Urban Strategy

The synopsis for the Urban Strategy is to create a new FUTURE PROOF IDENTITY FOR MILLBAY, that is based on a synergy between multiple site users: port authority (ABP), renewable MARINE TECHNOLOGY industry, EDUCATION SECTOR, tourism & leisure and private residential development.

Plymouth is currently on the short list for the second wave of investment made available for cities and regions by the government. If the city is successful with the ‘CITY DEAL’ there will be INVESTMENT into projects all over Plymouth with the majority funding a new centre for marine technology on ex mod owned ‘South Dockyard’ Devonport.

Millbay is the area where the marine technology industry in Plymouth can grow from, it will be a catalyst not only for change but for a new path into the future for the identity for the area. This pioneering industry will put Plymouth and the South West of England on the map as a base for all future renewable marine technologies. It is where KNOWLEDGE is PRODUCED, tried and tested to then be implemented anywhere in the world.

Key Issues

Site Permeability:

The site is currently isolated and has little/no routes traversing the space.Our aim is to creat a major route through the site running west to east. This route will be the main area of focus and the key facilities/ spaces will be situated along it.There will also be a secondary route running north to south through the site.

Landmarks:

In order to locate ones self in Millbay there are a number of key buildings to remain/ develop as landmarks. This will not only help with navigation around the space but also be the first thing tourists will be attracted to when arriving on the ferry and cruise ship.

Industry Sparks Employment:

Once the main research facility is created, a variety of supportive industries would set-up around it to develop/ manufacture the prototypes for testing. These facilities would be able to draw on the large number of unemployed people in the area (as opposed to bringing in a workforce from somewhere else).

Key Views:

There are a number of key views across the site that are seen as important and therefore these would dictate certain spaces of the masterplan. These views are from a number of key locations (that will be busy) and view key landmarks.

Historical Rail Connection:

Millbay was once a thriving industrial port that was well connected with the rest of the city because of a comprehensive rail network. This network has since been removed, but re-establising city wide connections (spatially and/or non-spatially)is important to the success of the development.

Master Plan

14

Associated British Ports:

A small proportion of local people will be employed to run and manage AB Ports operations with the ferries and cruise ships.

Industry:

The Marine Technology Industry will be the main source of local employment in the immediate area. It will also create a new identity for Millbay and be a trial for this type of industry before it is implemented in Devonport at South Yard.

Site usage in master plan

15

Tourism & Leisure:

Engaging activities is at the heart of the scheme. Working in symbiosis with the marine Industry this complex of white water rapids and green spaces will encourage local peo-ple and tourists to have active and healthy life-styles; health and well-be-ing.

Residential:

This area of the site will be sold for high density apartments & maisonettes. The majority shall be of a very good quality with 30% social housing to encourage a mixed community.

The site:My project is situated in the Millbay area of Plymouth and is located on the main pier to the south of King-point Marina. This site is challenging as the building will be exposed to the marine environment on three of its elevations.

Building: The building is set in the centre of the master plan to encompass all aspects of the strategy. It is a multi-use building that caters for many different users as well as exhibiting and demonstrating the renewable marine technologies manufactured on-site through the EDUCATION SCHEME. This will be in the form of APPRENTICESHIP PROGRAMMES & SELF INTEREST WORKSHOPS. It has been designed with young people with a disinterest in main stream education in mind. Skilled employees make visits to local schools twice each term, the idea being that a short 30 minute presentation and workshop is given. In-school presentations are given to every year group from year seven up to year thirteen. Lower years will receive simple ‘interest’ lectures whilst later years will have the opportunity to attend a course day each week at the Marine Technology Centre. This is a progressive scheme working up to 3 days per week attendance with the EQUIVALENT TO AN NVQ BEING AWARDED at the culmination of the course.

Need:The project will address the ISSUE OF LOCAL UNEMPLOYMENT. By having the NEW INDUSTRY in the heart of Millbay it not only creates a new identity for the area but also produces jobs. Millbay in the past has had shipbuilding at its core that provided employment in its locality. The project is going to benefit Millbay and the City of Plymouth not just through economic growth but also social and cultural through engagement with local people and TOURISM to inform the SPREAD OF KNOWLEDGE and promote health and well-being. The physical TECHNOLOGY PRODUCED will be distributed internationally to be DEPLOYED in areas that it is needed.

Facilities: Uses will include a fully functional workshop for carrying out many different activities and processes of manufacture. The main relationships are between the young ’self interest’ workshops and the industrial processes that are taking place in the building. Other uses will include a marine heritage museum and gallery, cafe, water sports hub whereby the wake board cable and sailing area can be managed from, there will also be a landscaped area where spectators can view white water rafting and kayak events. Part of the building will be dedicated to a low energy residential program to be directly tested and implemented on-site.

Funding: There are several different stakeholders active on-site, ABP, developers, City council. I see the funding for the project coming mainly from these parties. However there should be some contributed by government, Sport England and potentially the Heritage Lottery Fund.

Rock labyrinth

This close to ground maze of concrete blocks, set out in rows to slow air movement down is known as a ‘rock labyrinth’. It draws air in from outside (hopefully not assisted by electric fans) and either pre-cools or pre-warms it depending on what time of year it is. Summer or winter.

A

Solar gains

The entire length of the building is subject to intense southerly solar gains throughout the day. Measures have been considered to mediate this through facade treatment; areas of brisoley have been strategically placed where over solar gain will occur.

B

Natural cross and stack ventilation

There is no mechanical ventilation system to circulate air. Three of the four immediate facades are surrounded by water, so air flow and air pressure on all sides of the building at any times of day or night should be constantly changing. Therefore successfully venting the building through the facades

C

Electrically controlled ventilation with manual override

There are many roof lights in the main roof which can be electronically controlled to mediate internal conditions

D

Green roof system

The 500mm+ thick roof structure offers the benefits of thermal, mass storage and regulates internal temperatures, whilst the generous overhang on the south facade also mediates the amount of solar rays entering the building. Water that falls onto this roof is vital for the sustenance of the vegetation at the same time as retaining it to reduce flash flooding in the local area

E & E1

Spine wall

Formed concrete at a thickness of 1000mm running the entire length of the building, acts as a thermal storage heater whilst keeping key spaces apart from one another to assist temperature regulation between areas an easier task

Heating strategy

CHP

I have opted for a Combined Heat and Power plant to heat and power my building. The main advantage to installing this system is that the slow constant heat output is perfect for maintaining the water temperature in the swimming / training pool.

Heat loss calculations

Fabric heat loss:

Pf - Rate of fabric heat loss = heat energy lost over time (W)

U - U-Value of element considered (W/m2 K)

A - Area of that element (M2)

t - Difference between temperatures assumed for inside and out (degrees celsius)

Inside temp assumed - 17c

Outside temp assumed - 5c

Pf = U t

Ventilation heat loss:

Pf = CvN V t 3600 seconds per hour

Volumetric heat capacity is 1300 J/mK

1300 X 1.5 X 4,341 X 12 3600 = 28, 216.5

Total rate of heat loss = Fabric heat loss + Ventilation heat loss

27,230 + 28,216.5 = 55,446w

Reflection

Looking back over this journey highlights to myself, the amount of thought that has gone into detailing a large building such a this one. The Marine Technology Centre for Learning. I have come to realise that it is a difficult task to make a project that successfully translates the core values set out in the urban strategy. The building I have designed up until now has tried to incorporate these strategic layers and translate them through physical form. The placement on site, orientation, levels and components of the design are just simply the containment (the physical stuff) from which activity is created, nurtured and lead to evolve. People are the key factor within this designed system. It is reliant on the diverse user groups that make the building function. The project and its ongoing workshops and activities I hope, would spark interest within young disinterested people as well as everybody else to go out, play, learn and create.
