Solar Architecture, BIPV, ConstructionAbstract
The article addresses the implementation of photovoltaic (PV) solar energy systems in buildings, focusing on Building C of the Laboratório Fotovoltaica/UFSC, located in Florianópolis/SC, as it highlights the promising scenario of solar energy in Brazil, with an installed capacity of 35 GWp, mainly in distributed generation. The text emphasizes the efficiency and cost reduction of PV systems, encouraged by regulations such as ANEEL REN 1000/2021 and Law No. 14300/2022. The article underscores the complexity of implementing Building-Integrated Photovoltaics (BIPV) compared to Building-Applied Photovoltaics (BAPV), especially in the Brazilian context, where the availability of BIPV products is still limited. Building C is presented as an innovative solar architecture project, overcoming challenges from the design phase to the construction phase and even maintenance. Specific challenges faced during the construction of Building C are discussed, in which the treatment of waterproofing and the adequacy of the PV modules' fixing structures on the building's roof required tailor-made solutions (rubber and polyurethane joints, structural reinforcements and manufacturing of modules and special water conductors) and generated delays during construction. The search for companies specialized in both construction and solar energy is essential to guide future projects and drive the evolution of solar energy application technology in buildings in the Brazilian market. In conclusion, the article highlights future concerns, such as extensive cleaning and maintenance of PV modules, and emphasizes the ongoing need for innovation to facilitate the successful integration of PV systems into buildings in the country. The work of the Laboratório Fotovoltaica/UFSC is presented as a catalyst for transforming the sector, encouraging a more comprehensive and efficient approach to implementing BIPV projects in Brazil.
