May you don\u2019t know us yet, let\u2019s have a quick introduction: we’re ERA architects. <\/p>\n Insulation is the 2nd must-have of a positive house. <\/p>\n What does insulation mean?<\/b><\/p>\n To insulate means to protect your house from the climate by placing a surrounding material to prevent the loss of heat and cooling (it also helps prevent the intrusion of sound). And you\u2019ll be thinking, how does this work in summer? I would never use a blanket in summer? Jokes apart, your house can produce heat or cooling by using the climatization systems. So, basically the insulation keeps the heat and the cooling inside for longer than we\u2019re used to. Meaning, less consumption in energy.<\/span><\/p>\n <\/p>\n So, there are 3 things to consider about insulation:<\/p>\n <\/p>\n 1) Calculate Insulation\u00a0<\/strong><\/p>\n First, insulation must be calculated by using the passive house simulator. 2) Draw Insulation as calculated<\/strong><\/p>\n Secondly, the architect must draw a detailed side cut view. 3)\u00a0 Continuous insulation<\/strong><\/p>\n Finally, the insulation must be continuous and surround all the house. <\/p>\n <\/p>\n Our professional recommendation: You may also be interested in: <\/p>\n <\/p>\n Hope this post ‘Insulation in a positive house’<\/em> is helpful!<\/p>\n Best of luck on this adventure. <\/p>\n P.S.

\nActually, I’m Esther Rovira, architect and passive house designer in Barcelona, Catalonia and Andorra for either passive houses, efficient houses and positive houses.
\nIn this post\u00a0\u2018Insulation in a positive house\u2019<\/em>, You will find our professional recommendation.
\nI hope it helps, let’s go!<\/p>\n<\/div>\n
\nMay you skipped the first, please check our post: ‘6 musts for a positive house’<\/a><\/span><\/p>\n
\n<\/span>Definitions a part, it means to put a blanket wrapping your house.
\n<\/span>It\u2019s like you do in winter when you watch a movie: you use a blanket to keep your heat from going away.
\n<\/span><\/p>\n
\n<\/span>Well, you\u2019re a human and you produce heat naturally, while your house is a thing and does not produce heat naturally.
\nWell, technically your house will produce heat if you give a pizza party. In that way the oven will be producing heat and your family and friends will also produce heat (so if it\u2019s summer, you\u2019ll be more cozy doing a salad party outside by the pool!).\u00a0<\/span><\/p>\n
\n<\/span>This means that if you want to have a nap after lunch on a burning-hot summer day (35\u00baC); you\u2019ll be most probably choose to have it inside with the AC. Then in a positive house, you’ll be using the cooling system for 10 minutes to cool your room for the rest of the afternoon. (Mind to use the alarm for that nice nap!)\u00a0<\/span><\/p>\n
\nThe simulator gives you the specific insulation thickness for your house\u2019s roof, fa\u00e7ade and slab. And it does take into account all the parameters of your house (<\/span>for more details on the parameters that the positive house simulator uses, please check ’10 keys to a positive house’<\/a><\/span><\/span>.
\nYou need to know that most architects don\u2019t have the knowledge to do this. So they will hire another person to do this. That could mean more expensive services, but even worse, losing information with the multiple agents with little specific knowledge. I do recommend you to consider an architect that is also a passive house designer.<\/span><\/p>\n
\nHere you\u2019ll be able to check the thickness of every piece of insulation on your roof, fa\u00e7ade and slab.
\nThis drawing must be in scale and the thicknesses must match the values from the passive simulation to be able to certify your positive house.<\/span><\/p>\n
\nThis means that the insulation on the slab must connect with the facade\u2019s insulation with nothing breaking into it.
\nThe same happens with the connection fa\u00e7ade-roof: insulation must be continuous. No breaks.
\n<\/span>May there be breaks, then they need to be calculated as what we call: thermal bridges. Then inserted into the passive simulator to check the effects of this leak of\u00a0 comfort in your house.<\/span><\/p>\n
\n<\/strong>Ask your architect to deliver a section cut with the insulation thicknesses with dimensions and in scale before construction starts.
\nMay he not be able to deliver this, he hasn’t though all the encounters and this for sure will cause some thermal bridges and your house will not be 100% efficient.<\/p>\n
