capacity expansion 3 80 - 100% nutrient recovery an interested research institute. This step is not critical to the overall functioning of the neighborhood, but is desireable because it will lead to a more closed material cycle overall. 4 electric mobility capacity sible for the community to self-sufficiently supply its energy needs. An investment in additional solar panels would support the community’s driving habit. COST & LABOR ESTIMATES Installing electric charge points is currently incentivized by various government programs and subsidies. As such, we anticipate that it will be possible to install electric charging stations for free at the Schoonschip site. Producing sufficient electricity to fully power the electric vehicles owned by Schoonschip residents will approximately double the electricity demand of the neighborhood if residents drive roughly as much as average Dutch citizens do. This is an important consideration when scaling the solar system. The nutrient recovery system can be upgraded by adding an aglae bioreactor to the D-SARR digestion system. The bioreactor will harvest nitrogen from waste streams for use in on-site food production. COST & LABOR ESTIMATES The cost of adding a bioreactor unit to the D-SARR system that can successfully harvest nitrates for local agriculture highly depends on the type of technology that is ultimately chosen. We recommend implementing this on the Schoonschip site as a pilot by partnering with An electric car sharing system should be implement consistent with community demand. The system can be linked to a community management platform, allowing individuals to see when cars are not available and to block out when they plan to use one. As a community, the group can decide if they want to purchase solar panels for charging car batteries. The electricity required for charging a vehicle with average use is equal to an entire household’s domestic electricity consumption. Using an electric car sharing system will be equivalent to doubling the number of households. Without solar panels, it will not be pos86 / 146 Pagina 85
