Purpose

WentylujTo combines simple building-physics calculations with a local measurement diary.

Core value

The service does not pretend to diagnose a building. It shows calculations, assumptions, a warning level and the next safe step.

Operating model

Static HTML, CSS and JavaScript run on DreamHost without a database. The PWA keeps core pages available after a connection loss.
