space saving: • facade + roof top act as power generators, water collection + filtration • pipes and systems are located mainly between levels

The most prominent feature of PIXEL is the building’s facade. The panels are strategically placed to allow for maximum daylight, shade, views and glare control.
Environmental structural concrete PIXELCRETE with a lower embodied carbon
Double glazing low e coating insulated glazing

>>materials
Zero-waste + recycled ALPOLIC panels developed by Mitsubishi Plastics Composites Division
smart facade: • external planters create shading + grey water treatment • fixed shading louvers • double glazed windows • natural ventilation automated on a cool night • daylight glare control
06
Fresh air distributed into building
Gas powered heat pump produces heated air fed into floor space
Night time ventilation operated by smart technology
Water cooled ceiling-slabs allow for convection

>>air Exhaust air purged via exhaust risers
passive heating/cooling The use of passive cooling/heating ie. the shading facade, glazing, and insulating green roof compliment the systems in place.

Passive energy reduction schemes include ‘take the stairs’ decals + increased bike-parking spaces on site.

>>energy
Tracking photovoltaic panels follow the suns orientation throughout the day
energy harnessing: • roof top wind turbines • tracking PV panels • fixed PV panels • anaerobic digester

Rainwater collection via rooftop native grass
Rainwater is directed to the underground storage tank
Grey water is directed to facade planter reedbeds
METHANE GAS
Rainwater storage tank sends water through the treatment plant prior to human use

>>water Anaerobic digester uses methane to create energy
PIXEL has a self sufficient water supply and if Melbourne continues an average rainfall (for decade 1999-2009), could be disconnected from the mains supply.
Black waste from vacuum toilet system directed to anaerobic digester
Black water waste leaves site via sewer

Note: the building only works if occupied! The external plants on unoccupied level 2 were dried up from lack of toilet flushes = grey water.

>>future
‘Take the stairs’ energy reducing idologies
the future is now. Labelled a “future office”, PIXEL is a forward thinking sustainable approach to office buildings and is an answer for anticipating and adapting to change, rather than simply reacting.
