0.0 preface

Mode:

inputs

idle - at surfa

- Temperature via a

temperature sensor - Humidity percentage via a humidity sensor parameters checked: - minimum 6h of sunlight if True -> do nothing else -> illuminate the structure with

Biobulbs

(replicate sunlight)

>>Brief: Re_build: making & materials

- Humidity>90%

if True :> close the shield if False ->do nothing - For Temperature

<13C or >30C

Re_Model

Do ->close the panels.

Objective:

output

Creating a moving model which consists a further synthesis of my 4.2 submission, a chance to illustrate and consolidate the range of skills I have acquired from this year in Re_map and summarise my progress in this atelier. My model specifically is a roof structure with moving panels that open and close according to the humidity and temperature live data of the environment that the Arduino connected sensor receives. Learning outcomes: Extension of the basic knowledge of Arduino scripting acquired through the workshops and individual research and further knowledge in the field of digital fabrication. Studio 4.3

1.0

The extruded red, blue and pink circles draw ventilation inside each of the venues and also create tension nodes for the steel structure beneath the white skin. Some natural light permeates this PVC membrane, while entrances are contained inside all the spots that meet the ground.

precedentsRoof structure

The buildings are naturally ventilated with the introduction of a second inner membrane - the 2m-wide void between the inner and outer fabric skins provides an insulation layer and initiates an airflow, with warm air rising and exiting through the high level ventilation extracts and cooler fresh air being drawn in at low level. After the Games, the fabric, tensioning rings and connectors will be transported to new event locations. As the architect puts it: “There is no waste and the venue won’t leave a trace.”

In order to develop a more sustainable creative and achievable roof shape, numerous searches through tensile roof structure with openings were established. The precedent shown here are the temporary shooting galleries for the London 2012 Olympic games by Magma Architecture. The Olympic Shooting Venue comprises three PVC tents that have been erected at London’s historic Royal Artillery Barracks in Woolwich1. 1 http://www.bdonline.co.uk/technical/magma%E2%80%99s-london-2012-olympic-shooting-venue/5040101.article

Fig. 1.0 + Fig.1.1 + Fig 1.2 (right pg): The openings serve as tensioning nodes, ventilation openings and doorways at ground level.

[Re_Map]606: Post Capitalist Urbanism

18,000sqm of phthalate-free PVC membrane covers the modular frames. PVC was selected for its tensile strength, thermal performance, translucency and environmental properties, being 100% recyclable. Steel rings braced against the frame push and

pull the outer skin, tensioning it to prevent fluttering in wind and ensuring there are no flat planes where water can collect. The steel rings also provide openings in the walls and roof for ventilation and doorways at ground level.

2.0 Roof structure development

The new roof structure design was inspired from the Magma temporary galleries. The pivoting panels lay on top of the circular tension nodes enabling sunlight an natural ventilation. Studio 4.3

The video puts the code of the circuit to the test by placing my finger on the humidity an d temperature sensor (DHT22). This increases the humidity to >60% an thus the servo motor closes the roof panel attached to it.
