One of the features of sick buildings is that people have no control over the heating or window opening.

When these controls are available, occupants frequently run the heating with windows ajar. This is bad for fuel economy and probably kicks a carbon footprint-sized hole in the local climate.

Today’s invention is a two-part lock which should help.

One element covers the window lock, the other the radiator thermostat.

These devices talk to each other wirelessly so that the window lock will only be exposed if the radiator is off.

Similarly, the radiator can’t be turned on if the window is open.
