Abstract

The European Green Deal's Renovation Wave of the building stock opens up opportunities to companies in the real estate sector. The use of energy efficient lighting technologies and intelligent control systems significantly contributed to electricity savings and reducing carbon dioxide emissions in the construction sector without requiring deep interventions inside the buildings. To assess the economic revenue of the investment, it is necessary to consider both the financial savings related to electricity consumption and the resulting impact on heating and cooling consumption. Despite the wide acceptance of energy-efficient lighting, the thermal effect on the buildings in terms of heating and cooling load has not been investigated. This study addresses the impact of lighting efficiency interventions on heating and cooling consumption in different types of buildings within various climate zones through dynamic simulations compliant with the UNI EN 52016:2018 standard. The research outcomes provide a set of regression models valuable for carrying out simplified feasibility studies considering electric and thermal impacts of lighting renovation measures.
