| 1 | # Sustainability Scoring Skill |
| 2 | |
| 3 | 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. |

| 7 | ## 1. Certification System Selector |
| 8 | |
| 9 | 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. |
| 10 | |
| 11 | ### Decision Tree |
| 12 | |
| 13 | ``` |
| 14 | START |
| 15 | | |
| 16 | |--> Where is the project located? |
| 17 | | | |
| 18 | | |--> North America (US, Canada) --> LEED-ND v4.1 |
| 19 | | | |--> Also health-focused? --> Add WELL Community Standard |
| 20 | | | |
| 21 | | |--> United Kingdom --> BREEAM Communities |
| 22 | | | |--> Also health-focused? --> Add WELL Community Standard |
| 23 | | | |
| 24 | | |--> Europe (non-UK) --> BREEAM Communities (or local adaptation) |
| 25 | | | |--> Also health-focused? --> Add WELL Community Standard |
| 26 | | | |
| 27 | | |--> Australia or New Zealand --> Green Star Communities |
| 28 | | | |--> Also health-focused? --> Add WELL Community Standard |
| 29 | | | |
| 30 | | |--> Japan --> CASBEE for Urban Development |
| 31 | | | |
| 32 | | |--> Middle East (esp. Abu Dhabi, UAE) --> Estidama Pearl Community |
| 33 | | | |--> Abu Dhabi specifically? --> Estidama Pearl is MANDATORY |
| 34 | | | |
| 35 | | |--> Other regions --> LEED-ND (most globally recognized) |
| 36 | | |--> Or BREEAM International New Construction (building scale) |
| 37 | | |
| 38 | |--> Does the client have a specific certification preference? |
| 39 | | |--> Yes --> Use client's preferred system |
| 40 | | |--> No --> Use geography-based recommendation above |
| 41 | | |
| 42 | |--> Does the project seek multiple certifications? |
| 43 | |--> Yes --> Use Cross-Certification Comparison Matrix (Section 3) to |
| 44 | | identify strategies that earn credits across multiple systems |
| 45 | |--> No --> Focus on single system for maximum point optimization |
| 46 | ``` |

| 48 | ### System Overview Comparison |
| 49 | |
| 50 | | System | Origin | Scale | Points/Score | Certification Levels | Typical Cost | Timeline | |
| 51 | |--------|--------|-------|-------------|---------------------|-------------|----------| |
| 52 | | **LEED-ND v4.1** | USA (USGBC) | Neighborhood (multiple buildings + infrastructure) | 110 points | Certified (40), Silver (50), Gold (60), Platinum (80) | $30,000-100,000+ | 12-36 months | |
| 53 | | **BREEAM Communities** | UK (BRE) | Community / masterplan | % weighted score | Pass (30%), Good (45%), Very Good (55%), Excellent (70%), Outstanding (85%) | $25,000-80,000 | 12-24 months | |
| 54 | | **WELL Community** | USA (IWBI) | Community (public realm + buildings) | Points per concept | WELL Community (pass/fail prerequisites + optimization points) | $30,000-80,000 | 12-24 months | |
| 55 | | **Green Star Communities** | Australia (GBCA) | Community / precinct | 100+ points weighted | 1 Star to 6 Stars (World Leadership) | AUD 40,000-120,000 | 12-24 months | |
| 56 | | **CASBEE Urban Dev.** | Japan (JSBC) | Urban development area | BEE score (ratio) | C, B-, B+, A, S (Superior) | Varies | 6-18 months | |
| 57 | | **Estidama Pearl** | Abu Dhabi (UPC) | Community | Credit points | 1 Pearl to 5 Pearls | Included in permitting | Ongoing | |

| 61 | ## 2. LEED-ND v4.1 Quick Scoring |
| 62 | |
| 63 | LEED for Neighborhood Development (LEED-ND) v4.1 is the most widely used neighborhood-scale sustainability rating system. It evaluates the location, design, and construction of new or redeveloped neighborhoods. |
| 64 | |
| 65 | ### Prerequisites (Mandatory -- all must be met) |
| 66 | |
| 67 | | Category | Prerequisite | Key Requirement | |
| 68 | |----------|-------------|-----------------| |
| 69 | | SLL | Smart Location | Site must not be on prime farmland, floodplain (100-yr), habitat for listed species, public parkland, or within setback of water body. Must be on previously developed land OR adjacent to existing development on at least 75% of boundary | |
| 70 | | SLL | Imperiled Species and Ecological Communities | Assessment of site for listed species; if present, habitat conservation plan required | |
