Design that really wants to deal with energy saving, living comfort and sustainability must be attentive to local conditions, able to make the most of the resources that the surrounding environment offers, based on a bioclimatic approach that mixes climatic-environmental, typological and technical-constructive levels: orientation and shape of the building, characteristics of the envelope are the elements to focus on.
A showcase project
Drees&Sommer, a consultancy company specialising in Project Management and Real Estate Consulting, proves that this is possible with the new building net plus energy in Obere Waldplätze 12 - OWP12, opened at the company campus in Stuttgart's Vaihingen district. A showcase project, a model of climate-friendly design: around 22 million euro invested, for digitally designed architecture with green credentials. After two years of work, keeping to time and budget targets, the building accommodates about 200 employees. 20 metres high and 70 metres long, it has a gross floor area of about 7,000 square metres, a large conference area, a terrace, a cafeteria and a restaurant.
Renewable energy, thermal insulation, recyclable materials
The new offices provide a response to the climate crisis and represent a shift to renewable energy sources in the building sector, designed to be as recyclable as possible, generating more energy than they consume. This is achieved thanks to the newly designed façade with high thermal insulation, photovoltaic systems on the roof and southern façade, the use of geothermal energy through wells and the greening of the northern façade.
The Vertical Garden
A green façade, designed by Vertiko, covers over 100 square metres and is home to various species of plants and insects throughout the year. A vertical garden that filters pollutants, isolates traffic noise and has a positive impact on microclimate and biodiversity. The building envelope features an insulating and energy-producing façade, developed in cooperation with the FKN Group and Evonik, designed in line with the principles of the circular economy. The materials used can be recycled or reused at the end of their useful life.
The material passport
The Cradle to Cradle (C2C) principle was used to ensure that the building is recyclable, free of harmful substances and easy to dismantle. As a result, building materials can be recycled or reintroduced into a life cycle after the building is demolished. Information on the materials used and their chemical composition is provided by a material passport.
