Abstract:
Energy saving potential of adaptive façade elements for local heating – a parameter study The working world has been changing in recent decades. Nowadays, many offices, meeting rooms but also other rooms, such as lecture halls, classrooms and hotel rooms, are only used temporarily. However, thermal conditioning is still based on temperature baselines in steady state. This means that a corresponding set temperature must be reached before the user arrives in the room and must be maintained for the entire working period, regardless of the presence of the user. Adaptive facade with integrated heating or cooling elements is able to adapt to changing conditions, i.e. due to temporary use of a workplace, locally and without time delay and thus ensures an optimal quality of stay. Furthermore, a significantly lower temperature level is sufficient during the heating period. As soon as the user arrives in the room, comfortable conditions can be created immediately by switching on the local heating system. This holds a great potential for energy saving, especially in ultra‐lightweight construction. In previous investigations, the thermal comfort under transient conditions [1] was illuminated and the building physical functionality and environmental impact of some examples of adaptive lightweight structures [2, 3] at building component and room level were discussed. Based on these findings, scenarios for the operation of adaptive facade elements with local heating systems were developed. In this present article, the energy saving potential of the local systems is compared to conventional heating.
