AB Lighting in heritage is complex because of the forms intervening in it. The historicalevolution of cultures has not been analytical and therefore, the shapes involved di er greatly fromthe cuboids typically found in 21st century architecture. As a vector, light inevitably attaches tosurface sources. In this research, we focused on 3D curved geometries. Following a di erent trailto radiative transfer by virtue of detailed knowledge of the spatiality of volumes, we present newexpressions, previously undefined in the literature, that are derived from a combination of surfacesthat we have found in many archaeological sites around Asia. In the discussion, we start from theparticularities of spherical surfaces where a normal vector has to pass through the center. By meansof easy calculations, we deducted innovative laws. These in turn, allowed us to formulate severalnew expressions for configuration factors based on the adroit use of spherical fragments. The methodeasily extends to organic shapes that are often contained in the sustainable architecture of the past.The method finishes with suitable algorithms to assess the reflections in such curved forms. Finally,we implemented the results in our creative software. In this way, we enhanced the sustainableparadigms for heritage structures in Asia that we present as a conclusion of the article.
