Environmental aspects of renovations – case studies

Abstract

In this paper we would like to show the readers two case studies of energy-, environmentally- and cost-efficient renovations of contemporary buildings in Czech Republic that were assessed according to the IEA ECBS Annex 56 methodology - elementary school Kamínky 5 (built 1987) and block-of-flats Koniklecová 4 (built 1983). Both buildings are located in Brno – Nový Lískovec. They were recently renovated into low-energy standard, with emphasis on low renovation costs and high operating cost savings. In both cases the renovation reduced energy consumption by approximately 60 %. It also improved wellbeing of the users and visual perception of the buildings.In this paper we would like to show the readers two case studies of energy-, environmentally- and cost-efficient renovations of contemporary buildings in Czech Republic that were assessed according to the IEA ECBS Annex 56 methodology - elementary school Kamínky 5 (built 1987) and block-of-flats Koniklecová 4 (built 1983).
