Abstract
The effect of wind distribution on the architectural domain of the Bahrain Trade Centre was numerically analysed using Computational Fluid Dynamics (CFD). Using the numerical data, the power generation potential of the building integrated wind turbines was determined in response to the prevailing wind direction. Simulating a reference wind speed of 6 m/s, the findings from the study quantified an estimate power generation of 6.4 kW indicating a capacity factor of 2.9% for the computational model. At the windward side of the building, it was observed that the layers of turbulence intensified in inverse proportion to the height of the building with an average value of 0.45 J/kg. The air velocity was found to gradually increase in direct proportion to the elevation with the turbine located at higher altitude receiving maximum exposure to incoming wind. This study highlighted the potential of using advanced computational fluid dynamics in order to factor wind into the design of any architectural environment.
Highlights
Building energy is part of a complex system that includes transport and urban planning and has major social consequences as well as climate change impacts
The computational domain comprised of the building geometry, which was designed according to the actual specifications of the high-rise tower and the specific wind turbines
The feasibility of implementing building-integrated wind turbines was determined by investigating the effect of structural morphology on the extraction of prevailing inlet wind
Summary
Building energy is part of a complex system that includes transport and urban planning and has major social consequences as well as climate change impacts. Buildings worldwide account for a surprisingly high 40% of global energy consumption and the resulting carbon footprint, significantly exceeding those of all transportation combined. Energy consumption of the Gulf Cooperation Council (GCC) countries is driven largely by residential use, with almost 47% of the electricity being consumed by the residential sector. Large and attractive opportunities exist to reduce building’s energy use at lower costs and higher returns than other sectors. Substantial investments will be required to achieve this target These will require the combination of actions called for in this report, including building energy codes, investment subsidies, labelling and reporting mechanisms, increased and trained workforce capacity and evolving energyefficiency designs and technologies. To achieve an energy-efficient world, governments, businesses and individuals must transform the building sector through a multitude of actions, which include increasing energy awareness globally
