Johnson Controls releases the U.S. results of its 2019 Global Energy Efficiency Indicator survey. The study found that 75 percent of surveyed organizations plan to increase their investment in energy efficiency, renewable energy and smart building technology, a 16 percent increase over 2018. The research suggests that sustainability is a key contributor to this increase - 80 percent of organizations with energy or greenhouse gas reduction goals plan to increase investment next year, versus 37 percent without goals. Investing in smart, sustainable building technologies “This is the largest annual increase in planned investment in over a decade,” said Clay Nesler, vice president of global sustainability and regulatory affairs, Johnson Controls. “Investment in smart and sustainable building technologies not only addresses urgent climate challenges but also improves comfort, health, safety and affordability for building occupants and communities.” The study, now in its 13th edition, surveyed 400 energy and facility management executives in the United States to understand current and planned investments, key drivers, and technology trends supporting smart, safe and sustainable buildings. Enhancing energy security Over half of participants believe that reducing energy costs, increasing energy security and reducing greenhouse gas emissions are critical factors to consider when making investments. In addition to these drivers, 87 percent of organizations indicated that resilience is very or extremely important when considering future energy and building infrastructure investments, compared with 68 percent the previous year. The survey also indicates a rising trend towards green and zero carbon buildings Traditional energy efficiency measures top the list of future investments with over two-thirds planning to invest in energy education programs, HVAC equipment and building controls improvements. Despite the common perception that building owners typically run building systems to failure, 42 percent of organizations updated building controls and 36 percent replaced HVAC equipment before end-of-life last year. The survey also indicates a rising trend towards green and zero carbon buildings that are energy efficient and cost saving. The 2019 Global Energy Efficiency Indicator survey results show: 85 percent of organizations plan to have at least one certified green building compared with 72 percent last year, while 62 percent are willing to pay a premium for space in a certified green building. 63 percent of organizations say they are very or extremely likely to have one or more facilities that are nearly or net zero energy or carbon in the next ten years, up from 58 percent in the previous year. 61 percent of organizations surveyed invested in on-site renewable energy in 2019, while 34 percent of organizations invested in the replacement of fossil fuel heating equipment with heat pump technology last year. Furthermore, the report states that there was continued strong interest and investment in smart buildings last year, including - 71 percent of organizations invested in building control system improvements and over half have implemented an enterprise-wide building management system. Over half of organizations invested in the integration of security, fire/life safety systems and lighting systems with other building technology systems last year, with another third investing in energy information management software.

There is a gap between how buildings are designed and how they operate. For one thing, designers may not be focused on operability during the design process. Secondly, technology is playing a greater role in more complex buildings today, but it may not perform to expectations. These were among the observations by Darryl K. Boyce, P.Eng. ASHRAE’s 2019-2020 President, at a luncheon address at the 2019 Annual Conference. Importance of data security “Technology is not evil,” Boyce said. “We can have unrealistic expectations, and technology can be misused.” Additionally, technology can provide a large amount of data/information that can be overwhelming to control technicians. “Operators are being overwhelmed,” said Boyce. “Generally, they do not have the skills to operate today’s buildings and are not properly trained. At building turnover, operators are rarely properly oriented.” Green buildings When green buildings do not operate as intended, the result is ‘performance slippage’When green buildings do not operate as intended, the result is ‘performance slippage’ – the energy consumption is much higher than modeled targets. This can be because buildings were designed with systems that are beyond the capacity of building managers to operate. It could be that systems are complex and require several years to refine and understand. Finally, there is a correlation between performance and level of commissioning. One solution Boyce suggests is to include a building operations team representative throughout the design process. “The design should reflect the capabilities of the people operating the building,” says Boyce. “As a result, we will not be leaving operators wondering ‘How do I make this work?’” An effective turnover and orientation training process are critical. Building automation Boyce said ASHRAE should work with building owner-operator organizations to develop strategies to prepare the operators to effectively operate the building through enhanced training and effective use of building automation and analytical and other operational tools. “We should also engage with building operators at the Chapter and Society level to improve our understanding of their problems and develop educational and training programs to reduce the gap between design, construction and operations,” Boyce said. Facilities management “Facilities management must adopt technology more quickly and far more deeply,” he added. “It must move beyond technology to monitor space utilization and energy consumption. And we need to focus on using technology, data and analytics to enhance the workplace experience.” ASHARE is the American Society of Heating, Refrigerating and Air-Conditioning Engineers, a professional association seeking to advance HVAC&R systems design and construction. It has more than 57,000 members in 132 countries. ‘Building for People & Performance - Operational Excellence’ The theme focuses on overcoming the challenges associated with the efficient operationDuring his inaugural presidential address, Boyce announced the Society theme will be ‘Building for People & Performance - Achieving Operational Excellence’. The theme focuses on overcoming the challenges associated with the efficient operation and performance of buildings. “People must succeed within the buildings we create,” says Boyce. “ASHRAE is committed to preparing building professionals through learning opportunities, engagement and adopting better practices. These are the steps needed to achieve effective operational performance and operator experience.” Boyce is special advisor to the vice-president (Finance and Administration) at Carleton University in Ottawa, Ontario, Canada.
A key deadline for phasing out hydrochlorofluorocarbons (HCFCs) from residential air conditioning systems is less than a year away. Jan. 1, 2020, is the deadline after which there will be no U.S. production or import of HCFC-142b and HCFC-22 (also called R-22). The deadline is part of an incremental phazeout of HCFC consumption and production based on the U.S. commitment in the 1997 Montreal Protocol aimed at protecting stratospheric ozone. Section 605 of the Clean Air Act establishes phazeout targets for the chemicals. The phazeout will be complete in 2030, after which time there will be no production or import of any HCFCs. HCFC-142b retrofit refrigerant HCFC-142b is used in small quantities in refrigerant blends and as a retrofit refrigerant in motor vehicle ACs HCFC-142b is used in small quantities in refrigerant blends and as a retrofit refrigerant in motor vehicle air conditioners that previously used chloroflurococarbons (CFCs), which were eliminated in the mid-1990s for their potential to deplete the ozone layer. HCFC-22 is the most commonly used refrigerant in applications such as unitary air conditioners, cold storage, retail food refrigeration equipment, chillers and industrial process refrigeration. Any air conditioner or heat pump manufactured before 2010 likely uses HCFC-22 refrigerant. Hydrochlorofluorocarbons in air conditioning systems On Jan. 1, 2020, U.S. production or import of HCFC-22 and HCFC-142b will not be permitted in the United States. After this happens, only recycled/reclaimed or stockpiled quantities of HCFC-22 and HCFC-142b will be available for servicing existing equipment, and they will likely be more expensive. These substances have been in the process of being phazed out since 2015, when supplies were reduced by 90 percent. Since 2010, HCFC-22 and HCFC-142b have been available exclusively for use to service existing equipment. There are several non-ozone-depleting alternatives to HCFC-22. They include R-134a and R-410A, which can be used in a new installation; and R-407C and R-407A, which can be used in a new or a retrofit installation. The most common alternative is R-410A, which is manufactured and sold under various trade names such as GENTRON AZ-20, SUVA 410A, and PURON. Significant New Alternatives Policy SNAP (Significant New Alternatives Policy) was established by the U.S. Clean Air Act to identify and evaluate substitutes for ozone-depleting substances. The program looks at overall risks to human health and the environment of existing and new substitutes, publishes lists and promotes the use of acceptable substances, and provides the public with information. EPA reviews alternative refrigerants and maintains a list of acceptable substitutes for household and light commercial air conditioning. For the last 25 years, the air conditioning and refrigeration industry has been working to reduce its use of CFC refrigerants, which are no longer available on new equipment. The industry has used alternative refrigerants and achieved higher efficiency ratings to achieve the goals. CFC refrigerants Long life of AC equipment has extended the continuing use of CFC refrigerants by existing equipment However, the long useful life of air conditioning equipment has extended the continuing use of CFC refrigerants by existing equipment. Green building groups have supported legislative action to reduce federal depreciation schedules for this equipment, which would accelerate the replacement of older equipment and hasten the total elimination of CFC refrigerant use. The HEAT Act, which Congress passed in 2017 as part of the landmark Tax Cuts and Jobs Act, reduced commercial HVAC expensing from 39 years to immediate (zero years). Phazing out ozone-depleting refrigerants The European Union is also committed to protecting the ozone layer and has some of the strictest regulations in the world. Since 2010, there has been a ban on the use of “virgin” HCFCs to service and maintain refrigeration and air conditioning equipment; use of reclaimed or recycled HCFCs for service or maintenance has been banned since 2015.
Fort Worth's historic downtown art-deco Sinclair building, now a Marriott Autograph Collection hotel, boasts its new variable refrigerant flow (VRF) HVAC system which raised the first-floor ceilings and cleared the roof for a new bar. Baird, Hampton & Brown (BHB) provided civil, electrical, and mechanical/plumbing engineering design services to make the building one of the most technologically advanced hotels in the world. Variable refrigerant flow (VRF) system As part of the renovation, BHB's mechanical engineers were tasked with replacing the building's traditional hydronic heating and cooling system with the increasingly popular variable refrigerant flow (VRF). VRF is a type of air-conditioning system that adjusts refrigerant flow to different areas of a building as needed, instead of distributing large quantities of refrigerant at all times. This technique creates practical zoning, giving occupants the ability to adjust their space temperature to their preferred comfort level. An added advantage is that VRF is one of the most sustainable systems on the market. "The VRF system helps The Sinclair be a more efficient and smarter building. A hotel room's AC unit will respond to the person who walks in and automatically know what set-point temperature they are looking for," stated Gibran Michel, BHB Associate and Senior Mechanical Designer. VRF outdoor units BHB's design of the hotel's VRF system was the firm's largest to date. Since VRF does not require as much ductwork and space as a traditional HVAC system, the team was able to raise the ceiling heights and bring in ornate windows on the lobby level. In addition, the VRF outdoor units were placed in the alleyway instead of the roof, which made room for a rooftop bar. The Sinclair held its grand opening in January 2020 and now offers a unique and modern experience while maintaining its stylish look and feel, thanks in part to its advanced VRF HVAC system.
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. Stunning OLED TVs and Displays “Creating an unforgettable experience for my guests is of the utmost importance as a developer, and I work with some of the most innovative and forward-thinking partners around the globe when developing my properties,” said Farukh Aslam, Chief Executive Officer, Sinclair Holdings. He adds, “I am very sold on LG’s technologies and the results are quite impressive, thanks to its amazing energy-efficiency and quietness, contributing to the tranquil atmosphere throughout the property.” With an eye toward implementing cutting-edge technology, the developer also incorporated a stunning array of LG OLED hospitality TVs into every guest room – the first hotel to have OLED TVs in every guest room. LG OLED technology is a high-end category of displays that deliver a picture with incredible color LG OLED technology LG OLED technology is a high-end category of displays that deliver a picture with incredible color, even from wide viewing angles. It uses self-lighting pixels that can be individually turned on and off for exact control of image brightness and quality, delivering infinite contrast ratios optimized for high-dynamic range content. In addition to the guest room displays, a number of other LG commercial displays are also featured throughout the property’s public spaces – including the lobby, restaurants and bars. “Thanks to our strong relationship with Sinclair’s owner and building managers, there are multiple products across an array of LG business units installed throughout the property,” said Donald Decker, Director of Owner Sales, LG Air Conditioning Technologies. 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.”

South Dakota’s beauty and significance is often betrayed by its lack of mentions in the national news. Largely comprised of rolling prairie, pothole lakes and crystal clear streams, South Dakota is host to many natural wonders and historically significant landmarks. The Mount Rushmore State is bookended by its two largest population centers. Rapid City lies to the west, near the iconic Black Hills and Badlands National Park, while Sioux Falls, in the southeast, is just minutes from the Minnesota and Iowa borders. Like many Western states, South Dakota has grown significantly in recent years. Its expansion has been outpaced by the growth of its largest educational institution, South Dakota State University in Brookings, just north of Sioux Falls. On-campus research and development SDSU is best known for its agriculture, pharmaceutical and nursing colleges SDSU is best known for its agriculture, pharmaceutical and nursing colleges. It now boasts roughly 12,500 students. More than one million square feet of educational space has been added over the past decade, due in part to the burgeoning need for on-campus research. “The university’s recent physical plant growth has been a combination of student housing and research facilities from all colleges,” said SDSU Senior Mechanical Engineer, Zachary Rykhus. “The Ag College is in the process of significant expansion. Two research buildings are currently under construction.” Rather than simply keeping pace with the flourishing student body, leadership at SDSU had the foresight to plan for future expansion. Cooling System Expansion “We responded to a request for qualifications issued by the South Dakota Office of the State Engineer in August of 2012,” said Greg Kronaizl, Executive Vice President at Farris Engineering Inc., adding “The University’s existing chiller plant wasn’t sufficient for the expansions they had planned and were already implementing.” Farris Engineering is a full-service MEP and fire protection design and engineering consultancy with four offices in Nebraska and Colorado. Founded in 1967 and now employee-owned, the 60-person company operates largely in the lower 48, occasionally pursuing projects abroad. The commercial, government and higher education sectors make up the bulk of their work. Raven Precision Agriculture Center A wellness center, a new football stadium, and three new agricultural buildings were recently constructed, or soon would be. Among them, Raven Precision Agriculture Center offers data analytics, soil sciences, precision crop production, plant pathology, mapping, precision farm machinery, and weed/pest control management among other related technologies. All told, there was a need for more than 4,000 tons of cooling. "Based on construction schedules, half of that load was needed quickly,” said Kronaizl. “The new plant was designed with the understanding that construction would take place in two phases, separated by several years. We provided a utilities master plan and distribution of steam and cooling lines throughout the campus in addition to the plant design.” High-end chillar plant controls installed Careful component selection resulted in a 30 percent reduction in labor cost" “Careful component selection resulted in a 30 percent reduction in labor cost,” he continued, adding “This allowed the project to move forward with the cooling capacity needed and inclusion of high-end chiller plant controls. In addition, chemical treatment of condenser water was avoided altogether.” By May of 2015, engineering work had culminated and the construction of phase one began. “One overarching theme throughout this project was to minimize wastewater,” said Kronaizl. “A good first step was to elevate the cooling towers, eliminating a great deal of the [agricultural] dust that would have otherwise settled inside and atop the cooling towers, and generally making service of all outdoor equipment easier.” EVAPCO counter-flow cooling towers installed Agricultural facilities occupy the northwest corner of the campus. Crop production studies in adjacent fields create dust at various times of the year. During phase one of the project, Midwestern Mechanical Inc. installed three, two-cell EVAPCO counter-flow cooling towers made of 304/304L stainless steel. The towers were supplied by EVAPCO’s rep firm G&R Controls. The units provide 2,250 tons of combined cooling capacity. Six, 750-ton Trane electric-driven centrifugal water chillers are installed in the chiller plant building below the towers. The facility also includes a free-cooling heat exchanger for winter cooling operation equivalent to approximately 1,000 tons. Alternative Water Treatment solutions Two other elements, non-chemical treatment solutions and the use of plastic pipe, helped reduce the amount of wastewater produced by the cooling systems and eliminate the associated cost and environmental impact of chemical treatment. “Water quality in Brookings is OK for cooling tower applications; not great but not horrible,” said Brandon Punt, Division Sales Manager at Jaytech Inc., one of the nation’s largest water management solutions providers. “Hardness and alkalinity are two concerns with source water, while microbial growth will result from atmospheric exposure if water treatment isn’t handled properly.” Pulse~Pure non-chemical water treatment system The mechanical system design includes EVAPCO’s Pulse~Pure non-chemical water treatment system for the condenser water The mechanical system design specified use of EVAPCO’s Pulse~Pure non-chemical water treatment system for the condenser water. This technology uses pulsed electrical fields to solve all three critical water treatment challenges typical of open-loop cooling systems: scale, corrosion and microbiological activity. In a Pulse~Pure system, re-circulated water from the evaporative cooling system passes through the pulse chamber where it’s exposed to alternating high and low frequency electric fields. This impacts both the surface charge of small suspended particles and free-floating microbial organisms found in cooling water. “The school was seeking a net zero discharge for sustainability reasons,” said Kronaizl. “Conserving water was equally important as avoiding chemical use. We’ve used Pulse~Pure successfully on smaller projects in the past. When we installed it at six district plants for the Lincoln District Energy Corporation, the factory support was very good, so we didn’t have any hesitation to use it on a bigger job. We also took other steps to minimize the water treatment capacity needed at SDSU.” Innovative Piping Solution Instead of piping the cooling system with steel, plastic pipe was used throughout. ISCO Industries HDPE pipe was used for all underground chilled water lines, while PP-RCT (polypropylene) was used for all condenser water piping within the cooling plant itself. “The first benefit of using plastic pipe is that it greatly reduces the amount of metal surfaces that cooling system fluid comes in contact with,” explained Kronaizl. “The second benefit was a 30 percent reduction in labor cost compared to steel pipe. Lighter material is simply easier, faster and safer to handle.” Accelerated Schedule and Optimal Control Initially, the football stadium was considered a future potential connection to the new chiller plant, as it was located on the east side of main campus and currently using remote chillers. When donor funding became available, the schedule was accelerated. The university decided to fast-track integration of the stadium with the new chiller plant. Seating 19,340 fans, the Dana J. Dykhouse Stadium is home to the SDSU Jackrabbits. “This created a shift in priorities,” said Kronaizl, further adding “Plant construction was accelerated, and the installation of chilled water lines to the stadium took precedence over providing chiller plant capacity to other buildings.” Remote Access and Automated Controls The university wanted remote access and fully automated controls at the new chiller plant The university wanted remote access and fully automated controls at the new chiller plant. Johnson Controls’ Metasys-powered Central Plant Optimization 10 was installed. This system permits interface between any brand of equipment and the JCI Metasys architecture; it uses PID feedback control, set-point adjustments, and provides efficiency curves for plant optimization. “The facility’s layout and design are as conducive as any as far as operating and maintaining the plant is concerned,” said Rykhus, adding “The plant is almost entirely automated so it does not require anyone to be on-site during normal operation.” Cooling towers installed Farris Engineering designed phase two as an exact mirror image of phase one, again, using Pulse~Pure as the sole form of water treatment. Three more, identical cooling towers are to be installed over the summer of 2019, bringing the total cooling capacity of the chiller plant to 4,500 tons. Phase one was operational in August 2016, serving the stadium and a variety of other buildings. Phase two, when complete in October 2019, will provide cooling capacity to a 60,000 square-foot Animal Disease Research addition and future Precision Ag facility. Second phase of chiller plant Krier & Blain was contracted to install the second phase of the chiller plant Krier & Blain, a large mechanical firm out of Sioux Falls, was contracted to install the second phase of the chiller plant. Roughly two years passed between the two projects, giving managers time to assess the performance of the new system’s installed components so the design could have been changed, if needed. The only change made to the original design was cancelling the installation of a screen wall around the chiller plant for aesthetic reasons. The university was initially concerned that the cooling towers would be an eyesore. This was not the case. New chillar plant installed “I conducted a full cooling tower inspection last time I was at SDSU,” said Punt, adding “The towers were extremely clean.” Despite the addition of the new football stadium, installation of the new chiller plant proceeded as scheduled, and all components of the system met the university’s expectations. South Dakota State University’s new expansion is proof that adding infrastructure does not need to increase environmental impact.
Carmarthenshire-based food wholesaler Castell Howell has become one of Carrier Transicold’s first UK customers to take delivery of the Vector® HE 19 (High Efficiency), the company’s new flagship trailer refrigeration unit. The new arrival forms part of a larger order of Carrier Transicold systems all aimed at lowering the carbon footprint of the company’s commercial vehicle fleet: Carrier Transicold is a part of Carrier, a global provider of innovative HVAC, refrigeration, fire, security and building automation technologies. Engineless Refrigeration Solution The new Vector HE 19 MT (multi-temperature) is mounted to a 13.6-metre double deck trailer – the company’s third – which are all manufactured by Gray & Adams and cooled by Carrier Transicold. It’s always very exciting to be at the forefront of new technology in our industry" As part of Castell Howell’s continuing sustainability drive, six new 15-tonne DAF LF rigid trucks, fitted with Solomon bodies and Carrier Transicold ICELAND TWINCOOL refrigeration systems, will enter service later in the year. The new vehicles represent Castell Howell’s first use of Carrier Transicold’s engineless refrigeration solution. “It’s always very exciting to be at the forefront of new technology in our industry,” said Martin Jones, director of transport operations, Castell Howell. Next-Generation Vector Unit “So getting the opportunity to be one of the first companies to use the next-generation Vector unit was obviously something we jumped at. We’ve been specifying Carrier Transicold equipment for close to 30 years, so we had absolutely no doubt the new Vector would match up to the high standards we have come to expect. Alongside the engineless options for the new rigids, it really was the next logical step for the fleet.” The new Vector HE 19’s ultra-modern re-design includes significantly redeveloped internal architecture that cuts fuel consumption by up to 30 per cent, alongside a 10 per cent saving in weight and a noise reduction of 3 dB(A) – which to the human ear equates to a 50 per cent reduction in noise – as well as up to 15 per cent savings on maintenance costs. Lower Running Costs Castell Howell’s six new rigid trucks will also be joined by two new 7.2-tonne Iveco Daily light commercial vehicles “Our trailers operate on intense trunking routes all year round, so the ability to lower running costs across the total life of the unit was a huge draw for us. The reduction in fuel, weight and maintenance costs will all add up to significant savings over time. On top of that, it’s so quiet we have to keep checking it’s not actually on standby!” added Jones. Castell Howell’s six new rigid trucks will also be joined by two new 7.2-tonne Iveco Daily light commercial vehicles, each mounted with Carrier Transicold’s light-weight Pulsor® 600 MT. The new vehicles comprise a mix of additions and replacements to Castell Howell’s 150-strong commercial vehicle fleet. The double deck trailer is expected to cover around 60,000 miles a year, with the new rigid trucks covering close to 40,000 miles on their intensive multi-drop routes. Castell Howell was founded in 1988 and has established itself as Wales’ largest independent wholesaler. Its fleet transports a range of ambient, chilled and frozen products across Wales and the south west of England.
The Convention Center is one of the most important works done in the last years in the City of Buenos Aires. It has a total capacity of approximately 5,000 people, with a plenary room and an auxiliary room, offices, meeting rooms and a 1,600 m² lobby. It consists of three underground levels to extend the landscape of the property between the University, Faculty of Law, and Thays Park. In total, it has an outdoor park of 18 thousand square meters. Preserving Green Space In addition to preserving green space and old trees, the center has a strong focus on sustainability, thanks to big windows and LED lighting to save energy, rainwater collection and solar panels. Even the HVAC system has been designed in a highly sustainable way. As the building is fully underground it is not affected by external thermal loads during the day. Furthermore, the green covering provides insulation on the roof from solar radiation, keeping internal temperature stable all year round. To guarantee the best internal comfort even during the most crowded events, the HVAC plant designer has conceived an air conditioning system based on Climaveneta branded units: 1 ERACS2-Q/CA 2222 multi-purpose heat pump and 1 FOCS2/K 6903 chiller, to produce hot and cold water for the 11 Wizard Air Handling Units.
