The need for an innovative digital transformation of the construction industry is beyond doubt. However, it is fraught with a number of objective constraints, which requires the development of appropriate holistic science-based approaches and an effective practical methodology. Based on the systematization of the specifics of digitalization of the construction industry, analysis of the achieved level of innovative digital development, study of existing experience and institutional trends, the authors postulated a change management methodology as one of the key conceptual approaches to effective planning and management of digital transformation of construction. The life cycle of changes was modified on the basis of the design-process approach, and the corresponding practical assessment was carried out using the example of the implementation of information modeling technology in construction.

The article deals with the urban environment key aspects and the fixed assets reproduction on the system level, analyses the results achieved in the course of the state policy, proposes a conceptual model for the urban environment objects expanded the reproduction management.

Article systematically considers the main aspects of the cost efficiency field of innovative projects introducing solar radiation as an alternative energy source. The article offers a proprietary methodology of cost efficiency analysis for solar panels installation using the intensity of solar radiation (insolation). The calculations carried out using this method determined the amount of annual economic benefit of installing innovative solar panels.

The article is dedicated to the interrelations analyzes of the reproduction processes in apartment blocks housing stock and efficiency indicators of housing operation in the region. Scientific novelty of the research is presented by the proposed system of criteria for assessing the reproduction and operation efficiency of housing, interaction modification diagram of housing stock markets and housing services.
