Rooftop cooling structures could increase energy efficiency for utilities, industry

November 1, 2018

COLORADO, NOV 1, 2018 — University of Colorado Boulder and University of Wyoming engineers have successfully scaled up an innovative water-cooling system capable of providing continuous day-and-night radiative cooling for structures. The advance could increase the efficiency of power generation plants in summer and lead to more efficient, environmentally-friendly temperature control for homes, businesses, utilities and industries.

The new research demonstrates how the low-cost hybrid organic-inorganic radiative cooling metamaterial, which debuted in 2017, can be scaled into a roughly 140-square-foot array–small enough to fit on most rooftops–and act as a kind of natural air conditioner with almost no consumption of electricity.
