The Impact of Construction Modifications to a 1930s Apartment on the Life Cycle

This study examines the life cycle and energy performance of a 1930s apartment building in Brno, Czech Republic, utilizing detailed historical and technical documentation. The analysis focuses on the effects of building modifications and heating system updates on energy consumption and structural wear over time. The findings indicate that high-quality construction materials and thoughtful modernization, including insulation and heating system upgrades, significantly enhance energy efficiency and extend the building’s service life. Gas consumption for heating decreased by 62% over three decades, underscoring the importance of strategic retrofitting in older buildings. The study further highlights the role of predictive maintenance and Building Information Modeling (BIM) in optimizing long-term asset management. These insights contribute to sustainable building practices and the reduction of environmental impacts.
