【 摘 要 】

With more than 30% of the total global greenhouse gas emissions generated from the constructions sector, fostering sustainable buildings is one of the key levers in order to address the highly urgent topic of climate change. The German Sustainable Building Council (DGNB) is striving to make a significant contribution to the achievement of the national targets defined in the Paris Agreement in order to limit global warming to well below 2°C. The key to achieving these targets for the building sector lies in fostering climate neutral operation of new construction and, even more challenging, in realizing a carbon neutral building stock by 2050. With the discussion paper for a new format of the German Energy Code "GEG 2050" claiming the introduction of a "Building Emissions Law 2050", DGNB has started a much-needed debate on shifting the focus of performance metrics from "primary energy demand" to "CO2-emissions". In order to translate the requirements into building practice and to make their implementation assessable and measurable, the DGNB has developed a "Framework for Carbon Neutral Buildings and Sites", which includes three main parts: 1. Carbon Accounting Rules defining consistent calculation rules for buildings and sites, 2. Carbon Disclosure Rules with specific rules regarding the type and the content of the communication towards the customer and 3. Carbon Management Rules establishing a roadmap to carbon neutral building operation ("Klimaschutzfahrplan") that demonstrates a net zero carbon balance by latest 2050, using a linear trajectory to zero from today onwards. The Framework has been published as a preview version in May 2018 and now is currently being revised within a pilot phase.
