The architecture of the museum evolves out of overlaying the rationale of the historical urban structure of the precincts with the poetics of an ascending and spiraling pedestrian promenade. The intimate courtyard of the existing urban block is transformed into a city court articulated by the galleries on the south and west. The court in turn becomes the container of a ‘Winter Garden’ that continues along the descending spiral.
“overlaying the rationale with the poetics”
GH-8830427044
“symbolic gesture of departure and reconciliation”
The ‘City Stairs’ sweeps up from the harbor front towards the ocean and then spirals on itself finding its way back to the city.
The upward movement provides for a holistic appreciation of the context and also frees the ground plane opening up possibilities for physical and visual connections across and below it.
The city court contains the ‘Winter Garden’ that is perceived to be a green haven that shelters and protects the city’s people from the extremities of climate. In being located at a threshold it also aspires to be a warm and welcoming beacon like portal to the city.

The museum hence becomes a singular gesture of the 3 components; ‘The Winter Garden’, ‘The City Stairs’ and ‘The Galleries’ that come together as a whole celebrating the union of Nature, Man and Culture.

Design and orientation of the galleries helps to increase solar exposure of the winter garden during winter months, trapping solar energy and increas-ing the air temperature inside. The same galleries and landscaping helps to shade the Winter Garden during Summer Hours.

Summer- Cooling through natural ventilation Winter- Trapped heat for increasing building temperature
Wind Buffering
The challenge is to conceive of a design that can perform exceptionally well during intensely cold conditions, yet remain open and engaging throughout the year. Counter to what might first come to mind, a lightweight cladding system, enabled through innovative materials, is also the key to minimizing embodied carbon of the structure and total environmental impact of the project. For inspiration we looked towards nature, intrigued by the incredibly clever arctic fox that had evolved to thrive in this widely varying climate. Specific elements we aimed to encapsulate in the design were a compactness of form, buffering from wind, high performance insulation, capture of solar energy and countercurrent radiant heat exchange.

Glazed Winter Garden
Compactness
By thermodynamics, a reduction of surface area to volume will limit thermal losses to the surrounding environment. As a response, to limit heating energy, we incor-porated a compact courtyard scheme with a glazed winter garden to trap solar energy in the complex’s core.

High Performance Insulation and Solar Energy
One of the most unique aspects of arctic animals, such as the fox or polar bear, is its hollow fur fibers. While giving the appearance of white, a result of light scattering, these animals are in fact black to help absorb solar energy. The project makes use of a translucent aerogel insulation in the core of the building through the winter garden atrium to achieve a similar effect at an incredible R-10 per inch.

Heating Load without Winter Garden= 30BTU/ sqft i.e 40,35,000 BTU for the musuem
Heating Load with High performance Insulation: 24 BTU/ sqft i.e. 32,28,000 BTU
Heating Load with High performance Insulation + Winter Garden: 18 BTU/ sqft i.e. 24,21,000 BTU
Countercurrent Heat Exchange
Like the intertwining of arteries and veins to help maintain a consistent temperature even at the extremities for arctic animals, the building makes use of radiant heating, fed from an array of staged Gas Absorption Heat Pumps and cooling directly from the harbor with an interlocking array of loops within building walls and floors.
