+ | ===== Passive House window certification: | ||
+ | |||
+ | One of the problems when Passive House was just getting started was that there were not yet any windows on the market with high enough quality. The required thermal qualities could only be achieved by individually improving standard windows, at times right on the construction site. To improve the situation, the Passive House Institute established a window certification program and worked together with manufacturers to develop high-quality windows for market launch. By now, more than 130 windows have been certified in 23 countries (as of February 2013), with interest in window certification growing particularly fast in the last few years; 39 new components were certified in 2013 alone. The dashed line in Figure 1 shows this impressive upswing. At the same time, products are constantly becoming both better and more affordable. Improvements in windows and glazing in particular present a lot of new opportunities. While the first Passive House buildings tended to stick to the classic passive-solar " | ||
