Case Study - Ashmount SEN School, Loughborough

Airtherm Engineering have recently completed the installation of two natural ventilation systems at Ashmount SEN School.

Working closely with Derry Building Services Limited (based in Newark), Airtherm designed and selected the correct systems to serve the new school hall. This process required critical information to establish the correct airflow and terminal size and a close working relationship with both Derry Building Services and Leicester Council.

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.

Product Range
The Airtherm “Wind-iVent” 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%.

The features and advantages of such a system:

• 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
