Is anyone using a solar envelope in topical areas? Is there any software to assist in calculations? I used to build this manually, but was wondering if there is anything anyone can suggest.
Dear dear Beta, you can have a look at my paper: F. Asdrubali, F. Cotana, A. Messineo: “On the Evaluation of Solar Greenhouse Efficiency in Building Simulation during the Heating Period”, Energies, 2012, 5, 1864-1880 which is also present here in Research Gate
Dear Beta, I found this tool but I didn't test it yet : http://www.grasshopper3d.com/group/ladybug/forum/topics/solar-fan-solar-envelope-with-ladybug?page=1&commentId=2985220%3AComment%3A974292&x=1#2985220Comment974292
Hi Khoula,
Yes, I've been learning to use grasshopper, but not really mastering it yet.
Will try again, really nice suggestion.
I saw your paper also correlated with solar envelope, thanks to drop a comment.
Looking forward another discussion.
I apologize for my ignorance: what do you mean by solar envelope?
Dear Claude-Alain Roulet,
The first term of Solar envelope was issued by Ralph L. Knowles, at his book : Solar Envelope concepts he mentions that The solar envelope is a space-time construct. Its spatial limits are defined by the parameters of land parcel size, shape, orientation, topography, latitude, and the urban context. Its time limits are defined by the hours of each day and season for which solar access is provided to neighboring land parcels, and the time interval will vary according to land use and community attitudes toward the value of solar irradiation.
I've been doing several experiment for this solar envelope compile with urban form and massing parameter such as building coverage, floor area ration and ratio of space between building using autoCAD and sketch-up. but, somehow i haven't find the exact clue for building density and distribution
Though the question is old I write to suggest a new tool to generate solar envelopes https://www.food4rhino.com/app/solar-toolbox
