S.winter eco and energy-efficient wood constructions

  1. 1. Eco- and Energy-efficient wood constructions Univ.-Prof. Dr.-Ing. Stefan Winter FiDiPro Professorship Aalto University
  2. 2. Energy and resource efficiency is the leading condition to reach a real sustainable economy based on oil, gas and coal independent energy supply!
  3. 3. What are the possibilitiesand the responsibilities of the Building Sector? Univ.-Prof. Dr.-Ing. Stefan Winter FiDiPro Professorship Aalto University
  4. 4. Increase energy- and resource-efficiency in the building sector... Faktor 10 Heat-energy consumption
  5. 5. ...by renovation of the existing building stock...
  6. 6. ...and new low-energy, passive- house or even Plus-Energy buildings...
  7. 7. ...with proved carbon footprint etc. WOOD IN CARBON EFFICIENT CONSTRUCTION
  8. 8. Is timber able to help to generate solutions?
  9. 9. YES !+ Sustainable Material+ carbon storage+ low thermal conductivity+ moisture buffering+ high heat capacity+ excellent weight-to-strength ratio+ embedded energy+ high recycling potentialetc., Univ.-Prof. Dr.-Ing. Stefan Winter FiDiPro Professorship Aalto University
  10. 10. What do we need to fulfill the eco-efficiencyrequirements with timber structures? Univ.-Prof. Dr.-Ing. Stefan Winter FiDiPro Professorship Aalto University
  11. 11. + Well trained designer and practice+ Building physics best practice+ Prefabrication and Quality Management+ Customer oriented offers+ Cooperation with concrete industry+ Adequate offers from woodworking industry+ Research & Development+ Political support.... Univ.-Prof. Dr.-Ing. Stefan Winter FiDiPro Professorship Aalto University
  12. 12. Some examples:
  13. 13. Dry structures – No mould! The three most important reasons+ Built-in moisture due to wet buildingmaterials and wetting during erection++ Convection+++ Driving rainlow-2-no - Diffusion
  14. 14. How to avoid?Accurate detailing andsecond defense lines!No need to „re-invent“ everything again!
  15. 15. Test Houses in Otaniemi FiDiPro Prof. Stefan Winter Energy Efficient Timber Houses and Areas
  16. 16. Data acquisition walls Temperature and absolute humidity profiles in the North wall of the gypsum board test house (mineral wool insulation; moisture variable vapour barrier) Temperature and relative humidity profiles in the North wall of the plywood and gypsum board test houses (mineral wool insulation) FiDiPro Prof. Stefan Winter Energy Efficient Timber Houses and Areas
