21 REGEOCITIES_ CONCEPT SPECIFIC OBJECTIVES 1. Overcome barriers to regulation of geothermal resources & administrative procedures. 2. Identification and transferring of best practices from mature to juvenile regions 3. Make Recommendations to develop a common pre-normative framework 4. Engagement of local administration for implementing project results 5. Development of a training program focused on the target groups (administrative personnel from the cities and regions) 6. Achievement of the smart-cities concept within shallow geothermal systems Final Goal - the implementation and adoption of the project recommendations by means of the endorsed cities and regions in order to promote the GSHP and help to achieve the objectives marked in the NREAP documents

22 OBJECTIVES Stimulate the development & uptake of geothermal district heating projects In 14 EU Member States including Ireland By: Increasing awareness of the potential for deployment & applications of both geothermal energy and district heating benefits Simplifying regulations and improving national and local framework Attracting more financing Transferring best practices from mature regions Training energy officers on geothermal DH technologies.

30 Summing-Up Regulatory drivers & energy cost will continue to push the need to adopt renewable technologies. Geothermal applications offer a clean, effective solution. Improving wind energy contribution to Irish grid will lower CO 2 emission factor. Continued improvement in Ireland s electricity generation and distribution systems will reduce the Primary Energy Factor. These 2 factors will greatly enhance the importance of Ground Source Heat Pumps in reducing CO 2 emissions. GSHPs offer life-cycle cost competitive alternative to oil and LPG boilers Research into Ireland s geothermal energy potential and public support for district heating schemes will open up new opportunities for deep and shallow geothermal energy. Promotion of proven, high quality, lower life-cycle cost installations is essential. Installation of the Year competition plays an important role. GAI Conference in November Location Kilkenny.
