Whitepaper: Serial renovation – cost reductions, efficiency gains and new industry structures through industrial prefabrication in refurbishment<\/h1>\n

[\/vc_column_text][vc_single_image image=”16″ img_size=”full”][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/3″][vc_column_text css=”” el_class=”h8″]Our new whitepaper, which we produced together with the consultancy eco2nomy, shows that serial renovation offers considerable potential for reducing costs and increasing efficiency.[\/vc_column_text][\/vc_column][vc_column width=”2\/3″][vc_column_text css=””]<\/p>\n

As part of the climate targets for the building sector, more than 70% of multi-family homes in Germany must be renovated to make them energy-efficient by 2045 in order to achieve climate neutrality.<\/h6>\n

Serial renovation as the key to climate neutrality<\/h3>\n

The whitepaper emphasizes that serial renovation must play a central role in achieving the goal of climate neutrality in the building sector. \u201cWithout industrial prefabrication and optimized construction processes, we will not be able to achieve the necessary renovation rate,\u201d says Dr. Martin Handschuh, industry expert at eco2nomy. \u201cSerial renovation enables a more efficient and cost-effective renovation, which is essential in ight of the shortage of skilled workers and low productivity in the construction industry.\u201d<\/h6>\n
According to the study’s calculations, heating systems or district heating connections will need to be replaced in over 70% of apartment buildings by 2045. In addition, more than 60% of buildings will require insulation measures and the replacement of building envelope components. This requires an annual renovation rate of 3%, which would be achievable achievable through serial renovation in a realistic scenario.<\/h6>\n

20% cost savings through serial renovation<\/h3>\n

Compared to conventional renovation processes, up to 20% of costs can be saved through serial prefabrication. This is achieved by shifting the work to standardized, industrial value-added stages such as planning, prefabrication and logistics. \u201cPrefabrication significantly reduces construction site costs and increases productivity through industrial economies of scale without the need for more tradespeople,\u201d explains Dr. Constantin Greiner, construction expert at Munich Strategy.<\/h6>\n

Up to 120,000 residential units per year could be renovated serially<\/h3>\n

The analysis also shows that buildings with up to 120,000 residential units in Germany could be renovated serially every year. The focus here is on unrenovated apartment buildings from the 1950s to 1970s, which are particularly suitable for serial renovation due to their design. The criteria for suitability are, for example, a living space of over 1,000 square meters, a number of storeys between two and eight, simple cubatures and fa\u00e7ade structures as well as easy access to the property. Around 20% of buildings meet the criteria, which corresponds to a potential of 10,000 to 15,000 apartment buildings with up to 120,000 residential units per year.<\/h6>\n

Clients only partially satisfied with renovation specialists<\/h3>\n

The whitepaper points out that the renovation specialists in pilot projects have so far only partially met the expectations of clients. \u201cThere is potential for optimization both in terms of the design of offers and prices as well as in terms of interaction with customers. It is important to offer customer transparency so they can make good and well-considered decisions,\u201d says Dr. Martin Handschuh. Better coordination between real estate companies, manufacturers and refurbishment specialists will therefore be crucial in order to exploit the full potential of serial renovation.<\/h6>\n
Dr. Constantin Greiner underlines the importance of service integration: \u201cOnly if all parties involved work together in an integrated process can we realize the efficiency gains.\u201d Such an ecosystem enables interface-reduced work, clear responsibilities and learning effects that lead to further optimization of the renovation process.<\/h6>\n

Der Handel ist am pessimistischsten<\/h3>\n

Am schlechtesten bewertet der Handel seine gegenw\u00e4rtige Lage: Neun von zehn Handelsh\u00e4usern sagen, dass sich ihre Gesch\u00e4ftslage 2023 verschlechtert hat. Immerhin 65 Prozent geht auch f\u00fcr 2024 von einer nachlassenden Nachfrage aus. Der Anteil der ertrags- und finanzstarken Akteure im Handel hat sich bereits seit 2022 reduziert. Munich Strategy erwartet, dass 2024 \u00dcbernahmen und Gesch\u00e4ftsaufgaben die Konzentration im
\nHandel verst\u00e4rken werden.

Globale Investoren setzen auf Bausoftware<\/h3>\n

Die aktuelle Krise am Bau und der Druck zur Effizienzsteigerung f\u00fchren zu einem zunehmenden Interesse an Bausoftware. Das zeigt der Munich Strategy Construction Index, der die Entwicklung von \u00fcber 100 b\u00f6rsennotierten H\u00e4ndlern, Herstellern und Dienstleistern der Baubranche weltweit abbildet. Die Aktienkurse der Unternehmen, die sich auf Software f\u00fcr die Bauindustrie spezialisieren, verzeichnen ein deutlich h\u00f6heres Wachstum als die der anderen Bausegmente. Seit Anfang 2000 wuchsen die Aktienkurse der Bausoftware-Unternehmen mit j\u00e4hrlich 14,6 Prozent (CAGR), w\u00e4hrend der Handel mit 8,6 Prozent, die Bauausf\u00fchrung mit 4,5 Prozent und die Baustoffindustrie mit 3,5 Prozent p.a. wesentlich langsamer an Wert zulegten.<\/h6>\n
