Circulation & Interaction 13

HEAT MAP OF USER INTERACTION

PRIMARY POINTS OF INTERACTION:

Ticketing, entry lobby, central courtyard, grand spiral stair, museum shop, rooftop restaurant, roof garden, theater

POINTS OF LEAST INTERACTION:

Gallery space, storage room, toilet rooms, back of house offices, portions of artisans’ workshop spaces Gallery exhibit spaces were designed as narrow passageways with no windows to eliminate distractions of the exterior and direct visitors’ attention to the artwork on display. This is an area of decreased interaction as users’ pass through and observe somewhat quietly.

When the exhibit space ends, the design opens up with views to the central courtyard and provides space for interaction between visitors and artisans in their studios. The various levels of the museum allow for an undulating experience of quiet observation with minimal interaction and then opening to encourage interaction.

SOUTHEAST ELEVATION

Analysis: The southeast elevation will require some sun shading to protect from the direct sunlight on the hottest days.

A horizontal shading device above southeast facing windows, angled at 50 degrees, will block summer sun throughout much of the day while still allowing the sunlight into the building during the winter months when the sun is at a lower angle.

NORTHEAST ELEVATION

Analysis: The northeast elevation will require no horizontal or vertical shading to limit sun exposure.

In Boston the majority of the year is cold weather so heat gain from the sun is a benefit on most days. Additionally, the only northeast elevation in the design is an interior courtyard wall where light and views should be maximized.

NORTHWEST ELEVATION

Analysis: The northwest elevation will require no horizontal or vertical shading to limit sun exposure.

The northwest elevation faces uphill towards a 3-story building so much of it is already shaded. The buffer space between the proposed design and the existing 3-story building will be planted with trees and other vegetation that will further limit the sun exposure through any windows on this facade. Finally, the interior space here is primarily bathrooms and exhibit space where little direct sunlight is desired.

Analysis: The southwest elevation will require the most shading in this design: this facade faces about 15 degrees west of direct south, so it receives a lot of direct sunlight which would cause discomfort in hotter summer months.

Horizontal shades about these southwest facing windows should be installed at 60 degrees. Vertical shades to the west should also be added at 75 degrees.

DESIGN STRATEGY #1 SUN SHADING OF WINDOWS

Windows are oriented to maximize passive heating for winter sun exposure but limiting the direct sunlilght on the hottest days of the year, especially on southern facades of the building.

DESIGN STRATEGY #2 GLAZING SELECTION ACCORDING TO ORIENTATION

Rather than utilizing the same glass on each facade, the building incorporates clear glazing on the south facade to maximize solar heat gain. Low-E, high performance double pane glass should be used on west, north and east facades.

DESIGN STRATEGY #3 INCORPORATE COURTYARDS

Provide sunny wind-protected outdoor spaces to extend living area in cool weather climates: This was an important element in the design of the arts and crafts museum in Boston. Providing an outdoor courtyard with natural light and vegetation that is protected from the wind greatly expands the useable space for much of the year without increasing demand on the building’s heating and cooling systems.
