    City of Cardiff shows a vision for lighting that goes way beyond illumination

    6th April 2018
    Chris Jones
    Lead Electrical Officer, City of Cardiff Council

    The City of Cardiff Council has embarked on the installation of more than 14,000 Philips connected LED street lights. The aim? To help support safety, security and tourism in the city whilst helping reduce its carbon footprint through significant energy savings and increased operational efficiencies.


    The innovative project covered all major traffic routes into the city and was achieved in just nine months. It followed a public consultation where Cardiff residents outlined their needs from city street lighting which resulted in the use of a warm white light that can be controlled remotely to ensure the right light level on each road or district.  A change in street lighting can be subtle, but the right light can offer many benefits to a city and can contribute to keeping citizens safe at night.


    So what tangible benefits will the people of Cardiff notice?


    The top priority is to ensure maximum benefit for residents and capitalise on potential cost and energy savings. Philips Lighting has given Cardiff an infrastructure that will grow with its needs and provide quality light to make its citizens feel safer. With continual monitoring, the Council can now respond instantly – such as increasing light levels at peak times outside schools and stadia and in the city centre.


    In the future the City of Cardiff plans to deploy sensors that monitor weather patterns, temperature or noise levels. This will allow city engineers to make more informed decisions, such as when and where gritters need to be deployed. Presence detection sensors will enable council leaders to understand better how many people are accessing or using certain areas or facilities in the city whilst allowing the lighting to respond to any such detection. Sensors and camera systems offer vital information to enable cities plan and keep areas safe, as well proving better facilities for the ever-evolving city’s needs.


    The council’s target is to reduce its street lighting electricity charges by about 60%, that’s a saving of more than three-quarters of a million pounds every year. Whilst energy saving is one advantage, another one is using lighting as a catalyst in enabling Cardiff’s desire to become a truly smart city. Today, Cardiff already uses the relational database management system (SAP HANA) for financial purposes in the city. However, the capability exists to easily enable this into an open data platform that can join various systems used within the city such as transportation, traffic systems, pollution monitoring, parking monitoring and lighting.
