Cycle-friendly BREEAM Outstanding offices at JJ Mack
The JJ Mack Building scored an unprecedented 96.42% in its BREEAM assessment, not only giving it a rating of Outstanding but making it the most sustainable building in the UK, with no other building achieving a higher score.
The JJ Mack’s embodied carbon and energy use put it within the top 1% of office buildings globally. It has an embodied carbon figure 15% lower than the current average LETI design target and 52% lower than the regulated Targeted Emissions Rate defined by Part L of the Building Regulations (2013).
Earth Friendly Concrete (50% embodied carbon saving over standard) and UK steel were used in its construction. 144 photovoltaic panels sit alongside 885sqm of biodiverse roof pre-planted with native wildflowers, grasses, herbaceous perennials, bulbs and sedums. Bug hotels, bird and bat roosting spaces, and two bee colonies support biodiversity. It is connected to the Citigen district network giving benefits in energy efficiency also nullifying roof plant so allowing an additional office storey within the St Paul’s view corridor.
The building marks the transition between the more intimate Smithfield Market and the busier grander Farringdon Road. The granite façade on Charterhouse Street responds to the smaller scale of the listed PLA building next door, and the dramatic south-facing double-height lobby is located here, funnelling pedestrians into a handsome central lift bank. Just past the main entrance, the massing rises to turn the corner on Farringdon Road towards the station and its new Elizabeth Line.
For cyclists, there are exceptional facilities (eg racks for bikes and lockers for folding bikes, washdown and maintenance areas) accessed directly from Farringdon Road. A suite of spa quality changing and drying rooms beneath lead directly into the main lobby.
