For the time being such a concept in lighting engineering design is adopted only for side lit premises through windows, though the dense urban development in modern megalopolises offers nearly the same problem for buildings with overhead daylighting system. This paper presents a brief description of experimental case studies, based on the scale model method, as well as on the photometric studies of a real premise with skylights. The studies were conducted in both cases under CIE standard overcast sky with changing geometrics and photometrical parameters of model elements. The results of the studies showed the great photometric influence of opposite-standing objects on the values of daylight factor (D) in premises with top lighting system and dependence of this influence on size, position, and structural type of skylights, as well as on size and finishing of the model parts and on distance between skylights and opposite-standing building.","PeriodicalId":49907,"journal":{"name":"Light & Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135778018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Falconnier glass block technology, which was in demand at the very beginning of the 20th century, is now being revived again. Hand-blown and hollow inside, Falconnier glass blocks were widely used for glazing windows, greenhouses, lighting stairs, but of particular interest is their use as a material for glazing translucent coatings of roofs and atriums. Quite often, glass bricks could be found in blank fire walls. In most cases, glass blocks were used for the purpose of zoning spaces while maintaining daylighting, as well as in technical rooms. But Falconnier glass blocks were also used for glazing front facades. But in the mansion of the Tambov manufacturer Aseev, built in 1904–06, a unique cylindrical vault was made from this material, covering the large span of the central living room. On the territory of Russia, it was apparently the only structure of complex configuration made of Falconnier glass blocks. The structure was lost and needs to be restored. According to the results of research, its close analogue is the translucent coating of the atrium of the town hall in Zurich, which is perfectly preserved and, in fact, is very close to the historical design of the lost part of the skylight in M.V. Aseev’s mansion. At the moment, there is every reason to believe that the lost Falconnier technology was practically restored by enthusiasts, which will expand the possibilities in the field of restoration of monuments at the turn of the 19th‑20th centuries. Both of these factors – the existence of a similar constructive solution and the restored technology for manufacturing glass blocks – open up opportunities for recreating a glass barrel vault that completes the atrium of M.V. Aseev’s mansion, which is currently a museum complex.","PeriodicalId":49907,"journal":{"name":"Light & Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135778025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four stages of development and creation of artificial light sources in buildings and structures are proposed. A detailed description of the pre-electric period (regular use of fire by the man; the Bronze Age, the middle Ages and modernity) is presented. The second period begins with the opening of the voltaic arc, which can be called the beginning of the electric period. Illustrations of each discovery with lighting of rooms and buildings of the corresponding period are presented. The period of inventions, which led to the beginning of the third, gas lighting period, is described. This period includes, among other things, the combined use of gas lighting devices with electric lighting and combined gas-electric lighting. The fourth period begins at the beginning of the third millennium and continues to the present. During this period new alternative lighting sources appear along with incandescent lamps and gas-electric sources. Lighting engineering is becoming an independent branch of science and is being studied in all universities of our country, which increases the rate of appearance of new inventions and types of calculation. There are such lighting sources as fluorescent and LED lamps and fixtures. At the end of the article, the opinions of scientists on the prospects for the development of artificial lighting according to various criteria are presented. The article is provided with a large number of illustrations for all stages of development.","PeriodicalId":49907,"journal":{"name":"Light & Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135778026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of calculations of energy savings that can be provided by a passive system of using solar energy for these purposes, which, unlike active systems such as photovoltaic batteries or solar collectors for heating and hot solar water supply, does not require engineering equipment maintenance and is an element of the building itself, is part of its space-planning and a constructive solution. From the point of view of capital expenditures on its device, it is attractive. This is a “solar fireplace” or a Trombe wall – the simplest of all passive systems, the effectiveness of which was used in ancient Rome. The article presents the results of the work carried out by the Department of Architectural and Construction Design and Environmental Physics (ASPiFS) within the framework of master’s and postgraduate works on the rapid justification of the feasibility of using Trombe walls already at the decision-making stage. It is noted that the use of such structures is advisable in the new southern regions of Russia. The dependence of energy savings by such systems depending on the climatic conditions of the construction site is shown.","PeriodicalId":49907,"journal":{"name":"Light & Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135778019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The developed universal arched covering made of modular trihedral trusses can be used for multi-purpose production, storage and auxiliary buildings of various industries, as well as buildings of sporting and socio-cultural purposes. The arrangement of light apertures along the full length of the external contour of the steel lattice arches makes it possible to form a uniform background of daylighting. Directly on the inclined lattice edges of the arches, sunscreens can be placed. Changing the spacing and width of the steel lattice arches makes it possible to regulate the area of light openings and influence changes in the parameters of daylighting and insolation of the building. The aim of the research is to evaluate the design features and layout of the universal arch cover for a translucent cover with a fragmented combined system of daylight and insolation for public and industrial buildings of different technological specialization. The research methodology is based on the use of graph-analytical methods on the placement of geometric bodies in space from the condition of striving to minimize their dimensions. Analytical dependences influencing the formation of the geometric layout of lattice arch structures are presented. The results of assembling the arched coverage of a sports hall from the segments of modular trihedral trusses for different spans are given. Conclusions are formulated according to the results of the research and recommendations are given for further investigations of the presented structures.","PeriodicalId":49907,"journal":{"name":"Light & Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135778022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Light has become a real form-making and space-modelling tool. Formation of specific museum experience of lighting remains an interdisciplinary problem unifying technical aspects measured by quantitative indicators and qualitative criteria including aesthetical, psychological, and physiological aspects, forming the atmosphere of each exhibit. Museum exhibition lighting is designed using the conceptual design method, which includes conventional design tools and innovative digital technology. The conceptual design method expresses itself in interdisciplinary, synthetic and synaesthesia forms. Educational and art projects of the Stroganov Academy have accumulated a significant experience in solving different problems of museum environment light design on associative conceptual basis. A lighting system becomes: – An object of traditional art design; – A light design exhibit; – An interactive light-and-colour environment of a museum; – A synthetic environment of a park museum; – A basis of new art styles like light art and science art, media installations and 3D mapping; – Creator of a new image of a digital museum, etc. As a result, light becomes a link connecting the entire humanitarian system of a museum: its scientific, historical, educational, aesthetical and engineering components. Interdisciplinary forms of light functioning (from conventional light design to digital media and interactive projects) are limitless and will grow providing the museum environment with more new forms of information presentation and perception constantly balancing between easel and applied versions.","PeriodicalId":49907,"journal":{"name":"Light & Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135201191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
