Combining Sufficiency, Efficiency and Flexibility to Achieve Positive Energy Districts Targets
Energy efficiency, generation from renewable sources and more recently energy flexibility are key elements of present sustainability policies. However, we are beginning to see a recognition of the need to couple technological solutions with lifestyle and behavioral changes, sometimes labeled under t...
