Case Study - John Roan School, Greenwich

0 comments


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.

Case Study - Coppice Primary School, Wythall (2nd Phase)

0 comments

Airtherm have already completed the 1st phase works by installing two ‘Wind-iVent’ Systems to the newly completed single storey class rooms.

The 2nd phase fix features a further six 1.2msq units for the Hall area, which will be used mostly by the Church, and a further six 1.1msq units serving the Classrooms.

The new installation of fourteen natural ventilation systems for MVS Limited had been designed and carefully selected from the room data sheets provided, ensuring adequate ventilation rates for the pupils at Coppice Primary School.


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

Consultant: Stewart Associates
Client: MVS Limited
Sector: Education & Religion
Products: Wind-iVent Systems
Equipment: Natural Ventilation Systems
Application: Balance Terminals

Product Range
The Airtherm “Wind-iVent” Class ‘A’ is a natural ventilation system operating on established aerodynamic principles. As external wind flows around the terminal itself, positive and negative pressure areas are generated. On the positive side air enters the louvres of the terminal and is directed down through the internal vanes into the room below allowing a fresh air supply to be delivered, and on the negative side the stack draws the stale unwanted air which is expelled through the terminal into the atmosphere.

Manufacture
The units are be manufactured in accordance with BS EN ISO 9001, and to suit the architectural and design parameters as indicated in the design specification and drawings. Internal airways are to be protected by incorporating anti-bird mesh to the terminal louvers. Our systems can be manufactured to achieve 99.8% effectiveness (class A) when tested with a simulate rainfall of 75mm/hour and wind speed of 15m/sec based on a free area of 55%.

Installation
Units can be installed on almost every roof including flat, pitched and even on the roof apex where appropriate. The roof fabric of commercial applications has bearing on the openings and roof plates that are required to install the systems competently. We offer a roof plate solution for all situations, including self mount flashings and curb mount flashings with suitable upstands.

The features and advantages of the Wind-iVent: 

  • A fresh air supply for workers - proven to increase productivity & reduce staff sickness
  • Naturally ventilated - reduce your energy costs and carbon footprint without the need for mechanical ventilation
  • Night time purge of stale air - creating a fresh working environment for staff the following morning
  • Better control of building temperature and CO² levels
  • Free cooling
