Chestnut Grove Academy

Project Description:

Chestnut Grove Academy in Balham was formed as Chestnut Grove School in 1986 with the amalgamation of Henry Thornton Grammar School and Hydeburn School. The campus is made of 3 detached buildings built over several decades; an original Victorian Block, the Main Building and the Arts Block. As part of the EFA initiative, the site will be redeveloped by demolition of the existing Main Building, construction of two new 3 storey teaching blocks, and the refurbishment of the existing Victorian and Arts Blocks.

The new teaching blocks have been designed to comply with the EFA’s Facilities Output Specification, with strong emphasis on the use of natural light and natural ventilation. Compliance is achieved with CIBSE TM52 overheating criteria through the extensive use of night cooling and exposed thermal mass. VZDV conducted extensive thermal modelling during the EFA client engagement stages and leading up to the planning submission to ensure the building’s form and façade design met the natural light and overheating criteria. 

Other energy efficient features include low energy lighting with daylight and absence detection switching, variable speed drives on pumps and fans, heat recovery on ventilation plant, BMS control and Automatic Meter Reading with energy monitoring and reporting facilities. 

The project is being delivered to BIM Level 2. 

Planning permission was obtained at the end of 2015, with the new building occupation in 2017.
