The 2018/844 Energy Performance of Buildings Directive (EU) has widened the scope appropriate design buildings from a pure energy performance and carbon emissions perspective to wider that includes indoor comfort, air quality among others. To this effect, external parameters, especially solar energy, have strong impact on in Mediterranean regions, which requires careful consideration when it comes benefiting natural lighting while avoiding overheating. This paper addresses considerations deep renovation housing block climate Republic Malta, comparing some usual illuminance ranges achieve optimal conditions based international recommendations. DesignBuilder v7.0.0.102 been selected software model building calibrated through experimental measurements. enabled evaluated effectiveness suggested improvements be determined. Results pointed out under study satisfies standards about prevention visual discomfort only. Increasing size windows identified zones, first floor, was found help improve other characteristics. One proposed designs (Model 6) replaces single-glazed with double-glazed include an spectrally-selective coating would significantly access light bringing closer recommended levels Annual Sunlight Exposure reducing artificial usage by up five times. relocation room spaces could also reduce use lighting.
