How much impact does the Wet Curtain Wall system have on building energy consumption?

The Wet Curtain Wall system is a wet curtain wall system that combines negative pressure fans and other equipment to achieve cooling and humidification functions in specific spaces (such as greenhouses, farms, etc.).
Direct cooling effect: Evaporative cooling technology can significantly reduce the temperature of the surrounding environment through the principle of absorbing heat when water evaporates. If this technology is creatively applied to building exterior walls, especially in hot and dry climate conditions, it can effectively reduce the reliance on air conditioning systems inside the building, thereby reducing the building's energy consumption in cooling.
Passive energy saving potential: Compared to active air conditioning systems, evaporative cooling technology relies more on natural processes (such as the evaporation of water) and therefore has lower energy consumption and operating costs. In building design, the rational use of this passive energy-saving strategy can significantly improve the energy efficiency of the building and reduce energy consumption and greenhouse gas emissions.
Environmental impact: Evaporative cooling technology does not require the use of refrigerants such as Freon and therefore does not cause damage to the ozone layer. In addition, because it mainly uses water resources and electricity (used to drive fans and other equipment), its environmental impact is smaller than traditional air conditioning systems.
Implementation difficulty and cost: Although evaporative cooling technology has significant energy-saving effects in theory, applying this technology in actual buildings may face some challenges, such as modification of exterior wall structures, waterproofing, water supply and management, etc. These factors may increase the difficulty and cost of implementation.
