-It is not always possible to achieve the Passive House Standard (new constructions) for [[:planning:refurbishment_with_passive_house_components:passive_house_refurbishment_-_introduction|refurbishments of existing buildings]], even with adequate funds. For this reason, the PHI has developed the “EnerPHit – Quality-Approved Energy Retrofit with Passive House Components” Certificate.
+{{ :picopen:enerphit_classic_new.png?200|}}
-Significant energy savings of between 75 and 90 % can be achieved even in existing buildings, for which the following measures have proved to be particularly effective [Bastian 2022]:
+It is not always possible to achieve the fulll Passive House Standard for [[planning:refurbishment_with_passive_house_components|refurbishments of existing buildings (introductory article)]], even with adequate funds. For this reason, the PHI has developed the **EnerPHit Standard** – Quality-Approved Energy Retrofit with Passive House Components - as quality assured certification scheme for renovation of existing buildings. It can be applied on one go or as a phased approached using the EnerPHit retrofit plan.
-  * improved thermal insulation (based on the principle: if it has to be done, do it right)
+[[:certification:enerphit:EnerPHit building renovation]]
-  * [[:planning:refurbishment_with_passive_house_components:thermal_envelope:minimising_thermal_bridges|reduction of thermal bridges]] {{:picopen:members_only.png?20}}
-  * considerably [[:planning:refurbishment_with_passive_house_components:thermal_envelope:airtightness|improved airtightness]] {{:picopen:members_only.png?20}}
-  * use of high quality [[:planning:thermal_protection:windows|windows]] (there is no reason why Passive-House-suitable windows should not be used whenever the opportunity arises)
-  * [[:planning:building_services:ventilation:basics:types_of_ventilation#the_convenient_solutionsupply_and_exhaust_air_systems_with_heat_recovery|ventilation with highly efficient heat recovery]] (again, Passive-House-suitable systems are very recommendable)
-  * efficient heat generation
-  * use of renewable energy sources
-These are exactly the same measures that have proved to be successful in new constructions. A number of examples demonstrating the application of high-efficiency technology in existing buildings have become available in the meantime. The Passive House Institute has advised on the implementation of several projects and carries out measurements in modernised buildings.
+Significant heating/cooling energy savings of between 75 and 90 % can be achieved even in existing buildings, for which the following measures have proved to be particularly effective [Bastian 2022]. The general approach to prevent lock-in and achieve high quality cost-effective solutons is: **If you do it, do it right!**
-To know more about the EnerPHit-Standard you can also visit the corresponding section in the Passive House Institute's website:
+  * Improved thermal, similar to Passive House newbuild levels
+  * [[:planning:refurbishment_with_passive_house_components:thermal_envelope:minimising_thermal_bridges|Reduction of thermal bridges]]
+  * Considerably [[:planning:refurbishment_with_passive_house_components:thermal_envelope:airtightness|improved airtightness]]
+  * Use of high quality [[:planning:thermal_protection:windows|windows]]: Use of Passive-House-suitable windows whenever the opportunity arises.
+  * [[:planning:building_services:ventilation:basics:types_of_ventilation#the_convenient_solutionsupply_and_exhaust_air_systems_with_heat_recovery|Ventilation with highly efficient heat recovery]]. Again, aligned with Passive House newbuild efficiency recommendations
+  * Efficient heat generation
+  * Use of renewable energy sources. Depening on use of renewable energy, EnerPHit is also availble as [[certification:passive_house_categories|certification classes Classic, Plus and Premium]].

+These are exactly the same measures that have proven to be successful for new constructions. A number of examples demonstrating the application of high-efficiency technology in existing buildings are available, including monitoring data as proof of concept of the achieved energy savings. You can find examples of implemented EnerPHit buildings in the online [[http://www.passivhausprojekte.de/index.php?lang=en | Passive House Database]] (advanced search, filter by Energy Standard / building type for EnerPHit projects).
