U-CalQ – Easily Calculate U-values and Moisture
U-CalQ helps you assess the building physics of walls, roofs, ceilings, and other building components. Record component structures layer by layer, calculate the U-value, and analyze temperature and humidity profiles.
Simple or Detailed
Choose between user mode and expert mode. User mode displays the most important functions clearly. Expert mode provides additional parameters, calculations, and analyses. The mode can be changed at any time – all customers, projects, and building components are retained.
FEATURES
• Manage customers and projects • Create, edit, and duplicate building components • Compare different assemblies • Select materials and air gaps • Record individual layers and properties • Calculate U-value and thermal resistance • Display temperature profile through the building component • Show dew point and potential condensation zones • Estimate condensation amount and drying time • Display building components schematically and color-coded • Output results as a PDF report • Preview and enlarge reports before sharing • Compare selected building components and variants • Export, save, and transfer projects and building components
MATERIALS AND COMPONENTS
The material library contains typical building materials for new construction, existing buildings, and renovations, including masonry, plaster, insulation, wood-based materials, and various air gaps. Custom materials and differing values for thickness, density, or thermal conductivity can be added.
``` HUMIDITY CALCULATIONS
Depending on the desired level of detail, various methods are available:
Glaser preliminary test
Hygrothermal risk analysis – Beta
Time-dependent calculation according to the calculation principle of DIN EN 15026 – unvalidated
The extended calculations serve as a guide and for scenario analysis. They do not replace a standard-compliant building physics analysis.
REPORTS AND DATA EXCHANGE
Create PDF reports for individual or multiple building components. Reports can contain project and customer data, layer structures, calculation results, diagrams, comparisons, and notes. Reports and export files can be shared using the device's share function.
DATA PROTECTION
Customer, project, and component data are always stored locally on your device. No user account is required for basic use. You decide which reports or files are saved and shared.
IMPORTANT NOTE
The results depend on the entered material properties as well as the selected climate and usage conditions. U-CalQ is a tool for calculation and technical guidance. The app does not replace qualified professional planning or legally or contractually required documentation.
