Infrastructure Design Stage Considerations for Environmental Sustainability in Zambia

While previous studies have highlighted the importance of incorporating environmental sustainability in building designs, there is a paucity of studies which assess the extent to which design teams in developing countries consider environmental sustainability at the building design stage. Therefore, using Zambia as a case study, this study examined the extent to which infrastructure design teams in a developing country consider environmental sustainability at the design stage. The study employed a qualitative research approach using structured interviews because there are hardly any studies which have explored the extent to which designers incorporate environmental sustainability in infrastructure designs in developing countries. The data were analysed thematically using the ATLAS.ti software. The results show that environmental sustainability is not an important design consideration because it is secondary to functional, technical and aesthetic considerations. Environmental considerations are also made in an ad-hoc manner and when it is cost effective for the project. Regulatory requirements pertaining to environmental protection are adhered to without any cost considerations. It was therefore theorised that building design teams in developing countries make technical, functional and aesthetic consideration during the infrastructure design stage ahead of environmental considerations. There is a paucity of studies that have investigated whether building infrastructure designers consider issues of environmental sustainability at the design stage in developing countries. The findings have practical implications on how developing countries can foster environmental sustainability at the design stage and avoid generating a building infrastructure stock that will require environmental resilience adaptation in the future.
