| Summary: | There is a trend towards urbanization and thus higher energy consumption in buildings, while decarburization and renewable energy sources (RESs) are becoming top priorities. Building-integrated wind turbines (BIWTs) represent a potential solution, especially in urban areas where space is limited. The aim of this article is to examine the technical, economic, and environmental aspects of the application of BIWTs based on the scientific literature, considering innovations and challenges related to their wider application. The analysis shows that BIWTs have a high capital cost (CapEx) and levelized cost of electricity (LCOE) due to the lower capacity factor, shorter lifetime, and high cost of building integration. However, the application of technologies such as computational fluid dynamics (CFD), additive manufacturing (3D printing), and artificial intelligence (AI) makes it possible to enhance the efficiency of turbines and reduce production and maintenance costs. Esthetically acceptable performance, noise reduction and possible integration with photovoltaic systems further enhance BIWT. In the short term, BIWT will remain a niche market, but policies and legislation mandating greater use of RES in buildings, as well as financial incentives, can significantly boost the growth of BIWT, which is particularly likely in coastal areas with favorable wind conditions. In the long term, BIWT has the potential to make an important contribution to sustainable urban development and the energy transition. |
