The project is planned and built for a single tenant who rents the entire facility including one storage facility, one cross dock facility and office functions. According to the sustainability goals of the property owner Swedish Logistic Properties, the project is certified according to Miljöbyggnad Silver and NollCO2. NollCO2 sets a building-specific baseline and reduction threshold for the life-cycle stages A1-A3 and a general threshold for the life cycle stages A4-A5. Embodied carbon emissions are balanced to net zero by compensation measures, in this project composing of the photovoltaic system installed on the building’s roof. The main goal of the project was to reduce material and in the next step select smart materials with low embodied carbon to reduce the buildings carbon impact. The LCA was conducted according to the NollCO2 principles and an early calculation pinpointed carbon-intensive materials and resulting improvement potentials. Elements with a high carbon impact were improved by choosing materials with low embodied carbon. The main stakeholders in the LCA calculation and improvements were the contractor and the LCA consultant. The biggest improvements were found in the early stages and when dimensioning systems as well as choosing subcontractors and materials. The project will follow up the carbon intensity after three years, where the building energy use intensity and carbon impact from energy use will be analysed.

The results shown here are from the NollCO2 certification. The system boundary includes the product and use stages. Building services are modelled in detail (lifts and escalators, electricity system, HVAC system, renewable energy systems, water system, sewage system).
In the second figure, Operation includes B6 and B7, while materials include A1-A5, B4-B5.
In the third figure, Upfront includes A1-A5, scenarios include B4-B5, and D is shown separately, had it been included in the assessment.

It is not specified if the frame (beams and columns) is interior or exterior. There are also stairs in the model, but they are not included in the figure because their impacts are smaller than internal doors. Interior finishes include floors, walls finishes and coverings and ceilings.

Building element quantity per building reference area is a measure for the material intensity, while element impacts per element quantity is a measure for the elements’ carbon intensity relative to their weight.
