HOK London awarded UK’s first LEED CI Gold certification for London office
HOK London has achieved LEED Commercial Interiors (LEED-CI) Gold certification for its newly designed office at the Qube, in Central London – a UK industry first. Established by the U.S. Green Building Council, the LEED Green Building Rating System is a voluntary international standard for developing high-performance, environmentally conscious buildings and interior spaces.
Completed in 2009, the open-plan layout of the interior incorporates numerous breakout and conference areas, allowing staff to work flexibly, creating an inspiring and collaborative atmosphere. Shashi Narayanan, Head of Sustainable Architecture at HOK London said: “Our challenge was to achieve a high LEED rating within normal budgetary constraints for a commercial office interior. By applying the LEED certification to our own office, we have been able to demonstrate that environmentally conscious design can be affordable and achievable in commercial office spaces.”
Within the design process, HOK London considered the recycled content of materials achieving 32% of the total project cost, choosing regional materials (37% of the project cost) that reduced the transportation distance of materials to the site. The sustainable provenance of all timber used was verified at 72% by using FSC (Forest Stewardship Council) certified wood products. The percentage of materials containing rapidly renewable content (such as sheep wool) achieved an innovation in design credit, and the energy usage requirements of equipment used in the project were chosen to mitigate against adverse impacts on the environment. Materials, finishes and furniture with low formaldehyde and VOC’s (Volatile Organic Compounds) were also specified to improve interior environmental air quality.
