Abstract

The construction sector accounts for a large share of global energy use and CO2 emissions, while residential floor area is growing faster than the population. This thesis responds by integrating circular economy into housing architecture with an emphasis on modularity, flexibility, and communal living. The research asks how circular principles can be translated into a modular building system that supports flexible design and functionality, and how co-housing can reduce floor area while enhancing sociocultural qualities. Methodologically, an adapted Integrated Design Process is used, combining analysis of circular economy, DGNB, design for disassembly and life cycle assessment with user and site studies, followed by iterative sketching and synthesis with technical checks (including energy and indoor environment). The outcome is a co-housing development in Hasseris, Aalborg (approximately 1200–1500 m² with 15–20 dwellings and shared facilities): a series of flexible double houses with an interior wall system that can be hand‑disassembled and repositioned within a modular grid, and an exterior wall system that enables disassembly and relocation of the whole building. Main structural components are designed for reuse, and materials are selected as low‑emission and non‑hazardous, informed by LCA. The thesis presents a concrete design approach and principles for circular, space‑efficient housing; quantitative performance results are not provided here.

Byggeri står for en stor del af verdens energiforbrug og CO2‑udledninger, samtidig med at boligernes areal vokser hurtigere end befolkningen. Dette speciale adresserer disse udfordringer ved at introducere cirkulær økonomi i boligarkitektur med fokus på modularitet, fleksibilitet og fællesskab. Problemformuleringen undersøger, hvordan cirkulære principper kan omsættes til et modulært byggesystem, der giver design- og funktionsfleksibilitet, og hvordan co-housing kan reducere boligareal og styrke sociokulturelle kvaliteter. Metodisk anvendes en tilpasset Integrated Design Process med analyse af cirkulær økonomi, DGNB, design for adskillelse og livscyklusvurdering samt bruger- og kontekstanalyse, efterfulgt af iterative skitser og syntese med tekniske verifikationer (bl.a. energi og indeklima). Projektet munder ud i et co-housing byggeri i Hasseris, Aalborg (ca. 1200–1500 m² med 15–20 boliger og fællesfaciliteter): en serie fleksible dobbelthuse med et indvendigt vægsystem, der kan hånddemonteres og flyttes i et modulært grid, samt en ydervægsløsning, der muliggør demontering og flytning af hele bygningen. Hovedkonstruktioner kan genbruges, og materialer udvælges som lavemitterende og uden sundhedsrisici med afsæt i LCA. Specialet præsenterer et konkret designgreb og principper for cirkulært, pladsbesparende boligbyggeri; kvantitative effektmålinger fremgår ikke her.
