- Abstract
- A fifth of Sweden's current housings were built during the Million Programme (1965 - 1974). A substantional amount of these houses are in a great need of renovation, and furthermore, these houses do not have the same energy performance that modern houses have. As a part of decreasing the building sector's carbon emissions, reaching the climate targets and at the same time utilize already existing buildings and thus avoid the big accumulated emissions of new production, it's of great importance that these buildings are renovated, and especially that they are well renovated. The purpose of this study was therefore to examine a potentially effective renovation method for these common dwelling houses; how the energy efficiency and the thermal... (More)

The purpose of this study was therefore to examine a potentially effective renovation method for these common dwelling houses; how the energy efficiency and the thermal climate in the houses was affected. To do so, energy usage from theoretical energy models from IDA-ICE were compared with measured values, and air tightness tests, as well as thermography tests were made to evaluate the parameters. Furthermore, a survey was sent to the house residents, where the respondents gave an indication about how the renovation was experienced and how the thermal climate affected the residents. The results of the study revealed that the thermal climate was generally enhanced and that the residents experienced the renovation somehow bothersome, though most were satisfied and thought that the area as a whole had improved. The results also showed that the energy efficiency of the houses was improved with 25 – 29 %, depending on if the measured or the simulated result was used. The results also indicated that the renovation method inherently is applicable on most apartment buildings from the Million Programme, due to the building frame's formation. (Less)
- Abstract (Swedish)
- Under det svenska miljonprogrammet byggdes drygt en miljon bostäder under en 10-årsperiod, där lamellhus i 3-våningar är den dominerande hustypen. Produktionen var industriell och rationell med enhetliga metoder och utföranden. Byggnaderna har under åren haft varierad grad av underhåll, men genomgående för husen har generellt varit bristfällig skötsel. Gemensamt för en stor del av byggnaderna är således deras stora renoveringsbehov, då den tekniska livslängden dessutom uppnåtts. Som en del av de klimatpolitiska målen läggs samtidigt nu en allt större vikt på energieffektivisering av befintliga hus, då produktionen av nya hus innebär stora klimatavtryck, samtidigt som äldre hus har en, med dagens mått, bristfällig energiprestanda.

- Under det svenska miljonprogrammet byggdes drygt en miljon bostäder under en 10-årsperiod, där lamellhus i 3-våningar är den dominerande hustypen. Produktionen var industriell och rationell med enhetliga metoder och utföranden. Byggnaderna har under åren haft varierad grad av underhåll, men genomgående för husen har generellt varit bristfällig skötsel. Gemensamt för en stor del av byggnaderna är således deras stora renoveringsbehov, då den tekniska livslängden dessutom uppnåtts. Som en del av de klimatpolitiska målen läggs samtidigt nu en allt större vikt på energieffektivisering av befintliga hus, då produktionen av nya hus innebär stora klimatavtryck, samtidigt som äldre hus har en, med dagens mått, bristfällig energiprestanda. Med anledning av den standardiserade stomtypen, behovet av mer energieffektiva byggnader, samt det stora renoveringsbehovet som existerar hos en av landets vanligaste byggnadstyp, behövs lönsamma och effektiva renoveringsmetoder som fler fastighetsägare vågar satsa på. En sådan metod utförs på Brf Tingvallen i Lund.
Syftet med examensarbetet är att utvärdera och undersöka effekterna på byggnadernas energiprestanda och deras termiska inneklimat till följd av renoveringsmetoden som tillämpats på Brf Tingvallens lamellhus. Detta för att förhoppningsvis ge kunskap och inspiration till branschen, och uppmana till vidare forskning och effektivare renoveringar av miljonprogramshusen.
För att utvärdera renoveringsmetodens effekter upprättas energimodeller i IDA-ICE, vars resultat jämförs med uppmätt energistatistik från NODA-systemet. Därtill utförs lufttäthetsprovningar och termografering av några av de renoverade lägenheterna. Dessutom används enkätundersökningar som besvaras av de boende, för att undersöka upplevelsen av renoveringen och det termiska inneklimatet.
Arbetet visar på att renoveringsmetoden upplevdes relativt besvärlig för en del boende, men enligt många ansågs den vara nödvändig och inte speciellt jobbig, sett till lyftet det gav för lägenheterna och området i helhet. Dessutom visar resultatet på att det termiska inneklimatet i lägenheterna har förbättrats något. Därtill visar analysen på att energiprestandan för fastigheterna verkar minskar med ca 25 - 29 %. Studien visar även att renoveringsmetoden kan tillämpas på de flesta byggnader med bokhyllestomme, varför metoden har stor potential att nyttjas vid renoveringar av flerbostadshus från miljonprogrammet.
