Title : Impacts of Urban Form and Socioeconomic Elements on Domestic Electricity Consumption with respect to its Impacts on Land Surface Temperature and Climate Change in Pakistan

Abstract:

Changing climatic rhythms have directly impact the built environment. The global energy scarcity and exceptional increase in energy consumption pushed energy optimization in the ambit of inevitable tasks. Energy crisis of the 1970s gave rise to the energy conservation principles but the idea of regulating domestic electricity demand through socio economic and urban form elements gained popularity in the early 2000s. Pakistan has 39% urban population while urbanization rate in Pakistan is 2.81%, devastatingly effected by the global climate change. This research investigates the effect of socio-economic features and urban form elements on domestic electricity demand and its impacts on Land Surface Temperature (LST) and pollutant emissions. Chemical effects of pollutants on the built environment, ultimately effects directing the earth towards radiating its skin being view of a remotely sensed sensor. The blistering earth surface behavior through rising (LST) by the built environment give flexibility to be used as an input for several models like thermal climate variability model in GIS. Land Surface Temperature is considered as an important indicator at all levels, local, regional, national and global. It serves as a vital element in determining urban climatology, urban heat island effects, calculation of greenhouse gases effects and their estimation, spatio-temporal rise in temperature by using various GIS models. Demographic change especially in south Asia, directly related to climate change and increasing thermal discomfort leads towards increase in energy consumption and ultimately increase in (LST), which is escalating the pollutant Like particulate matters (suspended particles, PM1, PM2.5, PM10) and enhance concentration of greenhouse gases like CH4, O3, Sox, NOx, CO and CO2. Efforts have been made viable to reduce the impacts of (LST) while using different algorithms in this research. Income level and household size is taken as socio economic characteristics. Street pattern, land cover, house size, no of storey, tree plantation, open to sky area are taken as elements of urban form. Electricity billing data is collected from the electric supply company, WAPDA and a questionnaire survey is conducted in five residential areas of Lahore as a case study. High resolution LANDSAT imagery is obtained and neighborhood plans are acquired. A total of 400 households are surveyed. The data is coded & analyzed in GIS and SPSS. Markove chain analysis for future trends in land-use and Single window algorithm, based on single thermal band ranging from 10.4-12.5 micrometer is used for (LST). Multivariate analysis techniques including correlation and regression analysis are employed. Moreover, the paper intends to highlight major trends of electricity consumption, and pollutant emissions. The key findings show that two of the socio-economic features including income and household size significantly affect electricity consumption and pollutants emissions. This research concludes that significant reduction in electricity demand is possible through socio economic and urban form changes. Incorporation of PV installation, reduce the negative impacts of (LST) on climate change, leads for attaining sustainable development goals in Pakistan.
