3. Background: Installect Group Sustainable energy concepts & advice Groundsource (ATES) & HP systems plug en play concept 70 kW to 12 MW Production of gas engine heatpump Energy management & service To ATES en HP systems

4. Reliable systems Management RealizationConceptualization

5. Why develop a gas engine HP? >Combination with ATES systems or waste heat source >Demand for higher temperatures in commercial buildings  Central heating  Hot domestic water >Increase ATES output on heating, or decrease ATES volume >High ambitions for sustainability

6. Technological concept

11. Gasmotor >Volkswagen gasmotor >Longlife >Proven technology >Supply guaranteed

12. Compressors >Bitzer compressors >Industrial product >Proven technology >Supply guaranteed

13. Heat exchangers >Alfa-laval heat exhangers >Industrial product >Proven technology >Supply guaranteed

14. Controls >Standardized software >In house software engineers

15. Maintenance > Larger oil reservoir; > Longlife spark plugs; > Oil filters, air filters, all longlife; > Life expectancy 30.000 hours (equivalent 1,8 million Km), depending on deployment > Automatic maintenance warnings > Major maintenance at 15.000 hours;

16. Current status >18 projects realized, 3 in progress >Mechanically stable >Software fully developed >Tested for European H-gas quality >Preparing for export readiness >Elected “hottest heatpump 2014”

17. Projects & Concepts MarketProject Care Hospitals Renovation offices Datacenters Theaters In progress

18. Our approach First: make base load energy demand sustainable by: >Analyzing energy flows in production process >Analyzing energy flows in utilities  Heating  Cooling  Hot domestic water >Matching and/or buffering energy flows >Saving energy costs and exploitation costs

19. What is “sustainable” Analyzing and understanding client’s process >Reliability >Energy saving and exploitation costs during lifecycle >Integrated (overarching) approach Process is leading. Sustainability follows.

20. Project example: hospital >GW installed in central boiler room >Produces heating and domestic water instead of steamboiler >Produces cooling water instead of chiller >Simultaneous production of heating and cooling >Baseload covered >Alternatives for peak load and back-up >ROI < 3 years >PER > 3 >Combined heating & cooling for € 0,016 / kWh ! ( with gas price € 0,45/m 3 )

21. Simultaneous heating / cooling Boiler steam Chiller Gas engine Heatpump Efficiency 55%COP cooling 3,5 100% cooling 200% heating, hot domestic water 110 % natural gas181 % natural gas83% natural gas 133% heat dissipation to outside air 100% cooling 100% heating, hot domestic water Old situation PER total 0.68 New situation PER total 2,9

22. Project example: datacenter >ROI < 3 years >183.000 kg CO 2 reduction >> 50.000 m³ natural gas saved

23. Future >Export in EU >Propane as a natural coolant >Focus on higher temperatures (60 – 80) >Outdoor installation >Trigeneration (Heating, Cooling, Electricity)
