 The EnerPHit standard can be reached by meeting energy demand performance limits or, alternatively, by meeting minimum efficiency performance levels for individual building components. Depending on the project, these two approaches allow flexibility to implement a retrofit concept that makes the most sense economically and ecologically, whilst ensuring a high level of efficiency and thus preventing energy lock-in. For the **component method**, individual components must achieve minimum efficiency values similar to the requirements for certified passive house [[:certification:passive_house_suitable_components|component certification]]. The **energy demand method** is similar to the Passive House newbuild standard, but with slightly higher target values to allow for the special challenges of retrofitting existing buildings.
-A stepped or phased retrofit allows for a gradual improvement of a building's energy efficiency, with costs and effort spread over time. The **EnerPHit Retrofit Plan (ERP)**, which is based on the PHPP balancing tool, is a very valuable tool for planning and coordinating the various retrofit steps.
