Space is an innovation centre with offices and lab activities. It has achieved NollCO2, Miljöbyggnad GOLD and WELL certifications. Reducing the climate impact of phase A1-A3 has been pursued at various levels throughout the project. Such efforts include using steel with a high recycled content, using of climate-enhanced concrete, constructing the façade in-situ with cantilever walls instead of installing a material-intensive façade system, and using a glulam and steel combination for the frame system. In general materials have been chosen based on a thorough comparison focusing on climate impact and costs. Steps were taken to reduce climate impacts during the construction phase (A4-A5), for example, using prefabricated solutions for the HDF joists to reduce waste and spillage, ensuring that the building was airtight before starting the dehydration process thereby reducing energy consumption, purchasing renewable electricity from hydropower and district, and raising project stakeholder awareness of the energy, water and waste generated by the project. Space is built with modular dimensions that provide flexibility for future floor plan changes in connection with tenant adaptations. The building layout and the building’s ventilation system design enhance this flexibility. The protection and durability of materials have also been considered, for example by protecting the wooden façade structure with a double façade and using durable and high-quality surface finishes.

The results shown here are from the NollCO2 certification. The system boundary covers almost all life cycle modules, where the product stage is dominating followed by energy consumption. All materials are reported, including building energy systems/installations such as electrical cables, HVAC, water pipes, sewage pipes, heating systems, lifts and solar PV panels. The NollCO2 report states that end-of-life stages, C1-C4, are included in the assessment. However, the impacts are all set to zero.
In the second figure, Operation includes B6 and B7, while materials include A1-A5, B4-B5.
B6 and B7 have very low impacts, mainly because in the used version of the NollCO2 certification the impact from energy use is reduced annually until assumed zero in 2050.
In the third figure, Upfront includes A1-A5, scenarios include B4-B5, and D is shown separately had it been included in the assessment.
