it all goes away isn’t a strategy. Businesses that refuse to engage with AI risk being left behind, while those that take the time to understand it, set ethical boundaries, and integrate it thoughtfully will be the ones that thrive. Are you keeping up? You’ll find a great example of this thinking in our Lighting section this month, where Daniel Hammond from the BHA School of Lighting shares ways to use AI to enhance the creative process without losing the human element that makes their work meaningful (page 16). Beyond AI, this edition also includes a key focus on Tools & Tooling.

And there’s plenty more in our regular Lighting feature too: on page 14, see what happened Smart geyser cuts water heating costs by up to 85% W ith electricity tariffs set to rise again in 2026, households and businesses are under increasing pressure to cut energy costs. The innovative integrated heat pump (IHP) geyser from Power4Less offers a breakthrough solution, reducing water‑heating expenses by up to 85% while delivering reliable, eco‑friendly performance. Unlike conventional geysers that rely on electricity-hungry elements, the IHP geyser harnesses natural heat from the surrounding air. A fan draws air into the system, where heat is absorbed, compressed, and transferred directly into the water. This cycle repeats continuously, consuming less than half a kilowatt of power – less than a kettle – and cutting energy usage by up to 85% when compared to traditional geysers. The numbers speak for themselves: A 200 L electric geyser uses a 4 kW electric element to heat water to 55 °C. The average cost of electricity is R3.91 per kWh (2025 prices). Let’s assume this geyser is used once in the morning and once in the evening for two showers. This equates to an electricity spend of around R78.20 per day or R2,377 per month over 30.4 days. In comparison: The IHP geyser uses 0.5 kW to heat water to 60 °C on both the 200 L and 300 L models. This is up to 85% less power usage. We’ll keep electricity costs at R3.91 per kWh and the same morning and evening usage for two showers. This equates to an electricity spend of just R7.04 per day or R214 per month over 30.4 days. This is a saving of R2,163 every month and annual savings of up to R26,000! Savings are also compounded as tariffs continue to rise. The IHP geyser integrates seamlessly with smart app controls and a colour touchscreen keypad, allowing users to adjust water temperature or power down remotely during holidays or off-peak business periods. To prevent those “geyser bursting at 3am” fiascos, the IHP geyser is crafted
going to save the world or destroy it. The truth, as usual, lies somewhere in the middle. Let’s be honest: AI is here to stay. It’s not a passing trend or a gimmick. It’s a tool, and like any tool, its value depends entirely on how you use it. Used responsibly and ethically, it can help businesses streamline processes, improve decision-making, and free up time for the work that truly requires a human touch. Used carelessly, without thought or oversight, it can cause real problems. The keyword here is “responsibly”. There’s a lot of fearmongering out there suggesting that AI is coming for our jobs. But let me put it this way: when the calculator came along, people worried it would replace the need for anyone who could do maths. It didn’t. It just made the process faster and freed people up to focus on more complex problem-solving. AI is much the same. It’s not here to replace you. It’s here to support you.

Water mist fire suppression for high-value assets W ater mist fire suppression minimises water damage, supports life safety, and offers strong environmental performance, particularly in specialised and high-risk applications. “Clients increasingly want fire protection that is both technically robust and in turn reduces collateral water damage, clean-up time, and business interruption. Applications vary, and include data centres, control rooms, and IT facilities. Fine droplets cool hot surfaces, inhibit fire spread, and limit damage to equipment. Although water mist is not intended to
for a specified period within a sealed volume. In highly ventilated genset rooms or plant areas, this can be impractical. Water mist can offer a more robust solution in such environments, as it does not rely on enclosure tightness in the same way. Limitations and the importance of proper application Despite its advantages, water mist is not a one-size-fits-all answer. Industry guidance stresses that there are scenarios where other technologies remain preferable. Large, open or very tall spaces with strong air movement may dilute the mist and reduce effectiveness. Certain flammable liquid and gas hazards, or very rapid-growth fires in open process areas, may be better addressed by foam, dry chemical, or gas systems, depending on the risk assessment. Where very deep-seated fires in bulk solids are possible, traditional sprinklers or specialised systems might offer better penetration. New developments and emerging applications Research and innovation in water mist fire suppression have accelerated in recent years, both internationally and in markets relevant to South Africa. One key area is new-energy and battery-related risks. Recent reviews highlight the potential of water mist – alone or in combination with gaseous agents – to manage lithium-ion battery fires, or those from solar installations, wind turbines, and/ or biomass systems, thanks to strong cooling performance and reduced environmental impact.
penetrate sealed cabinets, it is effective at stopping fires from spreading beyond the point of origin, and reinstatement is often quicker than after a conventional sprinkler discharge. Advantages of water mist systems A key benefit is reduced water consumption and water damage. Since the droplets are so fine and are used more efficiently, water mist systems typically operate at significantly lower flow rates than sprinklers. This reduces the volume of water that ends up on equipment, finishes, and sensitive contents, and can ease demands on water storage and pumping infrastructure. The second is enhanced life safety and tenability. By absorbing heat and limiting smoke production, water mist can extend the available safe egress time, improve visibility, and reduce the risk of flashover and backdraft in certain scenarios. The third is environmental performance. Unlike halon and many legacy chemical agents, water mist relies on water as the primary extinguishing medium and therefore has no ozone depletion potential or long- term global warming impact from the agent itself. The fourth is resilience in ventilated or ‘leaky’ spaces. Gaseous systems depend on maintaining a minimum agent concentration
sensitive to their operations,” says ASP Fire CEO Michael van Niekerk. “Water mist systems give us another proven tool in the engineering toolbox, especially where conventional sprinklers, foam, or gas systems present unacceptable trade-offs in terms of water damage, downtime, or enclosure integrity.” What is water mist fire suppression? Water mist systems are water-based fire suppression systems that discharge very fine water droplets through specially engineered nozzles at low, intermediate, or high pressures. According to NFPA 750, the Standard on Water Mist Fire Protection Systems, water mist is defined as a spray in which 99% of the water volume is in droplets smaller than 1,000 microns in diameter at the minimum operating pressure. By comparison, conventional sprinkler droplets are significantly larger. The much smaller droplet size dramatically increases the total surface area of water exposed to heat. As the droplets absorb heat and rapidly evaporate to steam, the system cools the flames and hot gases, displaces oxygen immediately around the fire, and reduces radiant heat transfer. The result is fast fire control or extinguishment, with a fraction of the water flow of traditional sprinkler systems, which
Michael van Niekerk of ASP Fire.
Water mist fire suppression has matured from a niche technology into a mainstream option for a wide variety of specialised applications. Its ability to deliver fast, effective suppression, with reduced water usage and limited collateral damage, makes it particularly attractive for critical infrastructure, heritage, and high-value industrial environments across Africa. “Every project starts with understanding the risk,” concludes van Niekerk. “Water mist systems are not a silver bullet, but in the right context, they offer exceptional performance. When we integrate them into a rational fire-safety design, backed by proper standards, testing, and maintenance, they help our clients protect people, assets, and productivity in a world of increasing fire risk.”

Is the national minimum wage hike a lifeline for workers or a risk to jobs?
By: Donne Nieman, sales director at Workforce Staffing F rom 1 March 2026, South Africa’s national minimum wage will increase to R30.23 an hour, a 5% rise that takes the rate past the R30 mark for the first time. For millions of low-paid workers, the increase offers modest relief against
The risk is not sudden, large-scale job losses but a gradual change in how companies manage their workforce. Over time, this could mean fewer entry-level opportunities for workers trying to enter the formal job market. - Donne Niemand, Workforce Staffing
rising living costs. But in an economy with stubbornly high unemployment and weak growth, the adjustment also raises an important question: how do we protect vulnerable workers without putting further pressure on job creation? The answer lies in understanding the delicate balance between improving livelihoods and sustaining employment in a fragile labour market. In the bigger picture, the increase is significant. While the adjustment is modest, it forms part of a series of annual increases aimed at keeping wages in line with inflation and rising household costs. Will it close the gap between earnings and the true cost of living? Probably not. But the intention is clear: to stop the lowest-paid workers from losing ground. The pressure on employers is real Higher wages also have an impact on how businesses operate. For labour-intensive companies working with tight margins, rising wage costs are a major expense. This doesn’t mean employers are against fair pay, but in a weak economy, every increase in costs means tough decisions. Businesses need to stay competitive,
Donne Nieman of Workforce Staffing.
especially those that compete in global markets. To manage higher labour costs, some may invest more in automation, mechanisation, or new technology. Others may slow down hiring, restructure their operations or reduce their reliance on lower-skilled roles. The risk is not sudden, large-scale job losses but a gradual change in how companies manage their workforce. Over time, this could mean fewer entry-level opportunities for workers trying to enter the formal job market. South Africa’s competitiveness challenge South Africa faces a difficult reality. The country has many people looking for work, many of whom are low-skilled. In the past, the availability of affordable labour had been one of the factors that attracted investment. As labour costs increase, this advantage
becomes less certain. If higher wages are not supported by improvements in productivity, skills, and economic growth, businesses may become more cautious about expanding or investing. This is why minimum wage increases cannot be considered in isolation. Protecting workers is important, but lasting wage growth is only possible if the economy becomes stronger and businesses remain competitive. Businesses are planning ahead One important shift since the introduction of the national minimum wage is predictability. Employers now expect an adjustment each year from 1 March and build this into their budgeting cycles. While the exact percentage may vary, the increase itself is no longer a surprise. As wage costs rise, workforce flexibility is becoming an essential strategy. Many businesses experience fluctuating demand,
with periods of peak activity followed by quieter cycles. Maintaining a full-time workforce through these changes can be difficult, particularly as labour costs increase each year. Flexible staffing approaches, including the use of Temporary Employment Service (TES) providers, allow employers to scale their workforce in line with operational needs. For workers, this model can also offer an important benefit. By being deployed across multiple client sites as demand shifts, employees can maintain more consistent employment and income rather than facing intermittent layoffs or reduced hours. In a constrained labour market, this type of shared flexibility can support business sustainability while helping workers maintain greater income stability.

Safehouse: non-compliant electrical products put consumers at risk S outh Africa has no reliable national statistics on electrical product compliance, with independent industry
protect consumers by carefully verifying test reports and Letters of Authority (LOAs) before listing products. “Retailers need to understand exactly what they are selling, and act as the first line of defence against unsafe or non-compliant goods,” Jonker says. “Too often, retailers rely blindly on documentation that should be rigorously scrutinised, particularly when prices seem too good to be true.” As a result, Safehouse is urging both consumers and retailers to learn more about its mission to remove nefarious suppliers of unsafe electrical products and services and to eradicate dangerous products from the market. They also want to make electrical safety information understandable and accessible. While many compliant products are still updating their packaging, consumers can start identifying trusted items by the Safehouse mark on electrical appliances and other products. Consumers can also visit the Safehouse website to see which companies have committed to producing compliant products and protecting lives and livelihoods across South Africa. Safehouse, which operates on a peer- review model with members funding laboratory testing and committing to a strict code of conduct, has become the go-to platform to support ethical compliance, conduct credible independent testing, and encourage higher standards across the sector. The association wants to partner with authorities, not replace them, by providing technical insight and evidence-based recommendations. “You can’t see electrical safety with the naked eye. Two products may look identical on a shelf, yet one can meet every requirement while the other fails critical safety tests. That’s why ongoing compliance testing matters, and why consumers and retailers need a way to know who is doing things properly,” says Jonker. “This is a sector where safety should never be optional. A more informed marketplace, from sales floors to boardrooms, will drive demand for compliant products and improve national safety standards,” he concludes.
members,” says Safehouse’s technical lead and chairperson, Connie Jonker. According to the South African civil society organisation, Tax Justice South Africa, the influx of cheap, non-compliant electrical products into South Africa, many entering through porous borders or online channels, poses serious risks to consumer safety and local industry, with surveys showing that nearly 80% of electro-technical companies are highly concerned about this growing problem. Jonker says that no one can determine compliance through visual inspection alone. He says that tests, which can cost several thousand rand each, involve the assessment of dimensions, flammability of materials, insulation, and tripping currents of circuit breakers. These can only be conducted in proper laboratories. “Even experienced people cannot reliably identify a compliant product on a shelf.” Jonker, part of Safehouse’s management team, who brings over 50 years of electrical industry experience to the organisation, says that the compliance situation in South Africa is a disaster. “A lot of non-compliant products are entering the country without proper control. We can only advise; we cannot force products off shelves. We send test results to companies and urge them to fix issues, and if not, we report to the NRCS. But not much happens after that. It is also virtually impossible to track what action, if any, the NRCS takes on any compliance issues raised,” he says. “Different products carry different risks. If a circuit breaker doesn’t trip when needed, you could have a fire or an electrical shock. Other issues, such as incorrect marking, may not be immediately dangerous but can lead to products being used incorrectly,” says Jonker. Buying very cheap products increases the risk of serious non-compliance, and the consumer must be aware that buying cheap products poses its own risks, even when done by a third party and signed off via Certificate of Compliance (CoC). The accountability for the safety of electrical products being sold in South Africa also lies with the retailers, who Safehouse says have a fundamental responsibility to
and unscrupulous local manufacturers to sell a wide range of products under a single approval certificate. Compounding the problem is the NRCS’s refusal to publicly disclose non-compliant products, a practice that leaves all consumers exposed to unnecessary risk. The recent South Africa Illicit Economy 2.0 Report, launched by the Transnational Alliance to Combat Illicit Trade (TRACIT) in conjunction with Business Unity South Africa (Busa), states that South Africa’s illicit trade is estimated at R100 billion, or about 1.5% of GDP. This figure barely captures the wider damage it inflicts on lawful manufacturers, retailers, employees, and tax revenue. And while the NRCS is making some effort to control non- compliant and illicit products across sectors, including building materials, automotive components, chemicals, and electrical products, its overall enforcement reaches less than 0.5% of South Africa’s illicit trade. “Robust processes are being put in place thanks to our members’ continued commitment to product safety and regulatory compliance. Consumers can now make more informed and reliable choices by selecting products bearing the Safehouse mark and checking the Safehouse website to verify suppliers and businesses that are accredited
testing consistently showing high failure rates, says the voluntary electrical safety association Safehouse. Most South Africans trust that if a product is being sold in a store, it must be safe because it is assumed that the retailer has vetted the product. Unfortunately, that isn’t always true. Many products available on the shelves fail to meet basic safety requirements. And while non-compliant electrical products are not always immediately dangerous or seen up front as dangerous, they can pose significant risks. More concerning is the systemic threat of South Africa’s illicit electrical goods trade and the far-reaching consequences it has on consumer safety, economic stability, and industrial sustainability. Safehouse was founded in 2014 in response to ineffective regulation and the lack of robust market oversight under the National Regulator for Compulsory Specifications (NRCS), which relies primarily on administrative approvals and single type- test reports. Without ongoing quality control, the risk of undetected non-compliance increases significantly, creating a system that can be exploited by certain importers

This approach turns scarcity into strategic The solution: systemic CBM AI-driven CBM offers a rounded and proactive solution. For example, by embedding sensors to collect real-time data on temperature, vibration, pressure, and wear, CBM continuously monitors equipment health. Predictive analytics then identify issues before they escalate, enabling interventions only when necessary. This approach reduces downtime, minimises human error, and extends asset lifespans. Over time, CBM systems self-optimise by learning from new data points, creating a cycle of continuous improvement. Importantly, human judgment remains vital to complement AI insights, ensuring multi-layered decisions in complex environments. CBM offers measurable benefits such as: • Efficiency and uptime: predictive analytics reduce costs and downtime by 20%, according to the International Energy Agency. • Resource optimisation: according to a recent Schneider Electric report, early CBM implementation can result in up to a 40% reduction in on-site maintenance interventions and a 20% decrease in operational costs. • Sustainability: CBM reduces energy waste and extends equipment lifespans, thereby directly supporting carbon-

Unlike global superpowers that invest heavily in sheer computing capacity, South Africa doesn’t need to be the largest computing market to lead in innovation. What matters today is how we apply computing to accelerate insight, discovery, and socio- economic progress. That’s where AI-accelerated simulation, combining high-performance computing (HPC) with machine intelligence, comes in. Instead of waiting hours or days for results, we can simulate complex scenarios in seconds, enabling faster decisions and innovation than traditional methods.

According to Future Market Insights, the global HPC market is projected to be worth around $60.2 billion in 2025 and to continue robust growth through the next decade, underscoring explosive demand for advanced computing in science, engineering, and AI workflows. Across industries, the AI-enhanced HPC market is also expanding quickly, driven by the need to simulate ever more complex data and models at speed. Yet, in many emerging economies, including South Africa, raw computing power alone is rarely sufficient. What holds greater strategic value is a simulation that turns limited infrastructure into accelerated insight. South Africa’s digital transformation is measurable South Africa remains one of the most digitally active economies on the continent. in infrastructure to meet AI’s growing demands; on the other hand, it still (often) relies on outdated maintenance methods to manage mission-critical equipment. But with rising energy demands, talent shortages, stricter sustainability regulations, and mounting downtime risks, change has become non- negotiable. Enter Condition-Based Maintenance (CBM), powered by AI and fast becoming a necessity for ensuring both competitiveness and resilience. Canninah Dladla, cluster president for English-speaking Africa at Schneider Electric, explores this topic further. There’s no doubt that time-based or reactive maintenance models have the potential to expose data centres to unnecessary downtime, inefficient resource use, higher costs, and compliance risks. Additionally, as AI workloads continue to drive demand for greater computational Why traditional maintenance falls short
reached nearly 76% of the population in 2025, with ongoing expansion of both mobile and fixed-broadband services. South Africa is also among the top four African countries capturing the majority of AI startup investment. These figures reveal a vibrant and growing ecosystem but also highlight constraints. According to Mastercard, infrastructure gaps persist, data centre capacity is limited compared with global hubs, and access to HPC resources remains uneven. This context, scarcity of compute and uneven infrastructure, is precisely why AI- accelerated simulation matters. From theory to impact: simulation where it counts Traditional HPC workloads, such as climate modelling or fluid dynamics, typically require vast clusters and long turnaround times. Emerging AI “solvers”, neural models trained on earlier simulation outputs, can replicate outcomes orders of magnitude faster, often running on a single GPU rather than a large supercomputer. In scientific settings, this has already transformed workflows around fusion plasma modelling and particle physics. South Africa can benefit in similarly tangible ways: • Resource-efficient innovation: Local engineering, manufacturing, and materials research can simulate product performance, stress tests, and failure scenarios before committing to expensive prototyping. This cuts costs and accelerates time-to-market for become costly. This is particularly true in sectors such as finance, healthcare, and e-commerce, where outages can cause severe reputational damage and financial loss. According to Uptime Institute, the average cost of IT downtime ranges from $6,000 to $9,000 per minute, with some outages exceeding $1 million. Talent shortages amplify the risk: half of operators (51%) reported difficulty in finding qualified candidates to fill their job openings for the third year running. In addition, Uptime Institute estimates, and based on 25 years of data, human error plays a role in more than 66% of data centre outages. Traditional maintenance typically suffers from three flaws: • Calendar-based servicing wastes resources and fails to prevent unexpected failures. • Contracts often cover only narrow equipment sets, not entire systems. • Technicians may lack the skills or connectivity to manage multi-vendor, multi-site ecosystems.

Surge protection for modern control systems A s industrial automation, smart buildings, and safety systems become increasingly interconnected, the
discharge capability and voltage limitation is essential to ensure both system reliability and long-term equipment protection. Installation and maintenance considerations Ease of installation and maintenance significantly influences the practical suitability of surge protection devices. Features such as push-in connection technology, angled terminals, and compatibility with common conductor sizes help reduce installation time and minimise wiring errors. Integrated test points allow voltage measurements to be taken directly at the arrester, supporting faster diagnostics and routine inspections. The ability to disconnect signal lines simplifies commissioning and servicing. Modular designs, separating the base from the protection module, are increasingly common. In these systems, surge protection components are contained within a pluggable module that can be replaced without tools. Maintenance can therefore be performed safely and efficiently without disturbing field wiring. For PCB-based applications, mountable base components allow surge protection to be integrated directly into electronic assemblies. Remote signalling contacts at the base level enable condition monitoring while conserving enclosure space. High availability is essential in industrial plants and building services installations. Surge protection devices are therefore often designed with fail-open characteristics, ensuring signal circuits remain operational even after the protective element has Operational safety and system availability It is a common habit, but it is also one of the most inefficient ways to cool a home. Traditional air conditioning units that stop and start repeatedly consume significantly more energy than those maintaining a steady temperature. In a landscape where electricity tariffs are rising and grid stability remains a background concern in many
exposure of measuring and control circuits to lightning and surge events continues to grow. Even short-duration overvoltages can interrupt communication interfaces, damage sensitive equipment, and cause costly process disruptions. Effective surge protection for signal, bus, and communication lines has therefore become a core design requirement in modern electrical and automation installations. One example of how this challenge is addressed in practice is the BLITZDUCTORconnect range from DEHN. It reflects current design approaches that combine high discharge capacity with compact construction for control and instrumentation systems. Universal combined arresters for critical circuits Measuring and control circuits often require protection against both direct lightning currents and induced surge voltages. Combined lightning current and surge arresters are commonly used for this purpose, particularly on signal lines, bus systems, and telecommunication interfaces. Devices in this category are typically designed to withstand lightning current impulses of several kiloamperes (10/ 350 µs) while also handling high nominal and maximum surge currents (8/ 20 µs). This enables them to manage demanding transient conditions found in industrial environments. Maintaining a low voltage protection level is equally important. Sensitive terminal equipment in automation, instrumentation, and communication systems can be vulnerable to excessive residual voltages. Achieving the correct balance between
reached end of life. Secure locking mechanisms help prevent accidental removal during operation, while still allowing controlled replacement during maintenance. Resistance to vibration and mechanical shock is important in industrial environments subject to movement or impact. Effective earthing and bonding networks remain fundamental to surge protection performance. Designs that provide reliable lightning-current-capable connections via standard 35 mm DIN rails support dependable bonding under severe transient conditions. Visual status indicators that do not rely on auxiliary power allow rapid on-site condition checks. Remote signalling modules enable integration into central monitoring or building management systems, supporting proactive maintenance and reducing the risk of unnoticed protection failures. Compact construction and compliance Space in modern control panels and switchgear assemblies is increasingly limited. Surge protection devices with narrow widths that protect multiple signal lines within a single module offer clear advantages in high-density installations. Compliance with international standards and certifications such as UL, CSA, SIL, ATEX, IECEx, and CCC remains essential, particularly for projects involving hazardous
locations or global supply chains. Dedicated solutions for intrinsically safe circuits further extend applicability in potentially explosive atmospheres, where electrical safety and surge coordination must be carefully aligned. part of a broader lightning and earthing strategy. Applications range from building automation and HVAC systems to safety and security installations. By combining high discharge capacity, controlled protection levels, modular construction, and robust A system-based approach Surge protection for control systems forms mechanical design, modern signal line arresters support a coordinated approach to protecting today’s interconnected control infrastructure.

A smarter way to cool homes As temperatures remain high across the country, South African households face a familiar dilemma: how to stay cool without the electricity bill skyrocketing. For many, the default strategy is to run the air conditioner at full blast until the room is freezing, then switch it off until the heat becomes unbearable again.

have evolved to address air quality. Air conditioners can become breeding grounds for mould if moisture is allowed to sit in the unit after it is switched off. Newer models now incorporate auto- cleaning functions that automatically dry the heat exchanger, preventing bacteria and mould growth. This ensures that the air being circulated remains clean, preventing the “stale” smell often associated with older units and maintaining a healthier environment for bedrooms and nurseries. Smarter management Efficiency is also driven by visibility. Integration with platforms like the LG ThinQ app allows households to monitor their energy consumption in real time from a smartphone. Being able to see exactly how much power is being used – and having the ability to adjust it remotely or set schedules – shifts air conditioning from a passive appliance to a managed home asset. As South Africans enjoy the summer months, the focus should shift from simply “surviving the heat” to managing the home environment intelligently. Modern cooling is about temperature control, yes, but it is also about balancing comfort with cost-effective, sustainable energy habits.
The shift from ‘off’ to ‘controlled’ The latest generation of residential cooling technology is moving away from this binary “all-or-nothing” approach. LG Electronics South Africa has introduced Active Energy Control (AEC) to its Dualcool inverter range, a feature designed specifically to give users granular control over their power consumption. Rather than simply choosing a temperature, AEC allows homeowners to actively cap the unit’s energy intake. Users can limit the motor’s performance to 80%, 60%, or even 40% of its capacity. This essentially acts as a “dimmer switch” for electricity usage. This is particularly relevant in South Africa. On a mildly warm day, running an AC at 100% capacity is overkill. By throttling the system to 40%, families can maintain a comfortable environment for sleeping or working while minimising the impact on the household budget. It also reduces the startup load, which is critical for homes running on solar inverters, as many households are choosing to become more and more energy independent.
Modern cooling is about temperature control, yes, but it is also about balancing comfort with cost-effective, sustainable energy habits.
