The Point, Boston
On June 21 by 12:00 Noon, the existing shadows move north and disappear totally on both Brookline Avenue
and the driveway to the east of the Project Site. The Boylston Street frontage still remains in full sunlight and
the shadows cast west of the Landmark Center on its front entrance disappear. At 3:00 PM, the existing
shadows move towards the east, partially over the driveway. Both Brookline Avenue and Boylston Street
frontages receive full sun exposure. By 6:00 PM, the majority of the surrounding streets are within the
shadows of the existing buildings.
Build Condition
At 9:00 AM, the Project casts additional shadows on Brookline Avenue, which already receives shadows from
existing on-site building. A small portion of the west parking lot at the Landmark Center also goes under new
shadows from the Project. At 12:00 Noon, the sun moves towards the Brookline Avenue frontage and a
portion of the driveway to the east and west façade of Trilogy. At 3:00 PM, the sun is located in a westerly
orientation where new shadows are limited to the driveway to the east, the west façade of Trilogy, and
frontage along Boylston Street. By 6:00 PM, the sun is due northwest and new shadows cover portions of the
Boylston Street frontage and the west façade of Trilogy as well as extend over several roof-tops of existing
buildings located south-east of the Project Site.
September 21
September 21 is the fall equinox where Boston experiences roughly equal length days and nights. The No-
Build and Build Condition shadow conditions are depicted on Figure 4.2c.
No-Build Condition
At 9:00 AM, the sun is located in the southeast. Similar to the spring equinox and summer solstice, the
existing on-site building cast shadows on most of the sidewalk along the Brookline Avenue frontage. The
driveway to the east of the Project Site is also under shadow cast by Trilogy while the Boylston Street frontage
is in full sun exposure. In addition, the Landmark Center casts its shadows towards the west by its front
entrance.
By 12:00 Noon, the sun is due south. At this time, shadows shift towards north and shrink on the Brookline
Avenue frontage. The driveway to the east goes under partial shadows from the existing on-site building
while the Boylston Street frontage remains in full sunlight. In the near vicinity, the shadows west of the
Landmark Center disappear.
By 3:00 PM, the sun is located in the southwest. The shadows along the Brookline Avenue frontage disappear
completely, while the driveway to the east goes under more shadows from the existing on-site building.
Boylston Street frontage remains in full sunlight during this time. At 6:00 PM, the sun has nearly set and most
of the neighborhood is in the shadows of existing buildings.
Build Condition
Under the Build Condition, at 9:00 AM the proposed building will cast additional shadows towards the north
over Brookline Avenue, which is already mostly in shade to the east, as well as by the front entrance of the
Landmark Center. At 12:00 Noon, the portion of the Brookline Avenue frontage that receives new shadows
from the Project shrinks and moves towards the northeast. Also, limited shadows fall onto the west façade of
