Impact of Atrium Glazing with and without BIPV on Energy Performance of the Low-Rise Building: A Central European Case Study

This article aims to investigate the impact exerted by different types of covering an atrium with glazing on energy performance a kindergarten building, provided authors as conceptual design. The considered atria included open atrium, glazed and that operated hybrid system. Additionally, following aspects were taken into consideration: effect glazing-integrated PV system (BIPV); variety thermal features represented inner boundary between conditioned unconditioned space (Uiu); air-exchange ratio (nue) balance building. Energy indicators, including demands for heating cooling (Eu), delivered (Ed), primary (Ep) indicators mode estimated moderate climates two locations building model, i.e., Warsaw (Central Poland) Ahlbeck (Northern Germany). research results prove exerts most beneficial Nevertheless, certain variables must be considered, especially space, they significantly influence total annual performance. obtained regard presence BIPV systems differ from those usually expected. is due solar-energy-transmittance value (g) modulation caused and, finally, significant reduction in passive solar-gain harvesting, which important heating-mode examined climate conditions. Taking present analysis account, it can concluded environmental effects integrated temperate are strongly influenced conditions, some cases, these solutions may not efficient enough terms costs.
