4. Summary SESAC Local stakeholders demonstrate: more sustainable local energy economy innovative approaches to energy efficiency measures: technical and business models new and refurbished buildings increased use of renewable energy (electricity, heating and cooling)

5. Partners 12 local partners from 3 advanced cities Växjö (SE): Växjö kommun, VEAB, KFAB Delft (NL): Gemeente Delft, EREA, Woonbron Grenoble (FR): Ville de Grenoble, SAGES, EDF, OPAC 38, GEG, La Métro associated partners from New Member States Kaunas City Municipality (LT) Miskolc Municipality (HU) Vastseliina Rural Municipality (EE) associations of local authorities Energie-Cités, association of European local authorities promoting a local sustainable energy policy ICLEI, Local Governments for Sustainability, European Secretariat technical partners Energy Agency for South East Sweden KTH: Royal Institute of Technology (SE)

6. Växjö City of Växjö aims at becoming free of fossil fuels • New eco-buildings with biomass district heating • Poly-generation of vehicle fuel, heat and power from biological waste • Distributed RES-cooling (absorbtion) from biomass • Demand side management: feedback

7. Grenoble New eco-buildings Biomass district heating PV at stadium and commercial buildings CHP Mini hydro 2,7 MW Energy advice in exiting buildings

8. Delft New ecobuildings: beyond Building code 2004 Refurbishment to ecobuildings at Building code 2004 level ESCO District heating from industrial residual heat

9. A short story about Woonbron Introduction of the Woonbron housing association Introduction of the Poptahof area in Delft Details about the energy measures and quality checks undertaken A short preview of the furthers steps considered

10. The 5th housing association in the Netherlands 50.000 units to let Present in Rotterdam, Spijkenisse, Dordrecht and Delft Delft

11. Seven strategic themes Co-producing with local partners Creating succesfull environments to life Creating healthy, well functioning areas Being a customer driven organisation Empowerment of the soutterain Sustainability Social investments

12. Introduction of the Poptahof area in Delft Surface area: 21.75 ha. (1 %) Population: 2,791 (128 inh./ha.) Av. househ. income € 17,130 (Delft: € 22,508) Nationalities: Dutch 37.8 % (Delft: 78.4%) Turkish 13.8 % (2.2 %) Somali 8.3 % (0.7 %) Iraqi 7.6 % (1.2 %) Moroccan 4.8 % (1.0 %) Antillean 4.1 % (1.0 %) Surinamese 3.9 % (2.0 %)

18. Details about the energy measures and quality checks undertaken, new buildings Sesac measures EPC Warmth requested controlExtra measures: EPC Building kWh / m2 not OK Installation OK Conclusions Realization

19. Details about the energy measures and quality checks undertaken, refurbishment Sesac measures Control: “cold bridges” (regulations) Extra measures air leaks, EPC not OK Ventilation OK EPC Warmth requested control Extra measures: EPC Building kWh / m2 not OK Installation OK Conclusions Realization

20. Quality control Positioned at the builders and developpers level Tests on the site for insulation (and air tightness) as early as possible Visual control by an objective expert Training for the people on site

23. Tips from the workfloor Supervise and control Discuss construction in early stage Changes in design if necessary In refurbishments there are no straight walls (note: the EU-Concerto program of which SESAC is a part, orginates in the Treaty of Lisbon, 2000, and the strategic goal of making the EU the most competitive economy in the world)

24. Further thoughts Existing heating systems may be outsourced to the heat company The on site quality checks must remain and include the ventilation units The final steps are to help the tenants improve their behaviour regarding energy Information thru feedback system, brochures and so on Interest in discussion what level of energy use is the goal, considering there are 6 more strategic themes!
