SmokeGlareAir is a handy, for early building. It quickly splits cooling/heating load into sensible and latent so sizing is on point. Check cleanroom air-change rates by class and spot gaps fast. Pick the right MERV/HEPA filters with clear trade-offs for pressure drop and life. Rough-in sprinkler nodes, flows, and heads to guide early layouts. Test smoke control fans and makeup air so routes stay clear and safe. Estimate total egress time from people count, travel paths, and exit widths. Convert lux-footcandles, check UGR glare, plan daylight/skylights, and set PV row spacing to cut shading.
