Stroma Tech’s heat loss and heat gain calculations can help designers to deliver intelligent building services designs, with heating and cooling systems that optimise occupier comfort, in the most efficient way.
Working within the best practice procedures established by the Chartered Institute of Building Services Engineers (CIBSE), we use IES dynamic thermal modelling software to provide the designer with peak simultaneous loads and internal zone loads for plant and emitter sizing.
Heating load calculations are based on a steady-state scenario for internal set-point and external ambient temperatures. The calculation incorporates conduction, convection, radiation and inter-zone energy transfer. Thermal gains from solar radiation and internal activities are ignored, to represent building start-up conditions.
Cooling load calculations are based upon the CIBSE admittance method and include the effects of casual, occupancy and solar gains. The simulation repeats over a number of days to allow convergence at the average peak conditions, considering the same energy transfer processes as a heating load assessment.
Results of this exercise will show the impact of each heat gain component in turn, providing designers with a hierarchy of areas to review for plant size reduction.
