Dublin Port Development


Client: Dublin Port Company
Value: €4m

The development of a new public space adjacent to the Dublin Port Centre building on East Wall Road. The “Opening up of the Port Centre Precinct” project aims to reflect the Port’s “Soft Values” policy which, amongst other things, sets out to remove physical barriers between the Port and the city of Dublin and identify opportunities to open up physical and visual access to the Port and spaces within it. IN2 provided Mechanical, Electrical and Environmental services for specialist lighting design for the exterior areas, public realm areas and special features such as the Crane, wind turbines and entrance turnstiles.

The redeveloped precinct achieved the following objectives:
• Relocate and reconfigure car-parking facilities to the south of the Port Centre.
• Remove the barrier presented by the existing stone boundary wall to the Port Centre.
• Realign and soften boundaries to the south and east.
• Integrate with the surrounding City and enhance the local
environs / environment
• Facilitate public engagement with its new sense of public place
• Enhance the building’s visible gravitas and add significant value as a headquarter building of significance.

Specialist Lighting Design
IN2 developed a lighting design for the scheme taking into account the principal considerations as outlined below:
• Provision of adequate illumination to contribute towards the safe use of the site by both vehicles and pedestrians
• Provision of a visually interesting environment
• Enhancement of security
• Containment of the lighting within the site to levels which will not impinge adversely on surroundings
The proposed lighting design and analysis included the following:
• Upward directional floodlighting for the Dublin Port Crane Feature
• Ground recessed upward directional lighting for smaller site features, such as wind turbines and entrance turnstiles.
• Brick lighting for internal access paths
• Bollard Lighting for pedestrian routes
• Column lighting to the car park

IN2 assessed the predicted performance and associated impact of the proposed External Lighting scheme using state-of-the-art lighting simulation software, Relux – an interface package called Radiance. This is a software suite of highly sophisticated lighting simulation tools for both visualisation and prediction. The analysis utilised quality life-like rendered images and an accurate calculation process associated with the proposed lighting scheme in terms of light produced (lumens), directional intensity (candelas), reflectance of materials, etc.

Challenges and Achievements
The complete external lighting installation had to be designed in accordance with the regulations for electrical services as ETCI National Rules for Electrical Installations ET 101 2008 as well as Design Criteria from CIBSE and CIE regarding Illumination levels and “Obtrusive Light” to neighbouring buildings respectively.
Guidelines stipulate:
• Design Illumination level of 20 Lux, measured horizontally at Ground level.
• Maximum “Obtrusive Light” Illumination level of 5 Lux to neighbouring buildings, measured vertically on a Wall.
The design criterion for Obtrusive Light outlined above varies by category of Surrounding Light Environment; namely, Natural, Rural, Suburban or Urban. Urban has been selected for this Dublin Port project which corresponds to a CIE designated E4 area meaning that it is an urban centre area with high night-time activity.
The design criterion for Permissible Sky Glow is given in terms of Upward Light Output Ratio (ULOR). For E4 areas, the maximum ULOR as a percentage is 25%.

The predicted performance of the external lighting installations was assessed in detail, in-house. IN2 provided analysis of the predicted illumination results for both the overall site (ground) and the neighbouring areas (adjacent roads) in order to assess design illumination at associated potential light overspill respectively. The results demonstrated that the design proposal, whilst providing a design Illumination level of 20 Lux to car parking areas, had negligible impact on the surrounding environment and that the light overspill to neighbouring areas does not exceed 5 Lux, in compliance with design criterion for obtrusive light.
