A taste of what to expect at the upcoming International Passivhaus Conference

19th International Passivhaus ConferenceDetails of new Passivhaus criteria will be elucidated on at the upcoming International Passivhaus Conference, now in its 19th year, held in Leipzig this April, along with honouring component award winners and a packed programme focusing on cost-efficiency.

Component Award Winners

Joint 1st prize went to:

The products had to show a degree of flexibility since refurbishments are often carried out in a step-by-step manner. Therefore, ideal windows had to deliver excellent results during the transitional period as well as after the completion of all refurbishment measures.

The winners are to be honoured at the Conference proceedings.


New categories

The new categories to the Passivhaus standard acknowledge that renewable energy is the ideal complement to the efficiency of the Passive House Standard, and provide reliable guidance for this combination.


Passivhaus Classic

Passivhaus Plus

Passivhaus Premium


Previous Passivhaus Standard

Energy generated equals energy required

Energy generated significantly exceeds energy required

Heating Demand

≤15 kWh/(m2a)

≤15 kWh/(m2a)

≤15 kWh/(m2a)

Primary Energy Renewable

(replaces primary energy demand)

≤60 kWh/(m2a)

≤45 kWh/(m2a)

≤30 kWh/(m2a)

Renewable Energy Generation 


≥60 kWh/(m2a)

≥120 kWh/(m2a)

The overall demand for renewable primary energy (Primary Energy Renewable) will be used instead of the primary energy demand, which was previously used. In the case of the Passive House Classic category, this value will be 60 kWh/(m²a) at the most. The respective PER will take into consideration energy storage capacities, and associated energy losses. A new evaluation procedure which also considers energy generation by the building itself will serve as a basis for this. Detailed information on the new Passive House categories and the PER evaluation procedure:

Using specific examples, the Passive House Institute will demonstrate the implications of the new Passive House categories and the PER system for project planning: Dr. Benjamin Krick will calculate which specific energy related optimisations would be necessary in order to achieve the new Passive House categories for some existing buildings. Jessica Grove-Smith will show how the PER factors were developed for the newest version of the tried and tested planning tool PHPP (Passive House Planning Package).

New Passivhaus Categories

The introduction of the new categories will ensure the Passivhaus Standard is not only an attractive solution for the energy transition, but also a blueprint for the Nearly Zero-Energy Building stipulated in the European Buildings Directive, which will come into effect in 2021.

That leaves us six years to get our act together!

We will be briefing upon these new categories in more detail after the International Conference with upcoming tutorials later this year.
