In-Service Thermal and Luminous Performance Monitoring of a Refurbished Building with Solar Control Films on the Glazing System

The global increase in energy needs and environmental awareness for a more efficient use have boosted building rehabilitation to decrease consumption. installation of solar control films (SCFs) buildings with large glazing façades makes it possible reduce excessive gains through the glazing. main purpose work is assess, field experimental data, thermal luminous performances double-glazing units SCFs installed office rooms, Lisbon. An campaign was carried out simultaneously three adjacent offices: one highly reflective SCF (external installation), (internal installation) without an SCF. exterior showed best performance reductions peak indoor air temperature up 6.9 2.3 °C during representative days heating cooling periods, respectively, increasing comfort mainly period. interior had poorer since contributed radiation absorption that then emitted as heat into environment, greenhouse effect office. presence reduced illuminance levels, having positive impact on glare reduction
