Case Studies

Emmanuel College


In March 2018, Airway were tasked with replacing some of the air conditioning units at the University of Cambridge’s Emmanuel College. One of the larger colleges belonging to the University, Emmanuel College caters for around 500 undergraduate students, 150 graduate students, 90 Fellows and 150 members of staff. As such, there are plenty of people inside the college at any given time, and the temperature must be regulated and controlled constantly to keep students, staff and guests alike cool and comfortable.

We removed four old air conditioning condensers from the roof of the college, and replaced them. However, we didn’t install four new units: we installed one singular unit that boasted greater efficiency than the previous four combined. In addition, four commercial chiller units were installed in the basement, fed by insulated pipes which feed them with coolant. These chillers were then connected to the rooftop unit.

The old units were removed and correctly disposed of, with recyclable materials being sent for recycling.

The project was supervised by Matthew, our project manager, and Airway staff were present on site throughout the entire process. The college can now enjoy more efficient, effective air conditioning units!



Airway were commissioned to remove all existing equipment on the roof at Yamaha, Milton Keynes, so that major roof repairs could take place.

Upon inspection of the equipment, it was evident that the air handling plant was very old, inefficient and unlikely to cope with the stress of the crane lift off the roof. In consultation with the client it was decided that a new bespoke system was needed. A bespoke system was designed and installed to fit the customer’s requirements.

The original installation was extremely compact and poorly set out Airway completely redesigned the installation using a RoofPro plant support and access system. This allowed for efficient use of plant space and good access for future maintenance and service requirements.

The project was completed in multiple phases with the old equipment initially being removed to allow roof works to take place. After roof works were completed the new bespoke AHUs were installed along with a gantry system and platforms to ensure easy future access.

The final phase of the installation was to update the old Hitachi VRF air conditioning system to the latest Daikin VRV IV system. A centralised controller was then installed to allow joint control of both the ventilation and air conditioning.
