I recalled this tangent to the post about Japan and AC and comments about various ways that heating and cooling is done in data centers. The NREL has the diagram of their cooling efficiency, how it was designed and measured and reusing waste heat from computing to heat other parts of the campus. > Snow melt loop in the courtyard of the ESIF's main entrance > If surplus heat is available, the PHW loop can provide heat to the campus heating loop. During transition months (April and October), excess heat from the ESIF has been sufficient to provide heat for other buildings, shortening the time boilers are needed to provide campus heat.
