“How can we use the nighttime chill to cool a building?”

 

Traditional HVAC systems have brought wonders to human civilization, but sometimes as engineers we would like to reinvent the wheel. To begin, everyone knows that the nighttime has its own coolness. So what if we were to take advantage of this by applying a liquid coating to the roof of a building, let the night chill cool it down, funnel it through gutters to a thermal storage, and then use it through the day? Well, this is the fundamental idea behind Night-Sky Cooling Systems. This method offers a low infrastructure low-cost, and low-energy alternative to traditional HVAC systems. That being said, Night-Sky Cooling Systems also consume large amounts of water and are heavily dependent on a cool night sky to keep them running.
