Case Study - Tipton Hospice, West Midlands


Airtherm Engineering have recently completed the new installation of a natural ventilation system at Tipton Hospice for local firm Cockbill Grant Limited (based in Rugeley, Staffordshire). Airtherm beat our local competition based on our knowledge, experience and technical ability providing detailed design proposals for the client’s consideration.

The Wind-iVent units selected for the project were based on technical information provided by the client, which consisted of room volume measurements, occupancy level, heat gains and the geographical location of the building. Our computer aided calculation package selected the optimal size to match the information inputted by our technical engineer, ensuring optimum performance of the application and satisfaction for the client.

All of our natural ventilation systems are designed in line with current publications such as CIBSE guidelines, AM10 Natural Ventilation in commercial buildings and Building Bulletin 101. The terminal sizes are selected by our new computer aided software ‘Wind-iCalc’ and fully conform to the CIBSE requirements.

Case Study - John Roan School, Greenwich


Airtherm have installed a new Wind-iVent natural ventilation system at John Roan school in Greenwich, London. Founded in 1677, the John Roan School is one of the oldest state schools in the country, with a rich and distinguished past.

Having recently received funding under the government’s Building Schools for the Future initiative, the school is on the cusp of opening the doors on one of the UK’s most innovative, fun and flexible learning environments - a new, modern sports hall project, where the natural ventilation system was installed.

The complex will house four badminton courts, one indoor tennis court and a basketball and volleyball court with space for 5-a-side football. There is also a separate activity studio where Zumba and dance classes can be held, which will take PE lessons to a new level at the school. A natural ventilation solution like the Wind-iVent will ensure a constant fresh air supply for occupants, the efficient removal of unwanted CO2/stale air and a suitably heathly environment for activity.

The John Roan has been dedicated to serving the community of Greenwich for more than 335 years and
Airtherm Engineering have been proud to partake in the development of the brand new, state-of-the-art 7,600m2 building at Westcombe Park. This, along with a fully redeveloped facility at Maze Hill will make John Roan one of the largest schools in the United Kingdom.

Wind-iVent Installation
The Wind-iVent units are lifted by a specialist crane company who work closely with our on-site engineers. The systems are mounted onto the 3mm thk aluminium fully insulated roof upstands. Each unit is fixed and secured to not only the upstand but internally using universal type fixings.
Once each unit is secured a low-leakage uPVC damper and 24v actuator is fitted, followed by the insulated plenum and an internal powder coated grille to complete the system.
