In the context of reducing household greenhouse gas emissions, in-home energy feedback displays have been trialled as a mechanism to assist households to monitor and change energyuse behaviour. As we move towards technologyrich zero-energy homes, the challenge of managing energy use and electricity generation systems will increase and a new role for in-home feedback displays may emerge.
The Nationwide House Energy Rating Scheme, commonly known as NatHERS, which is applied through software tools such as AccuRate Sustainability, has become the predominant pathway for complying with energy efficiency requirements within the National Construction Code of Australia.
Deploying standalone solar air-conditioning systems in residential buildings forms a radical demand-side energy management solution for eliminating the peak electricity demand from residential air-conditioning. For existing grids to meet this demand a correspondingly major investment is required to extend the capacity of the infrastructure.
Since 2010/2011 changes to the national construction code require newly constructed houses to perform at a minimum Nationwide House Energy Rating Scheme (NatHERS) energy rating of 6 stars (or BASIX equivalent in NSW), which determines the predicted thermal energy a house requires to maintain thermal comfort, given its location.
Distributed electrical energy storage can help reduce the CO2 emissions associated with the use of electrical energy, better enabling distributed generation of energy from sources such as rooftop photovoltaic (PV) systems.
