Environmental Design - Market House

Page 1

Context: Shading

Market house, North Main Entrance is facing North East with taller surrounding buildings wrapped around the north, south. The sun path indicates that the site receives most sunlight in the latter part of the day. The south west opening of the site will receive the most sun light of all, and will likely have over-heating in the hot summer afternoons.
