Rolle der Digitalisierung im Gebäudebereich

Translated title: The role of digitisation in the construction sector: An analysis of possibilities, obstacles, actors and options for action.

How can energy efficiency and the increased use of renewables in residential and non-residential buildings be increased with the help of digitisation? The authors of this comprehensive analysis have pursued this question and have identified and evaluated potential options.

In the first part of the study, a number of applications are described and their contribution to increasing energy efficiency and the use of renewables is assessed. The cases considered include housing stock and cover two major subject areas:

1. digital tools for the planning, construction and functioning of energy-efficient buildings (BIM)
2. increasing energy efficiency through information and communication technology

Through this, variable and fixed costs as well as the necessary degree of automation in building processes are also considered. From this evaluation, the number of application options for the three building types considered single and two-family buildings (EFH/ZFH), multi-storey residential buildings (GWB) and non-residential buildings (NWG)) could be reduced to the following five:

1. industrial redevelopment with BIM in multi-storey residential buildings, taking BIM planning into account, 
2. improving maintenance procedures for renewable energy systems for heating in non-residential buildings, taking the potential of multi-storey residential buildings into account, 
3. optimisation of renewables usage in single or double apartments, taking into account rental-living and usage in multi-storey residential buildings and
4. increasing energy efficiency through transparency in single and double apartments and in multi-storey residential buildings.
5. increasing energy efficiency through controlling the consumption of non-residential buildings 

For these five applications, barriers and gaps were then identified and assessed for their severity and potential for being overcome. The obstacles of greatest importance that also had potential to be overcome were analysed in further detail. In order to move from describing of the problem to developing solutions, the next step was to develop solutions to the obstacles and gaps and to discuss them with stakeholders. At the end of the study, recommendations for action were developed from the analyses and from exchanging with experts and stakeholders, who could refer to specific measures for in-depth examination.
