Bespoke rooflight design creates a more effective learning environment
When the time came to create a new-build extension, Northbrook College seized the opportunity to refurbish its engineering block. Existing clerestory windows were leaking air and rainwater, overheating was an issue and the contractor needed specialist design input into rooflight curbs for the new build which could achieve a large reveal depth through the roof, and allow rainwater runoff.
The consultancy and solution
Our team was brought in to revise the existing plans for both new build and refurbishment phases, where previous designs had fallen short on standards and budget. We were asked to provide solutions which would suit the architect’s aesthetic ambition, limit solar gain, improve acoustic insulation, and meet the M&E consultant’s predetermined calculations for free-flow ventilation. We consulted with the entire project team to draw up proposals, fine-tune and present final design drawings which met both brief and budget.
In phase 1 – the new build – we provided contemporary circular daylight solutions to dining and corridor areas, including units more than 3 metres in diameter. In total, 12 Em-Glaze modular circular glass rooflights on bespoke aluminium fabricated upstands flood the interior with light. The larger units were cleverly manufactured as multi-section units for simpler transportation and final assembly on site.
In phase 2 – the refurbishment – we installed 19 bespoke Em-Glaze shedlights which met the architect’s vision and replaced the leaking clerestory windows. The vertical side incorporated electrically operated vents for ventilation – all shielded from prevailing winds. Our glass specification manages solar gain, meets U-values and maximises daylight. Nine Em-Tube tubular skylights are now daylighting the internal corridors.
