Otago Polytechnic’s 231-bedroom Student Village is New Zealand’s tallest and largest cross-laminated timber structure. Designed by architecture firm Mason&Wales, the project represented a significant opportunity for the institute to incorporate some of the principles and philosophies of its Sustainability Frameworks, which are taught in its many sustainability courses. Named Te Pā Tauira, the development consists of two wings connected by a translucent circulation link and is situated within easy walking distance of both the campus and Dunedin’s vibrant city centre. Construction on this project was handled by Naylor Love, with windows from Altus Window Systems Fabricator Nulook Morlite, in Dunedin.  

This project followed objectives from the Living Building Challenge, meaning that sustainability was at its heart both in terms of the design and intended operation of Te Pā Tauira. The joinery selection considered energy conservation measures for lighting, heating and ventilation and was chosen to optimise thermal comfort while also offering a lightweight yet strong and corrosion-resistant material, that was also recyclable.

The project The choice of Altus Window Systems meant a wide range of configurations could be used on this project - from sliding doors and casement windows to curtain wall facades. For example, with an emphasis on passive design, the windows systems optimised not only thermal comfort and daylight but also natural ventilation. Preplanning for joinery installation was crucial as the materials for the project was largely delivered prefabricated. The windows had to be measured and fitted exactly so that the pre-finished cladding didn’t need adjustment and wasn’t at risk of damage. Huge attention to detail was required, calling on all of Nulook Morelite's 45-years of experience.

Three Altus Windows’ systems were used, meeting a combination of aesthetic and sustainability credentials:

• AllSeasons™ -  This was the main system. Over 350 Altus Windows AllSeasons™ thermally broken windows with Low-E argon-filled double glaze were installed to achieve the R values requirements. This structurally strengthened system uses well-proven pour and de bridge technology adding strength while reducing the transfer of cold or heat through the frame. This significantly contributed to Te Pā Tauira fulfilling its environmental objectives.
• Baltic Flushglaze 100 & 150 – Used in the stairwells and common room, this is New Zealand’s leading glass curtain wall solution. It brought to life the architect’s vision of a continuous wall of glass, all the while combining strength with optimal energy efficiency.
• Baltic Shopfront 75 & 100 – Used in the interior framework this product integrated seamlessly with Flushglaze and is ideal for the wear and tear expected in student accommodation. Although primarily designed for high use retail and commercial builds, Shopfront’s ability to fit with a wide range of architectural style means it’s perfectly at home in Te Pā Tauira.
  

The building fabric was designed to integrate high levels of thermal and acoustic performance, and all materials and finishes were selected considering the Living Building Challenge objectives and project budget constraints. Not every company can take on a project of this scale and come through it so effortlessly, but that’s why Nulook Morlite, Dunedin has been in the game for so long.

Te Pā Tauira, and the teams involved in its construction, have already won a number of awards, including:

• An Award of Excellence, the Resene Green Building Property Award
• An Award of Merit, the Arrow Multi-Unit Residential Property Award.
• The Hilti Projects $8-$20 million Excellence Award at the 2018 Building Industry Awards.

While they might never know it, the students who come to occupy the accommodation will have the team from Nulook Morlite Dunedin to thank for the exciting views, warm bedrooms and environmentally friendly nature of the residence they call home.
