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. |
