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.
The Passive House is the world’s prominent standard for energy-efficient building and construction; the savings in heating costs are generally over 80 % in contrast with the national statutory requirements for brand-new constructions. The heating demand is less than 15 kWh/(m ² a) in the Passive House, based upon the “heated/cooled functional area” (TFA, roughly: the living area).
The approach for developing a Passive Home for a specific building job and a specific environment is explained in typically available literature– the tools needed for this, like the PHPP for example, are available on the market. There are numerous Qualified Passive House Components available– for main European environment zones along with for other environments. Based on the requirements for Passive Homes, there are also requirements for older structures.
