Mr Creemers says the buildings offer tenants a stylish space that will have only one-third of the overheads. Environmentally-friendly design elements like the courtyard for natural light, the solar panels for hot water and the natural ventilation to replace air-conditioning promise to make the space a more affordable choice in the long term.
With seven retail or restaurant spaces on the ground level and 5000m2 of office space spread over five buildings, the new complex is filling up prior to the opening on September 1.
Creemers'company was behind the Iron Bank building on K road, which received a 5 Green Star rating from NZGBC. He says that going green usually means 10% added building costs, but those are recouped between 4 - 7 years after completion from energy savings.
One of the most distinctive features of the Geyser building is the exterior composed of thousands of glass panels that open to create airflow. The two layers of glass create channels for ventilation or buffers from the cold winds to keep it warm.
Despite the ultra-modern feel of the complex, its energy-saving design elements are simple and proven technologies.
"None of the innovations at Geyser or overly complex or prohibitively expensive," says Ms Cutler.
"This is about creating a thermal envelope and thermal ventilation. Similar systems could easily be adopted by other projects across the country."
The Geyser building is located at 100 Parnell Rd.
Trailblazer
The New Zealand Green Building Council has awarded the Geyser building a 6 Green Star rating, only the second building in the country to achieve this benchmark after the Christchurch Civic Centre.
The rating indicates that the building has attained the highest standards for sustainable design. NZGBC CEO Alex Cutler says it's not just about reducing costs through energy efficiency.
"Businesses here will be making a statement about their commitment to staff, customers and the planet," says Cutler.
"Much of the focus of green buildings is on benefits such as energy and water savings but just as important is the quality of the working and living environment."
According to Cutler, over 600,000m2 across the country have already been certified with their matrix and all schools are now required to get a 5 Green Star rating. Ms Cutler says that international research shows improving the quality of the workplace boosts productivity and reduces sick days.
Geyser Description
The Maori name for New Zealand; Aotearoa , Land of the Long White Cloud, is bound up with a pre-European view of peoples connection with their environment and Geyser is one of a series of building designs by our firm using this attitude. The series approaches people, architecture and environment as interlinking identities and is underpinned by the assumption that if a building logically belongs in its environment, then the people that use the architecture will feel they logically belong there also.
The program called for an office/retail mix set above an automated car stacking reservoir. This floor area has been condensed into five separate sub buildings, around a lane way pedestrian system, this allows for passive lighting and environmental control for each tendency via an automated pressurised ring facade. The façade is a computer automated twin wall system forming a mirrored inifinty box, this shelters and capitalises from the strong winds and solar energy available to the site. The box opens and closes according to sun and wind information to provide preheated and cool air convection across each habitable space according to the day. Occupants can feed into the system via the manually operated inner facade with an overall energy monitoring system providing feedback on the efficiency levels achieved.Computer modelling suggests there is a brief early morning period mid winter, where the building passive climate control will need counter balancing with applied heat energy. This has been supplied by a night storage unit.
Facts: New Zealand's first 6 Green Star - Office Design rated building. The design incorperates Solar water heating, grey water recycling and natural ventilation.
Floor area is 5040 sq m. This is broken into Ground floor retail and three floors of office space . There are five basement levels with 165 car parks, serviced by an automated car staking system.
Designed to use 27% of the energy of a typical building its size.
Requires only half the artificial lighting of a typical retail/office building (6 watts per square metre)
Geyser uses half the water of a typical retail/office building of its size
The individual sub-buildings, centered around a pedestrian system of courtyards allows significant light and air penetration to a great percentage of the lettable space.
100% fresh air to occupants (as compared with the average of 25% for air-conditioned buildings in New Zealand)
70% of building waste recycled
