Energy efficient wall design with stay-in-place formwork

Abstract

Abstract In this paper we analyze contemporary solutions of external wall structures made of cast-in-situ concrete with the use of stay-in-place formwork panels. The advantages of these systems are to reduce the labor input and construction period and to obtain a variety of architectural and planning concepts for buildings. Such systems are widely used in the world. This study is aimed at solving the issues of energy efficiency of external walls with the use of stay-in-place formwork. Some of the most common design solutions are considered. To determine the energy-efficient solution to the stay-in-place formwork option, we used the method of numerical simulation of heat flow processes in structures using the ELCUT 5.1 program. Based on the data obtained, the following results were achieved: an analysis was made of the applied technologies of stay-in-place formwork used to increase the energy-saving characteristics of residential buildings; the thermo-technical characteristics of the selected solutions by numerical simulation were analyzed.
