The innovative Freshvector combined perimeter heating and natural ventilation system from Dunham-Bush is being used to provide space heating in two new buildings at The King's School in Peterborough. Freshvector uses specially developed vents with motorised dampers and attenuators in the wall of the building to allow fresh air to be drawn across the high level heating elements using the stack effect. As a result, the fresh air is pre-heated and draughts associated with conventional ventilation are eliminated, while noise levels are very low.
Founded in 1541, The King's School is a voluntary aided Church of England comprehensive secondary school, with a large academic Sixth Form. Recently, the school has extended its facilities with the construction of a new Sixth Form centre and a new humanities block. The services for the building were designed by consulting engineers WSP.
"Sustainability and energy efficiency were key criteria in the design of the new buildings and we were also keen to maintain low noise levels in the teaching spaces," recalled WSP's Rob Clarkeson. "The Freshvector system meets all of these criteria while also providing demand-controlled ventilation in line with the requirements of Building Bulletin 101 (Ventilation of School Buildings)," he added.
The dampers on the Freshvector vents are controlled automatically, initially by carbon dioxide levels in the space and with some local override facility. If required, sections dedicated to fresh air heating load and building fabric heating loads can be controlled independently.
The school's general manager Drag Crnomarkovic commented: "The new buildings have been well-received by students and staff and we have been very pleased with the heating in the classrooms and the fact that it supports our commitment to sustainability."
