In the “Thermostat” rule, if it exists, replace “which is tracked in degrees Celsius” with:

which is an integer which may be negative, tracked in degrees Celsius

Then add to that rule, if it exists:

Any Architect may Monitor any Architect’s statistics at any time, by performing the following atomic action (“Modules” referring only to Modules on the Monitored Architect’s Site in this case):-

* Setting the Monitored Architect’s Temperature to 20 (if there is a Power Module) or -20 (if there are no Power Modules)
* Reducing the Monitored Architect’s Temperature by 1 for every Corridor Module which is adjacent to an Empty square or to the edge of the grid
* Increasing the Monitored Architect’s Temperature by 1 (to a maximum of 20) for every Power Module
* Setting the Monitored Architect’s Oxygen to the percentage of Modules (rounding down) which are either Life Support or Hydroponics
* Setting the Monitored Architect’s Food to 10 times the number of Hydroponics and Dock Modules
