Signal Radiative cooling paint costs around $6 per square metre with reported 15-20% energy savings

Summary

The report cites cost and performance figures to argue that passive radiative cooling has moved beyond the laboratory. Radiative cooling paints are priced at around $6 per square metre. 3M and SkyCool have reported energy savings of 15–20% when the materials are used in grocery and retail settings. In the outlook, indoor temperatures are said to fall by 5–10°C and energy savings can reach up to 42% in hot, dry climates. The largest gains are therefore expected where cooling demand already weighs most heavily. The outlook suggests this could turn heat management from a recurring operating cost into a materials decision made at the design stage.
