Efficiency is in the spotlight as never before due to a huge rise in electricity and gas prices. As worsening climate change also makes clear, without intelligently-linked systems in buildings it will be difficult to plan and build for the future. The basis for such systems is smart technology, which significantly helps save energy and reduce organisational effort. As a result, climate targets can also be more easily achieved through lower energy consumption. The connection with building automation is proven, for example, by a study published in 2021 by the industry association Bitkom. According to the study, up to 14.7 million tonnes of CO2 emissions could be saved by 2030 through the use of building automation – if used across the board. This corresponds to almost 30 % of the reduction target for the building sector set out in the Climate Protection Act. There is therefore still a lot of catching-up potential, especially since the Bitkom study estimates that just 3 % of all residential buildings are equipped with building automation. For non-residential buildings, the figure is 28 %.
