Abstract
Global energy use has risen due to increased demands and inefficient grids in
developing countries. Energy saving is detrimental in countries in which their energy supply
capacity is lower than their demand. Energy Efficiency Measures (EEMs) can easily be
incorporated in new buildings; however, existing buildings have limitations in geometry,
orientation, and materiality which restrict their applicability. This research analyses the
efficiency of applying several EEMs in the residential stock in hot semi-arid regions to reduce
their energy demand. A typical residential house in Duhok, Iraq was selected as a case study.
The EMMs efficiency was analysed using building energy simulation. As heating and cooling
loads have similar contributions to the house thermal demand -with 56% and 44% respectively,
the potential energy reduction considered both loads simultaneously. The optimal combination
of EEMs can reduce the thermal load by 48.7%, while individual passive measures can only
reduce the thermal load up to 16%. In urban scale, the energy reduction potential presented in
this paper would represent a shift from a heating-dominated scenario to a cooling-dominated
one. This in turn would aid in decreasing the energy demand during winter months in which the
largest energy shortages in the city are registered.
