+The Backbone · Before You PlayA² Data Ecosystem ArchitectureHow the platforms record and share data — worth reading before you try them.
Before exploring the platforms, understand the data infrastructure behind them. This voice-narrated interactive presentation explains how learner data flows from input through AI-enhanced training to research-grade outputs — the architecture that makes every A² platform traceable, auditable, and research-ready.
Decision-support tools and digital twins for advanced coursework, professional development, and research applications.
+Research / Faculty · Cornell AI4S Visiting Professorship VisionNano-Modified Construction Materials Digital TwinMulti-objective optimisation digital twin for nano-modified construction materials.
NanoLCA-DT
A conceptual prototype demonstrating AI-driven multi-objective optimization of nano-modified construction materials. Integrates ML surrogate models, cradle-to-gate lifecycle assessment (ISO 14040), and NSGA-II Pareto optimization across three objectives: lifecycle cost, embodied carbon, and durability. Features grey-box digital twin architecture, voice narration, and agentic AI infrastructure (Skills, MCP, REST API).

EVNN-DC Decision Lab
An AI-powered multi-criteria decision analysis platform for data center lifecycle investment under uncertainty. Features Monte Carlo uncertainty simulation, Bayesian AI guidance with explainable recommendations, TOPSIS ranking, construction risk scenarios with decision-based learning, pre-module knowledge assessment, comprehensive 16-question learner surveys with certificate generation, and full session JSON data export for POC validation research. Built for both education and research.
Interactive simulations designed for classroom deployment — from K-12 outreach to freshman-level data center training.
+Freshman / Intro Level · 1 of 20 Certificated Data Center ModulesData Center Lifecycle Risk SimulationFreshman-level simulation — one of 20 certificated data centre modules.
NEXUS-DC · Power Up
A multi-role data center lifecycle risk simulation where students build and manage a $500M+ data center across 3 crisis waves — balancing cost, uptime, safety, sustainability, and stakeholder satisfaction. Features 6 professional role perspectives, 8 scoring dimensions aligned to ISO 31000 and PMBOK, and both guided and blind play modes with transparent scoring.
+K-12 Outreach & AGC Skills ChallengeConstruction Site SimulatorGame-based K-12 outreach simulator, also used for the AGC Skills Challenge.
BuildSim · Job Site Simulator
An HTML5 game-based construction management simulator where students drag and drop facilities on a blueprint grid, optimize worker travel distance, respect site constraints, and manage resources — all while receiving real-time AI formative feedback on every decision. Includes scoring engine, leaderboard, certificate generation, and a comprehensive formative assessment report.
+Student ValidationWhat Students SayValidation data from students who used the platforms, including BuildSim results (N=50).
