摘要:The predominance of green spaces on the coatings of buildings and structures contributes to the formation and development of a new urban space, improves the environment, reducing greenhouse gas emissions into the atmosphere. The aim of the research is to study the various types of greening systems form a variable base of organizational and technological modelling, which allow to adopt the rational organizational and technological decisions in the construction. The research methodology and research methods are based on the theory and practice of constructing organizational and technological models and methods of rational planning in construction, decision theory, expert assessments, and comparison methods. As the results of streamlining the technological processes and operations of the roofing device with modular greening systems, the organizational and technological sequence of the roofing device with the modular greening system is formed. Application of the approaches of organizational-technological modeling in the construction of buildings with green roofs will allow verification with a limited set of experimental data.
