The following section describes the estimated shadows under the Build and No-Build Conditions.
March 21
March 21 is the spring equinox on which Boston experiences roughly equal length day and night. The No-
Build and Build Condition shadows are depicted on Figure 4.2a.
No-Build Condition
On March 21 at 9:00 AM, the Project Site is shaded along its two sides. Most of the sidewalk along the
Brookline Avenue frontage remains in shadows cast by the existing on-site building while the Trilogy
building creates shadows on the driveway to the east of the Project Site. The site frontage along the Boylston
Street is in full sunlight. In the vicinity of the Project Site, the Landmark Center casts its shadows west over its
front entrance and to the north over its parking lot.
At 12 noon on March 21 as the sun moves to the south, much of the shadows over the sidewalk along
Brookline Avenue get shorter and most of the driveway comes out of the shade of Trilogy. The Boylston
Street frontage remains in full sunlight. Also, the Landmark Center no longer casts its shadows by its front
entrance. By 3:00 PM, the shadows move east, allowing sunlight to shine through Brookline Avenue and
Boylston Street. Shadows are cast on the driveway to the east of the Project Site.
Build Condition
Under the Build Condition, at 9:00 AM the existing shadows on Brookline Avenue frontage will expand
towards the northwest over a portion of the Landmark Center. By 12:00 Noon, these new shadows clear off
the front entrance of the Landmark Center and fall on a smaller portion of the Brookline Avenue frontage.
The proposed building will also cast shadows on a limited portion of the driveway to the east of the Project
Site and on the west façade of Trilogy. At 3:00 PM, the shadows along Brookline Avenue clear off. Thus, the
only effect caused by the Project is partial shadows on west façade of Trilogy and on the site driveway.
June 21
June 21 is the summer solstice with the longest day of the year and the smallest shadows expected.
Figure 4.2b depicts the anticipated shadows cast by the No-Build and Build Conditions.
No-Build Condition
At 9:00 AM, the Project Site is shaded along its two sides: most of the sidewalk along the Brookline Avenue is
covered by shadows from the existing on-site building; and the driveway to the east is shaded by Trilogy. As
in the case of the spring equinox, the whole frontage along the Boylston Street receives full sun exposure and
the Landmark Center casts shadows to the west on its front entrance.
