This paper looks into developing energy policy in the UAE in order to prompt renewable energy practices and thus sustainability in the UAE. This includes analyzing current and proposed future energy policies in the UAE. The research analyzed a wide range of strategies used in different countries in order to assess the best practice examples, while remaining mindful of the particularities of each country. Based on these lessons a strategy for promoting renewable energy in the UAE was formulated. The proposed strategy is composed of short, medium and long term policies. The proposed strategy was submitted to and discussed with relevant authorities and stakeholders in the UAE. Based on the feedback from the stakeholders the proposed policy was further refined. The main components of the final strategy include deregulation at three different levels (emirate, country and the gulf region), open access to the grid as well as financial incentives, e.g. implementation of a Feed-in Tariff. The final strategy is included at the end of the paper. © 2013 Elsevier Ltd.

The literature on Project Management (PM) shows that, in spite of advancement in PM processes, tools and systems, project success has not significantly improved. This problem raises questions about the value and effectiveness of PM and PM systems. This paper reports a research study which tests the relationship between PM performance and project success drawing from empirical data on PM professionals working in UAE project-based organisations.Multi-dimensional frameworks are validated and used in this study to measure PM performance and project success. A total of 154 completed questionnaires were analysed. Bi-variate correlation and multiple regression tests found a positive influence of PM performance and its contributing variables on project success. Additionally, new variable relationships that have not previously been identified are explored between individual variables of PM performance and project success. © 2013 Elsevier Ltd and IPMA.

The urbanisation of deserts in Dubai is one way in which this city can expand and explore its full potential. In this piece of research, a case study of the Dubai International Academic City was used as a basis from which to study the importance of planning and orientation of projects in open, unpopulated land. It demonstrates the various alternatives for project orientation relative to the sun and wind, its effects on temperature and wind readings and consequently on outdoor thermal comfort levels. ENVI-met was used to simulate various scenarios generated from the existing base case in both summer and winter. The orientation which best promoted and allowed for higher wind flow through the project was found to record the best outdoor predicted mean vote levels, approaching a neutral state. The findings of this research may be used for setting up regulations regarding the planning of desert areas in Dubai on the basis of early assessment of designs. © 2014 Elsevier GmbH.

This study is an evaluation of the environmental impacts of courtyard integration in midrise housing in the hot-arid climate of Dubai, The United Arab Emirates. Computer simulation is utilized to determine the overall energy consumption, energy savings potential and available daylight levels. The study is carried out in three steps. First, a comparison between conventional and courtyard buildings is conducted. Second, the effects of number of floors, type of glazing, wall thickness and insulation type & thickness on the performance of a courtyard type building are simulated. Lastly, an optimized courtyard model encompassing the best of each of the parameters studied in the second step is generated and tested. Converting a six-floor building from the conventional form to a courtyard form, keeping all building materials and parameters the same, resulted in a 6.9% reduction in the year-round total energy consumption. The optimized courtyard model, including variations on building materials, resulted in 11.16% reduction in the overall year-round energy consumption when compared to the reference conventional form building. Comparison between the daylight performance of the two forms showed that the courtyard form was better than the conventional form during both winter and summer test days with daylight factor values close to those recommended by the USGBC, which means that the courtyard form provides more usable daylight without excessive glare. © 2012 Elsevier Ltd.

The change in climate has led to an interest in how this will affect the energy consumption in buildings. Most of the work in the literature relates to offices and homes. However, this paper investigates a supermarket in northern England by means of a multiple regression analysis based on gas and electricity data for 2012.The equations obtained in this analysis use the humidity ratio derived from the dry-bulb temperature and the relative humidity in conjunction with the actual dry-bulb temperature. These equations are used to estimate the consumption for the base year period (1961-1990) and for the predicted climate period 2030-2059.The findings indicate that electricity use will increase by 2.1% whereas gas consumption will drop by about 13% for the central future estimate. The research further suggests that the year 2012 is comparable in temperature to the future climate, but the relative humidity is lower. Further research should include adaptation/mitigation measures and an evaluation of their usefulness. © 2014 Elsevier Ltd.

This piece of research is an analysis of the refurbishment of a hospital building in Abu Dhabi, United Arab Emirates, focusing on building envelope renovation. It considers a portion of a building and August, the month with the most cooling demand, for the study. The selected zone was on the fourth floor and has the advantage of a north and south axis with a roof and a reasonable amount of glazing on both the north and south sections. A detailed analysis of annual energy performance for the case study was performed through the use of a computerised simulation to explore energy performance shortcomings and it was defined as the ‘base case’. The energy consumption of the base case was then compared with that resulting from a new proposed building skin. New strategies included sunshade, exterior wall retrofitting, cool roof, new glazing and green roofs. These strategies were obtained from ASHRAE guidelines for hospital buildings, and the new results were defined as the ‘efficient case’. Future recommendations were drawn including the suggestion that a green roof is the most suitable strategy as it can achieve a significant reduction in energy consumption. This was highlighted by external conduction gain, which changed from 29 kW in the base case to 21 kW with a green roof. The results will inform both architects and designers of the savings potential from a variety of strategies. © 2016 Elsevier Ltd

The annual CO 2 emissions have more than doubled in the UAE since 1990. Electricity generated by fossil fuels is responsible for almost half of the country's emissions. Keeping with the Kyoto Protocol, the UAE decided to integrate nuclear energy into the electricity scheme to mitigate CO 2 emissions as declared by the government (Embassy-of-UAE, 2009; ENEC, 2010b). This paper evaluates the effectiveness of the UAE's proposed nuclear energy strategy in mitigating CO 2 emissions from the built environment up to year 2050. The IAEA's simulation model "MESSAGE" is used to estimate the energy demand and CO 2 emissions in the UAE up to year 2050.Several energy supply/fuels scenarios are modeled and simulated including the following: Business as Usual (BaU), the UAE proposed nuclear strategy (APR1400) as well as 12 more aggressive Clean Energy Era (CEE) proposed scenarios. Nuclear energy, especially in its extreme CEE scenario (8NPPs), was found to be more practical option in mitigating CO 2 than renewable energy and carbon capture and sequestration among the simulated scenarios. Nuclear energy also demonstrated an economic viability. The cost of electricity produced from nuclear energy was calculated to be 3.2cents/kWh, significantly less than the current cost of 8.15cents/kWh for electricity generation from fossil fuels in the UAE. © 2011 Elsevier Ltd.

Urban heat islands are phenomena that occur coupled with rapid urban developments. The study was carried out to show the effect of organic and structured urban configurations on temperature variations throughout the year, especially in summer. The study investigated a larger area of the city rather than merely building-to-building relationships. It went beyond the confinement of street and building geometries and investigated how a number of these geometries put together in one context contributed to temperature variations. Computer simulation software was used to simulate three different urban configurations, representing an organic configuration in the Bastakiyah model and two structured configurations represented in the Orthogonal and Volume Ortho configurations. The simulations were carried out in Dubai, UAE for summer, winter, and autumn with fixed initial input temperature value of 32 °C and varying initial wind speeds (0.1 m/s and 3.6 m/s; and 7 m/s for summer case only).Assessment of the results showed that the organic configuration recorded lower temperatures in summer than both the structured configurations. The Orthogonal structured configuration did not behave as an intermediate configuration between the organic and highly structured grid configurations. The Volume Ortho configuration, though recorded the highest wind speeds, did not result in lower temperature values. It was shown that different configurations manipulated the behavior of the wind within the configuration. The sky-view factor and standard deviation were plausible explanations in the absence of obvious trends in some cases, and showed how urban configurations impacted temperature variations. It was concluded that, given this specific site location and the alignment of prevailing winds parallel to the roads, the organic configuration showed the better thermal performance amongst the three configurations. © 2012 Elsevier Ltd.

The influence of National Culture (NC) on Project Management (PM) and specifically project planning is not well understood. We report the results of an empirical study of British and Arab project managers in the United Arab Emirates (UAE). A structured survey method was used to investigate NC and the integrity of Planning processes. Differences between the Arab and British attitudes and perceptions of planning were analysed using Mann-Whitney U tests and Independent t-tests. Ratings in Scope, Time planning, Innovation/Technology, Integration, and Communication variables significantly differed between both groups, with the Arab group rating Communication higher and the British group rating the remaining variables higher. Hypothesised relationships on NC differences were supported for Scope, Time planning, Integration and Innovation/Technology. Since they rated the integrity of planning practices differently we conclude that NC influences the way a project manager understands the planning stage of the project. © 2012 Association for Project Management and the International Project Management Association and Elsevier Ltd.

This research is aimed at exploring the influence of external dynamic louvers on the energy consumption of an office building located in Abu Dhabi-UAE. The IES-VR software was used to predict the energy consumption of a representative office module in order to evaluate the overall energy performance of employing external louvers on the south, east and west oriented faades. The use of dynamic faades was compared to another simpler method of using light-sensor controlled light dimmers. The results show that the potential energy savings using light dimming strategy only was 24.4%, 24.45% and 25.19% for the south, east and west oriented faades, respectively. The proposed dynamic louvers system with light dimming strategy achieved energy savings of 34.02%, 28.57% and 30.31% for the south, east and west orientations, respectively. Detailed analysis of the results showed that the faade's optimal static angle was -20° for the south oriented faade and 20° for the east and west oriented faades. Using these fixed optimal angles resulted in slightly lower energy savings than that of the dynamic faades. This would seem to be a good tradeoff between savings in energy running cost and the investment required to install, operate and maintain a dynamic faades system. © 2010 Elsevier B.V.
