3. What is Spatial Energy Planning?
Heat is local
Focus on a municipality/region and its heat supply and demand
Identify optimal strategies for the future
Link local renewable heat supply with demand

4. What is Spatial Energy Planning?
First step:
Know the local heat demand

5. What is Spatial Energy Planning?
Second step:
Know potential (local) heat sources – renewable and waste heat

6. What is Spatial Energy Planning?
Conclusion:
Link heat demand with supply – design optimal strategies and identify specific opportunities and measures

7. Spatial Energy Planning: Local Heat Demand
Density of heat demand
How much heat is used where?
Which customers: Residential? Industry?
What temperature levels?
What is the future heat demand?
 Crucial for rentability of district heating

8. Spatial Energy Planning: Local Heat Demand
Existing energy infrastructure
What is today’s situation of heat supply?
Existing networks for district heating and gas distribution

9. Spatial Energy Planning: Potential Heat Supply
Waste Heat
Opportunity: District heating
Spatial Energy Planning:
Identify local sources of waste heat
Are they a suitable source for district heating?
What is the heat demand in their proximity

10. Spatial Energy Planning: Potential Heat Supply
Waste Heat
Opportunity: District heating
Spatial Energy Planning:
Identify local sources of waste heat
Are they a suitable source for district heating?
What is the heat demand in their proximity

11. Spatial Energy Planning: Potential Heat Supply
Ambient Heat
Opportunity: Use ambient heat for single buildings or in district heating
Spatial Energy Planning:
Map possible sources of ambient heat: geothermal, ground water, ambient air, rivers and lakes
Identify areas where use of ambient heat is feasible

19. City of Bern: “Energiezentrale Forsthaus”
Strategic Coordination of a City’s Heat Supply

20. City of Zofingen: Heat supply from the new Hospital
Coordination of a large building project with the need of a new energy source in the old town of Zofingen

21. Municipality of Koeniz: Heat supply for a new district
Coordinating the heat supply for a newly developed district

22. Municipality of Riggisberg: Securing local heat supply
Negotiating supply and demand for district heating in a small Swiss village

23. Region of Goms: Use of regional Biogas
Use of local renewable resources and strengthening of the local economy in a region in the Swiss Alps

24. Why Spatial Energy Planning?
Opportunities and benefits
Identify and coordinate optimal strategies for the future heat supply
Seize opportunities and identify further measures: coordinate building projects with developing energy infrastructure
Improve rentability of district heating and energy infrastructure in general
Create value for the local economy and increase security of supply
Achieve environmental benefits: greenhouse gas emissions and pollution
