Abstract:
For a climate-neutral building sector, low-tech building concepts represent a sustainable solution approach. This work therefore analyses passive, building design strategies and efficient energy concepts in order to reduce the high degree of mechanisation in office buildings and thus the energy demand. Relevant parameters for the definition of thermal comfort have been collected in advance in relation to the reference location Dresden. The thermal room simulation programme THERAKLES examines the influence of these parameters on thermal comfort and ranks them according to their influence. The simulation shows that above all monolithic, solid exterior wall constructions in combination with cascade ventilation have a positive effect on the useful energy demand. The sensitivity analysis carried out finally determines a robust preferred variant which, in addition to its favourable energy balance, can also demonstrate a good ecological balance. This work shows the energy saving potential of low-tech energy concepts in combination with passive building design measures, so that climate neutrality in the building sector can be achieved by 2050.
