Servitisation, smart systems and connectivity of instrumentation
There are many buzzwords associated with the multitude of new developments in today’s technological world, and the use of terms like Smart Instrumentation, The Internet of Things (IoT), Big Data, and Servitisation are becoming increasingly common. Whilst we may think that we are familiar with these descriptors there is sometimes a disconnect with what they mean to the industries where they apply.
BSRIA is uniquely placed to be at the forefront of the use and application of technological innovation especially within the building services industry. BSRIA’s vision is to be leaders for information, knowledge and improvement for the built environment; with an aim of ‘making buildings better’, so concepts such as the BSRIA Business-Focused Maintenance (BFM) methodology fit this remit and have become increasingly relevant as technology has advanced.
Today’s engineers can now use a wide variety of instrumentation that can be considered ‘smart’. However not all smart instruments are created equal and to be truly smart the monitoring data must be connected to the Internet of Things (IoT), generating data that is uploaded and analysed either by a human operative or a software application. This can be used in preventative maintenance planning, helping to move away from planned scheduled maintenance schedules which are often expensive and unreliable in identifying faults and potential failures. Some of the most widely used monitoring methods include ultrasonic flow meters, temperature monitors, humidity monitors, power meters and process emissions analysers. These instruments and others are indispensable tools for engineers, they provide a non-invasive, user-friendly and cost-effective solution to maintenance testing which can be used as part of a smart system of monitoring.
|A smart IoT instrument must be linked to the internet through a hub or router. The continuing development of smart technology and the IoT in the instrumentation sector means that something called servitisation is becoming increasingly relevant in the way that today’s building services sector customer offerings are created and marketed.|
The concept of servitisation was first discussed by Vandermerwe & Rada in their 1988 paper; ‘Servitisation of business: Adding value by adding services’, published in the European Management Journal. The Servitisation of products involves a strategy of adding value by adding services to products or even replacing a product with a service package. For example, supplying an HVAC system and adding various levels of service, additional features and product support. Customers can be offered a choice of options for a product ranging from supply of the basic physical parts of the system, right up to a complete turnkey solution including all support, monitoring, maintenance and repair. For instrumentation the basic physical unit can be supplied, with additional services including accessories, software, service & calibration and data management being sold as additional options. Data management services are a relatively recent addition to the instrumentation sector, this can include mobile apps, data portals, warehousing & storage and data processing.
The way that servitisation is offered to a customer can be business or even product specific, for example there could be an initial capital expense payment, or the entire cost could be fully included in a subscription or lease type agreement. This helps the customer to manage capital expenditure and the seller to manage their finances by making income streams more consistent and aiding cash flow management. However, it is important to supply products that add value to the performance or create cost savings for a customer, over-specification or ‘over-servitisation’ of smart systems can be pointless, expensive and can lead to loss of customer goodwill.
With the user-friendliness and wealth of applications for smart instruments, you don’t need to be an expert, employ a consultant or have large budgets to get the data you need. We work closely but independently with a wide range of equipment suppliers which means we can provide solutions to meet our customer’s specific needs. We can supply a wide range of smart instruments from entry level units up to state-of-the-art professional cameras and all at an affordable price.
We recognise our client’s needs are time critical and we have equipment available for hire and sale direct from stock or with short lead times. In processes where plant failure can cause down-time that can potentially cost millions of pounds in lost income it is imperative that critical building services must never be disrupted by failure. We pride ourselves on providing fit-for-purpose, user friendly and cost-effective equipment.
At a basic level, an IoT instrument takes a measurement, this data is uploaded to a processing system, the data is analysed and any potential risks or failures are highlighted – this can result in an automated system response (e.g. process change or shut down) and/or an alert to an engineer (email, text, etc.) to highlight the issue for action (e.g. schedule specific maintenance or equipment replacement). The data analysis process is key to effective system operation, it can use Big Data processes to highlight potential problems (i.e. using software to analyse very high volumes of data to identify patterns consistent with potential problems). Artificial Intelligence (AI) software is one of the most recent developments in building control and monitoring technology and is an ideal fit for smart systems, it has the potential to deal with huge volumes of data and identify problems more effectively than human or traditional digital algorithm analysis. AI is a relatively new field and advances in this area are likely to increase at pace over the coming years and impact all aspects of the sector.
The development of smart IoT instrument systems is also driving servitisation by moving the point of value from physical instruments towards the software and data handling. There are many ways in which the building services sector has opportunities to use big data to create value for the customer, including improved information security and enhance physical comfort to increase worker performance. These trends are discussed in detail in the BSRIA publication BG75/2018 Building Services Analytics.
IoT instruments can also be linked to or part of a Building Management System (BMS) and it also fits with the BSRIA Business-Focused Maintenance (BFM) methodology first published in 2004 and updated in 2016 (BFM Guide BG53/2016). BFM plant maintenance requirements can utilise smart instrumentational monitoring and data processing. An aim of BFM is to provide engineers with a methodology for utilising maintenance budgets more effectively, this aligns with the design of smart instrumentation systems and the creation of service offerings. Assets critical to the business are maintained, while other less critical assets are managed as well as possible within the available budget. By assessing and prioritising plant maintenance needs for risks and criticality to the business, engineers and managers can ensure their maintenance effort is resource efficient, focused, cost-effective and increase their resilience to engineering risk.
The way that BMS data is managed and processed is as important as the instrumentation itself, it must be generated and analysed in a format that can be used to create plans and actions that add value, generate efficiencies and create cost savings for the customer. Some of the first digital breakthroughs have been in predictive asset maintenance and real-time monitoring. Digital twin systems where a virtual model of a physical asset is created allow predictive analysis to be performed and can highlight potential failure points more effectively than routine planned monitoring work. However, focus must always be on the key aim of smart systems to simplify processes for the end user, systems should work for the user not the other way around, this applies to the instruments, their control systems and product support.
BSRIA Instrument Solutions is ideally placed to provide its customers with the latest developments in smart instrumentation as it supplies product from a comprehensive range of leading suppliers.
