What is a Cooling Tower?
A cooling tower is a building system used to reject heat from large HVAC systems, commonly found in high-rise and commercial buildings. They transfer heat from the building to the atmosphere through water evaporation.
Why Cooling Towers Matter in Real Estate
Cooling towers matter in real estate because they affect energy efficiency, maintenance costs, and regulatory compliance. Properly designed and maintained systems reduce operating costs and environmental impact.
Example of a Cooling Tower in Action
A commercial office tower uses a rooftop cooling tower to dissipate heat from its air conditioning system, requiring ongoing water treatment and maintenance.
