The work is dedicated to the presentation of models needed for the calculation of economically optimal criteria for heat transfer coefficients for fencing elements in terms of the heating season. The models take into account climate, financial and economic conditions in the calculation of these quantities for opaque and transparent insulation of the building, taking into account the price of combined thermal energy heat source. The proposed model allows determining the optimal thickness of insulation and heat transfer coefficients for the already built and designed houses. For optimal thermal protection parameters of the building, are calculated dynamic economic performance indicators of investment: payback period, internal rate of return, discounted profitability of the project, reduced net income. The basis of the calculation method is considered the principle of minimizing reduced costs in assessing the effectiveness of investment projects. The problem is solved with the help of authors’ specially designed software, using the actual bank rate to discount and forecast growth rate of prices of conventional thermal energy. The proposed method is illustrated by an example calculation for the city of Chisinau optimal heat transfer coefficients for the walls of the building with heat supply from boiler on the natural gas and wind power equipment. The optimal thickness of the load-bearing walls and insulation of different materials, optimum design of windows, as well as the specific loss of heat during the heating season, are determined . |
