Abstract

This paper aims to investigate the impact of future climate on building systems, taking account of a strict building standard. A building is modelled in TRNSYS regarding a sustainable heating and cooling energy production by solar heating and radiative cooling in combination with water storage tanks. Sensitivity analyses (Morris Method) are performed for the technical building configurations for the years 2030, 2050 and 2100 (REMO climate model). They are compared and evaluated with the current reference climate (TRY) of 2017. The objective is to show which components have a significant influence on the energy consumption of buildings. Furthermore, due to the climate change sustainable building technologies are necessary. This paper demonstrates how the influence of the climate can be counteracted from the perspective of building services. Global warming requires a rethink of the interaction between building design, building technologies and climate. In this point building services engineering offers the most flexibility. By performing parameter studies, early knowledge about the building and its required technology can be gained. The target value of this study is the indoor air temperature as a function of the outdoor temperature. The objective function corresponds to specifications according to the European standard EN 15251. Following the parameter studies, optimization processes are carried out.
