Report on optimal packages of solutions

Summary
This short document will contain the results of the optimization work carried out in Task 3.3 “Calculations on reference buildings and identification of optimal integrated packages of solutions”, where the needed investment and savings related to each renovation measure (see D3.3) will be calculated on the reference buildings (see D3.2) and on different climate zones (see D3.1), in order to define at least 5 optimal packages of solutions, which will include an evaluation of an optimal step-by-step renovation approach. The optimization will be done in terms of the minimum investment and minimum amortization period that will lead to optimal packages for step-by step refurbishment in order to develop a MedZEB step-by-step technical approach, as an alternative to traditional refurbishment approach in order to foster the market uptake.
