Objectives

This project aims at developing a new methodology, as the basis for future standards, to enable cost effective renovation of existing buildings while optimizing energy consumption and carbon emissions reduction.

The overall objective is to identify the optimal range of “minimization of demand” and “renewable energy harvesting” measures, i.e., level a and level b measures, according to Figure 1, in a cost/benefit perspective, in order to understand how far it is possible to go with energy conservation and efficiency measures (initially often less expensive measures) and from which point the energy harvesting from renewable sources become more economical.

The project follows a broader approach going beyond the cost effective reduction of carbon emissions and energy consumption, focusing also on the overall added value achieved in a renovation process, which means also identifying global quality improvement, economic impact of the intervention, operating cost reductions and some co-benefits like comfort improvement (thermal, natural lighting, indoor air quality, acoustics, etc.), increased value of the building and fewer problems related to building physics.

Summarizing, the main objectives are the following:
