Abstract

The objective of this study is to investigate and assess the energy flexibility performance of typical Danish office buildings constructed at different periods. Four building study cases have been compared with different heating demands, structural thermal masses, envelope insulation levels and infiltration rates. All cases are equipped with the same novel two-pipe heating and cooling system. Each case is divided in four subcases with variations of heat gains: people load, lighting load, equipment load, solar gain. Analyses and comparisons have been performed on different parameters, including power load shifting and grid adjustment, comfort level, and economical benefits. All investigated cases are tested with two control strategies: a normal reference control strategy and an energy flexibility control. The flexible controller adjusts the indoor temperature set points for heating and cooling depending on different energy price levels.
