1 Broadgate is a landmark mixed-use development that offers primarily flexible accommodation for office, retail, leisure and food and beverage businesses. The building is a diverse, world-class development right in the heart of one of London’s best-connected locations, next to Liverpool Street Station and an important hub on Crossrail. Lower levels will offer up to 150,000 square feet of retail space, with approximately 400,000 square feet of new office space arranged over the upper levels, each with access to private terrace space.

The project prioritises wellbeing and sustainability, with smart-enabled design to enhance the user experience providing optimal control and indoor conditions to tenants.

A series of measures have been adopted to reduce whole life cycle carbon emissions and deliver zero operational carbon.

Advanced energy modelling has been used from early design stages with the design team engaging with the site Facilities Managers and framework contractor, and later with pre-let tenants to optimise design and collaborate on pushing the boundaries of sustainability aspiration.

Whole Life Cycle Carbon Assessment has identified opportunities to reduce the building’s embodied carbon at Practical Completion to 750 kgCO2/m2 GIA from an estimated 950KgCO2/m2 at RIBA Stage 3. Circular economy principles are being adopted in design and procurement, facilitating deconstruction and re-use.

The project features varying glazed areas and façade shading, raised sills, high light transmittance and solar control to optimise daylight and solar gain. A mixed-mode ventilation with flexible façades enables enhanced fresh air rates with demand control sensors. Highly efficient heat pumps, energy storage and secondary heat recovery for re-use by retail have been used. Long-span steel beams and bolted connections enable functional adaptability and future deconstruction. An attention has been given to prioritise native, drought-tolerant vegetation and the use of rainwater for irrigation.

1 Boradgate is one of the first UK Design for Performance Pioneer Projects in collaboration with the Better Building Partnership that targets an estimated Base Building Energy rating of 4.5 to 5.0 Star, following an Independent Design Review.
