10. Mobility main issue after heating Next to Marburg, shuttle traffic, distance 12 km Also: railway station: 6km  Ideal for E-bikes!  Need for bike boxes against theft and whether  App for reserving and checking availability  Can build on carsharing community and service 2014-11-25A roadmap to energy efficient community-different approaches,the same aim10 Different Approaches and Measures - Cölbe www.coelbe.de

11. Aim for CO2 neutrality in 2035 Need for building renovation: 3% or more Acutally achieved through funding programm (ended) Two quarter concepts. Goal: 5-6% by  Quarter manager will actively consulate citizens/house owners  Offer: contract with renovation roadmap with 5-6% grant Niestetal 2014-11-25A roadmap to energy efficient community-different approaches,the same aim11 www.niestetal.de

12. Quarter concepts  Extension district heating  Demografic affairs  Street renovation  E-mobility  Change of housing association – chance for new impuls Barrier free Tailoring of the apartments LED in street lighting, 10-20% per year Baunatal 2014-11-25A roadmap to energy efficient community-different approaches,the same aim12 www.baunatal.de

13. Recommended actions:  Energetic renovationof buildings  Change of behaviour  exchange of devices  Exchange of old heating systems with more efficent ones  Subsidies for RES plants Prusice 2014-11-25A roadmap to energy efficient community-different approaches,the same aim13 www.prusice.pl

14. Advanced Strategic Energy Planning & Energy management  EPC and ESKO projects  Energy project buffer  Smart Meetering E-mobility  Public transport fully electrical  City Police Statutory City of Opava 2014-11-25A roadmap to energy efficient community-different approaches,the same aim14

15. Projects Examples  PV system on primary schools and public buildings Pilot project „Šrámkova primary school“  Biomass production Cultivation of fast-growing trees on City grounds Use of biomass from city parks and green areas  Complex building renovations Mainly Primary schools Statutory City of Opava 2014-11-25A roadmap to energy efficient community-different approaches,the same aim15

16. Duplek 2014-11-25A roadmap to energy efficient community-different approaches,the same aim16 Sector households:  Largest Energy efficiency/savings potential  Good potential for energy efficiency cooperatives, local/ national incentives; Sector industry: undeveloped – largest potentials in electricity; Public sector: highest potential in public lighting and thermo-modernization; Traffic: next to biggest city of the region – Maribor; advocating use of sustainable mobility solutions (e-mobility, mobility on demand, alternative transport modes); www.duplek.si
