With urban growth, electricity and heat production may not be enough to meet new demands. The urban form can promote possibilities of alternative energy generation in the cities. This work verifies the potential of wind energy use in cities from a simplified methodology that involves qualitative analyses of the urban form and quantitative meteorological data for Goiania. The method is characterized by the following steps: a) Selection of the study area; b) Development of a thematic map where each zone is established from the similarity patterns of the topography, height of the buildings, presence of vegetation, type of use and occupation; c) Analysis of the wind energy potential for each zone, according to NBR 6123; d) Development of urban design guidelines that promote the installation of wind turbines in buildings in some areas of the city. Nine zones were identified, within which those with high occupancy density presented the great potential for wind energy during August to October, which are the months with higher energy demand for acclimatization of indoor environments. It suggests that the implementation of buildings with more than 40 floors in areas with low density can improve the capacity of micro generation of wind power in cities.

Com o crescimento das cidades, produção de eletricidade e calor podem não ser suficientes para atender às novas demandas. A forma urbana pode promover possibilidades de geração de energias alternativas nas cidades. Este trabalho verifica o potencial do uso de energia eólica em centros urbanos a partir de um método simplificado que envolve análises qualitativas da forma urbana e quantitativas de dados meteorológicos para Goiânia. O método é caracterizado pelas seguintes etapas: a) Seleção da área de estudo; b) Desenvolvimento de um mapa temático onde cada zona se estabelece a partir de padrões de semelhança da topografia, altura das edificações, presença de vegetação, tipo de uso e ocupação; c) Análise do potencial de energia eólica para cada zona, segundo a NBR 6123; d) Desenvolvimento de diretrizes de desenho urbano que promovam a instalação de turbinas eólicas em edifícios de algumas zonas da cidade. Foram identificadas nove zonas com formas urbanas distintas, sendo que aquelas com alta densidade de ocupação apresentaram maior potencial para geração de energia eólica durante os meses de agosto a outubro - meses com maior demanda de energia para aclimatação de ambientes internos, o que sugere que a implantação de edifícios com mais de 40 pavimentos em áreas com baixa densidade pode melhorar a capacidade de micro geração de energia eólica nas cidades. Diretrizes de planejamento que visam a eficiência energética e, principalmente, sustentabilidade urbana, dependem da avaliação de múltiplos critérios.
