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.

The team here at Airway Group worked alongside Fleming Construction and a variety of specialists, including designers, consultants and manufacturers, to complete a comprehensive air conditioning system installation over fourteen weeks.
We installed two separate Mitsubishi HRV systems with three hybrid internal boxes and twenty-six internal cassettes covering the entirety of the building. The various control systems were designed to create different environments for a variety of buildings, including showrooms, offices and training rooms. We employ only the highest health and safety standards, especially as our team were working at a height for the majority of the project.
At Airway, we are always thrilled to be working on new and exciting projects like this and enjoy collaborating with other companies to create systems tailored to the businesses exact needs.

Ely Archives


In 2019 our team had the pleasure of working with Ely Archives by installing a brand new air conditioning system and a close control system, giving users complete control over the temperature and humidity of the building. Our work ensured our clients were able to maintain the correct environment to continue to preserve the state of the historic records and other resources related to the history of Cambridgeshire.
The old units were removed and correctly disposed of, with the recyclable material being recycled through the proper channels. The entire installation was completed within three months, all at a competitive rate, so Ely Archives could resume work swiftly. Here at Airway Group, we were immensely proud of the work we completed, as we added a variety of technology to the building, including heat recovery ventilation, circular diffusers, Daikin wall-mounted air conditioners, among many other things.

Arm Ltd


In May 2019, Airway had the task of removing gas boilers from the roof of a building using a crane to make room for new boilers at ARM Ltd, an architecture company based in Cambridge. Our staff worked under strict health and safety procedures to ensure the safety of our own staff and the staff from Intech Environmental, who were working alongside us for the duration of this project.
We removed the old units and correctly disposed of them by recycling the proper materials, whilst our installation team were able to get on with installing the newer models. Our experienced team unpacked, roped up and hoisted the gas boilers onto a crane and carefully manoeuvred them onto the roof of the building.
The team here at Airway were delighted to work on this project, using our decades of experience to complete the job to the highest standard and in a timely manner.
