How SaaS Enables Sustainable Supermarkets: Food Waste Reduction and Energy Efficiency
How SaaS Enables Sustainable Supermarkets: Food Waste Reduction and Energy Efficiency

Across the globe, annual food loss amounts total to approximately 1.3 billion tons of waste and 4.4 gigatons of greenhouse gas (GHG) emissions. To put that in perspective: If food waste were a country, it would rank as the third largest GHG emitting country in the world, surpassed only by the United States and China. The average supermarket, which brings in about $35M in annual revenue, will see $526,590 worth of food waste and 3,600 MWh worth of wasted energy use, where about 2,000 MWh is used for refrigeration—the equivalent of 170 households. SaaS for temperature monitoring Clearly, there is both an economic and sustainability burden to food loss besides the revenue loss and environmental impact. Luckily, this burden can be eased when using Software as a Service (SaaS), like food temperature monitoring. Supermarkets who monitor their food temperatures will improve their margins and overall profitability by selling food at its full price rather than marked down due to over ripening or close to expiration date. This, in turn, will deliver improved customer satisfaction because supermarkets will be able to continue to stock fresh food while minimizing the sale of old and ripened provisions.Supermarkets who monitor their food temperatures will improve their margins and overall profitability There are many benefits of using SaaS to improve supermarket efficiency, which can help to reduce food waste and lower energy costs in countless supermarkets worldwide. Many of the roughly 50,000 food retail locations that utilize electronics controllers use some level of SaaS technology like Alsense Food Retail Services, the newest cloud offering from Danfoss Climate Solutions for supermarkets and food retail applications. Alsense Food Retail Services is a sustainable, scalable, and secure modern platform that delivers tangible data to improve operational and energy efficiency while optimizing the performance of food retail operations. Its technology is engineered to provide supermarkets with actionable insights that allow you to track refrigeration asset performance, respond to alarms, integrate 24/7 monitoring, reduce energy consumption, and more to deliver savings as high as a 40% reduction in food waste and 30% decrease in energy costs. Examples of food loss prevention with Alsense Food Retail Services The sensor in the meat fridge notices a high temperature and submits an alarm to the cloud The alarm is analyzed by the Danfoss Enterprise Service Team (Managed services) The reason for the alarm is determined and a service provider is contacted The service provider is dispatched to the supermarket to fix the issue in the meat fridge to avoid food loss Danfoss’ advanced algorithms detect if the refrigeration systems are running efficiently or if they are over consuming energy Alsense Food Retail Services is a sustainable, scalable, and secure modern platform that delivers tangible data to improve operational and energy efficiency while optimizing the performance of food retail operations aktiv & irma, a supermarket in North Germany, has shown significant savingsWithout SaaS, the store’s ROI will take much longer than if you rely solely on the hardware as part of the Alsense Food Retail Services pilot program. In collaboration with Danfoss, they installed a solar photovoltaic system, storage system, and a charging station for guests. All major assets in the supermarket system are linked through the Alsense Food Retail Services cloud to manage loads and eliminate unnecessary peaks to best use each store’s energy. Regulating energy levels is accomplished through a variety of methods that offer potential savings: Load shifting: As high as 20 kW in additional peak reductions ($1,758.30 potential savings). Compressor curtailment Solar: 112 MWh electricity produced ($16,410.80 savings) Battery: Grid demand reduced by 40 kW ($3,516.60 savings) Peak load shaving: Charging station is throttled if needed to maintain target max peak level in the store. ($2,344.40 potential savings) aktiv & irma saved about 15% in additional energy costs and reduced over 70 tons of CO2 for a total savings of $20,168.80 compared to other supermarkets. For supermarkets that are considering marrying SaaS with their hardware expenditure, the return on investment (ROI) will depend largely on their level of SaaS investment. Without SaaS, the store’s ROI will take much longer than if you rely solely on the hardware. To put it simply, the more robust the SaaS program, the quicker supermarkets will see a return on the overall system investment. Alsense Food Retail Services? A zero-net, even net positive, billable energy supermarket is possible. The prerequisites to make these savings happen are based on energy efficiency, particularly reducing overall consumption and onsite heat and electricity generation and storage. Energy arbitrage services can enable energy bill optimization. Essentially, this means that energy can be stored in a battery and used when prices in the grid are high.Precooling can also be used to cool down cabinets before prices increase Precooling (curtailment) can also be used to cool down cabinets before prices increase. Another option is to turn off compressors for as long as possible when the energy prices are high. This means temperatures will drift upwards, so turn on the compressors before the temperature compromises food quality. Lastly, supermarkets have further potential to balance the grid via fast Frequency Response, peak Load Shifting, and seasonal Buffering. SaaS technology, like Alsense Food Retail Services, is a strong compliment to hardware assets that can help supermarkets achieve higher profitability and food loss and waste reduction. If a supermarket aims to go zero- or positive-net, the solution is to invest in both hardware and SaaS.

Intelligent HVAC Solutions: Enabling a Safe Return to Work
Intelligent HVAC Solutions: Enabling a Safe Return to Work

Having spent the last few months working from our sofas, dining tables and ironing boards, many of us have become accustomed to the world of remote working. But we’ve now arrived at a point where many businesses are starting to reopen their doors or have plans to do so in the near-future. Employers will be hoping that a return to work will prove productive, reinvigorating the workforce and driving growth. To this end, however, they will need to instill confidence by demonstrating how they can keep employees safe and comfortable. Bringing employees back to work will be complex. For a start, businesses have had to implement a large number of new safety measures in response to COVID-19. However, ensuring safety in the workplace goes beyond adhering to social distancing measures and anti-bacterial cleaning stations. Behind the scenes, heating, ventilation and air conditioning (HVAC) play a crucial role in facilitating a safe workspace. Whether it’s the systems implemented to limit the spread of the virus, the ongoing servicing of these systems or their wider environmental impact, HVAC solutions and facilities managers (FMs) rest at the heart of a safer return to work. Embracing new strategies for clean air Walking in the building through a new automatic door, most office workers will be greeted with a queue for the lifts and plenty of signage reminding you to sanitise your hands and keep your distance. Some may have their body temperature scanned by a thermal detection camera on entry, which could also count how many people enter to ensure numbers are safe. Others could be met with an anti-virus access point that scans your face using facial recognition rather than a pass, and enforces hand hygiene by dispensing sanitiser before the lifts will open.  Behind the scenes, heating, ventilation and air conditioning (HVAC) play a crucial role in facilitating a safe workspace All of these measures, however strict, are part of the new normal: ‘contactless’ buildings. Designed to limit the potential spread of COVID-19, facilities managers have plenty of options when it comes to keeping people safe. But not all of them are so apparent when entering a building. Some of the most important measures are those we can’t see. A healthy and safe working environment has always relied on a building’s HVAC infrastructure – temperature control, good air flow, and a reliable level of comfort are top of most office workers’ priority lists. But the pandemic has taken this to a new level of importance. As a critical part of their wider health and safety plan, facilities managers can look to identify strategies to increase clean air levels further. This could include increasing outdoor air circulation to decrease pathogen exposure, with smart air handling units. These will enable managers to bring in more outside air to displace potentially contaminated air, by increasing ventilation and air change rates.  Improving Filtration Methods Improving filtration methods is another possibility, by adding additional filters including high efficiency filters and HEPA filters, to trap more particles and increase the percentage of clean air in a building. Portable HEPA solutions are also an option for those who need more flexibility. In addition to air filtration and circulation, it is also possible to use UV-C lighting to effectively ‘disinfect’ the air or surfaces, using ultraviolet germicidal irradiation (UVGI) to inactivate viral microorganisms. These can be installed brand new or retrofitted into existing facilities, to reduce costs for FMs and speed up implementation. These innovative uses of HVAC to limit the spread of infection could have a huge impact on the health and safety of occupants in any building – and this is by no means limited to offices. Within healthcare and laboratory facilities, for example, solutions like room pressurisation, air change rates, humidity and temperature controls are all critical to reduce contamination in the air and on surfaces. A healthy and safe working environment has always relied on a building’s HVAC infrastructure Safety is an ongoing process No matter which HVAC solutions a facilities manager chooses, it’s not a case of installing them and then waving goodbye. As with any good health and safety strategy, constant monitoring is crucial to ensure building occupants are well looked-after – and this also ensures you can get the most out of HVAC investments. For some this means keeping a close eye on how your HVAC equipment runs, to ensure that they’re reaching optimum performance and delivering the best ROI. Working with a partner who can provide continuous service and monitoring is critical, so that the pressure is off FMs themselves. Especially now, having remote monitoring capabilities is an added bonus, so that minor issues can be fixed without an engineer having to visit the site.  For those with smart technologies in place, such as smart connected chillers, FMs may rather be reliant on predictive maintenance and monitoring tools, which use AI and automation to predict issues before they arise, and ensure equipment runs reliably and downtime can be minimised. Whether in person or remotely, good quality service and maintenance of HVAC equipment goes a long way – both to get the best return on investment, and to keep buildings as safe and comfortable as possible. Enabling a smarter and more sustainable workplace HVAC has always been critical to keeping employees happy and healthy at work – but for a long time this has had a negative impact on the planet. Inefficient HVAC systems can give a building a much bigger carbon footprint than it would ideally have.  75% of organizations plan to increase their investment in energy efficiency and smart building technologies Last year, our Energy Efficiency Indicator survey found that 75% of organizations plan to increase their investment in energy efficiency and smart building technologies. The opportunity, then, to overhaul HVAC systems in order to limit the spread of COVID-19 is also an opportunity to invest in more efficient, greener HVAC technologies, built for the future. Taking a holistic approach to your HVAC equipment is the best way to do this, to ensure efficiency gains can be made across an entire building or estate, by connecting intelligent systems. Chillers, for example, with efficiency and intelligence built in as standard can reduce energy use and carbon emissions for a building, or collection of buildings, helping FMs meet energy targets and keeping costs low. Choosing the optimal HVAC system Under current circumstances, the decisions made by FMs are pivotal in enabling business continuity and will ultimately impact building occupants’ comfort and safety. It should therefore come as no surprise that businesses are paying close attention to every move FMs make. Choosing the optimal HVAC system for your building and ensuring regular servicing and maintenance will prove cost-effective and energy efficient. Not only this, but smart HVAC technologies go a long way in enabling a safer, productive and more sustainable working environment. By picking the right tools for the job, businesses of every type can position themselves for growth while remaining as safe and secure as possible.
