Energetic revitalization of existing buildings

Abstract

This article applies to the problem of energetic efficiency of the buildings and is especially focused on the oldest ones. Growing costs of energy, technological barriers, as well as great costs of renovation are the factors that cause the problems in implementation of efficient energetic solutions. It happens, that for above-mentioned reasons the oldest buildings lose their utility values and often become ruins. The aim of this paper is to pay the attention to the problem of traditional buildings’ revitalization, through increasing their energy efficiency. This problem was noticed in many countries and solving it became in some countries (i.ex. Germany) a rapidly growing branch of the building sector. Unfortunately in Poland this subject is still unpopular, however there are some interesting examples of monumental buildings’ revitalization, that were based on increased energetic efficiency. The article presents the types of renewable energy sources, legal acts and statistical data that relates to the subject of this work. The possibilities of traditional buildings’ revitalization using modern technologies were also presented. To extend the terminology relating to existing buildings’ modernization through increasing their energy efficiency there was a new term of energetic revitalization introduced to this work. Authors hopes that it will allow to pay more attention to often ignored problem of energy efficiency of the oldest buildings, and in long term to improving the technical condition of existing buildings and rising their utility values.
