Blinds for a perfect energy balance
The world-renowned consultancy firm PwC will have a new office block in Milan from 2020 on Piazza Tre Torri. Designed by Studio Libeskind, the tower will house 3,000 staff across 28 floors. Drawing inspiration from a Renaissance dome, the building slopes upwards across a concave arch to a section called the Corona, reaching its highest point 175 m above the ground.
The office block is linked directly to the shopping mall below, filled with shops and restaurants looking out onto the third-largest park in Milan, and the new M5 subway line.
The building already has LEED Gold pre-certification on the strength of its cutting-edge façade systems, the water recovery and recycling system and the photovoltaic installation.
An important role in ensuring the building’s desired energy balance and the correct management of heat and light, in combination with the triple glazing units installed in the façade, is played by the shading solutions for interiors supplied by Pellini Tende e Sistemi. In total, nearly 3,000 motorized roller blinds (230 V), averaging 3.4 m high and controlled by an automation system, were required. These blinds are made with EnviroScreen Verosol, a flame retardant 100% metallized polyester material that is completely PVC free. This material not only ensures excellent energy performance, but also genuine environmental respect as it is 100% recyclable and Cradle2Cradle Bronze certified.
By reflecting the sun and regulating light levels, the blinds help to cut the need for electric power for air conditioning and, consequently, reduce carbon dioxide emissions, yet guaranteeing excellent view through.
Since the northern elevation has certain trapezoidal sections, it was necessary to use inclined, guided shading systems to compensate for the irregular geometries and slopes between one floor and the next. Pellini’s R&D department had to design specific parts for these blinds to allow them to move laterally and adapt to the unique shapes of each façade module.
Called the “Curve”, the PwC Tower is the third such office block in Milan’s CityLife Business & Shopping District, located between the Generali and Allianz office blocks, which also have thousands of venetian and roller blinds supplied by Pellini and are key parts of this Milanese skyline.
