PREVAILING WINDS

WIND ANALYSIS

How building sections affect solar exposure

DESIGN OBJECTIVES DERIVED FROM SUN AND WIND ANALYSIS

Dense urban pattern minimizes winter winds

Loose urban pattern maximizes cooling breezes in summer

Green areas can be formed to cool incoming breezes

Strrets oriented according to prevailing winds, maximize

wind movement and creates cross ventilation

East-west elongated buildings maximize solar gain while insuring solar access to

each building and decrease solar exposure in the afternoons

Buildings can be located at the top of the slope for exposure to wind

DESIGN OBJECTIVES DERIVED FROM BUILDING & SPACE TYPES

ANALYSIS

Public usage

Private usage

Semi public usage

Private usage (mostly residential) can be pushed to the outer edges

of the site in order to have a transition area between smyrna

and residential areas

Publıc use is mostly gathered around the historical site. To

reveal this historical site more , the periphery of the site can be

used as public spaces

AGORA TYPES ACCORDING TO THE FUNCTIONS

State agora: used for administrative, political

purposes.it was the meeting place for political assemblies

Commercial agora: used for trade activities as a market place

The harbor: a place was necessary to sell the goods that

came via sea trade to the harbor .so, the agora was either close to the harbor or in the city

centre.

The layout of agoras in the city of ephesus

The principal street: provides the main artery of circulation in

the city. (links the agora to the harbor and to the other public buildings or spaces of the city.

COMMERCIAL AGORA: closer to the harbor since it is for trading of the

goods

STATE AGORA: pushed to the edge of the city

AGORA TYPES ACCORDING TO THE LAYOUT

IONIC AGORA ARCHAIC AGORA

Agora of Priene Agora of Assos

of the agora

Grid layout of the agora

The layout of the agora and the surrounding buildings is in order and the agora is surrounded with peristyle columns.

There is no certain element that surrounds the agora . İt is just the buildings and they have no order.

PROPOSED SITE LOCATION DERIVED FROM THE URBAN ANALYSIS

Income estimate according to housing

types

Public &private spaces

Sun&wind analysis

The public spaces-generally around the

historical site- a chance to observe the

historical site

The common spaces in which the people

from different income types come together-

a chance to create public spaces around

smyrna that can integrate different

incomes, and by creating it on the

periphery of smyrna it may attract people

more to the historical site(revealing of the

historical site)

The pedestrian path that is most densely

used, comes from the coast and goes

through the proposed location-brings

human traffic to the site

The streets that are oriented towards the prevailing winds- lets summer breeze pass

through

The proposed site location: on top of the

slope- for exposure to wind&to benefit from

daylight&for integrating with the historical site

visually

ANALYSIS OF AGORA IN TERMS OF URBAN FABRIC, LAYOUT OF THE AGORA ITSELF& THE LAYOUT OF THE BUILDINGS

Urban fabric: organic growth

Layout of the agora: organic growth, the shape came out from the new buildings added

Layout of the buildings: rectilinear, surrounded by peri style columns, raised from the ground, hierarchy

of spaces

Athenian agora

ClosedSemi-openOpen

Stoa of attalos


Urban fabric: irregular grid

Layout of the agora: rectilinear, grid planned

Layout of the buildings: rectilinear, surrounded by peri style columns, raised from

the ground, hierarchy of spaces

COMMON FEATURES OF AGORAS•1-rectilinearity- in overall layout or in the buildings’ own layout•2-Hierarchy of spaces- closed, semi open, open- better integration between the interior and exterior spaces, use of living space as a threshold•3-Height difference from the ground level•4-public buildings gathered around the periphery

ClosedSemi-openOpen

THE THRESHOLDS BETWEEN SPACES

PUBLICPRIVATE

The buffer zone- bonds inside and outside-more ciculation in

between- more dense usage

COMMON FEATURES OF AGORAS

PUBLICPRIVATE

Thresholds that define the spaces

The buffer zone- bonds inside and outside-more ciculation in

between- more dense usage

BUILDING COMPONENT DERIVED FROM AGORA ANALYSIS

The spatial quality of the agoras (hierarchy of spaces, closed-semiopen-open) is applieed to the component. There is a softer transition between inside and outside

The patterned surface between the frames can also change according to the viewpoints or to the positioning of the sun

The distance and the angle between the frames changes according to the views from the building and the sun

The level difference also reinforces the idea of hierarchy between spaces

PARAMETRIC CHANGES IN DESIGN

steepstraight

How the curve controls the movement of the frames

Steep=more view of the surrounding

Straight= restricted view of the surrounding
