Utilization of Wind Energy in Green Buildings
As known, buildings and structures are blamable for great consumption of electricity, water and material. Green and sustainable buildings aim to decrease the environmental impact of buildings and reducing the power consumption. One of the methods to achieve these goals is by using a wind-energy system. To design this system, big or small turbines (home-scale turbines) may be utilized. Using any type of these turbines depends on location, wind speed, and building structure. In this paper, a building model is introduced with a suitable system of wind turbines.
Wind Energy Potential on A Highrise Building: A Preliminary Study
Journal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2021
Indonesia has an abundant renewable energy source. One of them is wind energy resources. Unfortunately, Indonesia's wind energy resource is not fully utilized, especially for application in high-rise buildings. The paper investigates the potential of energy production from the horizontal-axis wind turbine (HAWT) and the vertical-axis wind turbine (VAWT) on the rooftop of a university building in Indonesia. The wind speed data were measured on the rooftop of the building for seven months. The data was analyzed using Weibull distribution. Based on the probability density function of the Weibull distribution, the potential energy production was calculated using the power curves from the manufacturer. Comparing energy production between HAWTs and VAWTs has shown that VAWTs can produce more energy than HAWTs. Using six turbines, VAWTs can produce 48,476 kWh. On the other hand, with four turbines, HAWTs can produce 41,729 kWh. The reason is that VAWT requires shorter distance requirem...

The increasing interest among architects and planners in designing environmentally friendly buildings has led to a desire to explore and integrate renewable sources of energy. Roof mounted wind turbines is a technology that presents a high potential for integration within the built environment. However, there is a state of uncertainty regarding the feasibility of these wind turbines. This paper argues that part of this uncertainty is attributed to uninformed decisions about positioning and locating urban wind turbines. This is underpinned by lack of consideration to the accelerating effect of different roof shapes, buildings' heights and surrounding urban configurations. This paper aims to present the results of Computational Fluid Dynamics (CFD) simulations for the purpose of identifying the effect of different roof shapes on the energy yield and positioning of roof mounted wind turbines covering different buildings' heights within different urban configurations under different wind directions. Results from this investigation suggest that an increase in energy yield could be achieved which can reach 56.1% more electricity in the case of a vaulted roof if an informed wind assessment above buildings' roofs is carried out.

Safety of the buildings around the garden is analyzed by comparing the change of the wind pressure coefficient.

Article On Roof Geometry for Urban Wind Energy Exploitation in High-Rise Buildings
2015
The European program HORIZON2020 aims to have 20% of electricity produced by renewable sources. The building sector represents 40% of the European Union energy consumption. Reducing energy consumption in buildings is therefore a priority for energy efficiency. The present investigation explores the most adequate roof shapes compatible with the placement of different types of small wind energy generators on high-rise buildings for urban wind energy exploitation. The wind flow around traditional state-of-the-art roof shapes is considered. In addition, the influence of the roof edge on the wind flow on high-rise buildings is analyzed. These geometries are investigated, both qualitatively and quantitatively, and the turbulence intensity threshold for horizontal axis wind turbines is considered. The most adequate shapes for wind energy exploitation are identified, studying vertical profiles of velocity, turbulent kinetic energy and turbulence intensity. Curved shapes are the most interesting building roof shapes from the wind energy exploitation point of view, leading to the highest speed-up and the lowest turbulence intensity.

Study on High-Rise Building Using Wind Energy at Humid Tropical Climate
Chemical Engineering Transactions, 2017
In Low Carbon City it is important to reduce the emission of greenhouse gases (GHG). It means buildings have to reduce the energy consumption of fossil fuel and take action to use clean energy such as wind energy. The higher altitude, the higher wind speed. Wind speed as a function of altitude has a chance to be used in high- rise buildings. Indonesia is a humid tropical country, which generally has the character of relatively low wind speeds. In another hand, high-rise buildings have considerable potential value to utilize height as a factor to obtain sufficient wind speed. This study aims to identify the potential for wind energy in high-rise buildings in humid tropical climate. Problems focused on the design arrangement of wind turbine type on the building and the potential energy can be harnessed. This research was conducted in suburban areas where the roughness level is lower than the city centre. This study focused on assessing the potential of the wind on tall buildings in a ...
WIND ANALYSIS OF SQUARE AND RECTANGULAR GEOMETRY MULTISTORIED BUILDING
Its today's trend that we are expanding vertically instead of horizontally and constructing tall structures, either due unavailability of land or due man's desire to achieve something which unachievable and challenge himself. However whatever be the case as when we increase the height of the structure wind load becomes one of the most predominating factor in the design of any high rise structure, hence it is very important that a structural engineer should understand how the structure will behave as the height increases.In this paper effect of wind on tall structure is studied and analyzed, two geometry, square and rectangular with same plan area were selected. Software models for these two geometries were made in STAAD with three different storeyheightsi.e 15 storey, 25 storey and 30 storey and models were analyzed for both along and across wind condition for various parametric values.
Small Vertical Axis Wind Turbines for Energy Efficiency of Buildings
Journal of Clean Energy Technologies, 2015
The integration of renewable resources in buildings is a fundamental aspect of the 21st-century architecture in order to achieve zero energy buildings (ZEB), reduce the consumption of fossil energy and cut carbon emissions in urban areas. Besides photovoltaic systems, nowadays Vertical Axis Wind Turbines, whose business is growing globally, are becoming particularly interesting because of the potential to produce energy and to be building integrated. These small wind generators (200 W-10kW) can be used as stand-alone systems or as grid connected systems, and both can be paired with other energy conversion systems, such as photovoltaics. With a height from 2 to 10 meters, small wind turbines can be placed on rooftops, on streets or in gardens, they have relatively little visual impact and are able to produce energy even from modest wind flows. In addition to that, small wind turbines may also be coupled to street lighting systems (smart lighting). The article presents an analysis of the different types of vertical wind turbines available on the market, including investigational products, and illustrates how it is possible to install them on buildings (Building Augmented Wind Turbines) and the benefits achieved in terms of energy production compared to photovoltaic systems.
