Responsive environment Awnili Shabnam Design Studio: ATMOSPHERE, OCEAN: NO BLUE, NO GREEN

Something that is as vital to the sustenance of life as the oceans, that also scatters light to acquire its blue hue, is the atmosphere in which we live and breathe. In every cubic metre around us scientists tell us there are approximately 2.5 x 10 raised to the power of 25 molecules engaged in a restless and variable colliding interaction. We can’t see them, we can’t count them, we can’t model or simulate them, but we are sensitive in every way to what they are, and how they are behaving. We can manipulate them at the collective macro scale.

The Designing Responsive Environments

Studio engages at the phenomenal level with the turbulent world of atmospheric dynamics that shape our environments leading to more subtly sensitive, responsive and energy conserving design solutions. In the ubiquitous computing era, designers can now capitalise on real-time data to inform their design. Dynamic phenomenal changes in the environment, such as light, temperature, humidity, air quality and movement can be traced with sensors and visualised to inform the design process. The opportunities come with the advent of off-the-shelf sensors, microelectronics, smart phones, new and smart materials, and augmented reality tools.

Aims of the Studio:

Studio Directives

• Deepen our understanding of Global Warming

• Understand why we are so deeply connected to it

• Find out whether, given that buildings and cities are the first cause, can they also be part of the solution? Can we, as designers be part of the solution?

• Explore radical and reachable approaches: cloud seeding, designing with and in symbiosis with atmosphere

A. Pre-design research

A1.Atmospheric phenomenon: Precipitation

Metamorphosis of water

Water transforms continually from one form to another sustaining life on earth. The water cycle consists of evaporation and transpiration (evapotranspiration), condensation, precipitation, and runoff. precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. It is a major component of the water cycle, and is responsible for depositing the fresh water on the planet. The main forms of precipitation include drizzle, rain, sleet, snow, graupel and hail.

Form of precipitation

Rain Sleet

• Coalescence occurs when water droplets fuse to create larger water droplets, or when water droplets freeze onto an ice crystal, which is known as the Bergeron process.

• When air turbulence occurs, water droplets collide, producing larger droplets.

• As these larger water droplets descend, coalescence continues, so that drops become heavy enough to overcome air resistance and fall as rain

• Ice pellets or sleet are a form of precipitation consisting of small, translucent balls of ice. Ice pellets are usually (but not always) smaller than hailstones

Snow flakee Hail

• Snow crystals form when tiny supercooled cloud droplets (about 10 μm in diameter) freeze. Once a droplet has frozen, it grows in the supersaturated environment.

• Water droplets are more numerous than the ice crystals the crystals are able to grow to hundreds of micrometers in size at the expense of the water droplets.

• Hail forms in storm clouds when supercooled water droplets freeze on contact with condensation nuclei, such as dust or dirt.

• The storm's updraft blows the hailstones to the upper part of the cloud.

• The updraft dissipates and the hailstones fall down, back into the updraft, and are lifted again.

Random International: Rain Room

London

Rain Room is an environment of falling water through which it is possible to walk, trusting that a path can be navigated, without being drenched in the process. As you progress through the space the sound of water and a suggestion of moisture fill the air, before you are confronted by this carefully choreographed downpour that responds to your movements and presence.

Canopy over Piazza Faber,Sardinia

Renzo piano and alvisi kirimoto + partners

Renzo piano and alvisi kirimoto + partners have added a vibrant and ever-changing installation to the rustic piazza faber in sardinia the project comprises 12 suspended elements set against a backdrop of historical stone buildings and the market arcade. in celebration of the light and colors of the landscape, green, gold, red and blue fabric sails fluctuate in the air as if carried by the wind, finally resting on a web of wires that stretch between the buildings. The sails can be rolled up though a motorized system responding to climate condition.

Precipitation induced by cloud seeding

What is cloud seeding ?

Cloud seeding, a form of weather modification, is the attempt to change the amount or type of precipitation that falls from clouds, by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud.

Cloud seeding agents

1.Silver iodide is used as the glaciogenic (ice nucleating) seeding material because it has physical properties very similar to natural ice crystals

2. Indium (III) oxide is used as the inert tracer agent. The tracer particles are similar in size to the seeder particles; however they have no ice nucleating properties

Benefits of Cloud seeding

1.Artificially causing rain to facilitate habitation

2.Creating impact to reduce global warming

Cloud Seeding Process

QA_0710
Reference : SPERP Project report : CloudSeeding_

1. A comparatively dry and deserted area Anakie , in between Geelong and Ballarat is chosen as reference location

2. 30 km radius area is considered for the system operation

Site

Individual System Layout

• The cloud seeding to induce rain depends on the direction and speed

• The wind pattern in Anakie region is subjected to major change depending on the time of the year

• A network of flying drones is proposed instead of fixed generators as it can be repositioned considering the change in wind direction

• The major wind direction is North-South , during Apr,Aug-Oct. Hence a layput of cloud seeding drones is suggested considering this wind direction

• This layout will guide the pattern of vegetation grown in the forest.

Drones Individual System

• 23 pairs of flying drones are launched

• Two drones are located at each site: one to disperse seeding particle and another for tracing particle

• Each drone burns 1.25 litre / hour producing 20 grams of Silver Iodide and 11 grams of Indium Oxide particles

Criteria

• Freezing level of 1600m

• Cloud top temp. -7 degree C or cooler

• Cloud depth greater than or equal to 400m above -5 degree C level.

• At least 15 drones are targeting
