Building construction and operation contributes to 39% of global carbon emissions (IEA, 2019). Active control measures to reduce these emissions tend to have a higher carbon footprint than passive design solutions. Our project examined the impact of 3M solar films in enhancing occupants’ thermal comfort and lighting conditions in RVRC tower block. We selected four pairs of rooms with clear variation in direct sunlight exposure, to conduct a comparative test. Quantitative data for parameters affecting thermal comfort (temperature, radiant temperature, relative humidity, air velocity) and light illuminance level was collected. We also conducted interviews with occupants (n=8) to understand their perceived thermal comfort. Data indicated that the treatment rooms had lower Wet Bulb Globe Temperature than control rooms, with a difference of up to 0.94°C. Based on our interview results and data analysis, we concluded that the installation of 3M solar film was effective in enhancing occupant’s thermal comfort and lighting conditions.
