Context: Japan National Stadium
With a seating capacity of about 68,000 seats, the Japan National Stadium will hold both opening and closing ceremonies, track and field events, and olympic football. It has a total area of about 192,000 square meters. Since it is going to be one of the most used and largest venues, calculations will be based on it to provide the upper bound estimate.

Output of Dehumidifiers in the Japan National Stadium
Amount of Dehumidifiers | Total Moisture Removed | Overall Energy Consumption |
For a space of 192,000 square meters, roughly 259 dehumidifiers would be needed. | 259 dehumidifiers would remove roughly 23,432 Liters of moisture from the air significantly reducing humidity and providing an opportunity to reuse water. | Based on the usage of 1.4 kW per device, a total of 362.6 kW would be needed to power the climate control system. |
COST: 258,482 USD | 23,432 Liters saved | |
