 \\ Despite successful examples, the EnerPHit standard is still seen by many building owners as a challenge. The EuroPHit case studies aim to provide pragmatic answers, removing barriers one by one. \\ Despite successful examples, the EnerPHit standard is still seen by many building owners as a challenge.

 \\ The first barrier is the amount of investment required: if the owner can’t invest the total budget needed for envelope and building services, then they can invest step-by-step. In several EuroPHit case studies, the investment will be spread over two steps: energy efficiency finished before 2016, then renewable energy (solar thermal and/or photovoltaics) scheduled by 2020 or 2025. Other case studies will focus first on the thermal envelope and mechanical ventilation with heat recovery, before refurbishing hot water, heating and electricity. Costs associated with asbestos or fire protection should be treated as unavoidable costs as they have no impact on the economic efficiency of an EnerPHit rehabilitation [Ebel 2014]. They must still be carefully studied as asbestos removal for example, can cost up to €15000 per dwelling. \\ The first barrier is the amount of investment required: if the owner can’t invest the total budget needed for envelope and building services, then they can invest step-by-step.
