New modelling tool to help reduce Auckland’s greenhouse gas emissions

04 April 2016

University of Auckland researchers have developed a new modelling tool to identify the most productive areas for residential solar installations. This is the result of a collaboration between the Department of Engineering Science’s Dr Tony Downward and the Business School’s Dr Kiti Suomalainen.

The 3D geographical computer modelling tool, which is the first of its kind in New Zealand, will provide data on the solar rooftop potential of individual houses. It features data such as the carbon footprint of buildings, the effects of nearby objects and topography, and has now been tested on about 500,000 homes in Auckland.

Dr Downward believes that this new technology can help the Auckland Council to meet its goal to reduce greenhouse gas emissions to 40 per cent below 1990 levels by 2040. The mathematics confirm this – Dr Suomalainen believes that this is achievable if half of the tested homes begin to adopt 36 square-metres of solar rooftop panels.
