Temperature and Humidity Regime of Roof Space in Buildings with Glass Roofs

Abstract

The paper analyzes the temperature and humidity conditions of the roof space of buildings with translucent roofs in the winter period of operation. The work is based on the generalization of data from a number of field observations and monitoring of translucent roofs of atrium buildings in Moscow. It is established that the temperature and humidity regime of the sub-roof space of atrium buildings with translucent roofs in the winter period of operation has a significant impact on the load-bearing capacity and durability of the translucent filling of coatings (insulated glass units), as well as snow loads on translucent roofs. At the same time, an analysis of existing approaches to the design and calculation of translucent roofs atrium buildings has shown that the issue considered in this work is often not taken into account when assigning their design solutions, which further complicates their normal operation. It is established that when performing strength calculations of roof insulated glass units it is necessary to take into account the design conditions of the transitional spring-winter period, which is characterized by low outdoor temperatures and high solar activity. The thermal regime of translucent roofs of atrium buildings also has a significant impact on the formation of snow cover on similar structures, which is manifested in a different nature of the distribution of snow loads on translucent roofs, as well as on the amount of snow loads, which are several times less than the loads on similar deaf insulated roofs.
