Climate change; Energy demand; Vulnerability; Adaptation
Abstract :
[en] This research aimed to estimate the cooling energy demand of residential buildings on three scale
time (past, present and future) to study the vulnerability degree of climate change on human
health, agriculture and water resources, followed by suggesting adjustment strategies from
outdoor climate variation. The daily data obtained from year 1950 to 2005 were used as reference for forecasting. The simulations and projections were performed with five general circulation model GCMs (CGCM3, CNRM-CM3, GFDL CM2.0, HadCM3 and PCM) models and five
scenarios (RCP8.5, RCP4.5, A2, A1B, B1) regarding seven countries of the Central Africa to reveal
that the climate change effects were significant in the study region. The results showed that, the
mean monthly cooling energy demand in household is estimated to be 123.3 degree days (DDs)
by 2046 and 192.4 DDs by 2100. The highest energy value demand was recorded in Chad. The
average annual expenditure on health was estimated from US$520/capita in Gabon. According to
scenarios RCP4.5 and RCP8.5, the mean monthly cooling energy demand in residential buildings
will increase to 81.6% and 167.3%, respectively, by 2100, as compared to that in 2016 in the
Central African countries. The impacts of climate change are not still the most important in the
regions with strong CO2 emission.
