We utilise our experience and expertise in sustainable design to optimise site potential and planning, minimise energy consumption and reduce waste, protect and conserve water, utilise low-carbon materials, design for future flexibility and provide for safe and simple operational and maintenance practices.
Our sustainable design philosophy encourages decisions at every stage of the design process that enhance the wellbeing of occupants and reduce negative impacts on the environment. Our integrated, holistic approach ensures sustainable outcomes and positively impacts all phases of a building’s life cycle, including design, construction, operation and decommissioning.
The Campus Hub and Library project realises Victoria University’s vision to create a heart for the social and learning activities of the campus in a connected, transparent and welcoming environment. The new Hub building occupies the previously underutilised Quad and connects the refurbished Rankin Brown Library, Easterfield and Maclaurin Buildings. Sustainable principles are fundamental to the organisation of key elements of the Hub ensuring the holistic integration of daylighting, natural ventilation and adaptability of space. Important environmental and social benefits are brought to this project by the adaptive reuse and revitalisation of the existing buildings.

The concept for this seven-level workplace development is a relaxed stack of floor plates around a connecting atrium which allows daylight to penetrate deep into the building.
The building’s deep plan results in a favourable low surface to volume ratio. The large floorplates (typically 2200m2 ) receive ample daylight through the glazed façade, supplemented by the top lit atrium.
The relaxed stack of floorplates creates floor projections and overhanging storeys that reduce solar gain to the east, west and north façades. The north façade benefits from its shading by the adjacent Datacom building.
The atrium with its occupiable bridges and connecting stairs encourages social interaction within the building, reduces reliance on lifts and offers views to the mature London plane trees of Victoria Park. Locating the atrium on the south façade permits glare free daylight to enter deep into the building. A fritted glazed skylight located at the top of the atrium brings in additional light.
A unitized curtainwall system with high performance glazing provides a durable, low maintenance façade and conserves energy use by reducing both heating and cooling demand. The staggered building edges include an outdoor terrace and balconies that blur the boundaries of a traditional workplace and allow occupants to be outside without leaving the building.
The roof embraces sustainable design principles in several important ways; rainwater is harvested from it for grey water use; roof-mounted PV panels generate power for on-site use and the warm roof build-up completes the building’s high performing thermal envelope, reducing demand on mechanical systems.

The University of Auckland
Grafton Hall provides pastoral accommodation for over 300 University of Auckland first year students. Three mid-rise buildings are arranged around a series of open spaces and courtyards that relate to both the functional arrangement of the site and its orientation.
Single aspect dormitories on a double loaded corridor provide optimal and cost effective planning efficiencies but create greater challenges for passive ventilation which typically relies on cross ventilation. Through detailed thermal modelling analysis, a natural ventilation solution was developed for this project that utilises a combination of opening windows, internal ceiling fans, external shading, and low-E glazing to eliminate the need for air conditioning. High levels of thermal insulation, including a warm roof, use of daylight and LED lighting throughout also contribute to the low energy demands of these buildings.
The site is well located, being close to the motorway system, Grafton Rail Station, bus routes and is within walking distance of Auckland University’s Grafton, Newmarket and City campuses . A secure bicycle storage facility with electric bike charging points is provided for students and staff.

Wynyard Central is a mixed-use development within the Wynyard Central Precinct, an area of Auckland’s waterfront undergoing regeneration from an industrial port area to an inner-city live-work neighbourhood. Wynyard Central is an exemplar project for this precinct, providing a variety of housing typologies, retail space and public open space established on a strong commitment to sustainable design principles.
The site layout and building forms were developed specifically to increase solar penetration and ventilation into the dense urban block arrangements. Consideration of the local microclimate, access to natural ventilation and daylight, thermal mass and shading have driven the final building form and fabric. Dwellings are strongly connected to their external environment with a high degree of passive control and generous covered balconies and terraces for outdoor living. The provision of multiple cores enables through apartments that utilise passive cross ventilation.
