Rinnai: Quality is Our Destiny – The Commitment to Manufacturing Excellence

Chris Goggin

Chris Goggin explains how “Kaizen” and “Kanban” methodologies provide insight to the high standards of production values that globally renowned Japanese brands embed into the totality of the manufacturing practices.

Japanese manufacturing is renowned for high levels of aesthetic and operational function. Many of the globe’s leading brands in electrical and combustion technology are from Japan, such as Toyota, Nissan, Honda, and Sony, all of which incorporate the “Kaizen” and “Kanban” methodology into daily operations. 

The term Kaizen has come to mean “continuous improvement,” a broader interpretation can be translated as continuous improvement in personal life, home life, social life and working life. A Kaizen approach focuses on implementing gradual and incremental changes that will produce long-term improvements in efficiency and quality in private and professional life.

To create continuous improvement across multiple platforms in professional and general life, the Kaizen attitude suggests adopting 5 key principles to improve an individual’s approach in work, social life and at home. 

These five principles that facilitate the concept of Kaizen are as follows: Know Your Customer, let it Flow, Go to Gemba, Empower People and Be Transparent. Together, these elements encourage personal and group progression in professional and private life quality output.

 “Know Your Customer” identifies what is truly required by the customer and delivers enhanced end-product that exceeds demand. “Let it Flow” concentrates on creating a smooth flow of processes and practices. Identifying and eliminating production bottlenecks and reducing customer waiting times. This principle focuses on eliminating waste in all aspects of the commercial operation – waste is viewed as any culture or practice that does not benefit the customer or encourage professional productivity. 

The third principle “Go to Gemba” translates as being always concerned with all matters in every department. “Be Transparent” is the idea of utilizing and measuring data that improves company progress. The final principle “Empower People” relates to providing appropriate tools to successfully complete group targets that maximize production efficiency.

Kanban was invented by Toyota engineer Taiichi Ohno during the late 1940s. The term “Kanban” when broken down into two words from Japanese to English means “Kan” (sign)” and “Ban” (board). Kanban is a philosophy that seeks to encourage continuous improvement in production and business methods by measuring project progress through visual Kanban boards. 

A Kanban approach was employed to improve Toyota’s production system by incorporating elements of lean manufacturing into their process. Kanban framework allowed Toyota to transition from a “push” process (products are pushed on to the market) into a “pull” system (products that are created due to market demand). This idea allows companies to risk low inventory levels whilst remaining competitive.

Kanban is also referred to as the “Just in Time” (JIT) system, company production can concentrate on creating products because of consumer demand as opposed to manufacturing products that rely on anticipated demand.

Kanban boards are organised into columns – each column contains visual cards that represent a task during a separate stage of work. The team can easily track task progress and share necessary information that assists in task completion. Kanban boards are an agile and fluid visual form of measuring group progress during the completion of a task.

The creator of the Kanban framework Taiichi Ohno maintains strong links to Rinnai and has had a discernible influence and impact on Rinnai’s production system. Ohno visited Rinnai’s Japanese production plant and provided critical observations and advice that led to Rinnai adopting lean manufacturing principles that enhanced product producing efficiency.

Japanese electrical goods manufacturing is globally recongnised as the highest in performance and production efficiency due to a selection of professional techniques, amongst these are Kaizen and Kanban methodologies. Many Japanese companies adopt elements of both Kaizen and Kanban ideals which has led to Japanese engineered and manufactured products being regarded as being amongst the finest in the world.

3D solid-state batteries: The battle for the skies, the roads, and beyond

Kevin Brundish

By Kevin Brundish, Chief Executive Officer, LionVolt B.V.

Concluding in December last year, the most recent UN climate change conference – or COP 28 – closed with an “agreement that signals the ‘beginning of the end’ of the fossil fuel era by laying the ground for a swift, just and equitable transition, underpinned by deep emissions cuts and scaled-up finance”.

Cynics might raise an eyebrow while voicing the well-worn idiom that they’ll “believe it when they see it”.

Such a reaction is understandable; it feels like we’ve been here before. Many, many times.

But the tide is turning when it comes to battery technology, and it’s turning at the right time: consumer demand for sustainable technologies in travel, healthcare and daily life is surging, and the need for eco-friendly, high-performance batteries has never been more critical.

The shared aspiration of specialists in this sector is to accelerate electrification by addressing the many needs of the market with superior energy density performance batteries. Range anxiety being a good example of why some are nervous to adopt electric vehicles, alongside ease of charging and of course cost. So a cost-competitive and sustainable battery with superior performance is what everybody wants. This must come with no compromise to safety, and must match the life of existing products in use (which will typically outlast the life of a vehicle).

But how do we get there?

Founded in 2020, LionVolt is among the companies that are rising to this challenge. And it all revolves around innovative 3D structured lithium-metal anodes.

Let’s first take a look at how the current lithium-ion technology works and then dive into lithium-metal anodes and the benefits these may bring, what their potential applications are, and what the hurdles are on the pathway to widespread adoption.

Today’s lithium-ion technology

The go-to product in widespread use today is the lithium-ion battery. Given the move to electrification in many industries, including automotive, this technology is being rapidly developed to improve energy density, allowing extended range for vehicles and longer times in between charges for consumer electronics items such as phones and laptops.

A typical lithium-ion battery cell has historically used a lithium based compound in one of the two electrodes (the cathode), and a carbon based material in the other (the anode). To pack even more energy into these cells means changing these materials for more energetic alternatives. 

Over the years, substantial work has been done on the lithium compound – the cathode – whereas the carbon based electrode – the anode – has remained relatively unchanged. But that is changing. 

Newer anodes which introduce materials such as silicon doped carbon compounds, have been developed, but even these are just evolutions of the historical design. A more revolutionary approach is required, which is why the industry is now looking to swap out the carbon material entirely and replace it with a higher performing alternative. Lithium-metal anodes are seen as one of the most promising contenders to achieve exactly this.

Lithium-metal anodes: benefits and applications

The emerging solution now being considered is a new anode material, with pure lithium-metal materials being one of the frontrunners.   

How do they compare to traditional lithium-ion batteries and their carbon-based anodes? Well, it’s hard to do justice to the science in a short article, but it hinges the fact that lithium metal has around 10 times more energy capacity than the original carbon based materials. By utilising this anode material, substantially more energy can be packed into the same volume or material weight, boosting the energy density of the battery cell.

A lithium-metal based anode could be used in a conventional cell as a drop in replacement for the carbon based anode, and give an uplift in energy of around 1.5 times. However, lithium-metal based battery cells face challenges of relatively low charging speed and low life, so there have to be some changes in the cell design to manage this. 

Companies such as LionVolt are working on different methods to tackle these challenges. The approach of LionVolt is to apply a 3D structure on the anode, which is one of the few solutions that overcomes both the challenge of low charging speed and the challenge of low life. This makes a lithium-metal anode a practical reality. And, as a drop in solution that can be made for a similar cost per kwh, we can continue to enjoy the trends of price reduction being seen across the industry. 

What’s more, there’s also considerable potential for the LionVolt approach in next generation solutions such as solid state and sodium (salt) batteries. Solid state offers even higher energy densities and significantly greater safety, but requires a metal anode – such as a LionVolt 3D lithium anode – that can deliver the performance and life for an affordable price.  Sodium-ion cells offer a great alternative to lithium-ion; as sodium is more widely available it is more sustainable, cheaper and has properties which make it safer. However sodium-ion cells are lower in energy density than lithium ion cells, and therefore need the performance benefit of a new anode material such as a sodium anode – a further application of the LionVolt 3D anode approach.  .

But whatever the material used, not only do new anode technologies increase today’s range, they can be ‘dropped into’ the existing supply chain. And, in the case of LionVolt – which is based in Eindhoven in the Netherlands – almost 80 percent of the supply chain needed for the production line can be sourced locally.

So what can these batteries actually be used in?

Well, anything that needs power is a potential candidate for this technology. Initial activity, though, is focused on enabling advancements in electric vehicles (EVs), consumer electronics (including the fast growing consumer wearables segment), and even electric aviation. All share the twin objectives of increasing range or device time and charging more quickly – on top of doing so at less cost to the planet.

In the case of EVs, for example, the greatly increased energy density of these cells means that drivers can travel in excess of 800 km on a single 15-minute charge – this represents approximately four times the ability of traditional batteries.

And it’s only a matter of time before planes get a piece of the action, perhaps first via a hybrid approach that sees engineers unload the propulsion engine or improve efficiencies even further than those available today.

Hurdles

While the next generation of batteries is starting to meet the growing demand for green energy storage in various sectors, full-scale uptake is being hampered by a range of factors, including inertia, ignorance, and the continued dominance of oil and the internal combustion engine.

But the transition to a low-carbon economy is good for governments keen to improve and demonstrate sustainability initiatives. So its acceleration could be facilitated by these same governments, whether through grants, infrastructural investment or tax breaks. Savvy private investors might also see the opportunities that this technology brings to their portfolios. Also taking into account that the replacement potential of next generation batteries is vast. As such, the lithium-ion battery cell market value is forecasted to total USD 400 bn per annum in 2030.

By making such better-performing, more durable and more sustainable batteries for multiple applications, this methodology can tangibly contribute to the clean energy transition – something that readers can be a part of and which the world is watching.

Enabling Great British Energy

As part of Labour’s plan to boost the UK’s renewable energy production, ‘Great British Energy’ will see the production of a greater number of floating offshore wind farms and tidal power projects. However, for these technologies to be a success, it’s essential to have the right enabling mechanisms in place. Here, Mike Torbitt, managing director of resistor manufacturer Cressall, explains the role of resistor technology in making GB Energy a success.

While the exact details about what GB Energy will involve are still uncertain, we can paint a pretty good picture of it from the current information at hand. Starmer’s government intends to invest £8.3 billion of funding into a new, publicly owned green power company as part of wider energy security and sustainability goals.

Delving into GB Energy

GB Energy will work with the private sector to provide investment into emerging energy technologies like green hydrogen, floating offshore windfarms and tidal power. It will also scale investment into existing renewable technologies like onshore wind and solar power.

By boosting the UK’s renewable energy power, GB Energy is projected to create 650,000 new jobs across the UK, lower energy bills, increase energy security and create a zero-carbon energy system to the UK by 2030. Labour has pledged to establish GB Energy within its first few months of parliament by passing a new Energy Independence Act, meaning we could see GB Energy materialise by the end of the year.

While the benefits of transitioning to a 100 per cent zero-carbon energy system are abundantly clear, there are certain logistical and technological considerations to make to eliminate fossil fuels from the energy system completely.

The challenges of renewables

Whether it’s energy from the Sun, sea or wind, renewables have one thing in common — their input energy is extremely variable. For tidal and wind projects, the turbines work in a very similar way, so manufacturers must ensure they can safely manage what can often be high and unpredictable surges of power.

There may be times where winds or waves are so strong that high inrush currents occur. These can result in overvoltages in the system, leading to component damage, or even failure in extreme cases. When renewables like these make up the entire energy system, preventing component failure from scenarios that we know will occur at some point is essential to continuity of supply.

As renewable resources grow in sophistication, it is vital that other systems also keep pace in order to effectively manage the power they create.

Getting in control

Overvoltage issues can be remedied by using resistor technologies, which all work by limiting or regulating the flow of electronic current in a circuit. Depending on the specific renewable application, there are different solutions to prevent overvoltages.

For tidal turbines, a dynamic braking resistor (DBR) can be integrated into the generation and control circuit to protect against any excess power generated by strong currents. Cressall’s EV2 advanced, water-cooled resistor is designed for these applications. The range is modular, so multiple resistors can be combined to handle power outputs up to one Megawatt. The EV2 also boasts an IP56 ingress protection rating, making it able to withstand harsh marine environments and suitable for tidal turbine applications.

In wind turbines, overvoltages are avoided by using a pre-insertion resistor (PIR). Insulated for the full system voltage, PIRs like Cressall’s mitigate against temporary overvoltages, such as those caused by exceptionally strong winds. They also absorb and control transient magnetising currents within transformers throughout the network. This control helps keep voltages consistent with minimal dips, reducing potential disturbances for users of the power network.

While the specifics of GB Energy are still yet to be announced, a fully renewable energy grid is certainly on the cards in the coming years. The industry will need to consider the importance of having the right technology in place to deal with the challenges that renewables bring, and make green energy a viable system nationwide.

Are heat pumps reaching their full potential?

New report by Gemserv and Minviro considers how the strong credentials of heat pumps can be upheld throughout their entire lifecycle by addressing emissions in manufacturing and material sourcing.

Heat pumps are being installed in homes across the country at a remarkable pace, with nearly 5,000 units being installed every month, according to data from MCS. This surge follows the

Government’s £2,500 uplift in funding to help households switch to these low-carbon heating systems.

Heat pumps are widely recognised as a greener alternative to gas boilers, with a gas boiler producing 55% more emissions during use compared to a 10kw heat pump, according to Gemserv. While the transition to heat pumps marks significant progress towards reducing emissions, a critical question remains. Are heat pumps truly living up to their sustainable credentials from production to installation?

A new white paper by Gemserv, a Talan Company’s ESG team and Minviro reveals that there is further potential to enhance the sustainability of heat pumps – specifically within their manufacturing processes. The paper highlights that a current production process of a 10kw heat pump generates 640kg CO2 equivalent in embodied carbon emissions. Key contributors include the use of steel, the choice of refrigerants and tube insulation. While heat pumps are already a highly sustainable solution, focusing on greener manufacturing processes could further reduce their environmental impact which is at risk of being overlooked. It is crucial that there is a rigorous framework in place to limit the knock-on effects from the production process and avoid merely shifting the source of carbon emissions.

By switching to sustainable materials and adopting greener manufacturing processes, heat pump emissions could be reduced by almost half, down to 340kg of CO2 equivalent. This ensures that their strong sustainability credentials are upheld throughout their entire lifecycle, from production to installation.

Key Findings Include:

  • Using sustainable sourced steel powered by renewable energy could reduce carbon emissions by up to 70%
  • Insulation emissions could be cut by 50% by using recycled materials
  • Further reductions can be achieved by transitioning manufacturing operations to renewable energy

The further considerations recommended by Gemserv and Minviro would not only strengthen the environmental benefits of heat pumps but also help manufacturers and installers comply with upcoming regulations. For example, the Ecodesign for Sustainable Products Regulation (ESPR) and the Corporate Sustainability Reporting Directive (CSRD) both push for a circular,

lower-impact economy, with LCAs invaluable in revealing hotspots necessary to achieve compliance. The paper also depicts how LCA insights can enable better-informed corporate sustainability decision-making and improve the bottom line for manufacturers.

The white paper spotlights four key areas for improving the sustainability of heat pumps:

  • The significant role of steel production in driving heat pump emissions
  • The hidden environmental costs of tube insulation in heat pump manufacturing
  • The impact of on-site electricity consumption during manufacturing
  • The need to carefully assess the environmental impact of refrigerants

By implementing these improvements, we can ensure heat pumps, which are already a low carbon heating solution, are made even more sustainable. This will allow households to enjoy

low carbon heating while ensuring minimal environmental impact at every stage of the product’s lifecycle.

Waco Yokoyama, Sustainability and Circular Economy Consultant at Gemserv, commented:

“The life cycle impact of the products we are using to achieve net zero emissions is just as important as the emissions produced by these products in operation. The choices manufacturers and installers make now are critical to ensure an energy transition that extensively reduces carbon emissions and addresses broader impacts on the environment.

It has been an honour to partner with Minviro to explore the alternative materials, production methods and practices that can be implemented to eradicate greenwashing, accelerate decarbonisation and support corporate regulatory compliance for heat pump manufacturers.”

Jordan Lindsay, Research and Development Manager at Minviro, said:

“There is no doubt that low carbon technologies like heat pumps are the right solution to replace fossil fuels. We are proud to have utilised our life cycle assessment (LCA) capabilities in this study to demonstrate how to maximise the sustainability benefits of heat pumps through reducing their embodied carbon in materials and refrigerant choice.

LCA provides a holistic overview of environmental impacts, serving as a reliable evidence base for manufacturers when identifying areas for improvement to prevent corner-cutting and to minimise the risk of creating new environmental or social issues when producing sustainable technologies.”

Microwave Sensors: An Essential Lighting Move

An essential component in any lighting installation, microwave sensors are a key tool in the bid to ensure buildings are run as efficiently and sustainably as possible. In this article, Chris Anderson, Technical Manager at Ansell Lighting explains more about the dynamic technology and how it can help to conserve energy use across buildings of all uses and sizes.

In an era where sustainability is at the forefront of building design and operation, implementing technology that can boost energy efficiency and reduce wastage is a must. One of the most effective tools in achieving this goal when it comes to lighting are motion responsive microwave sensors, an advanced technology that provide effortless control and reduce unnecessary lighting use.

Using a principle known as the ‘Doppler Effect’ to detect movement, microwave sensors emit continuous low-level microwave signals across a designated space or ‘detection area’. These signals reflect off objects and return to the sensor, which constantly analyses the reflections for any changes in the signal pattern caused by movement. When changes are detected, the sensor activates the lighting system, providing illumination as needed.

Ideal for use in both internal and external lighting systems, microwave sensors have revolutionised the way lighting can be operated and managed, ensuring illumination only when there are people actually using a space. The adoption of more flexible and hybrid working practices has seen the popularity of microwave sensors soar, enabling buildings to respond to usage and occupancy patterns with precision.

The main advantage of this is undoubtedly reduced energy use. By ensuring lights are only on when areas are in use, microwave sensors can reduce energy consumption across building portfolios, helping organisations in turn to cut carbon and achieve sustainability targets.

This should also translate to lower energy bills and therefore significant cost savings over time. Additionally, because lighting systems are used more efficiently, there will also be less wear and tear on the infrastructure, leading to reduced maintenance costs and longer lifespans for the lighting fixtures.

Microwave sensors are also much more effective than traditional infrared sensors in environments with walls and glass. Their high sensitivity means movement can still be detected through such obstacles making them the ideal solution for offices with partitioned spaces, warehouses with stacked goods or retail stores with glass displays. They also have a much wider detection range so are an ideal option for large spaces such as car parks, open plan offices, meeting rooms and warehouses.

If microwave sensors are something you are considering installing, then placement, integration and sensitivity must all be taken into account as these factors can have a real impact on the effectiveness of the technology.

Microwave sensors should be installed at a height where they can effectively cover the desired detection area.  Metals, air currents and soundwaves can all cause false triggers so placement near ceiling fans, heating vents, direct sunlight and heavy machinery should be avoided. Microwave sensors should never be installed in metal casings or in close proximity to metal products.

Integration is also a crucial consideration. Ensuring that the microwave sensor is compatible with the existing lighting system and other automation technologies will ensure seamless operation and maximise the effectiveness of the technology.

Finding the right balance in sensitivity of the sensors is also essential if false triggers are to be minimised and the system is to operate reliably. Many microwave sensors will have sensitivity settings which will require fine-tuning once installed to meet the surrounding environment and application requirements. If the sensitivity setting is high, more minor movements will be detected. A high sensitivity will also affect the detection range of the sensor, enabling it to cover a larger area. Higher sensitivity settings are therefore ideal for large, expansive spaces like warehouses, car parks, or open-plan offices.

It is worth noting though that whilst high sensitivity can improve detection, it can also increase the likelihood of false alarms if not properly calibrated. For instance, overly sensitive sensors might react to minor, non-human movements, like curtains fluttering or HVAC systems operating therefore, finding the right balance is crucial.

An ideal solution for those tasked with reducing and monitoring energy use within buildings, microwave sensors are a powerful and adaptable technology. Easy to retrofit or install as part of a newly designed system, they offer a dynamic and functional approach to lighting. They are also extremely useful within a smart lighting system, further enhancing the energy savings that can be made.

Harnessing Renewable Energy for Net Zero and Decarbonisation

Image by Studio-fi
Davide Natuzzi

Davide Natuzzi, Assistant Director Energy, Carbon and Technical, Salix

The UK is facing an energy revolution driven by the need to achieve ambitious net zero targets by 2050. Central to this transformation is renewable energy, which offers cleaner, more sustainable sources of power that help to decarbonise industries and public services alike.

As organisations across the UK seek to reduce their carbon footprints, renewable energy sources provide an efficient solution for reducing emissions and achieving long-term sustainability goals. At Salix, we provide government-supported funding that play a pivotal role in helping public sector organisations transition towards a low-carbon future.

On Monday 23 September, 2024 we launched Phase 4 of the popular Public Sector Decarbonisation Scheme which has focus on decarbonising heat including complementary solutions that support the electrification of heat. By offering financial support also for energy efficiency projects, including renewable energy installations, we are empowering the UK public sector to meet its net zero goals.

We’re working side by side with the public sector to achieve our goals.

The Role of Renewables in the Public Sector Decarbonisation Schemes

Renewable energy is not only essential for reducing the environmental impact of energy production but also for ensuring energy security. With the phasing out of fossil fuels, the UK needs to diversify its energy supply to mitigate the risks of price volatility and geopolitical tensions associated with fossil fuel imports. Renewable energy sources, such as wind, solar, hydropower and nuclear, provide to the UK at a larger scale with a more reliable and sustainable energy supply, which is crucial for the future.

At a smaller scale, the Public Sector Decarbonisation Scheme provides grants for low-carbon heating projects and energy efficiency.

These projects typically include the replacement of outdated fossil-fuel heating systems with low-carbon alternatives, and comprehensive building upgrades to reduce energy consumption.

Although, the decarbonisation of heat is the main focus of the scheme, complementary renewable energy solutions must be included in an eligible project. Projects must also comply with the ‘whole building’ approach criteria of the fund. This inclusion enables the installation of smaller heating systems, supports site energy demand by generating electricity on-site, reduces dependency on the grid, and potentially eliminates the need for costly electrical infrastructure upgrades, all while lowering energy bills.

The Public Sector Decarbonisation Scheme is available for a range of projects that meet the following criteria:

  • ‘Whole building’ approach: Projects should consider the energy performance of the entire building, ensuring that measures taken lead to long-term improvements in energy efficiency and carbon reduction including renewable energy such as solar thermal, solar photovoltaic and wind energy.
  • Energy efficiency: Projects should target energy savings through improved insulation, lighting, or HVAC systems, ensuring that any upgrades align with broader sustainability goals and reduce the capital cost for the low carbon heating solution and reduce the overall energy demand for the site.
  • Low-carbon heating solutions: Buildings must transition to low-carbon heating systems, such as heat pumps or biomass boilers, which provide cleaner alternatives to the existing ‘end of life’ conventional gas or coal and oil heating.

Since its inception, the Public Sector Decarbonisation Scheme has been delivered in phases, with each phase targeting on the specific goal to decarbonise heat in public buildings. The initial phases of the scheme have already demonstrated significant success, funding projects that reduce emissions across schools, hospitals, local authorities, and other public bodies.

For example, during Phase 1, around £1billion was allocated to projects that focus on reducing direct emissions from public buildings. And for Phase 3, around £1.4 billion was allocated to projects that replace end of life fossil fuel heating – continuing to support ambitious energy-saving projects, with an emphasis on incorporating renewable energy sources.

One of the key differences Phase 4 Public Sector Decarbonisation Scheme has to previous schemes, is that the government has changed the way the funding will be allocated. It has moved away from the ‘first come first serve’ system.

The scheme criteria and guidance notes is published on Salix website and the application portal is expected to open in mid-October. We’re asking people to keep an eye on our website to find out more.

And just as in previous phases, renewable energy solutions are included in the eligible technologies. These include solar thermal, small hydropower, solar PV and wind turbine.

Future Opportunities: Community Energy and Beyond

Looking ahead, renewable energy offers exciting opportunities for public sector organisations and communities. Community energy is one such opportunity, where local groups or authorities can take ownership of renewable energy projects, providing clean power to their communities and reinvesting profits in local development.

By facilitating community energy projects, alongside other financial bodies we could help unlock the potential of localised energy generation. This not only supports the decarbonisation agenda but also fosters energy independence and resilience at the community level.

As the UK accelerates its journey toward net zero, renewable energy will be a foundation of the transition. Salix, with our robust funding schemes, is playing a vital role in ensuring that the public sector can lead the way in decarbonisation and energy efficiency. By supporting the installation of renewable energy systems, improving building efficiency, and promoting low-carbon heating solutions, together with government we are enabling the UK to meet its ambitious climate goals. With future opportunities like community energy on the horizon, the path to a cleaner, greener future is more achievable than ever.

Smarter for business

Adrian Barber from Prefect Controls investigates the broader benefits of smart buildings on business performance.

The evolution of smart buildings sees the integration of IoT devices sensing, monitoring and controlling environmental conditions. The internet enables Information exchange with other devices. Intermediate interfaces present, interpret, and analyse data. This helps us to understand performance for many aspects including access, use, heating, and safety, to name a few.

Student accommodation is an unusual type of commercial residence, compared with other multi-occupancy property, such as residential flats or hotels. For example, occupancy patterns are different. Hotels rooms are frequently visited by house-keeping teams who monitor their condition, while occupiers of residential flats have a vested interest, in the case of heating, to manage their environment, balancing comfort with economy.

For managers of student rooms, their estate is dense, there is a lack of visibility. Without regular access to rooms, assessing conditions is impossible. It may appear that the building is performing effectively, but just because there are no complaints, doesn’t mean there aren’t any issues!

Student accommodation is a prime example of smart technology delivering many benefits. One advantage – managing and reducing energy consumption. Energy teams can see what is being used where and when and create efficiency strategies. But smart technology is not all about energy, carbon, and sustainability.

The promise of central collation and interpretation of quantitative and/or qualitative data helps to build strong business cases to install equipment that makes buildings perform more effectively. Broadening the scope of a smart system and providing multi-faceted data should encourage buy-in from other parties – Health and Safety, Maintenance, Welfare, Operations, etc. not to mention investors.

In practical quantitative terms, value is straightforward to identify. Indisputable, robust figures prove energy and water consumption. The measuring of which unveils space and water heating data. Adjustments made to temperatures and timings, will feed savings straight onto the bottom line.

Analysis that has the intention of making savings, doesn’t have to conclude that energy use should be restricted though. Better information will help to identify waste. If waste is targeted, the quest to make savings by restricting energy use is diminished, therefore, there should be no detrimental effect on the comfort of residents. Evidence from smart control has proven that heating load can be reduced by 50% per room simply by cutting waste.

More indeterminate, but equally of value, is smart technology’s qualitative data that through monitoring and control, delivers time and financial efficiencies, but also wellbeing benefits.

On a catastrophic scale, imagine a kitchen fire, caused by an unwatched pan or, undetected escape of water – each potentially causing millions of pounds of damage. Use of smart tech would limit/prevent such occurrences. Insurance companies are increasingly interested in proactively reducing risk with such applications.

Less dramatically, temperature data collected from water pipes saves on labour cost, eliminating the need to visit every tap to flush the system. Simultaneously, evidence is logged, proving Legionella water safety plan criteria is met.

Occupancy data helps with maintenance scheduling. Knowing when rooms are empty, means work can be carried out efficiently and conveniently.

Humidity data identifies room conditions that could promote damp and the growth of mould. Quick action will prevent the worsening of the situation.

Tighter water temperature control obviously has a financial benefit, but monitoring also can present alerts of overheating and the potential for scolding.

Smart building systems provide access to better information and encourage more efficient management practices. ESG strategies also benefit. Businesses that can prove their environmental impact, social awareness and ethical behaviour credentials are more attractive and improve their reputation with employees, customers, supply chain, and of course investors.

Smart organisations invest in smart buildings.
