The spread of COVID-19, commonly known as the coronavirus, continues to pick up pace globally and is increasingly a key priority and in view of the growing concern Daikin Applied (UK) Ltd and Daikin Applied Service would like to reassure the customers that they have adopted a risk-minimization approach to ensure minimum disruption to business. Unfortunately, the onset of the Coronavirus has caused many industry implications, this is a brief update on Daikins supply chain, operations and the measures undertaken to ensure the continuation of the business and support to customers. Precautionary measures They have issued their employees with information to take precautionary measures as advised by the government and NHS and will monitor any changes and advise accordingly. As a business, they have implemented further precautions: Business trips to and from Category 1 countries and regions are prohibited until further notice. Travel to other countries should be avoided unless deemed essential and approval given by Senior Management. Meetings where possible to be conducted via video conferencing, Skype, GoTo Meetings etc. Communal areas are being given extra cleaning, e.g. rest rooms, canteens, door handles etc. Staff are being asked to self-isolate in accordance with government guidelines if they have been in direct contact with someone with the virus or travelled to a category 1 country within the last 14 days. Daikin is considering the introduction of temporary smart working arrangements to allow more flexibility and to help reduce risk. Everyone should practice good hygiene to protect against infections. AHU and Chiller orders Currently their factories both in the UK and Italy are working at normal capacity and they are taking steps to ensure this continues. However, it is possible that the current situation will affect business in the coming weeks and they will keep all customers updated if the situation changes. At present, Daikin has not seen any reduction in the level of service they get from their suppliers with this under constant review and their procurement department is in regular contact with the factories and suppliers, checking lead times and supply issues. Daikin Applied Service Remote workers such as their engineering teams have mobile phones and all have access to office servers via their tablets and laptops. As Daikin’s in-field engineers are generally lone workers, they would consider that their contact with the office and other engineers will be limited and, they will continue to monitor the situation. Daikin on site The frequency of virtual visits may increase, and actual visits decrease Clients with chillers capable of supporting the Daikin On Site remote monitoring, and with maintenance contracts already set up to utilize this, will continue to be monitored regularly. To reduce site attendance however, should faults occur where generally a call out may be required, then these faults will be reset (where possible) via the DoS system and monitored accordingly by one of the remote monitoring team. The frequency of virtual visits may increase (and actual visits decrease) should a reduced workforce through self-isolation occur. Monitoring workforce health As well as Daikin’s own locally stored spares they source spares from their factories across Europe, they purchase spare parts and materials across a range of suppliers who will in turn, purchase materials from across the globe. They will continue to monitor the health and wellbeing of the workforce along with the supply chain.

FabricAir® Inc., Lawrenceville, Georgia, the original manufacturer of fabric HVAC duct, is celebrating its 45th anniversary campaign ‘45 Years of Proven Track Record’ this month in North America and throughout its 10 international subsidiaries. The first modern fabric duct was developed and installed in a slaughterhouse in 1974 by FabricAir’s precursor, Denmark-based IPS Dansk Presenning A/S, a company in the Eletrolux Group. The early fabric duct model designs successfully provided a safer environment for employees and more sanitary production lines by preventing condensation accumulation, corrosion and industrial hygienic challenges associated with food processing and conventional metal HVAC duct. Precision Spot Ventilation The research and development department developed innovations such as NozzFlow–plastic nozzles Retitled IPS Ventilation A/S as it spread across Europe in the 1980’s, new models were developed for applications beyond food processing. Soon IPS Ventilation A/S was the pioneer in fabric duct by the 1990’s. The 1990’s helped form the company’s leadership and product innovations that are still staples of ventilation today. Brian Refsgaard, FabricAir’s current CEO, joined the firm as a sales and business development manager. The research and development (R&D) department developed innovations such as NozzFlow–plastic nozzles for precision spot ventilation; Trevira–a cutting-edge permeable and washable fabric woven with flame-retardant materials; and a host of different vent designs to embrace most airflow challenges. Architectural Ceiling Ventilation Market FabricAir made its North American market penetration in 1989, which led the company beyond refrigeration and into many HVAC applications. Retail, office, education and other commercial uses were commonly specified by engineers seeking uniform air dispersion. ‘Make it better and make it easier’ was the motto driving new product developments after 2000 Meanwhile, contractors welcomed its installation labor reduction of up to 60 percent versus conventional round metal ducting in the booming open architectural ceiling ventilation market. ‘Make it better and make it easier’ was the motto driving new product developments after 2000, such as the All-In-One suspension system, a popular product with architects because it aesthetically keeps an inflated appearance whether the air handler is operating or not. Computational Fluid Dynamics After the world recession began in 2009, FabricAir gained an even larger foothold in the ventilation market as value engineering became important in new construction projects. Today, FabricAir is still innovating and expanding. It recently introduced its new R&D AirLab, a computational fluid dynamics (CFD) analysis service, and state-of-the-art enhancements to its laser-cutting technology. Its U.S. operation is one of 11 international subsidiaries that help make it a world leader in fabric air ducting. “We foresee FabricAir growing exponentially another 45 years and beyond, while also remaining a worldwide leader in fabric HVAC duct innovation,” said Brian Refsgaard, CEO, FabricAir.
Annexair unveiled a new line of more sustainable and eco-friendly HVAC systems during AHR Expo in Orlando. The company displayed the new units, made from biosourced engineered composite panels, in a parking lot that was a short drive from the Orange County Convention Center. Composites are 50 to 60% lighter and five times stronger than metal. The engineered composite panels have reinforced glass fiber. Annexair combines the composite panels with green foam insulation made from recycled water bottles and glued together using a non-chemical adhesive resin derived from sugar cane. Performance of the 100% eco-friendly foam surpasses any other type of insulation, says the company. Insulated composite panels are available in 1-in, 2-in, 3-in, 4-in and 5-in thicknesses and take the place of structural steel in Annexair’s new generation of HVAC equipment. There is a lifetime warranty against corrosion and zero leakage. The company claims it is "the most advanced, sustainable and eco-friendly HVAC system on earth.” Eco-Friendly HVAC System “We are making a major transition to modernize the industry and make it more eco-friendly,” said François Lemieux, Annexair President, at a reception during AHR Expo. The biocomposite unit took nine years to develop and is the world’s first of its kind, he says. Manufacturing processes, such as using between 30 and 40 million recycled water bottles, will help to reduce the industry’s carbon footprint.Some 26,500 recycled plastic bottles are used in manufacturing the ERUs Some 26,500 recycled plastic bottles are used in manufacturing the energy recovery units (ERUs), and 18,000 bottles are used to manufacture the makeup air units (MAUs). The systems are built inside a composite housing using motors and other components from other manufacturers. A rooftop unit with a built-in gutter system uses airport-style doors, and there are drain pans and easy walk-in access. There is no welded steel. Panels are seamless, no matter the unit size; panels can be made up to 12-feet wide and 45-feet long in a single piece. "We are making a major transition to modernize the industry and make it more eco-friendly" Easy cleaning and impoved lifespan Smooth rounded interior corners and edges ensure hygiene and no dirt accumulation for easy cleaning. FDA-approved anti-microbial/UV nanotechnology improves casing durability and lifespan for the inside and outside casing, including anti-fungal, chemical resistance, water repellence and anti-scratching.Annexair intends to sell the systems at the same price as comparable traditional systems Annexair intends to sell the systems at the same price as comparable traditional systems to guarantee better access to green technology for the industry. The system is more durable, does not rust and is very light for building structures and transportation. Construction is 50-60% lighter. It also reduces energy loss and is fire-resistant. Composite casings Use of composite casings reduces the greenhouse gas produced by 85 percent. Annexair intends to stop assembling metal-based ventilation units by December of 2021 to meet business sustainability targets. The system is a perfect complement to LEED certification, says Lemieux. The systems will be manufactured in a new 300,000-sq ft factory, 70 miles east of Montreal, Canada, that is automated and eco-friendly. Annexair seeks to be carbon-neutral by 2024-25.
There was plenty to see and appreciate at AHR Expo in Orlando. And there is good news to report: Innovation is alive and well in the HVAC market. Some new products on display demonstrated genuine ingenuity. Exhibitors had enthusiasm to spare as they shared what’s new in the market with this first-time visitor to the show. HVAC is not a new market, but it is changing and, in some regards, re-inventing itself. The vibrancy, variety and sheer size of AHR Expo showed off the newest and best the industry has to offer. ‘Better Way to Heat and Cool’ Electronics highlighted the benefits of inverter systems -- "a better way to heat and cool" -- at their press event at AHR Expo. Despite the advantages, HVAC contractors are pushing back at the new, less familiar systems. The industry is at a "crossroads." Inverter systems have variable-frequency drives that control the speed of the compressor motor, enabling lower power consumption – operating at a partial load as Innovation is alive and well in the HVAC marketLG opposed to a full load. For example, an inverter system may use only 20 amps compared to 90 amps for traditional systems. The systems are quieter, too. There are also now inverter systems for ducted systems – "the space in between that nobody is talking about". New "hydro kits" can also extend the benefits of the systems, providing radiant floor heat or the ability to melt snow from a driveway. LG Electronics also introduced a new line of IP-based controls, aimed at the 97% of commercial buildings that are 100,000 square feet or less, many of which don't have building automation systems. The controller can be used in lieu of integrating with third party systems, which can add costs. They also are introducing predictive analytics that can consider multiple conditions over time and then predict things that may happen, such as maintenance requirements. The company also emphasized the benefit of LG as part of a range of products the company provides for the home, from OLED televisions to appliances to robotic vacuum cleaners. There is an opportunity for all the devices to be connected to an LG panel and "drive the experience." Monitoring Indoor Air Quality Airthings was a new exhibitor at AHR Expo, located off the beaten path among the high-numbered booths. Even so, the company had a great show with “enormous interest,” said Oyvind Birkenes, CEO. Airthings has an indoor air quality monitoring system, with a battery-operated, wireless sensor as the main component. There Some new products on display demonstrated genuine ingenuityare actually seven sensors inside the device, monitoring radon gas, CO2 level, temperature, humidity, VOC levels, pressure and ambient light. The device can be easily mounted on the wall and provides data every 5 minutes, which is sent to the cloud to be analyzed. The cloud system provides an overview of data, which is customizable. Users can set notification levels and/or download air quality reports. The system can also be integrated with building management systems (BMS) or other dashboard displays. A hub can manage up to 50 of the sensors for larger systems, in effect, a fully independent local network. Birkenes said the device provides a “disruptive” upsell opportunity for various platforms. Cooling Towers Making a Comeback A new era of cooling towers includes products that are modular and built on a smaller scale for tighter locations, says Neal Walsh, HVAC Business Manager, Baltimore Aircoil Company. “We’re turning the concept of cooling towers on its head,” said Walsh. The new concept leverages the energy efficiency advantages of cooling towers, while opening new applications to the technology. The modules of the product can be put in place by a forklift, and it is less than half the size of a traditional cooling tower. Up to six of the devices can be installed in A new era of cooling towers includes products that are modular and built on a smaller scale for tighter locationsa row with a control panel. Low water usage enables the system to be flushed and refilled once a day – no expensive water treatment needed. In all, it is less expensive to install and maintain, and could be installed inside a building, on a roof or anywhere there is space. The product is popular with school districts, which seek to avoid refrigerants. The new design is driving a “resurgence in popularity” in the market, said Walsh. Plastic Pipes with Easy Waterproof Sealing Uponor displayed pipe systems made of PEXA (cross-linked polyethylene) plastic, featuring “crosslinking thermal memory.” The pipe returns to its original shape when heated. It is available in ½-in. to 4-in diameters for residential or commercial installations. A special tool can be used to expand the pipe to accept a fitting, and then the pipe returns to its original shape when heated to create a water-tight seal without glue or solvents. The pipes can be used for radiant heating applications, and Uponor offers “roll-out” mats (pre-assembled configurations of pipes) for easy installation. Through a partnership with a Serbian company, the company also now offers polypropylene pipe for larger applications. There was plenty to see and appreciate at AHR Expo in Orlando SPVU Systems with Greater Efficiency Bard offers “single-package vertical units” for commercial applications in space-confined systems, whether the application is equipment cooling or “creature Many products demonstrated at AHR are also big in the education marketcomfort,” said Paul Quigley, Senior Vice President, Sales and Marketing. The factory-sealed systems ensure greater durability for mission-critical applications, such as telecommunications, data centers, etc. Bard’s products are also big in the education market (especially portable classrooms). Their line has been completely redesigned and reconfigured by Bard’s engineers; they have replaced nine major product families (and 10 million product iterations) with just two categories. The new models meet the Department of Energy’s 11EER minimum energy conservation standards for Single Package Vertical Unit (SPVU) air conditioners and heat pumps – a 22 percent increase in efficiency. They can also remove 35% more humidity than other units. The new systems use recycled denim for insulation (instead of fiberglass). Leveraging the Benefits of UV-C UV Resources highlighted the use of UV-C spectrum light for HVAC applications. They have a germicidal lamp system that uses UV-C to penetrate the HVAC coil to eliminate microbial buildup. It keeps coil surfaces, drain pans, air filters and ducts free of organic buildup and works better than pressure washing or chemical treatment. The company also displayed a germicidal UV fixture that can be wall-mounted at 7 feet or higher in a room. Special louvers direct “germicidal irradiation” at an upward and outward angle and create a zone of UV-C to kill germs and minimizes the dosage in the lower area of the room. It's useful in doctors’ offices, public buildings, etc. LG Components’ New Compressor LG Components launched a new product – a fusion compressor (hybrid) that merges the best of rotary systems and of scroll technology. Durability-improving innovations include a more sensitive vacuum prevention device and a stronger, stress-tested discharge reed valve that withstands the harsh operating conditions posed by refrigeration applications and limits excessive sound levels. It is compatible with multiple refrigerants, including R-404A, R-507, R-407A, R-407C, R-448A and R-449A; the compressor has a capacity range of 1-6 HP Catch up on our Day One Review here. or our Day Two Review here.
What is the cost of “rolling a truck” to service an HVAC system, and how can you maximize the efficiency of such a call while minimizing the cost? On the second day of AHR Expo in Orlando, several companies mentioned the benefits of various diagnostic and analytics systems that can be accessed remotely and that provide information for a technician about the nature of a problem, and what parts are needed, before he or she leaves for the call. It’s an example of how technology can make life easier for HVAC companies. Technology can help HVAC companies in other ways, too. For example, AHR Expo exhibitor Jobber offers software to help small businesses, including HVAC companies, to be more successful. The company focuses on providing software for various home and field services industries — there are more than 50 of them in all. The software is designed for any small- to medium-sized company, from a sole proprietor up to a company with 50 employees. The cloud-based software as a service (SaaS) offering can be accessed through a web app or a mobile phone. Implementing Technology Several companies mentioned the benefits of various diagnostic and analytics systems that can be accessed remotely and that provide informationWhen a service request is received, whether by phone or over the internet, the Jobber software “takes over” and guides the process through quoting to scheduling to dispatching crews to invoicing and collecting payment. "The HVAC market is in the early adopter stage for implementing the technology, and demand is increasing", says Shawn Cadeau, Jobber’s Chief Revenue Officer. Jobber currently focuses on the North American market and is available in English only. Monthly fees start at $29, and a larger system might cost up to $249 per month. Some of the equipment on display at AHR Expo is also designed with contractors in mind. Rheem is announcing more models in its Renaissance line of light commercial products designed to be installed on the Carrier footprint. The equipment is designed for the contractor. Rheem brings contractors into the design process, so the “service mentality” that helps contractors do their jobs is included in the design. Minimizing Energy Consumption Heat Transfer Products Group (HTPG), the refrigeration business of Rheem, is showing off their EcoNet-enabled controller that minimizes energy consumption in critical cooling applications by monitoring the compressor to eliminate excessive runtime. One trend is away from mechanical components and toward more One trend is away from mechanical components and toward more electronicselectronics. For example, an electronic expansion valve provides more control and eliminates the need for mechanical thermal expansion valves.“People are excited about electronic control solutions,” said Raleigh Thompson, HTPG Marketing Manager. For medium and large-size systems, HTPG will launch new platforms in April, in anticipation of new Department of Energy efficiency standards. Daikin announced the Rebel Applied Packaged Rooftop System that combines high performance and a compact, configurable footprint. It features a casing design for ultra-low air leakage, which can save thousands per year, and Copeland ZPKZ scroll compressors. Reducing Costs and Staying Ahead Emerson makes the compressors, designed for superior part load efficiency and to reduce customer costs. Technology innovations of the compressor include a new hermetic motor, a scroll discharging value to optimize performance and oil-injection to mitigate heat. The Daikin Rebel system far exceeds minimum efficiency requirements through 2023. Emerson also highlighted the Sensi smart thermostat, the Multiple Thermostat Manager for property-wide comfort control, and the Sensi Predict 10-sensor system that analyzes the HVAC and displays how the system is performing so technicians can stay ahead before failure occurs. Detailed monthly performance summaries are provided, and real-time alerts are generated in the event of system of decline or failure — more information to help HVAC contractors.

When Pine Valley Ranch, a Spencerville, Ohio-based egg-breaking facility was looking for an energy efficient way to wash 600 cases of eggs an hour they turned to Consolidated Hunter, a local heating contractor, and Pickrel Brothers, a provider of industrial heating supplies to help present options. Their recommendation? Install six Weil-McLain SlimFit 750 commercial high-efficiency hot water boilers. “We’re an egg-breaking plant,” explains Evan Fleck, an owner of Pine Valley Ranch. “Our eggs come straight from the barn and are immediately washed. Then they are broken, separated and chilled. Once this is done, they are loaded into liquid tankers and shipped to be pasteurized. Every step of the process is important, especially the washing of the eggs. We need plenty of hot water for that, as well as for other daily operations.” Efficient production process The 4.5 million BTU/hour Pine Valley heating system supports seven individual heating zones The 4.5 million BTU/hour Pine Valley heating system supports seven individual heating zones. The first three zones are dedicated to the egg washing machines and supported with 750 BTU/hour boilers. The fourth and fifth zones support the clean-in-place equipment (990,000 BTU/hour heat exchangers) while the two remaining zones are for the indirect fired water heater and the on-site plant mixing station. “Every zone is critical to ensuring a high-quality, efficient production process,” says Fleck. “We have more than 900,000 chickens at this facility and they produce a lot of eggs. The Weil-McLain boiler systems provides a consistent source of hot water to accommodate this large number.” Wide range of commercial installations SlimFit boilers have been serving the heating industry since 2009 with rugged, cast horizontal heat exchanger sections that provide thermal efficiencies up to 95.8% (SlimFit 1000 & 1500 models). The boilers feature a low pressure drop design, with large water passageways to accommodate a wide range of commercial installations, including retrofit and replacement applications with older water systems. Other standard features include a composite condensate tray for heat exchanger longevity The larger SlimFit 1000-2000 models feature a narrow ‘door-fit’ profile and integrated roller casters for improved installation maneuverability in confined spaces and weight restricted areas, saving contractors time and money. Other standard features include a composite condensate tray for heat exchanger longevity, customizable control mounting location (front or side) and leveling legs, which mitigate the need for a concrete service pad. Typical heating operation conditions Control features include a setup wizard that guides the installer through the start-up process and 10 preset typical heating operation conditions. The SlimFit also features zone stacking up to 24 programmable zones without the need for additional external panels and 0-10 VDC analog output signal for easy integration with a lag boiler in a hybrid system. “We really appreciate how the Weil-McLain boiler-system enhances our operation,” says Fleck. “The equipment was installed when the facility was built so they’ve been part of our production process from the beginning. Running a plant of this size always presents challenges, but our hot water needs are not one of them.”
An innovative, efficient air conditioning system has been chosen to provide cooling and comfort to guests at the Strand Palace Hotel in the heart of London. The hotel, which is walking distance from some of London’s most famous theatres and has been welcoming guests since 1909, needed to modernize its heating and cooling systems to ensure a quality experience for guests. High levels of energy efficiency and minimal disruption to the hotel’s operation during installation were also key considerations. Hybrid VRF system The solution came in the form of the unique Hybrid VRF (Variable Refrigerant Flow) system from Mitsubishi Electric, which offers simultaneous heating and cooling with full heat recovery. The combination of refrigerant and water used in Hybrid VRF also delivers a much lower Global Warming Potential (GWP) than traditional VRF systems and saves around 30-40% in refrigerant use in comparison. The fit-out was designed by Elementa Consulting and installed by Working Environments and has seen units fitted across the hotel’s 790 rooms. The project started in September 2018 and is due for completion in April 2020, making the project the biggest of its kind in Europe. With an occupancy of 96% every day of the year, it was crucial that the hotel remained fully operational during installation to minimize loss of revenue and disruption to guests. Refrigerant is only used between the outdoor condenser and a special Hybrid Branch Controller box Cost-saving benefits Ted Connell, specifier and designer at Elementa said, “Many different systems were assessed, but the expertise of the Working Environment team combined with the modular installation of the Hybrid VRF made it stand out as the right option for The Strand." "It was possible to complete the installation floor by floor, even half a floor at a time where necessary, allowing the hotel to remain open during the process.” The Hybrid VRF system also offers additional cost-saving benefits by removing the need for leak detection equipment. Refrigerant is only used between the outdoor condenser and a special Hybrid Branch Controller box (HBC). From here, water is used to transfer heating or cooling to each room, removing the need for additional equipment or additional annual maintenance regimes.
A new multi-million pound MRI scanner facility at NHS University Hospital of Wales, Cardiff, is being cooled by high-efficiency chillers from Carrier. Carrier’s heating, ventilating and air conditioning (HVAC) business is a part of Carrier, a global provider of innovative HVAC, refrigeration, fire, security and building automation technologies. Three Carrier AquaSnap 30 RBP air-cooled liquid chillers have been installed by mechanical and electrical contractor Whitehead Building Services for the project’s main contractor Kier, under the Designed for Life construction procurement and delivery frameworks set by the Welsh National Health Service. Greenspeed intelligence The chillers deliver a combined cooling capacity of 900kW, and provide the stable, reliable cooling required to maintain the high-tech diagnostic equipment in peak condition. Chilled water is supplied to the scanners at six degrees Celsius and returned at 12 degrees Celsius, to begin the cooling cycle again. Equipped with Carrier’s Greenspeed intelligence, the chillers have variable-speed water pumps and condenser fans to precisely match cooling output to current load conditions. This enables the system to operate with outstanding part-load efficiency, ensuring low carbon emissions and reduced running costs over the life-time of the plant. The new scanning facility provides an important diagnostic and therapeutic service to the hospital" “These units offer exceptional resilience as they have three separate refrigerant circuits, and are therefore ideal for use in such critical applications,” said Russ Tyrrell, senior sales engineer for Carrier. “In the unlikely event of one circuit going out of operation, the chiller can continue to operate and deliver up to 66% of cooling capacity, maintaining a high level of cooling.” Enviroshield coil coating Variable speed fans also deliver low noise, an important consideration given the hospital application, plus extended operational life due to reduced wear and tear on compressors, fan motors and other moving mechanical parts. “The new scanning facility provides an important diagnostic and therapeutic service to the hospital, and it is vital the machines are kept operational,” said Martyn Brown, who led the project for Whitehead Building Services. “We selected Carrier chillers because of their reliability and the fact it is proven technology. There are three existing Carrier chillers in use at the hospital, and they have an established track-record.” To safeguard the units from corrosion in the challenging coastal environment, condensing coils are protected by Carrier’s Enviroshield coil coating. This factory-applied flexible epoxy coating completely encapsulates and isolates the aluminum metal of heat exchangers from the surrounding environment.
A construction project in Calgary, Canada, called Cube, features several firsts. It’s the city’s first office-to-residential space conversion and real estate developer Strategic Group’s first re-purposing project. It’s also the first building in Canada to feature the latest advancement in condensing boiler heating technology from Weil-McLain. The Cube – a 52,000 square-foot, seven-story building in Calgary’s Beltline neighborhood –features 65 one and two bedroom residential rental units and is just a short walk from the city’s downtown area. Once the aging Stephenson office building, the 38-year-old building was converted to new residential and rental units in 2019. Latest Boiler Technology Cities like Calgary have seen office building vacancy rates as high as 27% in the past few years" The building’s developer, Ash Mahmoud, Managing Director of Calgary-based Strategic Builders Inc (SBI), the construction arm of Strategic Group, which owns, manages and develops office, retail and apartment properties across Canada, oversaw the conversion project. “Cities like Calgary have seen office building vacancy rates as high as 27% in the past few years,” said Mahmoud. “Rather than let downtown buildings go unused, it has been one of our core missions to convert them into residential.” In addition to incorporating contemporary designs and styling finishes, Mahmoud also sought the latest in boiler technology to heat the new development. High Efficiency Boiler System To conduct the HVAC overhaul, Mahmoud turned to Nu-Mun Contracting, a Calgary-based HVAC company offering commercial and residential plumbing, heating, and air-conditioning services. Working with SBI and the project engineer, David Muncaster, owner of Nu-Mun Contracting, devised a strategy to convert the building to a high efficiency boiler system and recommended specification of the latest advancement in condensing boiler technology: the Stainless Vertical Firetube (SVF) from Weil-McLain. Eric Cameron, project manager with Nu-Mun Contracting, oversaw the boiler installation at the building. “We have a long standing relationship with Weil-McLain, and we trust the quality of their boilers,” said Cameron. “The SVF boilers were the perfect match for the space.” Simplify Installation And Operation The SVF also meets all market-driven bid specifications, and is designed for most heating needsTo meet the building’s heating style and load, the team installed two SVF 1100 MBH high-efficiency condensing gas boilers in the building. The SVF boilers features thermal efficiencies up to 97.1%, a clover-shaped stainless steel fire tube heat exchanger for corrosion resistance, and the intuitive and user-friendly Unity™ control system to simplify installation and operation. “With superior thermal efficiencies, the SVF line offers cost savings and energy efficiencies that could allow owners to qualify for local utility rebates, if available,” said Craig Demaray, National Sales Manager with Weil-McLain Canada. “The SVF also meets all market-driven bid specifications, and is designed for most heating needs including applications in schools and other educational facilities, public institutions, healthcare buildings, offices, hotels, multi-family, churches and more.” Multiple Boiler System The high-water content design of SVF heat exchanger means a low loss header is not required providing cost savings so the boilers can simply be piped in a primary-secondary design. The on-board Unity™ control system allowed the boilers to communicate with each other in a Multiple Boiler System (MBS). A master boiler controls the modulation and sequencing of the boilers on the network In this configuration, a master boiler controls the modulation and sequencing of the boilers on the network to achieve the desired system supply temperature. “With the automatic sequencing feature, the boilers communicate directly with one another so they sequence themselves and rotate as needed,” said Cameron. “They operate to optimize energy use and efficiencies. When heat is required, the boilers will stage on as needed.” Time-Saving Installation The Cube conversion project was completed in 12 months and more than two-thirds of the building is already leased to residents. Mahmoud praised the experience with Nu-Mun Contracting. “Working together with Nu-Mun was a seamless operation,” said Mahmoud. “It was a really great relationship and, as a result, the job was a complete success.” The start-up and installation progressed smoothly in part due to the way these boilers are designed" “The start-up and installation progressed smoothly in part due to the way these boilers are designed,” said Cameron. “The SVF boilers offers time-saving installation features that include heavy-duty roller casters for improved maneuverability in confined spaces, industrial-grade leveling legs, and an end-shot burner design requiring only 18 inches overhead space.” Low Operating Costs Mahmoud appreciates the ease of maintenance that the boilers offer for the building staff “The boilers are really user friendly,” said Mahmoud. “We can even conduct the annual maintenance on the units ourselves to keep them in tip-top shape.” In addition to offering class leading serviceability, the new boilers also offer low operating costs and are expected to bring energy savings and a reduction in gas usage to the facility. But most important, Mahmoud reported that tenants are extremely pleased with the climate and comfort of the building.
Indoor comfort technologies from LG Electronics spotlighted at the 2020 AHR Expo, helped transform a 1920s art-deco office building into a brand-new luxury boutique hotel. The Sinclair, a Marriott Autograph Collection Hotel, is featured in a new case study debuting at the 2020 AHR Expo show (booth No. 6343). Future-Ready Technologies The Sinclair Hotel aims to create an unforgettable and luxurious experience for its guests in a classic 1929 building in downtown Fort Worth, Texas. The hotel’s owner and management team sought state-of-the-art technology to power, sustain and manage the entire property while maintaining the historic building’s unique design and architectural details. The Sinclair Hotel required individual control of its HVAC system throughout 164 guestrooms The hotel required individual control of its HVAC system throughout 164 guestrooms (featuring 50 different room types) and sufficient heating and cooling for the lobby bar, reception area and large basement restaurant. With this in mind, the hotel management team identified LG as a company that was not only able to fulfill a myriad HVAC needs, but also create a full building ecosystem with its range of cutting-edge technologies across an expansive portfolio. Powerful Air Conditioning Technologies In the hotel’s quest to be low-voltage, the management team has employed what is believed to be one of the world’s first applications of Power-Over-Ethernet (PoE) to a large array of end points, to help achieve many of energy-efficiency and forward-thinking goals for the Sinclair’s desired level of technological ability. With PoE installed throughout the property, a variety of LG’s award-winning products will provide a low-voltage and energy-efficient solution for this forward-thinking partner. LG’s award-winning Multi V IV Heat Recovery Units were selected for their ability to provide individual room comfort for each space within the larger property. The Multi V IV also contributes to the building’s energy efficiency, high performance and flexibility in design and installation options. Installation versatility was considered to a key factor as the historic building was restricted in regard to lower ceilings as well as limited space for out-door equipment. AC Smart controller Local HVAC and Variable Refrigerant Flow (VRF) experts, Texas Air Systems, recommend the installation of a variety of indoor solutions that ensure a quiet conditioned space, including LG’s Art Cool Mirror and Ceiling Cassettes, to accommodate the tight ceiling area within guest rooms. The unit’s quiet operation supports a tranquil guest room environment and contributed to the decision behind their selection for this property. The technology works unnoticed, contributing to the comfort and experience of a guest’s stay. LG’s AC Smart controller allowed for seamless handling of the HVAC system for the management team. This innovative control solution for a variety of applications offers a single LG platform that drives both variable-refrigerant-flow technology and energy efficiency. Property managers can now easily manage set and monitor the building’s heating and cooling performance with ease. Variable Refrigerant Flow (VRF) technology The LG connected outdoor units with slim, space-saving features were installed on the exterior of the building Prior to installing LG’s Variable Refrigerant Flow (VRF) technology, the building relied on an old chiller system to condition the entire building. The old chiller required a great deal of space in the building’s lower level. After switching to VRF, the hotel was able to gain a great deal of usable floor space for the large lower level restaurant. In turn, the LG connected outdoor units with slim, space-saving features were installed on the exterior of the building. LG has created industry-leading VRF technology to minimizes efficiency losses, provide sustainable energy savings and offer some of the lowest life cycle costs of any system on the market today. For similar costs as a traditional system, The Sinclair now has a highly reliable, energy-efficient HVAC solution that delivers comfort and convenience for its occupants.

High efficiency AC technologies Donald adds, “Aligning with a partner like The Sinclair on our shared goals to power the building of the future, allowed an ecosystem that connects our industry-leading air conditioning technologies and other LG products to create a comfortable, elevated experience for guests across the entire property.”
The University of Texas at Austin first opened its doors in 1883 with eight professors, 221 students and a goal of creating quality higher education in the state of Texas. Throughout the last 135 plus years, UT Austin has grown to over 3,000 professors, 51,000 students and has garnered an impressive global reputation. Regardless of growth, the university takes pride in its active attention to pursuing sustainable energy solutions. In the interest of reducing the impact the university has on the local grid and environment, the Carl J. Eckhardt Combined Heating and Power Complex was built to provide energy for the campus. Energy Production Efficiency The system uses the same amount of fuel today as in 1976 with double the amount of served space This power plant has achieved an efficiency of more than 85%, meaning very little energy is lost in the form of heat. This is more than twice the efficiency of a typical power plant. With all of the advancements in efficiency, the system uses the same amount of fuel today as in 1976 with double the amount of served space. Because the energy production efficiency is more than 85%, annual savings opportunities are now on the demand side. In 2010, the Energy Management & Optimization (EMO) team at University of Texas at Austin began a 20-year plan to reduce the average energy use intensity (EUI) on the main campus by 20%. The goal was met early in 2018, so a new goal was set for at least 2% annually. This reduction in energy consumption has been taking place even while the university continues to grow. Achieving Higher Levels Of Sustainability Through initiatives, such as replacing halogen lamps with LEDs in the Texas Memorial Museum and behavioral programs encouraging students to turn off lights, UT Austin has been consistently meeting their goal of optimizing energy consumption. This allows UT Austin to reduce operating costs and achieve higher levels of sustainability. With UT Austin’s continuous growth comes an ever-evolving need for facilities With UT Austin’s continuous growth comes an ever-evolving need for facilities. Recently, UT Austin converted an old technology incubator facility with dense equipment cooling loads, known as the West Pickle Research Center, into new office spaces for faculty. Because the offices do not require as much cooling as the lab, the two constant-speed, oil-lubricated, centrifugal chillers that had previously supported the building were no longer appropriate. There was a 650 ton (2,285 kW) chiller that provided too much cooling, and a 200 ton (703 kW) unit that did not provide enough. Highly Efficient And Optimized Solution The chillers were installed in 1983 and ran on R-11, an ozone depleting refrigerant that is now banned for use in new equipment via Montreal Protocol. The chillers were past due for an upgrade and operating them wasted a lot of energy. Johnson Controls offered a highly efficient and optimized solution with a 300 ton (1,055 kW) YORK® YZ Magnetic Bearing Centrifugal Chiller. Installed in 2018, the chiller provided a perfect middle ground between the two previous chillers and was fondly nicknamed the ‘Goldilocks Chiller’ because it was just the right size for the new building load. With the flexible control options that the variable speed drive offers to meet a shifting building load, unnecessary energy consumption was curbed. Additionally, the magnetic bearing technology in the YORK® YZ dramatically increases reliability, decreases downtime and decreases the need for maintenance. Low Tower Water Temperatures The high efficiency of the YZ makes an appreciable difference in energy costs The UT Austin EMO Team appreciates the independence of the YZ chiller, saying, “We never have to worry about changing filters or checking oil levels, which allows us to focus our energy on saving initiatives rather than the upkeep of equipment.” While operating the YZ Chiller, UT Austin realized an estimated 330,000 kWh or $23,000 annual savings. The high efficiency of the YZ makes an appreciable difference in energy costs over the year compared to the old chillers previously in the building. One of the reasons the YZ chiller can save energy throughout the year is its ability to run at exceptionally low tower water temperatures, thanks to its wide operating map. Reducing Energy Consumption “We used to have to hold the entering condenser water temperature at 65°F (18.3°C) to run our chillers during the winter months, but the YZ Chiller is able to take advantage of our entering condenser water temperatures down to 45°F (7.2°C), greatly reducing the energy consumption.” The YZ is designed for real-world efficiency and operates efficiently at off-design conditions Utilizing magnetic bearings eliminates minimum speeds and lubrication systems that previously limited chillers from operating at extra low lift conditions. The YZ is designed for real-world efficiency and operates efficiently at off-design conditions, which is where chillers operate 98% of the time. Even in a warmer climate like Austin, Texas, there are still plenty of hours where the temperature is cool enough to take advantage of lower entering condenser water temperature. Sophisticated Building Technology While the chiller has been operating, exceptional efficiencies as low as 0.15 kW/ton (23 COP) have been observed. An impressive feature of the YORK® YZ Chiller is its ability to easily integrate into any building setting and run efficiently. In this retrofit to an old lab facility, an immediate efficiency improvement of 15% over UT Austin’s other fully optimized plants was noted soon after starting up the YZ Chiller. Juan Ontiveros concludes, “It can support anyone in any system of any age. You don’t need the most sophisticated building technology to run the YZ and realize awesome efficiencies!”
