UpTo35 - Meta Mosaic
Type
General Concept The challenge to design a student housing in the
neighborhoods of Metaxourgeio and Kerameikos, which have such complex
character, was addressed by the design of a building that interprets this
complexity into its formal and functional aspects.
The formal exploration used the concept of the ‘historical
triangle’ and of a mosaic (diversity of ethnicities and land use) as a
departure point. The intention of the building is to act as a metaphor for
transcending difference by its integration into a richer form.META_MOSAIC resolves the requirements of the project’s
program by providing an efficient system of self-sufficient units which provide
the residents with total independence in the one hand; and designing common
areas which provide for them opportunities for engaging in social interaction
not only with other students but with the neighborhood’s residents. The general
plan of META_MOSAIC therefore proposes along with a housing solution, the
design of vegetable roof gardens, a series of common spaces of flexible use and
a program of activities where the student body has the potential to contribute
to the social fabric of the district.Flexible SystemMETA_MOSAIC is built out of simple units, which can be
adapted to different functional needs. They can be combined for greater
community spaces or take different proportions at the recess levels for
accessibility needs. Overall it provides a framework for different functions,
allows for efficient planning and cost reduction. The units have an approximate
dimension of 6.30 meters depth and 2.80 meters wide. Each student unit is self-sufficient
and therefore allows for maximum functionality at all levels. This allows for flexibility
in the design process and permits the developer at anytime to combine two rooms
into one bigger domus commune with a
single bathroom, a single bigger kitchen and bigger bedrooms. Furthermore, the
uniform disposition of the units and the circulation areas allows the
possibility for a building to communicate at each level with its neighboring
entity by extending the corridor. While each building can work as an
independent entity, they can be combined into bigger ones and allow for greater
interaction.Community SpacesOn each rooftop, the folded structure of the building turns
into a pergola and creates shaded protected areas for a roof garden where
students can gather and grow their own vegetables encouraging an environmental
awareness.
META_MOSAIC occupies with its 16.10 meters depth 70% of the
building plot 29. This typology is systematically repeated on the other plots,
thus resulting in plots number 15, 16, 17 and 20 having bigger gardens in which
a range of community spaces are proposed. These spaces are designed as
independent pavilions, which are open structures and can be adapted or
transformed by the students. They can accommodate different activities such as
reading spaces, lounge, world café, fitness or outdoor movie spaces. On the
smaller plots, the community spaces are integrated into the unit system at the
basement level. They are lit and ventilated through an open protected sunken
garden.
The viral character of META_MOSAIC provides the students the
possibility to actively change and develop their environment thus engaging them
with the architecture at different scales.Plot 17 and 20 provide multi-storey parking supplies for the
neighborhood. Furthermore if requested, the parking space can be extended to
plot 15 and 16 while keeping the needed escape stairways on plot 17 and 20
(distance 25 meters).This project envisions a complex in which students have
controlled access to the numerous community spaces of the neighboring buildings
and thus constantly creating a flow of student interactions.Construction and Materials The structure of the building consists of load-bearing
concrete walls and prefabricated slabs. The local geotechnical requirements
(seism) for the structural system were taken into account by means of vertical
and horizontal slice models. The load-bearing interior walls are made of
sand-lime brick. This constructive solution ensures a cost-effective acoustic
insulation and contributes positively to the natural thermal regulation. The
compact form, a simple primer structure and the prefabrication of individual
components allow the reduction of construction costs.
META_MOSAIC offers a straightforward facade construction
principle. The design attaches importance to the use of natural materials:
sand-lime brick interior walls, prefabricated elements of the facade of treated
wood. The load-bearing wall is constructed out of 20 cm of concrete and 20 cm
of mineral insulation material. The folded triangulated skin acts independently
to the main concrete bearing structure. The exterior wooden panels and windows
are fixed to a series of lightweight pyramid wooden structures. Each panel is
provided with air cavities and rainwater gutters at each joint, thus allowing
the skin to be naturally ventilated and waterproof. Its relatively thick depth
assures for enough thermal insulation.
For the prime concrete structure, the cement content is
reduced by the use of recycled fly ash. For the secondary structural elements,
such as stairways, in addition to the fly ash, recycled materials is used for
the aggregate. The internal lining is finished with environmentally friendly
materials and almost all materials are PVC free products. The green roof
surface acts in addition to the thermal insulation.Ventilation and ComfortMETA_MOSAIC proposes an architecture that is integral with
the main natural ventilation principle of the building. It proposes a series of
folds, which have the purpose of accelerating the air circulation along the
building skin. The exterior panels are oriented in a sequence facing the sun
and inclined in a self-shadowing position. Consequently, the lower part of each
floor is heated up while the upper part lies in shadow. Throughout the levels
this temperature difference causes a natural upwards movement of air along the
building skin. Similar to breathing cavities, a series of triangular-shaped
pockets capture the ventilated air into the loggias. These loggias are
protected from direct sun and can act as winter gardens. In this way, the
pockets protect each room against the heat of the sun and provide fresh air to
living spaces. In winter, they provide naturally trapped heat from the sun for
the students.
On the roof, the pockets act according to the principle of
Bagdirs well known in hot dry countries. They act as windcatchers and solar
chimney thus creating a vacuum suction that draws cooler replacement air in
from the basement. At the outskirts of each plot, air entry fields are
positioned in order to provide fresh air from the gardens and cooled down
naturally under earth. According to the Bernoulli principle, the windcatchers
siphon air provided by the loggias through the student units. Through its
architecture, META_MOSAIC is entirely naturally ventilated.META_MOSAIC integrates a complex series of mechanical
devices for allowing the user to manually adjust his comfort needs. The façade
can be seen as a series of “leaves” which can be rotated, closed, flipped or
twisted in order to adjust the position of the main sunshade “leaf”, to retreat
the sides of the winter gardens, to close the shutter in front of the windows,
or to manually open the window. These features contribute to a constantly
adaptable aspect of the building without radically modifying the architecture.Energy ConsumptionSeveral active and passive measures reduce both the energy
consumption during the construction and the annual required energy by the use
of the building: solar contribution to the east and west facades and the use of
the thermal inertia of the structure. The additionally required heating energy
is covered by means of gas condensing boilers in combination with a solar hot
water system. These solar panels contribute to the heating in winter and
ensures the full recovery of hot water requirements during the spring and
summer months.A large proportion of the electric energy demand is covered
by the photovoltaic system. The collectors are located both on the upper facade
elements, on the roof of the main buildings and the roof of the pavilions. The
system is connected to the local network and allows the sale of any excess
energy. All electrical appliances meet the energy saving requirements.Regarding the water consumption, emphasis is put on the
efficiency of the installation as well as the regulation of the quality of the
water. Besides the use of water-saving plumbing devices, a grey water-recycling
installation is used. The green roof serves as a rainwater catcher area. The
rainwater and the filtered and recycled grey water from the shower will be
reused for the toilets. The effluent from the toilet is separated and channeled
sent to the wastewater system.This energetically technical approach creates an almost
autonomous unit, and allows in comparison to a conventional building for a
significant reduction in greenhouse gas emissions.
