Recently, the concepts of "passive construction" and "sustainable architecture" have firmly entered our everyday life. With these concepts, we understood that in the "passive stable architecture" the building is designed to minimize not only the energy resources spent on its operation, but also the need for mechanical control of sound, light and heat. In addition, design automation processes in energy-efficient construction have become essential. And, if the design of building structures has long been accompanied by the use of modern calculation programs, then the design of insolation - an integral part of architecture and construction lighting engineering - does not have such powerful support in the form of calculation computer programs. In this work, we present our own developed design complex, which makes it possible to calculate the illumination of internal premises with energy-efficient lighting systems based on hollow tubular light guides. The settlement complex is unique, since it has no analogues in the world. He informatively illustrates the calculations made using a full 3D view of the illuminated room and a graphic image of the distribution of light energy over a given surface. The design complex is presented on the practical example of designing combined lighting in domestic premises of the pulp and paper mill of the Vologda region.
