RENOVATION USING PREFABRICATED FAÇADE ELEMENTS

Sammanfattning: The building sector uses about 40% of the total global energy use. Sweden aims to reach its new goal to reduce the energy use in their residential sector as well as commercial sector by 20%, which should be reached by year 2020 and 50% by year 2050. To find a solution to this problem European Union (EU) collaborated with IVL (Swedish environmental Research Institute) and LKF (lunds Kommuns Fastighets AB) on a pilot project in Linero district, Lund. This master’s degree thesis is a part of that pilot project. This study is based on a literature review with a qualitative evaluation and the aim of the thesis was to identify a highly industrialized method of a façade that could provide a better additional insulation to the existing building façade to make it energy efficient. Moreover, this thesis observed the potentials of introducing the concept of prefabricated façade element onto the Swedish market for the renovation projects of the Swedish Million Programme. The study scrutinized numerous facades available in the European market; as a result, a top selection was gathered of the 15 promising prefabricated facades in the European market.These 15 promising prefabricated facades were analysed and compared to determine the best fit for the Swedish climate. After thorough investigation three prefabricated facades from the European market were selected as most promising for the renovating the Million Programme of the Linero project. To evaluate these options, the study employed various software tools such as WUFI, AUTOCAD, and HEAT2. Comprehensive analyses encompassed moisture risk assessment, attachment and fixation to existing structures, and thermal performance. While all three facades demonstrated commendable results suitable for future Million Programme renovations, one of them emerged as the top performer.
