Developing a cost-effective method for energy renovation scheduling under the Building Renovation Passport framework
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.
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.
