ECO Optimiser

ECO Optimiser calculates the score for all the possible combinations of measures and compares their scores to display the order that maximises the results. The order of measures, which can give the maximum ECO score, can be different for different properties.  

The ECO Optimiser helps you to maximise income at various stages:

  • The project planning stage when you can influence the order in which measures are installed
  • When multiple measures have been installed on the same day and you have total control over the order in which the measures are scored
  • When multiple measures being scored are reported as having the same date of completion. 

ECO Optimiser is an add-on to ECO Online but use of this is included in your normal transaction rate.
