Context cost

Sustainability Scoring loads about 7.7k tokens when it runs, and up to ~31k if it reads all its reference files. Until then it costs about 138 tokens; SKILL.md has 3,197 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~138
When it runs · the whole SKILL.md, loaded when a task matches
~7.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Score urban designs against LEED-ND, BREEAM Communities, WELL Community Standard, Green Star Communities, CASBEE Urban Development, and Estidama Pearl Community Rating System. Generates detailed scoring reports with credit-by-credit analysis, achievability assessment, and optimization recommendations. Use when the user asks to score a design for sustainability, assess LEED-ND credits, evaluate BREEAM compliance, check WELL community criteria, calculate a sustainability rating, or optimize a design for green certification.

Sustainability Scoring Skill

This skill provides comprehensive sustainability certification scoring for urban designs and masterplans. It covers the six major neighborhood/community-scale rating systems used globally: LEED-ND (US), BREEAM Communities (UK/Europe), WELL Community Standard (global, health-focused), Green Star Communities (Australia/NZ), CASBEE Urban Development (Japan), and Estidama Pearl Community Rating System (Middle East). The skill generates credit-by-credit scoring analyses, identifies optimization opportunities, and produces professional scorecard reports.


1. Certification System Selector

Use the following decision tree to select the appropriate certification system(s) for a given project. Geography is the primary driver, but project focus and client preference may override.

Decision Tree
START
  |
  |--> Where is the project located?
  |      |
  |      |--> North America (US, Canada) --> LEED-ND v4.1
  |      |      |--> Also health-focused? --> Add WELL Community Standard
  |      |
  |      |--> United Kingdom --> BREEAM Communities
  |      |      |--> Also health-focused? --> Add WELL Community Standard
  |      |
  |      |--> Europe (non-UK) --> BREEAM Communities (or local adaptation)
  |      |      |--> Also health-focused? --> Add WELL Community Standard
  |      |
  |      |--> Australia or New Zealand --> Green Star Communities
  |      |      |--> Also health-focused? --> Add WELL Community Standard
  |      |
  |      |--> Japan --> CASBEE for Urban Development
  |      |
  |      |--> Middle East (esp. Abu Dhabi, UAE) --> Estidama Pearl Community
  |      |      |--> Abu Dhabi specifically? --> Estidama Pearl is MANDATORY
  |      |
  |      |--> Other regions --> LEED-ND (most globally recognized)
  |             |--> Or BREEAM International New Construction (building scale)
  |
  |--> Does the client have a specific certification preference?
  |      |--> Yes --> Use client's preferred system
  |      |--> No --> Use geography-based recommendation above
  |
  |--> Does the project seek multiple certifications?
         |--> Yes --> Use Cross-Certification Comparison Matrix (Section 3) to
         |           identify strategies that earn credits across multiple systems
         |--> No --> Focus on single system for maximum point optimization

Key Insight

A project pursuing both LEED-ND Gold (60 pts) and WELL Community Standard can achieve significant overlap by focusing on: walkability, mixed-use, transit, green space, stormwater, water efficiency, and community engagement. These strategies contribute to both certifications simultaneously, reducing the incremental effort and cost of dual certification.


4. Scoring Workflow

Follow this six-step process to score any urban design project against a sustainability certification system.

Step 1: Project Characterization

Gather the following information about the project:

  • Location (city, state/province, country, climate zone)
  • Site area (hectares)
  • Gross floor area (sqm) by use (residential, commercial, institutional)
  • Number of dwelling units and unit types
  • Density (DU/ha and FAR)
  • Transit access (type, frequency, distance to station/stop)
  • Surrounding context (urban/suburban/rural, adjacent land uses)
  • Client certification goals (system, target level, timeline)
Step 2: Prerequisites Check

For the selected certification system, evaluate every prerequisite requirement against the project design. Prerequisites are mandatory -- failure to meet any single prerequisite disqualifies the project from certification.

  • Create a checklist of all prerequisites
  • For each prerequisite: assess compliance (met / not met / needs modification)
  • If any prerequisite is not met: identify what design changes are needed to achieve compliance
  • Prerequisites are non-negotiable -- resolve all prerequisite issues before proceeding to credit scoring
Step 3: Credit-by-Credit Scoring

For each credit in the selected system:

  • Determine if the credit is applicable to the project (some credits are site-specific or use-specific)
  • Assess the project's current compliance level (points achievable under current design)
  • Identify the gap between current design and maximum points
  • Classify the credit achievability: Easy (high certainty, low cost), Moderate (achievable with design modifications), Difficult (requires significant investment or is context-dependent), N/A (not applicable to this project)
  • Calculate a preliminary score
Step 4: Gap Analysis

Compare the preliminary score to the target certification level:

  • Calculate the point gap (target score minus preliminary score)
  • Identify the most cost-effective credits to close the gap (see Section 5: Optimization Strategy)
  • Prioritize credits by: achievability, cost, synergy with other credits, alignment with design vision
Step 5: Optimization Recommendations

For each credit in the gap:

  • Specify the design modification needed to achieve the credit
  • Estimate the relative cost impact (low / moderate / high)
  • Identify synergies (does this modification help achieve other credits?)
  • Identify trade-offs (does this modification conflict with any design goals?)
Step 6: Final Scorecard Production

Produce the scorecard in the format specified in Section 6, with:

  • Credit-by-credit breakdown with point values
  • Achievability assessment (Easy / Moderate / Difficult / N/A)
  • Current compliance status (Achieved / Partial / Not Achieved / N/A)
  • Optimization recommendations
  • Total score and projected certification level

5. Optimization Strategy

Tier 1: Low-Hanging Fruit (High Points, Low Cost)

These credits should be pursued first as they require minimal additional investment beyond good design practice.

LEED-ND Low-Hanging Fruit:
