High energy efficiency retrofits of residential buildings
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 7
Abstract
Building energy efficiency retrofit is considered as a valuable way to improve energy efficiency of high-energy-consumption buildings. The sustainable retrofit helps to integrate sustainable development strategy into existing buildings and retrofit projects. This paper presents findings of a study on problems and opportunities of retrofitting the old houses built in Ukraine. The research defines and virtually implements an incremental intervention strategy, which incorporates different retrofit packages for a typical house. Consequently, the upgrade packages have been simulated to assess their impact on the house’s thermal performance. The paper reports on effective ways of preserving the integrity of such a house, while improving its thermal performance to the EnerPHit standard, and discusses the benefits of introducing this holistic approach into Ukraine’s retrofit practice.
