Will the leaves still be there in winter, or will they fall off and allow more direct sun through in winter? Also, I don't know, but would be curious if leaves are opaque to infrared. Depending on the species and thickness of leaves some are opaque to light, but others with thin leaves have a slight bit of green translucency. |

2015-08-21 09:38:47 -0500 | answered a question | State-of-the-art lighting design? For aggressive lighting power reductions, it's not a question of "state of the art" but rather what are the lowest illuminance levels an owner will consider acceptable, while also deemed satisfactory to occupants on multiple levels of visual and functional experience. Current technologies are a fairly level playing field and you can't say for certain that deploying technologies X, Y, and Z will give performance A. In addition to "how low can you go" it's also a question of where each criteria is deemed necessary, either as a blanket of uniform light across entire spaces, or if limitation of enhanced lighting at particular work areas will be accepted. I agree with a previous response (although I'm admittedly biased) that verification of targets by a lighting designer are the only way to determine a project specific answer. |
2015-08-20 13:41:54 -0500 | answered a question | Is it reasonable to use Simple Glazing System Window Materials object to recreate a Double-pane glass windows? Also, if you're doing more detailed daylighting simulations using Radiance, and the precision of the angular dependence is important, you may need to consider more complexity of the glass itself.
