Evaluation of photovoltaic windows with luminescent solar concentrators for zero-energy buildings in Santiago de Chile

Abstract:

Glasses with luminescent solar concentrators (LSC) allow to develop windows with perimeter photovoltaic collection, as building- integrated photovoltaics (BIPV). This work assesses its application in office buildings in Santiago de Chile, to contribute in zero-energy goals, reviewing energy plans for building in Europe and Chile, zero-energy concepts in buildings and defining a study model in Santiago de Chile. Then the performance and energy generation are simulated with different constructive properties, layout and efficiency of the windows. The analysis suggests that this technology, when used in wide areas over the sunniest façades, can provide up to 40% of building consumption, for longitudinal buildings with energy-efficient envelope and equipment, in addition to contributing to shading. It is thus demonstrated that, by regulating the building and forming large windows adequately arranged, this technology can contribute significantly to reach zero-energy buildings goals.
