-Presently our main concern is the reduction of greenhouse gasses, GWP (which PE is related to), and the transition to a non-fossil-based energy supply, which will take place over several decades. Buildings constructed today will have longer life cycles than just the transition phase to a non-fossil based society and hence they will also be used in the post-transition era.  +Presently our main concern is the reduction of greenhouse gas emissions and the transition to a non-fossil-based energy supply, which will take place over several decades. Buildings constructed today will have longer life cycles than just the transition phase to a non-fossil based society and hence they will also be used in the post-transition era.  
-During the transition phase, PE and GWP factors are changing, and will finally approach zero as we reach a society powered by 100% renewable energy. Does this mean, buildings, regardless of their construction, become better and better and their (final) energy use doesn’t matter? +During the transition phase, PE and  CO<sub>2</sub>-equivalent emission factors are changing, and will finally approach zero as we reach a society powered by 100% renewable energy.

 The above-mentioned assessment methods suggest this, but obviously, this is not the case. Renewable energy must be generated, delivered, and often stored. Renewable energy needs infrastructure and space which will become a decisive limiting factor. We want affordable renewable energy for all, and for all applications. For these reasons, energy use must be efficient: energy efficiency is the prerequisite for effective renewable energy supply. Bearing  in mind that a third of the total energy consumed in developed countries is required for operating buildings, we realise how important this sector is for the transition, and obviously the traditional assessment methods are not adequate for this future scenario.  The above-mentioned assessment methods suggest this, but obviously, this is not the case.

 In this way, PER factors depend only on the location of the building, the application (e.g. heating, cooling or specific electricity), and the final energy carrier. They do not depend on the actual supply system. They are local physical parameters, such as climate data. In practice, they are automatically provided with the PHPP, in the same way the climate data sets are. In this way, PER factors depend only on the location of the building, the application (e.g. heating, cooling or specific electricity), and the final energy carrier.

 For both energy demand and, if applicable, generation at the building site, the Primary energy renewable is calculated. For the assessment, these have different reference values. For both energy demand and, if applicable, generation at the building site, the Primary energy renewable is calculated.

 The primary energy renewable demand is measured against the value of the service, which is represented by the useful space of the building, the so-called “Treated floor area (TFA)”. The primary energy renewable demand is measured against the value of the service, which is represented by the useful space of the building, the so-called “Treated floor area (TFA)”.

 The primary energy renewable generation is measured against the limited resources which the building possesses, which is the area it occupies, so that it is no longer available for other uses. We call it the “Projected building footprint (PBF)”. The primary energy renewable generation is measured against the limited resources which the building possesses, which is the area it occupies, so that it is no longer available for other uses.

-Renewable energy is the ideal complement to the energy efficiency of the Passive House Standard. In order to provide reliable guidance for this combination, the Passive House Institute has introduced new categories for its building certification; in addition to the established “Passive House Classic”, there are (starting with the publication of PHPP 9) the Passive House Plus and Passive House Premium classes. A new evaluation procedure, focusing on Primary Energy Renewable (PER), serves as the basis for the extension of Passive House Certification. +
