Iconic Grade II Listed Building, London

Modernising heritage with sustainable solutions

This historic and iconic grade II listed building system was at end of life & reaching the point where they would become beyond economical repair.

A grade II listed Victorian Iconic building, located in the heart of London, faced a critical challenge. Its heating system was nearing the end of its life cycle, teetering on the brink of becoming too expensive to repair. This landmark, steeped in history since its inception in 1896, posed a unique energy dilemma that required an innovative and heartfelt resolution.

Working hand in hand with a structure that had seen the evolution of time, and covered an expansive 34,931 square meters, required a solution that not only addressed the energy challenge but also respected the building’s storied past. The building is also home to a significant TV production company, various hospitality businesses, and a number of office spaces, which meant disruption needed to be kept to a minimum.

Protech Group’s team of experts embarked on a mission to preserve the legacy while embracing sustainability. A new package burner system was meticulously designed and specified. This solution boasted multifaceted benefits, including a significant reduction in carbon footprint and NOx levels, alongside unwavering operational reliability.
