This study looked at how coatings on windows can help save energy in buildings by controlling heat and light. The researchers wanted to understand how well these coatings work at different angles of sunlight. They used a computer model and real-world data to figure out how light passes through coated glass. They found that the simulation model gave accurate results for how well the coatings let in solar, visible, and UV light, depending on the angle of the sun. This information helps design more energy-efficient buildings with windows that balance light and heat.
