e-Bench logo.

Desktop computer tool for comprehensively measuring the energy, utility and environmental efficiency of a facility or process and comparing it to established benchmarks.

e-Bench enables organisations, industry sectors and even countries to improve energy, utility and environmental performance. It is a management tool that will create financial savings through reduced energy use and improved load management, and improve indoor environmental quality (IEQ) (and consequent staff productivity). It also enables organisations to achieve financial savings through picking up on errors in their supplier invoices and through additional process and production efficiencies as well as to more adequately meet the requirements of Triple Bottom Line reporting.

e-Bench has been designed as an interpretive tool suitable for use by everyone within an organisation from the Facilities Manager to the Chief Executive Officer and Chief Financial Officer. In New Zealand it is being used by their parliament, majority of it's universities and many local health authorities and hospitals. It is also in extensive use by many primary and secondary schools where it is not only being used as a means of invoice checking and monitoring consumption and improving energy efficiency, but also as part of the science and math curriculum. It therefore has to be understood by students as well as more technically proficient individuals. Screen Shots

Benchmarking corrections made in accordance with the UK Chartered Institute of Building Services Engineers (CIBSE) guidelines. Averages, best and worst parameters are derived from the sample. Validation of data entry is undertaken when populating the database.

Expertise Required

Populating the database with invoice consumption information is relatively straight forward, though collection and entering the facilities or processes attribute data requires a technical knowledge of the specific building or process, but nothing that an organisation should not already have available to them.


The majority of New Zealand's universities, many government departments, hospitals, schools, local authorities, property management companies and a number of key industry sector participants.


Public, commercial and industrial organisations that want to verify their suppliers invoices, monitor consumption, benchmark and make improvements in their energy and utility performance. Available internationally.


Required data on energy and utility consumption, e.g. from electricity, gas and water meters, physical attributes, i.e. the floor areas, construction of walls, floors, roof, their materials, thickness, orientation, shape, etc. and utilisation information, i.e. hours of business, internal temperature settings, occupancy, widgets produced, etc. It probably requires more initial data than any other type of database as it has been developed to truly compare apples with apples. However once this data has been entered it may require no further input from a user's perspective as the database has been configured to accept electronic batch files on consumption and data from production or building management systems automatically.


The range of outputs is limitless and is capable of being fully customisable by the user. It verifies and reports on any errors in invoices and / or any unexpected variations in consumption. It reports by individual buildings, process segments and provides it in an easily interpreted format of $, CO2 and kWh. It compares like facilities or processes against the sample average, best and worst and quantifies these differences again in $, CO2 and kWh. Information is available both graphically and in individual reports. There are a range of pre-formatted reports but a user can customise and configure it to suit any application or process.

Computer Platform


Programming Language

Java and Sybase database engine


e-Bench has been designed as a one-stop-shop capable of meeting ALL energy and environmental efficiency requirements. It is by default an energy management plan, an asset manager tool (maintains a register of facilities and their attributes), organisational tool (meets the environmental criteria for Triple Bottom Line reporting) and a financial tool (identifies and quantifies potential financial gains from efficiency measures and underpins their business cases).

e-Bench can include ALL energy sources, including electricity, reticulated gas, diesel, on site solar generation, biomass etc., and has been designed to perform the following main functions:

  • Checking, verifying and reconciling supplier's invoices;
  • Checking consumption patterns to ensure equipment and processes are operating as intended;
  • Identifying, quantifying and prioritising opportunities for improving energy and utility efficiency;
  • Monitoring and targeting of energy and utility consumption;
  • Assess performance contracts and determine if targets are being achieved;
  • Fulfilling the envisaged reporting criteria for the UN Global reporting initiative and Kyoto Protocol;
  • Identifying national and international best practice energy and environmental management;
  • Virtual audits of facilities and processes and, where data is available, of individual assets;
Planned extensions to the database will allow an organisation to:
  • Model impacts of changes to facilities or processes (e.g. addition of insulation) on energy efficiency;
  • Allow users and associations to define their own benchmarking indicators;
  • Interfacing with all asset and maintenance management systems;
  • Allow interfacing of demand response and demand management planning;
  • Allow Level Two Energy Audits to be largely conducted in the desktop environment.


No significant weaknesses-it can be used for virtually all tasks related to energy, utility and environmental benchmarking.
