The Sedum

The unusual roof on our Science & Technology building in Leybourne Park arouses the interest of many passers-by. Ours is one of the few Sedum roofs in the borough and it is anticipated that we will see more of this type of environmentally friendly roof in the future. The roof aims to reduce heat absorption in the summer so lowering the need for air conditioning and at the same time to provide insulation in the winter reducing heating costs.

This eye catching roof also retains and reduce airborne dust, helping to filter and improve air quality, by attracting particles to the damp surfaces of the vegetation and soil. The plants on the roof absorb gaseous pollutants through their leaves and even offer sustainable habitat for plants and wildlife. Additionally, they act as a sound barrier, contributing towards noise reduction. Many of the materials used in this type of green roof construction are manufactured from recycled building materials, plastics and rubber, which reduces landfill disposal.

Ventilation in our building is being delivered by low-energy natural ventilation – saving in both capital equipment and running costs, and it provides environmental benefits by reducing energy use and cutting greenhouse gas emissions. A successful achievement for Kew College, the residents of Kew and the environment!
