Evaluation of energy Efficient Refurbishment of Residential Buildings in Southern Europe Based on the Cost-Optimal Methodology
In line with the European Energy Performance of Building Directive (EPBD), this paper aims to calculate the cost-optimal energy performance of a residential building in southern Europe, more precisely in Portugal, taking into consideration thermal and lighting (daylighting and artificial lighting) refurbishment solutions. The economic calculation method used considers the initial investment costs, the running costs (including annual maintenance costs, operational costs, energy costs and periodic replacement costs), greenhouse gas emissions costs and disposal costs.
