The reflective panels of academician Veljko Milković are part of a wider project of the "self-heating ecological house", which was presented 30 years ago, and is still gaining relevance today. Within this project, reflective surfaces play one of the key roles in spacial air conditioning throughout the year. One of the ideas is the adaptation of existing buildings by installing reflective surfaces on the southern facades of buildings in use.
This paper presents the results of the use of reflective panels on buildings during the last decades. Given the favorable results and low price, a wider application on residential, commercial and agricultural buildings is proposed. The model is based on high-gloss foils, sheets or coatings on a solid panel for the purpose of low-temperature heating, lighting, disinfection or cooling on the principle of directing, i.e. increasing or decreasing the usual concentration of solar radiation on the windows of buildings.
