A team of researchers has developed a fabric-based solution that can help buildings retain heat, potentially reducing energy use and lowering heating bills.
The approach uses a photothermal dye applied to simple materials, allowing exterior panels to absorb sunlight and keep interiors warmer.
The system, created by researchers at the University of Massachusetts Amherst, works like a thermal layer for buildings.
Heating buildings remains a major contributor to energy consumption and emissions. Instead of relying on costly renovations like new insulation or windows, the researchers focused on a low-cost, add-on solution that can be used even by renters.
The idea draws inspiration from clothing. “When you are cold, you put on a sweater,” says Carolina Aragón. “So we started thinking: what would you do if you are a building?”
The team initially explored a blanket-like covering but eventually designed removable panels that can be attached to exterior walls. These panels are coated with a photothermal dye that captures and converts sunlight into heat.
Modeling results suggest the approach could reduce heating energy use by up to 15% in residential buildings and as much as 23 percent in larger apartment blocks. Traditional retrofit methods often deliver far smaller gains.
