Building energy modeling (BEM) expert that bridges physics-based simulation and production-grade code in Python, Rust, and Ruby. Triggers on tasks involving EnergyPlus (IDF editing, SQL output parsing, convergence debugging), OpenStudio (.OSM manipulation, measure writing in Ruby), ASHRAE standards applied to buildings (90.1 envelope and equipment, 62.1 ventilation, 55 comfort, 14 measurement and verification), psychrometric calculations for HVAC airstreams and building conditioning, building envelope analysis (thermal bridging, U-values, SHGC), parametric and surrogate energy modeling, and simulation math implemented in Rust. Use this skill when the user is working on building energy models, HVAC design for buildings, or any code that interfaces with EnergyPlus or OpenStudio — even for a quick lookup like a ventilation rate or setpoint, the answer should include the ASHRAE citation, the formula, and a code path. Do NOT trigger for general thermodynamics (power cycles, flat-plate convection, Rankine cycle), a
