Abstract
The objective for this study was to investigate the sensitivity of model predictions of energy consumption and internal temperature to the values and algorithms for convective heat transfer coefficients at internal building surfaces employed within the dynamic thermal simulation models SERI-RES and ESP. Simulation modelling is extensively used within the Passive Solar Programme to assess the performance of designs incorporating passive solar features. The thermal simulations models SERI-RES and ESP are used for this purpose. Results from the study have shown that in terms of summer comfort assessment, the selection of any particular correlation has minimal effect. In winter, the different convective regimes would give rise to comfort level estimates that could in turn lead to different design decisions. In terms of the winter energy and plant load predictions, it can be concluded that the simulation models are highly sensitive to the choice of convective coefficients. Furthermore, ESP and SERI-RES simulations have indicated that this sensitivity is relatively unaffected for designs across a representative range. It has been observed that the predictions from time-varying correlations are within the range of those from the time-invariant cases. (author).
