Heat Flexibility as A Function of The Outdoor Climate: A Study of Danish Dwellings.
Abstract
To limit the need for peak load heat plants and to reduce greenhouse gas emission in district heating grids, we investigated the heat flexibility of different buildings in Denmark and how district heating grids can be better utilized. In this study, the flexibility of Danish residential dwellings from different time periods was modelled using the TABULA database. The thermal response of these dwellings was simulated for each day of the entire heating season and daily heat flexibility was calculated and analysed statistically. As a result, daily heat flexibility was formulated as a function of outdoor temperature and solar irradiance. This way, heat flexibility can be used in practice based on weather forecasts.
