6 Portfolio resource efficiency bulk building materials» From waste and by-products to building materials» From building materials to building materials Asphalt to asphalt Fly ash/hifi Masonry to concrete Geopolymer Brick to brick Gypsum to gypsum

7 Propositions (2): quality, integration & target definition» Uncertainties in purity & supply secondary resources» Unknown durability new products» Potentially higher cost» Fragmented building chain» Quality control (next slide)» Integration for succesful business models (topic 3):» Function integration» Recovery of different materials at once» Chain integration, shared risk» Clear and honest targets environmental performance (topic 4):» Level resource efficiency (material, entire building, consumer...)

8 Portfolio: Quality Control» Secondary resources can be heterogeneous Quality control needed» Durability of new products unknown accelerated testing and modelling incl. uncertainties

9 » PROPOSAL: DESIGN FOR REUSE, ADAPTABILITY AND DECONSTRUCTION

10 Propositions? Flexible or long lasting, or both?» Flexible without higher material demand» Smart separation techniques: decrease building life span but increase material life span» Climate adaptive? Less restoration/refurbishment/replacement needed.+ improved energy efficiency!

11 Portfolio: dynamic and flexible design for refurbishment» Kapla Kozijn ( factory finished window)» Uitbuikmodule ( flexible design using a bulging module ) Hele flat Per 1/2 portiek Per 1/2 portiek Horizontaal Horizontaal Volledig flexibel beneden naar boven beneden naar boven boven naar beneden beneden naar boven boven naar beneden lokaal

12 Portfolio: responsive to environment (climate)» Responsive coatings» moisture sensoring just in time restoration» climate responsive (Coolcoverings, NU-roof, NIR reflective)» Adaptive insulation materials

13 » PROPOSAL: BUSINESS CONCEPTS FOR NEW AND EXISTING MATERIALS

14 Proposition: integration for successful business models» Recovery different materials at once (e.g., not only metals, also silicates)» Integrate functionalities and dare to change/expand production process» Chain integration for risk sharing and early market acceptance Submarkets building chain

15 Portfolio: integrated projects resource efficiency» SUS-CON: Multi-functional: all waste + lightweight & insulating,» Gypsum Green Deal» Sola-road, combine energy-harvesting potential with resource efficiency

16 » PROPOSAL: LEGISLATION: EU REGULATION AND TARGETS ON ENVIRONMENTAL PERFORMANCE OF PRODUCTS AND BUILDINGS

17 Propositions: reducing legislation costs through better design» Reduce complexity and effort (and decrease costs)» By adapting tools to allow for calculations by non-lca experts» By making use of available information (e.g. BIM)» By allowing estimates and including the uncertainties explicitly.» Shift focus from assessment of finalized products to assessment during the product development process» Adapt methods and tools» Deal with limited information on the product (e.g. allow for estimates)» Decrease time needed for the assessment

18 Portfolio: LCA in design & procurement» FP7 BioBuild» use biocomposite materials to reduce the embodied energy in building-façade, supporting-structure and internal-partition systems by at least 50% over current materials, with no increase in cost.» LCA as an integral part of the design process to support and evaluate decision making» Duurzaamheidskompas» a tool that can assess the sustainability of infrastructure solutions during the design phase.» Sustainability as part of tenders for infrastructure» For use both by principals and designers
