Jestico + Whiles has won planning permission for this head office for the Community Housing Association in London's King's Cross. The 3,050m 2low-energy building is on the site of the temporary Almeida Theatre.
The scheme contains a central atrium, meeting rooms, interview rooms, office space and a main reception.
The sedum-planted roofing will provide both thermal and acoustic insulation, and the water contained in the sedum bed will help the evaporative cooling of the structure. A photovoltaic field generates electricity, solar panels pre-warm water and five large rooflight/vents provide passive stack ventilation extracts from the central atrium. A heat recovery system will extract heat using free internal gains from people, kitchen equipment and computers, and reuse the energy to pre-heat water all year round.The site has no car park, but the CHA is exploring supplementary sustainable transport options including battery-powered electric cars, which could be stored and recharged at a nearby site.
