Comparativa BREEAM, Leed i Passive House<\/span><\/p>\n

 <\/p>\n

Quines finestres instal\u00b7lar per a la teva Casa Passiva?<\/strong><\/p>\n

En aquest post \u2018Comparativa BREEAM, Leed i Passive House\u2019, t’explico les difer\u00e8ncies entre aquests 3 certificats per a edificis sostenibles.<\/span><\/p>\n

\u00c9s a dir, t’explico els pros i els contres perqu\u00e8 escullis el millor per a la teva casa sostenible.<\/span><\/p>\n

 <\/p>\n

Per si encara no ens coneixes, em presento, s\u00f3c l’Esther Rovira, fundadora d’ERA architects, arquitecta a Barcelona 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

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

 <\/p>\n

1) BREEAM<\/strong><\/p>\n

El certificat Breeam prov\u00e9 d’Anglaterra i \u00e9s el m\u00e9s antic (anys 90).<\/span><\/p>\n

Per tant, \u00e9s el que t\u00e9 m\u00e9s extensi\u00f3 global i compta amb m\u00e9s edificis amb el seu segell (a Espanya compta amb 725 associats).<\/span><\/p>\n

Consisteix a analitzar els impactes de les fases de disseny, construcci\u00f3 i \u00fas dels edificis.<\/span><\/p>\n

 <\/p>\n

PROS<\/span><\/p>\n

Aix\u00f2 s’aconsegueix comptabilitzant 10 aspectes: gesti\u00f3, millora de la salut i benestar, efici\u00e8ncia energ\u00e8tica, transport, aigua (estalvi), \u00fas de materials, residus (gesti\u00f3), \u00fas del s\u00f2l, innovaci\u00f3 i contaminaci\u00f3.<\/span><\/p>\n

 <\/p>\n

CONS<\/span><\/p>\n

No \u00e9s el m\u00e9s matem\u00e0tic, ja que d\u00f3na una puntuaci\u00f3 final que t\u00e9 en compte aspectes molt diversos.<\/span><\/p>\n

Aix\u00f2 ha donat casos d’edificis sense massa efici\u00e8ncia energ\u00e8tica que han donat un valor bo final en combinar elements exteriors com ara p\u00e0rquing de bicicletes o enjardinament exterior amb plantes aut\u00f2ctones.<\/span><\/p>\n

Diguem que d\u00f3na un valor general de l’edifici i el seu entorn, per\u00f2 no se centra que l’edifici tingui un cosum molt baix.<\/span><\/p>\n

 <\/p>\n

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

 <\/p>\n

2) LEED<\/strong><\/p>\n

Aquest certificat Americ\u00e0 (tamb\u00e9 dels anys 90) est\u00e0 molt ben valorat globalment.<\/span><\/p>\n

Avalua 5 aspectes principals: empla\u00e7ament, efici\u00e8ncia energ\u00e8tica i aigua, energia renovable, \u00fas de mat\u00e8ries i recursos naturals i aire interior.<\/span><\/p>\n

 <\/p>\n

PROS<\/span><\/p>\n

\u00c9s molt flexible per tres raons: s’aplica a obra nou o reforma, sector habitatge o equipaments i disposa de 3 nivells de certificaci\u00f3 (gold, silver, platinium).<\/span><\/p>\n

Podeu arribar a garantir estalvis energ\u00e8tics de fins al 60%.<\/span><\/p>\n

S’utilitza molt a edificis d’oficines (el 2020, el 63% dels edificis certificats LEED a Espanya van ser oficines).<\/span><\/p>\n

 <\/p>\n

CONS<\/span><\/p>\n

El 2020 tot i registrar-se 910 edifcis, se’n van certificar aproximadament la meitat (la majoria a Madrid i Barcelona).<\/span><\/p>\n

 <\/p>\n

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

 <\/p>\n

3) Passive House<\/strong><\/p>\n

Aquest est\u00e0ndard Europeu fundat el 1996 per un f\u00edsic Alemany, se centra a definir els valors m\u00e0xims a complir per un edifici molt eficient.<\/span><\/p>\n

Aquests valors defineixen els nivells m\u00e0xims de: consum d’energia en climatitzaci\u00f3 (calefacci\u00f3 i refrigeraci\u00f3), energia prim\u00e0ria (comptabilitza quant consumir\u00e0 la casa comptant electrodom\u00e8stics, il\u00b7luminaci\u00f3 i m\u00e0quines), hermeticitat (abs\u00e8ncia de filtracions) i renovacions d’aire (aire renovat cada 20 minuts).<\/span><\/p>\n

Tot aix\u00f2 es resumeix a aplicar un disseny i construcci\u00f3 de l’edifici herm\u00e8tic, amb un bon a\u00efllament, sense ponts t\u00e8rmics i amb ventilaci\u00f3 mec\u00e0nica controlada de doble flux amb recuperador de calor (i si vols amb membrana ent\u00e0lpica per retenir els virus).<\/span><\/p>\n

A Espanya hi ha gaireb\u00e9 896 associats a aquest est\u00e0ndard alemany (octubre 2021).<\/span><\/p>\n

 <\/p>\n

PROS<\/span><\/p>\n

Gr\u00e0cies a aquests punts claus; s’aconsegueix fins a un 80% d’estalvi energ\u00e8tic en comparaci\u00f3 de l’edificaci\u00f3 convencional.<\/span><\/p>\n

\u00c9s sens dubte la certificaci\u00f3 m\u00e9s exigent i complexa que asegura un m\u00e0xim estalvi en el consum d’energia.<\/span><\/p>\n

\u00c9s aparentment flexible poden aplicar-se en obra nova i reforma, habitatges i sector terciari (per\u00f2 en realitat la seva super-calculadora-simulador \u00e9s molt complexa en les seves variants) i tenint 3 nivells (Classic, Plus, Premium).<\/span><\/p>\n

 <\/p>\n

CONS<\/span><\/p>\n

L’\u00fanica pega d’aquesta certificaci\u00f3 \u00e9s que no t\u00e9 en compte l’\u00fas de materials naturals ni la gesti\u00f3 de l’aigua.<\/span><\/p>\n

 <\/p>\n

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

 <\/p>\n

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

Hi ha altres segells de qualitat en edificis energ\u00e8tics que no valorem en aquest post.<\/span><\/p>\n

Com ara el VERD, el NetZero Energy Building certification, el su\u00eds Minergie i el WELL entre d’altres.<\/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 recomanem el certificat Passive House per a habitatges.<\/span><\/p>\n

La ra\u00f3 \u00e9s que \u00e9s el m\u00e9s exigent i assegura un gran estalvi energ\u00e8tic durant l’\u00fas de l\u2019edifici.<\/span><\/p>\n

Per no doblar esfor\u00e7os (i honoraris de servei), et recomano que busquis un arquitecte que:<\/span><\/p>\n

\u2013 sigui Passive House designer<\/span><\/p>\n

\u2013 hagi certificat algun habitatge a l’\u00faltim any<\/span><\/p>\n

– tingueu contacte amb m\u00e9s d’una entitat certificadora (no hi ha molta varietat de certificadors a Espanya i s\u00f3n cars)<\/span><\/p>\n

 <\/p>\n

Potser tamb\u00e9 t’interessi:<\/strong><\/p>\n

El nostre altre post: Casa Passiva Classic, Plus o Premium<\/span><\/p>\n

O saber que si et subscrius al nostre butllet\u00ed de recomanacions per a casa teva passiva o casa positiva; rebr\u00e0s informaci\u00f3 \u00fatil i podr\u00e0s optar a descomptes als nostres serveis.<\/span><\/p>\n

I per descomptat et pots donar de baixa quan vulguis!<\/span><\/p>\n

(aviat traurem nous post sobre altres tipus de certificaci\u00f3)<\/span><\/p>\n

Espero que aquest post ‘Comparativa BREEAM, Leed i Passive House’ t’ajudi.
