Description of different experiences with sustainable housing in Denmark

1. Sustainable housing - strategies for existing and new buildings based on 25 years of experiences and visions from Denmark Associate Professor and Science Shop co-ordinator Michael Søgaard Jørgensen Department of Management Engineering Technical University of Denmark, 2800 Kgs. Lyngby, Denmark E-mail: [email_address]

10. During the 1990s: A few demonstration projects in Copenhagen with combination of quality and environmental refurbishment Financed by urban renewal funds Hestestaldskarreen in the Western part of the city center 15 different houses with their own resident board Developed project to gether with municipal adviser Plan. Not all was implemented

11. Solar cells on some of the walls. Covering a small part of the energy consumption: for the common lighting in the court yard and for the regulation and pumps in the energy and water system Constructing the joint rain water collection tanks. Used for flushing the toilets. Not all houses use the system Common technical system for regulating heat and water

13. Refurbishment of one-family house from 1970s: Insulation of facade, foundation and loft Renovation of part of the roof Renovation and change of windows and external doors Change of gas boiler Installing ventilation system (with re-use of energy!?) No results yet, but investments are substantial Need to be combined with (planned) renovation Thermography – a new tool in the identification of energy renovation needs Building component companies engage in experiments: looking for new market opportunities

15. Integration of renewable energy in buildings Thermal solar energy for heating: 50% on houses 50% on heat and power plant buildings

16. Need for tailor-made energy renovation concepts: Energy refurbishment of private semi-detached houses Energy renovation concepts need to fit to the technical and social aspects of the buildings and their infrastructure

18. Co-operative housing: Also a challenge Limits to rent. Residential democracy. Lack of funding

19. Kirsten Gram-Hanssen, SBI- AaU Big differences in energy consumption in same type of houses Electricity: The bigger household – the higher total consumption But lower consumption per person Big differences: - Those that like to save - Those that like to consume Heating: Type of house important User habits important Young and elderly persons use the most

23. One of the types of eco-labelled houses The area where the houses are built or planned to be built

24. Website organised by the local Agenda21 center which initiated the project

32. CO2 pyramid for food ingredient choice Lavet af: Philip Giødesen Lund og Lars Krogsgaard Madsen i samarbejde med Videnskabsbutikken, DTU Food items

33. Assessing 10 recipes for heart healthy menus: often also climate friendly Projekt lavet af Kenneth Barnett, Derek Eggiman, Jesse Sawyer, WPI på DTU

35. The (urban) company in context: Four types of corporate network relations Product chain: The daily flows of information, capital and material resources In the city Maybe also in the city Local network 1: Workforce, supply, local regulation etc. Supplier A Supplier B Customer1 Regulatory network X: Government, civil society organization etc. Regulatory network 1: Government, civil society organization etc. Local network X: Workforce, supply, local regulation etc. Company Developmental network: Here also involving supplier and customer Final user

37. Civil society protests against the big consumption of coal used for energy in Denmark. Windturbines cover only around 20% of the electricity production Phasing in renewable energy means phasing out non-renewable energy

38. Smart grid – a new buzz word within energy production and consumption
