Assessment of the energy savings potential of daylight utilization and its impact on a building energy performance

Hermano Bernardo, Sérgio Leitão, Luís Neves, Paulo Rodrigues

Abstract: This paper aims at determining the energy saving potential that can be obtained by adequate measures and investments through computational simulation, using DesignBuilder/Energyplus software. It presents the simulated values of the impact on the energy consumptions of a building, caused by artificial lighting control systems set to maximize the use of daylight and its effect on the building energy performance labelling, according to recent European and Portuguese legislation changes on this matter. The work developed was based on a real case-study of a services building located in central Portugal. The basis for the work was a computational model of the building, adequately calibrated and validated using field measurements.
