Hiya Burkhard,<br><br>I believe I'm now able to find time to contribute with a fair estimate of amount of SB buildings in Czech Republic, however I'd like to have some parameters as to what constitute a SB building?<br>
<br>My hesitation is that the predominant amount of buildings which I'll call 'SB buildings' are not legal as residential house; some are completely 'black', others build as recreational cottages, (but inhabited all year).<br>
Off the buildings which are residential, there's any number of imaginable architect fantasy of including some straw into a building while avoiding to confront the building offices! This used to be the case until the architects realized that there's nothing illegal about building a 'real' SB house, but unfortunately these high-embodied energy variations are continuing due to the desire to reach the so-called 'Passive house standards'.<br>
-Case example; building a solid concrete re-bar enforced structure, adding straw for insulation and covering with wood and/or hollow bricks.<br><br>No, my point here is not to start a 'puritist', nor a 'Passive House =High Embodied Energy' debate. I simply would like to know how you would like us to count the buildings in SB with straw in them? <br>
Only legal residential/commercial buildings?<br>Insulation of old residential/commercial buildings with SB?<br>Cottages? <br>Rough definition of a SB building? (At what level does SB become a means of 'green-washing', rather than an approach to building?)<br>
