Heritage settlements have long histories that consist of multiple layers of urban layouts, building forms, and culture. Looking at the first layer that formed the initiation stage of the growth becomes a difficult task because of the disguise of other successive layers. This article studies the abandoned village of Tinbak in Qatar that exemplifies a settlement at its initial stage of development. The method of examining a societal normative image of culturally suitable domiciliary development adds to the understanding of a heritage settlement layout. However, the village lacks literature sources and urban and architectural documentation. So, this article presents the first documentation of the tangible characteristics of both urban morphology and architectural typology. Site visits, oral documentation, photographic records and a 3D Faro scanner with a 130 m range were utilized to record and document the physical environment.

The upper wing wall can be integrated into the windcatcher to prevent direct solar and rain penetration. The impact of this combination was not considered in previous studies. Moreover, analyzing adaptive thermal comfort is another gap that was not addressed by preceding windcatcher studies, particularly for the tropical climate. Therefore, the current research aims to evaluate a two-sided windcatcher incorporated with the upper wing wall from two views: indoor air quality (IAQ) and adaptive thermal comfort. A small-scale model was tested in the wind tunnel. Next, CFD models were validated against experimental data with a good agreement between the two methods. Windcatchers with different upper wing wall lengths ranging between 10cm to 50cm were assessed. The results showed that the length increase led to a slight increase in the ventilation rate, and the best performance was seen in the 50cm configuration. Subsequently, IAQ and adaptive thermal comfort were evaluated at different wind speeds of this climate. The results demonstrated that even in wind speeds below the annual average (2.5m/s), the windcatcher performance can still satisfy IAQ parameters such as airflow rate and air change rate, recommend by CIBSE Guide A. In addition, based on the simulated conditions the results showed that wind speed from 2.5m/s to 4m/s could provide thermal comfortwithin 50% to 80% of the ventilated space. Finally, the estimation of passive cooling power showed that windcatcher could provide a maximum (9.6kW) cooling power if the wind speed is at 4m/s and outdoor temperature at 23˚C.

The ruins of al-Zubarah hold within them valuable information for historians and anthropologists to know the society that once lived in it. Thanks to contemporary modelling methods, and a wealth of recent scholarship and documentation of the ancient city, we can virtually reconstruct its architecture. This paper shows the value of virtual reconstruction by building a model of al-Zubarah base primarily on Qatar Museums Authority (QMA) database and present the analytical and practical methods we adopt to do so. By reconstructing the city, we uncover its unique urban form, architectural language, and a glimpse of life once there. Because remaining ruins can only tell us so much about the city, we rely on a convergence of diverse sources from archaeological documentation to historical scholarship. The project has two stages: creating a volumetric model of the city and detailing four significant buildings, which are the mosque, palace, towers, and market.

The significant energy use and increasing requirement for good indoor environment quality in the built environment have led to a renewed interest in natural ventilation strategies such as windcatchers. Windcatcher is a roof-mounted device that supplies fresh airflow into a room and expels polluted air under the action of wind pressure and buoyancy forces. The aim of this review is to investigate factors which affect the natural ventilation performance of windcatcher including internal factors (related to geometry/design of windcatcher), external building features (microclimate) and surrounding environment (macroclimate) plus the impact of integration with other passive systems. From reviewing the literature, it was found that windcatcher with a square cross-section and curved roof demonstrates better ventilation in the room compared to other configurations. Moreover, the overall findings indicated that the integration of windcatcher with other natural ventilation systems such as solar chimney and wing wall has a considerable effect on the ventilation efficiency. In urban environments, buildings are often located quite close to each other, and the effect of surrounding structures on airflow profile cannot be ignored but only a limited number of works considered the impact of urban environment and objects (upstream or downstream) on the ventilation efficiency of windcatcher. Finally, the impact of vegetation, techno-economic cost and energy saving in a building are some significant gaps of current studies.

Successful implementation of the lean concept as a sustainable approach in the construction industry requires the identification of critical drivers in lean construction. Despite this significance, the number of in-depth studies toward understanding the considerable drivers of lean construction implementation is quite limited. There is also a shortage of methodologies for identifying key drivers. To address these challenges, this paper presents a list of all essential drivers within three aspects of sustainability (social, economic, and environmental) and proposes a novel methodology to rank the drivers and identify the key drivers for successful and sustainable lean construction implementation. In this regard, the entropy weighted Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) was employed in this research. Subsequently, an empirical study was conducted within the Malaysian construction industry to demonstrate the proposed method. Moreover, sensitivity analysis and comparison with the existing method were engaged to validate the stability and accuracy of the achieved results. The significant results obtained in this study are as follows: presenting, verifying and ranking of 63 important drivers; identifying 22 key drivers; proposing an MCDM model of key drivers. The outcomes show that the proposed method in this study is an effective and accurate tool that could help managers make better decisions.

Water scarcity is at the center of the world’s greatest challenges, including famine, disease, and sustainable development. In many countries, there are active researches aimed at improving the supply of fresh water through actions such as seawater desalination and water recycling. Researchers are also working, on a smaller scale, to harvest water from the atmosphere to serve individual households or small communities. Cool surface condensation, fog catchers, and humidity harvesting are three examples of sustainable approaches that relied on affordable and simple equipment. This paper aims to introduce the possibility of using water condensation to generate potable water by using a self-sustainable-energy device. The device is scalable; being able to meet the needs of a single household and up to a residential district. The focus of this research is on the function of a water-harvesting cube. It consists of a set of solar panels, an energy converter, a dehumidifier(s), a water treatment component, and a water storage tank. The sum of all parts forms a 1 × 1 × 1 m cube. The premise of the proposal is that one dehumidifier can produce a sufficient amount of pure water for an individual’s various daily uses. The researcher conducted two experiments during the summer of 2018, one in London, Ontario, Canada, and the other in Doha, Qatar. The result showed that in an environment of 50–70% relative humidity, a single dehumidifier could produce up to 15 L of pure water per day. The research here proves that the proposed water harvesting cube is efficient, affordable, and requires low maintenance.

Recent evidence suggests that many densely populated areas of the world will be uninhabitable in the coming century due to the depletion of resources, climate change, and increasing urbanization. This poses serious questions regarding the actions that require immediate attention, and opportunities to stave off massive losses of infrastructure, populations, and financial investments. The present study utilizes microclimate modeling to examine the role of landscape features as they affect ambient temperatures in one of the fastest growing regions of the world: Doha, Qatar. By modeling three study sites around Doha—one highly urbanized, one newly urbanizing, and one coastal low-density urbanized—the research indicates that at the neighborhood scale, the most effective scenario was that of adding mature trees along the sides of roads. In the coastal study area, the model results estimated a maximum hourly air temperature reduction of 1.35 °C, and in the highly urbanized inland site, surface temperature reductions were up to 15 °C at 12:00. While other scenarios were effective at reducing air and surface temperatures, the mean radiant temperature was also increased or nearly neutral for most of the other scenarios. This result highlights the need to develop improved shading measures for pedestrian pathways and outdoor recreational areas, especially for highly urbanized inland areas in Doha and cities with similar climatic conditions.

The green building rating systems endeavor to achieve the extent of sustainability in building scale; however, they are lacking in assessing the urban scale. Few green building rating systems have developed the neighborhood sustainability assessment (NSA) tools to this extent. Qatar has adopted some of these tools; while the local tool is needed that fits government sustainability policies and international agendas. Hence, this research developed the QSAS (Qatar Sustainability Assessment System) Neighbourhood Development (ND) assessment model. The main goal of QSAS-ND is to promote, enhance, and create a sustainable neighborhood in urban areas. To develop QSAS-ND, the researchers applied the Waterfall Process method, and accordingly, has conducted three phases; the requirement study, model design, and model validation. Phase one identified eight criteria for sustainable neighborhood assessment using Compression Matrix Development (CMD) method. Phase two designed the model and applied the Analytical Network Process (ANP) method to obtain the weights of criteria. The ANP analysis determined that compactness has received the highest limited value (LVC2=0.30730) among the criteria which is followed by urban connectivity (LVC1=0.29143). The model was implemented at Lusail city for validation. The implementation resulted that Lusail city achieved grade A (Superior), means that it has high performances in sustainable neighbourhood design, but needs minor improvements regarding diversity and transportation. Indeed, using the QSAS-ND model helps architects and urban planners to assess sustainability accreditation of urban and neighborhood areas in Qatar.

Climate change is receiving increasing attention in recent years. The transportation sector contributes substantially to increased fuel consumption, greenhouse gas (GHG) emissions, and poor air quality, which imposes a serious respiratory health hazard. Road transport has made a significant contribution to this effect. Consequently, many countries have attempted to mitigate climate change using various strategies. This study analysed and compared the number of policies and other approaches necessary to achieve reduced fuel consumption and carbon emission. Frequency aggregation indicates that the mitigation policies associated with driving behaviours adopted to curtail this consumption and decrease hazardous emissions, as well as a safety enhancement. Furthermore, car-sharing/carpooling was the least investigated approach to establish its influence on mitigation of climate change. Additionally, the influence of such driving behaviours as acceleration/deceleration and the compliance to speed limits on each approach was discussed. Other driving behaviours, such as gear shifting, compliance to traffic laws, choice of route, and idling and braking style, were also discussed. Likewise, the influence of aggression, anxiety, and motivation on driving behaviour of motorists was highlighted. The research determined that driving behaviours can lead to new adaptive driving behaviours and, thus, cause a significant decrease of vehicle fuel consumption and CO2 emissions.

Transportation is the major contributor of ever-increasing CO2 and Greenhouse Gas emissions in cities. The ever-increasing hazardous emissions of transportation and energy consumption have persuaded transportation and urban planners to motivate people to non-motorized mode of travel, especially walking. Currently, there are several urban walkability assessment models; however, coping with a limited range of walkability assessment variables make these models not fully able to promote inclusive walkable urban neighborhoods. In this regard, this study develops the path walkability assessment (PWA) index model which evaluates and analyzes path walkability in association with the pedestrian’s decision-tree-making (DTM). The model converts the pedestrian’s DTM qualitative data to quantifiable values. This model involves ninety-two (92) physical and environmental walkability assessment variables clustered into three layers of DTM (Layer 1: features; Layer 2: Criteria; and Layer 3: Sub-Criteria), and scoped to shopping and retail type of walking. The PWA model as a global decision support tool can be applied in any neighborhood in the world, and this study implements it at Taman Universiti neighborhood in Skudai, Malaysia. The PWA model has established the walkability score index which determines the grading rate of walkability accomplishment for each walkability variable of the under-survey neighborhood. Using the PWA grading index enables urban designers to manage properly the financial resource allocation for inspiring walkability in the targeted neighborhood.

Doha, Qatar is one of the arid coastal cities of the Gulf Cooperation Council (GCC) countries. Like similar cities, temperatures can vary widely throughout, with rapid and extensive development that has contributed to micro-climate changes. While numerous studies since the 1950s have assessed urban micro-climates, few have offered insights into urban corridor environments. This research is one of few projects to examine temperature records along two major roadways and identify factors that explain variation. The research uses vehicle-based air temperature traverses during late spring and summer 2016 using a Type T fine gauge thermocouple mounted in a white plastic tube and supported above the vehicle on the passenger-side window. The data were assessed in terms of four factors that may impact temperature along the corridors, including: distance from the coast, traffic volume, vegetation density, and building volume density from 50 m up to 400 m (in 50 m intervals) from the centerline of the traverse. Results indicated that the two most critical variables that predict air temperature patterns along the corridors are the distance to the coast and the traffic volume. This knowledge can be incorporated into urban planning and design practice for extreme arid environments to maintain temperatures that reduce heat-related stress.

Oil and gas construction projects are complex and risky because of their dynamic environment. Furthermore, rising global energy demand has increased the need for trustworthy risk assessment models for such projects that can provide adequate and precise policy planning. Traditional risk assessments in oil and gas construction projects do not consider the interrelationships of factors in the best-fit models. The Decision Making Trial and Evaluation Laboratory (DEMATEL) and Analytic Network Processes (ANP), called the DEMATEL-ANP approach, have been applied to other research disciplines to address this shortcoming. This method is able to construct a structural relationship among the different influence factors to visualize complex correlations. Thus, the purpose of this study is to showcase the DEMTAL-ANP risk assessment model to assess the overall risk factors of OGC projects. This study thus identifies the crucial risk criteria of such projects. Data were collected in 2016 through interviews with experts active in OGC projects in Iran. DEMATEL in this situation is used to determine the interdependencies’ relative strengths among the risks. The ANP method is applied to assess the relative importance of the risk factors and to determine the best strategy for implementation of a risk management program. The results presented in this study are a novel adaptation of the risk assessment methodology to OGC projects that determines the important risk factors that directly affect the project success, which in turn helps in formulation of policies for ensuring reliable energy supply planning.

Recent evidence suggests that urban forms and materials can help to mediate temporal variation of microclimates and that landscape modifications can potentially reduce temperatures and increase accessibility to outdoor environments. To understand the relationship between urban form and temperature moderation, we examined the spatial and temporal variation of air temperature throughout one desert city—Doha, Qatar—by conducting vehicle traverses using highly resolved temperature and GPS data logs to determine spatial differences in summertime air temperatures. To help explain near-surface air temperatures using land cover variables, we employed three statistical approaches: Ordinary Least Squares (OLS), Regression Tree Analysis (RTA), and Random Forest (RF). We validated the predictions of the statistical models by computing the Root Mean Square Error (RMSE) and discovered that temporal variations in urban heat are mediated by different factors throughout the day. The average RMSE for OLS, RTA and RF is 1.25, 0.96, and 0.65 (in Celsius), respectively, suggesting that the RF is the best model for predicting near-surface air temperatures at this study site. We conclude by recommending the features of the landscape that have the greatest potential for reducing extreme heat in arid climates.

Efficient and accurate methods and models are ever-demanding to determining the user satisfaction in energy efficient buildings. Thus, several techniques are developed based on sustainable building assessment tools and standards to achieve such target. However, the user satisfaction from adaptive behavior in the design phase of buildings lifecycle is never addressed. This paper attempts to identify the most applicable data input method to measure the satisfaction from adaptive behavior with energy efficient buildings in their design phase. A comprehensive literature survey on all user satisfaction data input methods is conducted to serve the taxonomy by classifying them into two major clusters depending on performance and perception. Kano method to measure satisfaction perception from cognitive experience is demonstrated to be the most suitable user satisfaction data input method. Furthermore, Kano method can delicately assist energy efficient building design consultants to assess the user contentment requirements for sustainable building accreditation effectively.

The study commences with a comparative analysis between desert adapted cactus plants and traditional mud houses. Primary comparative results yielded three main similarities: 1) Effective utilization of self-shading surfaces; 2) Plant spikes that resemble the wooden poles projected around wind towers and building openings in mud structures; 3) Implementation of thick walls/plant body forms with high R-values. The ribbed facade and wooden poles will go through aerodynamic experiments to illustrate their roles as essential passive energy elements in traditional houses. Experiments on traditional mud houses has been previously carried out by many researchers while assuming the wind is facing the buildings; what is significant about this proposal is that wind directions will be tested with different angles (0 to 90 degrees) to find appropriate situations where wind generates enough turbulence that help directing the wind inside the building openings. The study requires two models for experimentation, one model related to the wooden pole, and the other focused on the ribbed elevation. Tests will then be carried out using wind tunnel equipment. The QU Aspire wind tunnel has a working section of 2.5 X 2.5 X 2.5 m and can simulate wind of up to 25 m/sec at the working section. Moreover, Computational Fluid Dynamics (CFD) software will be used to minimize the wind tunnel utilization time.

Enhancing the quality of urban life is considered by social scientists. It has instigated a growing attention in findings from surveys aiming to measure the inhabitant image in particular places. This paper investigates preference and satisfaction that utilizes a model from both a conceptual and empirical perspective. It mainly explores the image of certain social-spatial factors enhanced in the degree of preference and satisfaction with neighborhood and housing types on both scales, as an overall and as details of urban elements and house features. It first presents a brief overview of literature and the methodology and then reviews findings covering 162 respondents living in two cities that represent four different neighborhood patterns, social-spatial characters, and housing types. The four neighborhoods are: traditional settlements, attached houses, tower apartments and single family houses. The major findings reveal that satisfaction within a given neighborhood does not necessarily associate with place attachment and similarly, despite realization of lacking certain social-spatial qualities in the neighborhood, people may feel attached to the place because of certain attributes. However, there is on one hand a positive relationship between satisfaction and feelings of a neighborhood as home, and on the other hand, differences in preference and satisfaction of house types, urban elements and house features.
