R8 Diagnostics turns undetected faults and anomalies into tasks!

R8 Diagnostics can be used independently from the R8 Digital Operator full service. According to different statistics every third HVAC component is underperforming due to unused data, human errors and technical faults in buildings.

R8 Diagnostics is a data driven automated analytics to detect HVAC systems faults and anomalies that are invisible to automation systems or technical teams. Ticketing and data driven validation is a natural part of R8tech Diagnostics. Also, a 20% reduction of maintenance and renewal cost over the HVAC systems life cycle of 20 years is estimated due to R8 Diagnostics.

R8 Diagnostics automatically detects faults, anomalies and analyses the systems technical performance based on historical operation. It is essentially a tool that simplifies and improves the efficiency of building’s technical management.

R8 Diagnostics module consists of algorithms that examine in detail all HVAC equipment and meters data that is collected from the Building Management System (BMS; room’s indoor climate sensors and devices, ventilation units, heating and cooling plants).

Compared to alerts present in the current BMS, R8tech approach is a more advanced system, diving into the statistical performance of every single component. To work with solely BMS faults is insufficient and inefficient.

R8 Diagnostics is a multi-tiered approach that is a combination of a rules-based, relational hierarchical model and statistical analysis of the system’s historical performance.

Some of the faults can be detected only seasonally due to seasonal temperature fluctuations. Additionally, stress tests are used to test out the components’ reaction to the set point change.

One month after the R8 platform’s integration with Your building’s BMS, an initial diagnostic report is submitted and presented to You.

What is Initial Diagnostics Report?

It provides an overview of the building’s room temperatures, automation, heating, cooling, ventilation, condition of the air conditioning systems and a list of improvements that would enable further savings, more advanced fault detection and better energy consumption overview and anomalies detection.

The report also includes a statistical overview of key parameters in rooms and equipment (min, max, average temperatures, percentage of time in cooling mode, percentage of time in heating mode). Please see attached appendices General Overview of Faults Detected by Diagnostics Module and Building Statistical Overview.

What will happen with the discovered faults?

The faults detected by the Diagnostics are submitted automatically as Tasks to the technician(s) with relevant competence appointed by You. It is the technical team’s responsibility to solve the discovered issues in mission-critical time frame.

What is Tasking?

Tasking is essentially a tool for the technical team to increase their work performance. The technical team is connected as users with any platform and as a fault is detected by the algorithms, it is directly assigned to the technical person responsible.

Tasks can be made automatically or manually, and a person responsible can be selected. An automatically found fault from the Diagnostics module contains analyzed information that describes the reason why the fault was generated.

Once the building is integrated completely, every HVAC component has a location and contains technical and historical operational information.

Once a high priority task is generated, an email is sent to the person responsible to call for urgent action. It is the technical team’s responsibility to solve the discovered issues in mission-critical time frame.
