Have your say on co/trigeneration in NABERS Energy ratings
NABERS is seeking industry submissions on its proposal for how cogeneration and trigeneration systems are dealt with in the NABERS Energy rating as outlined in a position paper released this week.
“The position paper, Proportioning of Energy used by Cogeneration or Trigeneration Systems is open for industry comment. NABERS is seeking industry submissions on this proposal for how cogeneration and trigeneration systems are dealt with in the NABERS Energy rating.
“According to acting deputy CEO of the Office of Environment and Heritage, Bernard Carlon, co/trigeneration systems have become increasingly popular over the past few years as a means of reducing a building’s environmental impact and costs.
“We are seeing an increasing change of focus in new developments from single building energy systems to the planning of green precincts that have district-scale energy systems shared across a number of sites,” he notes. “For example, the City of Sydney’s Decentralised Energy Master Plan proposed the roll out of trigeneration precincts and the intent to connect over 360 MW of building electricity demand.”
To reflect this changing trend, Carlon states that a review of NABERS rules would consider how externally supplied electricity and thermal energy from these plants could be accounted for by the NABERS rating system. “NABERS exists to encourage and reward environmental performance so it is important that we aim to reflect the true environmental benefit of co/trigeneration systems in a NABERS energy rating,” he imparts.
The position paper outlining the proposed changes to the NABERS Ruling is available on NABERS’s website. Submissions will be received until close of business 24 August 2012.
