Out of 20 pilot projects started within EuroPHit, 11 case study projects with at least one retrofit step have been completed by April 2016, 9 more projects are currently ongoing and will have completed retrofit measures after the project completion. Building types and retrofit measures range from single-family homes to residential social high-rise buildings, where the EnerPHit Standard was implemented completely except for a more efficient heating system, which could not be installed for now. In other multi-family buildings, only one dwelling was improved to achieve a high efficiency and comfort level, whereas in non-residential buildings, retrofit measures consisted of the renewal and efficiency improvement of the flat roofs of only a section of the whole school building. In EuroPHit, a total budget of 26 million Euros has been foreseen to start or complete retrofit processes of more than 40.000 m² of floor area to EnerPHit Standard. | Out of 20 pilot projects started within EuroPHit, 11 case study projects with at least one retrofit step have been completed by April 2016, 9 more projects are currently ongoing and will have completed retrofit measures after the project completion.

Efficiency parameters and corresponding results are automatically transferred from PHPP into the ERP. All that needs to be done is the entry of information regarding schedule, costs and recommendation for each of the retrofit steps. By doing so it is possible to provide a comprehensive document to building owners so that they can better understand the specific concepts and the potential of the retrofit process they have started. | Efficiency parameters and corresponding results are automatically transferred from PHPP into the ERP.

• If the retrofit is carried out one building side after the other or not all elements of one component are improved in one step, this can be done by creating sub-variants (indicated with letters ‘a’ to ‘z’ in the worksheet ‘VARIANTS’) of exactly the same type and allocating these to the windows that will be modernised in the corresponding step (in this case, the south-facing windows are retrofitted first, all other windows on the north or west side will be replaced later) (Figure 6). | • If the retrofit is carried out one building side after the other or not all elements of one component are improved in one step, this can be done by creating sub-variants (indicated with letters ‘a’ to ‘z’ in the worksheet ‘VARIANTS’) of exactly the same type and allocating these to the windows that will be modernised in the corresponding step (in this case, the south-facing windows are retrofitted first, all other windows on the north or west side will be replaced later) (Figure 6). | ||

+ | |||
+ | For the 20 step-by-step retrofit projects in EuroPHit, only two projects have yet foreseen the implementation of renewable energy sources in the near future. However, a total PV implementation potential of almost 760 MWh/a has been calculated, which translates into almost 20 kWh/(m²TFA a). Future implementation of RES thereby would enable several of the pilot projects addressed in EuroPHit to be upgraded to the standards EnerPHit Plus or Premium after completion of the retrofit steps (Figure 7). | ||
