The Glass Block
Goals of Augmen
Taking the standard glass block (non-
in this exercise) as a starting point, the
objectives were established in order to acc
the varying needs of the Urban Naturist:
Optimize daylight
Meteorological adjustment for solar ga
Nightly conversion to privacy screen
Additional aims of the augmentation
the glass block be maintained as an autonomo
that need only be plugged in. A wall config
these blocks is in the service of the inhabitant but does not neglect its neighborhood prese
finally, the smart block should produce its ow
if at all possible.
Based upon these goals, it appeare

when night falls, it should cater to the move

The Urban Naturist
Problems of Place
The Urban Naturist reluctantly dwells in the
city as his job, school or family requires, but he truly
longs to exist in harmony with nature. This includes
the desire to dispense with clothing in order to return
to a more natural state. The American writer Walt
Whitman describes it this way:
Sweet, sane, still Nakedness in Nature! - ah if
poor, sick, prurient humanity in cities might really know
you once more! Is not nakedness indecent? No, not
inherently. It is your thought, your sophistication, your
fear, your respectability, that is indecent. There come
moods when these clothes of ours are not only tooirksome to wear, but are themselves indecent.
Such a sentiment poses certain architectural
challenges for the Urban Naturist. By day, he seeks
access to sunlight and connection with the outdoors.
By night, he chooses to be free of the constraints of
city life while in the privacy of his own home. However,due to the density in which many city dwellers find
themselves, the Urban Naturist risks alienation, even
victimization, should he not draw his curtains tight
after dusk.
The plight of the Urban Naturist poses
opportunities to rethink transparency in the city
dwellers home.

Mulit-modal System
Sensing and Actuating
When the sun is shining on a given block in
summer, the photocell will trigger the fan to turn on,
thus creating a flutter of leaves in order to filter the
direct sunlight and cast a dappled condition on the
interior. When out of direct sunlight, the fan will not be
triggered and an LED instead will illuminate the block.
On a sunny day, on a south facing wall, a wave of
fluttering leaves will track the suns path. In the winter,
the sun will not trigger the fans so as to allow as much
direct sunlight as possible to penetrate to the interior.
Nightmode tracks the movements of the
inhabitant rather than the sun. When a presence isdetected by a given block, the fans will be triggered
and the leaves will flutter. Where no presence is
detected, the LED will illuminate the block. From the
exterior, one would observe the movements of the
inhabitants as a fluttering of leaves tracking across the
surface of the wall.

Working Prototype
Process of Elim
The greatest challenge in develo
working prototype proved to be the
specifically fluid dynamics, rather than iss
the sensor communicating with the actuat
sealed container it appeared a fan without
outlet achieved a kind of stalemate equilib
it proved difficult to achieve motion. Vent
top and bottom of the block was essential in
sufficient air flow. Even so, the minimal res
the grate caused problems and many mate
tested, including tissues, trace paper, Styrof
the bubbles from plastic packaging.
The addition of a screen covering the adding unwanted wind resistance, proved n
for smaller items that would get lodged in an
the fans. Plastic bags cut into small piec
having the additional issue of static, were
easiest to move with the given air flow.
Solution I, shown at right, involved
strips of plastic bags to the plastic meshthe fans. This had the unexpected effect o
a kind of parachute in which the plastic m
lifted up by the force of air on the attached s
result was ironic as what had proved most dif
succeeding in lifting the lightest of materials
fans. The final solution for this phase of th
was to cut the plastic bags into the initially de
shapes, and provided there were not too ma
objects in the block, they would indeed flutte
