History of Adaptation

The Consolidated Heritage of Greenwich Observatory

Contemporary Issues of Astronomy

Origins of the Observatory

City Light Pollution

Aiding sea travel and exploration through the study of astronomy, the Royal Observatory was built on the ruins of Greenwich Castle, due to its existing foundations, high ground and proximity to the Thames.

Due to the growing emission of artificial light pollution caused by the city’s growth, stargazing in London has been significantly harmed, with little to no star light visible at night.

The Observatory in Use

Community Engagement

The observatory underwent many various expansions and improvements through its life of use, becoming well established as the global lead in positional astronomy, with numerous discoveries and innovations.

As interest in astronomy has moved more towards the scientific and away from fantasy, general interest in stargazing and appreciation of star light has also diminished, with sites such as this no longer holding eminence.

The Repurposed Observatory

Relocation of Facilities

Issues with the Greenwich site were first identified in the 19th century, with increasing air and light pollution, resulting in the observatory being relocated and the site converted to museum and gallery spaces in 2007.

As cities have become less suited to astronomy, the relocation of scientific facilities has left historical observatories open to repurposing, albeit with a different focus that departs from the astronomy heritage.

Rise, Fall and Repurposing of the Royal Observatory, Greenwich The Royal Greenwich Observatory, contained within Greenwich Park, has the unique heritage as a leading site of astronomy for centuries. In modern times, however, it has been forced into adaptation that has brought less of a focus on astronomy, as public interest has been lost while stars have become hidden by the city lights.

Brexit Regulations for the Greenwich Cultural Hub of Astronomy A set of goals and guidelines to transform London into a city hub celebrating its heritage in astronomy, centred around the iconic and historic Royal Greenwich Observatory. These regulations aim to encourage the unity and betterment of the London community, once again placing London and Greenwich as the cultural centre of astronomy in Europe and the world. The precedent set through this masterplanning potentially can serve as example to be replicated and branched to more cities across the UK and throughout Europe.

Cultivating Community Engagement.

Re-Establishing Greenwich Observatory’s Eminence

i. Light pollution is a key inhibitor of star visibility at night, thus requiring various solutions for covering, reducing and eliminating its presence in London, in the form of both large scale, extravagant interventions.

i. Building a stronger community culture through localised celebrations of regularly occurring festival-like events, contributing to the shared responsibility and enthusiasm in making London’s night sky starrier.

i. Developing the Royal Greenwich Observatory and Greenwich Park as the focal point for this city of astronomy, becoming a place of pilgrimage during celestial events, attracting visitors from across the world.

ii. Implicating methods for controlling weather (i.e. clouds) during celestial events to ensure clarity of the night sky, providing these are ethical and non-harmful to humans and the environment.

ii. The coordination of extravagant festival displays within local areas across Greenwich Borough, emphasising this as the centre of the astronomy city and encouraging this sentiment in the borough’s residents.

ii. While the existing observatory buildings themselves are to be preserved, the surrounding park area and, specifically, the panoramic view point are to be used to site new facilities for public star gazing and amateur astronomy.

iii. Emphasis on the importance of proposals in being sustainably implicated and operated, further contributing to improved quality of living and viability of the project.

iii. The application of small scale light pollution interventions, distributed throughout communities for them to take part in ceremonious occasions.

iii. Outside of celestial events the park should also allow for public use in the eduction of astronomy and celestial bodies, through monumental constructs other publicly accessible facilities.

Chapter One

Creating the Perfect Night Sky The prevalent issue of light pollution is a key factor that has forced observatories across the UK and EU to relocate to more remote, rural areas, away from the cities and educational facilities that could benefit most from them. By putting in place regulations, devices and proposals that aim to clear light pollution, the public interest in the night sky may return again and allow London and Greenwich to return to its heritage in astronomy. Until a widespread culture against light pollution is fully grown, more abstract spectacles that bring attention back to the sky while reducing light pollution can be developed to gain public interest.

Conditions of Astronomy Researching into the general conditions that favour astronomy and have caused the abandonment of observatories in both the UK and EU to be located elsewhere. Then focusing on the astronomical conditions of Greenwich, in regards to charting the movement of stars and the moon to create a timeline of celestial events to be celebrated throughout a year. In developing this general understanding for the conditions required for astronomy, a more informed set of masterplan proposals can later be developed.

1. Jodrell Bank Observatory

2. Sherwood Observatory

Site - Part of the Jodrell Bank Centre for Astrophysics. Located south of Manchester, apart from any major city or town to minimise light pollution and other adverse conditions. Due to its lack of altitude (77m) it is reliant on high powered telescopes to operate.

Site - An amateur astronomical observatory primarily consisting of a publicly operated dome housing a single telescope. Its location on the outskirts of a town in Nottinghamshire are less than ideal due to the persistent light pollution of the area.

Equipment - The Lovell Telescope here is the world’s third largest steerable telescope, which is distinct in its appearance from common telescopes, likening more to that of a satellite dish.

Equipment - A 0.61m telescope with motor control is the only major piece of equipment here. A workshop is also on site for maintenance of this and other minor astronomical instruments.

Public - The site is host to many public activities and events, such as interactive astronomy sessions and a planetarium.

Public - The observatory includes amateur astronomy society gathering and lectures that are open to the public.

3. Radcliffe Observatory

4. Mills Observatory

Site - A former observatory part of Oxford University, operational from 1773 to 1934. Although originally suitable for use, the persistent increase in light pollution, adverse weather, and lack of facilities for expansion forced the University to relocate the astronomical instruments to South Africa.

Site - The UK’s first purpose built public astronomical observatory in Dundee, topped by one of the two remaining papier-mâché domes in the UK. It is located one mile from the city centre at the apex of the public park, sharing similar conditions to that of the Greenwich Observatory.

Equipment - The instruments of the observatory were relocated for museum displays once the observatory was decommissioned.

Equipment - It houses multiple small telescopes, up to 0.4m, of various capacities. Most commonly used are refracting telescopes used for public displays.

Public - As the site is now part of University campus it does not have any significant public presence.

5. Norman Lockyer Observatory

Public - The site is primarily used for public displays and activities, also including a domed planetarium.

6. Airdrie Public Observatory

3 Observatories Site - Formerly operated by Exeter University, now publicly accessible, the observatory is located a mile outside of the closest town, Sidemouth. The atmosphere is usually free of air and light pollution and the air is also free of rising currents, due to its proximity to the sea.

Site - The smallest fully operational public observatory in the UK, located in the centre of Airdrie. The building itself functions primarily as a library with the observatory located in the roof dome. Due to its town location, conditions for astronomy here are generally poor.

Equipment - Containing a variety of telescopes, the observatory is used for both radio and optical astronomy, with meteorology and weather satellite facilities as well as various others.

Equipment - A single 0.15m telescope of Victorian origin is used here, more so as a historic piece than for scientific purposes.

Public - The South West Astronomy Fair is hosted here every year for public participation in astronomy events.

Public - Although a small site, it is freely accessible to the public as an extension of the library facilities.

1. Sphinx Observatory

2. Haute-Provence Observatory

Site - Located on the Jungfraujoch in Switzerland and at an altitude of 3571m the Sphinx Observatory is the highest in Europe, albeit outside of the EU. Having been built in 1937 it is also one of the oldest modern observatories still in use.

Site - At a relatively low altitude of 650m, this site in France was chosen as an observatory for its consistency in favourable astronomical conditions, with an average of 60% of nights being suitable. However it is also prone to being disrupted by strong, cold winds (Mistrals).

Equipment - As a scientific station the observatory contains a 76cm telescope with Cassegrain and Coudé focus which, combined with its height, allows further and clearer astronomical observations.

Equipment - The observatory itself contains multiple telescopes ranging from 0.8m to 1.93m, including the original 0.8m telescope from 1932 which is required to be pointed manual.

Public - The site is also accessible to the public, with a viewing deck for the scenic mountain range and star gazing at night.

Public - The site and observatory have no public accessible features.

3. Pic Du Midi Observatory

4. La Specola Observatory

Site - Atop the French Pyrenees mountain range at 2877m altitude is the observatory established in 1878, the second oldest modern observatory in the world. Its altitude, proximity to the Greenwich meridian and isolation from towns cities provides excellent conditions for astronomical observations.

Site - A former observatory turned museum housed within a 14th Century tower converted for astronomical use in 1767. Although perhaps suitable for use originally, the development of the surrounding city, Padua, has rendered the site unsuitable due to heavy light pollution.

Equipment - There are multiple telescopes from 0.55m to 2m for astronomical observations, alongside more specialised equipment for solar studies, such as a photoelectric chronometer.

Equipment - No operational telescopes or scientific equipment remain here since the observatory’s decommission in the 1930s.

Public - A museum is located within one of the domes of the observatory and smaller telescopes are available for amateur astronomer use.

Public - The tower is now open to the public as a museum housing frescoes of famous astronomers and antique astronomical instruments.

5. Calar Alto Observatory

6. Roque de los Muchachos Observatory

Site - A series of dome structures housing telescopes on the Sierra de Los Filabres range in Spain, at an altitude of 2168m. The site’s height and sky clear of light pollution provides it with excellent conditions for astronomical observations. Equipment - The largest mainland European telescope of 3.5m is located here, as well as four smaller telescopes ranging 0.8m to 2.2m. Public - The site is also accessible to the public, with a viewing deck for the scenic mountain range and star gazing at night.

Site - On the island of La Palma in the Canary Islands, this site is known to be the second best for optical and infrared astronomy within the Northern Hemisphere. The island’s near perfect conditions are host to various international contributions, including the Isaac Newton Telescope from the Royal Greenwich Observatory.

EU States

Equipment - Many telescopes and observatories are located on the island, including the 10.4m Grand Telescope Canarias which has the world’s largest single aperture.

Celestial Sphere The Earth’s celestial sphere, used to chart the positions of stars, is comprised of axis formed by the extension of the North and South Poles and equator into space. Stars closer to the celestial poles appear to move in tighter circles in the sky compared to those near the celestial equator. Over the courses of a month and a year the constellations perform cyclical rotation, changing gradually as they move westward over time with the Earth’s orbit of the Sun.

The Celestial Sphere of Greenwich The progressive movement of constellations above Greenwich is constantly changing to the effect that any proposal would also need to provide adaptable facilities to follow this movement. Rather than following this constantly shifting movement, a programme may better be suited to more regular cycles and celestial events, such as moon cycles.

Greenwich Light Pollution Assessing the extent of light pollution present in the sky above Greenwich, which is vastly contributed to by the rest of London, most considerably by Canary Wharf. By using the summit of Greenwich Park as a base point, artificial lighting from the city is so much so that the skyglow created prevents any starlight to be observed without equipment. Any proposals for clearing light pollution would thus need to account for areas outside of Greenwich as well as those within.

Night Sky

City Lights

In London’s current state of light pollution, visibility of any constellations is considerably low. When coupled with cloudy weather conditions (as below) no starlight can be seen at all by the naked eye.

The view from Greenwich Observatory is presently a occupied by the illuminated cityscape of locations including Canary Wharf, Blackwall and the O2 Arena.

With the north facing direction of the view, the Moon is not visible most nights of the year - also having already set at the time of the photos - so is unlikely to be of significant concern in obscuring constellations.

The light conditions, present throughout the night, prevent any clear astronomical observations. The main contributors to this are the interior lightings from clusters of skyscrapers. The foreground buildings, however, are generally silhouetted and block some of the light.

The presence of the airport north of here also incurs distractions and light pollutants from the aircrafts traveling overhead.

However, the view also attracts small numbers of spectators each night - despite no features currently existing to facilitate this.

Festival of Balloons In the dual purpose of bringing public attention and interest in the sky and clearing light pollution, a Festival of Balloons would consist of various balloons and airships creating an extravagant spectacle in the sky in the day and leading into a celestial event at night. Leaning off of Archigram’s Instant City, a variety of airships would become covering that prevent light pollution reaching the sky, while also using devices for atmospheric monitoring and control to disperse cloud formations. These airship coverings would target the most heavily light polluting areas of London previously identified, while also dispersing smaller airships throughout the city to encourage people to take part in the festival.

Instant City Archigram’s balloon based concept to transport and assemble a kit of parts to become a cultural attraction. The balloons would theoretically arrive silently at night and remain for a week before moving on.

Balloons supporting a canvas over the area, as if under a circus tent.

Components would be delivered by airship before being separated and assembled.

Instant Cities would be temporary and dedicated to single events.

Instant Cities would arrive and act in stages of varying intensity and dispersal.

Celestial Event Balloon Festival

Balloon Cityscape Coverings Using a combination of light blocking, regulated light control and weather control to manipulate a improved astronomical sky while creating a public display bringing attention to the sky. Such solutions, based on Archigram’s Instant City, could include the use of hot air balloons and airships as mobile devices for obstructing light pollution, launched within Greenwich Park and throughout London.

Hot Air Balloon Inflation

Inflation Design Concepts

The ascension of hot air balloons is controlled via burners fixed to the basket. As they have no capacity to be steered, the direction of the balloons are determined entirely by wind conditions, unless it has been securely tethered to the ground.

Parachute valve

Horizontal load tapes Vertical load tapes

Balloons can also be launched with the assistance of vehicles or platforms that propel them forward upon reaching sufficient inflation, so as to match the speed and direction of the prevailing wind.

Envelope

Recreational hot air balloons are commonly inflated and launched without the aid of any structures, temporary or permanent, requiring sufficient ground and air space and having to do so starting on its side.

Hot Air Balloon Inflation and Manufacturing Although traditionally launched on its side, this poses a question of how hot air balloon launches may be eased for repeated use from a single location. Despite the various methods required, manufacturing can be located within a single facility, involving mostly assembly of pre-fabricated components and few specialist and isolated activities.

Solar Balloon Inflation Hydrogen burner

As the conductive black surface of the envelope is heated by the Sun, the air contained within becomes lighter that the air without, inflating the balloon.

PV current Hydrogen storage

The envelope fabric consists of an insulated double layer with an air gap to reduce heat escape and maintain inflation. This is aided by the shaded fabric’s interior being aluminium coated to minimise heat loss via radiation.

Laser Cloud Seeding

Energy generated from the PV panel cap is stored in a battery (or transfered to the ground via a cable) and used to generate a carried fuel cell.

Firing pulses of an infrared laser is used as an alternative to traditional cloud seeding via spreading silver iodide crystals.

Water tank

2. Ceiling Balloon

Due to their gas capacity, airships are able to lift heavy masses and can utilise propulsion and steering equipment unlike other balloons.

A small balloon, of approximately 40cm diameter, that is used by astrologists to calculate the height of the base of clouds from ground level during the day.

When the balloon is at a required height (for collateral safety) the laser is fired at cloud formations, clearing a particular portion of the sky for star gazing.

During the night, stored hydrogen can be combined with oxygen from the surrounding air to react and produce both electric current and water.

Aeronautic Balloon Typologies 1. Airship

In this experimental method, pulses of specific infrared wavelengths are fired at a desired region of clouds to strip electrons from atoms in the air, resulting in the formation of water droplets to disperse the clouds via rain.

The fuel cell uses electrolysis to decompose water, stored in a tank within the payload unit, into hydrogen (to be used) and air (to be released). The hydrogen gas is stored and used to fuel the backup burner.

Fuel cell Lightweight envelope and basket materials are used throughout to maximise the balloon’s effectiveness, with a backup burner included to maintain flight.

Chapter Two

Cultivating Community Engagement To maximise the effect of the sky celebrations to create a culture against light pollution, the issue must be approached on smaller, community scales as well as gaining wider attention. As a way of both allowing individuals and communities to engage in the sky festivals while reducing household light pollution, the distribution of light blocking devices enables this participation while they are also used productively. As a way of further developing a sky-centric culture, the use of balloons and airships can also be utilised as sustainably favourable alternatives to travel, both locally and internationally, to expand the project’s integration with the aim for a healthier world.

2.1

Light Festival Devices As a way to encourage community engagement in reducing light pollution during celestial events, festival-like celebrations are encouraged locally. Set place as the sun is setting, devices for covering light trespass and overlighting are distributed via airships, with the additional purpose of allowing light displays from the airships to be made more visible. After the sun has set and celebrations finished, the devices are kept in place to allow the celestial event to be more visible to everyone throughout the night.

“

The physiological effects of light at night and sleep disruption have been ‘proven’ in the sense that there is general acceptance in the scientific community of its truth; i.e. a consensus of experts. What has not been ‘proven’ is that electric light-at-night causally increases risk of cancer, or obesity, or diabetes, or depression. These connections are each plausible because many of the established physiological effects of circadian disruption and/ or disturbed sleep due to light at night are also implicated in disease pathogenesis; for example, cell-cycle regulation and DNA damage response for cancer, altered leptin and ghrelin for obesity, and loss of glycaemic control for diabetes.

”

Although blue light wavelengths (400-500nm) are necessary for alertness, memory and cognitive function, overexposure can lead to sleep deprivation due to over stimulation of the brain, as well as long term damage to eyesight. A maximum 480nm wavelength is produced by natural skylight, which fluctuates largely throughout a day, providing a healthy exposure that is intensified due to unfiltered artificial lighting.

Light Pollution’s Health Effects Artificial light contains constant blue light that is naturally only present at the sun’s peak, which causes harm to health by altering sleep patterns and weakens cell regeneration. By highlighting these factors to the city public it gives greater reason for larger community involvement in reducing light pollution beyond just astronomical clarity.

Greenwich Sky Masterplan A series of proposals throughout Greenwich intended to facilitate measures for reducing light pollution with airships, including public areas for festival displays, airship manufacturing and airship transport. The primary purpose for using airships being their use as a sustainable alternative for local and international transport, while causing little to no light pollution in their use and being able to carry devices to eliminated skyglow. Furthermore, the use of airships will bring about greater curiosity and attention to the sky, particularly as it turns to night and stars begin to appear.

International Star Chaser Port When fully realised, astronomy enthusiasts from across the world can gather to Greenwich as a central site of pilgrimage to admire the unpolluted night sky unseen in other cities. With this infrastructure Greenwich and London can again become a place of renown in astronomy, reintegrating the heritage of Greenwich Observatory in a culture that celebrates the sky.

Chapter Three

Re-Establishing Greenwich Observatory’s Eminence The focal point of the City of Stars masterplan, the heritage of astronomy in Greenwich Park is renewed and celebrated through the development of monument-like proposals in the Astronomy Park masterplan. Through these proposals, the public is encouraged to gain greater appreciation of both astronomy and the opportunities afforded by natural lighting - made possible through the reduced light pollution in Chapters One and Two. The project culminates in the central design of the park, the Moondial: a multi-purpose public timepiece that exhibits the experiential benefits of astronomy and natural light; provides spaces for amateur astronomers; and acts as a place of congregation during celestial events.

3.1 Site

Greenwich Park Greenwich Park has a long history associated with astronomy, with the Royal Observatory being located at the parks highest point and being a place of stargazing and study for centuries. Despite the Observatory still housing public exhibits relating to astronomy, it is no longer a functional site for stargazing. Instead the site remains a beacon of astronomy’s heritage, which can be appropriated within the project’s masterplan. With the vast area of the park being under heritage conservation, any proposals would have to be carefully considered in regards to their placement; not disturbing any heritage assets while adding to the park’s prominence.

Gyroscopic Telescope Mounts These towers are designed to provide more adept astronomers with precision stargazing, through the use of controllable gyroscopic telescope mounts that can follow celestial bodies and remain stable. To aid ease of use, telescope and equipment can be sent to the observation chamber via a lift pod extruded from the centre of the tower to ground level, becoming a table when in the chamber.

Precision Star Gazing Using the gyroscopic tower’s frame mount an astronomer is able to affix their telescope and equipment for star gazing, which remains in a fixed central position as it rotates. This allows the astronomer view at a 90° radius of the sky above while remaining clear of disturbances and without altering their setup.

The Moondial

The central focus of the masterplan, the Moondial is a monument to the night sky, being a timekeeping piece that provides unique views of the sky, both in unobscured chamber spaces and reflective surfaces to see the stars from different perspectives. The Moondial has the dual programme of providing space and facilities for amateur astronomers to congregate, while also being a symbiotic example to the public of the benefits of natural light as opposed to artificial. The forms of the Moondial develop to become more inclusive with the landscape, with the namesake dish appearing to emerge from the ground and merge with the night sky, in a curved form intended to evoke imagery of the waning moon.

Designing By Moonlight By taking into account the changing position of the Moon in the night sky, a design can be formed to optimise how it is viewed and followed. The rows of rotating compass lines indicated the nightly adjustments required to read a Moondial, as shadows cast by the Moon change by 12° each night over a synodic month.

Reflecting The Starlit Sky The face of the Moondial gives a second perspective of the night sky, reflecting starlight so it can be seen below as well as above. This is given greater effect with the dial appearing as if floating above the dark ground below it, making it appear as if a celestial body itself.

3.4 Journey Into Light

Guiding Through Phenomenology In moving the Moondial’s design focus away from framing the Moon cycle and instead onto creating an experience of natural light, it has become a design more in line with the experiential qualities of phenomenology. Visitors are encouraged to journey into the subterranean Moondial after seeing and hearing glimpses from ground level, leading them into spaces where light interacts with water to become a guiding experience leading into a central cave-like celestial space. In this main chamber, dominated by a waterfall wall, light from the dish’s aperture is cast onto the splashing water and mist to create sparkling light for visitors to walk through, as if they are walking through star light.

Subterranean Dark Spaces - Section AA

Cascading Pools, Perge

Salk Institute, Louis Khan

Makomanai Takino Cemetery, Tadao Ando

Built by the ancient Romans and unique to this site, this ground level aqueduct system uses a series of shallow pools along a declining street as both a practical and aesthetic feature. As one pool overfills it spills into the next, maintaining a constant level in each pool while also a constant flow of water.

The abundance of natural lighting and wide pathway bisected by a thin channel of water set a scene intentionally aligned with the setting of the sun; an event instance occurring daily and seen in a view framed by the architecture. This water becomes the central guiding feature of the design during these times of day.

Built to give greater appreciation to the existing Buddha statue by showing a glimpse of the statue’s head at a distance at ground level, building anticipation as visitors must proceed through an unlit corridor to reach the Buddha, at which point it appears framed by the circle of sky above.

Subterranean Dark Spaces Visitors at ground level see the aperture of the Moondial dish and hear the waterfall as a glimpse of what is below, drawing them to enter the unfamiliar darkness of the subterranean entrance. As they proceed into the darkness and visitors’ eyesight adapts slightly, when turning the corner to the main chamber it appears briefly brighter, with the glistening light on the water becoming more apparent.

Prague Astronomical Clock A clock consisting of three parts as a timekeeping piece for celestial bodies: the Astronomical Dial, the Walk of the Apostel Figurines and the Zodiac Dial. It is used by astronomers to find the position of stars.

St. Rita Church, Leon Stynen and Paul de Meyer A cathedral in the style of subtle brutalism, light is channeled from an aperture in the roof to the congregation below. The form of the walls leads the observer to look upwards in following the vertical furrows.

Astronomers’ Pilgrimage To make the waterfall chamber a place of nightly pilgrimage for astronomers, an astronomical clock provides them with the positioning of the Moon and stars in the sky on that night, while being an educational curiosity to regular visitors. After undertaking the experiential journey of light to reach this clock, astronomers can then proceed through to star gaze after leaving, with a greater appreciation of the stars and their movement.

Guiding Light In developing the experience of the journey into the earth, the addition of a light aperture running directly above the cascading pools should cause greater effect in creating a stronger contrast with light and shadows. As light is cast onto the pools they are brought more into focus, causing the textured handrails, walls and distant turns to become hidden in darkness, making the necessity for touch more important in guiding visitors through as they light shows a general direction.

Materiality Experimentation Models As light interacts with the surface material of the corridor, depending on the surface finish and pigment, it will either multiply or diminish - the desired effect being that surfaces are made visible only in direct light. This too applies to the textured handrail, being a tactile material that visitors can run their hands over to guide through the dark, without being overtly visible.

125mm 1:5

Handrail Textures In Darkness Using the prior model experiments, these textures create varying effectiveness in both how they are seen in darkness and the roughness of the texture against a hand. The central model balances these two qualities the most effectively; being clearly pronounced but not too course, and with a matt finish that casts some shadow giving hint to its presence.

3.5 Journey’s End

Egress of Water and Stars As the entryway and main chamber no longer focus on framing views of the sky in favour of an experiential journey, the transition from the immersive atmosphere of the waterfall to the world outside is made to be a more calming journey that includes these views. After leaving the waterfall and diverging on two separate but identical paths, lending to more private experiences, visitors enter spaces where the sky above is the sole focus in an enclosed space isolated from the noise outside. When reaching ground level, the presence of water re-emerges, now using its reflective properties to give changing perspective of the sky as visitors see it from changing angles. This inhabitable water feature then merges with the park and cafe to become a general use space for the public.

The pool containing still water on a dark base creates a reflective quality the shows an almost undisturbed image when viewed at the right angle. The project also uses cork lining to insulate an otherwise expose environment.

The Water Temple is designed around a sensory experience that first gives glimpses of the structure through the plants and trees before arriving at the labyrinth within.

Testing Water Pool Reflections

In these simple tests, the reflective properties of water is being examined at different angles, corresponding to the changing angles of view when visitors exit parallel to the circular reflecting pool. Also being examined is the replication of space photography that has been edited with colour, seeing if colour added to water would in any way inhibit or benefit the reflected imagery.

While the image reflection is still visible, it is less so due to a reduced surface area.

Water Run-Off Textures Texture i A datum model to observe water flow on a flat surface; an even distribution with a slight reflection.

Texture ii

Curving parallel ridges; causing a cascading effect when horizontal but limiting the spread of water when also vertical.

Texture iii

Offsets of curved ridges; causing water to either gather in or away from the edge’s center with a slightly rippled effect.

Texture iv

An inverse of the previous model; a contrast of water gathering in the ridges or not flowing into them.

Stepped Waterfall Pools

Texture v

A surface of gridded indentations; creates air pockets and a sparkling effect that compliments the reflections of forming bubbles.

Texture vi

A uniformly pocked texture surface; water run-off ripples the most here, creating instances of rippled light reflections and forming bubbles.

Texture vii

A surface of parallel ridges; when at a slighter incline water tends to run along the ridges; when steeper water becoming more active and rippled.

Texture viii

Rows of similar circular extrusions; water runs between the circles, as if islands amongst a reflective pool, becoming submerged when steeper.

Egress Of Textured Water Flow These chosen surface textures appropriately create a developing flow of water, from calm to rough, as it approaches the culmination of its journey along with that of the observing visitors. The water transitions from the calm pool to a slightly rougher flow, that becomes even more so as water ripples and bubbles before beginning to disappear between raised extrusions

Aviary Adaptation In the event that the Moondial becomes unused and redundant, rather than demolition it has the potential to use its water infrastructure and semi-enclosed internal spaces as an aviary sanctuary. This would require minimal alteration and would still allow the site to remain functional for the public to journey through.

Light aperture channeling into the staircase exit 4. Sliding glass doors that enclose the space between here and the waterfall 5. A glass canopy coving the exit passage, tinted grey to darken the sky and put focus on the water 6. Declining exit passage that changes the angle view of the water as visitors leave 7. Clear glass skylights to the Night Sky Outlook spaces below 8. 400mm stepped seating for amateur astronomers and stargazers to rest 9. Water flowing from the main pool into the moats surrounding the Astronomer Spheres 10. The Astronomer Spheres used for more precise and private star gazing 11. Patterned water flow running from smooth to rough as visitors reach the end of their journey 12. Water appears to disappear into the ground, falling into a gap that circulates water back

Overview of the Moondial Egress When visitors leave the Moondial they are given differing perspectives of the sky by looking in each direction, seeing reflections on water and a monochromatic sky above. After leaving this space can still be used as a general feature of the park; used as seating and a water feature for the adjoining cafe during the day and as a place for amateur astronomers to set up their telescopes at night.

Sustainable Water Circulation Water used for the various features of the Moondial is collected via rainwater and a secondary borehole pump, taking no water from the city’s infrastructure. Water is cycled through the building continuously, being filtered and treated to ensure it is clean, with storage for excess capacity.

Rainwater Collection and Pools The tiles of the Moondial’s dish are used both as reflective surfaces and for rain water collection, using the inclined surface to channel water into gaps at the dish’s base. This water is then filtered in a temporary overflow tank before being circulated through the structure, including a constant flow along the central cascading pools.

3.6 Concluding Proposal

In a Sky of a Million Stars The central focus of the masterplan, the Moondial is a monument to the night sky, being a timekeeping piece that provides unique views of the sky, both in unobscured chamber spaces and reflective surfaces to see the stars from different perspectives. The Moondial has the dual programme of providing space and facilities for amateur astronomers to congregate, while also being a symbiotic example to the public of the benefits of natural light as opposed to artificial. The forms of the Moondial develop to become more inclusive with the landscape, with the namesake dish appearing to emerge from the ground and merge with the night sky, in a curved form intended to evoke imagery of the waning moon.
