Solutions for the Structural and Energy Rehabilitation of a Historic Monument Building in Oradea

Abstract The challenge for designers, architects and engineers lately is to offer sustainable solutions by rehabilitating and consolidating buildings with historical value. On the one hand, having the status of historical buildings, we must value them and pass them on to future generations in the spirit in which they were built, on the other hand, we must consolidate them and, why not?, if possible, make them energy efficient. The latter will only be attained if the aspect and spirit of the historic building are not altered. As material and method, this paper brings to attention an atypical and unusual case study, which offers new solutions for the energy efficiency of a historic monument building dating from around 1900, even though, in the current context of sustainable development, through the norms and legislation in force, these buildings are exempt from the obligation of energy performance indicators. The shortcomings of the building and the structural and energy rehabilitation solutions are presented. Their description highlights the shortcomings of the legislation in force and the need to adapt it to the real situation. In this paper, solutions given by the technical experts of the studied building structure were taken over and analyzed: engineers Stănescu Adrian Mircea and Radu Florin Comănescu – 2021-, and by engineer. Prada Marcela Florina - 2022 and by the energy auditor engineer Cristea Monica. Results from studies with similar topics were analyzed and taken over. The study brings to attention a comparison of the energy consumption and low carbon emissions results obtained on buildings that are not historic monuments with similar results of the case study building, a historic monument. Thus, this study demonstrates that there are energy efficiency solutions for historic monument buildings, with a positive impact on the environment by reducing CO2 emissions.
