for good energy
