Peculiarities on Vilnius multistoried housing refurbishment from the energy efficiency aspect

Abstract

The European building stock is a major contributor to energy waste and C02 emission. Multi-storey buildings form a significant proportion of this building stock - 13 % in the old EU member states and more than one third in the new Central and Eastern European member states. Here, the prefabricated housing stock is predominant, characterized by an enormous maintenance backlog and very low structural and thermal quality. So far, no comprehensive strategies have been developed in the countries to start energy efficient multi-storey housing refurbishment. Especially effective legal and administrative structures need to be developed, energy efficient refurbishment measures chosen, complex housing renovation implemented. The main purpose of this paper is to select energy efficient refurbishment measures to encourage significant energy savings as well as housing value enhancement. Vilnius multistorey housing condition is observed, packets of energy efficient investment measures proposed, refurbishment influence to housing value increase discussed. Authors of this paper have participated in Vilnius municipality research project and formed recommendations to Vilnius housing refurbishment from the aspect of real estate value. Basing on these and other researches results Vilnius municipality programme "Renew the house - renew the city started. Pilot refurbishment project results are discussed at the end of this paper.
