Containing and then reducing greenhouse gas (GHG) emissions require designing energy efficient buildings which save energy and emit less GHG. Orientation has an impact on the building’s overall thermal performance and designing heating and cooling to reach occupants’ thermal comfort. Correct orientation is a low cost option to improve occupant's thermal comfort and decrease cooling and heating energy. An appropriate building orientation will allow the desirable winter sun to enter the building and allow ventilation in the summer by facing the summer wind stream. In this paper, a building module in Jordan will be assessed using Design Builder Simulation packages to find the effect of the building orientation on the overall thermal performance. It was found that the larger windows should be in the southern walls in the northern hemisphere to provide the most heat to the building through the window which allows the sun in winter to enter the building and heat it up. This will reduce the amount required for heating by approximately 35% per annum.

Understanding the Template IEREK press provides its authors with templates mandatory for submissions. Easily download the Author Instructions template and direct any questions you may have to the Editor-in-Chief or simply follow the steps below. Author General Guidelines A paper is to be formatted in an APA Style that is as long as 6 to 8 pages. The paper is to begin with an abstract text and a word count that falls within 100 to 300 words. The recommended font for the whole paper, or rather the general text, should be Times Roman 10 pt. Headings should be 10 pt, bold, and numbered. The template starts by providing authors with information on the placement of each section. In other words, the structure of the article is laid out starting with the abstract. The template then requests from the author a number of keywords relevant to the topic/field discussed, as they assist researchers in finding your paper when conducting their own.

The shortage of sufficient available fresh water resources in Jordan to meet water needs forces the nation to look for new water supply sources also to meet the increasing demand for fresh water. In this manuscript, a case study for designing, optimizing and implementing an off-grid water desalination system using photovoltaic (PV) power generation system is introduced. The system is installed on a farm in Southern Ghore of Jordan valley where the access to the grid is not reliable enough to guarantee the desalination of the amount of water for the farm’s irrigation needs. The study offers a framework to aid in designing similar pilot plants where the classic power generation prediction is greatly affected by the environmental conditions. An off-grid PV system with a total nominal power of 10.4 kWp was designed, procured and installed in the southern part of Jordan Valley near Karma town. The system operates the pumping system as well as the reverse osmosis based desalination unit. A measurement system has been collection relevant data like temperature, radiation, voltage, current, water quality, pressure, etc. continuously for the last 4 years. In this paper we will present the sizing procedure used, the system design and evaluate the design using the collected data of the run-time of 4 years. Data about the water quality and amount of desalinated water will equally be used to evaluate the system. The paper will end with recommendations to adapt the system design in different part of the Middle East and North Africa (MENA) region.
