Heating & Ventilation Passivent CPD covers changes to BB101 in schools For specifiers involved in the design of school buildings, natural ventilation specialist Passivent offers a CPD seminar covering the imminent changes to the Department for Education’s Building Bulletin BB101. The new ‘Guidelines on ventilation, thermal comfort and indoor air quality in schools’ will see a number of key changes to the way air quality and thermal comfort are managed within school buildings. The new document will replace the current 2006 edition and will have a significant impact on ventilation design strategies and system choices. As a member of the BB101 advisory group, Passivent is ideally placed to provide guidance on the changes and how to achieve future compliance. Its recently updated CPD entitled ‘Natural Unique patented double-bank louvre arrangement, including insect mesh, combines maximum rain rejection with good airflow performance Actuator to modulate duct position for different ventilation modes Base unit constructed from marine-grade plywood from renewable forests Passivent Hybrid Plus Airstract ® ventilation system Low-energy sweep fan Ventilation in Schools & Commercial Buildings’ will include the key changes to BB101 and provide advice on the range of ventilation strategies available to enable specifiers to determine the correct strategy at the early design stage of a project. The CPD will also explain the association between BB101 and relevant Building Regulations as well as the importance of computational modelling to ensure a robust ventilation strategy. The CPD is free of charge and can be held at the client’s offices. To take advantage of the CPD, please contact Passivent on 01732 850 770, email projects@passivent.com or visit www.passivent.com/cpd Passivent is a specialist in delivering natural ventilation and daylight solutions and a leading UK company in the field of sustainable and energy efficient solutions.

Furze Down is a co-educational community school taking children from the ages of 5 through to 19, many with complex Special Educational Needs. Located on Verney Road, Winslow, the acoustic design ruled out openable windows for ventilation because of traffic noise. Average daytime background noise was 46 – 50dB at the external façade. Frankham Consultancy Group therefore specified AirMaster MVHR units because of their highly effective attenuation of external noise, 49dB. Further reasons for this choice were low specific fan power (SFP), quiet casing breakout noise and reliable temperature control. A total of 37 AirMaster units have been installed, comprising both AML 300 and AML 500 models, for use in class bases, life skills, media and nursery rooms. Units on the ground floor are connected horizontally to the outside through external walls, while those on the first floor are ducted vertically through the roof. Some units are partly recessed into void spaces while others are installed below the ceiling. As class sizes are relatively low, the units have been programmed to run at 80% of their maximum capacity, keeping casing breakout noise within the 30 dB(A) allowable under BB 93 for SEN facilities. The AirMaster MVHR units are zoned in ‘clusters’ and controlled via five control panels located in staff offices, thereby avoiding indicator lights in classrooms as these can upset children on the autistic spectrum. By using only short ductwork to connect to the outside, installation was straightforward with installation of each unit taking 3-4 hours only. All units came pre-programmed before delivery, helping commissioning to be carried out effectively. Demand control using integral CO 2 sensors ensures energyefficient operation and first class indoor air quality. www.sav-systems.com Furze Down classroom 24 Summer 2O17 <strong>4150</strong>
