KNX Technology has solved another challenge for St John’s College, a constituent college of the one of the world’s top universities, Cambridge.

Two KNX UK Association members have worked together to provide an integrated lighting solution to the college that was founded in 1511 by Lady Margaret Beaufort, mother of King Henry VII. Alumni of St John’s, a constituent college of Cambridge University, include 10 Nobel laureates, seven prime ministers, 12 archbishops, two princes and even three Saints, many of whom could only have dreamed of the efficient lighting and wokrig environment noe available to those that follow in their footsteps. 

We have already reported on the successful installation of KNX emergency lighting in the college’s dining hall in 2016.

This time, the focus was on installing an integrated lighting control solution for the college fellows’ accommodation as part of the rolling refurbishment of the New Court Building, which is listed under the Planning (Listed Buildings and Conservation Areas) Act 1990 for its special architectural and historic interest. The brief for the controls were to provide bettera lighting environment for building occupiers while reducing operating costs, respecting its architectural sensitivities, and minimising light pollution.

Cambridge-based Baulogic Limited, which specialises in the design, installation and maintenance of building control solutions, worked with building controls specialist B.E.G.  to carry out a detailed site survey. Taking into consideration the building’s unusual design, the project team selected the B.E.G wall mounted Indoor 180 KNX detector from the B.E.G. range of presence and motion detectors, one of the widest ranges available in today’s controls market.

Mark Gedrych, Director at Baulogic Limited, said: Most of the lobby spaces on either side of the central spiral staircase have tall cathedral ceilings, with archways between each area, neither of which we were allowed to touch.

“That’s why we selected the B.E.G. wall-mounted KNX 180 detectors for these areas, mounted at 2.4m off the floor, and chose frames that B.E.G. colour-matched to the paint which had been selected by interior designers Eve Waldren Design.

“The overall effect is very pleasing because the detectors blend nicely into the renovated 1830’s neo-Gothic spaces whilst still providing excellent coverage to catch Fellows and guests as they exit their rooms surrounding the lobby spaces on all sides.”

In a some locatons,  B.E.G. customised and supplied its ceiling mounted detector PD4 KNX SM, which gives coverage of up to 24m diameter. By fitting some of these detectors wit specially designed shields, they have successfully prevented lights being triggered when people are just walking past, rather than entering an area, reducing both energy consumption and unecessary light pollution.

Stephen Payne, Systems Sales Manager at B.E.G. said: “We enjoyed working with Baulogic to devise a tailored solution that provided the right lighting solution for this fascinating building.”
