Evidentment que podr\u00e0s fer-ho! Ja sabem que les cases passives disposen d’una hermeticitat molt elevada per a evitar infiltracions d’aire no desitjades que provoquin p\u00e8rdues d’energia en l’habitatge i alhora disminueixin la qualitat de l’aire interior i el seu confort.<\/p>\n

D’aquesta manera no tindria sentit ventilar la casa obrint les finestres, acci\u00f3, dit sigui de passada, amb la qual igualment no aconseguir\u00edem a una ventilaci\u00f3 adequada i eficient de tot l’habitatge. Per evitar aquesta situaci\u00f3 un habitatge “Passivhaus” est\u00e0 dotat d’un sistema de ventilaci\u00f3 mec\u00e0nica de doble flux amb recuperador de calor que permet una renovaci\u00f3 constant de l’aire interior a partir de la recirculaci\u00f3 de l’aire fresc filtrat i captat des de l’exterior i l’expulsi\u00f3 de l’aire viciat de l’interior.
\nAl seu torn aquest sistema de ventilaci\u00f3<\/a> contribueix a l’estalvi energ\u00e8tic de les cases passives ja que actua com un intercanviador extraient fins al 90% de l’energia de l’aire sortint per prestar-a l’aire entrant, d’aquesta manera a l’hivern l’aire de l’exterior s’escalfa abans de distribuir-se per les estances, i a l’estiu, de forma inversa, es refresca .<\/p>\n

Quan no has viscut en una casa passiva i procedeixes d’una cultura mediterr\u00e0nia aquesta informaci\u00f3 acostuma a ser xocant ja que contradiu els nostres usos i costums per\u00f2 la realitat \u00e9s ben diferent.<\/p>\n

En una casa passiva podem obrir les finestres i \/ o gaudir de la porxada i el jard\u00ed amb la nostra fam\u00edlia i amics sense cap problema, el que passa \u00e9s que amb l’\u00fas continuat comprovarem que no cal obrir les finestres per ventilar ja que gaudirem de m\u00e9s confort (i estalvi energ\u00e8tic) si no ho fem i en cas que ho fem \u00fanicament estarem incrementat la demanda energ\u00e8tica de l’habitatge i per tant la seva despesa tot i que aquesta sempre ser\u00e0 molt menor que la d’un habitatge convencional amb sistemes de ventilaci\u00f3 tradicionals.<\/p>\n","protected":false},"excerpt":{"rendered":"
