Sun provides 70 % of hot water in blocks of flats

Submitted by Baerbel Epp on December 13, 2017
Construtora AlttiMore than 3,500 solar water heating systems have been in operation at blocks of flats across Brazil’s ‘solar city’ Belo Horizonte. This figure, an estimate by organisations which were previously part of a business cluster called BH Solar, affirms the city’s exceptional status in Brazil and around the world. Most of the solar systems have been installed on the roofs of high-rise buildings intended for the middle class and the wealthy. The photo shows two such structures. One flat has 4 bedrooms and extends over an entire floor, measuring 280 m². To provide the security that owners were looking for, recreational facilities, such as a swimming pool and a tennis court, have been set up inside the walls put up around the complex.

Belo Horizonte – Brazil´s Solar Capital

Submitted by Baerbel Epp on October 25, 2017
Belo HorizonteBelo Horizonte, a municipality about 600 km north of Sao Paulo in the state of Minas Gerais, is also known as the solar capital of Brazil. Not only does it have a population of about 2.5 million, but solar water heater installations on many of its high-rise multifamily buildings. The photo shows one example, a block of flats for the wealthy middle class. The roof is completely covered in solar water heaters, which meet around half of the annual hot water requirements. This article will present the main drivers of an exciting market development in Latin America: a university research group specialised in solar heating and cooling, committed system planners, strong manufacturers and a pro-solar state utility.

Brazil: Residential Demand Drives Market

Submitted by Baerbel Epp on July 24, 2013

In 2012, the Brazilian market of glazed collector area increased by 21 % to 625,866 m², whereas the unglazed swimming pool market segment only grew by 3 % to 525,508 m². According to the market statistics of the Solar Heating Department, DASOL, of the Brazilian Association of Refrigeration, Air Conditioning, Ventilation and Heating, ABRAVA, it is still the residential sector which drives the market, representing 66% of the sales in 2012, while the segment of industry, business and services accounts for 17 % and the social housing programme makes up another 17% (see the attached market survey in Portuguese). The chart shows the strong market growth over the last five years, which almost doubled in newly installed collector area from 671,156 m² in 2008 to 1,151,300 m² last year.

“I appreciated the initiative of introducing a new standard”

Submitted by Baerbel Epp on March 11, 2013

Elizabeth Duarte Pereira can look back at 40 years of solar thermal research in Brazil. Today, she is Professor at the UNA University Centre in Belo Horizonte in the state of Minas Gerais and is about to help set up a new test facility in Brazil - the third in her research career. During her stay in Berlin for the international SMEThermal conference, solarthermalworld.org sat down with Pereira to talk about quality issues, standards and Brazil’s solar-supported social housing programme.
