I’ve downloaded a solartube from the RUGI site that will be ideal for a project I’m currently working on.
However, rather than placing the solartube in a roof, I wish to put it in the top of a tunnel. The ‘roof’ of the tunnel has been created using a conc ‘floor’ slab, and therefore will not host the solartube. I should add that above the tunnel ‘roof’ slab I have a layer of earth and then the garden yard, created as another ‘floor’ structure. (In summary, from top down; I have a ‘floor’ (paved yard) with earth (actually a void, no material specified) and another ‘floor’ (tunnel roof).
Any ideas on how to place the solartube in the tunnel ‘roof’?
