Beautify buildings and residences e, at the same time, to generate energy from solar source, providing an integrated aesthetic filling to buildings is the major objective of systems BIPV (Building Integrated Photovoltaics) – an application that is increasingly gaining ground in the Brazilian market.
Em webinar held by Canal Solar this Tuesday (30), Clarissa Zomer, founder of Architecting Solar Energy, highlighted the main business opportunities that exist for the sport in the country and guaranteed: Professionals who specialize in photovoltaic projects integrated into architecture come out ahead of the rest.
According to her, in a market So competitive like the solar, who offers projects that go beyond conventional rooftop installations and which contain a harmonious look expand your Portfolio and, consequently, if stand out more.
“Today, there are few professionals who have mastered photovoltaic integration in architecture, and it is a very large niche to be explored. Those who specialize will differentiate themselves, because they will have the best projects and the best cases”, says Clarissa.
According to her, nowadays the vast majority of photovoltaic projects are developed by integrators only when the architectural design of a house or commercial establishment is ready.
“We hear about cases, such as a 400 square meter house that has a roof so cut that it has practically no area for generating energy. This results in inefficient solutions that often have questionable aesthetics”, he highlighted.
After all, what are the advantages of BIPV?
Basically a BIPV system consists of photovoltaic modules of the most different colors and styles (not just blue and black) and which are integrated into construction as elements or materials that form part of the building structure.
Thus, replace an element of conventional construction, rather than linking to one. In addition to generating electricity, can also provide different functionalities additions to a building.
For example, they can provide protection against the sun's rays, thermal insulation, protection against rain, partial shading of areas, complete replacement of tiles, etc.
“When I see the placement of conventional modules on roofs, what I see is disintegration. I only see large rectangular solar modules, usually blue or black – which are not usual colors on roofs – fighting with the architecture of the building”, highlighted Clarissa.
Furthermore, the professional explains that, in the vast majority of cases, conventional systems are installed according to the customer's required power and not according to the existing form, which makes it impossible to achieve a more harmonious integration that covers, for example, the entire coverage. of a building.
Current cases
To better elucidate the functioning of photovoltaic systems integrated into architecture, Clarissa cited cases recently developed in Brazil and around the world during the webinar.
One of them, for example, involves the use of technology in headquarters of the Germinare Business of the J&F Institute, in São Paulo (SP).
The project developed by BIPV Solar Warranty for the education center included the installation of breezes photovoltaics using thin flexible films, which weigh just two kilos and are much lighter than glass modules.
“We designed this system to block undesirable radiation from the building, reducing the temperature in the classrooms while at the same time managing to generate energy from this undesirable radiation”, he explained.
However, according to her, there are many other examples in which photovoltaic modules can fulfill different architectural functions, such as roofs and coverings of the most different colors and shapes.
One of these examples is the installation of conventional modules on the curved roof of the UFSC photovoltaic laboratory (Federal University of Santa Catarina).
On site, the 1,60m x 1,00m modules were purposely placed in a landscape position, perfectly composing the curved roof, giving the impression that the modules are all curved, whereas, in fact, they are completely rigid.
Clarissa also brought international examples of BIPV system applications. One of them was the European Union headquarters building, in Brussels, Belgium.
The building is made up of the union of a historic building and a contemporary one, in which the connection between the two buildings is through walkways and the photovoltaic roof with semi-transparent modules.
“We have an old, historic and listed building here that has had an expansion. This expansion joined the old one through a photovoltaic covering made of semi-transparent modules.”
