“…The predicted results showed that energy demand of NZEB (Eco house) is 34.37 %less than regular house mainly due to 69.5% less HVAC and 23.16% Non-HVAC load respectively. As can be seen, the energy demand of NZEB was lower than a regular house, which is consistent with the result obtained by The United Nation Environmental Program (UNEP) by using proven strategies and technologies in energy-efficient buildings is estimated to reach between 30% to 80% [26]. Building Energy Index is a measure of total energy usage of the house in one year divided by the total floor area of the house.…”

“…As predicted by the simulation tool, Building Energy Intensity (BEI) of Net Zero Energy Building (NZEB) at HCT was 87.20 kWh/m 2 /yr. which was 61.24 % less than the same size regular house in Muscat and 27.08 % less than the required value by the Passive House Institute (PHI) which is 120 kWh/m 2 /year [26].…”

The building sector is the largest consumer of the primary sources of energy worldwide. The most commonly used primary sources of energy to generate electricity are oil, coal, peat, shale, natural gas, nuclear, hydro, renewables, biofuels, and waste. The energy demand by the building sector is about 40% of the world's energy production.Net Zero Energy Buildings (NZEBs) is the best solution recommended by the energy experts to reduce substantial pressure on primary sources of energy contributed by the building sector. There is a marginal gap between estimates made during the design stage and actual energy performance of residential buildings, primarily due to a lack of understanding of the factors affecting energy use and whole building simulations software limitations. The purpose of this research work was to conduct a comparative analysis of a predicted versus actual energy consumption of prototype Net Zero Energy Building (NZEB) constructed at Higher College of Technology, Muscat. Hourly Analysis Program (HAP V4.2) was used to predict energy demand of NZEB at HCT and same size regular house in Muscat. PVWatts calculator was used to determining possible power generation by the PV system installed on the roof in the form of a canopy. The constructed house was tested for one month to perform multiple tasks as per competition requirements in which one of the major tasks was to produce onsite energy production by PV panel's equivalent to the energy consumed by the house. The actual energy consumption results were compared with the simulated result and observed that actual energy demand of house was approximately 20% lower than that predicted by the simulation tool. The comparison of simulation results between NZEB and regular house indicated 61.24 % less energy demand of NZEB, mainly due to less HVAC load. The simulation result for BEI of NZEB showed 87.20 kWh/m 2 /year as compare to 225.1 kWh/m 2 /year for same size regular house. The simulated result obtained from PVWatts calculator for competition period and actual production of an installed PV system at the top roof showed a minor deviation of 0.73% only. It is also observed from the results during the competition period house exported 1221 kWh energy to the grid.

“…Future buildings, embracing intelligent, smart, green and responsive attributes, have become a common topic of various academic debates, research investigations and practical implementations related to the architecture, engineering and construction industry. Besides, recent studies have focused on the sustainable dimension of buildings, their embodied intelligence, and responsive potentials as well as their contribution to smart cities (Ahvenniemi et al 2017;Alalouch, Saleh, and Al-Saadi 2016;Bibri and Krogstie 2016;Martos et al 2016;Yang, Xu, and Shi 2017).

Health and well-being are vitally important aspects of people centric building design and are the roots of productivity. Sick building syndrome (SBS) is a collection of factors that can negatively affect physical health in several ways. Besides physical health is also related to psychological well-being because the human body is one interactive biological system. This paper focuses on reviewing the current state of knowledge on building sickness syndrome which has been prevalent as a building illness since the 1970s especially in offices and schools. While the concepts of intelligent, smart and sustainable buildings have gained considerable attention during recent decades, there is now increasing attention being given to designing healthy buildings. This study provides a review about SBS symptoms. Several negative effects of SBS are identified and potential solutions are advocated. Finally, the study stresses the role of built environment and concludes that ongoing research towards tackling SBS and developing healthy indoor environments should not be limited to a single formula as any health-related building design approach is dependent on several interacting factors.

Prior to the discovery of electrical power, the buildings in the UAE were built with a concentration on the passive designs in order to have daylight and natural ventilation as well as avoiding the undesired heat. The wind tower was considered as the most familiar cooling strategy followed in the traditional architecture. However, the advanced air conditioning systems of the present time have removed the need for the wind catchers since the indoor comfort could not be achieved enough by the wind towers and at the same level that advanced air conditioning systems can do. Despite the integration of the Green Buildings in UAE, the cheap energy prices and the poor attention to energy efficiency buildings have converted UAE to one of the top ten countries worldwide that have high electricity consumption per capita. This work offers a low carbon proposal to solve the problem and demonstrates three strategies that can be adopted in UAE to implement energy efficient buildings without compromising on the indoor comfort and air quality. IES VE and RETScreen software were used to simulate and analyse the proposed strategies. Using proper wall construction material that has minimum thermal transmittance value is one of the strategies that can be implemented to reduce the airconditioning operating time thus less energy consumption. In addition to its benefits to the urban area, Green Roof is the second strategy that can be also implemented in order to reduce the thermal transmittance value of the roof. The last strategy is to employ Photovoltaic Panels to produce clean energy and to reduce the reliance on the fossil oil-generated power. As an overall, the bundle of three strategies has proved its efficiency to reduce the cooling energy consumption. The total electricity saving was 15.45 (MWh) and with a percentage of 19.6% of the total base case cooling power consumption.
