Abstract
The reconstruction of balconies and loggias is a key element of the renovation of apartment buildings. Artificial light will never replace natural light. Every day, one must make full use of the potential of daylight and enjoy an advantage—free-of-charge natural light entering the interior. When renovating balconies, people often change the character of this protruding structure from a façade to a loggia. This is also the subject of this paper. For the evaluation of the daylighting conditions prevailing in residential building, the Daylight Factor (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 9.1 software. The aim of the paper is to compare two variants of the level of daylight in the rooms of the residential building. One option to bring in even more natural light than a window is a variant with balconies. Loggias are satisfactory in terms of static and thermal technology, but daylight conditions are deteriorating. The article provides an insight into the solution of the renovation of balconies and loggias in a specific apartment building. The result shows their influence on changes in the conditions of natural daylight in the interior of two selected rooms.
Highlights
People are spending more and more time indoors and losing outdoor direct contact with the sun’s rays
It can be concluded that the influence of the color of the loggia walls on the conditions of Daylight Factor (DF) in the interior is not large
This study examines the feasibility of renovating balconies into loggias to assess In addition to the DF, the lighting level was taken into account in this study
Summary
People are spending more and more time indoors and losing outdoor direct contact with the sun’s rays. The importance of daylight consists of three basic dimensions’ the field of health, the field of performance, and the feeling of well-being [1,2]. Generation” is taking the health risk of spending more time inside. People do not fully comprehend the sheer amount of time they are spending inside. This detachment from the natural world—and natural sunlight, —can have negative health impacts and can even have deleterious effects as serious as respiratory problems or seasonal affective disorder. Daylight has a large influence on environmental conditions to improve ambience, visual comfort, well-being, and the health of occupants [3,4,5,6,7]
