The requirements for increasing the heat transfer resistance of enclosing structures of buildings and structures are continuously increasing. At the same time, a number of buildings cannot be insulated from the outside due to their protective architectural status. Homeowners also cannot make changes to the facade design in the volume of their apartment. The design of a thermal insulation panel for mounting on the inner surface of an apartment wall is proposed. A method for calculating the heat transfer resistance of an enclosing structure insulated in this way is given.

The lack of water resources determines the problem of their rationing. Existing water consumption standards provide for a wide range of daily consumption values. This does not take into account possible measures to save water, provided for by the concept of buildings with a zero balance of water consumption. In addition, the technical specifications for the design of water supply systems include, for economic reasons, the smallest possible number of residents. The actual occupancy may exceed the planned one by several times, which requires further investment of additional funds already in the reconstruction of the newly built network. The objective of the study is to develop an analytical model of water consumption, the analysis of which allows us to evaluate the dynamics of changes in the specific water consumption with a variable population.
