The Impact of Loggia Renovation on the Daylighting in a Residential Building

Overall, shading loggias play a significant role in enhancing comfort, reducing energy consumption, and improving the usability and longevity of outdoor living spaces in residential buildings. Shading loggias help in diffusing sunlight, reducing glare, and providing a more visually comfortable environment for occupants, especially in work or living spaces near windows. Natural light remains irreplaceable by artificial means. Harnessing the potential of daylight is essential, offering the advantage of free natural illumination within interiors. For the evaluation of the daylighting conditions prevailing in residential building the DF was considered as the parameter for indicating the quantity of admitted daylight. The DF values and illuminance – CIE overcast sky were calculated using DIALux evo 12.1 software. The aim of the paper is to compare three variants of the level of daylight in the rooms of the residential buildings. The results are the influence of different sun shading of loggia on changes in the conditions of natural daylight in the interior of two rooms.
