The Energy Performance of Buildings Directive (EPBD) introduces the Building Renovation Passport (BRP) to help plan energy renovations, with a new method developed to schedule cost-effective interventions based on financial circumstances, proven effective through a Portuguese case study.
The revised Energy Performance of Building Directive (EPBD) introduced the Building Renovation Passport (BRP), a voluntary scheme for planning energy renovations.
However, a systematic methodology to schedule interventions effectively from a financial perspective was lacking. This study, titled 'Building renovation Passport: A new methodology for scheduling and addressing financial challenges for low-income households', develops a method based on evaluating investment cost-effectiveness and considering the owner’s financial situation.
By calculating Net Present Value (NPV) and payback time, it helps plan energy renovations towards a nearly Zero Energy Building target.
Applied to a Portuguese case study, the method proves effective in scheduling renovations, reducing energy poverty, and building emissions. State aid also accelerates implementation, making renovations more feasible for households.
