Sustainability Report

• IXCAMPUS is BBCA (Low Carbon Building) certified. Available carbon data records 1,870 tonnes of CO2 emissions avoided and a 25 percent reduction in CO2 emissions through the use of low-carbon concrete. 
• The project uses approximately 1,353 cubic metres of timber.
• Timber construction includes glulam post-and-beam structures, 10,000 square metres of CLT floor slabs, ribbed CLT box elements, timber-frame walls, and timber cladding.
• The building envelope includes approximately 8,000 square metres of timber-frame facades, 1,815 square metres of straw insulation, and 3,100 square metres of wool insulation. 
• For the Grande Orangerie, Baumschlager Eberle Architects and facade engineers Bollinger + Grohmann developed prefabricated timber-frame facade panels measuring 12 metres high, 3.3 metres wide, and 700 millimetres deep. The panels include the windows and glazing. Bouygues and Mathis coordinated the structural tolerances, connections, weather protection, transport, and assembly, and the complete envelope of the Grande Orangerie was assembled in six weeks.
• Reuse includes sanitary and technical equipment, lighting fixtures, carpets, and ceramic tiles.

Principal suppliers and contractors

• Mathis — timber-frame walls, wool insulation, and passive solar-shading elements
• Charm’Ossature — straw-insulation panels
• Stora Enso — glulam post-and-beam structures, CLT floor slabs, and ribbed CLT box elements
• Piveteau — timber cladding
• Cyneo — reused sanitary and technical equipment, lighting fixtures, carpets, and ceramic tiles

• IXCAMPUS complies with RE2020. The Incubator’s calculated primary energy consumption is 11 percent below the RE2020 maximum, while the Grande Orangerie is 29 percent below the maximum. There is no gas use.
• The facade design was studied through design variants, daylight simulations, and thermal studies considering facade depth, window ratio, shading, and room depth.
• The deep timber structures shade the glazing and reduce summer solar gains while maintaining natural daylight in the working and learning spaces. The Grande Orangerie’s timber fins provide solar shading and contribute to the lateral bracing of the building, while the Incubator’s deep Douglas fir facade reduces direct solar gain during the summer.
• The classrooms and office spaces do not use conventional air conditioning. An adiabatic cooling system combined with the ventilation system provides temperature control.
