University of Otago Science One

The University of Otago Science One building is the home of Mellor Laboratories, a cutting edge space for students that includes a ‘super lab’ where they have access to the latest scientific equipment, along with offices, communal areas, and a seminar space.  The $56 redevelopment stripped a 47-year old building back to bare bones and then rebuilt it, turning the ageing space described by students as having a ‘rustic feel’ into a modern home of science where they can feel like a ‘real scientist’.

The 6500 square metre building required a new roof, exterior cladding and windows, and a tri-motor extraction system on the roof that shoots gas from the lab up to 50 metres in the air at such speeds that the Otago Rescue Helicopter Trust and Civil Aviation Authority had to be informed, as it could disrupt a helicopter flight. 

The need for more than adequate ventilation in such a space is both obvious…and maybe not so obvious.  For example, the new building includes three safety showers so students exposed to potentially dangerous chemicals can dose themselves down quickly and safely, a need that was made clear after a student found her clothes were dissolving on her.  With so many airborne chemicals and threats, the building required state-of-the-art equipment to effectively ventilate the area for students.  In turn, this equipment required ventilation for its optimal operation.  

On the exterior of the building, a bank of VL-2SD double bank weather louvres in a grey powder coated finish are used to provide ventilation and defense against the Dunedin rain.   Rated as Class A under BS/EN: 13030 for air volumes up to 1.5 m3/second and Class B for 3.5 m3/second, they are ideal for locations where high wind speeds and high levels of rainfall are common.  

The VL-2SD louvre blades are supported in a two-piece pressure equalised mullion system which is bordered by a 150mm frame that ejects captured water to the front of the panel.  It’s both simple and smart.  Importantly, it works very well and this is why this particular Ventuer solution has been used extensively across University buildings, hospitals, car parks and warehouses.  

Another reason for such extensive use is the adaptability of the system.  It shares the same support frame as the VL-3SD, VL-50CM and VL-100CM, and can be combined with these options in a cost-saving configuration if required.  Additionally, the standard frame can be fixed into a wide range of primary support structures and cladding types, including profiled metal classing, fibre cement sheet and window joinery systems.  

Also used on the University of Otago Science One building are Ventuer VL-50CM slimline screening louvres.  These have a low pressure drop and allow a maximum airflow with mechanical assistance.  However, it is important to note they are intended for areas where a low rain defense effectiveness is required.  This generally sees these louvres as a plant screen, while their unique minimal aesthetics makes them ideal for use on apartments and offices.  

The University of Otago Science One building is a wonderful example of how an existing structure can be turned into something altogether new and purposeful.  It’s a truly world class structure that puts New Zealand Higher Education on the international scholarly map, all ably assisted by what we consider the best ventilation products available.
