ANALYSIS OF TECHNOLOGICAL PARAMETERS WHEN CONSTRUCTING INVERTED ROOF STRUCTURES WITH GREENERY

Subject: the subject of the study is technological parameters of the construction of roof structures with greenery. At present, the problems associated with the study of technical and technological parameters in the design of non-traditional energy-saving engineering systems, as well as their influence on the state of the housing and communal complex, have not been sufficiently studied. Research objectives: in order to reduce the labor costs in the construction of the roofing, reduce the time required to carry out repair and restoration work and ensure the quality of the roof’s operational usability, several variants of inverted roofing with greening were considered, and the best variant of energy-efficient structure and technology of erecting green roofing was identified. For modern buildings, with the use of advanced construction technologies, compliance with criteria of high constructive quality, manufacturability, and durability of building materials must be met. Materials and methods: the research uses methods of mathematical modeling, as well as modeling of technological processes in software environments. Results: based on the analysis of technological characteristics, it is established that among the technological processes and operations with different options for erecting green roofing systems, the best variant is the inverted “green” roofing with the use of modular structures. The labor intensity of erecting this roofing is 47.13 man-days, which is 38 % lower than in alternative versions, and the total duration of the roofing construction is 17 days, which is almost twice less than that in analogous designs. The use of modular technologies in greenery systems, the improvement of technological processes of erection of roofing with greenery systems are aimed at reducing the labor intensity of works and reducing the duration of construction, and in addition, implementation of innovative technologies contributes to an increase of the service life of the roofing and a longer operation of the object of construction (by 20-30 %). Conclusions: the use of rational technologies in the construction of roofing with greenery systems is the most effective solution, as the labor intensity of technological processes is reduced when constructing roofs with greenery systems in comparison with traditional types of roofs, and during the roof operation, the development of functional purpose is ensured.
