The tale of Yggdrasil

“In the middle of Asgard, where the Gods and Goddesses lives, is Yggdrasil. Yggdrasil is the tree of life, and it is an eternal green Ash tree; the branches stretch out over all of the nine worlds in Norse mythology, and extend up and above the heavens. Yggdrasil is carried by three enormous roots, the first root from Yggdrasil is in Asgard, the home of the Gods it is just next to the well-named Urd, this is where the Gods and Goddesses have their daily meetings.�

Forestry Genetic Research In over a century of forestry in Iceland, Project Yggdrasil has prevented the destruction of the last remnants of natural forests. The project has enabled the education and research to further develop Icelandic tree populations with results positively showing tree growth in areas once thought impossible to grow upon. The institute is proud to house all the northern hemisphere tree population and is at the forefront of Boreal forest genetics internationally. The benefits of this research is being exercised globally. Without a doubt, the most important outcome of Yggdrasil’s in the past 10 years is the slow realisation among the Icelandic people that

we can actually grow forests and reap the resulting benefits.

A century ago, most Icelanders had never even seen a tree, planting trees was the harmless hobby of a few eccentrics. Today, forestry for timber production, land reclamation and amenity is being carried out by thousands of people all over Iceland. Growing forests are both an outcome of and cause for optimism for the re-forestation across the country. What once started as an idea as part of the change of identity in Reykjavik, project Yggdrasil has resulted in a seed for change across Iceland and the world.

A BARREN LANDSCAPE A Treeless landscape

‘A century ago, most Icelanders had never seen a tree. Fifty years ago, few Icelanders believed that trees of any size to speak of could grow in Iceland. Planting trees was the harmless hobby of a few eccentrics, but forests for timber production were out of the question.’ Thröstur Eysteinsson (Director of the Icelandic Forest Service.)

From the days of the first settlers, Iceland suffered arguably the most dramatic levels of deforestation in recent history. Geological exploration and the melting of Glaciers has led scientists to find samples of trees which has led the scientific community to belive that 1500 years ago over 40% of the country was covered in trees. However, because of the unstable logging (from lack of education) this number is said to have reached 1.9% in the year 2018. This catastrophic example of deforestation has been further exemplified by rising temperature levels meaning that any of the native species which survived would no longer grow resulting in the vast, barren landscape which has become synonymous with Iceland today.

AD 879 40% of tree coverage

However, recent research suggests that the impact of climate change on increasing temperature, rising water levels and increasing ambient carbon dioxide concentration all show that Iceland is soon to become a hospitable location for tree growth which has been capitalised through various re-forestation efforts around the country. Project Yggdrasil aims to be at the heart of it.

ECONOMIC IMPLICATIONS A country reliant on imports

99.8%

of Icelandic construction timber is imported

Eruptions over the ensuing centuries from some of Iceland’s many volcanoes deposited thick layers of volcanic material. The ash, while rich in nutrients, made for very fragile, poor soil that couldn’t hold water and moved around as the wind blew resulting in difficulties in forestry.

The investment in tree growth research in Iceland could provide a huge platform for the Icelandic economy. Currently, due to low forest density, there is little room for timber production for the construction industry and therefore it accounts for a large import into the country.

There have been efforts in the recent years to create construction timber through the Hrymur project which has enabled a certain sector of small residential extensions to use the materials. However, the Icelandic housing boom in Reykjavik and the continued need for houses creates a market for Icelandic timber.

19% £900million

Iceland’s vast energy stores can we used in the production and with the research from project Yggdrasil, potentially could create a system of high preforming timber to specifications suitable for the building regulations in the city. Currently the country imports £900million of timber a year. Not only is this a large financial burden on construction projects resulting in higher build costs, it also has implications on Iceland’s oil use and C02 emissions.

“Boreal forests hold up to 44% of Earth’s land based carbons.”

NEED FOR TREES A degrading ecosystem

The future health of the planet depends heavily on one vast ring of trees: the boreal forest, which spans nearly the entire globe just below the Arctic Circle.

In addition to being one of the world’s greatest remaining stretches of wilderness, home to many vulnerable species, the forest stores an enormous amount of carbon. Some experts calculate that the boreal holds about 44 percent of earth’s land-based carbon. Upsetting that ecosystem and casting that carbon back into the atmosphere would undermine efforts to limit global warming. Bottom line: Keeping the boreal intact is crucial to the fight against climate change.

“600m2 of Boreal forests absorb enough CO2 to offset the emissions of 24million cars per year.”

20

Despite the widespread use of geothermal energy and hydropower, Iceland has high per-capita emissions of greenhouse gases, largely because of transportation and heavy industries like aluminum smelting. The government is working with the European Union and Norway to meet an overall goal of a 40 percent emissions reduction from 1990 levels by 2030. Separately, Iceland has its own target of a reduction between 50 percent and 75 percent by 2050.

Trees, by incorporating atmospheric carbon dioxide into their trunks, roots and other tissues, can offset some of the country’s emissions.

GENETIC BREEDING A tree filled future?

Breeding programmes are ongoing and seed orchards have established in Iceland as in most other countries with organised forestry. The decision was made in 2006 to change direction in larch breeding in Iceland. Emphasis was placed on producing the European x Siberian larch hybrid using parents selected in Iceland.

An LED growing house in Iceland

It started in 1993 with the aim of breeding Siberian larch (Larix sibirica / Larix sukaczewii) to be better adapted to Icelandic conditions. Included in the original selections was a clone of European larch, and controlled crosses were made between that clone and several Siberian larch clones. Progeny trials soon revealed that the hybrid outgrew all Siberian larch families, especially in volume, and had much better form than European larch generally shows in Iceland. The advantage of the hybrid over both parental species in growth and adaptation to Icelandic conditions has since become increasingly obvious over the years. Since the mid-1990s, the climate has been warming, which in Iceland mostly means milder winters, exactly the climatic factor that Siberian larch has limited adaptation to deal with.

CLIENT & BRIEF A collaborative approach

EUFORGEN – the European Forest Genetic Resources Programme – is an international cooperation programme that promotes the conservation and sustainable use of forest genetic resources in Europe as an integral part of sustainable forest management. Already working with the European forestry commission and the Icelandic government they require a base for their research which will have global appeal- Project Yggdrasil, Reykjavik.

Client

Research

Being the main stakeholder in the project Euforgen will gain invaluable research expertise from the University of Iceland acting a research partner with the institute. The regional and national impact of the project will benefit both local and national government whilst the nature of the building provides a public asset the municipality of Reykjavik which can integrate within the city. The research provided by the project against boreal forest degradation, as well as research into European species will be governed by the European forestry commission and the Food and Agriculture Organization of the United Nations. Although EUFORGEN are acting as the principle client of the project and therefore own all intellectual property of the institute the collaboration of all party’s will have a local, national and international benefits.

A CONNECTED BUILDING Creating links in the world Icelandic impact

The Project Yggdrasil institute will have significant global values. The overall aim of the project is to provide the research and facilities to re-plant Iceland and provide a platform to reduce Boreal forest degradation globally. Yggdrasil will work at three scales providing a key purpose to each.

The first will be the immediate local scale and will provide Reykjavik a building which acts as a catalyst for change in the landscape tying into the 101 masterplan. Secondly, it will have national value having outreach projects across Iceland to further test and explore tree growth. Finally, people will travel from all over the world to learn from Yggdrasil and the building will act as a seed for change for forestry internationally.

COLLABORATION A collaborative approach Not only does the site act as central node to the rest of the 101 locale, it has a defining position in the existing Hólavallagarður park and the new winter park. The combination of the two parks creates the sqm needed for the research at the institute and creates the opportunity for exploration in the trees which can also be engaged by the public within the parks. In order for the program to be successful it is important that all aspects have input to the site. The location of project Yggdrasil has been positioned in the site so that it has the best opportunity to be a successful addition to the city. The key connections of the site are as follows: Icelandic government -Provides the authoritative connection of the site to the wider context of Iceland and the world.

YGGDRASIL ARBORETUM A greener Iceland.

Extract from Project Yggdrasil launching website: Opening in spring 2021, Project Yggdrasil is the new national arboretum and Iceland’s centre for tree research and development which is integral for the future health of the country’s forests. The arboretum will contain over 25Hectres (10,000+ trees!) of new tree species used in reforest across the whole of Iceland. In the park you will be able to experience all sorts of activities and trail routes where you can learn what is happening in the battle to make our country green again.

ICELAND An isolated island off Europe

Iceland is not just a sprawling vista of untouched majesty. It’s a place with the population of a small town—338,000 people—that’s an actual country.

It’s a battlefield hosting a centuries-long battles between fire and ice, where unpredictable weather makes it seem like three seasons have passed in the course of four minutes.

Iceland is an island, a European country, located midway between North America and mainland Europe lying just below the Arctic Circle between 64 and 66 degrees north. Its capital city- Reykjavik is the northernmost capital in the world, located exactly halfway between New York and Moscow. It’s location on the Mid Atlantic ridge (the largest tectonic plate boundary in the Northern hemisphere) has created a unique environment which is enhanced by the countries position on the north of the Gulf stream bringing warm air to break the Arctic climate providing temperate weather allowing for the settlement of Iceland.

SITE In the heart of the 101

101 is the heart, soul and centre of Reykjavik. It is the area of the city which was first settled and is the connection of all political, social, economical and recreational activities of the city and Iceland. Its position in the North of the city means it benefits from protection from the Greenland sea due to the Reykjavik fjord forming a bay which the city spreads out along.

REPLANTING REYKJAVIK Masterplan proposal

The masterplan aims to plant a total of 46,750 trees in the 101 zone across the summer coast, winter park and harbour, acting as a means of improving air quality in the city.

Increase in the number of tree’s in Reykjavik Centre.

Reykjavik currently emits around 2.8 CO2 tons per person per year (2013), with a population of around 123,000 that equates to total of 343,000 CO2 tons per year. Trees at their most productive rate can absorb 0.18 tons per year, therefore planting 46,750 in the 101 alone can aborbs 2.5% of the cities emissions.

By varying the density across these three areas, we can create differing environments to suite the areas purpose and programme. For example, the trees along the summer coast are densly populated to provide protection from the wind; whereas around the harbour it’s scarce to encourage interaction with the water.

EXISTING TYPOLOGY Reykjavik’s history of architecture

The result of the 1960’s masterplan meant that many of the roads are given over to the use of the car, and therefore lack identity. The typology of Reykjavik has started to change over the past decade, however it is still dominated with the typical Icelandic form shown on the opposite page, a derivative of the old turf houses.

Corrugated iron dominates the streets-in Reykjavik.

Most often utilised solely for industrial purposes— such as to build sheds, storages or barns—in Iceland, the material proved so ideal for the local weather that it got embraced by the nation as a whole, allowing it to develop aesthetically. For instance, while the iron plates of such houses are elsewhere applied horizontally, in Iceland they are vertical, making them better suited for fending off rain and salt.

SITE CONDITIONS Key components of the site

The site is bound by both existing context and the new winter park to be completed in the Reykjavik ‘City of light’ masterplan. This creates design issues for a building which responds to both contexts, however the opportunity to explore ideas in both parts of the parks will be addressed in the design process with design inspiration being drawn from both the immediate locale to the wider conditions of Iceland.

Contextually the site has three major conditions.

Firstly, the park edge is lined with the traditional Reykjavik archetype. This strong boundary creates scale to the edge of the site and provides opportunity for development of form to create a building which

is holistically design with its landscape. Secondly the landscape of the park provides a natural setting

which can inspire the form of the building. There is a particular importance for the connection the building lakes with the existing and new context in the park. Finally is the sites position to the lake.

There are potential view opportunities whilst also constraints on the construction.

The environmental context of the site is largely driven by the light. Because of the duality of sunlight in the city between winter and summer, the building has to address different lighting conditions, particularly important for the efficiency of the growth of trees.

YGGRDASIL ARBORETUM Reykjavik’s new park

Welcome to Yggdrasil arboretum, Iceland’s new national centre of trees. Located in Reykjavik’s Hljómskálagarðurinn park this 26 acre arboretum accommodates all the tree species used in the reforestation of Iceland. At the heart of the park sits the pair of buildings which create a gateway to the park forming the start of the various trail routes around Yggdrasil. The two buildings consist of: The research building Located adjacent to the road the building houses the brains of the arboretum, accommodating 12 labs and LED growing facilities the building provides all the research needed for the re-forestation of the park and Iceland.

The growth building The arboretums jewel in the landscape, the growth building houses 13 growing bays which monitor and exhibit new and existing species of tree for the public to enjoy and interact with.

CONCEPT OF THE DESIGN

Mirrored proportions

Creating meaning on the site Continuity to street

Learn

The two buildings are derived from three design concepts in the park which will allows the architecture to become engrained in the typology of Hljómskálagarðurinn park, Reykjavik and Iceland.

Continuity to street Reykjavik’s typical typology is a result of the cities young planning strategy. Yggrdasil aims to adopt this typology to create strong links to the place and create a ‘typical’ piece of architecture to Iceland which had a very un-typical function.

Grow

A pair of twins Reykjavik is a city of duality. Iceland’s position just below the arctic circle means that summer creates almost endless light and winter endless dark. The buildings materiality and form aim to mirror this duality creating a pair of twins in the landscape, two buildings which have a direct relationship to each other.

MASSING Sitting the buildings on the site

Following massing exploration of the buildings key design decisions were made in the way that two buildings interacted with the site. A distinct hierarchy was established, the research building was private and the growth building public with the two buildings being tied together with a shared landscape and courtyard. The arrival to the buildings is the only time the two buildings meet creating slight tension and increasing the prominence of a gateway.

Linear architecture creates problems with the how the buildings end, however Yggdrasil has highly functional ends creating a linking between inputs and outputs to the buildings in the form of people, knowledge or trees.

INTEGRATION TO SITE How the buildings sit in the park

Project Yggdrasil uses its architectural design as a response to site specific issues such as wind, solar control, topography and access. The buildings also use the huge advantages of the site to further improve its place in Reykjavik. It does this in three ways: Functionality- Using the large park to extend the growth of trees and the arboretums ability to act as a nursery in the production of trees for Iceland.

Connectivity- Being located close to a new major transportation hub for Reykjavik as part of the 101 masterplan allows for greater and more efficient connections to the region and Iceland.

Accessibility- The sites location in the centre of Reykjavik allows for access for all people through sustainable modes. There is an already well established identity with the park which has been utilized to improve the buildings future success upon completion and handover.

The research building is organised based on scales of human activity and need for light. The building will get progressively busier with people are you move up the three floors which have been categorised as: Grow (ground floor) Test (first floor) and Learn (second floor). Icelandâ&#x20AC;&#x2122;s low sun means that light at ground level is sparse because of overshadowing therefore the majority of experiential spaces which are used by people such as the classrooms and meeting spaces will be higher up the building offering views out of the arboretum and less risk of overshadow.

The growth building is fundamentally for the monitoring and exhibition of trees giving users a various vantage points through the use of a mezzanine level 4 meters above ground.

CONNECTING ARCHITECTURE Strong links in the city

Project Yggdrasil

Reykjavik Town hall

As part of the 101 Reykjavik masterplan it was identified that Reykjavik needed a strong architectural identity in order to improve its status as the capital city of Iceland. The city is young and therefore does not have many architecturally significant buildings however the development of Yggdrasil aims to add to Reykjavikâ&#x20AC;&#x2122;s collection. It is the intention that the four significant buildings be joined through city trails and marketing strategy within the masterplan to increase the cities identity to the rest of the world.

Yggdrasil aims to have a strong regional impact by connecting its research and tree species to outreach programs and buildings around the region and country.

Creating efficiencies in a system

The relationship between the research building, growth building and arboretum through the process of growing a tree. Firstly research is gathered in the labs and tested in small LED growth labs. Then once a species is showing promise the saplings are grown in scale using Blue and red light for photosynthesis under a nutrient rich Hoagland solution.

Once the saplings reach 1-2 foot, which takes 2-3 months, they are transferred of the research building and into either the growth building or arboretum.

Only a small selection of trees will be planted in the growth house as this allows researchers to monitor the trees and for those species to act as a library to exhibit to the public.

The trees in the arboretum will be sequentially moved to allow land fallow and moved to outreach facilities across Iceland for planting once large enough.

ENTRANCE FORECOURT Improving way-finding Arboretum

The volume of both public and private visitors the arboretum and research centre means that the entrance forecourt is key for wayfinding around the site. As part of the Reykjavik masterplan sustainable transport is due to be implemented across the city resulting in the majority of people arriving by foot or bicycle. The land which would have been used for hard landscape to accommodate vehicles has instead been given over to create landscape pivot points which reduces the need for signs and the clash of public and private users of the buildings.

The forecourt also provides facilities for sustainable travel such as cycle stores and good walking

A GATEWAY TO THE ARBORETUM Creating a structural entrance

As you arrive and journey through the entrance forecourt you are immediately drawn to the trees inside the growing building. This draws you closer to the where the building expresses its structure through the oversailing roof from the research building acting as a canopy to both entrances and a moment of tension where the buildings almost kiss.

The landscape of the forecourt continues beyond the large CLT column structures acting as guardians to the arboretum which once you pass through are revealed trees of the arboretum as the two buildings disappear into the landscape.

A BEACON IN THE PARK A centre of activity in winter

Reykjavik’s long dark winters mean that socialising in winter is difficult for Icelandic people particularly in public space. As part of the Reykjavik masterplan it was planned that the park would act as centre of winter socialising using lighting installations and geothermal heating to create areas for events forming ‘the city of light’.

Yggdrasil aims to tie into this strategy by using LED lighting to grow trees and during the winter months using this light to illuminate the growth building acting as a beacon in the city. Yggdrasil and the arboretum aim to become a centre for winter activity in Reykjavik.

WINTER IN THE PARK Functioning in winter

As you walk through the snow filled air, brushing against snow covered trees, the promise of a warm drink from the cafĂŠ is so close as you peer around the last turn of the path and greeted by the glow of the growth building. The lush green leaves contrast against the now white arboretum as you walk closer towards building. Every step you take is closer to a refuge from the cold and a sip from a warm mug amongst the green trees.

Mirrored proportions

CONTINUITY TO STREET Creating architecture of place

Creating continuity in architecture is important for a how a building sits in its context. This is particularly important for a city like Reykjavik which has a strong architectural typology present. Yggdrasil has mirrored the typology which creates a strong relationship to place.

The buildings public nature meant that it was important that the typology was contested in order to make a landmark building in the city. Yggdrasil will use new materials and its roofscape will form architectural surprise in the interior of the buildings.

RESEARCH ELEVATION Scale 1:250

The façade of the building is a regular repetition of angled charred Siberian larch broken by deep set window reveals and two ends of full height windows which express the warm qualities on materiality within the building. The regularity of windows is a result of the labs on ground and second floor however the first floor has a different treatment.

As a result of the Reykjavik’s contrasting lighting conditions it was important to allow as much light in during winter and create levels of shading in the summer. As a result there is a continuous row of the façade which uses blackened timber slats- at the same angle as the rest of the face- to cover large window openings which sit on the third floor. This floor will have the most amount of people and therefore the impromptu meeting (a common way of sharing knowledge) was and important factor in the design. By creating long continuous, regular light along the circulation space and void allows for flexible meeting spaces and consistent lighting qualities within the building.

CHARRED LARCH FACADE Reducing material waste

Material sourcing and preventing waste is key in Yggdrasilâ&#x20AC;&#x2122;s construction therefore it is the intention that all of the timber be used to create various patterns on the facade and furniture in the building The external cladding will be charred Siberian larch at 125mmx50mm section. All timber is to be class 2/3 according to BS EN 350-2. Charring the timber creates resins and extracts in the wood create a high resistance to decay and rot, the high density of Siberian Larch means that it is more difficult for decaying organisms to penetrate the wood creating a natural lifespan in excess of 50 years.

Four different patterns will be used on specified areas of the building which will use any waste timber from the other parts of construction.

THE SECOND FLOOR A dancing roof

From the second floor mezzanine the researchers are able to appreciate the undulating pitched roof dance off into the distance. The large atrium provides good air circulation to the building and the varying roof pitches give a high quality acoustic adding to the success of the space. Large glass openings allow each room on the second floor to be easily identifiable and generous circulation creates more space to accommodate for impromptu meetings and the sharing of knowledge.

Services strategy

PRIVATE LABS Service vents run in suspended ceiling to main ventilation routes in corridors.

Flexible services

The private labs face out on to tree tops so researchers and contain rich qualities of materials found around the building. The flexibility of the labs is integral to the design and therefore uses suspended ceilings and floors to run services such as water and power allowing for easy access for future changes. Pre routed channels in the cassette walls will house the hot water system (power by geothermal heat) with the intention that the labs will gain ambient heating.

Ambient heat from hot water pipes.

Geothermal power and hot water Water and drainage delivered below and above to allow for flexible labs space.

All furniture will be crafted locally with all fixtures and fittings maintaining a matt black finish to allow for a researcher to easily locate a connection.

The LED growth labs will have a connected ventilation system to the rest of building allow for greater efficiencies in heat recovery and the circulation of fresh, warm air. Reykjavikâ&#x20AC;&#x2122;s outside air temperature will very rarely be of ambient temperature for internal conditions therefore warm air is recovered in the atrium spaces of the building. This air will be rich in moisture/ C02 because of human activity and therefore ideal for the plant growth. The air collected and combined with input of other airs as Nitrogen and Oxygen controlled by the researchers, which once suitable is pumped into the labs to enhance growing the rates of saplings. The air that is given off from the plants, which is warmed by the LED lighting is then collected and mixed with fresh external air via a heat transfer which is then delivered to the building and ground creating a flow of warm clean air around the building.

GROWTH BUILDING The jewel of the arboretum

The Growth building is the arboretumâ&#x20AC;&#x2122;s jewel in the landscape. The building houses 13 growing bays which monitor and exhibit new and existing species of tree for the public to enjoy and interact with.

The nature of species which will be grown do not require high levels of heat such as a typical tropical greenhouse and therefore the has been designed with passive solutions to create efficient conditions for the researchers whilst also maintaining good levels of internal comfort for the public to enjoy the building.

The building maintains a structural regularity of CLT timber columns set at 4 metre centres and fixed with expressed matt black moment resisting joints to the ground and roof beams. It is the intention that the structure is obvious therefore the largest possible size panels of glass have been used to minimise the amount of mullions and transoms visible. Using a structural utilized glass system which fixes back to the structure allows for moment joints to protect the faรงade from wind loads. The true beauty of the building are the trees which grow within it therefore the architecture is subtle with the only expression being the obvious connections between materials being finished matt black making them stand about against the green back-drop. A large stainless steel mesh runs at high level hung on the buildings service routes which dance along the joint between wall and roof. This provides environmental benefits explained later in this report whilst not effecting the views in and out of the building.

Lateral services Services zones located at building edges to provide flexibility centrally.

EXPERIENCING THE BUILDING How visitors experience the growing bays

Heated walkways

Geothermal heated air delivered through ground air vents to increase user comfort.

Flexibility is key for the functionality of the building and its success for the research and monitoring of trees. This has resulted in lateral services routes which create a fully flexible central space allowing for the flexible growth of tree in the bays. The lateral service routes also provide key benefits to the way visitors can experience the building in a comfortable environment.

These zones, explained in the three diagrams on the left, are heavily serviced with power and heating from a geothermal system creating comfortable circulation routes around the building which will not affect the growing conditions of the trees which are specific to a researchers needs.

Circulation routes Two main circulation routes are connected around each growing bay.

REYKJAVIK ARBORETUM Iceland’s new national centre of trees New road layout

Yggdrasil arboretum, Iceland’s new national centre of trees is located in Reykjavik’s Hljómskálagarðurinn park is the heart of Eufrogens and the Icelandic governments efforts to reforest the country. This 26 acre arboretum accommodates all the tree species used in the re-forestation of Iceland through its various outreach facilities across the country. The arboretum offers various trail routes and activities for all ages and abilities, a perfect day out for all the family. Yggdrasil aims to be as inclusive for visitors and tourists alike with a range of events running throughout the year which celebrate our mission to reforest Iceland.

Be sure to be on the look out for all the new species of trees, plants and animals that have thrived in the area following its opening in 2021.

The following pages will explain all the design decisions which have been made resulting in Yggdrasil arboretum’s success.

EXPLORING THE ARBORETUM

itie en Am

The masterplan of the arboretum follows the same geometry used in the placement of the two buildings giving subtle coherency to the site. Around the site there are small versions of growth houses and research centres which house educational facilities and amenities such as toilets and baby change.

Around these small buildings will be education and activity spaces which can be used by Yggdrasil to explain and educate Reykjavik on planting trees.

It is the aim that this will have secondary benefits on Icelandic peoples attitude towards trees aiming to result in residents taking their own initiatives in planting trees around the city and country.

The immediate landscape of the building proposal uses hard landscaping to frame planting beds which can be used by the researchers. The landscape aims to be subtle and focus attention on the growth house therefore a series of low level planting beds which will reduce the risk of overshadow to the building. Key material choices have been made to create a pallet which complements the connection of the buildings to the ground.

More detail of the landscaping around the building can be seen in the diagram on the adjacent page.

163

EVENTS A full year of activities

The arboretum will host a series of events throughout the year which will put Yggdrasil at the centre of Reykjavikâ&#x20AC;&#x2122;s social calendar. Yggdrasil will give the city not only high quality research but also an internationally recognised venue with the capacity to host festivals, concerts and yearly activities. Because of long winters the park becomes particularly active in the dark months expressing the LED technology and becoming a beacon in the city.

An example of the events which could be in Yggdrasil arboretum are shown in the 2019 calendar on the left with the recent forest festival which hosted numerous worldwide artists on the right.

IMPACT OF THE LANDSCAPE Tree growth through the years

The true quality of the arboretum will be seen in years to come when the species derived from project Yggdrasil have had time to grow to their full height.

In order for the project to have an immediate impact to the city of Reykjavik, semi mature planting, grown in the outreach centres across Iceland will be used in planting the immediate vicinity of the building. The park already has a significant number of trees which will be used as the basis for location of trail routes and education zones. There is a planting strategy over the next 30 years which aims to utilize the space made as part of the Reykjavik masterplan explained on the adjacent page.

IMPACT OF THE PROJECT Changing peoples perceptions

Planting trees in Iceland was historical something for the few eccentrics. However thanks to research conducted by project Yggdrasil this is a thing of the past. Various educational events will be run throughout the year sharing this knowledge onto the public to have secondary impacts on re-forestry in Iceland.

Yggdrasil aims to be seed which changes the Icelandic landscape.

TRANSPORTATION Removing trees from the growth building An opening section of the facade

Accessibility is key for the removal of trees in the growth house and access for maintenance. At key parts of the building, shown in the diagram on the adjacent page, the structural bracing will be moved to 8 metres above Ground floor level. This will allow roller doors to be installed which can be used for larger vehicles to access the trees. The circulation routes of the building will be co-ordinated the building management to allow for small vehicle access at various times out of visitor hours.

For larger species of plants, the front end of the faรงade can be opened up which will allow for large vehicle access, however these will only be implemented in times of closure of the building.

STRUCTURAL STRATEGY A structurally proud building Structural strategy model

Project Yggdrasilâ&#x20AC;&#x2122;s architecture is formed through its structural capabilities which has led to a continuous dancing roof becoming an iconic feature of the project. A well-crafted CLT timber frame is set on a 4 metre grid which is connected by expressive steel joints anodized midnight black to create a relationship with the charred Siberian larch cladding on the research building.

The two buildings aim to have identical forms to further strengthen their appearance in the landscape, therefore structural integration was necessary in order to create a strategy which could work for both a timber building and a glass building.

The following pages explain the decisions made which has made this possible.

PRE-FABRICATION A sustainable construction process

Icelandâ&#x20AC;&#x2122;s cold winters mean that construction is primarily limited during the summer months therefore Yggrdasil will use pre-fabrication in order to reduce on-site construction times. The established forestry outreach centres across Iceland will act as pre-fabricators during the winter months enabling the CLT cassette walls to be made. This will then allow quick erection of the building during the summer months.

Pre-fabrication of the building will reduce the amount of waste created with all the saw dust being used to compress into wood fibre insulation panels. Any timber which is then not needed for construction will be turned into long burning wood pellets for the biomass heater which will add to the energy input of the building.

Final Fix

The building quick erection means that it will be weather-proof far quicker than conventional construction therefore internal and final fixes can be made far sooner in the process

5

Completion and handover

Pre-fabrication of the building allows for the completion to be far sooner.

It also demands a higher quality finish to the building as the panels will be checked prior to leaving the fabricators.

RESEARCH BUILDING Cores and frame

4m centres

The research buildings structural strategy- as explained in the diagram on the left- is CLT timber frame set at 4 metre centres which is then stablished with three concrete cores along the building. The central zone of the building, acting as circulation for people and services, will be made up of structural timber cassettes which will act as loadings for the floors. There will be movement in the building, particular with the expansion of timber over time, therefore movement joints are placed every 20 metres.

All structural timber is to be strength graded and stamped and confirmed on site. Minimum free end bearing of timber sections is to be 90mm Any gaps between joist ends to be filled with masonry or timber noggins. All new timber is to be kept dry on site prior to use and stored so as to prevent warping along minor axis.

GROWTH BUILDING Stiffness/Torsion

Tied frame and glass

Unlike the Research building the growth building must rely on bracing and ties to stabilise the frame.

Every other frame will contain ancon steel ties whilst there will be a continuous line of steel SHS between timbers. Like the Mont Cenis academy by Jourda & Perraudin Architects, the building will use structural utilized glass supported by the mullions and transoms. The glass faรงade will produce high levels of wind loading which is addressed through the transoms fixing back onto the frame using movement gaskets.

The scale of the frame means that connections between materials and the ground have been designed which allow moment and therefore reduce the stress on the structure, the joints are explained on the next page.

Wind load

187

CONNECTING THE FRAME Structural connections of the timbers

The structural connections between the timbers are expressed through a steel flitch plate which has been designed to resist moments an therefore reduce the stress on the structure through wind and snow loads. Reykjavik experiences slight seismic activity from Icelandâ&#x20AC;&#x2122;s volcanoes and therefore when designing the timber frame this was taken into account. Each timber has been sized based on AIA CLT timber sizing and will withstand loadings 2.5x their weight allowing for resistance to movement and the capacity to take the load of the glass roof and snow loads.

191

CONSTRUCTION SEQUENCE Work stages and construction

Due to Icelandâ&#x20AC;&#x2122;s young planning history there is no work stage plans for construction, therefore the RIBA work stages will be referred. It is expected that stage 4 will continue over the dark months with construction (stage 5) to commence the following spring 2020. Stage 6, handover is expected before the following winter with the building opening for research in November 2020 and the arboretum spring 2021.

Stage 5

A-Site preparations

B-First Frame

The site firstly needs to cleared and then the foundations, basement and ground floor slab can be poured. Due to the nature of the site, the public park will remain open and the site protected with heras fencing

The concrete cores will be cast in situ providing stability to the CLT frame. The frame will be erected under covered conditions to reduce its exposure to UV, rain and cold weather. The slab of the growth building will be checked for appropriate fixings to be integrated.

ENERGY STRATEGY A fully sustainable building

Project Yggdrasil aims to tie into Reykjavikâ&#x20AC;&#x2122;s energy masterplan by utilizing the sustainable options available. There is also the ambition that the project and arboretum can produce energy and water enabling the buildings to be closed system which can function off the main grid. There are key targets which Yggdrasil aims to meet set out below: -Production of 1million saplings a year under LED controlled conditions.

-100% Geothermal heating system with electricity production using biomass in the winter months -Solar power use during summer months.

-An exemplary example of timber construction in Iceland -Controlled Laboratory conditions using passive options.

-To achieve BREAM excellence, particularly in construction standards and energy performance.

-To become carbon neutral through the afforestation of trees in the arboretum.

A building that reacts in winter

Reykjavik seasons are dramatically different and therefore the environmental strategy has to accommodate a range of climatic possibilities.

During winter the city experiences cold temperatures and heavy snowfall which results in the summer environment strategy varying slightly. The changing strategies are explained through the diagrams on this page.

FLEXIBLE SERVICES Future proofing the building

Already outlined in the report the project has a series of micro-strategy which add to the overall environmental aspirations of the building. The overall strategy is explained below: The primary services strategy of the building as been designed to centralise service routes which will enable flexibility should the building need to change function in the future. All services will rise up through the cores where they can be circulated around the building easily. In order to increase travel distances and efficiencies, the SVP and greywater runs are located closer to the cores where the toilets and showering facilities are stacked. Yggdrasil aims to have has little impact on the environment as possible, therefore all the grey water will be collected from the roofs and stored in water tanks.

Pre-fabrication of the timber cassette floors and walls mean that services runs can be-determined prior to construction reducing the time needed for tradesmen to be on site. However, to further improve the flexibility of the spaces, suspended ceilings and floors will run in all labs to allow for lab benches to be able to moved in the future.

Both buildings will be connected to the same plant to reduce the need of enclosed rooms in the growth building improving its purity in the landscape. They will be connected via a sub-plant under the courtyard which has access via either the basement of the research building or the courtyard itself. Each building must achieve the following ventilation outputs:

Centralised serive runs

1) Mechanical extract to w.c @ 15ltrs p/s 2) Mechanical extract to Labs @ 30ltrs p/s 3) Mechanical extract to Utility @ 30ltrs p/s 4) Mechanical extract to Growth @ 40ltrs p/s

regulations

PART B: FIRE AND SAFETY Approved document B compliance

B1- Means of warning and escape

B5- Fire Access

Due to the separate natures of the buildings there are two separate classifications of fire risk.

The research building is under category 5 and the growth house category 6 therefore both horizontal travel distances to a protected stairwell is 18m in one direction and 45m in two. The linear nature of the buildings has resulted in the installation of fire curtains and fire protected corridors every 12m in both buildings. Both buildings will be fitted with heat and smoke detectors with an integrated system of audio and visual alarms too BS5839-9. Escape routes and doors exceed the minimum requirement of 1100mm wide.

According to document B5 of the building regulations and buildings below 2000-8000sqm with a highest story being no more than 11m above ground floor level must have a minimum of 15% perimeter for access. Due to the nature of the building there is hard landscape around both buildings to allow the movement of tree species around the arboretum. The research building ( A higher fire risk) has direct adjacencies to a main road in Reykjavik for sufficient access for fire vehicles.

The three service cores also contain a fire riser for access to the upper floors.

B2 & B3- Internal fire spread The primary construction material is CLT therefore fire spread is high risk. To reduce the risk a sprinkler will be installed throughout the building and all primary timber structure will be fire protected to 120minutes as per building regulations B2 Appendix A table A2. A fire retardant paint to be used on timber to BS 5839-1:2017. The Research building has three protected cores which enables safe exit and provision for ambulant recovery.

ESCAPE STAIRS B1- Means of warning and escape

For structural purposes the Research building contains three concrete cores which house the escape stairs and means of access to the upper floors. The cores create three areas of escape and refuge in-case of a fire and are fire-rated up to 120minutes. It is expected the occupancy of the building will exceed 60 people but be no more than 600 therefore a required minimum of two exits is necessary.

FIRE CURTAINS B1- Means of warning and escape

Due to the open nature of the growth house compartmentalisation is vital for the fire strategy. fire curtains offer greater flexibility to designers, enabling larger open plan areas as part of a fire engineered solution. However, since they often replace other fire safety measures, they play a vital life safety role and must be maintained to high standards to ensure they will perform as expected in the event of a fire.

Recommendations include a capability for multistage deployment, inclusion of emergency retract controls and obstruction warning devices. The standard also recommends that deployment speeds should range between 0.06m/s and 0.15m/s.

PART M: ACCESS Approved document M compliance

Project Yggdrassil has been designed to allow everyone, no matter what ability the means to access and use all areas of the building and arboretum. In areas of the building which provide level changes, provision has been made to create a non-biased, inclusive design.

Access & Approach As part of Reykjavik’s wider sustainable travel plan Yggdrasil will be located within walking distance multiple tram stops. The site will be located on the Inner city line with a new dedicated tram station being built during construction of the buildings.

At the base of the arboretum is the national gateway hub which has connections to Keflavik airport adding to Yggdrasil’s draw as an international recognised institute. Yggdrasil will offer facilities for staff to use bicycles by having staff changing and showering.

The masterplan allows for sustainable vehicle methods to be used for delivers to buildings within the city therefore Yggdrasil utilises the sites location to the Hagrimka street which will act as the delivery and service artery for the building. The growth house café will use front door delivery.

Entrances, Circulation and Navigation All doors provide level access into each room , with main entrance door widths exceeding the minimum requirement of 1200mm. To allow the building to be accessible across all levels a series of lifts have been incorporated into the design in prominent positions, generally located to provide the structural core of each main vertical circulation stair. This enables clear navigation and removes design discrimination by positioning lifts in separate positions to the main route of travel. All lifts have a minimum 1500mm x1500mm clear zone in front of the lift doors and all stairs

have level landings with no more than 12 risers without providing a level landing which is equal to the width of the stair. All stairs throughout the building have consistent risers (170mm) and goings of (300mm) withhandrails provided to both sides.

Within the growth house access to the mezzanine level is provided through platform lifts integrated next to the stairs.

Sanitary provision Accessible WC’s are positioned on each floor level and are provided with outward opening doors of sufficient width for wheelchair access and incorporate a minimum 300mm nib to the pull side of the door to allow ease of access for wheelchair users. Separate male and female toilets, changing and showering facilities are provided for research staff on the ground floor. Separate male and female toilet facilities for visitors are provided around the park with the numbers calculated using expected maximum occupancy numbers and recommendations set out in BS8300.

Security Project Yggdrasil will experience high volumes of visitors and staff particularly during events.

It is therefore important that access is managed through secure points in the building. The growth building is a free building and therefore access as been controlled to either through the main entrance or café. The research building will be controlled through a series of fob access doors with off the main entrance foyer with a controlled reception guarding the stair.

CDM Construction design management (2015)

Pre-construction

Construction

Maintenence and use

Under the CDM regulations a principle designer must be appointed, this does not necessarily have to be the project architect and the role could be carried out by another design team member or external consultant. Although in this case it will be assumed the project architect will take on this responsibility as they form an integral part in the design team, with clear oversight on all aspects of design and coordination. The principle designers role in the pre-construction phase is to carry out the following:

The site occupies a prominent city location, however its position is not particularly constrained by compact urban development, with neighbouring buildings in set back positions allowing sufficient access and space around the site. Main arterial roads which pass close to the site along its South-West and North-West boundaries provide efficient and safe means for construction goods to be delivered to site. However, due to the site proximity to potentially high numbers of pedestrians using the park a secure site boundary will be erected using hoardings and will be managed to protect and separate construction works from members of the public. Site access will also be carefully managed and separated from pedestrianised walkways with timed allocations put in place for deliveries which avoid peak city rush hour periods. Project Yggrdasil will maintain a high standard of construction practice during the whole process, including:

Yggdrasil is working building with a high volume of public and private people therefore key site strategy will be implement by builing management to co-ordinate deliveries and tree removal to avoid the risks resulting from overlap.

- Plan, manage, monitor and coordinate health and safety in the pre- construction phase between all parties and design team members.

- Advice and provide assistance to the client to bring together pre- construction information and also provide relevant information to designers and contractors in order for them to effectively carry out their duties.

- Work with design team members and other designers to eliminate foreseeable health and safety risks to anyone affected by the works and where it is not possible reduce or control associated risks.

- Ensure everyone working on the pre-construction phase is properly and effectively communicating and coordinating work.

- Liaise with the principle contractor, keeping them updated on any risks that need to be controlled during the construction phase.

A pre-construction risk assessment will also be carried out to identify potential risks to surrounding buildings and city occupants. This may include but may not be limited to a noise and air quality impact assessments in order for risks to be removed at the design stage or mitigated during construction.

- During construction all workers must complete relevant health and safety training prior to working on site and must wear the correct personal protective equipment (PPE) at all time.

- The primary structure primarily pre fabricated , with large elements being manufactured off-site. This not only provides quality assurances in material finishes but reduces time required for construction on site and the associated risk attached.

- For the construction of the outer facade which mainly consists of glass or timber clad, risk assessments will be needed to identify risks and for measures to be put in place for construction workers to safely work at height and for the safe delivery of materials to height.Around these areas sufficient protection will be put in place such as fixed scaffolding with permanent access stairs. Safety nets will also be installed.

220

All necessary considerations were taken into account during the design stage to allow safe maintenanc of the building fabric whilst in use: - In order to allow windows of the growth house to be cleaned and maintained they have been specified as self cleaning with extra provision made available in the doors designed to a sufficient width to safely allow a MEWP boom (cherry picker) to enter the hall to provide a safe working platform for maintenance workers to clean and maintain the windows.

In order for this to be successful the slab has been designed to withstand such loads - All external timber cladding is demountable to allow the ongoing maintenance of moving parts and for necessary future repairs replacement.

process & reflection

Exploring the site section (Plan 3) Section A_A

DEVELOPMENT OF PLAN Planning iterations Public cafe addresses the park

The nature of the site meant that there many contextual parameters which made forming an initial concept the most difficult task in the process. therefore I chose to focus on the functionality of the building and the way people would experience it in both public and private aspects.

Public amenities block Shared courtyard

Pub-

Gateway Private to the park

Identity to street

A key precedent was cloister architecture and the way this created privacy which could be particularly relevant for the protection of tree species. The initial idea was to sink the central courtyard and give visitors a ‘look but don’t touch’ view of the trees however, this created un-certainty with the way the building would present itself to the park.

Prevailing winds

Growing house entrance Research entrance Largest amount of sunlight hours per year Entrance forecourt Site entrance

From then the building continued on a journey which tried to address how the building could stay both public and private and how the building could present itself to the park. This process is explained on the adjacent page.

How the environment effects the building.

224

Plan 1

Plan 2

The plan restricted the level of control over privacy and created issues with lighting and circulation my sinking the courtyard.

The decision was made to introduce a solely public aspect to the west wing of the building which allowed visitor access.

However the building lacked any realtionship with the park and instead closed itself off.

Plan 3

Plan 4

With the buildings struggling to form a relationship to the park I decided to separate them which created greater control of public and private users. The architecture started to form more of a realtionship to the park acting as a gateway.

The growth building was given more priority on the site and therefore enlarged whilst the ends of the building were experimented in order to create a more prominent entrance.

MAKING A BUILDING Designing through models

Throughout the process models have been used as a key method in the design. This enabled me to gain a key understanding in space and volume and help develop a key understand of materiality and detail which would be reflected if the building was to be built. The models worked particularly well in rapid testing of ideas and the development of the structural capabilities of the roof.

The collection of models on the next pages where integral in the conception, design and delivery of Project Yggdrasilâ&#x20AC;&#x2122;s design.

DRAWING A BUILDING Designing through sketch

In unison with models, sketching and diagramming was a method to quickly text ideas which then could be explored volumetrically through model. The following pages show a key selection of sketches which were used in the process and that had a particular prominence in the iteration of the design and the eventual delivery of project Yggdrasil.

During this process I feel that my ability to quickly communicate through sketch has improved, particularly during consultant tutorials which added to the coherency of the design.

REVIEWS Feedback and contemplation

Review 2- Sketch scheme

Review 1- Concept

Prior to this review particular interrogation was spent on the resolution of the building plan and the way the scheme, as a whole, became more specific to site. The development of the arboretum gained the critics enthusiasm, however the way the two buildings represented themselves lacked coherency, particularly with the intention of the building acting as gateway to the park.

The intentions of the building were well received, however I feel that I developed the architecture to quickly which led to criticism on the sunken courtyard and the way the building related to site. There were concerns about public and private access and whether this type of building was necessary in the city without having a fundamental public use.

234

Review 3- Detail

Review 4- Final presentation

Project Yggdrasil began to come to life during the detail and tectonic stage of the project. The structural exploration became the key focus of the building which enabled a positive conversation with the critics on how this could be pushed even further. Constructive advice was given on the capabilities of timber frame construction which was used in the development of the final design of the project.

The final design was well received by the panel of critics and I gained positive comments on the coherency of the design concept and its delivery into a valuable piece of architecture to the city.

It was expressed that I try to further develop the environmental aspects of the building and how project would react in the harshest of Reykjavikâ&#x20AC;&#x2122;s winters. It was nice to see the project come together and the use of models enabled a higher level of engagement from the critics.

235

236

Personal Reflection would take on a public site , I feel that the level of detail reached during the design process created a building which is ingrained in the context of Reykjavik and is a strong addition to the city.

The final project of my architectural education has been the most rewarding academic project I have undertaken to date. Working with my peers on the masterplan of Reykjavik identified all the challenges in architecture which comes with designing in a context far different to the UK. The masterplan enabled a level of understanding of place which was ever present through the design process, creating a richness of architecture which has its place in Reykjavik.

If there was further time to explore and develop the design I feel I would focus on developing the link between the arboretum and building more , with a greater focus on how people would use the park and the buildings as a collective potentially with the exploration of smaller installations and furniture around the park.

During the design process Project Yggdrasil became real in my mind. This helped me to interrogate the details of the building down to the way people touch, see and experience the spaces and the way the â&#x20AC;&#x2DC;Project Yggdrasil brandâ&#x20AC;&#x2122; could represent itself to the world.

Although this presented challenges along the way, particularly with the form the building

Although Project Yggdrasil will never be built, the lessons I have learnt in its conception, design and delivery will stay with me throughout my future career as a more socially-minded, confident architect.
