Project: 111 Meldrum Office Building
City Planning #: PDP130027
VFLA Project #: 2013-01
Shadow Study Summary
Project Summary
The proposed project is a six story office building located at 111 Meldrum Street and within the Downtown
District Zone (Canyon Avenue Subdistrict). The lot is zoned for six stories and the proposed height of 85 feet.
The zone also allows for a zero lot line design for the building, however in our design we have provided
setbacks along all sides. A shadow study was provided to the planning department as required for any building
over 40 feet tall. The sixth floor roof line is at 85 feet of the proposed building. The shadow study is
summarized in the following paragraphs.
Study Overview
A shadow study was performed on the proposed six story office building located at 111 Meldrum Street. The
shadows were generated using a computer modeling program called Revit Architecture. Since shadows are
always changing, we chose four days of the year to focus on; March 21, June 21, September 21, and December
21. These correspond to the summer and winter solstice, and the spring and fall equinox. This allowed the
shadow study to look at the longest, shortest, and mid-point shadows of the year and is typically the days that
are studied for shadows. We also looked at three times for each day; 9am, noon, and 3pm. This allowed the
study to look at the change of the shadows throughout the day.
Conclusion
March/September 21
The shadows for March 21 and September 21 will be the same since they are the spring and fall
equinoxes (same amount of daylight as darkness). The shadow of the proposed building reach into the adjacent
alley to the west at 9am and the building's set back off the north property line allows for sun to reach the
northern adjacent building at 9am. By noon the shadow runs directly north and doesn't pass the adjacent
property's northern property line. The shadow is compact. By 3pm, the shadow has shifted in Meldrum Street
where it reaches half way into the street. In summary, the adjacent buildings have access to sunlight and are not
fully blocked by the buildings shadow.
June 21
June 21 is the longest day of the year and the sun is the highest in the sky. This creates the shortest
shadows. Our graphics show that the shadows barely reach the west alley and building to the west at 9am,

barely bleed onto the property to the north at noon, and allow for day light on to the southern facade of the
building to the north at 3pm.
December 21
On December 21, the longest shadow day of the year, the shadows of the building reach Mountain
Avenue at 9am, noon, and 3pm, however the shadows do not reach the buildings on the north side of Mountain
Avenue. Even though, the shadows are the longest on this day, the number of affected buildings has not
increased. This is a result of the site's location and relation to Meldrum Street to the east, Mountain Avenue to
the north, and a parking lot and alley to the west.
In final summary, the shadow study shows that the proposed building allows sunlight to the adjacent buildings
throughout the changing times of the year. The shadows do reach three buildings on the longest shadow day of
the year, but the most affected building, at 401 Mountain Avenue, is owned by the same owner as the proposed
office building. Additionally, the client and design team, have met with the other adjacent property owners to
discuss the proposed project and have their support of the project. The overall goal of the office building is to
improve and incorporate into the downtown fabric.
