The influence of daylighting in buildings with parameters nZEB: application to the case study for an office in Tuscany Mediterranean area

The paper deals with the contribution of the consumption for lighting on the global energy consumption, referred to the case study of an office building defined by the Italian Heat Technology Committee, to which the reference values nZEB for thermal transmittance and solar control were applied. The analysis highlights the importance of using daylight control systems to reduce the energy need and achieve the nZEB standard Improving the use of daylight in buildings results in an energy saving strategy because lighting accounts for approximately 6 to 46 % of the global electric energy consumption.
