Climate

205 Queensberry Street Melbourne, Australia

The Pixel Building is the only carbon neutral office building in the world. It was designed to be the greenest building in Australia as a prototype for building systems that will need to be regularly used in the future. This carbon neutral building is designed to generate more energy on site than it uses and over time will become a carbon positive building.

Melbourne is in the small temperate region on the south east edge of the country.The climate is much cooler and wetter then the rest of the country because of its location and the topographic changes in the region.

The Pixel Building is an office building designed for Grocon Pty Ltd. Designed to be a test bed for the building systems of the future the office has many experimental building systems to make it the "greenest building" in the world. Costing 6.5 Million AUD the 1136.4 square meeter (12,300 square feet) building has become worldly known for its performance as well as its aesthetics.

The site of the Pixel Building is in the heart of Melbourne, Australia. Capital of the state of Victory, the city is the second most populace city in Australia with a population of 4.25 million residents. Known as the "Garden City" innovation in sustainable design has become important to the city.

If Pixel is found to have the highest ranking for BREEAM it will be the highest ranked building in all 3 rating systems.

Effectively making it the highest ranked building in a collection of over 740,000 other buildings that have been evaluated using these systems.

FEATURES

A total of 30 fixed and tracking 215-watt solar photovoltaic panels are housed on the roof. Between them and the vertical wind turbines they can create enough energy to power the building.

The pixel building uses radiant cooling along with ammonia refrigeration. Radiant cooling is done by running cold water through pipes in the building which absorbs heat carrying it out of the building. In addition to this system ammonia refrigeration is used. Ammonia is a naturally occurring compound that breaks down naturally.

In addition to the radiant cooling and ammonia refrigeration the building is also set up to automatically open windows at night to purge the warm air and let in the cool night air.

"Pixel will also feature smart window technology, whereby windows will open automatically on cool nights to enable air flow into the building to cool the structure.” - Daniel Grollo

Anaerobic Digester and Vacuum Toilets

“… the Melbourne University designed 'living roof', which re-introduces Victorian grassland species to the Melbourne area …” -Daniel Grollo

The collected gray water is filtered in theses beds. Then it evaporates, is sent to the underground tank, or is sent to the city's sewer. Not only do they serve to filter water but they also shade windows providing cooling

"We believe that Pixel truly is the office of the future and one of the most sustainable buildings in the world." - Daniel Grollo

The vacuum toilets, similar to the ones used on planes, uses only 0.13 gallons per flush compared to the 1.28 gallons per flush used in an efficient conventional toilet. Because so little water is used the solid waste is able to be collected and used to produce methane gas that can be used as fuel to heat the building’s water.

"The distinctive looking sun shade system on the exterior of the building will provide the maximum amount of daylight into the office space, while protecting it from too much glare and heat in the summer.” - Daniel Grollo

Not only does this facade allow the building to be daylight without glare but it creates a unique personality for the building

The concrete used in the project incorporates a large amount of recycled and reclaimed aggregates in its mix. The concrete called Pixelcrete cuts the embodied carbon in half.

"The building is water balanced, so it doesn't need a connection to the main water supply, even when you have 80 people working in it and using showers," Zimmerman says.

The building was designed to be almost water independent. The roof garden and ledges collect and filter water that then is collected in the underground tank. The collected rain water is used in all the faucets, toilets, and showers in the building with the exception of one tap that is connected to the city supply to provide drinking water only. According to historical rainfall the building should be able to collect all the water it needs.

"We also have the world's leading wind turbines, invented in Bendigo …” -Daniel Grollo

Three 1.5-kilowatt vertical axis wind turbines, created for this building, are found on the roof
