This tool tackles the “Crying Windows” problem—why tiny homes wake up with puddles on the windowsills in winter. It combines a physics engine that calculates the Dew Point of your interior air against the Surface Temperature of different window types (Single vs. Triple Pane).
It also visualizes the specific role of an HRV (Heat Recovery Ventilator), showing how it mechanically lowers humidity without freezing you out, unlike opening a window.

Why Tiny Homes need Triple Panes & HRVs.
Tiny homes spike to 60%+ just from cooking/breathing.
Why Tiny Homes “Cry”
Double pane windows are fine for normal houses, but in a tiny house with 60% humidity, they get cold enough to condense water. Triple Pane keeps the interior glass surface significantly warmer, often staying above the dew point even in freezing weather.
You cannot just “crack a window” in winter without freezing. An HRV (Heat Recovery Ventilator), like the Lunos e2, swaps stale moist air for fresh dry air through a ceramic core that captures the heat. It lowers humidity without losing your expensive heat.
