Els sistemes de calefacci\u00f3 t\u00edpics a Europa consisteixen normalment en un sistema d\u2019escalfament d\u2019aigua centralitzat amb radiadors, canonades i escalfadors per\u00f2, i si no hagu\u00e9s de ser aix\u00ed? Aquesta \u00e9s la idea de les cases passives; passive House en angl\u00e8s o passivhaus en alemany, d\u2019on prov\u00e9 el terme originalment.<\/span><\/p>\n

Qu\u00e8 \u00e9s Passivhaus<\/span><\/h2>\n

El concepte de l\u2019arquitectura passiva (Passive House) neix de la idea de qu\u00e8, probablement, la despesa energ\u00e8tica i econ\u00f2mica destinades a sistemes de calefacci\u00f3 i aire condicionat s\u00f3n innecessaris<\/strong>.<\/span><\/p>\n

Es basa en la construcci\u00f3 de cases de baix consum energ\u00e8tic mitjan\u00e7ant, b\u00e0sicament, la minimitzaci\u00f3 de les p\u00e8rdues de calor al m\u00ednim de manera que s\u2019aconsegueixi una sensaci\u00f3 t\u00e8rmica agradable i constant independentment de l\u2019\u00e8poca de l\u2019any.<\/span><\/p>\n

Caracter\u00edstiques d\u2019una Passivhaus<\/span><\/h2>\n

Perqu\u00e8 se la consideri Passive House, existeixen una s\u00e8rie de caracter\u00edstiques. Aquestes son les que aconsegueixen aquest confort t\u00e8rmic constant<\/strong> del que parl\u00e0vem:<\/span><\/p>\n

Reducci\u00f3 de p\u00e8rdues de calor<\/strong><\/span><\/h3>\n

A la majoria de les cases existeixen fugues d\u2019aire a portes, finestres, escletxes… amb un bon a\u00efllament es poden evitar aquestes filtracions<\/strong> que comporten p\u00e8rdues t\u00e8rmiques continues. Una Passive House ha de passar amb nota una prova d\u2019impermeabilitat\u00a0 d\u2019aire. A m\u00e9s de tenir el millor segellat i a\u00efllament, aquest m\u00e8tode ajuda a evitar l\u2019aparici\u00f3 de floridura o fongs<\/strong>, t\u00edpics dels llocs humits.<\/span><\/p>\n

A\u00efllament t\u00e8rmic<\/strong><\/span><\/h3>\n

El punt anterior no \u00e9s la \u00fanica manera que t\u00e9 l\u2019escalfor per escapar. A m\u00e9s, parets i sostres poden contribuir-hi, aix\u00ed que a una casa passiva ser\u00e0 important un \u00f2ptim a\u00efllament t\u00e8rmic<\/strong>. D\u2019acord amb el clima en qu\u00e8 es construeixi, els materials hauran de comptar amb unes caracter\u00edstiques o altres per a arribar als est\u00e0ndards requerits.<\/span><\/p>\n

Eliminaci\u00f3 de ponts t\u00e8rmics<\/strong><\/span><\/h3>\n

Es considera pont t\u00e8rmic al recorregut que efectua l\u2019escalfor des del punt en qu\u00e8 es produeix fins el que s\u2019aprofita. La eliminaci\u00f3 d\u2019aquestes \u201cautopistes\u201d en qu\u00e8 l\u2019escalfor s\u2019escapa \u00e9s fonamental i s\u2019efectua mitjan\u00e7ant, per exemple, parets dobles o l\u2019a\u00efllament dels fonaments<\/strong>.<\/span><\/p>\n

Especial atenci\u00f3 a portes i finestres<\/strong><\/span><\/h3>\n

Ambdues estructures demanen un alt rendiment t\u00e8rmic aix\u00ed com la millor localitzaci\u00f3<\/strong>. Aquest \u00e9s probablement el punt m\u00e9s important i el que m\u00e9s encareix aquesta mena d\u2019habitatge, doncs sovint es parla de finestres amb triple vidre o tecnologia de miralls reflectants. Tamb\u00e9 \u00e9s important estudiar b\u00e9 la posici\u00f3 de la seva col\u00b7locaci\u00f3 sobre el mapa, idealment orientades al sud perqu\u00e8 deixin passar la llum del sol i ofereixin ombra a l\u2019estiu.<\/span><\/p>\n

Ventilaci\u00f3 eficient<\/strong><\/span><\/h3>\n

Una altra caracter\u00edstica d\u2019una Passive House consisteix en una ventilaci\u00f3 eficient i mec\u00e0nica<\/strong> perqu\u00e8 els inquilins comptin amb aire net i fresc cont\u00ednuament. A m\u00e9s d\u2019eficient, tamb\u00e9 haur\u00e0 de ser equilibrada, el que vol dir que hi haur\u00e0 d\u2019entrar i sortir la mateixa quantitat d\u2019aire; aquest no s\u2019haur\u00e0 de barrejar encara que l\u2019aire calent permetr\u00e0 escalfar l\u2019aire fred que hi ingressi.<\/span><\/p>\n

 <\/p>\n

Aix\u00ed, una casa passiva no hauria de necessitar mecanismes de refrigeraci\u00f3 o calefacci\u00f3 convencionals i la seva demanda seria inferior a 15 kWh\/m2 a l\u2019any; un 90% menys que una casa habitual<\/strong>.<\/span><\/p>\n

A Factor Energia no podem oferir-te un lloguer a una casa passiva, per\u00f2 s\u00ed podem ajudar-te amb la teva instal\u00b7laci\u00f3 d\u2019autoconsum solar<\/a> o amb el punt de rec\u00e0rrega del teu cotxe el\u00e8ctric. Si vols sumar-te a l\u2019energia solar o a la mobilitat el\u00e8ctrica podem gestionar-ho per tu.
