Performance of a Building Integrated Semitransparent Photovoltaic Façade on a Residential House in Northern Europe
Semitransparent photovoltaic (PV) façade is a good alternative to the popular rooftop PV systems. In addition to the electricity generation the semitransparent PV facade regulates the indoor temperature and lighting conditions, alters the aesthetics, and acts as a noise barrier. In this paper we investigate the influence of semitransparent PV façade on a single family house in the Estonian climate. We compare the energy performance and the indoor environment of three modifications of the test house with IDA ICE simulation software: base version without window shadings, version with horizontal shades, and version with semitransparent PV façade. The results of the simulations show that the overheating of the base version can be equally well eliminated by the horizontal shades or the semitransparent PV façade. In contrast to the horizontal shades, the PV façade blocks the useful solar gain in wintertime. This results in higher heat demand by 60% and higher artificial lighting demand by 11%. Nevertheless, the extra energy demand is fully compensated by the PV electricity production, which makes the house a plus energy building. In addition to the energy consumption, the PV façade decreases the outdoor to indoor noise propagation by 32 dB.
