Buntingford First School is the first newly built net zero carbon school in Hertfordshire that offers 330 places and 10 classrooms for students aged 5 to 11. The school will support the families within the 1,500 properties that are currently being developed in Buntingford. Pentalec successfully delivered electrical and decarbonisation services for this Design and Build contract on our first project with Morgan Sindall as the principal contractor. The school was designed to Passivhaus standards to reduce emission intensity, improve air quality, and lower energy costs in line with Council’s sustainability strategy.
