Our Sustainable Solution

As the Building Services consultant on this project, as well as the BREEAM Assessor, we ensured that sustainability was at the core of the building’s award winning design and that passive and active energy efficiency measures were incorporated throughout. We provided guidance on the selection of ‘green’ building materials for all external and internal elements.

Some of the building’s key environmental features include:

Connection to the site-wide district heating network which provides close to 100% of the development’s heating and hot water demand.

Centralised hot water storage to maximise the benefits of the hot water heating provided via the site- wide low carbon CHP network, minimising carbon emissions

Active chilled beams and opening windows so that the building can be ventilated mechanically or naturally.

A central core with a narrow floor plate to ensure working spaces are placed closed to the perimeter to utilise daylight during day lit hours. This has resulted in the innovation credit within the Hea 01 section which is highly unusual for a Grade A type office of this size especially within the City of London

The building’s envelope optimises the amount of natural daylight into the occupied office spaces whilst minimising direct solar gains.
