"Building - how much technology does climate protection need?"​​​​​​​
Buildings and their operation are among the main sources of climate-damaging emissions. The emissions have a serious impact on the global climate and its warming. In addition to the construction of buildings, a significant part is caused by the generation of heat or the cooling of buildings, since it is still mainly fossil fuels that are at the beginning of the energy chains.

These correlations have been known for decades. Minimising emissions during energy transformation, for example through the direct use of solar energy or geothermal energy, has so far only been possible to a very limited extent. Instead, regulations to minimise energy consumption have been continuously strengthened over the past decades. As a result, building has changed dramatically. Buildings are being highly thermally insulated with considerable structural effort, for example through multi-layered constructions of the building envelope or through the use of high-tech materials. The result is a considerable increase in constructional and financial expenditure in the building process. But thermal insulation alone is often not enough to achieve the desired reduction in emissions. Additional building technology, for example for artificial ventilation with heat recovery, has established itself as a standard in construction. The share of costs for technical building equipment of the total building costs is increasing significantly.

We want to discuss to what extent climate protection has to rely on the described technical expenditure in building. Are there alternative strategies and ways? Can climate protection in building only be achieved with the help of complex and costly construction and building services engineering? Can this valid strategy of the industrial nations for achieving climate goals be transferred to all regions worldwide? How does the high proportion of technology affect the energy balances? And last but not least, what effect does the effort described have on architectural quality?
