Green Building Certification Optimizer (2D)

Rating systems like LEED and BREEAM score a building across categories — energy performance, water efficiency, materials, indoor air quality, site design and innovation — and add the points up into a certification tier. This 2D simulator lets you allocate a limited construction budget across six such categories, each with its own diminishing-returns cost curve, and watch six flat bar towers rise in real time on a pannable, zoomable chart as the design accumulates credits. Live readouts track total points, spend against your budget cap, and which tier — Certified, Silver, Gold or Platinum — the design currently clears, making the real economic trade-off of chasing certification points tangible.
