Real building-certification schemes like LEED award a fixed pool of points per category, and a project's percentage progress in each category determines how many of those points it banks. This scorecard mirrors that: each slider is the share of the available measures actually implemented in that category (insulation upgrades, low-flow fixtures, recycled/local materials, daylighting and site restoration), and the category's point pool scales by that share.
score = Σ maxPtsᵢ · (sliderᵢ / 100), i ∈ {Energy 35, Water 10, Materials 13, Site&IEQ 42}
tier = Platinum ≥80, Gold ≥60, Silver ≥50, Certified ≥40, else none
- Energy & Atmosphere — the single largest pool (35 of 100 pts): insulation, HVAC efficiency and on-site renewables.
- Water Efficiency — 10 pts: low-flow fixtures, greywater reuse, drought-tolerant landscaping.
- Materials & Resources — 13 pts: recycled content, local sourcing, construction-waste diversion.
- Site & Indoor Quality — 42 pts combined: walkability/transit access, stormwater control, daylighting and ventilation.
Real-world relevance: this weighted, category-capped point system is exactly how LEED, BREEAM and similar schemes convert dozens of separate design decisions into one comparable tier — it rewards balanced performance over maxing a single category, since every pool is capped.
