Streamlining NollCO2 2.0 compliance with One Click LCA

NollCO2 2.0: a holistic lifecycle approach

NollCO2 2.0 takes a comprehensive view of a building's environmental footprint, evaluating emissions across its entire lifecycle:

• Material production (including existing materials in renovations)
• Construction processes (including demolition and reuse in renovations)
• Operational energy
• Building services
• End-of-life (including the impact of existing materials)

Certification requires demonstrating net-zero or lower lifecycle emissions, achieved through a combination of strategies: low-carbon material selection (especially vital for renovations), energy efficiency, renewable energy integration, and carbon offsetting.

The renovation challenge: unique complexities

Renovations introduce specific challenges. Assessing existing materials, accounting for demolition and reuse, and considering pre-existing embodied carbon require specialized approaches. NollCO2 2.0 addresses these complexities with specific requirements and calculation methodologies that consider both the building’s history and future use.

One Click LCA's improved solution: streamlining compliance

One Click LCA simplifies NollCO2 2.0 certification for both new buildings and renovations, offering:

• Automated calculations: The tool automates lifecycle emissions calculations, ensuring compliance with NollCO2 2.0 methodologies and providing dedicated workflows for renovation assessments, including reuse and existing materials.
• Centralized data management:  Manage all project data — material quantities (both new and existing), energy consumption, transportation details, and demolition/reuse data — all in one platform.
• Automated reporting: Generate standardized reports meeting NollCO2 2.0 certification requirements for both project types.
• Scenario analysis: Explore various design and material choices, including reuse scenarios, to optimize emissions reductions.
• Seamless integrations: Integrate with 20+ BIM and other integrations for a streamlined workflow.
• Long-term LCAs: Project building and energy systems' climate impact reductions to 2050 and beyond, enabling long-term performance assessment.

Benefits: efficiency and data-driven decisions

With One Click LCA's enhanced tool, the entire process is streamlined, reducing time and effort for NollCO2 2.0 certification. The automated calculations provide improved accuracy while optimized resource allocation enables potential cost savings. The tool also fosters better collaboration among project stakeholders and supports data-driven decision-making for both new construction and renovation strategies.

Conclusion: driving sustainable building practices

One Click LCA's improved solution simplifies certification for climate-neutral construction, enabling architect, engineering, and construction (AEC) professionals to efficiently achieve NollCO2 2.0 certification for both new and existing buildings. By simplifying complex assessments and providing valuable insights, this tool contributes to a construction sector with reduced climate impact — supporting Sweden's overarching climate goals.
