The EPBD recast text, published today in the Official Journal, states (art. 9) that by the end of 2020 all new buildings should be "nearly zero - energy buildings", i.e. with very high energy performance and their energy requirements covered by renewable energy sources to a significant extent. Member States are expected to draw up plans for increasing the number of nearly zero-energy buildings, however an exact, numerical definition of nearly zero is not given, allowing space for national interpretations.
What are available definitions and numerical indicators on passive and very low energy buildings and are they considered to fulfil the requirements of the EPBD recast definition on nearly zero-energy? Do existing national policies on passive house and very low energy buildings meet the EPBD recast requirements or even better transcend them? And what financial or other policies are already being used to stimulate the increase of very low energy buildings?

carbon neutral definitions
Hello All,
this is great! I am new in the area :) I have been working on a research project with the Donau krems university in Austria on this same topic. What I have discovered so far about the definition of "carbon neutral" is that... there is NO official definition as we speak. Many countries and governement pretty much make up their definition and abide by it. Some countries are a lot more critical, as they have established a procedure in order to reach a certain target, and others favor major corporations and make their life easier. Some countries and or corporations assume carbon off setting is as good as carbon neutrality. I am trying to compare 5 different countries on this topic: Carbon neutral in Buildings. I am searching for regulations, standards, units of measurement etc. any comments?
What is the definition of energy neutral
In the Netherlands there is discussion about Energy Neutral. There is the ambition of Energy Neutral in 2020. Is this the total Energy use including household appliances or only space heating? The definition of Agentschapnl is that Energy neutral is that the total energy use is zero or energy producing.
