Comfort is not a setting on a thermostat. It is the temperature of every surface around you — and Tempfort is how you find the ones costing you money.
Real surface and air temperatures, run through validated heat-flux science, show room by room where a building is wasting energy — and what fixing it is worth.
A Tempfort sensor captures indoor air and interior surface temperature in real time — no outdoor sensor or wall teardown needed.
Seven peer-reviewed convective correlations plus radiative exchange solve the surface energy balance, with a GUM-based uncertainty band on every result.
See which walls, ceilings and floors lose the most, in watts per square meter, and where insulation upgrades pay off first.
Once you're in, your dashboard keeps every reading, floor plan and report tied to your buildings — not spreadsheets.
Track temperature and humidity trends over time to spot patterns and act early.
A detailed, room-by-room breakdown that flags exactly where the losses are.
Enter your room dimensions once and Tempfort maps heat loss across every surface.
Monitor conditions in real time to keep spaces comfortable and efficient.
Every reading on this site comes from a documented physics model, not a black box.
The surface-energy-balance model behind every reading, and how each surface is graded A to D against Ontario's building code (SB-12).
If you didn't find your answer here, reach out through Contact and the Tempfort team will help — every single degree matters.
It measures indoor air and interior surface temperature and sends readings to the app, which calculates real-time heat loss without needing an outdoor sensor.
No — it's designed for building owners, not engineers. Setup takes a few minutes.
It needs Wi-Fi to sync readings to your dashboard; calculations can also run from manually entered readings.
Passwords are never stored in plain text, and your building data is tied only to your account.
