Abstract:
This paper deals with the conflicting goals of energy-efficient and sustainable construction. The requirements of the DGNB and BNK sustainability assessment systems are compared with the Building Energy Act. The analysis shows that there are also conflicting objectives within the sustainability criteria. In addition, there are constantly increasing demands on building efficiency and the fact that, on average, people spend more than 90 % of their time indoors. As a result, the needs of the occupants should take centre stage. The creation of synergy effects between energy efficiency, sustainability and comfort is absolutely essential. The proportion of radiant heat in any surface heating system, which has often been disregarded to date, and the design of the building to take account of these properties serve to identify synergy effects. All solutions aim to minimise the use of technology in order to prevent subsequent maintenance costs. All solutions for alternative constructions focus on dismantling and disassembly in order to fulfil the goal of a complete circular economy in the construction sector.
