Case Studies

Hadyn Ellis Building


The Hadyn Ellis building is a striking five- storey postgraduate research facility at Cardiff University, used for studying cancer, neurosciences and mental health. Internally, the building is formed of two blocks with a central atrium and will include a café, seminar suite, support services and administrative facilities. Working rooms will be light, airy and comfort cooled. Cutting edge sustainability features include natural ventilation, passive shading, and energy efficient lighting and control systems.

Open Technology’s LiGO system controls the lighting throughout the building. From the architectural lighting in the Atrium to the teaching spaces and labs, LiGO is able to provide the most energy efficient lighting operation for each area.

LiGO also carries out the testing of all emergency lighting, performing a weekly functional test and a quarterly duration test with all the results emailed to the estates department for record purposes.

There are 8 LiGO’s on site configured to control some 600 lighting groups. LiGO’s ability to ‘connect to Trend’ makes the DALI lighting controllable from the campus- wide Doorway supervisor that looks after 900 Trend Controllers. LiGO’s flexibility also meant that commissioning could be carried out quickly as different areas could be completed at the same time as they were out of action for other trades. Using LiGO significantly reduces the amount of electrical circuit testing on the site, which further cuts costs.


“We now have quite a few LiGOs around campus and can utilise any type of DALI lighting manufacturer which is a bonus for competitiveness in today’s market. We are scene setting a number of our lecture theatres and cinema standard areas with LiGO now in place of older Crestron dimmers. We are also using LiGO to dim our LED lighting.”
