|Rising energy prices and public interest in energy savings stimulated by Zelená úsporám program resulted in a significant increase in the number of low energy and passive houses. Companies interested in this type of construction show that this trend is promising, not only for commercial but also for residential buildings.
|Recently, there have been nearly 100 passive houses registered in the Passive House Centre database. Director of the Centre, Ing. Jan Bárta, commented on the numbers: "Our database show approximately one quarter of all passive house built. Moreover, according to the latest data from the Zelená úsporám program, there are over 500 applications submitted for passive houses (the houses are not built yet). The current trend in Czech Republic is so far mirroring trends abroad - every year the number of passive houses is roughly doubled. "||

|Thus, in a couple of years, the number of passive houses in the Czech Republic could reach four-digit number.
The number of low-energy buildings (with specific annual heat demand for heating lower than 50 kW/m2) is also increasing rapidly. The exact number is however difficult to determine - some companies advertise low-energy buildings with no evidence of appropriate parameters. Additionally, besides new buildings the reconstructions should also be taken into account.
