AUGUST 2018 | 43 Mechanical & HVAC Systems Another change he is seeing is a demand for Variable Refrigerant Flow (VRF) systems, which is being driven by the southern U.S. market and promoted by groups such as ASHRAE. "The argument for VRF is that it requires smaller pipes to transfer energy than traditional chiller pipes, and has a satellite plant concept rather than a central plant. A lot of research dollars are being funnelled into Heat Pump and VRF technologies right now. In Canada we have a more hybrid approach because of our colder climate, combining these new technologies with traditional boiler plants for supplemental heat. As technologies continue to advance, again, a unified code within Canada would be incredibly beneficial." Williams Engineering, renowned for being an innovator when it comes to mechanical and HVAC systems, has been supporting a variety of Passive House design and positive-energy buildings, including 1488 Alberni in Vancouver, which, when complete, will be the tallest Passive House structure in the world. Williams' goal is to reduce, minimize, and ultimately eliminate the carbon footprint of vertical infrastructures by providing clients with integrated design solutions for new and existing buildings, while implementing responsible solu- tions that take into account economic, social, and environmental issues. Another great example of sustainable mechanical solutions by Williams is the Eton at Wesbrook Village project at The University of British Columbia. Boasting a District Energy (DE) connection as its main heating source, this fully air con- ditioned project utilizes vertical stacking hybrid heatpumps that provide direct contact hydronic heating, while utilizing a water cooled compressor to generate the necessary cooling for each suite. This permits the use of an economical single hydronic piping system; operating temperatures are controlled via direct digital control [DDC] to ensure loop tem- peratures do not exceed the operating range of the hybrid heatpump unit. A fluid cooler, located on the roof of the tower, rejects any excess heat from the system. Fresh air ventilation requirements are achieved by an insulated outdoor air duct connected directly to the return inlet of each hybrid heatpump, coupled with a continuously operating system fan to circulate air to all regularly occupied spaces within each suite. "Our business is diverse and constantly changing, which inspires our team to continue to push boundaries using new technologies and enhanced processes to deliver an exceptional experience for our clients and our people. As a progressive company, we are aware of the digital transformation that is rapidly changing the way we do business and how advances in technology will continue to impact mul- tiple industries, including our own. As a result, we remain dedicated to investing in tools that help us better engage our customers as well as manage and deliver their respective projects," says Naseem Bashir, president and CEO. At Vibra-Sonic Control (VSC), while technological advancements have plateaued somewhat for this niche market that effectively addresses a wide variety of noise and vibration issues, there has been a greater understanding of the need for noise control considerations, especially as education about health and wellness in buildings increases. One of the most important principles for noise control in HVAC design is to locate mechanical sources away from noise sensitive rooms. For the most sensitive projects like performance halls, noisy mechanical equipment needs to be as far away from the noise-sensitive spaces as possible. If mechanical rooms or mechanical units must be located adjacent to noise-sensitive spaces, cost and complexity increase. In these cases, equipment needs to be in a massive, noise- blocking enclosure, and the very quietest equipment needs to be selected, which may be a cost premium to the project. The same principle applies to mechanical rooms, the walls may need to be thicker than originally planned and may require double-stud wall partitions or double-width concrete masonry unit (CMU) walls. As a result, Primacoustic has become a market leader in high-performance acoustic products. The ground-breaking Broadway acoustic panels not only grace the studio walls of international artists such as John Rzeznik (Goo Goo Dolls), Tommy Lee (Motley Crue), Nathan East (Eric Clapton) and Chad Kroeger (Nickelback), but they have also been selected by major corporations such as gaming giants Electronic Arts, Fender Musical Instruments, Meyer Sound Labs, Target, NBC Olympics, Cisco Systems, Renault and Sony. "VSC is particularly excited about the paintable and printable panels. The unique coated surface of the Paintables panels can be custom printed at your local print shop. Using UV flatbed printer technology, many commercial printers can apply custom graphics, photos, logos, or the image of your choice to the face of the panel. This high-resolution printing applies a thin coating in vivid colour without affecting the acoustic performance of the panel. Complete customization of your acoustic treatment is now possible," says Tony Adamson.
