Simulations of individual-building demand where the only specified input was the annual energy demand for heating and/or cooling. Show simulations of randomly selected individual-building demand from four datasets, spanning different decades and continents: New South Wales, Australia ( g ). The coloured lines and shaded areas show modelled heating and cooling demand. The default BAIT parameters and temperature thresholds were used and P base was fixed at zero, giving an indication of model performance when given only the location of a building and its annual demand for heating and cooling, which are given in the legend. Supplementary Figs. 154–164 show simulations for a further ten randomly sampled buildings from each of the 11 building datasets used in this study. In all cases, national or building energy demand estimates could be improved if bespoke parameters were used.
