Design drybulb changes 1.6 °C per century (linear regression R² 0.16) ~> 39.0 °C mid century. 23.0 ° Design WB = mean of 10th highest 3PM each year + (std dev * 1.94) => this Design WB was exceeded 10.2 days/year (incl std dev 4.6 days/year). 23.0 ° alternative Design WB = mean of 10th highest daily maximum each year + (1 std dev) => alternative Design WB was exceeded 10.2 days/year (incl std dev 4.6 days/year). Design wetbulb changes 0.1 °C per century (linear regression R²=0.01) ~> 23.0 °C mid century. 0.3 ° Heating DB = mean of 10th lowest 8AM each year - (std dev * 1.01) => this Heating DB was insufficient 10.0 days/year (incl std dev 4.9 days/year). -0.4 ° alternative Heating Design = mean of 10th lowest daily minimum each year - (1 std dev) => alternative Heating Design was insufficient 9.7 days/year (incl std dev 4.4 days/year). Design heating changes 0.1 °C per century (linear regression R²=0.01) ~> -0.3 °C mid century. __________________________________________________________________________ Diurnal patterns generally and coincident with design temperatures General average diurnal minimum temperature at 05:34 followed by maximum temperature at 15:54. Nighttime cooling rate 0.691 °/hr (average of all data). Diurnal pattern of days with 3PM DB ~ Design DB ~ Min at 05:49 ~ Max at 16:24 Nighttime cooling rate 0.921 °/hr from 19:50 to 07:20 (evenings following 3PM design conditions). Diurnal pattern of days with 3PM WB ~ Design WB ~ Min at -2:59 ~ Max at 15:54 Nighttime cooling rate 0.470 °/hr from 19:36 to 06:46 (evenings following 3PM design conditions).
