Abstract

ABSTRACT
Energy efficiency is a core of energy and environment policies, introducing a lot of
benefits, containing many opportunities to decrease energy consumption, bill cost,
fossil fuels and CO2 emissions.
In Egypt, there are more than 115000 religion worships. Many of them are very
inefficient when it comes to energy use.
The main step to implement EE options is energy audit.
The energy audit is carried out for a lot of RWs. It includes: observing the natural
lighting, analysis of past energy bills, list for the type of loads (lamp, AC, fans, and
water heaters), define savings potential, energy cost saving actions, reduction in gas
emissions, and calculating the payback period.
Within RWs lighting makes up a significant part of electric energy consumption.
Therefore, EE lighting technologies have been targeted by efficiency programs. There
are many advanced energy saving technologies like; electronic ballasts, fluorescent
tube (T5), and light emitting diodes (LEDs).
The most significant thing achieved by the auditors was the amount of money that will
be saved due to implement options as lighting improvements and air conditioning
control. The Egyptian Electricity Holding Company supports all customers, commercial,
governmental, public utility…..etc. sectors to implement EE standards and codes for
electric equipment and appliances.
This paper focuses on using LEDs for interior and external lighting of RWs, to verify
the necessary illuminance, comfort conditions and energy savings.
The paper also presents: Training, capacity building and awareness for preachers,
routine and preventive maintenance, simple, low cost and long-term energy saving tips
that every RW can do to conserve energy, save money and reduce CO2 emissions,
lighting power density, the maximum lighting power per unit area of a building and
classification of space function.
