Brief Summary

To enable the Netherlands to reach the 2030 carbon emission goals, older homes need to be renovated to become more energy-efficient and comfortable. This project aims to provide shallow renovations of window films. These shallow renovations can be completed in 1-2 days and cost significantly less than a deep renovation. The study aims investigate how such window films can affect humans (low-e film and thermochromatic) if applicated in real life.
