Design drybulb changes 2.1 °C per century (linear regression R² 0.17) ~> 35.3 °C mid century. 21.0 ° Design WB = mean of 10th highest 3PM each year + (std dev * 1.95) => this Design WB was exceeded 10.4 days/year (incl std dev 4.4 days/year). 21.0 ° alternative Design WB = mean of 10th highest daily maximum each year + (1 std dev) => alternative Design WB was exceeded 9.4 days/year (incl std dev 4.0 days/year). Design wetbulb changes -1.3 °C per century (linear regression R²=-0.24) ~> 20.2 °C mid century. -0.3 ° Heating DB = mean of 10th lowest 8AM each year - (std dev * 0.80) => this Heating DB was insufficient 10.3 days/year (incl std dev 4.3 days/year). -1.0 ° alternative Heating Design = mean of 10th lowest daily minimum each year - (1 std dev) => alternative Heating Design was insufficient 9.9 days/year (incl std dev 4.6 days/year). Design heating changes 1.3 °C per century (linear regression R²=0.17) ~> -0.2 °C mid century. __________________________________________________________________________ Diurnal patterns generally and coincident with design temperatures General average diurnal minimum temperature at 03:38 followed by maximum temperature at 15:04. Nighttime cooling rate 0.408 °/hr (average of all data). Diurnal pattern of days with 3PM DB ~ Design DB ~ Min at 05:00 ~ Max at 14:48 Nighttime cooling rate 0.728 °/hr from 19:48 to 07:23 (evenings following 3PM design conditions). Diurnal pattern of days with 3PM WB ~ Design WB ~ Min at 01:39 ~ Max at 14:54 Nighttime cooling rate 0.425 °/hr from Inf:NaN to -Inf:NaN (evenings following 3PM design conditions).
