Qu\u00e8 \u00e9s la Calefacci\u00f3 de baix consum?<\/strong><\/p>\n

quin sistema de calefacci\u00f3 instal\u00b7lar en una casa passiva?<\/strong><\/p>\n

quant costa?<\/strong><\/p>\n

Aqu\u00ed us mostrem les bases dels sistemes de calefacci\u00f3 de baix consum per a casa molt eficient i casa passiva.
\nPer si encara no ens coneixes, ens presentem molt breument.
\nSom ERA architects, un dels joves i creatius\u00a0estudis d’Arquitectura a Barcelona.<\/p>\n

 <\/p>\n

Qu\u00e8 \u00e9s la Calefacci\u00f3 de baix consum?<\/strong>
\nCalefacci\u00f3 \u00e9s el conjunt daparells que formen un sistema i serveixen per escalfar un lloc.
\nEn el cas de casa de consum gaireb\u00e9 nul o casa passiva, la demanda en calefacci\u00f3 ha de ser igual o menor a 15 kWh\/m2a.
\nAix\u00f2 vol dir que lenergia que escalfa la casa ha de ser similar a la dun ventilador de p\u00e8l.<\/p>\n

 <\/p>\n

Calefacci\u00f3 de baix consum i casa eficient o casa passiva
\nAix\u00f2 nom\u00e9s \u00e9s possible si l’edificaci\u00f3 t\u00e9 una bona capa d’a\u00efllament, si est\u00e0 ben segellada i no t\u00e9 ponts t\u00e8rmics.
\n\u00c9s a dir que la construcci\u00f3 no deixi escapar la calor que es genera a dins.
\nAquest tipus d’edificaci\u00f3 es defineix com a construcci\u00f3 passiva.<\/p>\n

 <\/p>\n

Sistemes de calefacci\u00f3 de baix consum
\nAtenci\u00f3 en aquest post t’explico sistemes de calefacci\u00f3 de baix consum per a cases passives amb la demanda energ\u00e8tica m\u00e0xima en calefacci\u00f3 de 15kwh\/m2a.
\nAquesta \u00e9s la nostra llista de sistemes de calefacci\u00f3 de baix consum des del m\u00e9s econ\u00f2mic al m\u00e9s car.<\/p>\n

Resist\u00e8ncia el\u00e8ctrica
\n\u00c9s una resist\u00e8ncia el\u00e8ctrica connectada a la impulsi\u00f3 de la ventilaci\u00f3 mec\u00e0nica controlada.
\n\u00c9s una opci\u00f3 l\u00f2gica, senzilla i econ\u00f2mica per a la casa passiva (tamb\u00e9 la m\u00e9s semblant a un escalfador de p\u00e8l;)
\nLa resist\u00e8ncia el\u00e8ctrica escalfa l\u02bbaire abans d\u02bbimpulsar-lo al\u02bbinterior de la casa passiva.<\/p>\n

Caldera de condensaci\u00f3 (gas o gasoil)
\nL?opci\u00f3 m\u00e9s estesa a Espanya.
\nCombina escalfament daigua i calefacci\u00f3.
\nLa normativa espanyola exigeix \u200b\u200bla ventilaci\u00f3 de la caldera per una reixeta i aix\u00f2 pot ser un problema per a la casa passiva ja que necessita estar completament segellada.
\nTamb\u00e9 estem lligats al preu del gas, per tant, \u00e9s una opci\u00f3 incerta a llarg termini.<\/p>\n

Bomba de calor o Aerot\u00e8rmia
\nMolt recomanable per a climes freds en hivernacle i calorosos a l’estiu (doncs pot impulsar aire fred tamb\u00e9).<\/p>\n

Biomassa
\nIdeal per a climes freds i de muntanya amb estius frescos.
\nPer a casa passiva \u00e9s molt important escollir una m\u00e0quina certificada, ja que la casa passiva necessita tenir un bon segellat i ser herm\u00e8tica amb l’exterior.
\nLa xemeneia connecta amb l’exterior i no deixa de ser un punt feble a la casa passiva.<\/p>\n

M\u00e0quina compacta o Aerot\u00e8rmia amb ACS
\nSens dubte, una gran opci\u00f3 ja que inclou la ventilaci\u00f3 mec\u00e0nica controlada de doble flux i el sistema d’escalfament de l’aigua.
\nEl seu desavantatge \u00e9s l’elevat cost i les grans dimensions que obliguen a tenir una bona cambra d’instal\u00b7lacions a\u00efllada ac\u00fasticament.<\/p>\n

Geot\u00e8rmia
\nLa m\u00e9s ecol\u00f2gica i la m\u00e9s cara de totes les opcions.
\nAquesta opci\u00f3 combina la bomba de calor amb conductes subterranis per prendre la temperatura sota terra que \u00e9s fresca a l’estiu i calenta a l’hivern.
\nGran part dels clients que v\u00e9nen amb aquesta idea acaben desestimant-la.<\/p>\n

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

Al nostre\u00a0estudi d’Arquitectura a Barcelona, \u200b\u200brecomanem fer cases eficients de consum gaireb\u00e9 nul amb un sistema de ventilaci\u00f3 mec\u00e0nica controlada de doble flux amb una resist\u00e8ncia el\u00e8ctrica connectada a fonts renovables seguint els criteris de les cases passives definits pel Passive House Institute.<\/p>\n

 <\/p>\n

Espero que aquesta info t’ajudi en la teva\u00a0aventura.
\nFins al proper post!<\/p>\n
