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.

The high strength-to- weight ratio of titanium alloys allows their use in jet engines. However, their use is restricted by susceptibility to oxidation at high temperatures. In this study, the possibility of increasing the operating temperature of titanium alloys through using Yttrium Aluminum Oxide (YAG) as a thermal barrier coating material for Ti-6Al-4V substrate is studied. The study concludes that YAG can be utilized to increase the operating temperature of Ti-6Al-4V titanium alloy from around 350 °C to 800 °C due to its low thermal conductivity and phase stability up to its melting point. In addition, its lower oxygen diffusivity in comparison with the standard YSZ material will provide a better protection of the titanium substrate from oxidation. In this work, coating was created using atmospheric plasma spray. X-ray Diffraction (XRD) and Scanning Electron Microscope (SEM) were used to examine coatings' composition and structure. The coating was characterized by thermal shock test, Vickers hardness test and adhesion strength test. X-ray diffraction indicated that the coating was of a partially crystalline Y3Al5O12 composition. The coating was porous with excellent thermal shock resistance at 800 oC, with a Vickers micro-hardness of 331.35 HV and adhesion strength of 17.6 MPa.

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.
