Synopsis of Brief “The central endeavour of this project is to use the medium of film to investigate the implications of the modern condition. Cinema - the seventh art - has many affinities with architecture and engineering in that its very essence intertwines technological invention, with the aspirations of ontological narrative... The project also demands the development of an attitude towards modern and historical cinema, and the moving image, through the themes of Darkness, Machine, Screen and Space. “
Reaction To us, Spike Island feels like an understated area, given its history and the wealth of creativity that it harbours from internationally acclaimed artists and businesses. We did not want to overwhelm the island’s unique character, but promote it on an urban level and bring its energy into the public domain.

Caixa Forum Herzog & de Meuron The building is conceived as an ‘urban magnet’, attracting people from a wide area to explore the building as well as the cultural program on offer. Not only to its cultural program but the building itself. The public realm is drawn beneath the mass of the former power station and up into the heart of the Forum.
Adaptive Reuse Historically, Spike Island was the site of working quays, shipyards, warehouses and associated dockside industries. With the decline in heavy industry in Britain there was a plentiful supply of disused warehouses and factories in harbour areas. Groups of artists began to acquire these spaces as studios from the 1960s and brought their creative energy to the UK’s abandoned ports.
The trend in artistic regeneration was influenced by the development of SoHo, New York. Artists infiltrated and took over the area known in the 19th century as ‘Hell’s Hundred Acres’, attracted to the cheap rents and large, adaptable spaces they could use both to live and work.
Space, London, established in 1968, was one of the pioneering examples of independent artists’ cooperatives in the UK, occupying warehouses in the South Bank’s Old Docks. Landlords positively encouraged their tenancy. Deterioration of properties and the increasing notoriety of dockside areas were reduced, and gradually the variety of business and tenants increased, attracted to the culture the artists had created. This pattern of gentrification can be seen throughout both the United States and Europe.

Auditorium Atlantida Josep Llinas The complex bridges between the consolidated town of Vic and future expansion areas as a ‘melted part of the urban fabric’. The public realm is folded into the building with varying levels of exposure. Above, the roof slopes down from the auditorium fly tower, spreading and folding over the remaining program and creating multiple entrances.
Fold Our proposal takes the archetypal figure of the industrial shed in its simplest pitched roof form. As the pitch runs through the building it distorts; rising, falling, dividing and merging, fusing the multiple program requirements beneath its continuous canopy. Both roof and floor planes work in parallel to guide the user through the building. The ground level rises, folding through the site from the Floating Harbour up to Cumberland Road. It unifies the building’s internal activities and connects them with the external landscape and broader context.

Node The objects found on the site act as nodes, anchored deeply within the industrial heritage of Spike Island. They are vessels through which the history of the site has been enacted, taking on multiple identities. The introduction of three cinema auditoria establish the Film Institute’s position on the Island. The nodes are orientated with relation to existing site forces and geometries, embedding its program within its historical surroundings.

Internal view of cinema
“Nevertheless there are plenty of examples to show that film is capable of better things; not a great many first-rate works of art, complete, coherent, and highly finished - the art is still too young for that, it is still too much in the experimental stage - but there are enough films to show in individual scenes, individual inventions, in the efforts of individual actors, what might be, what still lies hidden and untapped. And there is, in art, nothing to prevent one’s clinging to the little that is good, instead of the great quantity that is bad.� Rudolf Arnheim Film as Art, 1932

Interior finish
Sketch of timber-slatted ticketing office
Throughout the central space and inside the cinema, internal surfaces take on a ribbed appearance. This is achieved with layers of thin hardwood battens made from timber thinnings. A relief is milled in to the battens, creating an abstract, near moiré effect. On closer inspection a selection of key figures from film history can be seen. Laid to a fabric backing, this finish has noise attenuating properties, making it suitable for large, open interior spaces. The timber is also carried through externally to window frames and points in the façade which denote key entrances and openings to the building. Timber louvers and window frames in the facade highlight entrances and openings, and allude to the internal atmosphere. Internally, the material is also incorporated as a tactile finish to key pieces of furniture such as the ticketing office and bar. Faces from left to right:

Strand Analysis
049
The exhibition strand breaks through the Guinness Shed and connects the building to the city by means of a projected image on the glazed end screen of the studio. The projecting studio defines an entrance on the waterfront, giving access to a public exhibition and café within the original shed. The old station platform becomes a terrace, with the original train line being retained as the building bridges over it. The bridging structure creates an area of ‘inhabited steps’, an informal area for both teaching and film screenings.

The end of each strand is highlighted with an individual box window. In the case of the exhibition strand the glazed end acts as a film screen, projecting a moving image toward the city. Large ‘landscape’ openings relate more to internal spaces which demand a strong connection to the streetscape such as the bar Other more regular rectangular windows are placed according to internal forces such as the spacing of tables in the restaurant.

The restaurant strand responds to the Old Gaol Steps which are both a destination within the Wapping Wharf development for commercial and residential activity and thoroughfare for locals from the suburbs of Bedminster and Southville, cutting through the site to reach the Floating Harbour. The ground floor bar is accessible directly from the internal central space, and flows out onto the street terrace. The entrance to this area is aligned with the end of Ropewalk, and St. Mary’s Church Redcliffe.

1. Foundations The majority of substantial structure has been allocated to the south of the site to minimize foundation loadings to the poor ground conditions to the north.
2. Nodes Three heavily braced auditoria act as as ‘strong boxes’, providing lateral stability to the surrounding strand structures.
5. Floor Planes Six in-situ composite concrete floor panels are installed to provide lateral stability
6. Tertiary Structure The strand structure has a stiff, cross-braced roof that enables transfer of shear between the external façade of the connecting structure and the auditoria.
Structural Strategy & Construction Process
3. Strands A light Steel frame is erected with the bridge attaining longitudinal and lateral stability from a large truss and rigid portal frames along the length.
4. Fold Structure The roof structure consists of deep pitched beams, that reflect the notion of the strands weaving their way through the nodes.
7. Folds The exterior warm, non-ventilated zinc skin is attached using a lightweight Metsec wall cladding system or alternatively laid straight on to steel decking.
8. Founds The found objects are renovated with a refurbishment of the Guinness shed’s exterior skin and the Old Gaol Stable’s roof.

Fire Strategy Outlined below is an initial working fire strategy. With the scheme’s complex plan ranging over several storeys, including three nodes (auditoria), three strands (various program) and a deep core, a very complex fire strategy would be required that could be developed through investigation from the initial set below.
Warning and escape t t t t t t t t
Heat and smoke alarms installed within all parts of the building. Traditional audible siren to warn of a fire, as well as visual alarm (in the form of warning lights) for the hard of hearing. Sealed fire lobby connected to all three cinemas. Appropriate emergency lighting installed in all cinemas. Doors to cores and cinemas to be fitted with automatic closing device in case of fire. Automatically opening skylights within core space to allow ventilation in case of smoke penetration. All exits and routes to be at least 900mm wide. Hand held fire extinguishers distributed throughout building.
Internal fire spread - linings t t t t t t
Heavy installation of sprinklers within film archive and core. Kitchen and Film Archive to have 60mins fire rating with automatically closing fire shutter on serving hatches. All internal timber finished treated to resist flame spread over surfaces. Fire-resistant glass used within core spaces. Old Gaol Stables retrofitted to meet housing standards. Additional hand-held extinguishers provided in higher risk areas: kitchen, film archive, plant, projection rooms.

As the service life energy consumption accounts for the vast majority of the total CO2 usage of a development (carbon footprint) the environmental design aims to create an extremely efficient integrated system that reduces overall usage.
Ventilate
The auditoria and recording studios are mechanically ventilated using a low velocity displacement system. Due to the requirement for acoustic isolation and comfort, passive ventilation was considered inappropriate for these key areas. Ventilation is provided in large ducting at low speeds to minimise frictional losses and noise. The stands are passively ventilated using three suitable methods that take into consideration location within site, depth of zones and usage. Single sided and cross ventilation is achieved within the peripheral zones such as exhibition and classroom spaces. Stack ventilation has been effectively achieved within the deepest core of the plan, through the use of two ventilation chimneys that have been incorporated within the form of the small and large auditoria. The largest of the stacks achieves a maximum differential height of 10m, and an adequate opening area of 225m2. This shall be the main driving force for natural ventilation, with fresh air being brought in via underfloor vents that connect to the outside via ducting. To increase the efficiency of the ventilation stack, a southfacing glazing strip has been incorporated in to the chimney detail, thus increasing the rate of ventilation through solar acceleration.

The initial starting point is to reduce basic energy consumption. This has been achieved through the building’s structural strategy and massing. Steel structures have the ability to use significantly less material than concrete structures and are therefore lighter with less extensive foundations. With most of the substantial structure to the south of the site, the quantity and size of piles has been minimized, reducing cost and material usage. Lighting requirements will be limited to specific times, with Passive infrared (PIR) being used to illuminate public areas when a film is in progress. The core space requires lower light levels to aid in the transition between foyer and a darkened cinema. To reduce demands on heating and cooling systems a high level of thermal insulation has been applied to all external walls and roofing surfaces.
Recover
To make maximum use of energy within the scheme, a large proportion of usable high quality heat is to be recovered (50% efficiency assumed from recovery systems). These high grade sources include plant (55,000 watts) and projectors (4,000 watts). A heat exchange ventilation systems shall also be used to recover any excess heat from the three auditoria, recording studios and kitchens. This will then produce a realistic recovery assumption of around 59,000 watts for high grade heat and around 70% recovery through the heat exchange ventilation.
Reuse
The reuse of existing material and structure played a large part within the scheme. Wherever possible existing structures and objects have been incorporated and reused, reducing the initial embodied construction energy of the proposal. Key material choices were made on the availability and realistic sourcing of recycled material.
The floating harbour shall be incorporated in to an open loop heat exchange system, to be used as a heat source in the winter and combined with a Turbocore compressor in the summer to aid cooling. Although the film institute has a constant cooling demand for projectors, plant and mediathĂŠques all year round, an alternative passive strategy of heat recovery ventilation is developed to cool in the winter. Turbocore compressors are a highly efficient system, being a third more efficient than any conventional method. This system enables an efficiency of 1 unit of electricity equating to 5-15 units of cooling. There are a number of constraints that need to be considered in the implementation of an open loop heat exchange system: - The inlet and outlet have to be a minimum of 20m apart. - There may only be 50C rise between inlet and outlet water temperatures. - A license with an associated yearly fee must be attained from the Council for the extraction of harbor water. - The temperature of the harbor fluctuates from a minimum of 70C in the winter to 200C in summer
Solar
A large bank of south facing solar thermal panels cover the large auditoria to the rear of the site. These solar panels can generate up to 330,000 watts (values obtained from SWTHA).
Rainwater Harvesting
The roof plane of the luxury cinema is to be used for rainwater harvesting. With an adequate surface area, roof falls and proximity to plant and service spaces, it provides a useful water source. The downpipe and filtration system has been incorporated into the form of the cinema block.
A Stirling engine that utilises the waste heat from the heat exchanger, plant and a large bank of solar thermal panels covering the auditoria drives the mechanical ventilation. A Stirling engine can convert any available heat source difference into kinetic energy. The theoretical efficiency of a Stirling engine is limited by the Carnot cycle (40%) and directly proportional to the temperature difference between the two sides of the cylinder. The pressure of the working fluid also contributes to the efficiency of a Stirling engine. By increasing pressure and hence the thermal mass of the working fluid it may transfer more energy for a given volume. As we are working with a low temperature difference (600C) but a high volume (400kW gain from solar and plant) it is possible to attain 40kW of mechanical power. This is a conservative calculation, as a 50% transmission loss has been assumed. This level of mechanical power will be ample to drive the low velocity ventilation in the auditoria and recording spaces. Thus resulting in all mechanical ventilation to be provided passively. The engine will also be linked up to a generator so that when the ventilation demand is at a low the engine may generate a modest amount of electricity.
Alternative Generation
The Floating Harbour is flushed regularly (to avoid stagnation) and is replenished by the river Frome. The flow rate of the Frome is given as 1.7m3/s at a station above Bristol. For these reasons it would not be possible to generate sufficient electricity to warrant installing a water turbine running from the harbour to the new cut. With insufficient depth a tidal flow turbine in the Avon would also prove ineffective. On-site generation is almost always a compromised solution. As all generated power is fed in to the same energy grid it would make more sense to invest in an off-site wind generation program in a more suitable location.

Conclusion Our building was not designed to impose a new identity on to Spike Island, but deeply respond to its existing condition and make public its unique creative wealth. Film was used as a platform to fulfill this urban and social agenda. We feel that our low key proposal works on a local as well as on an urban level. Its responsive nature is evident through its form and materiality, balancing historical and progressive forces, urban and sustainable, as it folds to establish its position within the site.
The idea of adaptive reuse could have been further investigated, developing an architecture more responsive and flexible to the future demands of the community and city that it serves.
Our working process over nine weeks has been measured and coherent as we grew to understand the intricacies of the locale and how the program could penetrate and heighten its complexion.
