Calculation of heat transfer through the building envelope with a translucent screen

The evaluation of heat input through fences is an important part of the task of predicting the summer thermal regime of a building under a transparent dome, the interest in the construction of which in the northern regions has increased recently. In this work, a relatively simple model for engineering calculations of heat transfer through a building envelope with a translucent screen, which allows to take into account the greenhouse effect, is considered. The model has been verified by comparing the calculated and experimental data and their good agreement has been obtained, which confirms the performance of the proposed model. It is shown that the presence of a translucent screen due to the greenhouse effect significantly changes the temperature of the building wall under the dome and the value of heat flux, which implies the importance of taking into account such factors as the optical properties of the screen, the temperature of the sky, and other climatic factors when calculating the thermal regime of dome systems.
