This paper discusses sustainable strategies have been implemented to improve the energy performance
the housing sector in arid climate, especially villas. A practical case study along with ﬁeld measurements
is presented in order to highlight the behavior of the energy performance after implementing
conservation measures in practice. The residential sector in arid climate especially in GulfCountries
has a signiﬁcant share of carbon emissions. Millions of householders occupy villas and town houses.
harsh hot weather of this region is one of the reasons for a high demand on the cooling energy and the
consumption in the housing sector. Thus, there is a real potential to retroﬁt the existing houses
practical energy conservation measures. These techniques are affordable and feasible economically.
they play a substantial role to increase the energy efﬁciency of the residential units on the demand
This study discusses the results of 12 months were monitored after implementation of energy savings
measures on selected 10 villas in the capital of UAE – Abu Dhabi. This research highlights different
by each villa against the implemented energy savings opportunities. The target of these executed
strategies is to improve the energy performance of these selected villas after conducting a detailed
assessment and implementing its recommendations. A detailed analysis of the electricity performance
of the baseline and the monitoring period has been performed by using the actual readings
the existing power meters according to the international performance measurement and veriﬁcation
This research presents the energy data for the entire year before and after the implementation
the energy conservation measures – ECMs. These ECMs show the potential of improvement of energy
in the housing sector by increasing the energy efﬁciency by 25.1% in average through low
medium cost techniques. The percentage of savings varies from 14.4% to 47.6% of the total electricity
to the individual operating conditions for each villa and the behavior of occupants. As a result,
contribute reducing the carbon and GHG emissions, and open new perspectives of energy savings
housing sector in arid climates.
