Published: December 2019

Abstract
The Luk Barat Bridge has an important role in transportation infrastructures in the North Lombok District, connecting cities in Lombok Island. Unfortunately, the bridge is located where the most vulnerable area in Lombok Island, as earthquakes occurred in 2018 have ruined almost one third of the island and destroyed thousands of buildings. The bridge has been deformed after the earthquakes. Geodetic measurement showed that the bridge has displaced in total of 0.36 m measured from the datum point of BM2 near located closed to the bridge area. Numerical modeling also indicated a similar value of displacements.

Abstract
The tectonic setting of Indonesia is very complex due to its location on the boundaries of several major tectonic plates. The complexity of the tectonics also makes Indonesia prone to natural disasters such as earthquakes, tsunamis, and volcanic eruptions. Crustal deformation caused by the tectonics activities can be monitored using geodetic techniques such as Global Positioning System (GPS) and Interferometry Synthetic Aperture Radar (InSAR). In this research, we analyze the crustal deformation in the northern part of East Java using ten GPS Continuously Operating Reference Stations (CORS) data provided by the Indonesian Geospatial Information Agency from 2015 to 2018. The results showed the horizontal movement toward the southeast for all the stations. The horizontal velocity rates are range between 2.62 cm/yr observed at CPAS site, and 3.173cm/yr observed at CNGA station. For the vertical displacements, all the sites are subject to subsidence with the rates range from - 0.021cm/yr to -0.4 cm/yr that we suspect related to the geological settings of the study area. However, we found that the vertical annual time series of CMJT stations in 2015 are not consistent; this is because the antenna type was changed on the day of year (doy) 286 in 2015. On the other hand, the strain analyzes in the study area showed considerable compressional strain in the segment formed by three stations, namely CTBN, CSMP and CSBY which are located near to the Kendeng active fault.

Abstract
Energy consumption in Egypt’s buildings has increased considerably with the growing need to achieve thermal comfort conditions inside buildings. The continuing increases in both residential and commercial buildings require an increase in power generation meeting the new demand. Energy consumption in buildings increases yearly due to the increase in HVAC systems operating hours. It is desirable to minimize the energy consumption and to promote the use of renewable energy resources, saving the earth from global warming effects and the depletion of the ozone layer. In hot and humid climatic regions, high temperatures with high humidity levels results in humans’ discomfort leading to high HVAC energy consumption. In order to understand the energy performance in Egyptian hospitals as they have special requirements and massive energy consumption of HVAC equipment, medical equipment, lighting and infection control systems a hospital located in Alexandria, Egypt was chosen as a case study. The study aims to investigate the energy consumption in Egyptian hospitals and to evaluate the energy-saving efficiency of an existing building. A model for under construction hospital was created using DesignBuilder simulation tool. The initial model was validated based on the hospital construction and mechanical consultants’ data. The initial model was then retrofitted firstly to the latest outdoor design conditions and weather file data recommended by ASHRAE and NREL. Energy efficient techniques affecting annual HVAC energy consumption and whole building energy were investigated. The study provides information for energy efficiency improvements in Alexandria, Egypt hospitals helping designers managing energy in buildings reducing the energy consumption sufficiently. A new DOAS was implemented for temperature and humidity independent control of HVAC system showing significant energy saving in both HVAC and whole building energy consumption. This research recommends a new energy models for future hospitals in Alexandria, Egypt improving the energy efficiency in Egyptian buildings.

Published: December 2019

Abstract
Macro-Climate and Micro-Climate conditions have a great influence on energy consumption and thermal performance on both urban and architectural design scales. Integrating the passive strategies and measures are considered the best ways of dealing with different climatic conditions.
The geometric shape and orientation of the buildings lie at the core of the passive strategies that significantly affect the thermal performance and energy consumption of buildings. From that end, the research aims to evaluate the thermal performance of different geometric shapes and orientations of residential buildings. The research adopts the analytical approach through the simulation of different possible scenarios using of building shapes and orientation using comprehensive environmental software “Autodesk ECOTECT”. It aims to achieve the best possible configuration that exhibit best thermal performance for use in residential buildings in the region of Tebessa (Algeria).
The results indicate significant thermal effects due to proportions of building’s shape and its orientation. Therefore, this research recommends applying passive solar design strategies, particularly with respect to the geometric shape and orientation recommendations in the first stage of the design process. The proportions of the building must be determined with a complete understanding of their impact on thermal performance and energy consumption.

Published: December 2019

Abstract
The direction towards sustainable development challenges the designers to explore energy-efficient designs to provide adequate levels of natural daylighting. Indeed, using computational simulations can offer valuable performance predictions; still, exploring all possible combinations of design variables is a tedious and time-consuming task. This type of problems also doesn’t yield straightforward mathematical forms, and using black-box optimizations is more useful. This paper presented reviews, methodological tools and measures to help designers evaluating the potential contribution of simulation-based metaheuristics to optimize the design of façades in such obstructed contexts. The tested metaheuristics algorithms showed promising potential to attain optimum solutions, though the results confirmed that Genetic Algorithm is not sensitive to population size for optimizing façade design problems, as it obtained optimum designs only after conducting several runs of simulations. In contrast, Particle Swarm Optimization exhibited a higher sensitivity towards swarm sizes, where it converged much faster with larger swarm sizes; and a better performance could be achieved when the swarm size was 10 times the number of design variables alongside 0.2 particle’s velocity. This implies that metaheuristics optimization can be used along with simulations as accelerated tools in the early stages of design to rapidly predict building performances in obstructed environments.

Abstract
Over the ages, Egypt has been known for its flourished history with the ability and the power to fascinate mankind. Its great heritage appears in several forms that include monuments, tombs, temples, and documents revealing past events, but until the beginning of the 21st century only a minimum share of the secrets and the mysteries were exposed. Egypt’s monuments are deteriorated and out of the spot and has been left without maintenance and development. Numerous monuments and historical sites are ignored and not even considered as a destination for tourists because of the absence of virtuous marketing and propaganda. The planning and management of cultural heritage buildings through digital 3D models has become a necessity to protect and conserve the existing history. Building Information Modelling BIM is considered a main tool adopted by the Architecture, Engineering and Construction AEC sector for its qualities and capabilities. Due to the complexity of cultural heritage buildings the concept of Heritage Building Information Modelling (HBIM) which concerns the modelling, documentation, and virtualizing the heritage. This research will focus on the use of HBIM technology by implementing augmented reality mobile application to upgrade the quality of branding of historical sites in Egypt. The AR will augment Al-Baron Palace, which is the chosen case study. The methodology adopted is literature review, comparative analysis on international case studies of sites that applied augmented reality, and an experiment followed by a questionnaire answered by users to evaluate the usage of such mobile application. The research will conclude with a framework that will provide guidelines for applying augmented reality technology system in order to enhance and promote Egypt’s heritage.

Published: December 2019

Abstract
Daylight is vital to building occupants as it impacts health and productivity of humans in the indoor environment. No doubt that green building rating systems contribute to the awareness of the significance of daylight in buildings, they enhances the indoor environmental quality by awarding credits to daylight harvesting in buildings. LEED as one of the predominant green building rating systems sets specific daylight criterion, and offers more than one option for project teams to assess and comply with the set criterion; either using manual calculations, using computer simulation (during design), or by daylight measurement (by substantial construction). This article presents a case study of a LEED Gold building in Cairo, Egypt. Within this specific case, three daylight assessment approaches were implemented; Daylight simulation (on design drawings), daylight measurement (after substantial construction), and Post Occupancy Evaluation (POE) (after 9 months of building occupancy). This paper contrasted the results of the assessment methods, this contrast in daylight assessment methods revealed the significance as well as drawbacks of each assessment method compared to the other, and distilled valuable insights about the reliability of each of the available assessment methods.

Published: December 2019

Abstract
In architecture pedagogy, the architectural design process is a creative one. It relies on the ingenuity of the student to use all key issues of a building problem and interpret them as spatial elements, which are incorporated within the building design. The emphasis on the environmental design of buildings is a significant step due to the increasing awareness of the use of passive systems and strategies. Thus, students face increased pressure to design buildings with solutions toward environment. This paper presents a descriptive study that investigates the utilization of simulation tools in the design process to enhance the learning outcomes and allow students to become sensitive contributors to the strong link between environment and architecture. The study focuses on the tools deployed by students from studio-VIII, in the college of architecture and design at Effat University, to embed passive performance techniques during design problem solving. The paper identifies the tools students used, and the impact of using them on selective projects. Moreover, the paper applies a questionnaire among the targeted students to investigate how simulation could inform their design through different stages of the design process starting from the pre-design studies to the final feedback on their design. The findings illustrate how simulation tools were used integrative to building design. The selected projects identified some of the challenges faced by students to incorporate simulation methodologies during a routine design studio process and it advocate considering the design problem-solving patterns and preferences in the improvement of environmental design.

A Design Chart to Determine the Well Efficiency and the Maximum Spacing of Skylights for Daylighting as a Function of the Skylight Well Width
Authors: Saifelnasr Shady Shawky 
Published: December 2019

Abstract
The main objective of this paper is to introduce a simple tool for architects, represented by a design chart to find out the skylight well efficiency (WE) and the maximum skylight spacing (x), needed when utilizing top-lighting for daylighting as a function of the skylight well width (w). That would lead to suitable geometry and spacing of skylights inside a given space which directly affects the distribution of daylight, leading to better quality of light. The proposed design chart is used to find the skylight well efficiency (WE) and the maximum skylight spacing (x) of patterned skylights needed for ensuring proper admission and distribution of diffused light, i.e. quantity and quality of daylight. It consists of two parts and both parts consist of a number of graphs combined together, representing the different included variables that affect either the skylight well efficiency (WE), or the maximum skylight spacing (x) with a given skylight well width (w). Those graphs were developed by the author using different formulas except one graph that was previously designed and has been adapted by the author to be combined with the other graphs.

Published: December 2019

Abstract
Energy Energy consumption in buildings is approximately 40% of the total world annual consumption. In hot climate, crucial percentage of energy consumed due to the cooling loads in buildings. Wherefore, tendency towards decreasing the energy demand rises through the revival of passive strategies and encouraging the development of innovative initiatives in different fields. Double skin facade (DSF) is a promising passive strategy to enhance the thermal comfort while decreasing energy consumption. The DSF promotes the convective strategy in the cavity as an additive force to enhance air movement the occupied spaces. The study will introduce a proposed skin inspired from parametric pattern movement and exploit the features of the pattern mutation. The movement of the parametric pattern demonstrates changes in the cavity configuration revealed at the outer skin through the entire height of the façade. The proposed facade generates a special species of fluctuation for air distribution covering larger area of the occupied space by applying the principle of Venturi's effect. The results show enhancement in the magnitude and distribution air velocity inside the occupied space, which assists in improving thermal comfort range inside by natural means.
