Building Intelligence with Submetering Solutions

Do you need a qualified and knowledgeable company that can offer you state of the art technology to manage your energy consumption use for your home, business or corporate buildings?

e2Networx (Pty) Ltd is a company headquartered in South Africa whose prime business is the design, supply and management of all points of energy consumption for all buildings that require the recently announced Energy Performance Certificate (EPC) We supply best of breed technology solutions that have been tried and tested in the harshest conditions that most of us endure on a daily basis with the current energy crisis. Our vast field of highly skilled engineers understand what is required in order to offer you a sound and reliable energy base in order to maximize your electrical or power savings. This technology is AI driven and learns your power usage which it is then is able to interpret to help you manage your energy consumption. 

We cut out the complexity of measuring and validating the  consumption of electricity, water or gas, from any metering point or device, at any or many locations, at any time interval. Our data is synced in real time with the local Municipal or Eskom rates for the specific area and is formatted in easy to read text as well as in graphic format for historical reference and trend lines.  We distribute accurate utility bills and simple supporting utility usage information that makes it quick and easy for tenants and residents to reconcile and settle promptly. Our effective and efficient utility recovery service collects all your utility dues, free from the resource-sapping queries, reconciliations and the time-consuming interactions with bulk or municipal suppliers that bog your people down and drive your opportunity costs up.

Portfolio managers struggle to get accurate and timely utility meter data in one format. e2networx can integrate all of a property’s main utility meters onto one real-time data collection system which provides analytics, automated reports and alarms through e2Meter™. This enables portfolio managers to effectively manage their utility costs, energy efficiency programs, GHG emissions, and corporate sustainability reporting. 

Portfolio and building level managers can use this data to:

  • monitor their utility costs/allocation
  • verify utility bills
  • benchmark properties against each other
  • track effectiveness of energy retrofits
  • complete portfolio reports for Energy Star, RealPac, GRESB, etc;
  • do real-time monitoring and alarming for energy efficiency and anomaly detection
  • Building Level Metering/Portfolio Metering
    The most important meter points of any property are the main electricity, water, gas and district energy utility feeds. Managing these meter points allows understanding of when and where the property is using utilities and is the start of
    building level energy management. This can also serve as a check on utility bills and be used for forecasting energy costs.
    e2networx has several solutions for utilizing these main meters to enable the property and the portfolio to improve their energy management, accounting and sustainability reporting. 
    These include:
  • Direct integration with the main utility meters using data loggers, either via pulse, Modbus, or other communications protocols available on the utility meter(s)
  • Supplying and installing check meters downstream of the main utility meters
  • Back-end integration with utility database. This is dependent on the utility’s capabilities and regulations and/

or the availability of open-integration platforms, such as Green Button 

  • Utility Billing Data collection and reporting (does not allow for interval data and energy profiling)

Here is a summary of the benefits of deploying building level
metering for your portfolio:

  • Know when and where your building is consuming energy and water as part of a monitoring and targeting program Immediately identify abnormal consumption, as opposed to waiting weeks or months for utility bills to show the problem
  • Validate consumption on your utility bills 
  • Benchmark all properties’ energy use intensity and target energy conservation efforts accordingly
  • Collect all utility interval data in one place for easy sustainability reporting and submissions

Below is the process we follow to ensure a professional approach in obtaining your EPC Compliance certificate

Step 1: Consultation

The idea of starting the process off with a consultation is to ensure that all parties understand their roles and responsibilities from the outset. The consultation will be chaired by one of our designated EPC specialists who will explain the entire process to your building representatives. After this consultation, all parties should have a good idea of what is needed from them before the actual EPC inspection activities (which are needed in order to issue the Energy Performance Certificate) commence. This should also give all parties a good indication of how long the process is expected to take and what the related costs will be.

A major part of this consultation is data request. The first inspection activity that forms part of our EPC process is the analysis of the relevant data, being data relating to the size, occupancy class and energy consumption of your building. We have a checklist of data that we will request from you. Upon receipt of this data, we will be able to advise on steps that need to be taken to simplify the process. The quality of data that you are able to provide plays a major role in the complexity of the process.

Step 2: Feedback on Data Analysis

Once we have had a chance to look at your data we will be well-positioned to advise you on how we will be moving forward with the EPC process. This can go one of two ways. If the data that you provide is extensive enough for the purposes of your building, then our Inspection Team can start with further analysis and verification of the information that you have provided.

Once all of the information that you have provided can be verified by means of our internal verification checklist, the team will get started on compiling an EPC report for you. If, however, the data provided to us is insufficient for purposes of a SANS 1544 Energy Performance Certificate, we will need to do something about that. Fortunately for you, Powerstar has been at the forefront of innovative energy solutions for the better part of a decade. We are thus well geared to help you gather all of the relevant data that will allow us to issue you with an accurate Energy Performance Certificate.

In most cases, it will be possible to ascertain whether the data that you have will be sufficient at the Consultation stage. If this is the case, we will inform you of this as soon as possible so that we can make the necessary changes at an early stage to stop costs from piling up.

Step 3: The Inspection

We are required to inspect your building to verify that all of the information that you have provided us is accurate. Once our team is happy with the quality of data that you have provided us, we will contact you to arrange for one of our Inspectors to conduct an on-site inspection of your building. The duration and complexity of this inspection will depend on various factors such as the size of your building, the number of occupancy classes, the energy used outside your building, and the different types of energy carriers that supply your building with energy.

Step 4: Report Compilation

SANS 1544 requires the energy performance data of your building to be displayed in a specific way. The purpose of our EPC Report is to lay all of this data out for you in a way that makes sense to you as building owner. After all, the purpose of this exercise is not only to comply with the law, but to turn such compliance into an opportunity for your building to improve on the way it uses energy.

The report highlights the calculations that we performed along the way to get to your final Energy Performance Scale rating. This enables you to better understand where the deficiencies are in your building and how you can improve before your next Energy Performance inspection in 5 years time.

Step 5: Issuing your Energy Performance Certificate

Once we have completed your EPC report, all that is left to do is for us to issue you with an Energy Performance Certificate. This is the certificate that you are required by law to publicly display at the entrance of your building. The regulations governing these certificates provide that you (the building owner) are responsible for communicating the result of our inspection and the corresponding certificate to the South African National Energy Development Institute. However, since we promised to help you till the end, we will take care of this to make sure that all of your compliance obligations are fulfilled.
