SE Controls helps create a stimulating learning environment at Passmores Academy

Passmores Academy in Harlow is using a natural ventilation system from leading smoke and natural ventilation specialist, SE Controls, to provide a comfortable and stimulating learning environment for pupils while helping to reduce the school’s carbon footprint.

Designed by Jestico & Whiles and constructed by Wilmott Dixon, the £23 million school provides places for 1200 students and uses an innovative design where five arms radiate from a 2.5 storey elliptical atrium ‘hub’, allowing access to the flexible teaching facilities and recreation areas from the common central area.

A range of low impact design features and sustainable technologies have been incorporated in the BREEAM ‘Very Good’ rated school, including solar shading, biomass boilers and energy efficient glazing together with the use of a natural ventilation strategy to improve and mange indoor air quality while reducing the need for mechanical cooling.

To provide the level of control and flexibility required for the school’s natural ventilation system to operate effectively within the pre-defined set points, SE Controls supplied and installed 7 OS2 control panels to operate the rooflights, atrium louvres and entrance screens.

In addition, the company also supplied and installed the rooflight and window actuators through specialist glazing contractor, English Architectural Glazing and were responsible for commissioning the complete natural ventilation system, which is interfaced with the school’s building management and fire safety system.

SE Controls’ Project Manager, Darren Wainwright, explained: “Indoor air quality in schools is a vital consideration as it not only manages the temperature within the building, but more importantly, the level of carbon dioxide present, which has been proven to reduce learning ability if it exceeds pre-defined national guidelines. Even the classrooms have CO₂ monitors fitted so that the level can be monitored and windows can be manually opened, if required.”

He added: “By incorporating natural ventilation and linking our control panels to the BMS, Passmores Academy can not only ensure that the air quality and environment is effectively managed but also that the energy costs are kept in check.”

Precision Ventilation Control for Sheffield University NAMRC

Precision window actuators from SE Controls are being used as part of an energy efficient natural ventilation system at Sheffield University’s Nuclear Advanced Manufacturing Research Centre (NAMRC) in Rotherham, to help maintain a comfortable environment for researchers and staff.

Work at the NAMRC focuses specifically on innovative research into metals and manufacturing engineering, rather than radioactive research and the new BREEAM Excellent rated building, which was designed by Bond Bryan Architects, is based around an open plan 5,000 m² workshop that incorporates cutting edge manufacturing equipment and facilities.

As the building already employs low energy and renewable initiatives, such as 320kW ground source heat pumps and a 900kW wind turbine, the use of natural ventilation was an ideal solution, as the temperature and air quality can be maintained within clearly defined set points while minimising the need for additional mechanical cooling.

To provide the high degree of control required, SE Controls, supplied, installed and commissioned a range of chain actuators, which are linked to the NAMRC building management system and are used to control the operation of the high and low level vents.

Twenty TGCO 24 15 actuators with a 350mm stroke length were installed on the building’s high level exhaust vents, while the need to protect against finger entrapment on the low level louvres prompted the selection of eighteen SE Controls’ TGCO 24 20 ‘Easi-Drive’ compact actuators each with 160mm stroke length.

SE Controls’ Project Manager, Darren Wainwright, explained: “It is absolutely vital that the natural ventilation strategy and system perform as designed to allow the right amount of fresh air to enter the building while ensuring that heat energy is not lost unnecessarily during the process. By using precision actuators to provide incremental operation of the system’s vents and louvres, it helps ensure that required performance is within the specified design parameters.”
