This skill encodes the landscape of AEC academic research so outputs are field-credible. Use it to classify topics, pick precise terminology, build keyword sets, and locate where a study sits in the field.
How to use this skill
- When a topic is named, map it to one or more subfields below and adopt the canonical vocabulary.
- For literature searches, harvest the synonyms/keywords listed per subfield (AEC terminology is fragmented — the same idea has many names).
- For gap-finding, cross subfields (most novel AEC work is at intersections, e.g. BIM × LCA, computer vision × safety, generative design × embodied carbon).
- Never overstate maturity. Flag where evidence is thin, where claims are hype-driven (a real problem in AEC tech papers), and where field validation is lacking.

Cross-cutting "intersection" gap zones (where novelty concentrates)
- BIM × LCA / embodied carbon (early-design carbon feedback)
- Computer vision × safety / progress / productivity
- Digital twin × structural/energy operation (closed-loop control)
- Generative design × performance & carbon (multi-objective, carbon-aware)
- LLMs × compliance checking / contracts / specifications
- Reality capture × FM / heritage / deviation analysis
- Robotics/AM × structural & material design (print-path-aware design)
- Offsite/DfMA × supply chain digitalization
- Equity / occupant wellbeing × performance (sociotechnical, often under-studied)
Standing cautions for AEC research writing
- Define maturity honestly: "digital twin" and "AI" are over-applied; insist on the discriminating feature (e.g., bidirectional real-time coupling for a true twin).
- Generalizability is the field's weak spot: single case studies and one-building simulations dominate. Note external validity limits explicitly.
- Standards anchor credibility: cite the relevant ISO/EN/ASCE/ASHRAE standard rather than vague claims
(see the
aec-standards-codesskill). - Industry fragmentation matters: practice adoption, not just technical feasibility, is a legitimate and valued contribution in AEC venues.
