Case study: LEDS C4 creates a connected lighting scheme in LOOM

LOOM Barcelona is a flexible work space solution, based in the prestigious Torre Glòries, and located in the technological and creative district of Barcelona. The project covers a total of 2,500 square meteres, over three floors, and required project-specific lighting to differentiate the spaces. The LEDS C4 Smart Light for Office control, connectivity and digital services solutions has been applied to optimise maintenance, energy saving and efficient management of all the spaces.

LOOM is about creating a workspace focused on people, optimising their performance and boosting their creativity. LED C4 was required to carry out the lighting project with this in mind, in addition to the supervision and monitoring of the work from start to finish.The project had a range of requirements, with the primary focus being able to adjust the artificial lighting depending on natural light conditions, and so avoid major contrasts with the 360-degree natural light entering the building in order to avoid fatigue and headaches, and reduce energy consumption.

It was necessary for the project to comply with the Workplace Standard EN12464 on lighting comfort and glare for the worker. In addition, the client needed to be able to control the activation of the lighting of the common areas or meeting rooms depending on occupancy, while being able to control and analyse the degree of occupancy of rental rooms to respond to customer demands.

In response to all of the requirements of the project, the LEDS C4 lighting project and consultancy unit designed a lighting staging focused on the building’s architecture and its people, using connected lighting systems that generate differentiated spaces, offering a high degree of comfort and design.

At the product level, a combination of linear and cylindrical architectural lighting was used, with decorative lighting options that add character and adapt to the needs of each space. Lighting products were differentiated according to the space and function, from formal directional lighting in meeting rooms, to more diffuse lighting in less formal settings.

Given the architecture of the Torre Glòries building, consisting of a double-glazed structure that ensures natural light all day, a sophisticated system was installed to control the use of sunlight and to adjust usage depending on occupancy, based on 150 Wireless D4i smart sensors, distributed over three floors and perfectly integrated into the lighting. As a result, the lighting is completely autonomous and is self-regulating depending on natural light and occupancy, with up to 85 per cent energy saving. In turn, the lighting can be customised with remote controls located in every room, with four default setups and fine-tuning buttons for every two work stations. Thanks to this flexibility, adaptation to each user is guaranteed and it brings a high added value to the installation, ensuring maximum productivity.

Connected lighting with LEDS C4 Smart Light for Office enables the project to be managed remotely, making it possible to monitor the installation, change the regulation profiles and visualise the lighting data through the DALI D4i platform. The installation’s key data points are the energy saving due to natural light and occupancy, the temperature of the spaces, as well as real-time reports of the state of the lighting and their flow maintenance, all through graphic panels and data records. The data is available locally and in the cloud, and can be used by third-party applications or APPs via API, or through a BMS system, to provide a number of functions such as customising the temperature and lighting of the rooms, or reserving the spaces online.
