Solar Potential in the Existing Slovenian Building Stock
Abstract
Implementation of sustainable construction in the EU is one of the key issues for reducing energy dependence. In this framework the efficient use of solar potential incident on the building envelope is essential. The goal of the study is to check the influence of new Slovenian legislation requirements on the existing design practice and to propose general site planning guidelines. The study is carried out on seven representative urban layouts, which are assessed according to the shape of layout, density, building orientation and design. The calculations are carried out with the program SHADING. The study showed that the existing layouts are not as problematic as had been expected and that the form and orientation of buildings present a major challenge. Nevertheless, the quality and duration of insolation are highly dependent on the specifics of each case. The study showed that if the basic rules of good practice in conjunction with the existing requirements are respected, there is no need to introduce any essential changes in the existing design principles.
