Impact of Buildings on Climate Change: a study of carbon footprint in Oginga Odinga Street, Kisumu City

mpact of buildings in climate change; a study of carbon footprint in Oginga Odinga Street Kisumu city.

The main aim of this thesis is to investigate the impact of buildings on climate change in the lake region climate. The study investigates the embodied energy, carbon footprint and energy use in buildings in selected buildings and makes recommendations for architects to reduce buildings contribution on climate change

In the rst part, literature concerning architecture and its role in climate change is reviewed. This gives a background on how to analyse buildings in terms of there contribution to pollution. The second part involves documentation and analysis of the study area, Oginga Odinga street within Kisumu CBD. The empirical part of the study was conducted in Kisumu City CBD in September 2016. Data for the study was collected from ve case study buildings chosen according to the year of construction to show evolution of carbon footprint. The computation of building’s impact relied on the Athena Eco-Calculator software. The buildings are subsequently ranked in terms of there performance and global warming potential.

The results of the study show that newer buildings have a higher carbon footprint as compared to the earlier buildings in street. The results also reveal that there is increase of materials with higher embodied energy and decrease in utilization of passive design strategies The neglect of this strategies has led to adoption of mechanical ventilation, cooling and lighting strategies which increase the use of non-renewable energy sources and subsequently leading to greenhouse gas emissions.

In conclusion, the thesis argues that design for climate in the lake region is essential in reducing the impact of buildings in greenhouse emissions. There should be less dependence on non-renewable energy sources and biased selection of building materials with less embodied energy. This thesis hopes to contribute to architects knowledge on climatic design in the lake region and thus make a small contribution to reducing buildings carbon footprint.
