Who is the Sun Path poster for?
Sun Path belongs to the Architecture section rather than to a school year, because design is not something one grade owns. Anyone learning environmental design can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Sun Path poster?
Draw it on the section before shading. Summer sun is high; winter sun is low and awkward. A wall chart earns its place by being glanceable from where the work is happening, so Sun Path belongs on the wall where that design work actually happens, within glancing distance, rather than filed away.
What other posters go with Sun Path?
Airtightness, Embodied Carbon and Orientation sit alongside Sun Path in the Architecture section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AirtightnessEmbodied CarbonOrientation
Is the Sun Path poster free to download and print?
Yes. Sun Path downloads as a free PDF with no account, no email and no watermark, like everything else in the Architecture section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Sun Path poster print at?
Sun Path is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Sun Path loses nothing.Printing guide
