Published: March 2019

New generation Polymer-filled and jacketed wireline cased hole cables eliminate all inherent bottlenecks of traditional wireline logging cables, enabling unprecedented operational efficiency with substantial reduction of well control risk and costly maintenance. This Technology enables a Mexico operator to deliver all their Operator Field wells ahead of time, without any HSE or well control incident while gaining 9 days of early production.

Recently developed Polymer encapsulation and bonding technology completely seal Wireline cables electrical core and armors. The result is elimination of armor birdcaging (see glossary) and stranding, grease injection and associated equipment, cable gassing-up and well fluid related armor corrosion. Total armor torque balance and polymer outer jacket substantially reduce Chrome or glass coated completions damage, cable friction and maintenance requirements. The result is unprecedented well control safety, grease related environmental and reservoir damage elimination, higher operational efficiency with faster rig-up/down and tripping speeds, reduced tractor conveyance needs with improved well access in complex completions and proven early production gains.

Contrary to conventional Wireline cables, the new generation polymer encapsulated cables come with a gas blocked core and a pressure balanced sealed cable termination. Potential well fluid migration through the cable cross section is thus completely prevented. Along with the polymer jacketing, well control risk is all but eliminated. During 2018, and for the first time in Mexico, 45 cased hole interventions, 130 descents and more than 1,000,000 feet in the well polymer cable deployments were carried in a North Mexico gas field. All Perforations, Production logging and other cased hole descents were completed totally free from HSE, operational or well control issues. Logistically challenging cable maintenance trips were all but eliminated, saving substantial time and cost to all parties involved. Compared to conventional wireline operations, time saved using polymer encapsulated Wireline cables represented a 50% reduction in rig-up and rig-down time, as well as 40% operational efficiency gain. With wells delivered early to production all contractual targets were exceeded, adding 9 days of additional production of gas and condensate.

New generation Polymer encapsulated wireline cased hole cables have enabled the Mexico Operator plan and carry out efficient, safe, cost effective, and environmentally friendly Wireline Cased Hole operations, delivering producing wells ahead of time and exceeding contractual requirements.
Combined Plug Setting and Multiple Sleeve Shifting Electric Line Operation to Deliver a Precise, Highly Effective and Efficient Intervention Solution
Authors: Murchie Stuart , Magnussen Odd Einar , Haaland Stian , Sætrevik Martin
Published: March 2019

A plug needed to be set in a well located in the Norwegian Continental Shelf to shut off an existing production interval, followed by the opening of several pre-installed reservoir control sliding sleeves, in order to optimise oil production from the well. It was suggested by the service company that such a two- run operation could be combined into a single run to save time and cost.

An electric line deployed solution was designed to ensure high accuracy and control across the combined operation, providing power to both the plug setting and sleeve shifting tools, along with real- time command and toolstring status readout at surface. The combined setting and shifting functionality required the use of a through-wired shifting tool to enable real-time activation of the plug setting tool, which was positioned below. A bi-directional shifting tool was used, which, in conjunction with a bi- directional stroker, would enable sliding sleeve shifting in both directions, if required, during the operation. Furthermore, its dogs were retractable on command to ensure no inadvertent shifting occurred while traversing the multiple sleeve positioned in the well.

Pre-job system integration testing was done at the service company location using a mock up completion comprised of two sleeves rigged up with a tubing joint in a horizontal set-up. This tested that there was no incompatibility between the plug setting and sleeve shifting components of the combined tool string, and that no inadvertent tool hang up occurred within the completion.

The toolstring was run in hole, depth correlated and the plug set and released. Subsequent correlation was then done for the sleeve section. The real-time control and surface readout of stroker force and position enabled a precise sleeve shifting operation, and all sleeves were shifted successfully as per requirements.

The stroker also provided a means of pulling the plug when it got inadvertently stuck whilst running to set depth and the electric line winch was unable to pull the string free. Multiple release subs were also positioned in the toolstring to enable independent recovery of the plug and stroker assembly if required. In addition, a memory pressure/temperature gauge was run, which provided further validation of sleeve shifting upon download and analysis. A tractor was used to convey the toolstring across the highly deviated section of the well.

This single-run combined service solution delivered flawless operation with considerable time savings.
Digital Slickline: Case Studies Setting and Pulling Crown Plugs
Authors: Heaney F. M. , Smith C.
Published: March 2019

As the scope of deepwater operations increases, the need for cost-effective well servicing is paramount, particularly because of the continued challenges associated with current volatile commodity pricing. One of the first requirements on any subsea deepwater intervention with a horizontal wellhead production tree is pulling the subsea horizontal tree isolation lock mandrel plugs, commonly referred to wellhead or crown plugs. This can be a "show stopper" event if not planned correctly. Because of the critical nature of this action, the majority of operators follow a two-prong approach, with a primary plan of action and a contingency procedure, to help ensure barrier removal proceeds as planned. Although successful removal of the crown plugs is the principal concern, it needs to be completed cost-effectively for the intervention to obtain approval.

The advent of digital slickline (DSL) allows surface readout (SRO) monitoring during the removal and installation of these barriers to provide an increased level of confidence during this important phase of the operation. This paper outlines case studies of the real-time sensors available with the RF communication DSL system that was highlighted previously (Heaney et al. 2018) for pulling and setting these wellhead or crown plugs in deepwater Gulf of Mexico interventions using the traditional jarring approach. Two brands of crown plugs are available on the market, and although both pull the same, there is a difference in the installation procedure and each plug or lock has a unique SRO digital signature.

Additionally, the straight pull battery operated extended-stroke downhole power unit highlighted in McDaniel et al. (2008), Clemens et al. (2014), and Babin et al. (2015) offers a cost-effective contingency that can be deployed on the small-footprint DSL unit. This setup allows starting the operation using the traditional jarring approach, and if required because of high hydrostatic forces, the operation can easily move to a straight pull contingency without rigging down the DSL unit for maximized wellsite efficiency.

New developments as the downhole power generator was ported to DSL are discussed, notably on- command motor controls and SRO, which was traditionally only available in memory. A downhole anchor was added to the toolbox, which can be run in combination with the downhole power generator to expand effectiveness, as new production trees might not allow for a no-go landing shoulder. To address the increased water depths, the 3.59-in. extended-stroke downhole power generator was upgraded to 80,000 lbf pulling force.

Thru-tubing uphole re-completion is a workover technique aiming to re-complete the existing wellbore by temporary abandoning the lower producing zone and subsequently perforate upper layer. There are various techniques used to temporarily abandon the lower zone worldwide. Specific to Caspian Sea development, the temporarily abandonment will only be required to set an isolation plug. However, statistically speaking, success ratio of lower zone temporary abandonment, is quite low using current plugs set in different condition of completion. In addition, the risk of deploying balance cement plug also presents significant challenge due to interval limitation between top of the cement and new perforation interval. It is deemed necessary to find a fit-for purpose solution that provides a solution to the Caspian Sea environment plug and temporary abandonment strategy. A new plug technology, metal to metal system, was introduced to provide assurance isolating the lower zone prior to perforating new upper zone. Subsequently, a wireline deployed or pipe (tubing) conveyed perforation is not an attractive solution to thru-tubing up-hole recompletion technique. A new technology to perforate lively is selected from safety and economic point of view for this specific well. The perforation was done in underbalance condition with intelligent coiled tubing. The uphole re-completion (well delivery) performance was more attractive than other conventional uphole re-completion techniques. This paper will elaborate the success of recompletion techniques by deploying multiple new technologies in the Caspian Sea.
Heritage Resources as a Method to Reviving the Identity of Contemporary Interior Designs A Comparative Analysis of Users' Preferences of Interior Space
Authors: Elnaggar Hala Barakat
Published: March 2019

Egyptian heritage is known to be a result of many great civilizations. With various traditional elements and special features that add prominence to its cultural aspects, it carries magnificent aesthetic values and visual forms. Nonetheless, and due to the different nature of the cities and provinces in Egypt, styles and features in each region have taken different paths. For instance, Ancient Egyptians influenced some areas while others were more affected by Islamic or Coptic civilizations. Some regions were preserved in Nubian folk art heritage form. In the past, the country had a clear and unique identity that reflected its characteristics, environmental benefits and socio-cultural attributes. However, today the identity is faded and is nearly completely wiped by Western notions erasing our ideas, identities, and thoughts. This study focuses on the elements of heritage, their impact on people and the way these elements inspire interior architecture, form and psychology.This study aims to discern the elements of heritage and identify the character and special criteria of each civilization such as the Ancient Egyptian, Islamic and Nubian folk art heritage with special references and clarifications as to the criteria of reviving the traditional identity in contemporary interior design. This study will also include an analysis of user preferences in relation to discussed features.

The Invisible Painting Art between East and West
Authors: Mohamed Hosam Abd Elkader Metwally
Published: March 2019

The Art of painting relies on the employment of the painting's vocabularies in an idiomatic meaningful format under the framework of the dialogue form. Such methodology occurs at times and in a new style to create new systems and formats at other times (Form Structure). The dilemma lies between these two frameworks where there are reality and mind, sensory and mental or visible and invisible, that is, between what is perceived by the eye of idiomatic semantics forms and what is realized in accompanied suggestive or figurative meanings.The interpretation of the invisible in the vision of Oriental Art is different from the vision of the western art because the spirit of the culture is manifested in the first to incorporate the individual in the group. As in the universe, it removes intervals so that the individual may seem similar to his surroundings in order to reach the infinite and unlimited aspect. This vision is based on a type of intuitive knowledge in the form of detection or discovery, which is based on the dualism of the visible and the invisible. Therefore, the receiving process is unlimited to the aesthetic pleasure that focuses on the form alone, and it is an existential process that is based on the dialogue between the receiver and the artwork. Islamic Sufi aesthetic thought tries to find the sensory effects in the universe. It is not concerned with the mental abstract perceptions of geometric shapes associated with the western logic." Islamic abstraction would not seek to meet the formal requirements such as a mathematical current of Mondrian or freeing the spirit of the form extracted from the content, internal necessity of the structure or the internal empathy for the colors and meanings. It does not intend to reach ideal purity in the form so as to realize the artistic feeling in Malevich. It tries to find natural laws, including geometric shapes ,and then its loads them with facts and meanings towards the absolute. It results in a new standard vision that will create another independent reality which does not end with just watching the painting so as to combine the idea with the artistic vision to denote the meaning"(Abu Elmaggd, 2011).

Authors: Saleh Reem Assem
Published: March 2019

Within each culture, the multi-source origins play an essential role to form its distinct moral and aesthetic values, which emphasize the cultural identity. These values were accumulated through ages. That’s why every single cultural tributary should be traced, to demonstrate the extent of its impact on specific city identity formation.The Egyptian government pays due attention to Siwa Oasis because of its special historical and cultural characteristics. It happens in co-operation with one of the Culture Ministry sectors "the General organization for Cultural Palaces", that adopted the idea of reviving the project of city studios. Such initiative has been established before at the city of Luxor. For example, a financial and logistic support was provided for the initiative in a similar context.From this standing point, this paper provides a historical study about Siwa Oasis since its inception at the Ancient Egyptian era and through the Greco-Roman, the Coptic-Islamic era, and the Arab influences till now. Also, I will review the Siwa studios grant: procedures, different sessions and the most interesting aspect of it, which is the exhibitions.The historical and cultural overview will include: the Significant monuments in the city, location and environment, population and their language, traditions, and custom, and finally, the Siwa Oasis features nowadays.Reviewing the project stages will include: how to apply? On what bases the participants was chosen? Also, information about the time schedule, the site-visits, etc. Finally, I will analyze some artworks from 2009 till now in order to emphasize the importance of such activity on the cultural map.

The popular festivity known as Corpus Cristi is a clear manifestation of culture in Ecuador. It is considered a crosscultural expression of the cosmovision and iconographic symbolism of religious fusion making an evident imaginary connotation of the population. Where evident, catholics are of a vernacular world and end up being a praise in honor of the favors received from the Body of Christ and the indigenous roots of spirituality. It represents gratitude for the successful harvests obtained in the year by the Pachamama and Taita Inti. The present study aims to provide furnishings with designs of this festival, the park 13 de abril in Pujilí, which is also commonly known by locals as the Danzante Park. The methodology used was an analysis of the artistic projects developed by Panofsky where the work is reinterpreted from a designer perspective. This method is used to propose a method of extracting the iconographic and iconological elements of cultural demonstrations resulting in the innovation of the canton. Taking advantage of the values and cultural heritage of the nation and showcasing its aesthetics, a greater flow of visitors to the area is ensured as well as the dynamics of the local economy.
A Study on Cultural Sustainable Tourism in Context of Painted Scrolls
Authors: Singh Kanak Lata
Published: March 2019

India is known for its reach in Art and Culture. Cultural tourism provides a major contribution to the development of the country from different aspects. Apart from supporting the Indian economy, cultural tourism also helps in preserving and developing unique art traditions which are slowly dying out due to negligence. patachitra, the painted scroll of Bengal is one of them. The patachitra tradition is an essential part of intangible heritage based on tour practices. Patuas, as they are known as a community, chiefly represent a group of artists wandering with their painted scrolls and narrating the stories from place to place to earn their livelihood. The patachitra is a platform where several mediums of communication are united such as visual messages, oral traditions and music during process of storytelling. These painted scrolls represent narration of Hindu mythologies as well as folklore. In this regard, considering business as one of the purposes of tour, this research about patua artists working for patachitra in West Bengal is an attempt to reveal the fact that artifacts, as a part of culture, and tourism are two sides of the same coin. The existence of one is essential for the survival of the other.

Published: March 2019

With rapid climate changes in recent years, it has become important as it is necessary to think about a new concept of architecture that respects and considers the environment. To counter these changes, the concept of environmental and green architecture starters' theory has appeared as one of the applications of creative solutions in buildings. Architects then began turning it from a theoretical study on the method of the design of buildings and making them environment-friendly by reducing the consumption of resources to run the building and reduce damage to the environment due to Alanbosat and waste resulting from construction work. Environmental and green architecture does not just reduce the impact on the environment but also supports energy-efficient buildings, which achieves self- sufficiency within the building. It also provides energy production and exploits the optimal way efficiently and with equanimity. This paper aims to: - Highlight the importance of green architecture and sustainability in shape. - Reach a methodology to convert existing buildings into green buildings.

Video games can be considered a strong asset in the tourism industry. It is a form of media that allows for interactive experiences. It also allows the virtual reconstruction of historical sites and cities that are difficult or impossible to reconstruct physically, thus, introducing historical sites to a new generation. Pervasive gaming (playing on site) can help augment the tourist's experience by using 21st-century technologies, such as augmented reality, to reconstruct the site virtually and to let the player experience the history of the sites in a more engaging way. This paper aims to provide stakeholders (decision makers, preservation professionals, and game designers) with a guide on how to start the development process of a pervasive game in historical sites for the purpose of promoting the Egyptian architectural heritage to the next generation according to their understanding capacity and expectations. This paper presents pervasive gaming as a platform for the virtual restoration of historical monuments as well as the revival of the intangible aspects of these sites, particularly the historical stories associated with them.
Naturalism in Architecture Creating a Culture of Resilience
Authors: El Refeie Houssameldeen Bahgat
Published: March 2019

Naturalism is the philosophy that adopted the theory of evolution and the domination of natural properties. The popularity of naturalism was due to the rise of the extensive biological researches and the evolution of natural sciences by the end of the nineteenth century and the beginning of the twentieth. The emergence and the rise of these scientific theories were the contributing factors to the domination of naturalistic trends. It had an ample impact on urban and architectural schemes. Environmental catastrophes and the climate change that followed the second world war that reached its peak in the last two decades of the twentieth century were the major factors in attracting the attention to the importance of preserving nature. Naturalism was inspired by biological theories using a biological metaphor. The philosophy brought to mind techno-scientific images which drew out the concept of genetic architecture. These images tried to synchronize with the natural variables in order to achieve the concept of sustainable development. This paper aims to examine the concept of sustainable architecture by studying the architectural movements that are influenced by nature and biological theories, such as terms, models, projects, and buildings. For a deep understanding of the current discourse, this paper searches for the impact of the philosophy of naturalism on the history of sustainable architecture. The paper focuses on the notion of resilience while picturing the transformation of economic, political, social and physical structures into resilient urban spaces and organizational patterns which have the potential to grow and change—a subject mostly presented in a historical review.

Published: March 2019

The issue of examining the earthquake safety for existing constructions, which form the basis of urban mitigation strategies, requires new methods and tools according to each city’s and society's specific conditions. The common goal in all methods is to yield correct results in a timely manner. However, due to the multiplicity and complexity of the parameters used in the examination, auxiliary tools are needed. This is not only because of difficulties in collecting data, but also in order to obtain reliable results. Thus, collected data must be analyzed in computerized environment. In this study, an evaluation tool (software) called "Disaster Risk Analysis and Evaluation System (DRAES)" is developed. This software has been implemented and tested in Antalya; one of the metropolitan cities of Turkey within an area of 8800 hectares at 26610 buildings. The obtained results were evaluated comparatively which determined, consequently, the priority areas for planning as an important input for the city of Antalya. In this study, the general structure and working principle of the developed software are given. The source codes and data base of the program have been registered in accordance with the regulation on Registration of the Intellectual and Artistic Works of the Ministry of Culture and Tourism.
Toward Urban Spaces of Quality: Through the Existing Urban Legislations in Egypt
Authors: El Sharnouby Haitham
Published: March 2019

Egyptian urban spaces suffer from a chaos that is the result of crowded and disordered pedestrian sidewalks, streets and shop signage. This chaos creates a negative effect on, both, the image of the city and the quality of life within these urban spaces. Many legislations and regulations in Egypt attempted to deal with these issues. Similarly, the Egyptian government established many organizations and authorities in order to deal with these issues with little success. The National Organization of Urban Harmony (NOUH) is one of those organizations established by the government to take the responsibility of dealing with pedestrian sidewalk and shops’ signage while the municipality deals with road occupations. These organizations should perform their responsibilities through the Egyptian legislations. The research at hand aims to find a solution to that particular problem which has influenced the quality of the street and its reflection to the quality of life as result. In order to find a solution, the research attempts to find a mechanism to boost the role of shop signage as an element of urban spaces in order to emphasize street quality. Thus, the research well be divided into four parts: part one reviews the quality of urban spaces and the meaning of its terms while part two reviews the concept of the quality of life and the relation between the quality of life and urban spaces. Part three demonstrates the urban quality of life through tangible and intangible approaches. Finally, part four reviews the Egyptian legislations that deal with research issues and attempts to find the difficulties that faced when enforcing laws. Finally, the research conclusion illustrates the most important issues in the research and their proposed solutions.
Material’s Perception Strategy in Terms of Adaptive Re-use Within the Computational, and Parametricism Context
Authors: Mansour Sarah
Published: March 2019

Creativity has been assigned to the design or drawing, with materials most often being specified as a result of design rather than being considered a driver of it. Designers empowered by new technology now consider form as it is defined by identifiable systems. This evidence based, parametric methodology is a response to two decades of digitally-derived projects, often produced simply for their novelty. The best work results when the architect has combined respect for the old with a skilled progressive command of the new. Material culture is portrayed as the physical confirmation and articulation of a culture in its relics and design. In the time that we comprehend the thought of material culture not just as having importance for investigations of the past. yet in addition getting a projective limit. we may now be at a critical defining moment.. As computation starts to significantly change our origination of the material, so in architecture this will defy the set up connection between the procedures of design and the physical fabrication of the constructed medium . Obviously, computation was brought into design & architecture the greater part a century back. furthermore, expanding digitization has since plagued all parts of the field . As though, it has remained emphatically impacted by the theoretical isolation of the procedures of design and making that has overwhelmed structural plan thinking since the Renaissance, and it is just now that creators are starting to deal with the computational void as never again disconnecting from the physical domain.
The Correlation of Deconstruction Architecture to Arab Architectural Identity
Authors: Rabboh Emad H. , Elmansory Ali A.
Published: March 2019

The Arab architectural identity is characterized by the originality of the various Arab cultures. Islamic culture is what makes Arab societies unique and it is what inspired Arab architecture. Consequently, the Arab architecture encounters contemporary challenges. If modern architectural trends influenced Arab civilization, it could then obliterate its identity over the years. Moreover, positively interacting with modern architectural trends must take place rather than negative interactions. The aforementioned reasons leave this phenomenon the subject of discussion and research and thus the lack of update and development of the vocabulary of Arab architecture. The proposed study discusses the problem of the correlation of deconstructive architecture with the architectural and Arabic identity through the end of the 20th century until 2017. In order to arrive at the definition of the philosophy of deconstruction architecture and the appropriate relationship between it and the Arab architectural identity, the study utilizes a qualitative descriptive methodology that tries to give a generic image of philosophy and characteristics. Deconstruction architecture attempts to link the positive aspects of architecture and Arab identity through the analysis of the frameworks of this philosophy of particular architectural works of various architects who adopt this philosophy of architecture. Responding to the above, the current study shows that it is better to strip the modern trends and take what suits the Arab culture.

Published: March 2019

This paper investigates an experimental study on reducing stress acting on buried flexible pipes by using expanded polystyrene (EPS) geofoam techniques. An experimental model was carried out with dimensions depending on pipe diameter (D) and location, the used fill cover material was from sand and EPS blocks either embankment form, or within sand backfill as embedded layer. The pipe flexible is un-plasticized polyvinyl chloride (UPVC). A series of experiments have been carried out by using static surface loading on rectangular steel plate,where the load is distributed over the backfill. The behavior of sand backfill around the pipe was observed, and the displacement and strains of the pipe were measured. The experimental results showed that the embedded layer of EPS geofoam block embedded in sand for different techniques reduced the deformation of flexible buried pipe, with high efficiency and low coast compared with EPS geofoam only. The results reveal that, the most effective methods thatcanreduce the stress on buried flexible pipe with low cost were EPS encasement block with head void method, and EPS block embraces the upper part of pipe method.

Published: March 2019

Kuwait is facing a current construction boom with projects worth of more than USD188bn. The huge infrastructure spending plan of Kuwait is reflected with a growing demand of concrete as concrete is the most commonly used building material in the local construction. At the present, the quarrying of coarse aggregate which is a main concrete constituent material is banned in Kuwait since 1997 and construction industry depends on the imported coarse aggregates from neighbouring sources such as United Arab Emirates and Iran. Kuwait is also interested in challenging the growing concern of an effective environmental management of water, land and atmosphere to achieve a sustainable civilization. The increasingly environmental pressures coupled with the limited available economical resources are causing the decision making authorities to consider the practice of recycling and waste utilization. This paper presents Kuwait Institute for Scientific Research (KISR) efforts to investigate sustainable sources of coarse aggregate for construction industry from waste. The first sustainable source investigated is the production of synthetic lightweight aggregates utilizing combinations of argillaceous indigenous and waste materials, and the second is recycled aggregates from construction and demolition wastes. The potential of the two sustainable sources of construction aggregates are presented and the needed steps for real industrial application are addressed.

Published: March 2019

The present research presents an intelligent fuzzy logic controller (FLC) system for control water level of nonlinear systems, whereas the cross-section area of the vertical water is not constant (conical tank). The mathematical model of the conical tank level system was derived and its simulation runs were carried out by considering the FLC. For comparative analysis, a similar test runs were also carried out by means of conventional ZN based PI-mode. Interestingly, the results illustrate that applying the FLC system in the control loop in the conical tank system could provide a good tracking performance than that of conventional PI model.

Surface textured and DLC coated (hydrogenated amorphous carbon) samples were assessed for their coating performance at 40 oC, 80 oC and 125 oC. As a result, textured a-C:H DLC demonstrated higher but stable coefficient of friction (COF) at high temperatures as compared to un-textured DLC samples. However, textured DLC samples showed higher wear resistance compared to un-textured DLC coating. The enhancement can be elucidated by the lower graphitization of textured DLC samples.

Coal mining and washing activities in South Africa often lead to the generation of fine and ultra-fine coal which is in most cases discarded due to high handling and transportation costs. Studies conducted revealed that a large quantity of these fines have market acceptable calorific values and lower ash contents. In order to reduce fines discarded, processes have been developed to re-mine and process the fine coal discards with the aim of improving the calorific value, adding them to coarse washed coal to increase the yield as well as pelletizing the fines so as to meet the market specifications in terms of size. The goal of this study was to evaluate the efficiency of fine coal washing using gravity separation methods and comparing the products thereof to the market specifications with regards to the calorific value and the ash content. Coal fines from the No.4 lower seam of the Witbank coalfield in South Africa resulting from a dry coal sorting plant were subjected to a double-stage spiral test work, heavy liquid separation and reflux classifier test work respectively. The reflux classifier achieved products with low ash content and an increased calorific value, at high mass yields. At higher fluidization water flowrate, the reflux classifier performance was superior to that of the spirals with products of lower ash content and higher calorific value. At low cut point densities, heavy liquid separation yielded the cleanest products with very low ash content but at much lower mass yields. As the density increased, the mass yields increased with the ash content while the calorific value decreased. Most of the products from the different processes met most of the local industries’ specifications but none of them met the export market as well as the gold and uranium industry specifications due to the high ash content.

Published: March 2019

Exterior Thermal Mass (eTM) is known to improve building energy and thermal comfort performance. Despite its known benefits, studies to date have not thoroughly addressed the effects of eTM on building environmental performance by considering a wide range of influential factors and various climatic conditions. This paper addresses such a gap in the body of knowledge by conducting a comprehensive and detailed analysis of eTM impacts on residential buildings’ energy performance. Using quantitative research and simulation analyses, this study has found various trends of energy reductions and, in a few cases, energy increases depending upon the location of projects. In fact, the cooling energies are shown to increase of up to 4% for the scenario of 20 cm thickness wall in several locations. Aiming for better energy and design load scenarios, this research has also established the optimal eTM depth to help architects and engineers make informed design decisions with regard to building envelopes, which is particularly important for developing countries with similar climates studied in this paper, where the use of masonry materials is widely common. As for future steps, further exploration of cooling energy increase phenomenon, which was observed for several climates is recommended. Also, coupling eTM with code-required thermal insulation based upon specific climatic locations and evaluate their integrated performance can be considered.
