2021 Technology Trends In The HVAC Industry
2021 Technology Trends In The HVAC Industry

As we look back at 2020, we are all reflecting on the year that was, and what we have learned from it. In the HVAC space, the year provided us with opportunities for growth and change, as we adjusted to our “new normal.” Here’s a look at some of the HVAC trends we see happening now taking hold as we head into 2021. Advancements and applications in indoor air quality - especially in HVAC space (SF / MF / CRE) 2020 was filled with starts and stops with regards to innovation. Covid-19 halted work in some facilities altogether earlier in the year. The pandemic has brought with it a re-energized interest in the air quality around us, especially in the public sector. There has been a newfound imperative in creating indoor air quality solutions that ensure that air is circulated, sanitized and purified to reduce the likelihood of the spread of sickness. This is a massive issue and 2021 will see growing efforts in these areas and the increased introduction of systems that will purify air quality. HVAC building systems Continued push toward energy efficiency (mainly SF but also CRE) Energy efficiency will be an ongoing issue into the foreseeable future. Once we have looked back at 2020’s carbon emission reductions (because fewer people were flying and driving) there will be no turning back. The same can be said for HVAC. Increased efficiency will continue to be an ongoing pursuit in 2021 and beyond. On average, HVAC appliances consume 48% of a household’s total energy usage. The latest generation of smart thermostats that use the newer 410A refrigerant have brought about reduced energy consumption by up to 35% optimizing how HVAC building systems are operated (reducing the possibility of leaving the AC on too long, and when it’s not necessary to use). convenience and energy savings Increase in supply chain management / platform services HVAC services such as those that collect and manage data including HVAC unit age, efficiency and condition at the property and portfolio level will continue to see increased adoption. These convenience and energy savings they provide is being seen in the multi-family and commercial space, especially with some building owners having been grounded by the pandemic in 2020. New construction had a role in expanding interest in HVAC asset tagging and helping it gain traction in the industry The data gathered by these services can be used in the future to predict HVAC system failures with significant accuracy before they happen. The convenience and potential cost savings acquired by implementing these services will continue to push their popularity into 2021. Additionally, it is interesting to note that new construction in 2020 had a role in expanding interest in HVAC asset tagging and helping it gain traction in the industry. Cataloguing HVAC assets ensures the follow up and guarantees that warranty registration holds and can help track future maintenance during a hold. At the time of sale, the current owner can present true data of the maintenance of these systems, which can increase the current value of the property and can also be used as a tool in negotiation. performing regular maintenance Remote monitoring can be the end to end solution that completes the action behind the alert (CRE mainly) Remote monitoring will continue to see adoption in 2021. Service providers will continue to rely less and less on clients identifying and reporting a problem a heating/cooling issue. The complaint from the tenant may come in some hours after the problem actually starts, and then by the time they get a service request completed, several hours more. And by the time the contractor is on the scene, it is likely more time has elapsed. Remote monitoring also results in regular maintenance, extending the lifetime of a HVAC system. By proactively performing regular maintenance, the overall costs of maintaining a system can be reduced by 40 percent, in addition to ensuring that units are always using the least amount of energy necessary. seamless customer experience Consolidation of HVAC services and equipment - the way people buy - turnkey integrated services One stop shopping for HVAC services and equipment gained popularity in 2020 One stop shopping for HVAC services and equipment gained popularity in 2020 and we will continue to see increased traction in 2021. There are many reasons why developers what to buy equipment directly from the manufacturer, such as convenience, working with a supplier because of its reputation, cost and guarantees on product and services. As more developers buy equipment directly, these manufacturers are responding by helping out with mechanical drawings. This process cuts down the supply chain, allows certainty that correct equipment is quoted, and saves money. The HVAC industry is also turning the corner in becoming more proactive in remediating failing assets and contractors are redoubling their efforts to provide a seamless customer experience increasing customer satisfaction for multi-family communities as well as other means of optimization of services that positively impact tenants, helping increase retention. HVAC providers that can manage the entire process from installation, to job request to invoicing, even reporting and tracking for each job, will be increasingly in demand in 2021.

Inverter Maintenance For Aircon Engineers
Inverter Maintenance For Aircon Engineers

Inverter driven air conditioning is more energy efficient, cheaper to operate and more profitable to install than its non-inverter driven equivalent. Here Neil Ballinger, head of EMEA at automation parts supplier EU Automation, explains how HVAC engineers can maintain the inverters in their customer’s aircon units. Do you remember cross country at school? It was exhausting; miles of seemingly pointless jogging and sprinting and, if the teacher was not looking, walking. If you were unlucky enough to be born before modern safeguarding measures were introduced, it probably also meant getting lost in the nearest woods.Why isn’t every installation an inverter driven unit, instead of the traditional single stage or dual stage models? My PE teacher, who seemed particularly vicious at the time, but in retrospect just knew about sports science than most, used to make us do something called fartlek as well. This meant long distance runs, incorporating elements of speed training by mixing up sprints with jogs and walks. The worst bit was starting to run again after a walk. That is exactly how the motor in your customer’s air conditioner feel if the units you fit are not inverter controlled. The motor has to act just like a runner doing fartlek — it sprints continuously, operating at full speed until the thermostat tells it the room is cool, then it stops. When the room gets warm, it starts again, powers immediately up to full speed and repeats the process indefinitely. Just like a teenage cross-country runner, it is the starting and stopping that is the tough bit. Furthermore, the unit probably doesn’t have to run at full speed to keep the room at the correct temperature, if the motor were inverter controlled it would speed up and slow down as the temperature fluctuates. Why isn’t all aircon inverter driven? We all know that inverter driven aircon is better than its non-inverter driven cousins. It can provide heating as well as cooling and the lifetime cost of use is less for the customer — because their energy bills stay low. The cost of installation is also higher because it is a more complex job, so it works out better for the contractor. It’s a win-win. The research firm Technavio even lists it as one of the key technologies driving growth in the HVAC market in its annual reports every year. So, the only question is, why isn’t every installation an inverter driven unit, instead of the traditional single stage or dual stage models?When contractors contact EU Automation to buy automation parts, for the units they maintain, they have given us another reason: maintenance Cost is a factor, but when contractors contact EU Automation to buy replacement motors and inverters, and other automation parts, for the units they maintain, they have given us another reason: maintenance. As HVAC engineers, we are not necessarily specialists in power electronics, and this makes inverter maintenance daunting. Microcontrollers and IGBTs (Insulated Gate Bipolar Transistors) are not beyond us by any means, but they can be intimidating. Personally, I would back an electrical or heating engineer over an electronics specialist in a problem-solving contest all day long; but that doesn’t solve the problem at hand. Furthermore, while we are experts in air conditioning brands, and know our Daikins and Grees from our Mitsubishis and Fujitsus, we don’t necessarily have contacts at the inverter manufacturers. Amtech, Danfoss, Vacon and Yaskawa are all names we know, but the local dealer for any of them is probably not in your phone book. This is especially true if the unit you need is from a first-generation inverter driven aircon unit and well over a decade old. While we are experts in air conditioning brands, and know our Daikins and Grees from our Mitsubishis and Fujitsus, we don’t necessarily have contacts at the inverter manufacturers Maintenance techniques While inverter maintenance can be daunting, it isn’t difficult. The tools you will need most often are nothing more than a rag and a spanner, while the more esoteric kit is stuff you probably carry anyway, a laptop, vacuum and a Fluke meter. Before you start, remember that while we tend to refer to an inverter as an inverter, the manufacturers themselves, and many of the sources of information online, often refer to them as VSDs (Variable Speed Drives), VFDs (Variable Frequency Drives) or just plain old drives. As a result, when you are searching online for a video to explain something, it’s worth using all three of those terms, alongside the inverter manufacturer’s name and the problem to make sure you get the right result.While inverter maintenance can be daunting, it isn’t difficult When you do move on to maintenance, step one is simple; make sure that the unit is free of dust. This is as easy as vacuuming the heatsink with an ESD (Electrostatic Discharge) vacuum cleaner when you perform routine maintenance or investigate a problem. While you are checking for build up of dust and daily grime, check the filters. They will probably have to be replaced during annual maintenance, but high use might mean they need to be replaced more often. The control panel itself should be well ventilated and free of dust as well, if it isn’t it can overheat, which is the number one cause of inverter damage and the most common reason contractors contact us for replacement units. Before you put your vacuum and duster away, you should make sure that the inverter unit’s location is clean and as sheltered from the elements as possible. Because it’s normally situated on a roof, it’s not going to be perfect, but the units are designed to take a limited battering. That doesn’t mean it’s okay for them to be covered in leaves, surrounded by rubbish or immediately beneath the guttering outlet though! Before you put your vacuum and duster away, you should make sure that the inverter unit’s location is clean and as sheltered from the elements as possible Get out the spanner Once you’ve finished these steps, you are done with dusting for now, it’s time to get out your screwdriver and your spanner. Step one is to make sure the fans on the inverter are operating normally, without noise and with nothing blocking their rotation. The fan keeps the internal components running effectively, just as it does on PC, and if its function is impaired the capacitors will overheat and the inverter will fail.When you install or maintain an inverter on an air conditioning system, it is a sensible precaution to back up the drive parameters to your laptop The next job is to grab your spanner and make sure the power terminals are on tight. Loose connections cause arcing, overheating and even melting of components and are easily checked during any kind of maintenance and repair. While we are still in the realms of the work your apprentice can do with their eyes closed, you should also make sure that the inverter’s removable LCD control pad is stored sensibly and not continually attached to the drive. If it remains attached, there is a chance the display will stay on permanently, which means that when you need it to diagnose a problem, it will probably already be burnt out. Break out the laptop When you install or maintain an inverter on an air conditioning system, it is a sensible precaution to back up the drive parameters to your laptop. It takes minutes and is normally done by using the removable LCD control. In fact, it’s often as simple as selecting ‘PARs’ and then ‘BACKUP’ from the menu. If you struggle, there are lots of videos on YouTube, like this one, which explain the process for each drive. As a result, if the inverter ever does need replacing, you can whip out your backed up parameters and order a new or refurbished one easily, before reloading the parameters to the replacement and getting up and running in no time. Your customers will think you are a power electronics genius, as well as a HVAC expert, and they will be loyal for life; especially of you save them on a hot day! If you follow these simple measures, you will find that the inverters in your customer’s air conditioning units last much longer and no motors will have to run the equivalent of a cross country, thanks to a lack of inverter control.

How Do IoT Sensors Improve Building Performance?
How Do IoT Sensors Improve Building Performance?

Sensors have been used in buildings since the invention of air conditioning to understand how buildings are performing, from in-room temperature sensors, to sensors on plant equipment, motors, ductwork and pipes. The Internet of Things (IoT) has enabled more sensors of different types to be deployed in more locations throughout the building easier than ever before. The point of installing and using IoT sensors is to gain deeper insight into how buildings are performing, and ensure buildings are healthier, more productive for people to work in, more effective to run and more energy efficient. This article looks at in-room sensors, such as temperature, air quality and occupancy, and how IoT sensors can help improve building performance. The benefits of IoT sensors is that they are easy to install, both physically and from a commissioning perspectiveThe benefits of IoT sensors is that they are easy to install, both physically and from a commissioning perspective. Cabling is usually minimal or not required at all: IoT sensors are battery powered, or require simple USB power (from a plug socket) or utilise Power over Ethernet (PoE). IoT sensors use low power wireless protocols (such as Bluetooth, Mesh etc) to send data, and thus can be placed anywhere within a building and do not require multiple physical IOs for integration. Unprecedented amounts of data IoT sensors are usually cost-effective such that thousands of sensors can be deployed throughout the building without much effort. This gives an unprecedented amount of data to building managers, which comes with its own challenges – How to make use of this data? There are two ways to utilise this data to improve building health, performance and efficiency: Use an effective monitoring platform or data analysis tools to turn raw data into actionable insights. This can provide the building and facilities team with insights to be more pro-active, and spot temperature, air quality, overcrowding, etc issues even before the users or tenants begin to notice e.g. it’s too cold, too drafty, too stuffy, etc. Integrate the live data from the IoT sensors straight into the Building Management System (BMS) and create new control strategies to automate the building further. This requires a bit more integration and commissioning work upfront, but the performance and efficiency benefits through automation will give a fast Return on Investment. The key here isn’t the sensor integration itself, but the building control strategy that will be the logic to which the building automation fucntions. Some use cases of IoT sensors are: Temperature and HVAC A common problem I’ve heard from many buildings is that existing temperature sensors that connect to the BMS have been placed in the ceiling, and not at head height. Using battery powered IoT temperature (and humidity) sensors, and sticking them to the wall at head height, is a quick and easy way to measure temperature where it actually matters.Data can be used to plot temperature heatmaps, find hot or cold spots, or analyse the solar heat gain Data can be used to plot temperature heatmaps, find hot or cold spots (e.g. if two nearby FCUs are working against each other, one heating one cooling); or analyse the solar heat gain, and adjust internal loads. The IoT temperature sensors can be connect to the BMS to provide more accurate temperature data to FCUs instead of the sensors in the ceiling. In general, IoT senors can easily be reconfigured and moved, e.g. during a fit out. But care needs to be taken to keep a close eye on the sensors and which room/space they relate to. Battery will need to be changed every 5 years. The IoT temperature sensors are cheap enough that they can simply be replaced with new ones e.g. the sensors element need recalibrating. Indoor air quality sensors and HVAC Accurate CO2 level sensors (which use duel channel NDIR technology) with IoT connectivity are getting cheaper and can also be used to do ‘heatmapping’, of the building, and provide accurate insights on indoor air quality. Similarly, heatmaps can be done with particulate matter sensors (PM10, PM2.5, PM1), VOC sensors and others embedded in an IoT connected sensor. CO2 level sensors in Accurate CO2 level sensors  with IoT connectivity are getting cheaper and can also be used to do ‘heatmapping’particular are important as the level of CO2 indoors affects our cognitive ability. High indoor CO2 levels hinder our productivity. Indoor CO2 levels of 900ppm to 1400ppm and higher, which are seen in buildings with poor ventilation, reduce our ability to make decisions and use complex information by 15% to 50% and higher, respectively. Indoor CO2 levels are also a good indication of the risk of infection, as people breathing are usually the main source of CO2 in buildings. So being able to monitor CO2 levels in every space inside the building will provide building owners, tenants and users with reassurance with regard to COVID-19 related challenges. ‘eCO2’, a derivative from VOC sensors, should NEVER be used as a measure of CO2 levels. All CO2 sensors elements need to be recalibrated every 3-5 years. Occupancy level and HVAC Knowing the occupancy on every floor of the building can be used to control HVAC systems. Through BMS integration, controlling the flow of ventilation dynamically, based on real-time floor-by-floor occupancy, allows the building to ‘breathe’ with actual demand.Employing an occupancy-based, dynamic control strategy on the BMS reduces the energy consumption for buildings that rarely see full occupancy This balances the building from a technical perspective, and improves air delivery by opening up more ventilation capacity. Employing an occupancy-based, dynamic control strategy on the BMS, not only improves the indoor air quality, but also reduces the energy consumption for buildings that rarely see full occupancy, or have dynamic use (which will only be more common as we begin to work-from-home more often) Measuring the number of people is difficult, which usually means expensive. One way to count people is using PIR sensors places under each desk. This can get expensive for 1,000 desks even if one IoT PIR sensor is relatively cheap. Another way is to use a less accurate, but cheaper method, e.g. using long-range sensors that count the number wireless devices in a vicinity / floor, and using that as a proxy for percentage occupancy levels. Summary 1,000s of IoT sensors can be easily installed anywhere throughout any building. To get the best out of an IoT system a clear use case (or set of use cases) is necessary. By understanding the use cases and benefits, the right design, UI or integration can be used to maximise the cost-benefit ratio for the specific use cases, for example: BMS integration for IoT temperatures sensors; Relevant platform UI and analysis to extract actionable insights for the Facilities Management team from the raw IoT sensor data; or Correct HVAC control and automation strategy based on occupancy level data.

2020 Rewind: Highlighting Sustainability In The Age Of Climate Change
2020 Rewind: Highlighting Sustainability In The Age Of Climate Change

Sustainability and environmental impact are core issues of the HVAC market in 2020 or any year. During the last year, HVACinformed.com has addressed multiple facets of sustainability in some of our most popular articles. This retrospective will highlight some of the sustainability articles published during 2020 at HVACInformed.com. An HVACInformed.com Expert Panel Roundtable commented on various aspects of sustainability, including the responsibility of HVAC manufacturers to develop more sustainable, energy-efficient products that can reduce a building’s reliance on fossil fuels. Energy consumption pattern Honeywell has launched a platform that incorporates newer technology. Combining self-learning algorithms with building automation, Honeywell Forge Energy Optimization is a cloud-based system that analyzes a building’s energy consumption pattern and adjusts its settings. Heat networks, or district heating, are becoming an ever-greater part of the industry’s involvement Pete Mills of Bosch Commercial & Industrial outlines how cities are using ‘heat networks’ to achieve carbon emission targets in the United Kingdom. Heat networks, or district heating, are becoming an ever-greater part of the 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. Centralized heat generator Generally, heat networks are defined as a system of supply pipes with a centralized heat generator (Energy Center) 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. Some U.S. cities are taking the lead to make building performance standards mandatory, thus providing additional incentive for customers to invest in new, more efficient and climate-friendly HVAC technologies. New York City has deployed its Carbon Mobilization Act, which will cut six million tons of CO2 annually by 2020. Washington D.C. adopted the first Building Energy Performance Standard, which will reduce energy use in buildings by more than 20%, thereby lowering carbon dioxide emissions by a million tons annually. Improving environmental performance Newer buildings tend to be designed to be ‘green’, but what about older existing buildings, which still represent the largest share of environmental impact? There is more work to be done in the retrofit sector; and improving environmental performance of older buildings often involves ‘deep retrofits’ that are costly and impact multiple factors inside a building. In the COVID-19 era, there is also growing concern about needs such as circulating outside air, increasing humidity, and improving filtration systems even as older buildings seek to become greener. The consistent theme is a need to work toward better-designed, more energy efficient and healthier buildings The consistent theme is a need to work toward better-designed, more energy efficient and healthier buildings. The California Air Resources Board (CARB) is moving forward with rulemaking that sets limits and deadlines to decrease the use of refrigerants with global warming potential (GWP) in the commercial refrigeration market and in the residential and commercial stationary air conditioning equipment markets. Air conditioning systems California regulations are widely expected to influence the direction of other states seeking to regulate GWP of refrigerants. The addition of biodiesel lowers the carbon content (and thus the environmental impact) of heating oil. The U.S. Environmental Protection Agency says biodiesel reduces greenhouse gas emissions, including nitrogen oxide. The process of making biodiesel from renewable and organic sources also boosts the environmental profile. The Wyss Institute at Harvard University has developed an evaporative cooling system that uses a specially coated ceramic to cool air without adding humidity. Researchers say the approach can yield more affordable and environmentally friendly air conditioning systems for the future.

Honeywell Unveils Honeywell Electronic Air Cleaners With UV Systems And New Line Of IAQ Sensors
Honeywell Unveils Honeywell Electronic Air Cleaners With UV Systems And New Line Of IAQ Sensors

Honeywell has announced expanding its holistic Healthy Buildings Air Quality offering to help improve and measure commercial building indoor air quality (IAQ) with the introduction of Honeywell Electronic Air Cleaners (EACs) with UV Systems and a new line of indoor air quality (IAQ) sensors. Honeywell Electronic Air Cleaners Honeywell EACs with UV help remove impurities from the air as well as provide filtration and disinfection, without significantly impeding air flow. The new IAQ sensors include Honeywell's Particulate Matter Sensor PM 2.5, Total Volatile Organic Compound (TVOC) Sensor and All-in-One IAQ Sensor. Air quality is essential to a healthy building. It can impact occupant health and productivity, energy efficiency and real estate value. The quality of air is affected by the presence of pollutants in the indoor environment that may cause harm. Facilitating cleaner and safer buildings Building owners are looking for ways to create safer, cleaner air to instill occupant confidence" When IAQ is poor, occupants can experience a drop in productivity as well as adverse health effects such as asthma and bronchitis. The concentration of some pollutants can be two to five times higher indoors than typical outdoor concentrations. "More people are paying attention to air quality and the importance of creating healthier environments in the spaces we use for work, school, entertainment and travel," said Manish Sharma, Vice President and Chief Technology Officer, Honeywell Building Technologies, adding "Building owners are looking for ways to create safer, cleaner air to instill occupant confidence as well as attract future commercial tenants." Sensing technology aids in enhancing IAQ Manish added "We're talking to hundreds of customers who are navigating these concerns right now and working with them to update their building systems to better protect occupants. It doesn't always have to be a complicated process of ripping out old equipment and starting from scratch. It can be a straight-forward HVAC upgrade with modifications that address specific concerns and minimize potential side effects.” He further stated, “Sensing technology is an important tool to identify opportunities for adjustments, only when you can measure particles can you properly control them. Adding a system like Honeywell's can improve a building's air quality by filtering particulates and reducing contaminants." Boosting indoor air flow and quality Honeywell EACs use an electric charge to help remove solid and liquid impurities from the air without impeding air flow. The UV System emits ultraviolet light to damage the DNA structure of certain microbes at the cellular level and inactivate various viral, bacterial and fungal organisms – thus providing filtration and disinfection in one system. Ideal for retrofits, property upgrades and new construction alike, Honeywell EACs with UV Systems can be installed inside a commercial HVAC system, without the need to remove old equipment and install a new system entirely. Honeywell EACs can help save energy, while providing a better heat exchange and can pay for itself with the savings. Enhancing IAQ without changing HVAC infrastructure Honeywell IAQ sensors help owners better determine a building's environmental state and air quality status The new Honeywell IAQ sensors help building owners better determine a building's environmental state and air quality status and allow them to take corrective actions through the building management system (BMS) without a need to rip and replace existing sensors. It is possible to add new sensors to existing temperature, humidity and CO2 sensors currently in place within the building or deploy new All-in-one IAQ sensors to cover multiple sensing requirements in one device. Healthy Buildings solutions Honeywell EACs with UV Systems and new IAQ sensors are the latest in a suite of offerings from the company that focus on creating healthier buildings. Honeywell recently announced upgrades to the Pro-Watch and MAXPRO Network Video Recorders and Video Management Systems solutions, which use analytics and artificial intelligence to identify if building occupants are complying with guidelines around social distancing and wearing masks. Honeywell's Healthy Buildings solution help building owners improve the health of their building environments, operate more cleanly and safely, comply with social distancing policies, and help reassure occupants that it is safe to return to the workplace. These Honeywell solutions are part of a comprehensive effort among Honeywell's businesses to come together to quickly develop solutions that are helping important sectors of the global economy recover.

Honeywell Applies Machine Learning To Boost Energy Efficiency Of Buildings
Honeywell Applies Machine Learning To Boost Energy Efficiency Of Buildings

Machine learning provides a tool to lower energy costs in a building, and Honeywell has launched a platform that incorporates the newer technology. Combining self-learning algorithms with building automation, Honeywell Forge Energy Optimization is a cloud-based system that analyzes a building’s energy consumption pattern and adjusts its settings. “We can help building portfolio owners fine-tune their energy expenditures to drive efficiencies and create more sustainable practices,” says David Trice, Vice President and General Manager, Honeywell Connected Buildings. Autonomous building solutions Honeywell says the autonomous, closed-loop building solution may deliver double-digit energy savings while decreasing a building’s carbon footprint. It can be implemented without significant capital expense or changes to a building’s current operational processes. The system autonomously and continually optimizes a building’s internal set points across hundreds of assets every 15 minutes by evaluating whether the HVAC system is running at peak efficiency.  When analyzing when to make an adjustment, the system considers factors such as time of day, weather, occupancy levels and other data points. The system considers factors such as time of day, weather, occupancy levels Honeywell Forge Energy Optimization calculates its decisions 96 times per 24-hour period in every building in a portfolio. Deployment is a simple plug-and-play process with no changes needed to business mechanics. Systems do not need to be rip-and-replaced. Results of the technology The technology has been demonstrated in a pilot at Hamdan Bin Mohammed Smart University in Dubai, United Arab Emirates, achieving an initial 10% energy savings. The pilot achieved the extra savings over and beyond what was achieved earlier in the highly smart, energy-efficient building with fully connected lighting, cooling, building management, power and efficiency control optimized based on real-time occupancy. The pilot also uncovered local control issues with the chiller plant and fresh air handling unit that were not adjusting to set points. “Honeywell Forge [was able] to drive further energy savings beyond our achievable optimization with the techniques we [had],” says Dr. Mansoor Al Awar, HBMSU’s Chancellor. The university is collaborating with Honeywell to support the advancement of artificial intelligence (AI) and machine learning to drive operational efficiencies. Energy consumption in commercial buildings is significant. Buildings and buildings construction combined are responsible for more than 36% of global final energy consumption and nearly 40% of total direct and indirect CO2 emissions, according to the International Energy Agency (IEA). Energy demand in these sectors continues to rise, driven by improved access to energy in developing countries, greater ownership and use of energy-consuming devices, and rapid growth in global buildings’ floor areas. Opportunities for energy saving It is a market where the potential impact of greater efficiencies is huge It is a market where the potential impact of greater efficiencies is huge. Heating, ventilation and air conditioning often presents the largest opportunity for energy savings in a commercial building. “Buildings aren’t static steel and concrete – they are dynamic ecosystems and their energy needs fluctuate based on ever-changing variables like weather and occupancy,” says Trice. “We are evolving building operations far beyond what would be possible even with a robust team of engineers and the rules they code in their building management system.”
