Determine whether the building is open or surrounded by buildings, and what is the background noise of the surrounding environment, so as to calculate the shaded area to be considered when heating load.

Observe whether there are factory boiler rooms, kitchens, etc., and clarify the items to be noted when outdoor air inlets.
