Guidelines on how to approach the energy-efficient renovation of shopping centres

A shopping centre is a building, or a complex of buildings, designed and built to contain many interconnected activities in different areas. Shopping centres have special peculiarities as they vary in their functions, typologies, forms and size. Within the retail sector, they are of particular interest because of their structural complexity and multi-stakeholders’ decisional process, their high energy savings and carbon emissions reduction potential, as well as their importance and influence in shopping tendencies and lifestyle. In order to efficiently exploit a shopping centre energy potential, every retrofitting should involve a careful analysis of the building peculiarities in all fields, from the economic features until the socio-cultural ones. The use of building energy simulations can help evaluate the balance between gains and losses and the energy uses and test design options and solution-sets. The CommONEnergy guidelines are a step-by-step handbook for the renovation of shopping centres, resulting from the four years of research of the project. Starting from an analysis of shopping centres’ features and drivers for their renovation, CommONEnergyguidelines go through processes, modelling and tools developed by the projec
