The following article is intended to discuss the issues concerning the introduction
of passive measures aimed at improving solar protection in multi-family buildings.
A system of classifying these methods into two groups of solutions (architectural
and material-building) was applied. The first group includes issues concerning
facade design, the spatial features of which (such as loggias, balconies and other
overhangs) can be treated as one of the solar protection methods. The authors’
own studies are presented and expressed in a sequence of formulas. The formulas
enable assessment of the effectiveness of the above elements, depending on
external conditions. As far as the second group is concerned, material-construction
solutions for building facades and roofs are discussed. The solutions mentioned
include solar-control glazing, spatial shading elements (such as venetian blinds,
roller blinds), roof and façade vegetation, and the thermal mass of the building.
The essence of the functioning of the analysed solutions in relation to the
characteristic functional specificity of multi-family buildings is discussed.
Problematic areas of application of the above methods are indicated. As shown in
the study, problematic areas may include a group of utilitarian-operating, economic
and aesthetic issues, in the case of which the use of passive solutions encounters
limitations. In conclusion, the possibilities for alleviating these limitations are
highlighted. The authors’ own solutions presented in the following paper can
contribute to energy savings and may thus prove beneficial for environmental
reasons, thereby serving the aims of sustainable development.
