The focus of this dissertation is on existing housing areas: in industrialised western countries, in 2005, the number of existing buildings that are taken care of, maintained, repaired, renovated or restructured for other functions is higher than the number of buildings that are (new) built. This is a review dissertation, based on empirical material and further reflections from previous research projects dealing with Swedish housing renovation: private-owned old single-family housing areas and large housing areas from the 1950s, 60s and 70s, mainly owned by housing companies. The concepts of careful renovation, environmentally-friendly renovation and sustainable renovation are analysed as different approaches to housing renovation. The aim is to present an interpretation of sustainable renovation that includes the goals both of careful renovation and of environmentally-friendly renovation as necessary components of sustainable development. This dissertation identifies and analyses the main issues that may be faced during renovation and that have a relevant impact on the environment, the architecture or the inhabitants, and describes the renovation actions that have been used in the studied projects. It concludes with reflections about positive results, incongruities and challenges that may be found in projects of sustainable renovation. / QC 20100928

Syftet med denna undersökning var att belysa tre aktörsperspektiv på den kommande renoveringsvågen av GotlandsHems byggnadsbestånd: fastighetsägar-, kulturvård- och brukarperspektivet. Utifrån dessa perspektiv ville undersökningen identifiera målkonflikter samt nyansera och problematisera den rådande diskussionen kring kulturvärden i GotlandsHems bebyggelse från 1930–1975 samt sätta in renoveringsvågen av GotlandsHems bostadsbestånd i en större nationell och internationell kontext. Frågeställningarna inkluderade huruvida kulturvärden tar någon plats i diskussionen kring den kommande renoveringsvågen av GotlandsHems bostadsbestånd och vilka målkonflikter, mellan vilka aspekter, som gick att identifiera. Renoveringsvågen place- rades i en större kontext genom sitt ursprung i EU:s gröna giv och Sveriges nationella strategier. En fallstudie med tre kvalitativa intervjuer och en innehållsanalys genomfördes. Analysen identifierade fem teman: oro för hyreshöjningar, kommunikation, för- delar med energieffektivisering, återbruk och varsam renovering. I diskussionen identifierades fem målkonflikter mellan aspekterna hyresgäster, affärsmål, energieffektivisering och kulturvärden. Slutsatsen var att kulturvärden har diskuterats rikligt med flera olika infallsvinklar av alla aktörsperspektiv i denna undersökning. Diskussionen har däremot inte riktigt fått den plats som GotlandsHem borde ha gett den i förarbetet inför renoveringsvågen. En tidig utredning i renoveringsvågens projekteringsprocess av kulturvärden i GotlandsHems bostadsbestånd kommer göra avvägningar och konflikthantering mellan affärsmål, energieffektivisering, hyresgäster och kulturvärden enklare. / The purpose of this study was to highlight three perspectives on the upcoming renovation wave of GotlandsHem's building stock: the property owner, integrated conservation and user perspectives. The study wanted to identify goal conflicts as well as nuance and problematize the current discussion on cultural values in GotlandsHem's building stock from 1930-1975. From these perspectives it also aimed to place the renovation wave in a broader national and international context. The research questions included whether cultural values are considered in the discussions about GotlandsHem's upcoming renovations and which goal conflicts, between which aspects, that could be identified. The renovation wave was contextualized with a walkthrough of EU's Green Deal and Sweden's national strategies. A case study with three qualitative interviews and a content analysis was carried out. The analysis identified five themes: concerns about rent increases, communication, benefits of energy efficiency, reuse, and careful renovation. The discussion identified five goal conflicts between the aspect’s tenants, business goals, energy efficiency, and cultural values. The conclusion was that cultural values has been discussed abundantly with several different angles from all perspectives in this survey. However, the discussion has not really been given the place that Gotland- sHem should have given it in the preparatory work for the renovation wave. An early investigation in the renovation wave's planning process of cultural values in GotlandsHem's housing stock will make trade-offs and conflict management between business goals, energy efficiency, tenants and cultural values easier.
