Com es pot reformar perqu\u00e8 el teu pis sigui una Casa Passiva?<\/strong><\/p>\n

En aquest post ‘Reforma Casa Passiva Barcelona’, t’explico les diferents opcions per reformar el teu pis en clima c\u00e0lid-temperat i tenir una llar Passive House.<\/span><\/p>\n

En dir, t’explico les 5 claus per transformar el teu pis en una Casa Passiva (o gaireb\u00e9).<\/span><\/p>\n

Per si encara no ens coneixes, em presento, s\u00f3c Esther Rovira, fundadora d’ERA architects, arquitecta a Barcelona<\/a> i passive house designer per a reformes sostenibles, reformes passives, cases passives, cases eficients i cases positives a Barcelona i Catalunya.<\/span><\/p>\n

Espero que t’ajudi!<\/span><\/p>\n

 <\/p>\n

 <\/p>\n

1) Mai ser\u00e0 una Casa Passiva<\/strong><\/p>\n

El Passive House Institute especifica que una reforma d’una part d’un edifici existent mai no ser\u00e0 una casa passiva.<\/span><\/p>\n

Aix\u00f2 \u00e9s degut a que no en tots els casos podrem complir els par\u00e0metres estrictes de l’institut alemany.<\/span><\/p>\n

El Passive House tampoc no permet certificar una part d’un edifici.<\/span><\/p>\n

Aix\u00f2 vol dir que la reforma del teu apartament sense una intervenci\u00f3 integral de tots els ve\u00efns no es pot certificar.<\/span><\/p>\n

 <\/p>\n

Cal entendre que els est\u00e0ndards del Passive House s\u00f3n unes regles definides per arquitecte-enginyers alemanys que a priori es basen en el context m\u00e9s proper (Alemanya).<\/span><\/p>\n

Per aix\u00f2, en altres contextos com Barcelona amb altres premisses de clima, humitat; per\u00f2 tamb\u00e9 de tipologia d’edificis i economicosocials, potser \u00e9s m\u00e9s dificult\u00f3s aplicar una certificaci\u00f3.<\/span><\/p>\n

Tot i aix\u00ed, sens dubte \u00e9s l’est\u00e0ndard m\u00e9s preparat per fer front als reptes futurs de la neutralitat clim\u00e0tica del 2050 i moderar el consum d’energia a les llars.<\/span><\/p>\n

 <\/p>\n

2) A\u00efllar per dins<\/strong><\/p>\n

El m\u00e9s eficient per a una reforma passive \u00e9s a\u00efllar per fora, per la fa\u00e7ana.<\/span><\/p>\n

Per\u00f2 si no vols entrar a un projecte integral amb la teva comunitat de ve\u00efns, el millor \u00e9s a\u00efllar per dins (m\u00e9s r\u00e0pid, m\u00e9s barat, menys problemes).<\/span><\/p>\n

Depenent del Solejament i orientaci\u00f3 a Barcelona solen sortir entre 6-10cm d’a\u00efllament a la fa\u00e7ana.<\/span><\/p>\n

No est\u00e0 a faltar a\u00efllar el terra entre 5-10cm (segons el tipus d’a\u00efllant o si est\u00e0s en un primer o un 4t pis).<\/span><\/p>\n

Si est\u00e0s sota la coberta de l’edifci haur\u00e0s d’aplicar a\u00efllant tamb\u00e9 al teu sostre entre 15 i 20 cm (segons orientaci\u00f3 i sistema constructiu de la coberta).<\/span><\/p>\n

Per poder escollir el gruix d’a\u00efllant i material m\u00e9s eficient, el millor \u00e9s que un Arquitecte\/a Pasive House Designer us ho calculi fent una simulaci\u00f3 Passive.<\/span><\/p>\n

 <\/p>\n

3) Finestres<\/strong><\/p>\n

Per a una reforma sostenible, eficient i passiva, heu de canviar totes les finestres.<\/span><\/p>\n

La ra\u00f3 \u00e9s que les finestres antigues solen ser la font principal de pont t\u00e8rmic, filtracions, captaci\u00f3 i protecci\u00f3 solar.<\/span><\/p>\n

Depenent d’orientaci\u00f3 i assolellament, podries instal\u00b7lar unes finestres amb una sola c\u00e0mera amb vidre sota emissiu-passiu amb gas Argon (caldria calcular els vidres i transmet\u00e0ncia de la fusteria a trav\u00e9s d’una simulaci\u00f3 Passive).<\/span><\/p>\n

Com potser ja saps, a Barcelona no pots canviar les finestres sense una estrat\u00e8gia conjunta amb els teus ve\u00efns.<\/span><\/p>\n

Tot i que segurament alguns ve\u00efns ja les han canviat sense consultar ning\u00fa\u2026<\/span><\/p>\n

Aix\u00ed que no s\u00e9 ben b\u00e9 qu\u00e8 dir-te sobre aquest tema (sembla que est\u00e0s obligat\/da a quedar amb els teus ve\u00efns).<\/span><\/p>\n

 <\/p>\n

4) Hermeticitat<\/strong><\/p>\n

Per evitar les filtracions de la climatitzaci\u00f3 interior del teu habitatge \u00e9s b\u00e0sic i necessari que sigui herm\u00e8tica.<\/span><\/p>\n

Per aix\u00f2 pots aplicar una capa de guix a totes les superf\u00edcies.<\/span><\/p>\n

Com que segurament ja tens una capa de guix a parets, en pots aplicar una altra al sostre i tros de parets sota el fals sostre.<\/span><\/p>\n

Tamb\u00e9 has d’aplicar a totes les trobades un producte que asseguri l’hermeticitat.<\/span><\/p>\n

Per trobades em refereixo a terra-paret, paret-sostre i paret-finestra.<\/span><\/p>\n

 <\/p>\n

5) VMC amb recuperador + AC<\/strong><\/p>\n

Instal\u00b7lant un sistema de Ventilaci\u00f3 Mec\u00e0nica Controlada de doble flux amb recuperador de calor i bypass per a estiu; estalvies en calefacci\u00f3.<\/span><\/p>\n

Aquest sistema \u00e9s impepinable perqu\u00e8 el teu habitatge tingui un nivell de salut i confort.<\/span><\/p>\n

Sense VMC el teu habitatge tindr\u00e0 un aire viciat on virus com el Covid s’ho passaran d’all\u00f2 m\u00e9s b\u00e9.<\/span><\/p>\n

Per refrigerar a l’estiu, cal instal\u00b7lar tamb\u00e9 1-2 aparells d’aire condicionat.<\/span><\/p>\n

Com que el teu habitatge \u00e9s altament a\u00efllat i herm\u00e8tic, l’aire ho encendres en mode silenci i estalvi durnat m\u00e0xim 2-3hr al dia (igual si ets Ice Men alguna cosa m\u00e9s, ja saps, el confort pot ser subjectiu).<\/span><\/p>\n

 <\/p>\n

\u00a0<\/span><\/p>\n

 <\/p>\n

La meva recomanaci\u00f3 professional:<\/strong><\/p>\n

Al nostre estudi d’Arquitectura a Barcelona calculem els a\u00efllants i m\u00e0quines fent una simulaci\u00f3 amb el nostre programari per a Passive House.<\/span><\/p>\n

Sin\u00f3 tens diners per a tot, et recomano que facis aquelles coses que no puguis fer m\u00e9s endavant com: guix al sostre, l\u00ednia herm\u00e8tica en trobades i previsi\u00f3 de VMC (a partir de 700\u20ac+iva).<\/span><\/p>\n

La resta i segons la configuraci\u00f3 d’habitatge podr\u00e0s fer-ho m\u00e9s endavant.<\/span><\/p>\n
