Greeen! Architects have been awarded an honorable mention for their Eco Towers, an office building in Hamburg, Germany for the Building and Environment Authorities. The office will accommodate 1400 people and will include several public areas as well as green gardens to “give room to nature and a create a green ambiance to all workers and visitors.”

More about the Eco Towers after the break.

As a highway and a frequently traveled road run along the southern edge of the project, the building’s façade prevents the impact of noise and heat against the east and south directions, while the panels also provide natural ventilation, views and sun protection. On the other side of the site, the façade is very transparent and open to provide “a nice, quiet and light urban space for the public.”

While the upper levels of the building are reserved for office uses, the lower floors, especially the exhibition spaces and the restaurant, allow the neighborhood to have access to the building. “The accessibility to the building for the public and the creation of informal and communicative meeting points are the leitmotiv of this design,” explained the architects.

Through extreme low primary energy needs (72% below EnEV 2007) the building obtains an excellent carbon footprint of only 18,9 kg CO2/m²a meaning a savings of more than 1.700 tons of CO2 per year. The building aims to receive the Gold certificate from the German Sustainable Building Council (DGNB) which analyses the project through three key sustainability aspects: Life-cycle cost analysis, ecology and social-cultural analysis and thermal, acoustical and visual comfort analysis.
