Phase change materials are used to decrease energy cost, dependency on fossil
fuels and make the buildings energy efficient. The main aim of this study is to
carry out parametric study in BWh zone of Koppen-Geiger climate classification in
order to evaluate the hypothesis that a single PCM or a group of PCMs (in the
narrow) can be used for the whole BWh climate zone. Hence, the energy
performance of two-storey PCM integrated residential building located in eight
different cities (Abu- Dhabi, Dubai, Faisalabad, Mecca, Jodhpur, Nouakchott,
Cairo and Biskra) from BWh Koppen-Geiger classification was evaluated using
the most representative building envelope. Also, the impact of meteorological
factors like temperature, wind speed, relative humidity, solar radiance on energy
saving have been evaluated. Numerical simulations were performed with thirteen
different phase change ranges in DesignBuilder software, which uses EnergyPlus
as its calculation engine. According to the test results, the optimum PCMs were
able to reduce the temperature fluctuations and the maximum temperature reduced
by up to 4.64C. The monthly energy savings results showed that different PCMs
were found to be optimum in different months of the year. Except for Cairo and
Biskra,
