Use this data to understand conditions that affect load calculations for sizing of heating and cooling equipment.

Parameter Description
1% Cooling Dry Bulb The outdoor dry-bulb temperature used to calculate cooling loads. The 1% means that the outdoor temperature will be exceeded by 1% of the number of hours during a typical weather year.
Monthly Average Daily Min/Max The average daily minimum and average daily maximum dry-bulb temperatures for each month.
Mean Dry Bulb The average of all hourly dry-bulb temperatures for the month.
Annual 99% Dry Bulb The outdoor dry-bulb temperature used to calculate heating loads. The 99% means that, on average, the outdoor temperature will be exceeded for 99% of the hours in a year.
