Benchmarking Normalizations

e-benchThere are five levels of outputs available in the benchmarking:


  • Level 0 is benchmarking against industry standard average EUI and best practice;
  • Level 1 to 5 is benchmarked against the e-Bench™ sample.
  • Level 1 to 5 have additional layers of normalization for climate, utilization, construction and equipment load.

This staged benchmarking allows a user to determine if the inefficiencies are due to how the facility has been constructed, the way it is being managed or from the type of functional equipment being employed.  This is a very powerful feature for a user, as it allows them to both cost effectively monitor the performance of the facility and allocate resources into areas with the greatest scope for improvement.

Whilst there is some initial work in establishing the benchmarking configuration, it is however a one off task.  It is assisted by having a computer aided drawing tool that can be used in conjunction with a building library and pre-loaded construction material with their R values available and ready to populate the database.

What e-Bench™ does is to model exactly how the building or facility might operate in terms of thermodynamic flows through its building fabric.  Consideration is given to factors such as heating/cooling gains or losses, hours of use and how it might be utilised.  e-Bench™ analyses these in the context of the function that the buildings is being asked to perform and the type of equipment a user may have installed to carry out this designated functionality.

The results from the benchmarking analysis are then compared against the minimum standards as laid down by the various building authorities.

The information may be viewed using our secure web-site or alternatively the data can be used to feed into a dashboard that will display how well the facility is performing and how it compares to the building code standards and to other facilities in the e-Bench™ database.
