The country mainly relies on oil and gas for producing electricity. Abu Dhabi emirate consumed 62,979,070 Mega-Watt hour (MWh) of electricity in 2016 with only 30,867 MWh produced from renewable resources. The carbon footprint of electricity generated from fossil fuels was estimated to be almost 26.5 million tons of Co2 equivalent in 2014. Therefore, the need to expand the power generation from clean renewable resources is of high importance. This study measures the feasibility of utilizing PV panels on the roof top of a mixed-use building while connected to the power grid of Abu Dhabi emirate under the net metering scheme. The building electric energy consumption was studied using Carrier HAP software, then HOMER software was used to design and simulate the grid connected PV system. The results showed that a 25 kW PV panels and a 25 kW invertor with an initial cost of $ 41,250 (...

Consequently, many educational institutions are trying to implement 3D printing in their curriculum to make it more challenging and appealing. However, the process is quite challenging as it needs experience and professionalism to select and employ the best courses and practices for this matter. This work is directed into sharing the best procedures and practices for implementing 3D printing in mechanical engineering education at UAE University. The courses described in this paper include geometric modelling (MECH315), Fluid Mechanics Laboratory (MECH348) and Mechanics of Materials (MECH305). Using 3D printing in these courses motivated students to be more involved in their learning process and enhancing their hands-on experience in additive manufacturing technologies.

A case study of Dubai climate has been chosen to demonstrate the design procedure in detail. The fuzzy controller input variables involve the inside temperature of the mosque space, the temperature difference between inside and outside the space, the dew-point temperature, and the population percentage of the space, defined as the ratio between the number of occupants inside the building, and the total building occupancy. The output of the fuzzy model is the compressor speed, as a percentage of the maximum speed. The method of designing the membership functions and setting the fuzzy rules is shown for each input and output variable based on the current literature. Operation curves have been generated for three months: January, April, and August to represent the diverse climate conditions of Dubai city over the year. The proposed smart controller is expected to lower the ener...

The average resident of Abu Dhabi consumed about 629 L/day of water in 2015. Therefore, reducing water consumption from residential sector is greatly essential. However, it is more essential to identify the best policy to fit Abu Dhabi residents' behavior. This study compares between different environmental policies used worldwide to lower water consumption. The study is based on a survey directed to the residents of Abu Dhabi emirate. The survey is designed to show the major water consumption habits of Abu Dhabi residents, their reaction to fluctuations in water prices, their environmental awareness with respect to water consumption and finally, their “willing to pay” for water efficient fixtures and appliances. The results of this study came to support the expectation that one policy is not enough to make people save water. The majority of respondents (97%) agreed that water is precious and it should be conserved but th...
