Busques cases eficients?<\/p>\n

Vols estalviar en calefacci\u00f3 i refrigeraci\u00f3?<\/p>\n

No saps per on comen\u00e7ar?<\/p>\n

 <\/p>\n

En aquest post t’expliquem les nocions b\u00e0siques en disseny, l’arquitectura i construcci\u00f3 de les cases eficients.
\nPer si encara no ens coneixes, permet-nos presentar-nos.
\nSom l’estudi d’Arquitectura a Barcelona ERA arquitectes<\/a>\u00a0i recomanem fer cases eficients a tots els nostres clients.
\nEn aquest post pots trobar les nostres recomanacions professionals per fer una casa eficient.<\/p>\n

 <\/p>\n

UBICACI\u00d3<\/p>\n

    \n
  1. Situa la teva casa de forma que el sol entri a l’interior a l’hivern<\/li>\n
  2. Considera la geografia, topografia i ombres del solar (muntanyes, arbres i edificis) i vent al situar la casa en el lloc<\/li>\n
  3. Utilitza elements del paisatge com a refugi a l’hivern i refredament a l’estiu (arbres, parets de jardins, estanys i \/ o piscina)<\/li>\n<\/ol>\n

     <\/p>\n

    FORMA I DISSENY<\/p>\n

      \n
    1. L’orientaci\u00f3 i el clima s\u00f3n crucials<\/li>\n
    2. Apr\u00e8n dels vilatans (inspira’t en la saviesa de l’arquitectura local)<\/li>\n
    3. Fa\u00e7ana principal orientada al Sud o al Sud-est (per capturar el sol a l’hivern. Tamb\u00e9 s’evita el Sol ponent a l’oest en climes c\u00e0lids doncs a l’estiu pot ser matador)<\/li>\n
    4. Evita que el Sol del Sud entre a l’estiu (la p\u00e8rgola \u00e9s una molt bona opci\u00f3)<\/li>\n
    5. Aprofita el comportament del Sol i del vent per escalfar i refrescar la teva casa<\/li>\n
    6. Situa les habitacions fredes al Nord (bany, cuina, entrada, passad\u00eds)<\/li>\n
    7. Considera un disseny de casa de volum compacte doncs consumeix menys energia<\/li>\n<\/ol>\n

       <\/p>\n

      ENVOLVENT (4 parets, sostre i terra)<\/p>\n

        \n
      1. Tingues en compte les propietats naturals de cada material (formig\u00f3 i cer\u00e0mica tenen un alt emmagatzematge t\u00e8rmic per\u00f2 baixa capacitat d’a\u00efllament, mentre que la fusta massissa t\u00e9 un l’emmagatzematge t\u00e8rmic i alts valors d’a\u00efllament)<\/li>\n
      2. El confort ambiental dep\u00e8n del que s’est\u00e0 fent i utilitzant (no \u00e9s el mateix adequar el clima interior en un espai on hi ha 4 persones jugant a Just Dance a la wii amb els llums encesos d’adequar el mateix espai amb una persona llegint amb llum natural)<\/li>\n
      3. Embolica l’edifici de forma cont\u00ednua en tots els costats (inclosa al terra de la planta baixa)<\/li>\n
      4. Es recomana usar finestres amb dues c\u00e0meres i triple vidre (les finestres de doble vidre tenen 6 vegades menys valors d’a\u00efllament que una paret a\u00efllada adequada)<\/li>\n
      5. Considera una casa semi soterrada o amb sostres verds per protegir contra la p\u00e8rdua de calor<\/li>\n<\/ol>\n

         <\/p>\n

        ENERGIA I INTERIOR DEL MEDI AMBIENT<\/p>\n

          \n
        1. Combina el guany solar amb la massa t\u00e8rmica (massa t\u00e8rmica \u00e9s la capacitat de retenir la calor) (finestra de 2-4% de l’\u00e0rea total de l’edifici)<\/li>\n
        2. Captura la calor amb un hivernacle del sud<\/li>\n
        3. Utilitza la din\u00e0mica t\u00e8rmica (l’aire calent puja) (l’aire calent vol ser fred)<\/li>\n
        4. Considea utilitzar una paret t\u00e8rmica (paret de 30-40cm orientada al Sol per absorbir la calor a l’hivern) (capacitats d’emmagatzematge t\u00e8rmic -> formig\u00f3: 3, terra: 11, aigua: 12)<\/li>\n
        5. Considera tenir un estany al sostre (la calor s’allibera lentament)<\/li>\n
        6. Considera sistemes geot\u00e8rmics (capta la calor que ret\u00e9 la terra i refresca l’ambient amb conductes subterranis)<\/li>\n
        7. Considera la possibilitat de recuperar la calor amb sistemes de doble flux<\/li>\n
        8. Usa ventilaci\u00f3 creuada<\/li>\n
        9. Fes servir la llum del dia per reduir l’electricitat (cada habitaci\u00f3 amb llum natural) (finestra = 20% de la superf\u00edcie de la paret) (les finestres altes capturen m\u00e9s llum)<\/li>\n
        10. Simplifica i considera sistemes dom\u00f2tics perqu\u00e8 l’edifici s’adapti autom\u00e0ticament als canvis clim\u00e0tics<\/li>\n<\/ol>\n
