Being a key community building on the quayside many functions will require after dark operation. In illuminating this key façade on the quayside, in a manner consistent with the other main facades, a sense of direction and orientation is achieved at night. It is proposed that the external lighting is broken down into 4 components:
Typical architectural features to Market Hall facade
In this instance, it is suggested that the most effective form of façade lighting is by way utilizing the high level adjustable downlights. This ensures that luminaires are mounted for ease of access and maintenance without being exposed to damage and vandalism or being a potential source of glare.
The shadowing created by any protruding horizontals and verticals will lend itself to the overall night time appearance of the building.
By concentrating the downlight on to the vertical columns, much of this downlight reached the floor without any obstructions. The window ledges and frames between the column positions will capture and control light spillage to create a visually pleasing effect.
Concealed lighting illuminates the architectural features of the building without creating glare or obstructions
Intent: As the building wraps around into Market Hill the Market Hall and its neighbour (The British legion) should announce to the pedestrian that they are entering the Quayside. A dynamic lighting impact should be created for these highly ornate architectural building. Similarly, pedestrian movement along the harbour font is assisted by making these two building facade focal points on the streetscape.
Ambience: Low level street lighting, (lux), which allows dynamic light pattern to be fully appreciated. Light pattern and light colour temperature will be key elements within the impression.
Generic Product: To avoid a flat visual appearance and to achieve strong modelling it is desirable that the greater proportion of light comes from a single direction. A dramatic effect can be achieved by directing luminaires at a glancing angle to produce shadows and highlights. This is to be achieved by close offset mounted directional downlights mounted at high level. This method will prove to be the most practical in siting and installation.
The high level parapet which projects from the façade is to be lit from behind which create a silhouette of the vertical plinths and helps to illuminate the sloping roof behind. The silhouette effect of the plinths against the illuminated roof will give prominence to the architectural detail.
The vertical columns to the building façade provide an architectural feature which is to be down lit. The gabled entrances and architectural features are to be illuminated by discreetly mounted spotlights, these are to be used to downlight. This will highlight the entrance and provide spill light at ground level to assist with safe entrance and exit at night.
The intended light colour temperature for the of the building façade is the be 'cool' to accentuate the grey block rendering to the façade. In contrast the red brick entrances are to be illuminated with a 'warm' colour temperature. This will aid direction and provide decorative form and function to the facades.
From a distance the dominant vertical lighting and roof illumination of the buildings will appear consistent, however, closer up significant features of each building will become recognisable. The differing methods of façade lighting (uplighting to the Legion and downlighting to the Market) will help to differentiate each buildings use and purpose but still maintain visual consistency of light pattern. Additional downiight to the vertical columns of the building facades increases visual definition of the building illuminated as a whole. Again the close mounted spotlights provide illumination to each specific vertical feature. This helps to define the architectural characteristics.
It is intended that the lighting scheme is extended past the limitations of the façade lighting to these two buildings and a holistic approach adopted which includes the adjacent seating areas and open spaces. This lighting theme adopted within these areas will be consistent to that of the remaining quayside and will also be linked to that of the Market Hall and Legion. The lighting design for this area is to be part of additional documentation for the holistic approach of the quayside.
Lighting options to seating area at rear of Market Hall
'Cool' white light pattern behind the parapet wall at roof level with concealed luminaires will provide decorative light spill to the lower tier slope.
'Cool' white spotlights at high level to wash the main façade and accentuate vertical column details.
'Warm' white spotlight to entrance portico, illuminating the doorway and gable detail.
The variances in colour temperature enhance the render finish and hue within each area and provides a lit contrast for definition of access routes.

Restrictions on locating luminaires to this elevation, regarding paving, vandalism and glare necessitate the mounting of luminaires to the façade at high level. This lends itself to the architectural features and uses for this elevation. Mounting luminaires at close offset at high level provides a wash down the front of the elevation and illuminates the ground level paving to the façade. The wash light pattern will accentuate the rendering texture of the façade and will define architectural features and protrusions. The intent is to create a narrow beam light distribution to each of the vertical columns that dominate the four facades.

Discreet mounting of fibre optic lens points allows for a weather proof, vandal resistant low temperature solution. Internal mounting of the light source ensures that once the fibres are installed into the fountain they are a fit and forget item. Consequently, the only maintenance required will be for replacement of the single lamp source.
Fountain feature to Market Hall
These positions to the bowl and fountain frontage. Flammable, its features are a great option for use in the water. Flammable provides decorative illumination to the water, depth, and surface.
Similar to option 1, this solution excludes the submersed lens point, which is the same as the other option, when viewed from above. It will appear that more light is reflected from the view.
