FÖRÜNN Å FÖRÜNN [over and over again] - Exploring possibilities with timber buildings designed for disassemble

Abstract

Today, the building industry is forced to face large transformations to be able to reach the sustainable development goals set by Agenda 2030. This includes reducing CO2 emissions, waste, and introduce a circular use of materials. Habits of sending large quantities of usable building material to landfills are simply not acceptable in a time of climate crisis. There are in fact several ways to retain the value of a material, by repairing, reusing and recycling, etc. The purpose of this thesis is to challenge the conventional way of building by exploring the possibilities, and presenting practical ideas, on how to design for disassembly. A theoretical comparison of different prefabrication levels, timber building systems, and joints will indicate which buildings methods are able to prolong the lifespan of a building and its materials. The case study housing-project of the thesis is part of a larger collaboration, together with RISE, Kiruna bostäder AB and LTU, made for the initiative Kiruna Sustainability Centre. The project is situated in the new city centre of Kiruna – a city in the middle of a great urban transformation.
