The goal of transition to information modeling (BIM) in construction is to increase its efficiency by reducing project collisions, introducing innovations into projects and improving the interaction of participants in the investment and construction cycle on the basis of uniform digital models. Analysis of the Russian and foreign experience of BIM showed similarities in a number of areas such as the creation and use of digital libraries and databases for designing complex buildings. The authors associate prospects for the effective implementation of investment and construction projects in the emerging innovation and digital environment with the integration of BIM and project management methodology and with a territorial innovation management system throughout the object's life cycle. For the first time, on the basis of the international Oslo Guidelines, a classification of energy-saving innovations for a residential house project is given, calculations are made to evaluate their effectiveness at the operational stage, and approaches are formulated to create an innovative investment management system for building projects in the digital economy environment.
