Information provided in weather setting section are pulled from ddy file. If specific values are required for the summer, winter or evaporative design day, these can be manually entered into the weather file settings. Simply type in the desired value for each of these inputs based on the project requirements. Updating the Design Day Values is common for mission critical projects such as data centers and healthcare.
