Practical building science tools and references to help you assess risk, improve performance, and make better design decisions.
Evaluate condensation risk and interstitial moisture potential in building assemblies using the Glaser method. Ideal for early design reviews, material selections, and performance checks.
LAUNCH CALCULATOR →
Visualize the properties of air including temperature, humidity, dew point, enthalpy, and more. A fundamental reference for understanding thermal conditions and moisture behavior in buildings.
VIEW CHART →
See how buoyancy, temperature difference, and building height combine to drive airflow through a structure. Adjust conditions and openings and watch the neutral pressure level and pressure profile respond in real time.
LAUNCH SIMULATOR →Run measured hourly temperature and humidity through the VTT mold growth model. Drop in a year of logger data to see where the mold index crosses the visible-growth threshold, compare material sensitivity classes, and export the hourly results.
