Heat, water and gas supply in temples and churches are considered, taking into account the different number of people present at the Liturgy and burning candles. The formulas for determining the above-listed proceeds from paraffin candles depending on the mass of single instances. For the reconstructed Church of St. John, the Baptist at Holy Protection Cathedral in the city of Voronezh is designed of harmful emissions, and air exchange for their assimilation at different occupancy rates and given the average statistics of bought room of candles. Expressions for summary determine the total heat and moisture depending on the number of parishioners. It is recommended to use split and multi-split air conditioning systems in reconstructed and restored churches without disturbing the aesthetics of frescoes and the location of icons. The cooling capacity of such installations should be selected to ensure the required parameters of the microclimate with the occupancy of temples less than 75 % of the calculated taking into account the regulatory requirements for individual volume.

As part of the implementation of a set of works on the examination of the technical condition, calculation justification and assessment of the remaining service life of the group of buildings of the Left-Bank State Border Service of the city of Voronezh, the development of “Methodology for assessing the technical condition and calculation forecasting and justification of the remaining service life of building structures” was carried out. When developing the methodology, the requirements of the current regulatory and technical documents for the inspection of buildings and structures were taken into account. The methodology of the calculation justification is based on previously published works of the creative team under the direction of Shmelev G. D. The methodology for calculating forecasting and estimating the remaining service life of building structures is based on the following methods: expert, parametric, “load - bearing capacity” and “load - deformation”. This article provides a brief description of the methodology and its main sections. The general content of the methodology, which consists of 11 sections, is given, a detailed description of the 3 key sections of the methodology is given, which are devoted to: determining design parameters and criteria for their evaluation; methods for predicting the residual life of building structures; drawing up a report on the justification of the remaining service life of the building structures of the facility.
