3 Background and Danish context 20: EU-Directive 20/91/EC - energy performance of buildings 2008: Danish building code adopts EU-Directive - regulations for energy consumption of buildings 21: low-energy classes 25 and 20 are announced to provide a roadmap for future legal guidelines to the construction industry 30% of the Danish energy consumption can be related to households SBI1 on energy focussed renovation: 73% potential energy savings in the existing building stock Danish building stock: app. 30% of all multi-storey residential buildings have been built between and are awaiting renovation in the near future SBI - Danish Building Research Institute. Figures from report SBi 20:56 Statistical data form DST (Statistics Denmark) 20/11 1 Sustainable Innovation 22 / Alanus University, Bonn /

4 Market potential for renovation of multi-storey residential buildings in Denmark 56,6 years is the average age of a building in Denmark in 21 61,5% of all residential buildings are older than 40 years 24,5% of all residential buildings are older than 80 years 33% of the Danish building stock was built between 1950 and 1975 (montagebyggeri) 1,3% of the Danish building stock was built after the new energy regulations came into effect (BR08) Source: Calculations based on figures from DST (Statistics Denmark), 20/11 Sustainable Innovation 22 / Alanus University, Bonn /

7 Case studies Political perspective The subsidized housing sector should be pioneering construction, and ensure the achievement of the highest quality for the best price, not only in respect to technical and functional qualities, but also qualities such as architecture, accessibility and the minimizing of environmental impacts related to construction. Owners of subsidized housing units should through their building activity help to develop the building sector, help to build-up new skills and promote the new industrialisation of the construction industry. translated from: Byggeriets Fremtid fra tradition til innovation (The Danish Agency for Trade and Industry (EFS) 2000, p.67) Sustainable Innovation 22 / Alanus University, Bonn /

8 Case studies Urbanplanen, Copenhagen ( ) Rækkehusene, Brøndby Strand ( ) Heimdalsbej, Frederikssund (20 - ) Fælledgården, Copenhagen (20-12) before renovation during/after renovation Sustainable Innovation 22 / Alanus University, Bonn /

9 Case studies Client requests Clients from the public sector demand: economic security (construction + operation) high workmanship quality (-> less defects) least inconveniences for their tenants during the construction period energy savings during operation phase (-> economy) lifetimes of building components of at least 30 years (-> economy) Sustainable Innovation 22 / Alanus University, Bonn /

14 Integrated Product Deliveries (IPD) 1. Modules with a specified function and specified interfaces to other modules 2. Producer offers product configuration (mass customization) 3. Production in an industrial context, allowing higher quality at lower costs (possibly prefabrication) 4. Services can/should be included (e.g. planning support, assembly, maintenance) $ 5. The IPD offers a solution for a certain need in a building project (e.g. interior climate solution) Advantage: Reduction / integration of complexity of building products, components and services?

16 Sustainable Integrated Product Deliveries Sustainability has not been a key parameter in the development of recent IPDs but, use of low-maintenance and/or certified materials (e.g. altan.dk) reduction of material use and efficient production in factories (e.g. NCC shaft) focus on working environment at the production facilities Source: Beim, A., J.

17 Sustainable Integrated Product Deliveries 1 sustainable by design: material choice, production method, longevity / robustness potential for recycling/reuse 2 sustainable through operation: use of the IPD increases the sustainabilty of a building project e.g. use of sustainable materials to reduce initial environmental impacts socially responsible production optimal lifetimes for product purposes reuse / recycling concepts and guarantee e.g. technical solutions to reduce energy consumption systems that allow easy adaption / use change service that affects user behaviour Sustainable Innovation 22 / Alanus University, Bonn /

20 Extending IPDs towards Product Service Systems (PSS) The sale of products does not encourage a closed cycle economy because at the point-of-sale the responsibility for the user phase and the disposal is transferred to the customer; it is the customer who decides what is to happen to the product after use. The sale provides no incentive for the manufacturer to supply goods, which have a long life or are reusable.

21 Extending IPDs towards Product Service Systems (PSS) raw material extraction production construction use + maintenance end-of-life SYSTEM SUPPLIER / SYSTEM OWNER The system supplier controls all life cycle stages, from production to end-of-life sourcing of greater amounts of raw materials allows upstream influence or reuse of materials will lower the necessary new, raw material input Clients are offered a one-stop solution for the construction project and maintenance during the use stage, as well as greater economic confidence in building and maintenance costs -> a building solution can be offered challenges for system suppliers in the building branch: great uncertainty caused by long life cycle (50 years + ) low value of building materials -> low incentive for remanufacturing / re-use / recycling legal issues concerning ownership of building components legal issues with ownership of product-related rights -> open system?
