Energy Efficiency of Building Technologies and Climate Change using Geographical Information System (GIS): A Case study of use of soil, water and forest/grass in Migori County, Kenya

Abstract

Demand for building materials and products has increased considerably with the rapid growth of population thereby affecting the carbon sequestration ability of the natural environment. Traditionally, data on building materials use, energy expenditure in their sourcing and processing, and carbon dioxide equivalent generated are lacking in developing countries. The focus of this report, being part of an ongoing study is that direct impact on environment occurs at various stages in the building material usage especially at the extraction and production stages for which energy is expended. Environmental products such as soil, water and timber which are the main carbon sequesters are exploited during the manufacture / or processing of dominant building technologies in Migori thus affecting carbon sequestration potential of the natural ecosystems. The awareness levels amongst the population on energy and resource efficiency in building construction is grossly limited. The Geographical Information System (GIS) on spatial analysis of proximity and neighbourhood tools demonstrated the emerging patterns in terms of soil, water and forest/grass disturbances resulting from the activities of building construction. The ultimate goal is to facilitate formulation of energy efficiency building codes, green building guidelines, improvement of climate change strategy and Action Plan towards Nationally Determined Contribution (NDC) enhancement as well as improve knowledge in the relationship between climate change, building and ecosystem linkages between soil, water and forest cover.
