The formation of the people will
effect future planning of the

Aim for non-market days:
-To provide a comfortable resting area
-Increase footfall in non-market day
-Increase the use of the ground area
-Encourage the use of the Portobello Green
The routes of people are similar in the two mapping
besides the quantities of the people in area. The
new design will aim to invite people in walking
trough the space and be attracted to use the
space.
Aim - Re-energize:
-Resting point to increase football of zone c
-Lighting show to emphasis the effect of
Thermal electric generation
-Recreation of the atmosphere using lights in
the constantly shaded area
Given that the most populated area are
where the market stalls are, the new design
must also include space for the existing stalls.
It will also attract people to stay in absents of
the market in order to fully utilize the area

Part 1 Dividing the surface into grid
Creating the basic square grid
The part of the script creates a rectangle by joining 4 points
together, the rectangle was then divided into 16 individual
square all at 1m X1m each. The number 16 is the maximum
hours of sunlight presents in any day of the year.
Tilting the bottom frame:
By rising two corner points which forms the rectangle, I can tilt
the modules to an adjustable angle

The use of digital scripting allows me to build a parametric

Part 2 Alteration of each components
Part 3 Additional development to the modules
This component controls the height of upper part
of the module in relation to the bottom frame
structure
Angle of Altitude and Azimuth
The script enables flexibility in
terms of adjusting the angle of
rotation in the TEG unit as well
as the height, enabling adjust-
ment to be made on each
module as they interact with
the parameters.
As previously explained, the
modules are designed to
‘follow’ the movement of the
sun in order to retain in direct
contact to the solar ray which
will then be concentrated by
the Fresnel lens to generate a
concentrated zone with
extreme heat.
The parameter needed was the
altitude and azimuth of the sun
which I have Obtained from the
Autodesk EcoTect program.

The order of the row are in reverse to the altitude of the monthly
sun-paths. This is to avoid the light interruption from shadow of the West
way motorway which is directly at the south of the whole structure.
The month with the highest sun path will be least effected by the shadow
of the West way which is the reason why the TEG row are arrange in this
manner starting with the arrangement of TEG module in the month with
the highest altitude in its sun path (July)

COMPUTATIONAL DESIGN - PARAMETRIC SCRIPTING
AXONOMETRIC STUDY OF FUNCTION AND LAYER
-
The energy collect from the TEG
surface will be used for re-energizing
the area. The solar lighting simulates
the movements of sunlight of the
daytime, changing according to the
time of year
The appearance of the sun light
simulation evolved from the idea of
how the local residents and tourists
utilize the space throughout the year.
The number of activities and the
number of people using the space
are often higher in the Summer
period when sun lights is present.
Therefore by recreating a sun light
environment, the design will aim to
attract people when the sun light is
absent.
On Market days
The area underneath the walkway will act as a shelter to
the market stall as well as lighting the market area. The
area at the top of the walkway is design for people to
rest, allowing them to continue walking towards the end
of the market where the footfall rate is the lowest.
On Non-Market days
The area underneath the walkway will be used as a street
performing platform or an area for social gatherings. The
top of the walkway will act as an viewing platform,
allowing people to experience the lighting performance
of the TEG surface.
SOLAR LIGHTING PERFORMANCE
The supporting columns runs from the
TEG surface, through the Split floor
and to the ground
The Split level act as an additional
route in the busy market day as well
as a viewing platform of the TEG
surface and a performance space
underneath

the core TEG unit which would then lead to generation of electricity

Plan view of the design
The new TEG skin provides additional ecological benefits in relation the
previous tensile structure. The main focus of the design was to increase
the utilization of the natural energy resources in the area, whiles re-ener-
gising the space.
The design makes full use of the solar radiation available, transferring the
radiation into heat creating a high temperature differences between the
TEG surface which enables it to generate electricity.
The electricity will then be stored and used for lighting performance
which will enhance the use of the area by other.

Key
Artificial Light Natural sun light Wind
The transparent materials used will enable most of the natural the light to
penetrate through minimising the amount of light reflected off the
surface
The electricity of the lighting solely rely on the electricity provided of the
TEG surface and will only be on when day light is not present.
The light will also generate a large amount of heat energy which will
help regulate the area when the temperature drops after sunset
Heat
The division of space enables body heat and
heat energy form the lights to be intercepted as
it rises which will again contribute in regulating
the temperature of the space
The design enable enough space for ventilation
which will help to regulate the temperature of the
space in the summer period
