With a structured approach, we can plan, construct and operate buildings today so that they become climate-neutral or, ideally, climate-positive.

Our guide presents the relevant fields of action under two optimisation aspects: How do I achieve climate-neutral building operation? How can I achieve climate-friendly building construction?

Background knowledge

When it comes to the climate protection contribution of buildings, it is debatable whether neutral is already good enough.

Climate-neutral buildings also have a positive effect on the climate

In carbon accounting, as defined in the "Framework for climate-neutral buildings and sites" compiled by the DGNB, the term neutrality is synonymous with the mathematical target value of zero as a minimum requirement. If one leaves the purely balance sheet-based view, "neutral" only inadequately expresses what the buildings that are already climate-neutral today actually achieve: a positive contribution to climate protection. The DGNB has set itself the goal of highlighting these exemplary projects, presenting their success factors and thus inspiring others. For this reason, DGNB has created the "Climate Positive" award.

This is how climate-positive works

Buildings can already be planned, realised and operated in such a way that they are climate-positive - that is the good news that cannot be repeated often enough. However, economic solutions for achieving a climate-positive building certainly do not consist of simply working through and implementing measures without taking into account the overarching context. For this reason, the rather reactionary approach that prevails today urgently needs to be replaced by a sensible, systematic approach.
Systematic, climate-positive action means that every decision and measure must be evaluated and designed with the following aspects in mind

  • Minimisation of the total energy requirement
  • Efficient generation of energy
  • Selection of energy sources with the lowest possible CO2 intensity

Conclusion

Climate-neutral and, ideally, climate-positive buildings are active elements of the climate and energy transition. Independent and resilient, they not only reduce the carbon footprint of the building, but also that of the energy sector.

Climate positive: now!
The publication "Climate-positive: Now!" shows how every building can make a contribution to climate protection and provides assistance to enable pragmatic and practical implementation. It provides more detailed background information on why the construction and property sector plays a key role in climate protection and why we need a paradigm shift in the way we treat our buildings. It also identifies areas of action that have a significant influence on making buildings climate-neutral.
Your path to a climate-neutral building
The DGNB is developing a practical guide to actively support all stakeholders in taking action and constructing and operating their buildings in a climate-neutral way. In twelve concrete steps, it explains how this can be achieved, from CO2 balancing to the creation of a climate protection plan and the implementation of climate protection measures. (in German)

Framework for carbon neutral buildings and sites
In the framework, the DGNB has compiled its definition of climate neutrality and the associated explanations regarding procedures. The aim is to create clarity on the market and to inform all stakeholders about effective optimisation approaches for reducing the CO2 emissions of their properties. Among other things, the framework describes the rules for CO2 balancing of buildings and locations. It also serves as a basis for the development of building-specific climate protection strategies. Requirements and options for CO2 reporting and quality assurance are also presented.

Toolbox "Carbon neutral building"
Information, recommendations for action and instruments for planning, constructing and operating buildings and neighbourhoods in a climate-neutral way.

Founded in 2007, the DGNB is now the largest network of its kind in Europe and number 2 worldwide, with more than 2,800 member organisations. The overriding goal of the non-profit association is to actively shape the transformation of the construction and real estate industry, to promote understanding of the need for sustainable building and to anchor it in the consciousness of the general public. The DGNB is committed to proven good buildings, liveable districts and a sustainable built environment.
