Building Physics & Envelope

5 tools for building physics: walls, envelope heat and moisture, solar gain and roof drainage.

Ventilation & Cooling Cost EstimatorCompare three strategies for an industrial hall — ventilation only, adiabatic (evaporative) cooling and mechanical cooling — on a common fan backbone.Benchmark tested · 185/185 · Stages: Concept, Basic engineering · Benchmark reportEN UA DE NL FR ES PL
Solar Gain & PV YieldAbsorbed solar power on a surface of any shape, anywhere on Earth. Pick the site on a globe, choose a panel, box, roof, dome, hangar, tower or recessed window, and set size, tilt and azimuth.Benchmark tested · 58/58 · Stages: Concept, Basic engineering · Benchmark reportEN UA DE NL FR ES PL
Wall & Envelope Thermal CalculatorBuild a wall, roof or floor layer by layer from a 72-material library and see where it fails.Benchmark tested · 13/13 · Stages: Basic engineering, Detailed engineering · Benchmark reportEN UA DE NL FR ES PL
Roof Stormwater StudioModel roof retention, ponding and emergency overflow; normal roof drainage is an external verified flow boundary, while emergency openings are hydraulically sized and compared across code profiles.Prototype · Stages: Basic engineering, Detailed engineering · Benchmark reportEN UA DE NL FR ES PL
Building Change of Use CheckerScreen a proposed change of use and identify the engineering disciplines, evidence gaps and follow-up checks it can trigger.Benchmark tested · 314/314 · Stages: Concept, Detailed engineering, Operation & maintenance · Benchmark reportEN UA DE NL FR ES PL
