【 摘 要 】

In order to contribute to a strategy of future upgrades as to mass housing inherited by Russian cities from the previous Soviet epoch, the paper addresses a problem of outer shading devices absence that leads to summertime overheating in the dwellings (inhabitants' opinion and Passive House criterion). By using the ratio of projections area (as a complex of shading elements) to windows area when estimating basic samples of the urban housing stock from the period 1950s - 70s in terms of their shading qualities, this study provides data on their potential inclination to be overheated. Thus, the model ratio is indicated. Finally, the Unshaded Windows Factor, described as the model ratio and divided by a current one, is introduced with the intention of making a preliminary assessing tool. The outcomes can be used in a process of sun-protections development during mass urban housing renovation.
