It depends on the climate. I used to live up north and we kept our houses and buildings around 68-71. I live in a hot climate now and it's normal to keep inside temps 75-78. In both places inside temps feel normal. The body seems to adjust it's idea of a comfortable temperature after acclimating to a new climate. When I first moved down south I kept my thermostat at 70 but it felt too cold after a few months. My most comfortable temperature is 76 now.
