Dunnings Engineering Services and GridZero will launch NUFAD Negawatt Under Floor Air Distribution system at the air conditioning, refrigeration and building services expo, ARBS 2008 , at the Melbourne Exhibition Centre, April 21-23.
The NUFAD Negawatt Under Floor Air Distribution system takes a highly innovative approach to air cooling and heating by coupling a patented energy colour indicator, the GridZero Orb, with advanced air distribution and energy storage to save between 30% and 60% of typical energy consumption.
The NUFAD Negawatt Under Floor Air Distribution system has been designed and manufactured in Australia to provide significant energy savings and demand management in both new buildings and retrofit buildings looking at Greenstar upgrades.
The raised floor design makes it easy to incorporate individual workstation controls and monitoring equipment to enhance energy savings. A building owner can install personal air-conditioning stations at each workstation, cooled by air displacement from the raised floor system.
Air displacement can save between 30 and 60% of energy depending on local climate conditions, according to the Intergovernmental Panel on Climate Change Panel (IPCC) Building Report.
ARBS visitors will be able to view the patented energy control solution for the The NUFAD Negawatt Under Floor Air Distribution system in operation. The negawatt energy batts installed in the floor work in conjunction with a glowing GridZero Orb. The Orb changes colour to red when demand management is in operation, blue when energy is cheap, and green when surplus renewable energy is available.
The kilowatts of energy saved are measured using a real-time web-based system. This simple, real-time colour system makes it incredibly simple and absolutely clear to end users when they are using cheap green power or expensive dirt power.
The combination of clean under floor air distribution and green negawatt controls can deliver a nett-zero carbon environment to building owners.
The raised floor systems incorporate phase change material (PCM) thermal storage to effect greenhouse energy savings and maximise use of renewable solar power. The NUFAD Negawatt Under Floor Air Distribution system will be showcased alongside green AC/DC wiring cable and power systems.
Together, these features can make a large contribution to upgrading an existing building to a 5 star energy rating.
Dunnings general manager, John Gill, said his company recognised the need to move from the industrial age to the climate change age.
"We have been around for nearly six decades, and we intend to be around for the next six," John Gill said. "We are committing R&D resources to develop environmentally friendly products and our aim by attending ARBS is to research the market for climate change.
"We plan to be the leading prototyping engineering service for climate change, servicing both Australian and export markets. The NUFAD innovation is the first of many to come from Dunnings."
Dunnings currently supplies hundreds of products for the building and hardware industries from its Adelaide factory at Dudley Park, South Australia.
