Modelling air quality, traffic emissions and energy use

NIWA has developed an integrated framework that will enable urban planners in New Zealand to quantitatively incorporate air quality, traffic emissions and energy use as evaluation parameters to develop and implement growth strategies. We’ve called it TOTUS (towards sustainable urban forms). We intend that a tool incorporating environmental, health and energy related parameters into the decision-making process will support better urban development management practices.


During the next phase of research, we are focusing on demonstrating the features of the system, and working towards wider availability of the service, via a series of projects.
