Stopray Vision \u2013 for the vision part of the facade \u2013 is a colour-neutral range of solar control glass products developed by AGC Glass Europe. Thanks to an outstanding selectivity2<\/sup> of around 2, it combines excellent protection from excessive heat<\/strong> (low solar factor3<\/sup>) with high light transmission. In addition, Stopray Vision features a particularly low Ug-value, preventing heat loss. In both winter and summer, Stopray Vision delivers substantial energy savings<\/strong>.<\/p>\n\n\n\n To further improve a building\u2019s energy efficiency, consider using BIPV solar glass for the spandrels. Stopray Active \u2013 part of AGC\u2019s SunEwat range \u2013 features\u00a0photovoltaic<\/strong>\u00a0(PV) cells embedded behind a Stopray Vision coating and can seamlessly match the facade\u2019s vision elements (windows) to deliver an\u00a0aesthetically<\/strong>\u00a0superb project while also generating electricity. This kind of fully integrated facade contributes towards compliance with nearly zero-energy building standards and helps earn credits for green certifications, such as BREEAM and LEED. Moreover, the payback period for the BIPV solution should be less than 10 years, as demonstrated in the article entitled\u00a0BIPV Glass and Carbon Neutrality<\/a>. If the BIPV solution is not cost effective for a poorly oriented facade, a uniform appearance can be maintained across the entire project by specifying the same glass panels without built-in PV cells.<\/p>\n\n\n\n In a curtain wall, you must take into account the fact that double or triple BIPV glazing requires some space for the electrical components. The box housing the glazing\u2019s electrical components along with the connectors and cables cannot emerge from the back of the insulating glass unit as is the case in a conventional photovoltaic panel, since that would allow the insulating gas inside the glazing unit to escape. As a result, the small electrical components should ideally be positioned on the upper edge of the glazing unit. Bear this in mind when designing your facade so as to integrate the electrical components seamlessly into the curtain wall.<\/p>\n\n\n\nCurtain walls: electrical components<\/h3>\n\n\n\n
