Jak rozeznat n\u00edzkoenergetickou a pasivn\u00ed d\u0159evostavbu?
Co je pasivn\u00ed d\u016fm a jak se vlastn\u011b li\u0161\u00ed od n\u00edzkoenergetick\u00e9ho?

Z\u00e1kladn\u00edm rozd\u00edlem mezi pasivn\u00edmi a n\u00edzkoenergetick\u00fdmi domy je jejich ro\u010dn\u00ed spot\u0159eba energie na vyt\u00e1p\u011bn\u00ed. Spot\u0159eba n\u00edzkoenergetick\u00e9ho domu se mus\u00ed pohybovat mezi 15 \u2013 50 kWh\/m2 za rok. Aby stavba dosahovala standard\u016f pasivn\u00edho domu, mus\u00ed b\u00fdt jej\u00ed spot\u0159eba tepla na vyt\u00e1p\u011bn\u00ed men\u0161\u00ed ne\u017e 15 kWh\/m2 za rok. To je v porovn\u00e1n\u00ed se standardn\u00ed zd\u011bnou novostavbou a\u017e desetkr\u00e1t m\u00e9n\u011b.<\/p>\n\n\n\n

Koncept n\u00edzkoenergetick\u00fdch d\u0159evostaveb
Jak ale n\u00edzk\u00e9 spot\u0159eby energie v d\u0159evostavb\u011b dos\u00e1hnout? Kl\u00ed\u010dov\u00fd je architektonick\u00fd n\u00e1vrh stavby. Zapomenout ale nesm\u00edte tak\u00e9 na kvalitn\u00ed izolaci, tvar domu, orientaci zasklen\u00fdch ploch nebo volbu materi\u00e1l\u016f. Ide\u00e1ln\u00edm materi\u00e1lem pro v\u00fdstavbu modern\u00edch pasivn\u00edch a n\u00edzkoenergetick\u00fdch dom\u016f je d\u0159evo.

Abyste do d\u0159evostavby zajistili p\u0159\u00edvod \u010derstv\u00e9ho vzduchu a z\u00e1rove\u0148 zabr\u00e1nili ztr\u00e1t\u00e1m tepla, je nutno pou\u017e\u00edt rekuperaci vzduchu.

D\u00edky tomu se udr\u017euje st\u00e1l\u00e1 teplota v cel\u00e9m dom\u011b.<\/p>\n\n\n\n

Bez st\u00edn\u011bn\u00ed se v pasivn\u00ed d\u0159evostavb\u011b neobejdete

Zat\u00edmco v zim\u011b je slunce jako zdroj tepla v\u00edt\u00e1no, v l\u00e9t\u011b se pasivn\u00ed a n\u00edzkoenergetick\u00e9 d\u0159evostavby neobejdou bez st\u00edn\u011bn\u00ed oken, aby nedoch\u00e1zelo k p\u0159eh\u0159\u00edv\u00e1n\u00ed interi\u00e9ru.

Pro pasivn\u00ed d\u0159evostavbu volte vn\u011bj\u0161\u00ed rolety
N\u00edzkoenergetick\u00e9 d\u0159evostavby maj\u00ed sice dobr\u00e9 tepeln\u011bizola\u010dn\u00ed vlastnosti, ale aby v\u00e1\u0161 d\u016fm dosahoval pasivn\u00edho standardu, vyplat\u00ed se po\u0159\u00eddit si vn\u011bj\u0161\u00ed zatem\u0148uj\u00edc\u00ed rolety.
