Dannenge International provides AirFixture Underfloor Air Distribution System for Birmann 32
The built environment has a great role to play in the attainment of a healthier and more sustainable world. This is becoming even more clear due to COVID-19 pandemic. Harmonizing occupational health, energy efficiency and thermal comfort provides stronger and healthier organizations as well as better buildings.
An example of this approach, the Birmann 32 Building, in São Paulo, Brazil, opted for AirFixture’s VAV diffusers, a brand represented by Dannenge International, covering an area of 70,000 square meters, on the 28 floors of this building.
VAV floor diffusers (UFAD) intelligently control air delivery based on the temperature demand of the occupied space and provide excellent ventilation for greater occupant comfort and health. The B32 project, which includes a public terrace, cafeteria, corporate spaces, and a 500 occupants theater, received a LEED Platinum certification from Green Building Council Brazil.
According to Ricardo Cherem de Abreu, Technical Director of Dannenge International, the application of UFAD, by concept, allows energy savings, both by demanding low power for ventilation, and by working with higher supply air temperatures into the occupied space, which allows higher temperatures in the cold water and better yields in the water cooling system. It also provides a healthier environment, where aerosols and particulates are pushed out of the zone of occupation, at the same time allowing a more individualized thermal comfort control. However, for this potential to be realized, it is necessary to work with the right equipment.
“As always occurs when we work with UFAD, it was with great satisfaction that we took part in the Birmann 32 project. We have always had excellent results when applying AirFixture UFAD systems, a company that works exclusively with this concept, with hundreds of successfully working systems around the world. The B-32 is an example of a sustainable building, in which greatly influences the quality and flexibility that an underfloor air distribution system can offer. I’m sure this is the best option to get a really healthy work environment, especially if we associate UFAD with an active air purification system, such as the Photo Hydro Ionization technology by RGF Environmental, proven effective in reducing airborne transmission of diseases, by blocking its direct path, person to person”, comments Cherem.
According to Michael J. McQueeny, P.E. Leed AP, President and Managing Director of AirFixture, along with Rafael Birmann and Renato Silva, his company began working at Birmann 32 in 2013, when the project was in its initial planning phase.
“AirFixture manufactures air conditioning systems for class A commercial buildings throughout the world, and Birmann 32 wanted to have the best system to provide a noticeably better air circulation with greater comfort, so choose (UFAD) from initial design, since it had already specified the raised floor for maximum flexibility. This system has been the choice of several office towers and corporate campuses around the world. With a design by Raul Almeida of Teknica, thermostatically controlled VAV floor diffusers were installed. The project was successfully completed in 2020. Surprisingly, more projects than ever are considering UFAD systems, that supply fresh air directly into people’s breathing zone. These systems have been shown to provide cleaner air in office space with 75% less particles in the occupied zone. All this while offering great efficiency and greater comfort and productivity. Maybe, Birmann really knew what they were doing in 2013 when they planned this project. They were planning the future!”, celebrates Mr. McQueeney.
