geographic-foundations

name: geographic-foundations description: > Auto-activated geographic context router for the Architect Skills plugin. Detects the country or jurisdiction of any architectural query and routes to the correct country-specific dossier (India, UAE, Saudi Arabia, USA, UK, Germany, Singapore, Japan, China, Australia). Encodes the global regulatory landscape: which authority issues which code, the hierarchy between national/state/municipal regulation, code adoption status by version year, the dominant energy/seismic/fire/accessibility codes per jurisdiction, and the cross-walk between national codes and the international reference systems (IBC, NFPA, Eurocodes, ISO, ASCE). Maintains a precise inventory of which country uses which Eurocode National Annex, which states/emirates/ Lander/prefectures publish their own modifications, and where international standards apply by reference. Triggers country-specific skills when geographic context is detected in user query (city name, project location, language cues, code reference) and supplies global framework comparisons when no specific jurisdiction is declared. user-invocable: false

Geographic Foundations

Auto-activated layer that detects geographic context and routes architectural queries to the correct country-specific regulatory dossier. Loads before any code, life-safety, structural, or planning analysis.

1. Geographic Context Detection

When a user query includes any of the following signals, route to the named country skill before applying generic content from building-codes, fire-life-safety, or accessibility-design.

1.1 Direct Detection Triggers

1.2 Indirect/Inferential Triggers

• Site climate description ("hot-arid", "tropical monsoon", "Mediterranean", "temperate maritime", "subarctic", "humid subtropical") combined with a city name -> resolve city -> country.
• Cultural cue ("vastu compliance", "qibla orientation", "feng shui", "minka", "haveli", "courtyard house with majlis") -> infer country/region (India, MENA, China/HK, Japan, India respectively).
• Standard organisation reference ("BIS spec", "DIN-tested", "JIS-marked", "GB-stamped", "BSI-certified") -> country.
• Regulatory authority name ("Civil Defence approval", "Trakhees", "Tatweer", "MoHUA", "MLIT", "Bauamt") -> country.
• Language cue in proper noun ("brise-soleil"+"ECBC" Indian usage; "rohbau" German; "shikkui" Japanese; "majlis" Arab; "joglo" Indonesian; "shophouse" Singaporean).

1.3 Default Behaviour

If no geographic context is established after the first user message, ask one clarifying question: "Which jurisdiction does this project sit under? It affects code compliance, structural design loads, energy targets, and accessibility standards."

If the user is ambiguous or operating cross-border (international firm, design competition, master-plan study), apply the international reference cluster (IBC + Eurocodes + ASCE 7 + ASHRAE + ISO 21542 accessibility + ISO 23932 fire) and explicitly state the assumption.

2. Global Regulatory Hierarchy

Each country sits in one of five regulatory archetypes. The archetype determines how clause-level questions are answered.

2.1 Archetype A -- Unitary National Code

A single nationally adopted code applies uniformly with no state/municipal variation. Cities adopt by reference.

• Singapore (Building Control Act + Building Control Regulations, administered by BCA centrally)
• Saudi Arabia (Saudi Building Code series SBC 201-1001 issued by SBCNC, mandatory in all regions since 2018)
• France (Code de la construction et de l'habitation; departments adopt by reference -- not in our Tier-1 but for context)

2.2 Archetype B -- National Model + State/Provincial Adoption

A national model code is issued but each state/province adopts a version (or modifies). Practitioner must check the state edition.

• USA (ICC publishes IBC/IRC/IECC/IFC; each state/county adopts a specific year. California adds Title 24; NYC, Chicago, Florida publish significant amendments.)
• Australia (NCC 2022 published by ABCB; each state administers via Building Act, with state-specific variations published as appendices.)
• India (NBC 2016 issued by BIS; states/UTs notify their own Building Bye-Laws and Development Control Regulations -- DCR/DCPR. Code is not legally binding by itself.)
• Canada (NBC of Canada 2020; provinces adopt -- Ontario OBC, BC BCBC, Quebec separate regime. Out of Tier-1.)

2.3 Archetype C -- Federal Framework + State/Land Sovereignty

The country has a federal framework but actual building law is state-sovereign. Each state has its own primary statute.

• Germany (Musterbauordnung MBO is a model only. Each of 16 Lander has its own Landesbauordnung -- e.g., BayBO Bavaria, BauO NRW, BauO Bln Berlin -- which is legally binding. Energy is federal: GEG.)
• UAE (Federal Civil Defence Code applies to fire; each emirate has its own building code: Dubai Building Code 2021, ADIBC Abu Dhabi, etc.)
• UK (Building Regulations 2010 apply to England; Wales, Scotland, Northern Ireland have separate regimes -- Welsh AD, Scottish Technical Handbooks, NI Technical Booklets.)

2.4 Archetype D -- Centralised National + Mandatory Strong-Form Clauses

A single national code with "mandatory provisions" that override anything else, plus permissible local supplements.

• China (GB series codes issued by MOHURD; "Mandatory Provisions" (qiangzhixing tiaowen) in red text are legally binding nationally. Cities publish DB local supplements -- DB11 Beijing, DGJ08 Shanghai, DBJ45 Guangxi -- which may only be more stringent.)
• Japan (Building Standards Act + Cabinet Order + MLIT Notifications; designated cities have planning autonomy under City Planning Act but structural and safety provisions are national.)

2.5 Archetype E -- Performance-Based Outcome Regulation

Code prescribes outcomes; deemed-to-satisfy paths are advisory. Engineered solutions admitted via approved verification methods.

• Australia (NCC 2022 fully performance-based; DTS and Performance Solution both legal.)
• UK (Approved Documents 2010+ are guidance; performance route via fire engineering reports under BS 7974, structural performance under EN 1990, etc.)
• New Zealand (NZBC, out of Tier-1.)

Many Tier-1 countries are hybrid: e.g., Japan permits performance verification (Article 38 prior to 1998; replaced by Article 37 type approval and BCJ structural performance evaluation post-1998).

3. Comparison Matrix -- Tier-1 Countries

3.1 Primary Code, Energy Code, Fire Code, Accessibility Code

3.2 Seismic, Wind, Snow Loading Codes

3.3 Code Reference Hierarchy When Designing Cross-Border

When designing for a country not in Tier-1, use this fallback chain:

1. Local code (if exists and translated/available)
2. Regional code adopted by reference (e.g., Gulf states often defer to IBC or SBC)
3. International Building Code (IBC 2024) -- North American default
4. Eurocodes (EN 1990-1999) -- European default, used in 30+ countries by adoption
5. ISO standards (ISO 21542 accessibility, ISO 23932 fire engineering, ISO 22156 bamboo, ISO 5807 plumbing) -- universal fallback
6. ASHRAE 90.1 + ASHRAE 62.1 + ASHRAE 55 -- universal thermal/IAQ/comfort fallback

4. Climate Zone Cross-Walk

Every country uses a slightly different climate zone classification. The architect must translate.

4.1 ASHRAE 169 / IECC Climate Zones (1-8)

4.2 Country-Specific Equivalent Zones

When a user gives a city, resolve to BOTH the local zone and the ASHRAE zone -- design references in this plugin use both.

5. Standards Cross-Reference Index

When a query references a standard, this table identifies the issuing country and equivalent in other regimes.

5.1 Structural & Concrete

5.2 Fire

5.3 Accessibility

5.4 Energy & Sustainability

6. Authority and Approval Bodies

When advising on permit, certification, or approval, route to the named authority.

7. Skill Routing Table

When detection succeeds, load the relevant country skill immediately and then layer specialised topical skills on top.

If the project spans multiple jurisdictions (international firm, master plan with foreign anchor tenant, embassy/diplomatic), apply the stricter of the two for each parameter and document the source per item.

8. Decision Tree

USER QUERY ARRIVES
    |
    +--- Geographic signal detected? --- YES ---> Load country-<x> skill
    |                                                  |
    |                                                  +--> Continue with topical skill
    |                                                       (building-codes, fire-life-safety, etc.)
    |                                                       FILTERED through country lens
    |
    +--- NO signal detected ----> Ask "which jurisdiction?"
                                  OR apply IBC + Eurocodes + ISO defaults explicitly

Once a country skill is loaded:

COUNTRY SKILL ACTIVE
    |
    +--- Sub-national variant? (state, emirate, Land, prefecture, city)
    |       e.g., "Mumbai" --> MCGM DCPR 2034 supplement
    |       e.g., "Dubai" --> DBC 2021 vs Abu Dhabi ADIBC 2013
    |       e.g., "NYC" --> IBC 2024 + NYC BC 2022 amendments
    |       e.g., "Bavaria" --> BayBO + DIN-based Brandschutznachweis
    |       e.g., "California" --> IBC + Title 24 Part 6 (energy) + Part 11 (CalGreen)
    |
    +--- Version year of code in force?
    |       Older codes still in force for permits issued before transition.
    |       Practitioner must know permit-issue date vs current code year.
    |
    +--- Permit phase?
            Pre-application -- planning/zoning rules dominant
            Design Development -- structural + envelope + life-safety
            Construction -- materials testing + inspection
            Occupancy -- final certification + commissioning

9. Application Workflow

1. Detect geography using triggers in Section 1.
2. Determine sub-national variation using Section 2 archetype + country-skill Section 1.
3. Identify code version in force -- transition dates vary; ask user for permit application date if material.
4. Apply country-skill clauses as primary; supplement with building-codes, fire-life-safety, accessibility-design, building-sustainability for general principles only when country skill is silent.
5. Cite clauses precisely: use "[code title] [version year] [section/clause/article number]" format -- e.g., "IBC 2024, Section 1006.2.1, Table 1006.2.1" or "GEG 2023 paragraph 19".
6. Flag stricter local override -- if state/city code is more stringent than national, the local clause governs.
7. Identify the approval authority using Section 6.
8. Cross-check with international reference if the user requests benchmark (e.g., compare ECBC 2017 wall U-values vs ASHRAE 90.1-2022 vs Passive House).

10. When Geographic Foundations Should NOT Fire

• Pure theory/precedent question with no project context ("what is critical regionalism?" -- handled by design-theory)
• Pure typological question with no jurisdiction ("what is a courtyard plan?" -- handled by spatial-planning or building-typology)
• Mathematical/computational question ("calculate U-value of this assembly" -- handled by architect-calculator)
• Question explicitly framed as international/cross-border default ("what does Passive House require?" -- handled by building-sustainability)

In all other cases involving design decisions tied to a real location, this skill should fire.
