set points

Norwegian building regulations refer to the NS-EN 15251 and the NS-ISO 7730 to define indoor climate criteria in new buildings. For example, the standards prescribe a temperature band of 20-26°C for a normal office situation. Any HVAC engineer or facility manager would however willingly state that office buildings in practice are run with a much smaller temperature dead-band, and that building occupants would complain if temperatures were as high as 26°C.
