Pete Mills, Commercial Technical Operations Manager at Bosch Commercial & Industrial outlines how cities are using heat networks to achieve UK carbon emission targets. Heat networks, or district heating, are becoming an ever-greater part of our industry’s involvement in larger scale schemes. The ability to help the decarbonization of heat both now and in the future has made them an attractive solution to the new-build sector, as well as those undergoing deep renovation works. Net zero 2050 The UK’s net zero 2050 target may seem like a long way off. But steps need to be made now in order to reach this, something that our leading cities have recognized. Many have set their own carbon targets to ensure they stay on track. This is why heat networks’ ability to provide efficient heat and hot water to multiple buildings (and as the name suggests, whole districts) is a particular reason why many cities up and down the country are turning to them as a solution. What are heat networks? Generally, heat networks are defined as a system of supply pipes with a centralized heat generator (Energy Centre) that serves multiple domestic or non-domestic dwellings. These are usually in different buildings, but sometimes within a single large building like an apartment block or a university campus.District heating is often used to describe larger scale systems District heating is often used to describe larger scale systems of this sort, where there will be many buildings connected over a larger geographic area. In these systems, although the heat is provided ‘off-dwelling’, it is also common to have more than one energy centre. The principle is that energy for heating (and sometimes cooling) is supplied through the system of pipes, with each individual user being metered for the energy they use. Minimize pipe lengths Heat networks offer a number of advantages but are best suited to areas where there is high heat density, that is to say where there are multiple ‘households’ close together in order to minimize the length of pipes within the network. One of the key advantages for heat networks is their adaptability to use any form of heat generation. A key advantage from an environmental perspective is that they make use of waste heat, from sources such as electricity generation, waste incineration and industry. Heat networks are defined as a system of supply pipes with a centralized heat generator that serves multiple domestic or non-domestic dwellings The scale of the combined heat requirements of all these dwellings also helps the inclusion of renewable energy sources, which may be more difficult and costly to achieve at the individual dwelling level. Overall, their flexibility to use whatever heat source is available, makes them easier to decarbonize in the future.Other key benefits for Local Authorities and Housing Associations have been the elimination of individual gas appliances within dwellings. This has significant cost savings reductions for Local Authorities and Housing Associations where gas landlord checks are eliminated, along with the issues associated with access. City developments Today City Councils and developers are opting for heat networks to provide the heating and hot water for new redevelopment projects. The largest of these is the ambitious Leeds Heat Network, which once completed is set to be one of the UK’s largest new heat networks, connecting 1,983 council homes and numerous businesses in Leeds. The first scheme under the City Region’s District Heating program, the green initiative looks to reduce carbon emissions for the area as well as energy bills for the residents living there.The green initiative looks to reduce carbon emissions for the area Even more innovative is how the network will connect to the Leeds Recycling and Energy Recovery Facility, which burns black bin bag waste to generate heat. In theory this would make the network fully sustainable. There will be back-up support from efficient Bosch Commercial & Industrial boilers, which will only be switched on when required, say the colder months where the need for heat is higher. Climate change targets An hour’s drive away from Leeds is the city with one of the most ambitious climate targets in the UK. Manchester intends to be carbon-neutral, climate resilient and zero waste by 2038 – 12 years before the overall UK net zero 2050 target needs to be hit.To help achieve its ambitions, work has been taking place on the Manchester Civic Quarter Heat Network (CQHN). Manchester hasshown the versatility of heat networks due to the number of commercial buildings it will support The project will generate low-carbon power, heat and hot water for initially six council buildings and some residential properties with the possibility for the network to grow and connect further buildings across the city centre. Some see district heating as a solution solely for residential purposes, however Manchester have shown the versatility of heat networks due to the number of commercial buildings it will support. The project itself has also given Manchester a new landmark, the impressive ‘Tower of Light’, which incorporates the five flues from the technology powering the network. This beacon not only represents the city’s commitment to reducing its carbon footprint but also the innovative nature of district heating. Heating Battersea Power Station The final example lies in the Capital and may be one of the most famous developments in the UK at the moment. Battersea Power Station is not only one of the most iconic landmarks in London, but also the center piece of one of the most high-profile, large scale mixed-use redevelopment projects ever undertaken in the Capital.Battersea Power Station is a high-profile, large scale mixed-use redevelopment project The project involves the development of a district heating and cooling network, with a two-level underground energy centre – one of the largest of its kind. This complex heat, cooling and electricity network will continue to expand as the project continues to undergo its development stages. Looking ahead These are just a few examples of cities taking advantage of district heating and its many benefits, but near all cities in the UK have multiple heat network projects underway. Like with most innovations, smaller urban areas should then follow suit. The importance of district heating will no doubt become more and more prominent. Its ability to power whole areas and multiple buildings can already help efficiency levels, however its potential may be even greater in the future. One key energy transformation that is looking more and more likely is the decarbonization of the gas grid to hydrogen blends and ultimately 100% hydrogen. If these can be utilized in heat networks then the benefits will definitely put us and UK cities in a good place as we continue our journey towards net zero.
As the UK continues to battle through the coronavirus crisis, HVAC business owners and installers can be putting some of their enforced downtime to good use. This period of subdued trading is a rare opportunity to get into better shape for when economic activity picks up. One way of doing this is by sharpening the focus on markets which promise strong growth – and few markets are growing faster than that for heat pumps. The potential here is huge. Some 28,000 heat pumps are currently installed in the UK every year, and before the pandemic this number was rising annually at a rate of 15-30%. That equates to sales doubling every three to five years. New-builds account for the majority of those sales, but 30% are retrofits, and about 30% of those retrofits are in private residences. This means there’s a big opportunity for doing conversions from oil boilers to heat pumps at rural homes not connected to the gas grid. The ‘New Normal’ and Heat Pumps It is only realistic, of course, to expect a lingering dip in HVAC sales of all kinds, including heat pumps, until the post-pandemic world gets back on its feet. But when we do turn the corner into the ‘new normal’, heat pump sales will again climb strongly. One reason for this is consumer demand, the other is government policy. End-users are now increasingly aware of the dangers and disruptions threatened by carbon emissions and climate change – informally known as ‘the Blue Planet Effect’ – and more are being guided by their consciences to make environmentally-responsible heating choices. An Expected Spike In Demand Many end-users are also encouraged by the prospect of receiving payments from the government through the Domestic RHI tariff. When we do turn the corner into the ‘new normal’, heat pump sales will climb strongly If RHI tariffs are the carrot, however, the government is also going to wield a big stick. The Chancellor’s spring statement last year dropped the bombshell that low-carbon heating systems, not fossil-fuel heating, should be installed in all new homes built after 2025. Though this policy might perhaps get slightly delayed and diluted, there can be no doubting that radical change is on the way. With all this in the pipeline, the industry should be preparing now to cope with the increased demand. But there’s some way to go: of the UK’s 120,000 registered gas engineers, merely 600 or so are MCS-registered to install heat pumps. Many more will be needed. MCS Certification Some installers are already recognizing this opportunity. Some 28,000 heat pumps are currently installed in the UK every year, and before the pandemic this number was rising annually at a rate of 15-30% This is evident in the heightened level of interest in the one-day introductory heat pump courses run nationwide by the Viessmann Academy. These courses provide a useful overview of what heat pump installations involve, helping participants decide whether or not they would like to go on to qualify with the MCS quality assurance scheme. This is a crucial decision, because having MCS certification is an obligation when installing equipment eligible for Domestic RHI payments. Some course participants decide to take the next step to MCS certification straight away, others decide to wait a while – but standing still in a fast-moving market can mean getting left behind! F-Gas Certification So what else must HVAC businesses and installers consider about heat pumps, in order to stay ahead of the game? In addition to MCS certification, F-Gas certification is also necessary when split air source heat pumps are installed. This is because the outdoor and indoor units have to be connected on-site with refrigerant pipework. Some installers choose to get F-Gas certified themselves, others sub-contract this part of the job to someone who’s suitably qualified. Of the UK’s 120,000 registered gas engineers, merely 600 or so are MCS-registered to install heat pumps It is possible to sidestep this need, however, when it is appropriate to install a monobloc heat pump – and the widening choice and affordability of monobloc designs is making them appropriate for a wider range of properties. A good example of this is Viessmann’s new Vitocal 100-A, an outdoors unit which has no need for a complementary indoor unit and is also easy to install because most components are integrated in the unit. New, compact and affordable air source heat pumps such as this, offering much-needed space-saving solutions for urban homes, are another reason why the heat pump market will boom. The Challenges Of Heat Pump Installation Though technological advances are making things easier, installing a heat pump isn’t ever going to be quite as straightforward as replacing an old boiler with a new one. Before starting an installation, first it is necessary to assess whether a heat pump is suitable for the property. This means checking that the property is well-enough insulated; checking the existing system’s radiators, which may need supplementing or replacing with bigger radiators or underfloor heating because of the lower flow temperatures of a heat pump system; and calculating the required size of the heat pump according to the building’s heat loss (and not including hot water demand). This period of subdued trading is a rare opportunity to get into better shape for when economic activity picks up At the installation stage itself, much of the work will be familiar to boiler installers, though weather compensating controls are obligatory for all MCS-approved work and as part of building regulations Part L. It’s also important to note that planning permission requires minimum distances between the heat pump’s outdoor unit, the plot’s borders, and neighboring properties. If this seems complicated, it doesn’t have to be: some heat pump manufacturers provide a calculator to simplify the task. Now Is The Time To Be Proactive Just as installers need a little time to assess whether a property should switch from a boiler to a heat pump, end-users also need a little thinking time, to consider adopting a technology new to them. By being proactive, HVAC businesses and installers can reap what they sow When customers get in touch because their existing boiler has broken down, the pressure for a quick fix can rule this out. But right now, when many of us have time on our hands, there’s the chance to inform customers of alternative heating solutions before their boiler needs replacing. Taking such pre-emptive action, by emailing information or mailing leaflets to customers, does require a little effort, but at least now there’s the time to do it. We are heading into a new era which will see boiler sales decline while heat pump sales rise. By making preparations for these profound changes, and by being proactive, HVAC businesses and installers can reap what they sow.
Strategic electrification encompasses a host of solutions aimed at decarbonizing Earth’s atmosphere, decreasing pollution and reducing the costs of modern comfort and technology. Also known as “beneficial electrification”, this movement requires increased energy efficiency and end uses powered with electricity from cleaner grids and renewable sources. The movement will transform both the built environment and society’s modes of transportation. Despite the complexity of its challenges, strategic electrification can no longer be dismissed as a niche or a possibility of the far future. The movement is happening now, driven by a mix of public and private entities on various levels proceeding along voluntary and mandatory paths. What Is Being Done? In the absence of formal federal action on climate change — including the Clean Power Plan and Paris Accord — cities, states, municipalities and utilities are continuing to develop their own decarbonization strategies. There are now nearly 450 cities in the U.S. that have committed to 80% carbon reductions by 2050 The goal is to achieve this through a variety of policy mandates such as taxes, building codes and portfolio standards. This is in addition to voluntary approaches that can include utility rebates and construction decisions such as choosing a passive house design; updated building efficiency targets; system-specific electric mandates; and comprehensive gas bans. Just recently, Santa Cruz became the 30th city or county in California to enact a measure limiting or prohibiting the use of natural gas in new construction, according to an article published by Yale Environment 360. The Carbon Neutral Cities Alliance Many organizations have rallied around these strategies. For instance, the Carbon Neutral Cities Alliance (CNCA) is one of the many organizations that have rallied around the strategies that must be employed to reach carbon neutrality. CNCA is a collaboration of leading global cities working to cut greenhouse gas emissions by 80-100% by 2050 or sooner. They’ve adopted some of the most aggressive GHG reduction targets undertaken anywhere by any city. Mitsubishi Electric Trane HVAC US was one of the organization’s first HVAC participants, providing expertise and product knowledge to support their continued efforts. Major CNCA cities include New York City, NY, San Francisco, CA and Washington, DC. If We Don’t Electrify, How Could That Impact the Environment? Cities are working aggressively to reduce fossil fuel use because our CO2 levels are trending in a dangerous direction. As a naturally-occurring greenhouse gas (GHG), CO2 helps earth retain enough warmth to sustain life but too much can lead to excessive warming. If our global energy demand grows and we continue to use fossil fuels in the same way, the average amount of atmospheric CO2 will likely exceed 900 ppm by the year 2100 For 800,000 years, before the Industrial Revolution and the widespread adoption of fossil fuel-burning technologies, the highest global average atmospheric amount of CO2 was 300 parts per million (ppm), according to the National Oceanic and Atmospheric Administration (NOAA). 407 ppm is the current average amount, per a trend report published by the Global Carbon Project. The NOAA also reports that if our global energy demand grows and we continue to use fossil fuels in the same way, the average amount of atmospheric CO2 will likely exceed 900 ppm by the year 2100. As atmospheric CO2 increases, the global temperature also increases, potentially reaching 1.5° C above pre-industrial levels between 2030 and 2052. At this temperature, the majority of climate scientists expect environmental changes to include rising sea levels, increased flooding, droughts, extreme heat, wildfires and new risks to human lives, infrastructure and biodiversity. According to the U.S. Energy Information Administration, buildings (residential and commercial) account for nearly 40% of the nation’s total energy demand — and about 75% of all electricity use. Where Does The HVAC Industry Fit In? Worldwide, all-electric heat pumps are the most popular technology for decarbonizing heating and cooling. VRF heat pumps and heat-recovery systems contribute to lower carbon footprints and benefit strategic electrification by reducing overall costs for commercial building owners, consumers and society. Instead of burning fossil fuels, a VRF heat pump provides heating to zones by introducing ambien heat its outdoor unit extracts from the air or a nearby water source. During cooling, VRF heat pumps reverse this process as indoor units transfer heat from zones to the outdoor unit which then rejects the heat. Until recently, some specifiers in northern regions felt obligated to select a gas-powered furnace or electric resistance for heating systems due to air-source heat pump derating at sub-freezing temperatures. Today that’s not the case. Mitsubishi Electric Trane HVAC US' SUZ universal outdoor unit uses Hyper-Heating INVERTER technology Air-source VRF systems now use advances such as flash-injection technology in the compressor to offer unprecedented levels of capacity and efficiency at low outdoor ambient temperatures. This creates opportunities to replace fossil-fuel-burning equipment in more regions than before. VRF heat pumps and heat-recovery systems help building owners, architects and engineers solve challenges associated with decarbonizing the electric grid as well as emerging building codes, standards and legislation related to decarbonization. Federal standards and programs like ENERGY STAR®, tax credits and utility rebates will continue accelerating adoption of energy-efficient alternates to fossil fuel burning systems. The Decarbonization Challenge The decarbonization challenge is significant and complex, but change is happening now. At Mitsubishi Electric Trane HVAC US, we’re passionate because we recognize the dangers of climate change and acknowledge the significant role we can play in decarbonization efforts. The decarbonization challenge is significant and complex, but change is happening now Legislation, codes, financial incentives, product innovations and environmental advocacy encourage the transition from fossil-fuel-burning equipment and will continue to evolve. We’re doing our part by researching, developing, manufacturing and providing training for the all-electric heat pumps and VRF systems that enable society to enjoy improved comfort while reducing both costs and carbon emissions. Ultimately, strategic electrification can only be successful if it’s associated with personal comfort and prosperous communities.
ASHRAE, a global society advancing human well-being through sustainable technology for the built environment, announced a move to its new global headquarters, located at 180 Technology Parkway, Peachtree Corners, Georgia. The Society began renovations in January 2020 on an existing 66,700 ft building, originally built in 1978, on 11 acres of land. Located 10 miles north of its previous headquarters building, ASHRAE joins other innovation and sustainability-focused organizations based in the popular Technology Parkway corridor. Net-Zero energy buildings “ASHRAE’s new global headquarters is a prime example of how we are helping to pioneer a movement that many expect will ultimately make net-zero energy the ‘new norm’ in sustainable design and construction,” said ASHRAE Building Ad Hoc Committee Chair Ginger Scoggins, P.E. “Although new construction of net-zero energy buildings make a lot of headlines, reuse of existing structures is a basic tenet of sustainability – the energy performance of existing buildings must be addressed to substantially impact the 40% of primary energy consumed by buildings.” “ASHRAE’s goal for this project was to renovate a three-story 1970’s era, cheap energy period building into a high-performing net-zero-ready facility in a cost-effective way that can be replicated in the built environment industry,” said Technical Advisory Subcommittee Chair Tim McGinn, P.E. The photovoltaic (PV) system design is currently in progress. The building will be on its way to fully net-zero energy by March 2021 upon the completion of the PV system installation. Digitally connected solutions The headquarters building incorporates several digitally connected solutions such as remote monitoring" Focusing on the Society’s 2020-21 theme, “The ASHRAE Digital Lighthouse and Industry 4.0, the headquarters building incorporates several digitally connected solutions such as remote monitoring and analysis of building performance, with online dashboarding for transparency and advanced Building Automation System (BAS) integration with other systems, such as ASHRAE’s meeting reservations systems.” Other solutions include a digital twin and Building Information Model (BIM), innovative mechanical systems visible through open ceiling around radiant panel clouds and advanced conferencing systems designed to serve as a ‘digital lighthouse’ teaching resource. “ASHRAE’s first-of-its-kind headquarters building was designed as a living showcase of what's possible through technology integration to increase efficiency, protect people and property, and enhance the occupant experience,” said 2020-21 ASHRAE President Charles E. Gulledge III, P.E. “In addition to supporting ASHRAE’s technical standards, innovative product integrations from our generous donors also provide a scalable and repeatable model for a net-zero energy building design.” Fresh air distribution system Examples of technical features include: Radiant ceiling panel system: This is used for heating and cooling & dedicated outdoor air system for outdoor air ventilation with enthalpy heat recovery. Overhead fresh air distribution system augmented with reversible ceiling fans in the open office areas and displacement distribution in the learning center. Six water source-heat pumps (WSHPs): There are four on basement level and two on upper level atrium that will be used to condition these spaces. Demand Control Ventilation (DCV): This will be used for high occupancy spaces in the meeting and learning center. Air distribution is constant volume in office areas and provided by fabric duct, reducing diffuser count and duct branches. Modeling Energy Use Intensity of 17 kBtu/sf/yr. On-site electric vehicle charging stations available for guests and staff. Roof-top and ground mounted photovoltaic solar energy system planned for installation March 2021. 18 new skylights and reconfigured window/wall ratio. Useful daylight illuminance (>300 lux) at the work plane Window Wall Ratio (WWR) 79.9% Existing – New WWR east/west 33.5% - north/south – 41.9%. Prior to the COVID-19 pandemic, ASHRAE had already planned to provide 30% more outside air to the building than the required minimum ventilation rates from ASHRAE Standard 62.1 - Ventilation for Acceptable Indoor Air Quality and will implement other applicable guidance that has been developed by the ASHRAE Epidemic Task Force (ETF) for commercial office buildings. Building occupant health The building is located in a forest setting, close to hotels, restaurants and walking trails The building is located in a forest setting, close to hotels, restaurants and walking trails. A large deck overlooking a lake adjacent to meeting rooms can be fully enjoyed on sunny days. ASHRAE’s headquarters is 12 minutes and 6.2 miles from the Doraville MARTA station for easy access to Atlanta Hartsfield International Airport. The Society’s approximately 110-person staff officially moved into the building at the beginning October. “This move represents another significant milestone for ASHRAE,” said ASHRAE Executive Vice President Jeff Littleton. “In addition to showing our commitment to building occupant health and comfort, our new headquarters building will enable us to provide industry-leading support and service to our global volunteers, while driving innovation that will push our goal of sustainability in action forward.” Successful building campaign A team of ASHRAE volunteers led a highly successful building campaign to garner support for the renovation project. Thirty-one corporate donors committed more than $9.7 million in monetary support and gifts of equipment and services. ASHRAE thanks the following industry partners for their high-level support of the new global headquarters renovation project: NIBE, Cisco, Arkema, Daikin, Price Industries, Belimo, ClimateMaster, ClimaCool, Bell & Gossett, Big Ass Fans, Victaulic, Uponor, Mitsubishi Electric Trane, NTT and PlaceOS. Donors to the building campaign will be listed online and recognized in a special new headquarters commemorative magazine to be published in January 2021. Sustainable built environment ASHRAE’s new global headquarters is an example of an effective built environment" Additionally, ASHRAE members have given over $500,000 to date. In total, ASHRAE has received over $10.2 million from generous stakeholders, making a strong statement about their commitment to ASHRAE’s mission and to a shared vision of a healthy and sustainable built environment for all. “ASHRAE’s new global headquarters is an example of an effective built environment that fully considers the importance of effective operations by installing the systems and equipment in a manner that facilitates operation and maintenance,” said 2019-20 ASHRAE Presidential Member and Building Ad Hoc Committee Member Darryl K. Boyce, P.Eng. “We are grateful to our donors for their generous support and partnership. It is this support that not only shows our donors’ alignment with ASHRAE’s sustainability goals, but helps us to address the challenges of designing and operate buildings in a technology driven environment.”
Daikin Singapore ("Daikin") announced that it has signed a Memorandum of Understanding (MOU) with SP Group ("SP") to provide Singapore's first large-scale residential centralized cooling system at Tengah. The MOU includes joint research and development, product innovation and marketing opportunities in Tengah, and future collaborative opportunities in Singapore and the region. The partnership builds on SP's expertise and strong track record in operating one of the world's largest underground district cooling system in Marina Bay and Daikin's strength in the air-conditioning industry through its Chilled Water System Equipment including chillers, water pumps, fan coil units, and maintenance services. smart energy solutions "Daikin is enthusiastic about this collaboration with SP Group. Daikin has designed unique equipment for this project in Tengah. With this collaboration, we look forward to working together to make the Tengah town energy-efficient, green and cool," said Mr Masanori Togawa, President and Chief Executive Officer, Daikin Industries, Ltd. Daikin will deploy its Building Management System to monitor and control Tengah's centralized cooling system Mr Stanley Huang, Group Chief Executive Officer, SP Group, said, "SP Group aims to enable a low-carbon, smart energy future by integrating sustainability into the everyday life of the residents. Through this collaboration with Daikin and building on SP's strong track record in providing smart energy solutions in Singapore, we look forward to helping households enjoy the reliability and energy efficiency of centralized cooling." low-carbon smart energy towns The centralized cooling system for residential Housing Development Board projects aims to optimize the energy consumption for air-conditioning needs and reduce the urban heat island effect. Around 22,000 households stand to benefit from this initiative and Tengah will be the model for low-carbon smart energy towns in Singapore. Daikin Singapore will deploy its Building Management System (BMS) to monitor and control Tengah's centralized cooling system. Following the acquisition of BMS Engineering last year, Daikin is now able to provide the technical equipment as well as maintenance of systems as a one-stop solutions provider. This collaboration marks a first for Daikin. The partnership with SP is part of Daikin's longer-term growth strategy to meet the changing requirements of energy players, sustainable architecture projects as well as the rising number of social-conscious citizens in need for more adaptable accommodations. Going Green Regionally Daikin and SP will monitor and optimize the model for Tengah and explore future opportunities to replicate the same reliable and efficient system in other parts of Singapore and the Southeast Asia region. This builds upon Singapore's ongoing roadmap for greener buildings as well as the longer-term vision for a Singapore Smart-city that includes sustainability in its advocacy.
A new cloud-based solution enables HVAC professionals to access VRF systems remotely to diagnose service issues and lessen the time and costs of providing service. CoolAutomation’s Remote HVAC Service Solution enables HVAC service providers to remotely troubleshoot issues by analyzing real-time and historic data trends and analysis. They receive automatic error and anomaly notifications in their office or on their mobile phones. “The remote service solution provides the tools that HVAC service providers need to offer remote services to their existing clients while attracting new customers who understand the value of remote service for their business,” says Roy Muchtar, VP of Products at CoolAutomation. variable refrigerant flow On site, a CoolAutomation CloudBox connects directly to the VRF and links to the cloud via routers and the Internet. The box shares data on the operation of the VRF to the cloud, where a subscription service enables it to be analyzed to determine any problems. The service solution can connect to any major VRF (variable refrigerant flow) system, including Mitsubishi, Daikin, LG, Samsung, et. al.; and can connect to VRF units from multiple manufacturers in case a customer has installed more than one. The cloud solution begins monitoring information from the VRF at the time of installation If a service provider is migrating from one brand to another, the cloud solution can operate with both if there is a period of overlapping systems. The experience is the same regardless of the VRF brand. The cloud solution begins monitoring information from the VRF at the time of installation, providing a benchmark of how the equipment operates when it is first commissioned. Over time, the technology collects and stores additional data on how it continues to function. remote service solution The service provider receives an email or an alert on their smart phone if something is wrong or if a component is operating outside a defined parameter. The remote service solution also shortens the cycle of service and support. In case service is needed, the provider can diagnose the problem remotely before he or she visits the site; in some cases, remote service can solve the problem. If any anomaly surfaces, the service provider has access to the entire history of system operation to show them what has changed and when. If a site visit is needed, the technician can arrive on site knowing what the problem is and with a plan (and required materials) to solve it quickly. There is no need, for example, for one site visit to diagnose a problem and then a second visit to fix it. cloud-based approach Knowing ahead the complexity of a problem helps service providers decide which technicians (e.g., what level of expertise) to send to the site. The cloud-based approach can also maximize productivity of a service company’s most experienced technicians. A knowledgeable technician can address multiple customer issues in less time, diagnose the problems remotely, and then dispatch less experienced technicians as necessary, knowing exactly what they need to do. The model of sending a technician on site to address every service call, from small to big, will be challenging" In short, the remote service solution is another tool in a provider’s toolbox, helping them improve service, lower costs, and benefit their own bottom lines. There are also benefits for any companies seeking to provide “HVAC as a service” – less cost and more dollars go to the bottom line from any monthly subscription payments. remote service capabilities During the COVID-19 pandemic, the benefits of remote service have become even more obvious as a way to minimize customer visits. In fact, in general, end customers increasingly are coming to expect remote service capabilities from providers. “HVAC technical service organizations and HVAC contractors will have to make some transition in the way technical service is being provided because of the pandemic,” says Muchtar. “The model of sending a technician on site to address every service call, from small to big, will be challenging in an environment of ever-changing travel restrictions.” The remote service solution also avoids having to set up an appointment to access a system if the building is vacant (because of coronavirus). Also, any anomalies in system operation are less likely to be noticed if the building is empty, so remote monitoring is even more valuable. From the end customer’s perspective, it is likely a service provider can solve any situation before the customer is even aware there is a problem. The time needed for problem resolution is shorter, and lifespan of the system is longer because small problems are addressed before they cause larger problems. In addition to service issues, the information stored in the cloud provides voluminous data that can be analyzed to yield insights on how the system has been used, the performance of various elements, etc. interpreting larger trends The CloudBox, also used for home automation, is already in use in more than 90 countries A rules engine can aid with analyzing multiple factors to interpret larger trends. Rules can be customized to provide alerts based on specific parameters and/or anomalies, and customers can share a library of rules generated by other users. Alerts may include operational analytics (e.g., if the room temperature goes below 60 for 30 minutes), manufacturer alerts (if something is wrong with the VRF), and maintenance alerts (e.g., filter needs to be changed). The new technology, launched in late June, has been beta testing worldwide for several months, including in the United States, the United Kingdom, Israel and Germany. The CloudBox, also used for home automation, is already in use in more than 90 countries. targeting facility managers Use of the technology will soon be expanded beyond VRFs to connect with chillers and other more traditional HVAC systems; however, additional integration is needed to operate with various brands of chillers, each with a different interface. In addition to the remote service solution, CoolAutomation also offers a control application (for end users). Later this year, the company will be introducing an application targeting facility managers that addresses issues such as scheduling and energy consumption
