About UValue Studio
UValue Studio is a build-up calculator for wall, roof, and floor constructions. It checks U-values, R-values, and interstitial condensation risk against primary building regulations rather than generic rules of thumb.
It's built for architects, building surveyors, energy assessors, and anyone else who needs to get compliance numbers right the first time, not just a rough estimate.
It calculates interstitial condensation risk using the Glaser method, a steady-state check (not a substitute for dynamic hygrothermal simulation software like WUFI), verified against primary legislation across 11 territories: England, Scotland, Wales, Northern Ireland, Ireland, Germany (GModG), France (RT Existant/RE2020), the US (IECC), Canada (NBC 9.36), and Australia (NCC Part 13.2, mainland and Northern Territory benchmarked separately). It uses the shared European calculation standard (BS/EN ISO 6946) throughout, and lets you reorder layers, mark any layer as stud-bridged, add a service/installation void, and view the assembly as a 3D construction detail.
Why UValue Studio
Genuine multi-territory coverage. 11 jurisdictions across five fundamentally different regulatory structures: the UK/Ireland's per-element tables, Germany/France's whole-building methods, US climate zones, Australia's insulation-addition tables, and Canada's own mix of per-element RSI tables nationally with a genuinely whole-building step code in British Columbia. Each one is primary-source-verified where possible, and clearly flagged when it's a reasonable derived approximation instead.
It doesn't skip the hard parts. Ground-bearing floor calculations (BS EN ISO 13370:2017), full Glaser condensation risk with an actual accumulation rate in g/m²/day, a monthly moisture balance (BS EN ISO 13788's fuller accumulation-and-evaporation method, covering all 11 territories) tracking whether condensed moisture can fully dry out again, and dynamic thermal response (decrement factor, time lag) for summer overheating: the points where simpler calculators usually stop.
Visual and shareable, not just a number. An interactive 3D view with material-accurate colours and correct thermal-bridging geometry, plus a PDF report built for actually submitting as project documentation.
Real products, not generic placeholders. A materials library built from actual manufacturer datasheets, so you can model the specific product you've specified.
A note on scope
Glaser-method condensation risk is a steady-state check, not a substitute for dynamic hygrothermal simulation software like WUFI. Results are a starting point for a competent person's review, not a certified assessment.
