D03 - How To Say Zero in Swedish: NollCO2 Climate Neutral Building

Abstract Text:

Before the landmark agreement at COP21 to reduce global warming to +1.5°C, the Swedish government established Fossil Fuel Free Sweden, an initiative to make Sweden the world’s first fossil fuel free welfare state by 2045. Enter NollCO2, Sweden’s first certification system for climate-neutral buildings. Starting in 2016, Sweden Green Building Council (SGBC) began development of NollCO2, or Zero CO2. The need for a universal and consensus-driven definition of net zero, encompassing both operational and embodied carbon – for all life cycle phases – would come to anchor prerequisites and criteria in NollCO2. The NollCO2 system is simple but challenging. Projects must fully address just three criteria: calculate the project’s total CO2 balance, limit CO2e for building products to 240 kg/m² (conditioned floor space), and limit CO2e for the construction process to 60kg/m². In addition, all CO2e must be compensated over the project’s lifespan. Three pilot projects are testing the first version of NollCO2: one grocery store, one speculative Class A office building and one courthouse/ office, ranging in size from 2250m²-25000m² (24,000-270,000sf). This variety of buildings will determine the real-life practicality of NollCO2’s criteria by testing the current market while simultaneously driving development of new tools, systems and products. The rigours of NollCO2 will require deeper engagement with all project partners, from owners to consultants, builders, manufacturers, operators and tenants to realize minimal CO2 emissions throughout the building’s full life cycle. The pilot projects will describe their approaches, successes and challenges with operational and embodied carbon, including the tools and processes to bring the projects within NollCO2’s strict requirements. The projects will also share how NollCO2 assisted project owners in achieving or surpassing their own corporate goals on carbon reduction and accountability, national initiatives like Fossil Fuel Free Sweden 2045, and global objectives like Science Based Targets.

Learning Objectives:

Describe the definition of climate neutral buildings as used in the Swedish market, including how it is applied in different life cycle phases.

Relate the challenges of applying strict limits on embodied carbon in building materials for different building structural systems and occupancy types.

Describe the challenges of defining climate compensation strategies from the perspective of multiple interested parties, such as government and industry.

Apply the argument for climate-neutral buildings in relation to corporate, national and international goals and objectives.
