The claimed PUE of 1.035 for RedSky is unlikely. This seems to be only the internal coolant distribution efficiency but does not include the mechanical cooling nor the chillers. So far I wasn’t able to find any more detailed information about RedSky and how this PUE was calculated or measured. Considering the climate in Albuquerque, NM and the lack of large bodies of water indicates that pure free-cooling is unlikely.
