Assessment of Changes in Incoming Solar Radiation During the Heating Period in Moscow

When calculating the energy spent on heating and ventilation of a building, the climatic characteristics of the area are taken into account. According to long-term meteorological observations, global climate warming is currently being recorded on Earth. Long-term planning of socio-economic development of territories should take into account climate change and the possibility of adaptation to them. Important parameters considered in the aspect of climate warming during the cold season are the climatic characteristics of the heating period: duration and average temperature. The possible positive consequences of climate warming for the Russian Federation include a reduction in energy consumption spent on heating buildings during the heating period. Earlier, the authors of this work considered the change in the duration and average temperature of the heating period over the period of long-term meteorological observations. It is shown that there is a tendency to decrease the degree-day of the heating period, which provides savings in calculating the energy consumed for heating and ventilation of the building. In this paper, we consider the change in incoming solar radiation on walls of various orientations over the period of long-term observations. According to the results of observations, there is no trend in the change of incoming solar radiation. Then, to calculate the heat gain from solar radiation through translucent enclosing structures, it can be recommended to use average climatic data.
