On the Emergence of Shipping Container Homes: Adaptation to Future Climate Projections

Upcycling shipping containers for housing is increasingly recognised as a sustainable solution to housing challenges, particularly in developing economies like Nigeria. This study evaluates the thermal comfort and energy efficiency of shipping container homes under climate conditions projected for 2080. Using meteorological data for Abuja and Lagos under the Representative Concentration Pathway 8.5, a stand-alone shipping container home was simulated. The study incorporated fabric optimisation techniques, using polyurethane foam and polyisocyanurate board insulation, high-performance window glazing, and shading strategies. The findings reveal that without intervention, container homes would experience significant thermal discomfort, with annual discomfort hours exceeding 28 degrees C in both cities. However, with insulation and shading, annual discomfort hours were reduced by up to 87%, and energy consumption decreased by 76%. These results highlight the critical role of insulation and shading in enhancing thermal comfort and reducing energy demand, making container homes a viable solution for sustainable housing in hot climates. The study underscores the need for policy support to promote the integration of advanced insulation and adaptive design strategies to ensure the resilience and sustainability of container homes in future climates.
