For the following components, you must enter the percentage of total floor area served:
HVAC (Heating & Cooling): Enter the percentage of the total floor area served by each heating and cooling type.
Examples:
If an entire building has a Hot and Chilled Water HVAC system, enter 100 for this component to indicate 100%.
If a warehouse has a Package Unit HVAC system in the office area, which is 12% of the building, and has Space Heaters in the warehouse area itself, enter 12 for Package Unit and 88 for Space Heaters.
If the warehouse only has the Package Unit system in the office area, just enter 12 for Package Unit.
Sprinklers: Enter the percentage of the total floor area served by each type of sprinklers.
Elevators (by Area): If you use Elevators by Area, you should enter 100 to indicate that 100% of the floor area is served by elevators. It is always better to use Elevators by Count when you know the number and type of elevators in the building.
Exterior Walls: Enter the percentage of each wall type in the building.
