Analysis and implementation of operational flexibility of energy supply systems within non-residential buildings

Copyright: EBC Analysis of flexibility potential

Non-residential buildings that use heat pumps and air-handling units (AHU) for their thermal energy supply can be utilized to offer grid services in form of energy flexibility. The flexibility potential within such non-residential buildings lies within the redundancy of thermal energy provision. The building’s energy demand can be met using either gas as input energy for the AHU or electricity for the heat pumps. Furthermore, the indoor climate can be altered and temperatures varied. Changing the indoor temperature yields a change in energy consumption and can be applied within the temperature boundaries that occupants perceive as acceptable.

A model of the building was created for the evaluation of these flexibility potentials and simulation purposes. The applied modeling approach uses neural networks to calculate the energy demand under a given set of weather conditions, occupational schedules as well as indoor temperature and set points.
