China Pingdi, Longgang Weather

The pilot zone of the Shenzhen ILCC lies at Gaoqiao area on PINGDI Street, Longgang District. It runs along the Dingshan River and covers the area north to Huanlong Avenue (north pathway), west to Jiaoyu Road North, east to Gaoqiao Road and the area within the ecological line of the surrounding mountains. The total planning area is around one square kilometer.
The contest aims at collecting the cutting-edge urban design philosophy and innovative ideas on construction of the land. The formal notice for the urban design competition is planned to be released on 15 January 2015.
Pingdi is situated at 22.77° North latitude, 114.3° East longitude and 19 meters elevation above the sea.

Arduino 2.27.15

Arduino Progress 

First Try (Simple Exploration)

The easiest way I've managed to measure a resistive sensor is to connect one end to power and the other to a pull-down resistor to ground. Then the point between the fixed pulldown resistor and the variable photocell resistor is connected to the analog input of the microcontroller.


Vo = Vcc ( R / (R + Photocell) )
This basically works by making the voltage proportional to the inverse of the photocell resistance which is, in turn, inversely proportional to light levels. The resistance of the photocell decreases, the total resistance of the photocell and the pulldown resistor decreases from over 600KΩ to 10KΩ. That means that the current flowing through both resistors increases which in turn causes the voltage across the fixed 10KΩ resistor to increase. This is the simplest method I have tried to date.

This may be the next step to take. Here is a diagram of the breadboard layout that implements a third party photosensitive sensor module.

FIREFLY _Project 1

“Firefly” dramatically reveals how wind moves around and through it. The hinged, polycarbonate panels swing with the unseen patterns of the wind. Each panel has a small embedded magnet that connects with an electrical reed switch. By day, the work appears like rippling waves of glass. By night, the back and forth swinging of the panels trigger the flickering of tiny led lights. The illumination of this entire sculpture requires less energy than a 75-watt light bulb. The artwork also serves as a gantry for a series of power-generating, vertical axis wind turbines that power the lights as well as feeding electricity back into the building. A collaboration with KMD Architecture and commissioned by the San Francisco Arts Commission for the Public Utilities Commission. Completed in 2012.

CJ R&D Center kinetic facade _PROJECT 2

Testing the next evolution in commercial building skins the CJ Cheiljedang Research and Development Center’s unique responsive facade controls solar gain over a significant range of exposure. Yazdani Studio of Cannon Design was tasked to create a marquee office and research center in Seoul, South Korea. Their solution was to create three tear drop shaped towers radiating from a glass atrium shrouded in a kinetic shade.

The accordion folded window shading wraps all three towers to provide a level of protection from solar glare. In key areas the shading folds to maximize solar control using a custom designed retractable mechanism. Based on the simple umbrella and developed on the 3ds Max software platform the perforated steel strips installed on scissor actuators can open or close automatically to ensure proper natural light levels while reducing overheating. Each unit is set between floors in groups of three ribbons, allowing the windows to be fully covered or fully exposed.  When open the façade provides shade protection from the overhead summer daytime sun.

Similar Project to above....


kiefer technic showroom _PROJECT 3

Ernst Giselbrecht + Partner

Ernst Giselbrecht + Partner present the Kiefer Technic Showroom, an office building and exhibition space with a dynamic facade that changes to outdoor conditions, optimizing internal climate, while allowing users to personalize their own spaces with user controls.

The shell construction of the facade consists of solid brick walls, reinforced concrete ceilings and floors, and steel encased concrete columns. The facade consist of aluminums posts and transoms with protruding bridges for maintenance, with an EIFS-facade in white plaster. The sun screen operates on electronic shutters of perforated aluminum panels.

Real World Examples

Examples of Operable facade mechanics and details. 
In order from top to bottom, Step motor attached to cable, Linear Actuator Arms, Hydroponic pump on pivot arm, Step motor with cable cord, common motor used in operable louver facades.
 

 

Notable System 


Shown is a previous M.Arch project using operable panel project using the same technique as the Kiefer technic showroom (https://www.youtube.com/watch?v=rAn4ldWjw2w). Kiefer uses a motor and cord system attached to wheels within the inset groove of the vertical bracing. Cords attached to the motor reel up the wheels attached to the corners of the facade much like a fishing rod.

Physical Model Mechanics

Ardiuno board can be used to do simple tasks as to turn off and on LED light or as complicates to control whole house HVAC, indoor/outdoor temps, and ceiling fan speeds. Current projects documents on the Ardiuno website range from wifi controlled RC cars to iphone operated missile lauch buttons. Implementation of Ardiuno boards in architectural physical models is becoming more popular as the demand for operable pieces rise. Ardiuno is a very feasible route for physicals models to meet the expectations of portraying an operable facade.

Wind Response

Idea Driven by Auto Industry - fins drive air to cool engine, funnel to cool tires, stabilize uplift and hug road.

An idea: what if we looked at the wind function as a diurnal process-shading by day and a reconfiguration at night to allow night flushing, harness to turbines, etc.  


A subtractive process in the doors...could speak to a facade that pulls in towards the curtain wall to create wind channels


Lower door scoop could become fins that could be solar as well as drive wind to cool or be harnessed for energy, etc.


Just another example of pulling and harnessing wind. The lower scoops here cool the tires and brakes. Upper scoop over back window pulls air toward the rear engine drive to assist with high temp cooling.

Louver System

Insolar louver system This definition extends the GH powercopy to be parametrically associated with the solar geometry obtained through the insolar radiation algorithm. It is part of a larger series related to the idea of Environmental Parametrics.

Solar Insulation Ideas

inflatable Ethylene Tetra Fluoro Ethylene (ETFE) skin. A solar-powered automatic light sensor, that regulates sunlight and temperature for the structure, controls the skin. Essentially the skin is a dynamic form of insulation and super energy-efficient window in one. The ETFE skin allows light to filter through but shades the people inside from direct sunlight, reducing UV rays by 85%

The distinctive properties of the material should not only become a mere actuator replacement but be orchestrated for their aesthetic qualities. EAP is a highly attractive component for kinetic architectural applications due to its extreme flexibility, lightness, thin dimensions and smooth actuation.


EAP is a polymer actuator that converts electrical power into mechanical force. In principle it consists of a thin layer of very elastic acrylic tape sandwiched between two electrodes.  Once the voltage in the range of several kilovolts is applied between the electrodes, the polymer changes its shape in two ways. First, due to the attraction of the opposing charges, the film is squeezed in the thickness direction (up to 380%), secondly, the repelling forces between equal charges on both electrodes result in a linear expansion of the film. As a result, after actuation the film becomes thinner and its surface area increases. If the supportive frame is flexible, due to the initial pre-stretching of the acrylic film, the frame bends. After application of voltage, the material expands, and the component flattens out.

The triangular pillows on the southeast side inhale and exhale like lungs to provide sensor-controlled sun shading. The long cushions on the southwest fill with nitrogen to block heat and filter light; in 30 minutes, a beautiful, cascading nitrogen cloud responds to the rising temperature outside, replacing a conventional air conditioning system, which can account for 80 per cent of a building’s energy consumption.
