Passive Solar vs Passive House EXPLAINED

[@tealkerberus748]

I am not living in a house passively warmed by the sun because in winter when I want my house to be warm, the sun is obscured by heavy clouds and all my big "sun facing" windows just let out whatever warmth we have from other sources. Passive solar sounds great in theory, but in practice in a winter-rain climate it's a very bad design choice.

Very interesting and well explained. 🇨🇦. Do you like SIP panels as an exterior wall assembly ?

Thank you! I'm happy to see you are enjoying the videos 🙂 SIP panels can also be used for Passive House projects and we are working on a few projects using SIPs.

I’m just completing my third project using SIPs (6 1/2” R37). Thermapan SIPs has never supplied a wall panel thicker than 8 1/4” (R47) even in the far north in Canada. There must be a “Rule of diminishing returns” relating to SIP panel thickness. Passive house standards are R75 which would be a 12 1/4” inch panel

@@qualitybydesign5119 If the tinsulation thickness in the prefabricated panels is not enough, then additional external insulation can be added to achieve the desired U-value.
