-IntroductionEmerging from earlier studies into performance based architecture the programme is for a theatre, housing the traditional Indonesian shadow art, Wayang Kulit. Sited in Java, the island most associated with this tradition,1 it is situated along the Citarum river, widely acknowledged as the most polluted river in the world.2 The river is a convergence of many current challenges facing Indonesia - the state of the river which

being a reflection of the rapid population growth, rapid industrialisation and extensive deforestation occurring in the archipelago.4 Taking this context into account the programme became a combination of the Javanese theatre and a water treatment

The purpose of a shadow theatre is both to entertain and to educate,5 and I intend to apply this mantra to the water treatment facility, the water travelling a highly choreographed procession around waterwheels and down waterfalls. This process will be driven by a wasteto-power plant, the idea of which is to encourage the local residents to dispose of waste here - currently it is the river which acts as a garbage disposal and sewer6,7 - and get clean water in return.

-Climate of West JavaIndonesia’s proximity to the equator and the fact that uniformly warm waters make up 81% of the archipelago’s area mean that there is little variation in temperature.1 The average mean temperature is 26-29˚C,2 with diurnal changes making very little impact on this figure - the city of Jakarta, also located in west Java, is known for having particularly high night-time temperatures of 25˚C.3 The real seasonal variations of the area are a result of the intertropical convergence zone, ITCZ, which dictates the rainy seasons and the two distinct prevailing winds.4 The ITCZ moves back and forth over the equator, creating a pattern where northerly winds dominate between November and March and southerly winds prevail between May to September, which is likely to impact any natural cooling strategies developed for the building. Also significant, is that as the weather system passes over the archipelago there are a few weeks in April and October which have very light winds,

active, having at least 12 recorded eruptions that have resulted in fatalities.2 The earthquakes that accompany the shifting tectonic plates will have to play a large part in dictating the structural logic of the building.

Project Site Merapi

The shaded orange areas in the diagram indicate places that the NHS has considered a high risk malaria zones.3 Though more common in urban areas, there is also the risk of dengue fever, for which there is no vaccine.4 This problem is particularly pertinent within my project, as it involves a large gathering of people at night (dusk till dawn is the peak activity time of a mosquito) in an illuminated structure above a freshwater river. Since most of the literature on avoiding mosquito bites advises to rid the vicinity of standing fresh water5 (impossible with both my programme and site) the architecture should offer an alternative. A house by Andrade Morettin Architects in Brazil offers one such possibility, having façades composed solely out of 50-foot-tall mosquito nets.6

This prevents

mosquitos entering and does little to encumber the passage of light and natural air currents. Other options could be to use light coloured finishes and grow citronella grass in the gardens, a tropical plant which naturally deters mosquitoes.7

The Selected Processes

The Citarum being slightly alkaline, pH 8.3,1 means it is necessary to provide space to mix in acid to neutralise it. This process is relatively quick and has no by-products. Hydrochloric acid

Coagulation Tank Here the chemicals aluminium sulphate and iron chloride are added to the water. They are mixed in and cause the solid particles in the water to clump together and sink to the bottom of the tank.2 The water pressure causes the cleaner water to be siphoned off at the top of the tank, and here I have taken the opportunity to create a waterfall feature out of the tank, as it is pushed out of the top and falls to the next stage of the process. This is potentially the most environmentally unfriendly aspect of the treatment as there are large amounts of ‘sludge’ drawn out at the bottom of the tanks. So as not to place the particles and waste chemicals back into the river, there is an option to dry out the waste and burn

Lagooning The ‘lagoons’ are constructed wetlands of reeds, where microbes living on the plants and their roots clean much smaller particles from the water.3 These are very environmentally friendly and unlike most aspects of a water treatment plant, their efficiency improves over time as the wetland becomes established.4 They are not often used in big plants as they require a lot of space, however the amount of water needed to be produced for the kampung is relatively small and the lagoons can form part of the landscape of gardens and waterfalls. Though slower than more industrial options, lagoons are popular in rural areas as they are very economical and their efficiency can be improved with the addition of bio-domes. These are equally economical, requiring only the amount of energy that is needed to power a 75watt bulb and can vastly improve the water turnover as they create ideal conditions between aerated layers of plastic for the microbes to grow. The lagoons can also make use of the algae fern, azolla, which can further purify the water, and, like most algae, is capable of dramatic growth, so that it will create a source of biofuel for the plant.

Filtration Filtration is the final stage of removing undissolved particles. Whist many plants incorporate sand filters I have chosen to use naturally porous lava rocks, which are used in the construction of the project and is locally available in this highly seismic region.

Electrodeionization Water is held in a tank with charged cathodes and anodes which remove dissolved metals that could not be removed by any level of filtration.5 This is a particularly important step here as the metals from the textile factories, mercury, lead, zinc and chrome, have very high levels here and are linked to cancer and organ damage.

Exchange process

UV treatment The final stage of treatment is to disinfect the water with ultraviolet light - the waves of radiation kill off the dissolved bacteria and viruses that are too small to be filtered out.6 There are other alternatives to this process which are cheaper such as adding chlorine,7 but these leave chemical residues in the drinking water and using UV lights offer the chance to enhance the gardens surrounding the theatre, as simply adding tonic water (which contains quinine) can make the flowers fluoresce under the lights. The tanks would have to be surrounded by glass that filters out any potentially harmful radiation.

Conditions:

As a tropical plant it should thrive in the local environment. It needs to be placed in full sun and provided with minimum of 30 inches of water per annum.

Indigenous to Java it should thrive here, however it tends to grow in the cooler mountainous regions so it should be placed out of the direct sunlight.

The night blooming cereus is a large white fragrant flower. Being white it has been placed near the UV gardens. The flowers go programmatically with the theatre, beginning to rapidly bloom at around 9pm (the time when performances start) and lasting only until dawn,2 it is often seen as a dramatic event.

Conditions: It requires a hot environment, so full sun should be fine, and as a cactus it needs to be kept dry, so the pots should have ample drainage to allow the plants to survive the rainfall of Java.

-Design Development-


-Indonesian Vernacular-

“There is staggering variety amongst the indigenous buildings... Something that unites many of them however are the features of being raised off the ground, and the presence of a large overhanging pitched roof.”

Creatures & floods

Rainfall

Ventilation

Being stylistically open-ended, most new buildings in tropical cities “adopt airconditioning as a panacea”1 However, with tropical countries poised to become world leaders in terms of economic and urban development,2 it seems imperative that new architecture in these places is equally forward thinking, creating a more sustainable typology for the tropics. In shaping a new environmental architecture, however, my project looked back to the archipelago’s rich vernacular tradition. This enabled many generations to inhabit the islands comfortably before the emergence and reliance on air conditioning.

My project aims to take these ancient forms as a starting point for an ecological architectureand drive this forward with the technological capabilities offered today.

There is staggering variety amongst the indigenous buildings, from the tongkonan, ancestral houses of the Toraja3 to the tiered pagodas of Bali. Something that unites many of them however are the features of being raised off the ground, on stone platforms or numerous wooden posts, and the presence of a large overhanging pitched roof. 4 The buildings being lifted off the ground is testament to the numerous wild snakes on the islands and a tendency to flood, whist the huge roof constructions not only provide a strategy to protect from the considerable rainfall but are also a means of natural ventilation, through the stack effect. My project aims to take these ancient forms as a starting point for an ecological architecture, and drive this forward with the technological capabilities offered today.

-Architectural Precedent-

Abu Dhabi Louvre- Jean Nouvel

The layered lace-like construction of Jean Nouvel’s Abu Dhabi Louvre is designed to mediate the harsh desert solar radiation and create an interior illuminated by a ‘rain of light’. Also positioned above a body of water, it has been calculated that the enormous metal canopy will amass vast quantities of condensation.1 My much smaller scale project can take advantage of other materials, for example layers of delicately carved wood which could, rather than be a surface to condense against, act rather as a sink for the humidity. Intricate patterns could serve my building similarly in reducing solar gain, and this aesthetic resonates with the largely Islamic cultural heritage of the island.
