Students at Loughborough
University’s recently completed East Park Design School building are being
helped in their studies by an integrated natural
ventilation system from SE Controls, which ensures that carbon dioxide (CO2)
and is kept in check and indoor air quality levels are maintained.
Designed by Burwell Deakins
Architects, the £14.7 million building uses informal design themes and layouts
to create an ‘inspirational environment’ as well as providing practical work
spaces, design studios, lecture theatres and workshops.
As with all learning environments,
one of the key considerations for the design school was ensuring that levels
remained within the appropriate limits to ensure that students’ abilities are
not impaired by poor indoor air quality. Also, the building was conceived form
the outset as a low carbon structure with minimum emissions, so utilises a
range of energy efficient technologies including solar shading, insulated
glazing and SE Controls’ natural
ventilation solution.
The extensive natural ventilation
control and actuation system was designed and installed by SE Controls to not only manage the CO2
levels, but also ensure the temperature within the building is maintained
within comfortable limits by using precise incremental control over the entire
natural ventilation system.
To achieve these key goals, SE
Controls installed over 400 chain actuators
over the ground, first and second floors to control high level vertical vents
in laboratories, offices and study areas, as well as the design school’s
workshops and computer room.
Automatic louvres are also
installed in ground floor public areas and meeting rooms, to allow fresh air to
enter the building, while a further 48 chain and linear actuators in the
building’s extensive glazed atrium vents provide ventilation to the atrium
space below.
The entire system is controlled by
a series of SE Controls’ OS2
networked control units and an OS2 modular panel for the atrium vents, which
are seamlessly linked into the buildings BMS. This not only monitors CO2
and temperature, but also signals the actuation of the vents and louvres to
maintain the levels within the system’s upper and lower set points.
Darren Wainwright, SE Controls’
project leader on the East Park installation, explained: “The close
relationship between CO2 levels and the performance of students in
schools and other educational establishments is already well documented, so
it’s vital that good indoor air quality is maintained. However, it’s equally
important that heat losses are minimised during ventilation to avoid unnecessary
use of energy to re-heat the building, which is why the operating algorithms
and ventilation strategy deployed minimise energy consumption while maintaining
excellent indoor air quality and comfortable temperatures.”
Loughborough University has also
been closely involved with the development of SE Controls’ new ‘NVLogiQ’
compact natural ventilation control solution through a highly active knowledge
transfer partnership (KTP) programme. The ongoing relationship, which has
already been in place for more than two years, has enabled SE Controls to
develop advanced energy saving operating algorithms to the current design
standards and accepted best practice for its new generation of controllers, of
which NVLogiQ is the first.
SE Controls specialises in the
design, project management installation and maintenance of advanced smoke
ventilation and natural ventilation solutions to meet the needs of architects,
contractors, building services engineers and facilities managers worldwide.
