Energy Efficient Reconstruction of Damaged Mass Housing Estates in Ukraine: Theoretical Aspects and German Practice

Abstract

Abstract The paper aims to investigate the significance of energy efficiency during Ukraine’s post-war recovery and strategies to improve energy efficiency in buildings in mass housing estates. The motivation for improving energy efficiency is to strengthen the country’s energy independence, reduce the burden on the national budget, meet political commitments, and reduce negative environmental impacts. Currently, energy efficiency in Ukraine lags behind that of European Union countries, necessitating a review of policies and strategies in this field. The inefficient energy use by outdated housing structures has a negative impact on overall energy efficiency. To improve energy efficiency in the housing stock, it is crucial to target Soviet-era mass housing estates, which represent a considerable proportion of the country’s housing supply and fail to meet modern standards. This article provides an overview of the energy-efficient renovation strategies applied in Germany. These endeavors involve reducing heat losses caused by convection and conduction, regulating solar gains, and improving the energy efficiency of technical systems that cater to building services and occupant comfort.
