Design heating changes 1.2 °C per century (linear regression R²=0.23) ~> 1.9 °C mid century. __________________________________________________________________________ Diurnal patterns generally and coincident with design temperatures General average diurnal minimum temperature at 05:20 followed by maximum temperature at 15:59. Nighttime cooling rate 0.773 °/hr (average of all data). Diurnal pattern of days with 3PM DB ~ Design DB ~ Min at 02:37 ~ Max at 15:48 Nighttime cooling rate 0.990 °/hr from 19:52 to 06:44 (evenings following 3PM design conditions).
