You want to get passive house certification, but you don't know exactly what you need to do. Here you fint all you need to meet the strict Passive House certification criteria.

In this moment there are more than 30 Passive House accredited Certifiers in the world. Why you need a Passive House Certification? The certification provides an important and visible form of quality assurance. The first criteria: the Heating Energy Need is not to exceed 15 kWh per square meter of net living space (dealt with flooring location) each year or 10 W per square meter peak demand. In climates where active cooling is needed, the Area Cooling Energy Demand requirement roughly matches the heat need requirements above, with an additional allowance for dehumidification. The second criteria: the Renewable Main Energy Need (PER, inning accordance with PHI technique), the overall energy to be used for all domestic applications (heating, hot water and domestic electricity) should not exceed 60 kWh per square meter of treated floor area each year for Passive Home Classic. Three: In regards to Airtightness, an optimum of 0.6 air modifications per hour at 50 Pascals pressure (ACH50), as validated with an onsite pressure test (in both pressurized and depressurized states). Four. Thermal comfort should be fulfilled for all living locations throughout winter along with in summertime, with not more than 10 % of the hours in a given year over 25 ° C. For a complete introduction of general quality requirements (soft criteria) see Passipedia.

Enjoying teamwork with Fergus @comfortforyou on #Passivhaus in Mayo

I’m currently working alongside Fergus (Certified Passivhaus Consultant) at Comfort Solutions providing Passivhaus consultancy on a new house in Mayo.

I’m not the architect on this one but we’re providing Passivhaus/PHPP modelling together on a new one-off house in Mayo (more details at later stage).

Below is where we’re currently at:

Looking good so far. Any comments welcome.
