Energy ResolutioNZ (ERNZ) has a very powerful, patented energy & utility management Software as a Service system available known as e-Bench™. Developed and supported by Energy and Technical Services Ltd, it is also known as Enterprise Energy & Carbon Accounting (EECA) software.

e-Bench™ has an impressive range of functionality that includes targeting and monitoring, invoice reconciliation, management reporting, carbon emission tracking & reporting, continuous commissioning, benchmarking and simulation. This combination in a single integrated software system makes e-Bench™ internationally unique. To the best of our knowledge e-Bench™ is the only asset-centric energy & utility management system of its kind.

e-Bench™ is configured to be viewed as either a dashboard or as a full version. This flexibility means it is suitable for use both by a non-technical and technical or proficient user, in other words by anyone within an organization irrespective of their skill level.

Key Benefits of e-Bench™
The key benefits to an organization from having e-Bench™ as their sustainability management system is that it is a completely integrated package with the data upload and management being part of the service offering.

This means that the organization is free to use and act on the intelligence from e-Bench™ rather than have to focus on the sourcing and upload of data into the system. This therefore means the energy and utility management professionals get to maximize their skills where it is of most benefit to the organization and that is on driving efficiencies from optimizing the performance of the business and assets.

Subscribing to e-Bench™ more than pays for itself. Real financial savings and avoided costs easily justify the benefits of having a sustainability program. These benefits are automatically captured and can be easily relayed to stakeholders, staff and senior management.

In addition to real financial benefits, there are further reputational benefits associated with e-Bench™ such as from Corporate Sustainability Reporting, whereby the organization can use e-Bench™ to verify their Greenhouse Gas Emissions abatement program. e-Bench™ through Enviro-Mark Solutions is accredited under the Carbon Disclosure Project which represents over 750 investors with $87 trillion of investment assets.

Asset Centric Structure
e-Bench™ is asset-centric, meaning assets are central to e-Bench™, with data linked to the asset as opposed to the asset linked to the data. This is an important distinction from other systems, which tend to be data-centric, as this provides a framework to sub-divide the organization for analysis and comparison purposes into as many different consuming Entities as may be required. It also allows the separation of areas using common space management procedures and differentiates between landlord or common areas and tenanted or different department spaces similar to NABERS. For a building, it allows space utilization to be benchmarked. For a vehicle or asset, it allows individual performance and efficiency of that asset to be assessed and reported on.

Energy & Utility Management and Invoice Verification
e-Bench™ supports all types of energy and utilities. These include the more obvious ones such as electricity, gas, coal, diesel, gasoline, water and also more obscure ones such as compressed air. e-Bench™ records and monitors all types of energy and utility usage for each chosen entity. It enables invoices for these services to be checked for accuracy and compared with past records on an exceptions basis. This is achieved through an automatic email alert system to advise users of any inaccuracies in their invoices or if consumption patterns are other than what would be expected.

Greenhouse Gas Emission Tracking, CSR and NGER Reports
e-Bench™ provides greenhouse gas emission tracking and reporting in accordance with ISO 14064/1 for Scope 1, 2 and 3 emissions. We also have a MOU with carboNZero, whereby e-Bench™ is able to act as the data collection front end for the CEMARS and carboNZero accreditation certification. As carboNZero is also accredited by the Carbon Disclosure Project as one of only 17 parties able to independently verify emission data as part of their process, e-Bench™ is able to be used for this as well. N.B. CDP is presently being used to report for over 750 investors representing around $87 trillion in investment assets.

e-Bench™ also meets the Australian National Greenhouse and Energy Reporting (NGER) Emission reporting requirements and can also be used as the Corporate Social Responsibility (CSR) reporting system, which in turn underpins sustainable business planning.

In addition to the NGER reports, there are over 200 standard management reports which can be set up to be automatically generated and emailed to the end user. This feature is very powerful in getting others involved in energy management, without it being time consuming.

Continuous Commissioning
Laurence Berkeley Laboratories in California is one of the world’s leading energy management research institutions and they have long stated that continuous commissioning is one of the greatest sources of cost avoidance, with at least ten percent being available per annum.

The question for an organization is how do they know when it is cost effective to re-commission buildings or recreational facilities? We use e-Bench™ to automatically determine that for us. Using the thermodynamic model we can simulate the absolute minimal correlation between degree days and the performance of the fabric. In other words, we know what energy is required to compensate for losses or gains through the external fabric. This figure is entered as the design EUI (kWh/degree day).

The Intervention EUI is then entered. The intervention value is reached by determining what the likely costs of re-commissioning are to be. If say it is $20,000, then this translates into so many kWh and when this divided by degree days is a EUI in kWh/degree day.

If a building being monitored by e-Bench™ records a EUI greater than the intervention point for two-consecutive months an alert is raised, meaning that the user knows it is cost effective to intervene and that the costs of the re-commissioning will be covered by savings.

Benchmarking and Simulation
e-Bench™ was originally designed as a benchmarking database, hence its name. It was subsequently expanded to provide the targeting and monitoring functions we have discussed elsewhere in this proposal. However, it does have at its heart a very powerful benchmarking and simulation modeling tool, which us to normalize for the impacts of climate, utilization, equipment load and construction. The sophistication of these benchmarking features working alongside data capture and tracking systems makes e-Bench™ unique internationally.

e-Bench™ has probably the best benchmarking datasets in Australasia. ETSL who are the developers of e-Bench™ is an energy management company as well. As part of their energy management work they have undertaken a number of Energy Audits, meaning they have acquired a large set of verified energy performance statistics which are used in e-Bench™ as industry standard benchmarking standards.

e-Bench™ also has benchmarking where a series of normalizations or corrections are used. No other package in the world has the same range of sophisticated algorithms and benchmarking tools as e-Bench™.

Simulation is provided using the reverse of the benchmarking normalization engine. Changes in any of the physical characteristics and/or operational hours will provide a savings projection which can then be used as a means of undertaking a cost benefit analysis ahead of implementing any changes.
