A BUILDING WITH 'GREEN' PLANTED WALLS AND A 'BROWN' ROOF
The children's centre benefits from the use of natural daylight and ventilation, recycled rainwater, 'brown' roof covering and 'green' planted walls on the north-west and north-east facades. It is two storeys high, except for the single-storey café/reception at the south end, which is sheltered on two sides by an overhanging roof and anked by a two-storey green wall.
The building has a cavitywall construction. The green wall planting panels are fixed to a waterproofed outer leaf of 100mm concrete blockwork; on other facades the blockwork is lined with a proprietary external render system and timber panels. The inner leaf is insulated timber studwork faced with plywood and a double layer of plasterboard. The 'brown' insulated at roof is covered with a layer of rubble, between 125 and 150mm deep.
The roof will be covered with a layer of self-seeded plants.
The green wall panels, containing black filter foam, growing medium and irrigation pipes, are fixed back to the building structure. The exposed edges of the wall are capped by a preformed polyester-powdercoated aluminium coping.
The output from the gutters below the green wall and the rainwater from the at roof are directed to a harvesting tank and recycled via a pump system to irrigate the green walls.
