When it came to designing Littlehampton Academy, both the project’s architect, Architecture PLB, and the school wanted to create a comfortable space for students with an ‘open plan’ feel.
FDS Consult was tasked with creating a bespoke fire engineering solution for a 5,600sqm floor area, which is well above the maximum 2,000sqm compartment size detailed under the Building Bulletin 100 (BB100): design for fire safety in schools.
The FDS Consult team recommended a combination of systems including a sprinkler system, which are common in schools with areas spanning more than 800sqm, together with a natural smoke ventilation system – a component not usually required in a school environment.
This highly innovative ventilation system used existing windows at the ends of the building’s wings and at the head of the central voids to allow smoke to move from floor to floor and out through the clear stories – ensuring that regardless of the location of the fire, the smoke would not spread over a 2,000sqm area – using smoke venting methods to achieve the virtual compartmentation. This solution also enabled the school to achieve an open classroom door policy, meeting one of the end client’s main aims.
Alex Hutchinson, senior architect at Architecture PLB, said: “’FDS Consult’s innovative approach to fire engineering enabled our client to achieve their vision of a whole school building in excess of 10,000sqm as a single compartment without any cross corridor doors. This, combined with clearstory windows and wing-end glazing which could both be used for smoke venting, enabled excellent internal daylight and internal visibility- a primary client objective and an innovative approach to school design.”
Such instances of value engineering were also evident during the specification of the commercial sprinkler systems. While these usually require dual tanks, dual pumps, dual valves and zoning to conform to life safety standard, the FDS Consult team were able to engineer the system down to the exact size and specification of the sprinkler system required – resulting in the installation of a single tank and the removal of zoning, given that the school acts as a single zone. This system became a property protection system with life safety enhancements, satisfying both insurers and Building Control.
Michel Wizenberg, managing director at FDS Consult, added: “Working on a new build project from an early stage gave us opportunity to help the teams achieve design freedom while ensuring the safety of students and staff. In recommending a solution that goes above and beyond the usual requirements for fire safety in school environments, we were able to justify the design of a large floor area – providing cost savings for our client and a safe, functional space for the school.”
