- Castellum will construct an office building in central Örebro for the Swedish Police Authority.
- The building to be constructed entirely of wood and certified in compliance with the new NollCO2 certification.
A primary objective is for the building to have net-zero CO2 emissions throughout its lifetime.
The project is calculated at a cost of approx. MSEK 225 – including acquired building rights of MSEK 15 – and the investment will result in an annual leasing income of MSEK 15.
What is NollCO2 certification
The NollCO2 certification was developed by the Sweden Green Building Council as an enrichment level of Miljöbyggnad, BREEAM, LEED and Svanen.
This is a standard for more sustainable buildings with net-zero greenhouse gas emissions during the building’s entire life-cycle.
Castellum has participated in SGBC’s development activities related to the NollCO2 certification.
How climate neutrality will be achieved for this building
Climate neutrality is primarily achieved by building the core structures in wood instead of the traditional steel and concrete.
Utilization of wood means that emissions will be 40% lower compared with traditional construction.
A further solution for achieving climate neutrality will be to install sun panels on the roof.
Construction start is planned for the summer of 2020, with completion scheduled for mid-2022.
Castellum’s climate objectives include becoming 100% climate neutral by 2030, in compliance with national goals for a fossil-free Sweden.
