Trilogy. At 3:00 PM, the sun shifts west and new shadows are limited to portions of the driveway to the east
and the west façade of Trilogy. The frontage along Brookline Avenue and Boylston Street is in full sun
exposure. By 6:00 PM, most of the neighborhood is in shadows, as the sun is very low in the sky and,
therefore, very limited amounts of net new shadows are experienced.
December 21
December 21 is the winter solstice and the shortest day of the year. Boston experiences long shadows
throughout the day in most locations. The No-Build and Build Condition shadows are depicted on
Figure 4.2d.
No-Build Condition
At 9:00 AM, the sun is located almost in the south and low in the sky resulting in expansive shadows towards
the north. Under the No-Build Conditions, all of the Brookline Avenue site frontage and portion of the
driveway to the east are under shade while most of the Boylston Street frontage is in sunlight. The Landmark
Center casts shadows north over its parking lot. At 12:00 Noon, the existing on-site building shades most of
the Brookline Avenue frontage and a portion of the driveway to the east. Like the summer solstice and the
two equinoxes, the Boylston Street frontage is in full sunlight. At 3:00 PM, the sun is located in the southwest
and low in the sky, shading the majority of the driveway to the east. The Brookline Avenue frontage is mostly
clear of shadows and the Boylston Street frontage continues to receive full sunlight. The sun sets
approximately at 4:15 PM EST.
Build Condition
At 9:00 AM, new shadows are limited to the sidewalk along Brookline Avenue, the southern façade and roof
of the Landmark Center, and several roof-tops of existing buildings just north of the Landmark Center. By
12:00 Noon, new shadows move over the sidewalk along Brookline Avenue towards the northeast as well as
over a small portion of the west façade of Trilogy. At 3:00 PM, the sun is low in the sky and shadows
dominate the area around the Project Site. New shadows are cast by the proposed building largely in the
northeasterly direction and fall on a portion of west façade of Trilogy. The Brookline Avenue frontage comes
out of shadow and the Boylston Street frontage remains in full sunlight during this time. The sun sets on
December 21 approximately at 4:15 PM EST.
Daylight
The following section describes the anticipated effect on daylight coverage at the Project Site as a result of the
Project. An analysis of the obstruction of skyplane under the No-Build and Build conditions is a requirement
of the Article 80 Large Project Review (Section 80B-2(c) of the City of Boston Zoning Code). The daylight
analysis was prepared using the BRA’s Daylight Analysis Program (BRADA) and has been completed in
accordance with the requirements of Article 80.
