Intricate urban geometries can generate complex wind patterns that are difficult to predict. Wind assessment tools are expensive in relation to the cost of a small wind turbine project. Additionally, wind resource maps are inappropriate for urban areas. For this reason, there is a strong demand by the wind industry sector for cheaper and accessible wind assessment tools for urban environments. Kliux Energies is a Spanish SME which specialises in the manufacturing and marketing of vertical-axis wind turbines. Its patented turbines require minimal maintenance, make virtually no noise, are bird friendly and have a visual impact which is aesthetically pleasing. For these reasons, these turbines are especially suitable for residential and urban environments: buildings, private homes, cottage accommodation, hotels, walkways, squares and parks.
