Abstract: Modular building systems in the Slovak Republic are assessed as a practical construction method and solution for a particular type of housing stock, as well as an alternative. Most existing panel buildings designed in the Slovak Republic had sufficient static reserve, allowing for the construction of rooftop extensions. Despite the considerable advantages of modular rooftop extensions, the aforementioned method of increasing available and sustainable housing stock—especially in large cities—is under-utilized in Slovakia. This paper outlines a solution for low-energy extensions—the SOLTAG concept—on the basis of knowledge acquired by studying problems related to Soltag extensions as part of the SURE-Fit (Sustainable Roof Extension Retrofit) project and practical experience from Denmark. This paper aims to assess and compare energy savings and economic benefits for three rooftop extensions of the SOLTAG concept and bricked extensions for a model area in the Slovak Republic.
