Design strategies for a Big Mosque to reduce electricity consumption in Kingdom of Saudi Arabia

2017

This study proposes and analyzes the design approaches for a Big Mosque to conserve electricity consumption in Kingdom of Saudi Arabia. Mosques are characterized by a unique function and operating schedule that are not typical to other types buildings. In this study, the effects of zoning and partitioning are investigated. To demonstrate the effectiveness, one of the Riyadh city grand mosques is identified as a model to explore the most appropriate ways to conserve energy. Three cases are simulated by eQuest which is designed to perform detailed analysis of sophisticated building energy use. First, the mosque with inefficient materials, second the mosque with effect materials and without zoning and finally the mosque with zoning and efficient materials. Simulation results show that some of the important energy conservation techniques should be applied in the construction phase.

Evaluating the potential energy savings of residential buildings and utilizing solar energy in the middle region of Saudi Arabia – Case study

Energy Exploration & Exploitation

Lately, with the growth in energy consumption worldwide to support global efforts to improve the climate, developing nations have to take significant measures. Kingdom of Saudi Arabia (KSA) implemented meaningful policy actions towards promoting energy efficiency (EE) in several sectors, especially in the building sector, to be more sustainable. In this paper, various EE measures and solar energy prospects are investigated for the residential sector, in two locations in the middle region of the KSA. An energy performance analysis of pre-existing residential buildings with an overall design is performed using simulation programs. However, installing EE measures in the building envelope is important to achieve an efficient sector regarding its energy consumption. The findings showed that applying EE measures for the building envelope, walls, roof, and windows should be considered first that makes the energy conservation possible. In Riyadh, EE measures are responsible for reducing ene...

AN INITIATIVE TOWARDS TRANSFORMING MOSQUES IN EGYPT TO BE ENVIRONMENT FRIENDLY AND ENERGY SAVING

From the simplicity and energy-efficient early mosques that utilized daylighting and natural ventilation, our existing mosques had transformed to intensive energy consumers with the tendency of Muslims to supply their worship places with huge air conditioners and chandeliers. As more and more energy demanded each year, the government has to build and operate new power generation plants and to import the required fuel making the foreign currency situation worsen. This contradicts with Egypt's ambitions towards fulfilling its sustainable development vision 2030. Egypt resides more than 100,000 mosques that consume huge amount of energy regarding behavior of Egyptians towards wasting their resources, including energy. Al-Azhar, with its pioneering role in the Islamic world, can initiate an action plan towards greening 100 of the existing mosques as a pilot project. This research work discusses topics like LED lighting, controlling air-conditioners, use of renewable energy (solar), controlling ablution water, and other energy saving measures, together with awareness plan depending on the Islamic spirit towards conservation. The research work suggests also funding mechanisms for transforming our mosques to be environment-friendly and energy saving mosques. A case study of a mosque in Alexandria is considered to illustrate the proposed procedure.

The Economics of Using Solar Energy: School Buildings in Saudi Arabia as a Case Study

ARO-THE SCIENTIFIC JOURNAL OF KOYA UNIVERSITY

As a result of increasing population and building of new schools in Saudi Arabia, the demand for electricity is growing rapidly. In this context, the utilization of renewable energy resources such as solar energy appears to goal since it is abundant and holds huge ecological and economic promise. This study aims to provide a new entrance in school buildings’ design and construction by studying the current situation of energy consumption, the possibility of using solar cells, and the economics of its exploitation in school buildings. Interviews were conducted in school buildings at different levels in Arar city as a case study to collect data on energy consumption. Furthermore, a base case school building was selected for studying detailed energy consumption, and then, photovoltaic (PV) energy was proposed to use the on-grid system in accordance with governmental regulations. The study concluded that the use of PV energy in school buildings is economically feasible in addition to tha...

Architectural Sustainability on the Impacts of Different Air-Conditioning Operational Profiles and Temperature Setpoints on Energy Consumption: Comparison between Mosques with and Without HVLS Fan in the City Center Mosques

Journal of Design and Built Environment, 2021

The use of air-conditioning (AC) in conjunction with high-volume, low-speed (HVLS) fan has become a trend in retrofitted mosque buildings in Malaysia to improve thermal comfort conditions. However, the energy impact of operating AC and HVLS fan simultaneously is unknown. This study compares the annual energy consumptions between mosques with and without HVLS fan installed and investigates the optimum temperature setpoints and operational profile to improve the mosques' energy efficiency. The comparison using the Building Energy Index (BEI) did not clearly show the superiority between the two groups in terms of energy performance. The study found that both studied mosques could produce around 1-4.9% energy reduction when the AC temperature setpoint was increased by 1˚C and could result in the highest cost-saving of about 4.9% when the temperature was set at 27˚C. A 30-minute AC operation during each daily prayer, except Subuh, could save between 14.8-16.7% annual energy consumpti...

Review on Solar Space Heating - Cooling in Libyan Residential Buildings

Solar energy and sustainable development, 2018

This review paper focuses on documenting and studying published papers and works in the field of solar heating and cooling air space in residential buildings. The goal of this survey and documentation is to find out the most important flushing results and conclusions specifically in fields of using solar energy for space heating, cooling and ventilation of local residential buildings in Libya. This covers using active and passive solar systems in, achieving thermal human comfort in such buildings leading to reduce electrical energy consumption. This paper also concentrates on applying energy efficiency measures in buildings; planning, design, and construction stages with the use of the principles of energy conservation in buildings. There are several studies comparing traditional with modern house designs in several local cities including both famous old cities of "Ghadames" and "Gharyan". Several conclusions and recommendations are summarized within the text of ...
