Nowadays many of social housing in Alexandria are often obsolete with inadequate condition
that represent through the comfort conditions, energy consumption and structural conditions
moreover the lack of the minimum aspects of the architectural aesthetic elements. over 50% of
the Egyptian population live in informal settlement. Alexandria has a great share of these slums,
while it contains more than 36 informal setlements. The residential sector consume about 47%
of all the electricity consumption. The government constructing a large concrete blocks without
concerning about the environmental issues during the decision making or design buildings more
energy efficient. Also this buildings with old energy technologies affects the overall energy
consumption in the city. this research aims to state the significance of choosing the appropriate
software in decision making for retrofitting strategies of building energy and micro climate
simulation through formulating a strategic framework of concentration area, selection and
assessment criteria applied of different architect friendly softwares, concluding by applying the
passive design strategies reaching the most effictive thermal comfort techniques through
coupling method in order to simulate the building energy and micro climate by eQuest which
employs DOE-2.2 and Designbuilder which employs Energyplus along with the micro-climate
tools such as CityBES and ENVI-met respectively as the most architect friendly use softwares.
