“…BIWT needs an aerodynamic building shape to accelerate wind energy when it blows from certain directions. It is described if the building is appropriately designed, integrating the turbine can give some values (Bobrova, 2015). The first value is it can accelerate winds (power enhancement) from winds +/-75° from the direction of the prevailing wind (if the axis of the turbine is orientated with the prevailing wind).…”

The research aimed to comprehensively review the systems related to Building Integrated Photovoltaic (BIPV) and Building Integrated Wind Turbine (BIWT). The review purposed to observe the advantages and disadvantages of the application. Designers could use that comparison for consideration of choosing the most suitable Building Integrated Renewable Energy (BIRE) concept for projects. The research presented a literature review of BIRE systems, particularly on BIPV and BIWT systems. The critical analysis focused on some parameters related to their main energy source, type, influencing factor, efficiency, and boundary. The observation about BIPV would be divided into subgroups according to photovoltaic (PV) materials, modules, efficiency, performance’s boundaries, and the general rule of thumb of its installation. The research finds that the BIPV application has advantages in terms of the building’s application scale. It can be applied from small-scale to large-scale. Furthermore, the BIPV application does not need extra space and could directly replace the conventional building envelope materials. The issues of non-uniformity and heat transfer in BIPV can be solved by installing PV in folding-concept and placed an air gap with fins inside. On the other hand, BIWT also has an abundant energy source, but the application limits to windy areas (rural areas or urban areas in high elevation). Aside from those limitations, the BIWT application also has issues of structure, noise, and aesthetical value.

“…A utilização de sistemas de produção de energia a partir de placas fotovoltaicas (KHALID et al, 2016;OURIA, 2019;SADATI;EDWARDS, 2019) e sistemas de turbinas eólicas (KHALID et al, 2016;KRISTIANSEN;MA;WANG, 2019;SHABGARD;SONG;ZHU, 2018;WANG et al, 2017) podem diversificar a matriz energética e reduzir a dependência de energia de fonte hídrica e ou térmica, mitigando os custos com energia elétrica (BELUSSI et al, 2019;SEYAM, 2019). No entanto a utilização de energia solar e eólica ainda é mínima, devido aos altos custos de instalação e a demora quanto ao retorno de investimento (BOBROVA, 2015;MADESSA, 2015;MONTAGNINO, 2017;VIEIRA;MOURA;DE ALMEIDA, 2017).…”

“…Para a utilização destes sistemas também é necessário a ampla análise dos locais onde serão introduzidas, pois para maior efetividade do seu potencial de produção de energia solar, é preciso que haja maior incidência solar (SHUKLA; SUDHAKAR; BAREDAR, 2016; VIEIRA; MOURA; DE ALMEIDA, 2017). Enquanto que para a produção de energia elétrica a partir do vento, necessita que estes sejam constantes para que haja produção de 100% da capacidade instalada (BOBROVA, 2015;MONTAGNINO, 2017;WANG et al, 2017).…”

A construção de cidades causa impactos negativos ao meio ambiente, porém elas são fundamentais para a sociedade contemporânea, sendo crescente o interesse por ambientes urbanos. Este artigo trata-se de uma análise documental sobre os aspectos de consumo de água e energia elétrica do município de Governador Celso Ramos (SC), Brasil, no período de 2008 à 2017. Os resultados demonstram aumento de consumo de energia elétrica nos anos período em 69,16% para o setor residencial, 99,55% para o setor comercial e 1,68 vezes a mais para o setor industrial e o consumo de água aumentou 17,02% no mesmo período, com influência da sazonalidade. Mitigações como instalação de fontes alternativas de energia, como solar e eólica, e reaproveitamento de água da chuva e de águas cinzas podem ajudar a atender a demanda da população. Ressaltando que ações educativas devem ser adotadas pois a demanda per capita de água e energia elétrica aumentou no período de estudo. Como conclusão evidencia-se a necessidade de ações conjuntas entre prefeitura municipal, iniciativa privada, órgãos governamentais e munícipes a fim de minimizar os impactos que o crescente número de construções no município está proporcionando ao meio ambiente local.

“…Accordingly, some researchers proposed other locations to take advantage of the wind resource such as roadsides of highways [17,18] or specific spots in urban environments where the wind velocity increases [19][20][21]. In this case, the acceleration of the airflow is caused by the presence of buildings, which narrows the streamlines while flowing between them [22]. The acceleration of the airflow is also due to the thermal gradients existing in the city environment.…”

Background: This patent is based on the wind industry technology called Diffuser Augmented Wind Turbines (DAWTs). This technology consists of a horizontal axis wind turbine, which is housed inside a duct with diverging section in the direction of the free air stream. In this paper, a review of preceding patents related to this technology is carried out. Objective: This paper presents an innovative patent to improve the performance of horizontal axis wind turbines. In particular, this system is aimed at improving the performance of those turbines that otherwise might not be installed due to the low wind resource existing at certain locations. Methods: The most innovative elements of this patent are: (1) the semi-spherical grooves, which are mechanized on the surface of the two diffusers in order to guarantee a more energetic boundary layer; (2) the coaxial diffuser, which is located downwind following the first diffuser in order to increase the suction effect on the air mass close to the inlet; (3) the coaxial rings located around the first diffuser outlet, which are used to deflect the external airflow toward the turbine wake; and (4), the selforientating system to orientate the system by the prevailing wind direction. Results: An application of the patent for increasing the power generated by a horizontal axis wind turbine with three blades is presented. The patent is designed and its performance is evaluated by using a Computational Fluid Dynamics code. The numerical results show that this system rises the airflow going through the rotor of the turbine. Conclusion: The patented device is an original contribution aimed at enabling a more profitable installation of wind turbines in places where the wind resource is insufficient because of the wind shear caused both by the proximity of the earth and the obstacles on the earth surface.
