Mosque energy performance : part I : energy audit and use trends based on the analysis of utility billing data

Abstract EN

Mosques are distinguished from other types of buildings by having a unique function characterized by an intermittent operation schedule.

Within a given area and time zone, mosques are operated simultaneously, which could have an impact on the demand for energy particularly in areas that are highly dependent on mechanical airconditioning, and/or heating for achieving thermal comfort.

The importance of achieving thermal comfort in mosques to enable worshippers perform prayers in a spiritual environment with minimum energy requirements ; make the thermal design and operation of energy systems in mosques critical parameters in determining their performance.

The analysis of electric energy bills data is a feasible and useful approach in showing the general trend and the history of energy use.

The billing data can provide a reasonable estimate of the overall annual electric energy use in mosques.

This study presents the analysis of five-year electric energy billing data for five typical mosques in the hot-humid climate of the eastern region of Saudi Arabia.

The aim is to assess and compare energy use trends over time of different types of mosques as a step towards a comprehensive study of their energy systems, overall thermal performance and operation strategies.
