Mitie reuses luminaires at The Mound
Mitie has reused the pendant structures at Lloyds Banking Group’s building The Mound in Edinburgh rather than replace them.
The company had the current T5 fluorescent, dichroic and cold cathode sources upgraded by local firm Stoane Lighting to LED with wireless mesh controls added, reducing energy by 78 per cent. Light levels met relevant wellness targets and Lloyds Banking Group’s own specification as well as that in Society of Light and Lighting guidance.
The corresponding carbon avoidance by refurbishing and reusing the pendants and was calculated at 28,000 kilograms of equivalent carbon dioxide (or 49 per cent) using the CIBSE TM65.2 method when compared to installing new replacement luminaries.
The savings have supported Lloyds Banking Group in its ambition to halve energy usage, achieve ‘Net Zero Operations by 2030’ and improve the overall working environment. The unique building is now showcased in the best possible light.
The Mound is an iconic building which sits in an area of historical importance that connects the Old Town and the New Town. The building, designed by architect Sir William Chambers, is a Category A listed structure. The renovation project aimed to upgrade the internal lighting and lighting control systems to improve the working environment for colleagues and reduce energy consumption, while preserving the building’s historical significance.
The Group challenged Mitie to design a new lighting and control scheme fit for a modern working environment while reducing energy and waste. The building was previously refurbished in 2008 and the scheme included the installation of unique and highly decorative pendant lighting.
‘Due to the historical design of the building, we worked with a specialist lighting designer to review the existing lighting scheme and deliver a design which aligned with all aspects of the brief’ said Mitie. ‘To save embodied carbon, we decided to refurbish and reuse the pendant structure. We engaged with the original lighting manufacturer, based locally in Edinburgh, to rework the pendants to support new modern LED lighting and control on site.’
This included the integration of a wireless mesh lighting control system to provide presence, daylighting and scene control to each pendant lighting control.
