Sector
Education
MEP design for schools, colleges and university buildings, including ventilation, acoustics and laboratory services.
OVERVIEW
Education buildings have high, sharply peaked occupancy and low tolerance for services noise, which makes ventilation the central design problem: the rates required by occupancy are substantial, and the acoustic limits mean they cannot simply be met with more air velocity.
University buildings add a further layer where laboratories are involved, with containment, fume extract and resilience requirements that do not appear in general teaching space.
DESIGN
What drives the design
Ventilation against acoustics
Teaching spaces need high fresh air rates and low background noise at the same time. Meeting both means larger ducts, lower velocities and attenuation designed in from concept, not added when a test fails.
Occupancy is peaked and predictable
Unlike an office, an education building is close to fully occupied for defined periods and near empty otherwise. Controls and plant selection should exploit that rather than treat it as a constant load.
Robustness and maintenance access
Fittings and controls in teaching and circulation space need to survive heavy use, and maintenance access has to work around a term calendar rather than a normal shutdown.

QUESTIONS
Common questions
What ventilation rate is required in a classroom?
BB 101 sets the ventilation performance standards for schools in England, based on maintaining carbon dioxide concentration limits rather than a fixed air change rate. The design has to achieve those limits while staying within the background noise levels set by BB 93, which is the constraint that usually determines the system.
