Assess students' ability to design a complete, realistic sustainable mini‑community for 50 residents on a 2‑hectare plot. The task requires specification and justification of: energy systems with clear calculations (daily kWh demand, solar/wind sizing, battery/storage and backup), food and water supply plans with area/yield and volume/storage computations (garden yields, rainwater catchment, storage needs), waste management and recycling strategies (composting, graywater, landfill reduction), low‑impact transportation options, an itemized estimated budget, and a one‑page persuasive justification. Require stated assumptions and all supporting calculations.
