Com a\u00efllar una Casa Positiva?<\/span><\/p>\n

Com saber l’espessor de l’a\u00efllament a la meva Casa Positiva?<\/span><\/p>\n

\n

Si encara no ens coneixeu: som ERA arquitectes.<\/span>
\nEn realitat s\u00f3c Esther Rovira, arquitecta i Passive House designer a Barcelona, \u200b\u200bCatalunya i Andorra de cases passives, cases eficients i cases positives.<\/span>
\nEn aquest post \u2018A\u00efllament en una casa positiva\u2019<\/em>, trobar\u00e0s la nostra recomanaci\u00f3 professional.<\/span>
\nEspero que t’ajudi. Som-hi!<\/span><\/p>\n<\/div>\n

 <\/p>\n

L’a\u00efllament \u00e9s el segon element imprescindible d’una casa positiva.<\/span>
\nSi t’has saltat el primer, consulta el nostre post<\/span>: ‘Volum compacte d’una casa positiva’<\/a><\/span><\/em><\/p>\n

 <\/p>\n

\u00a0Qu\u00e8 vol dir a\u00efllament?<\/strong><\/p>\n

A\u00efllar significa protegir casa teva del clima col\u00b7locant un material envoltant per evitar la p\u00e8rdua de calor i fred (tamb\u00e9 ajuda a evitar la intrusi\u00f3 de so).<\/span><\/p>\n

Definicions a part, significa posar una manta embolicant casa teva.
\n<\/span>\u00c9s com el que fas a l’hivern quan veus una pel\u00b7l\u00edcula: fas servir una manta perqu\u00e8 no se’n vagi la calor.<\/span><\/p>\n

I pensar\u00e0s, com funciona aix\u00f2 a l’estiu? Mai no utilitzaria una manta a l’estiu?
\n<\/span>Doncs b\u00e9, tu ets un \u00e9sser hum\u00e0 i produeixes calor de forma natural, mentre que casa teva \u00e9s una cosa i no produeix calor de forma natural.
\nB\u00e9, t\u00e8cnicament casa teva produir\u00e0 calor si fas una “pizza party”<\/em>. D’aquesta manera, el forn estar\u00e0 produint calor i la fam\u00edlia i els amics tamb\u00e9 produiran calor (aix\u00ed que si \u00e9s estiu, estar\u00e0s m\u00e9s a gust fent una festa d’amanides a l’aire lliure al costat de la piscina).\u00a0<\/span><\/p>\n

Bromes a part, casa teva pot produir calor o fred utilitzant els sistemes de climatitzaci\u00f3.
\n<\/span>Aix\u00f2 significa que si vols fer-te una migdiada despr\u00e9s de dinar en un dia d’estiu de calor abrasadora (35\u00baC), el m\u00e9s probable \u00e9s que optis per fer-te-la dins amb l’aire condicionat. Aleshores, en una casa positiva, utilitzar\u00e0s el sistema de refrigeraci\u00f3 durant 10 minuts per refredar la teva habitaci\u00f3 durant la resta de la tarda. (Recordeu-vos d’usar el despertador per a aquesta bona migdiada!)\u00a0<\/span><\/p>\n

Aix\u00ed que, b\u00e0sicament, l’a\u00efllament mant\u00e9 la calor i la refrigeraci\u00f3 a l’interior durant m\u00e9s temps de qu\u00e8 estem acostumats. Aix\u00f2 significa menys consum d’energia.<\/span><\/p>\n

 <\/p>\n

Per tant, hi ha 3 coses que cal tenir en compte sobre l’a\u00efllament<\/span>:<\/p>\n

 <\/p>\n

1) Calcular l’a\u00efllament<\/b>\u00a0<\/strong><\/p>\n

En primer lloc, cal calcular l’a\u00efllament fent servir el simulador de cases passives.<\/span><\/p>\n

El simulador et d\u00f3na el gruix d’a\u00efllament espec\u00edfic per a la teulada, fa\u00e7ana i forjat de casa teva. I t\u00e9 en compte tots els par\u00e0metres de casa teva (per a m\u00e9s detalls sobre els par\u00e0metres que utilitza el simulador de casa positiva, consulta<\/span>\u00a0’10 claus per una casa positiva’<\/a><\/span><\/span>.
\nHas de saber que la majoria dels arquitectes no tenen els coneixements necessaris per fer-ho. Aix\u00ed que contractaran una altra persona perqu\u00e8 ho faci. Aix\u00f2 podria significar serveis m\u00e9s cars, per\u00f2 encara pitjor, perdre informaci\u00f3 amb els m\u00faltiples agents amb pocs coneixements espec\u00edfics. Et recomano que consideris un arquitecte que tamb\u00e9 sigui dissenyador de cases passives.<\/span><\/p>\n

2) Dibuixar A\u00efllament segons c\u00e0lcul<\/b><\/strong><\/p>\n

En segon lloc, l’arquitecte ha de dibuixar una vista de tall lateral detallada.
\nAqu\u00ed podr\u00edeu comprovar el gruix de cada pe\u00e7a d’a\u00efllament de la teulada, la fa\u00e7ana i el forjat.
\nAquest dibuix ha d’estar a escala i els gruixos han de coincidir amb els valors de la simulaci\u00f3 passiva per poder certificar casa positiva.<\/span><\/p>\n

3)\u00a0 A\u00efllament continu<\/b><\/strong><\/p>\n

Per acabar, l’a\u00efllament ha de ser continu i envoltar tota la casa.
\nAix\u00f2 vol dir que l’a\u00efllament del forjat ha de connectar amb l’a\u00efllament de la fa\u00e7ana sense que res hi irrompi.
\nEl mateix passa amb la connexi\u00f3 fa\u00e7ana-sostre: l’a\u00efllament ha de ser continu. Sense trencaments.
\n<\/span>Si hi ha trencaments, cal calcular-los com el que anomenem: ponts t\u00e8rmics. A continuaci\u00f3, introdueix-los al simulador passiu per comprovar els efectes d’aquesta fuita de confort a casa teva.<\/span><\/p>\n

 <\/p>\n

La nostra recomanaci\u00f3 professional:
\n<\/strong>Demana al teu arquitecte que t’entregui un tall de secci\u00f3 amb els gruixos d’a\u00efllament amb dimensions ia escala abans que comenci la construcci\u00f3<\/span>.
\nSi no \u00e9s capa\u00e7 de lliurar-ho, \u00e9s que no ha pensat en totes les trobades i aix\u00f2 segurament provocar\u00e0 alguns ponts t\u00e8rmics i casa teva no ser\u00e0 100% eficient.<\/span>.<\/p>\n
