LONGSHAW SEED BANK AREA RESEARCH THE PEAK DISTRICT
More than a third of the national park (35%) is designated as Sites of Special Scientific Interest (SSSI) where important plants, wildlife and geological formations should be conserved. Most are privatelyowned though often publicly-accessible.
Resident population: 38,000
It has 65 miles of off-road dedicated cycling and walking trails and we own 34 miles of disused railways:
Visitors: The Peak District National Park has 13.25 million visitors every year (STEAM, 2018) and is one of the most popular national parks in the UK. It is NOT the second-most visited national park in the world after Mount Fuji – this is an error which has been widely-repeated on the internet, but is not true.
An estimated 20 million people live within one hour’s journey of the Peak District. More than 50 million people live within four hours’ journey.
Nearly 90 per cent of the national park is farmland (around 1,800 farms).
Around 520 sq km (202 sq miles) is open access land – open to walkers without having to stick to paths
Climate: average rainfall 1025mm a year (Eng/Wales av. 985mm), sunshine 3.9 hours a day (Eng/Wales av. 4.3), average temperature 10.3ºC (Eng/Wales 10.3ºC).
It has 1,600 miles of public rights of way (footpaths, bridleways and tracks) including 64 miles accessible to disabled people.
Landscape: impressive gritstone edges (the Dark Peak); steep limestone dales (White Peak); 196 sq miles (51,000 ha) of moorland; rolling hills and farmland (south west Peak). Caverns famed for rare Blue John stone, 5,440 miles (8756 km) of dry stone wall, 55 reservoirs supplying 450million litres of water a day.
SITE ANALYSIS
LONGSHAW SEED BANK CHOOSING A SITE
SITE TWO: This site is on the exit from wooded area on the edge of an open space spanning across Longshaw estate where cows and sheep graze. This site is on a slight incline and can look across the valley at amazing views. It also has pedestrian access from the back of the site which is on the higher level, which could be am interesting feature that drives the buildings scheme. This site had high levels of wind however this could easily be resolved in design.

Although most views are block there is the opportunity to frame perspectives. There is grazing cattle on site which could either be embraced or resolved in the scheme.
This site is very close the main carpark at Longshaw and is the closest to the visitors centre and café out of the three sites. In addition it has road access running alongside the site meaning it could be useful for deliveries in the building. And finally there is a natural stream running g through the site which could be a beautiful feature in the building’s design or be used as a source of energy/ sustainable tool in the scheme.

LONGSHAW SEED BANK SITE CONDITIONS & FEATURES
SITE GRADIENT & CONTOURS: The site has multiple level changes, the gradient of the site is approximately 20.8º. With a 3.8m change in level.
Shale and gritstone are much more impermeable which is why the Dark Peak soil holds much more water forming the very acidic peat bogs. Because it is so acidic, only specialised plants grow here. Prone to frost pockets.

However, its high carbon content means it acts as a ‘carbon sink’ i.e. a store of carbon that would otherwise be released into the atmosphere and add to global warming. It also acts as a sponge for rain water, thus slowing down the run-off of rain water and helping the prevention of flooding in surrounding towns and cities .

The soil at Longshaw estate is very wet and boggy, this is because of the characteristics of each layer: • Limestone dissolves in rain water, cracks are enlarged and so surface water soon disappears underground. • Gritstone absorbs water very slowly and so has rivers and bogs on it's surface. • Shale is physically weak, but, if undisturbed, it forms a barrier to water. However despite the soil’s ability to store water, the flood-risk from surface water remains very low.

LONGSHAW SEED BANK MASSING OPTIONS PLACEMENT SURVEY:
VIEW SURVEY: This diagram highlights the views in different directions from the site. The brief asks us to consider these views in the design and layout of our building. The education space for example needs good views, where as the vaults don’t need any views.
This area is in the north and set into the gradient (cold lack of sunlight) – good for the vault rooms as they need to be dark and temperature controlled (cool).
This space has the best views over towards white peak across the valley, these spaces require good views.
This area gets the most sun throughout the day so therefore is perfect for growing.
This space gets some good views, is central in the site so has good access to all other spaces.
This diagram shows which areas on the site are most appropriate for elements of the brief. Exhibition / Education

Some spaces are getting very little light. There's a lack of ventilation space through the building, needs a more open-play layout No consideration of accurate space sizes and hierarchy.
• •
This design considers the existing desire lines on the site instead of creating new. It considers solar strategy when locating the storage facilities in the north (coolest area of the building). Similarly the indoor growing space is located in the most ideal location for the most sunlight.
• • • • • •
The growing space could act a great location for ventilation strategies. Cooler service spaces, vaults located in the north, this is sensible because they don’t need light either. Good lightning in the education space & exhibition space. Indoor growing space is located in the centre of the building, this could mean there’s a lack of light getting to this space. The outdoor growing spaces will be shaded early morning/late afternoon. Some northern spaces are cramped together causing ventilation issues.

There is a lack of light getting to the exhibition space, it has north light however it may need artificial lighting in order to maintain lux. Indoor growing space gets full sun however it could block light and view access to other spaces.

This design considers the gradient more than the other options, it uses the gradient into two steps which will mean less need to level the site out. This design has a better use of diffused north light and the idea to block more direct sunlight with the indoor growing space.

•
•
The spaces that have been places in the internal growing space may block some light to the rooms stacked towards the east of the building. The stairwell and lift could be places further towards the north as they’re located where a room could make better use of the conditions.
FINAL EVALUATION Overall this is the most appropriate design it considers daylighting, passive solar gain and uses the internal growing space to help light the building as well as be helpful for stack ventilation later on in the design process. It uses the gradient to into advantage places spaces that need less light and lower temperatures closer to the hill/under ground.
• • •
The spaces are very bulky and floors need have spaces broken up between them Moving between buildings could be problematic in bad weather conditions and whist trying the transport seeds, equipment etc. The buildings could cast shadows over each other which would make some areas in the north very shaded and dark, this would mean excessive artificial lighting would be needed which would use a lot more energy.
•
PROS
• •
This design had split the site int three parts, two located in the south and one larger one in the north, this is helpful for allowing light into the north side of the building between the gaps in the west, south and east, this improving daylight conditions Spaces that need less light or need to be cooler have been placed in the north. The vaults have been placed underground where temperature can be better controlled.

This design takes into consideration the obstacle that the gradient proposes, it stacks most of the spaces up against it and sunk into it, The internal growing space allows light to be diffused to the rooms stacked against the gradient. This design is both visually interesting and uses the site boundaries in a clever immersive way. By having the vaults in the ground temperature control made much easier and it eliminated passive solar gain. Rooms that need access to views have sensible been places on higher floors. Spaces that need less light or need to be cooler have been placed in the north.

EVALUATION - IDEA 1
• •
This design is really interesting and the placement of the growing space in the south is very sensible since this would get the most direct sunlight, however this would also run the risk of the space becoming very hot, so good ventilation and temperature control would be needed. Cooler spaces and circulation spaces such as the stairs and lift have been sensibly located in the north.
Similarly to the previous option moving between buildings could be problematic in bad weather conditions and whist trying the transport seeds, equipment etc. Again the buildings could cast shadows over each other which would make some areas in the north very shaded and dark, this would mean excessive artificial lighting. The shape shape of the building in the west would completely block light from the building in the east.
FINAL EVALUATION
FINAL EVALUATION
This design has an interesting concept with splitting the building up however I ultimately this this could cause more issues because of shadows cast from the buildings, bad weather conditions and transporting things between the buildings. It would also mean having multiple lifts therefore using more energy which is unnecessary.
This building is problem the worst option out of the three since there is little consideration of solar analysis and allowing light into all spaces, its also doesn’t uses the gradient to its advantage like the other designs. Overall this building would probably been quite dark but also could get easily overheated due to passive solar gain.

The indoor crowing space aids ventilation and circulation and is immersive in the buildings desire.
This diagram shows the noise levels in each of the spaces. I have grouped together spaces that may have higher levels of noises and separated them from spaces that are going to be much more quite, using the atrium (internal growing space) as an open space that diffuses the sound through the building making it feel much quieter.

After looking at occupancy I determined which might have the highest energy consumption because they're being used the most. I also looked at spaces that will need artificial lighting, energy to control temperature and energy to power equipment. Spaces such as the vault will need a larger amount of energy to keep them cool and for lighting. The labs will need energy to power equipment.

The spaces that have been places in the internal growing space may block some light to the rooms stacked towards the east of the building. The stairwell and lift could be places further towards the north as they’re located where a room could make better use of the conditions. 50 FINAL EVALUATION
Overall this is the most appropriate design it considers daylighting, passive solar gain and uses the internal growing space to help light the building as well as be helpful for stack ventilation later on in the design process. It uses the gradient to into advantage places spaces that need less light and lower temperatures closer to the hill/under ground.
The labs have been positioned to allow for maximum daylight and sunlight levels, they require a high LUX level of around 750 for precision work. The education spaces have access to north and west light to reduce glare and whilst maintaining access to views. In addition, all rooms that require a lux of 150 and comfortable temperature levels are grouped together. This reduces the surface to area ratio of the insulated envelope, saving materials. Cooler spaces such as the vaults that need temperatures of -18 have been placed underground, eliminating passive solar gain and daylight helping with seed preservation.
-18
All rooms that require comfortable temperature levels all year round are grouped together towards the top of the building. This reduces the surface to area ratio of the insulated envelope, saving materials. In addition cooler spaces such as the vaults that need temperatures of -18 have been placed underground, eliminating any passive solar gain, by placing them underground temperature control will be much easier to manage.

FINAL MASSING IN PLAN:
FINAL MASSING IN SECTION: The indoor growing space runs down the west side of the being from north to south, this allows for the south light to be diffused through the building, blocking direct sunlight and helping to avoid passive solar gain, it also aids daylight in the north on duller days.
Having the outdoor growing space on the roof gives full sun all day long, perfect for growing, no shading from the building
SEED PREPORATION SPACE

By having these rooms against the gradient I am protecting the building from noise from the adjacent road and as well as protecting it from passive solar gain in the east making the temperatures easier to control in the east and during the morning.

OUTDOOR GROWING SPACE
EDUCATION SPACE
CIRCULATION
Having the indoor growing space in the south west of the building also exposes to prevailing winds, this will hep ventilate this space as well as the rest of the building through stack ventilation. I can create vents at ground level that allow the cool prevailing winds into the building and up along the gradient, with the hot air escaping through skylights WEST and ceiling vents.
Stacking rooms at the back of the room not only allows you to gain access from behind the building it also gives the building enough height to gain access to views over the valley, this is specifically helpful for the education space and exhibition space where the brief asks for good views.
SEED VAULT
By suspending these spaces within the internal growing space it will help with cooling, allowing a flow of air around the spaces which will help with ventilation. As well as this is helps utilises otherwise wasted space and gives better vantage points for views and good lighting.
By stacking rooms that don’t need good daylight and heating against and within the gradient I can control the heat and light getting to these spaces. This is particularly helping in the seed vaults where the temperature and light need s to be controlled in order to help preserve the seeds.
In my design I want the internal growing space to surround some rooms, this will allow light to pass through the entire building and provide more light in the north. In the north I have place rooms that will not be occupied for a large amount of the time and rooms that don’t need as much sunlight. In addition the north is much cooler therefore I have places the colder storage vaults here as the temperature will be easier to control with out passive solar gain.
The best views from the building will be towards the north and west therefore I have placed room such as the exhibition space and education space facing these directions. So they get diffused light and have access to the views.
The south west f the building is relatively unprotected from prevailing winds, this can be harnessed as a method for cooling, the flow of air and wind can be taken in through the internal growing space and can be used to aid stack ventilation within the building. The wind will allow cool air into the space and then this can escape through the skylights.
By using the roof for the exterior growing space I do t have to consider shading from the building or uses space of the site that I need for internal spaces. The roof area will get full sun throughout the day which is ideal, making it the most sensible location 9

The widest part of my building (and the site) is in the south, this means a large area of the building will receive large amounts of direct sunlight, which will result is large amounts of passive solar gain. For this side of the building I will need to look at methods of solar shading, to avoid overheating and too much direct sunlight whilst protecting access to views.
To the east of the site is a main road that can be noisy at times mean the west of the building will need protection from noise pollution. I have set the building into the landscape this allows it to be shielded from road noise as well as a method of heat and light control.

WINTER SOLSTICE– BUTTERFLY SHADOW DIAGRAM
During winter the sun is very low and I have a lot of glazing around the south and west of the building, this will result in passive solar gain which could help heat the building, however the sunlight will need to be diffused to make the space more comfortable, reducing glare and direct light.
SUMMER SOLSTICE – BUTTERFLY SHADOW DIAGRAM The west side of the building is fully glazed meaning low winder sun will directly impact the space and make it extremely bright with direct sunlight and could result in large amounts of passive solar gain.
There are also shadows affecting the east of the building, however because of the slope and the way I have organised the spaces in the building, there is little need for light in these spaces or they can access it from the west. Because of the gradient of the site and high summer sun there area very small shadows through the summer months. This is partly due to the way I have designed the building into the slope.
The gradient of the removes any chance of getting sun from the east.
Trees in the west/ south west help to block prevailing winds and some direct sunlight. However, there may still be the need to add louvers to this side of the building.
A roof overhand will be needed in the west, east and south to help sheltering outdoor space and providing solar shading for internal space
DATE: 21ST OF DECEMBER TIMES: 8;00 AM – 6:00 PM
I have added automatic louvers to this glazing, these are solar powered so they can measure when the space is getting too much light; tis means I can ensure the space is a comfortable temperature at all times, all year round and the lighting is appropriate for the plants and users of the space.
The high sun and lack of overshadowing means the roof garden will get direct sunlight all day long, this is perfect for the needs of plants however could make the roof dry out, therefore a good irrigation system will be needed.
DATE: 21ST OF JUNE
TIMES: 8;00 AM – 6:00 PM
The shadows that can be seen mainly affect the north of the site, on this side of the site I will need to consider some kind of artificial light. I will have to have smaller windows on this died to reduce heat loss so getting light into this side of the building may be difficult, especially during summer.

ROOF SOLAR LEVELS: WINTER
The west of the building in completely glazed, however because of the buildings overhang and the adjacent trees the internal spaces have been shaded by the direct winter sun. These internal spaces will be made out of translucent materials in order to maintain light levels.
ELEVATION SOLAR LEVELS: SOUTH - WINTER
ELEVATION SOLAR LEVELS: NORTH / WEST - SUMMER
In summer the internal spaces light levels doesn’t really change however the north of the building is getting much more light, during winter there will be lost of heat loss in the north so I have reduced the glazing here as the glazing's only purpose is to access views not to let in more light.
ELEVATION SOLAR LEVELS: SOUTH - SUMMER
ROOF SOLAR LEVELS: SUMMER The south of the building will undoubtable be getting the most direct sunlight especially in winter, this is evident in this graphic, the high levels of light will cause passive solar gain especially in the glazed portion of the space. I will need to implement louvers and an overhang to counteract this light.
ELEVATION SOLAR LEVELS: SOUTH / EAST - WINTER
The east of the building is completely shaded, built against the slope of the site. The gradient shades this side of the building especially in winter when the sun is low in the sky. This creates cool spaces in this portion of the building, these rooms wont get any light so I need to consider this fact in my design.
Very similarly to during the winter the high levels of light will cause passive solar gain especially in the glazed portion of the space. However less light is getting to the internal spaces therefore I would need changeable louvers so they can be removed in summer or be automated by solar panels.
ELEVATION SOLAR LEVELS: SOUTH / EAST - SUMMER
Although the east of the building is completely shaded, built against the slope of the site. The gradient shades this side of the building however due to the high angle of the sun during summer some light can get into these spaces, however the slop might be built up more again this side of the building.

AUTOMATIC WINDOWS - VENTILATION
STACK VENTILATION USING THE INDOOR GROWING SPACE AS AN AREA FOR AIR CURCULATION AND VENTILATION THROUGH WINDOWS, HOT AIR ESCAPES THROUGH AUTOMATIC VENTS IN THE SKYLIGHTS. THESE VENTS ARE TEMPEARTURE CONTROLLED AND CO2 CONTROLLED MEANING THE SPACE IS ALWAYS A COMFORTABLE TEMPERATURE AND HAS GOOD OXYGEN LEVELS MEANS THE SPACE IS EXTREMELY COMFORTABLE AND USABLE.
NOISE ABSORBING BALUSTRADES ON OPEN CIRCULATION SPACE
Automatic windows/vents controlled by heat and CO2 sensors
With having an open plan space, there needs to be a consideration for noise, especially in. the teaching spaces. To do this I have added noise cancelling balustrades to reflect sound into space and absorbing sound escaping from them. This will create a more zoned environment and avoid the quiet spaces being made unusable from the more public spaces.

WINTER SUN THE WEST SIDE OF THE BUILDING IS SFULLY GLAZED MEANING LOW WINDER SUN WILL DIRECTLY IMPACT THE SPACE AND MAKE IT EXTREMELY BRIGHT WITH DIRECT SUNLIGHT AND COULD RESULT IN LARGE AMOUNTS OF PASSIVE SOLAR GAIN. I HAVE ACDED AUTOMATIC LOUVERS TO THIS GLAZING, THESE ARE SOLAR PWERED SO THEY CAN MEASURE WHEN THJE SPACE IS GETTING TOO MUCH LIGHT; TIS MEANS I CAN ENSURE THE SPACE IS A COMFORTABLE TEMPERATURE AT ALL TIMES, ALL YEAR ROUND AND THE LIGHTING IS APPROPRIATE FOR THE PLANTS AND USERS OF THE SPACE. The skylights create large circular spaces of light in the building which is a great visual feature whilst adding to daylight levels throughout the building. These skylights are an important part in keeping the plants growing in the internal growing space alive as well as lighting the seed spaces.

Most heating and cooling is by radiant effect from the concrete floors/walls/ceilings which have pipework embedded in them, cold water from the rain water harvesting system runs through these. This will help keep the vaults cool, aiding temperature control
