Abstract
In future low-energy buildings, electrical power and hot water use will feature prominently in the overall energy demand. Unlike space heating, these demand constituents are intermittent and vary rapidly over a few seconds. However, most building simulation tools operate at a longer time resolutions, utilising hourly climate data and so may be unable to properly capture the electrical or hot water demand characteristics. This paper demonstrates means by which electrical demand/generation and hot water draws can be modelled at higher time resolutions (1-minute) than is usually done at present. An approach to generating high-resolution climate data is also presented. An illustrative simulation highlighted different outcomes when modelling future buildings at low and high time resolutions. This showed that (in this case) although the overall energy demands and yields were similar, there discrepancies between the two temporal resolutions for import, export and self-consumption of electricity of up to 25%.
