Institute of Heavens This project was produced during an exchange programme as a student in Arkitektskolen in Aarhus (AAA). This project deals with the framework ‘Relocation: The making of Utopia’ provided by the profound discourse Prof. Dr CJ Lim. The design studio focused on sustainability and refurbishment by bringing locations and buildings with a severe lack of future resilience back to contemporary standards and strengthen the link between the intervention and the city in the future. Under the guidance of Bartlett School of Architecture engineers, Simon Dickens and Mathew Wells, the project tries to implement contemporary building techniques and regulations to envision a local impermanent utopia. The following DR-report (design realisation report) brings things to the people which are outside of the conformist approach of architecture which is driven by those exact building codes and appliance of regulations. This Report was part of the eventual jury and the basis of the discussion during later design improvements.

It was part of an urban exhibition led by AAA called ‘Rising Architecture’ to celebrate the fact Aarhus was World Cultural Capital city of 2017. The final result was displayed on banners and posters in bus stops and in pavilions in Parks in Aarhus and Copenhagen during the summer of 2017 to revise the city of tomorrow.

The refurbishment and renewal of the current airport of Aarhus tries to elaborate the following: As all technological advances have contributed positively to our society’s growth and development, there should be an overwhelming reliance and a sense of disconnection with ‘the self’. By a process of physical and visual reconnection to regain a sense of believing in greater things in a hyper data-driven world. The airport, situated between heaven and ground is a good place to intensify this feeling. By trying to get rid of the sluggish procedures correlated with travelling via plane, the journey starts by commemorating all achievements connected to human exploration.

Without any aesthetic value but rather the appliance of intrinsic values, this place enables all passersby to connect and literary transcend on a higher level. Utilizing material storytelling and a playful approach towards spatial configurations as design tools, the transfer or sharing of knowledge allows us to build tangible emotional connections.

This design questions how multiple disrupting entities bring new life to the current airport as we know it. Currently, the airport has turned into a source of uncertainty. It is an undesirable place presenting a negative image on the economy and reputation of a city that works really hard to be present in Denmark, Europe and beyond. This project tries to find ways in which the old-fashioned existing structural rhythm can be intensified whilst new interventions symbolically enlarge the contrast between the old and the new, overthrowing the conventional functionality of this architectural generic typology.

Building Form, Systems Planning and Context

1.1 Introduction

1.1.1 Textual Rapprochement building form, context and system planning

Abstract of analysis: Pascal, the protagonist, is influenced by his own unavoidable personal past. He just so happens to be born in a very poor environment and can’t help to look at the world from a very narrow perspective, a view from a traumatised being. Only when he finally sees through the mistakes he made it is already too late. As he wanders into this uncertain void made by his own missteps he suddenly feels the need to write old friends about what his incentive aspirations for a better society are. It is only a short fragment in the prologue of the book that gives certain critique about the balance between order and disorder in our living environment that learned me how to look at ‘law in order’ in a very bright way but then, at the same time the writer overturns this concept two phrases later. Utopia = ‘Divinity’ Will be supervised by a godlike omniscient figure who assures that he, by the environment ‘he made’, repels all bad things people in chaotic settings like Utopia can come up with. The divine is being used as an instrument to conflict the ideas of those who think that the created order in a utopian system can easily be tackled. The orderly environment learns those people the power of ease, rhythm and peace in a lively and sunny setting.

Relocation = ‘ Curiosity and Immagination’ Those who wander around, work, travel and explore should have a hub that communicates the heavenly experience.To let them believe in greater endeavours, let them experience, feel and see stories they can bring to others while going to new horizons.

This ‘hub’ should be a homage to everything we link with the celestial. By making spaces that refer to all the great things humans made to get closer to heaven, the divine.

How can multiple disrupting entities bring new life to the current airport as we know it? Is there a way in which the old-fashioned and existing structural rhythm of the airport can be intensified as new interventions symbolically enlarge the contrast between old and new and overthrow the conventional functionality of this architectural typology?

Selected paragraph in ‘The family of Pascal Duarte’ Cela, Camilo José “Montaigne described ‘the order’ as a sad and gloomy virtue. Probably Montaigne confused this virtue with her mask, her outer appearance; which is common for orderly people, by those who don’t equate order to rhythm, but peace, and those, because they do not distinguish the demonic and the divine, end up mistaking roots for leaves. I believe ‘the order’ is cheerful, lively and sunny; and what’s sad, dead and dull is usually – in a deceitful and very emphatic manner - named order, whilst in reality it is nothing more than a void. The firmament is the prime example of order. While common ‘law and order’ is in most cases nothing but a tacit chaos forced to take over the bright colours of the order, although ultimately no one gets fooled by it.

1.1.3 Predesign and work leading up to the design building form, context and system planning

Plato: What we see can be beautiful because ‘they’ bring back memories.

The knowledge we get from things around us versus the knowledge of things how they really are.

The Idea-world: the things we pick up via our soul, come from the world that is perfect.

A painting in this world as real knowledge states it: is the idea of a painting we acknowledge being beautiful because it is connected with the idea of beauty.

Aristoteles: knowledge comes to us via multiple observations.

Knowledge comes from inside us, we decide what beauty is.

1.2 Planning

1.2.1 Master Plan, current airport building form, context and system planning

FOREST The Airport as a whole has a pretty good aircraft circulation system. There is lots of space for private small planes and a lot of facilities to place them in such as hangers. Other maintenance AIRFIELD/GRASS facilities are scattered around the plot and the overall connectivity between them seems to work. The focus of this project takes a closer look at the actual airport building.

HANGER MAINTENANCE FACILITIES AIRPORT BUILDING TERTIARY BUILDINGS

As we zoom in, we see that the airport building stands alone but consist of a multitude of different attached functional volumes. Maintenance facilities are placed on the left and right side of the airport building. On the left side, big hangers for private planes and maintenance work can be found and on the right side tertiary buildings related to the airport.

1.2.2 Master Plan, new airport footprint building form, context and system planning

The current airport is ‘planologically’ very complex for a building this size. It has some nice features such as a patio and a quite spacious entrance but overall it is a small disaster. Narrow pathways lead travellers to the airfield where they go outside to enter or exit the building. Office spaces and aitraffic control are placed on the second level. The exit is small and not very welcoming for arriving travelers. Retail is placed in the midle of the building and is badly connected in the circulation plan as a whole.

An early and rough estimation of the new airport footprint. is determined by offsetting the building plot lines of the current airport. To make a wider programmatic variety I the new building, I decided to include some of the functions in buildings adjacent to the airport. These buildings are maintenance facitlities.

Current occupancy rate is determined by the ‘European public building norm’ (NBN occupancy 10m2/pp/h) Around 150 people at the entrance and 140 people at the gate.

In 2016 : - 194 000 passengers within country - 158 000 passengers ouside of Denmark 70 m

- 30 000 Charter flights *cargo not included

200 m

= roughly 360 000 flight annually = roughly 928 people/day or 4 to 6 flight/day.

The new airport has a daily occupancy rate of 1500-1700 people.

In total this will bring the total amount of flight around 700 000 a year. This number can rise easily in the future as the new facilities will be Perfectly equipped to handle a daily amount of 8 to 10 flights.

All floors have their own compartment, starting from level 0 up the roof.

1.2 Compartments can’t be bigger then 3000 m2.

1.3 The height of each floor corresponds to the height of every compartment.

1.4 The walls and floors between compartments should have an El60 value. All

doors connecting the compartments are concrete slabs with steel support with

a minimum value of El60.

1.5 The walls of the kitchen require a resistance which is longer then 1h. The

doors to the kitchen have an Rf 1/2h value. The kitchen must have: Self-closing

doors El30 - Walls El 60 and a Minimum surface 2m2 1.6 Compartment calculation formula

can be exactly defined in m2 S’ = S-S”

S’ = S - S’’ S = 1456 m2 S’ = 0 m2 S’’ = 1456 m2

Amount of users Np = Nr + S’/3 Np = 485

The maximum evacuation distance of 45 m is violated. A second exit should be considered. Compartment 2. needs special regulations as the risk of fire is grater, the occupancy rate formula is therefore not applicable. Fire safety stairs/ladders must be added to construction.

evactuation 2.1 Evacuationroutes that have an occupation between 50 and 500

people should have 2 exits.

2.2 The exits must nd themselves in opposite areas of the compartment.

2.3 The compartments that are not on the evacuationlevel, should be

connected to this level by using stairs 2.4 maxium length of escape routes:

Because there’s only dayoccupation in this school:

- max 30m from the evacuation route (articulted route

connecting the stairs)

- max 45m from the nearest stairway or exit.

- max 80m from the acces of the second exit.

A proper rebar reinforcement needs to be considered as the load bearing walls are completely made out of concrete.

Due to a big span of 15 m in the departure hall and a span of 17 m in the terminal, reinforcement of the jointing between two constructional elements is necessary to reduce the bending moment and bring to load down safely whilst been detailed cleanly.

A regular wall construction is taken to show all material and constructional considerations of the airport refurbishment. This construction typology is seen in almost 70% of the building and is, therefore, t mentioning.

As seen above, in a disposition scheme of the reinforced rebar column jointing, the column is placed centrally on to the braces of the beam grid to ensure an absolute smooth ongoing concrete surface without dislocations. This is in order to let the beholder see very clearly the difference between the old and new structure.

By any means, no extra paint or ‘onlay’ is added, only bear and smooth-gray concrete columns in a fixed grid are placed on top of the concrete floor reaching for the concrete ceiling. This will make this space feel balanced.

2.3 Aristoteles: Construction and Detailing

2.3.1 Aristoteles, Brief Concept building construction

Upon arrival ‘Aristoteles’ seems majestic and elegant.

Curved shiny bent copper cladding surrounds the entire ceiling of this dome.

Its volume breaks trough the wall of the departure hall. This hall is all about the acknowledgement of the things we see in front of us. Flight and check-in information circles around planets spin continuously as the wind rotates them playfully. A giant clockface is projected on the ground and in the middle, a white surface brings live imagery of the surrounding area as people rotate a small dome on the roof of this hall. The white circle in the middle has the size of the moon compared to the diameter of the earth which is the diameter of Aristoteles in total.

Referring to one of the biggest landmarks in Aarhus, Aristotle’s will have interior and exterior copper cladding.

The camera obscura is the crown of Aristoteles, it allows people to see what they normally wouldnâ&#x20AC;&#x2122;t see. On a height of 27 m, this dome rotates and reflects incoming light to the ground in the in the entrance hall. A lens enlarges the view and shines light on a liquid silver mirror that is not adjustable. By pulling a cord, a cog mounted to the wheelbase of the rotating dome you can adjust the view.

So you can see a plane depart, a rabbit on the airstrip or maybe even the biggest landmarks in Aarhus City.

In order to let the camera obscura work, the glass roof on top of Aristoteles and 60% of the glass facade is tinted.

2.4.1 Plato A) Brief Concept building construction

â&#x20AC;&#x2DC;Platoâ&#x20AC;&#x2122; is, in essence, the beating hart of the new airport. An atrium, an open space to wander around and sit or lay down. A place to rest and wait, a welcoming chance to calm down for a moment and think about those you will soon meet again. Cut out of the concrete slabs an asymmetric cupola rises.

Bringing the look of those in the hall up, admiring broken down sunlight beams striking the ground.

You can see those you were waiting for on the other side of the windows arriving and travellers who depart in the terminal are treated with a spectacular view of the majestic beauty of a colourful mosaic on the

building construction 34

2.4.1 Plato B) Brief Concept building construction

“For he who would proceed aright... should begin in youth to visit beautiful forms... out of that he should create fair thoughts, and soon he will of himself perceive that the beauty of one form is akin to the beauty of another, and that beauty in every form is one and the same.” -Plato What we see can be beautiful because ‘they’ bring back memories.

The knowledge we get from things around us versus the knowledge of things how they really are.

The Idea-world: the things we pick up via our soul, come from the world that is perfect.

A painting in this world as real knowledge states it: is the idea of a painting we acknowledge being beautiful because it is connected with the idea of beauty.

At first, the beholder does not see why the tiles are coloured. He or she knows the ties are part of a bigger whole, a painting maybe, but it is just not visible yet.

Only from above, on the platforms of the terminal hall, a big mosaic painting reveals its beauty, seen from a distance, a new perspective.

2.5 Logical Reasoning: Construction and Detailing

2.5.1 Logic, Brief Concept building construction

â&#x20AC;&#x2DC;Logical Reasoningâ&#x20AC;&#x2122; is a place to celebrate human flight to the heavens.

Here people who wander or wait for their plane to depart admire the technical wonders of aircraft technology. A view of all angles of the plane is provided as spectators walk on the pathways suspended over the aircraft.

This maintenance facility is directly connected to the terminal with a wide glass door.

On top, nine big and brightly lighten boxes embrace the aircraft gently and provide symmetry and order to the whole.

first coinstruction detail sketch The whole construction of Logical reasoning rests on four points.

Big three by three-meter pillars suspend two long bolted or welded Vierendeel frames of 48m in length. Two other cantilevered Vierendeel frames are bolted on to the primary structure. This system allows the aircraft to park or ride in and out without needing to sacrifice more structural anchor points to the ground.

The dimensions of this frame are bases on both structural capabilities and the length and width of a large two motor aeroplane. Pathways or the frames are 3x3m and suspended to a height of 8m. The glass boxes on top are 22 mm high from the ground up. This is the total height of the back fin of a Boeing 787.

Logical Reasoning is generally an unheated space, an air tight facade and completely insulating facade is hereby not needed.

Though, a close connection of all building compartments is needed to ensure that all detailing is working the right way and no heating or water leaks occur in critical places.

A closer look at how the climate is regulated can be seen in chapter 3. With the implementation of a regulated heat system on demand, during winter times this construction can be heated locally if needed.

2.5.3 Logic, Structure A) building construction

Vierendeel frame, sketches and calculations

A vierendeel structure is the only load bearing construction that is able to span over 48 m on two points of support without losing any form of functionality. The beam, placed on top of two pillars is not only a load bearing structure, it also is a pathway for spectators to look at the plane parked under neath. The whole structure operates at a height of 8m, so a Boeing 757-800 (biggest plane possible) can be placed in the hanger.

2.6 Construction Sequence

2.6.1 Construction Seqeunce: old structure and new grid building construction

phase one: demolition existing airport and determining new plot

All attachments of the old building get demolished to make the new envelope as coherent as possible. A new outline of the plot gets determined and all necessary foundation for the new structure get cast. All rebars, disposition braces and steel placeholders get placed sol the new structure can be attached. The airport does not lose its functionality yet. All building functions are still covered by the existing roof and are enclosed with temporary interior walls.

phase two: further breakdown existing structure and attachment primary new structure.

On the fixed grid of steel braces, the new column and beam structure get cast. The aim is to make the transition between old and new structure as smooth as possible. The airport loses his functionality almost completely as the available covered spaces shrinks. Tents are placed on the outside of the building with their land- and airside functions in them. Exterior load bearing walls of the facade get casted and steel braces to carry the columns and beams for level 2 are prepared and placed. For 30 days big construction works are set aside to harden

*note, the rhythm of this construction sequence digram is determined by the startup and finishing of all wet construction elements involving the casting of concrete

2.6.2 Construction Seqeunce: slabs, walls and the three interventions get prepared building construction

phase three: casting of new concrete slabs and walls enclosing the old struc-

Concrete reinforced slabs get cast on top of the new building and along side the told old slabs. Large surfaces are still uncovered but the interior temporary walls are now replaced with permanent interior walls as portions of the airport functionality are placed within the building again. Columns and beams to carry the primary roof structure and exterior load bearing walls are cast. All braces and foundations are ready to start with the construction of Plato, Aristoteles and Logica Reasoning too. For another 30 days, big construction works are set aside to harden the concrete.

fase four: casting primary structure on level 1 & 2 and primary structure of Aristoteles & logic

The primary roof structure is placed on top of the hardened slabs on level 2. The ramp of the atrium Plato is made by digging the ground out and casting a new concrete lop-sided floor.

The primary steel structure of Logic gets delivered in small parts and is bolted and welded on site. The primary load-bearing steel columns of Aristoteles get delivered and placed. On site, the steel ring beams get welded together and bolted on to Aristotelesâ&#x20AC;&#x2122; primary structure.

building construction 46

2.6.3 Construction Seqeunce: finishing the three interventions and reintroduce all airport functions building construction

phase five: adding the primary structure of Plato, the secondary structure of logic and airport gates

The roof slabs get casted on top of the primary roof structure and all attatched volumes of terminal get finished. For another 30 days all big construction works are set aside to harden the concrete after which the construction of the envolope gets enrolled. The windows are placed and all interior finishing gets started. The airport functions get beack inside while still being airtight by the temporary interior walls where the construction can not be wind and water tight. The secundary structure of Logic gets delivered and bolted on site. The primary structure of Plato gets delivered and attached to the new concrete slabs and walls. The large cilendrical profiles get delivered and welded to the top ring beam on site.

fase 6: adding envelope of Aristoteles, Plato and Logic

The roof slabs get cast on top of the primary roof structure and all attached volumes of terminal get finished. For another 30 days, all big construction works are set aside to harden the concrete after which the construction of the envelope gets enrolled. The windows are placed and all interior finishing gets started. The airport functions get back inside while still being airtight by the temporary interior walls where the construction can not be wind and water tight. The secondary structure of Logic gets delivered and bolted on site. The primary structure of Plato gets delivered and attached to the new concrete slabs and walls. The large cylindrical profiles get delivered and welded to the top ring beam on site.

1.

Currently, people walk from the aircraft towards the entrance. Buffer zones are needed to keep the heat in at places where people enter the building.

In the entire airport, a floor-to-ceiling height of 3,8m is used. The low ceilings make the spaces cramped when lots of people are in it. The daylight factor is too low since the spaces are too deep. The existing grid, columns and beams can be reused to reduce the new building cost and construction waste of the demolition.

This is The only bright space in the existing airport. Overall, lots of artificial light is needed to make the interior more attractive. Note the grills, all spaces are currently mechanically ventilated and heated with air.

2.

The existing pathway to board the planes will be removed, it is too narrow unheated and feels draughty. Not an ideal place to wait when 200 people wait in line to board.

Outline/ footprint of the new building. The new building will respect the outer limits of the current plot and will use a more continuous and efficient envelope.

Staff rooms, offices, storage rooms will be removed. Offices will all remove to the second floor (existing volume, see plan level 2 ). Staff rooms will be moved to the core of the building and storage rooms will go to the basement.

The envelope will become more simple and the programme will be centralised which makes the whole building easier to heat up and maintain.

2. Boarding area, poeple are waiting in line to take their flight.

3. Check in area, a more welcoming space in the existing airport.

Although the airports as it is in its current state is only 15 years old, the existing building has lots of things to improve concerning renewable energy. Currently, a wide array of artificial or mechanical systems is used to ensure the interior climate- and comfort control. Too much-dimmed lighting and an inefficient way of heating and ventilation is applied. It is with this perspective that the refurbishment should aim for a maximal use of the present natural resources in the neighbourhood and really try to make use of the available space. Since the new building will be 30% larger, the demand will inevitably be higher. In order for this to work. A deeper look into the orientation and use of most forthcoming climate conditions leads the design into being more parametrically designed.

Incoming sunlight will have a large impact on the interior quality of the airport. Next, to openings in the front facade (airside) along the whole length of the terminal, the three interventions Plato, Aristotle and Logical Reasoning, will play a crucial role in letting natural sunlight enter the building. Note that incoming sun from the Southside, as displayed above, also means that there will be a lot of internal heat gain: direction incoming sun (E/y.) surface (m2) total

As the refurbishment of the old airport is mainly built on the existing structure, the vast majority of the building will have a flat roof. The flat roof is ideal to collect rainwater. The water that drains will be collected into a collector and send to a rainwater tank where is will serve multiple water utilities. The surplus water that is flooding from the rainwater tank will drain to a WADI with reed beds where it helps the groundwater level in good condition. All residual water is filtered in the beds will serve a second life as being used in the building utilities when water demand is high. Only after this, in a case of a flood, the water in the WADI will go to the sewage system.

1948 m2 0 kW T. = 3189 kW/y

All rainwater supplying roof surfaces will be covered with plants. The green roof serves multiple purposes. Its mass due to the â&#x20AC;&#x2DC;inertia-effectâ&#x20AC;&#x2122; will keep the building at a more constant temperature during summer and winter. More mass keeps the whole roof structure cool in summer time and warms in the summer time. The green roof will also serve as a buffer for all water that falls from the roof and will pre-filter the draining water. A green roof has a buffer volume of 35 l/m2.

A Strong wind of 13 m/s from the South-West can occur in the region of Jutland during 5% of the year. A not too gentle breeze of 6 m/s is very common.

In an open place such as an airfield, the building needs to make sure it can take full advantage of this local climate condition. For ventilation, the natural current will ensure a negative pressure on the North side of the building and is perfectly suitable for using natural ventilation extraction.

GREEN ROOF = buffer volume of 35 l/m suply area can be cut by half : 6821 m2 / 2 = 3410,5 m2 Rainwater tank can never be more empty then 5% of the time it is used. This, to prevent bacteria. But whit the high daily demand and a very large supplying surface, a maximum vacancy of 2 % are required.

Water overflow should always be considered, this to maintain the groundwater reserves.

Only the flat surfaces will provide the supplying rainwater drainage system. These surfaces can be covered with a ‘green roof’ and is easily be maintained.

Infiltration systems are needed for supplying surfaces larger than 250 m2

Total supplying roof surface = 6821 m2

Surface Filter coefficient greenroof 90 % Orientation South-West Consumption ( amount of devises X # People) # people Roofcovering coefficient 95% Inclinage 0%

= 3410,5 m2 = 0,9 = 1,25 = 98 = 1500 max daily = 0,95 =0

A pressure of 3 Bar on the supply line is needed when the water is demanded at 10m height.

The pump to ensure this to happen consumes roughly 0,6 kWh/m3 supplied water.

Supplying surface reduction factor: 3410,5 X 1,25 X 0,95 X 0,90 = 3644.9 m2 Consumption: ((98 X 1500)/ 3644,9)X100 = 4033 l/day/ 100m2 supplying surface Storage (with a maximum tank vacancy of 5%): (2X3644,9)/100 = 72 m3 or 72 000 m2 An underground storage tank of 70 000 litre will be needed to fulfill the need.

the heat pump will get its warm water from a drill pipe -170 m deep.

the heat pump will get its cold water from a drill pipe -105 m deep.

- Building cost each drill hole + installation 20 000€ or 148,800 D kr. Total cost = 45 000€ or 334 800 D kr.The payback period for replacing the old central heating system compered to electric costs is 8 years and heating costs is 5 years. Still, this is highly variable with the current energy prices and yearly climate differences. An additional time span of 20% of the total may be considered.

- The groundwater in the wells is so deep that it contains its warmth during the year until it gets pumped up again. Per 10m descend, ground temperature rises to 1°C. - The whole system is built out of more eco-friendly PE (polyethene) which has a lifespan of 250 years and is biodegradable since it is made out of natural components. PVC should never be used because it is proven to be harmfull and highly toxic when heated or burned.

-The total volume of groundwater that is stored and recovered in a year generally varies between 10 000 m3 and 150 000 m3 per well.

- The same system can be used to cool the building in summer as used to warm the building in summer.

Waiting lines can be long as more than 150 people are awaiting to be checked for immigration and luggage control before they get to the terminal. Interior quality control needs to be considered in every season as peoples clothing changes heavily security

terminal

The clothing index is different during all seasons. To reduce energy consumption, only at the gate where people are waiting to board the plane interior quality control are higher. Travellers are usually travelling with clothes and in the movement before coming to the gate so in the rest of the terminal normal temperature control is applied.

*note these are variable mininmum requiremments. More specific demand might be applied.

Typical interior comfort requirements in a public building:

20° to 23° C 300 LUX

The climate design of the airport is based on the special requirements of all individual parts of the building as the programme is very diverse. Secondly, the aim for this design is to reduce the over all energy demand. This is established by approaching the concept of comfort differently. Knowing that this public building has a lot of people on the move who have thicker clothing carrying with them, the overall interior climate comfort is reduced by several degrees, while still being within the temperature comfort zone.

3.6 Aristoteles, Conceptual Introduction: heating, lighting and ventilation performance strategy

general concept cross section

The entrance of the airport or â&#x20AC;&#x2DC;Aristotelesâ&#x20AC;&#x2122;, will be heated by cold air tunnelling trough a convector system which gets its warmth from the heat pump connected with the stored ground water.

Strong cross winds can power a giant wheel to spin and generate energy that is directly used to produce dimmed lighting in the enterance.

Ventilation of the whole west side of the building will happen trough the natural stacki effect of hot air. Thanks to its hight, this construction brings hot air to the top where it meets negative presure by South-West cross winds. In summer hot air escapes the building whilst in winter time, the hot air goâ&#x20AC;&#x2122;s back to the ground via ducts and gets tunneled to a heat exchanger.

The South facing facade is covered with PV solar panels to generate electricity and at the same time, create shading for the interior when ths sun strikes hardest.

Why only do a measurement during spring? During winter times the sun at 10° is too low to effect the centre and in summer the sun at 58° is high enough to be covered by the copper classed cap (roof) of the construction.

In the intermediate seasons incoming sun can not strike the centre where the camera obscura projection panel is located. Added sun shading is required.

3.7 Plato, Conceptual Introduction: heating, lighting and ventilation performance strategy

general concept cross section

The centre dome or Plato will be heated by cold air tunnelling trough a convector system on the wall or windows which will get there heath from the heat pump connected with the stored ground water.

Ventilation in this building compartment will happen trough the natural stacking effect of hot air. Thanks to its hight, this construction brings hot air to the top where it meets negative pressure by South-West cross winds. In summer hot air escapes the building whilst in winter time, the hot air goesâ&#x20AC;&#x2122;s back to the ground via ducts and gets tunnelled to a heat exchanger.

The South facing roof and a big part of the East facing roof are covered with PV solar panels that collect energy. At the same time, they create shading for the interior when the sun strikes hardest.

Energy goes to the batteries and gets stored during day time so it can provide energy when LED night lighting in the dome turns on. Surplus energy runs back to the net to counter clock the total energy consumption of the building.

The concept of providing shading and collecting energy at the same time is very attractive. However, the implementation of this system can be done very poorly.

It is important to make sure this concept improves the architectural concept and is not just placed loosely. * source: the Umbroza, Freshhome USA.

With the solar exposure study in mind, the PV- panels are spread unevenly on the places where the sun strikes hardest and where the shadow is certainly needed.

Given the fact that sunlight exposure on south facing roof tops delivers almost 90 kWh/ m2 per year and East the total South facing surfaces amounts to 160m2 it is worthed making a study on how many sun hours the West and East facing facade of ‘Plato’ are annually exposed to.

On a measurement of 2214 bright hours a year, only 203 hours have a potency above 90%. Lowering the efficiency of the solar gain exposure to around 68% we can still harvest a lot of the sun exposure on the East roof top facade as well.

South facing facade: 160x0,77 = 123m2 x 90 kWh/m2 =110,7 Wp/year East facing facade: 666x0,68= 452m2 X 60 kWh m2 = 273 Wp/year N * amount of cladded surface with PV-panels

The sun hours study proves that a system to block out the incoming sun on the floor in the interior can work. Incoming sun on the floor disturbs the efficiency of the floor heating system, as heat is no longer evenly distributed. That the sun shading can also provide electricity is only beneficial.

3.8 Logical Reasoning, Conceptual Introduction: heating, lighting and ventilation performance strategy

general concept cross section

â&#x20AC;&#x2DC;Logical Reasoningâ&#x20AC;&#x2122; is a space to reflect. It is structurally and constructively detached from the heated envelope and has a different interior climate.

As this compartment has a completely different programme from the rest of the building and is more exposed to the natural elements due to large transparent facades and a less airtight envelope, a different kind climate control is working here. Only centralized heating is working on specific places and there is a larger airflow as there are more openings to compensate for the large amount of solar exposure gains.

The South facing facades have a sunscreen behind the glass facade to block the incoming sun. Built up heat gets excavated by the natural stacking effect present in the volumes.

In summer the front facade (airside) is opened to let in fresh air. In wintertime, the facade closes up so it can be heated by the heating ceilings more easily if needed.

As this construction is completely transparent, lots of sun strikes the surfaces. to prevent the sun to strike to hard during summer, all facades on the South side are covered with a sun shield on the inside. This tensioned transparent textile veil blocks the sun almost completely and allows only indirect light to enter the maintenance workspace.

The structural concept of this maintenance hall is to keep the exterior facades as glassy, shiny and clean as possible. Though placing the sun shield on the inside of the construction is not ideal. The heat build up is much more present and to prevent any radiation heat behind this veil, it covers the complete surface.

Heated air can flow upwards and escape on the top where it is extracted by negative wind pressure.

The aluminium extruded extraction vent can open and close automatically with pneumatic pumps.

Temperature is measured close to the ground (1,5m) and on the top of the construction (22 m).

As soon as the measured temperature raises above the comfort level, the vents open an extract the air.

Due to toxic fumes from liquids in the air plane, by safety regulations, it is permitted that the highest air flow rate is applicable. occupancy rate= A/10 =2304 m2/10 = 230 persons max.

4.1 Stakeholders and Sponsors building delivery

Possible Sposors of ‘Instistute of Heavens’ Primarily, the stakeholders in this project will be the city of Aarhus and the aviation museum of Denmark in Aalborg. As The redevelopment of Aarhus with ‘Aarhus 2017, culture capital of Europe’ is trending at this very moment, the city tries its best to build up their image by building big buildings.

Needless to say, the current airport clearly isn’t on the list of buildings in the (re)development.

The upscaling of the city and ongoing appearance of building infrastructure is a good thing, and tourists come, next to travelling by train or bus, primarily by plane to Aarhus. Therefore the city of Aarhus should be the primary investor in this project. As a portal to its largely new and blooming city.

The close display of functioning aircraft or it mechanics and the celebration of the aeroplane as an invention that brought the masses closer to heaven is a fantastic thing.

Kids and their dads or hobbyists love it. Common aviation museums do exist and display great aircraft’s but none of them has functioning passenger aeroplanes to show.

The museum or multiple aviation museums in Denmark can be the sponsor of the maintenance hall with a possible collaboration of general commercial airlines such as the ones flying from or to Aarhus at the moment.

4.2 A letter to the Parliament building delivery

Friday 28 April 2017 KirkegĂĽrdsvej 10E, 4st. 8000 Aarhus C, Denmark

Sir Ole Birk Olesen Ministry of Transport, Building and Housing Frederiksholms Kanal 27 F 1220 Copenhagen K Dear Sir Birk Olesen,

Concerning the interconnection of the rural landscape and the growing city of Aarhus.

As a young, passionate and foreign architecture student I write you to express my concerns about a subject I am currently investigating on. A developing project named the â&#x20AC;&#x153;Institute of heavensâ&#x20AC;? can be viewed as an exercise in countering the ongoing problematics of relocating and re-inventing the Aarhus airport (Tirstrup Lufthaven).

Currently, the airport has turned into a source of uncertainty, an undesirable place presenting a negative image on the economy and reputation of a city that works really hard to be present in Denmark, Europe and beyond.

As the airport should be a hub for all connections with this city and the rest of the world, it is currently mightily underused whilst it should prove that Aarhus is indeed more than just a name on the map.

Therefore I think it is in the interest of Aarhus as a city to invest in this project in the near future. To reinsure that Aarhus is part of a bigger picture.

As an airport is seen as a largely private property I would love to see it being part of a larger discussion. One that tries to encounter how we look at an airport as being a public space that is owned by its stakeholders where Aarhus city should be one of.

Hope to hear your perspective on this matter.

Yours sincerely,

Elias Bey
