Introduction of the Dubbelbeek project
• Research question:
• Project boundaries:− Social payback time of 15 years− Building has to be zero energy on annual basis− The building does not have to operate autonomously− The existing building concept has to be used− The electricity used for the cars is not part of the zero energy balance
PAGE 413-04-2023
“How to make the building Dubbelbeek annually energy neutral with integration of the possibility to charge 100 electric cars?”

1. Saving energy
Passive adjustments:
• Rc-value change• Solar gain factor• Shadow factor• Heat recovery
• Ventilation air• Shower heat recovery
• Using LED’s

Trias Energetica
2. Renewable Energy
• Wind energy• Small scale (to low yield vs. cost, required area, wind speed)• Large scale (to low wind speed on the site)
• Solar energy• Photovoltaic (applied at the parking lot)• PV-twins (applied on the roof)
• Hydropower (not viable option near the location)
• Geothermal (ground is possible for geothermal)

Trias Energetica
3. Active systems
• Heat pump with Aquifer Thermal energy storage (ATES)
• Combined heat and Power (CHP)• With wood pellets

Concept
PAGE 1513-04-2023
Space heating (peak load)• 80% Aquifer Thermal Energy Storage system• 20% Combined Heat and Power
Space cooling (peak load)• Direct cooling out of the aquifer
Hot tap water demand• < 40oC Aquifer Thermal Energy Storage• < 65oC PV-twins• Extra Combined Heat and Power
ATES system designed at cooling load. The extra heat is in the philosophy of integration sold at the nearby swimmingpool (aprox. 150m)

Conclusion
• 100 % energy neutrality is not met• 89 % without wood pellet CHP• 93 % with wood pellet CHP• 100% with imported ‘green electricity’
• Social payback period of 15 years is feasible
• Passive solutions lead to a significant demand reduction of 51 %
• Balancing the ATES system: Look to district level
• Implementing electric charging points requires smart design: • Extra transformer, placement of the PV-panels

Discussion
- Orientation and location were pre-determined, as well as the shape of the building
- Hardly any accurate information of the building available
- Integrated design is somewhat simplified to calculate the annual energy balance
- Technical and economical feasibility of the construction with the aqua centre has to be investigated in more detail
- Financial analysis based on well-substantiated estimations:- Lack of information (no offers from companies)- Influence of several subsidies hard to identify- Focus on applied systems
