June 22, 2012 - Lennox claims its energy-efficient Energence rooftop units are now just got even more eco-friendly—with the addition of a new all-aluminum condenser coil that significantly reduces refrigerant charge requirements. The coil uses up to 45% less refrigerant than a traditional tube-and-fin condenser coil, and its all-aluminum construction offers a lighter unit weight, shaving approximately 90 lbs from a 10-ton rooftop unit. The Energy Star-qualified rooftop unit also exceed ASHRAE 90.1-2010 minimum standards by more than 35%.LENNOX INDUSTRIES
June 22, 2012 - The new iFan System from Serco Company claims to generate cost savings by coordinating multiple high velocity low speed (HVLS) large fans from a centralized location to minimize energy usage and maximize performance. A single iFan system is capable of controlling 30 networked HVLS warehouse fans per configuration and are networked to a 23" touch screen computer, enabling changes to fan operation based on manual control or in response to system metrics based on each fan, zone or the entire facility. Serco fans are represented by Dock Products Canada.SERCO COMPANY
June 14, 2012 - The application of geothermal (ground-source) HVAC systems is growing rapidly in both the residential and commercial markets. These systems offer premium efficiency because they use the relatively constant temperature of the earth to heat and cool.
June 7, 2012 - Cerus Industrial has enhanced its P-series line of variable frequency drives (VFDs) for HVAC use with new control options and safety features, FastApp – an application-based commissioning tool designed to save time when setting up HVAC applications. With FastApp, the company claims HVAC motor control parameters are now easier to set up via the keypad on the drive enclosure, and include display and control options, such as: PSI, oF, oC, inWC, inM, Bar, mBar, Pa, kPa, and custom factors, including level, line speed and other parameters. The enhanced VFDs also have safety features to help protect motors from damage due to conditions such as belt loss.CERUS INDUSTRIAL
May 9, 2012 - Cerus Industrial, a manufacturer of intelligent motor starters for HVAC systems, has developed the multi-contactor starter (MCS) designed to control two speed, two winding, and two speed, one winding re-connectable motors. The starter has a built in timer and control functions that reduce the number of separate components needed for the typical installation, simplifying wiring and improving system reliability, explains the company. It also features a class 5-30 electronic overload and wide range voltage operation (120 to 480 VAC) for different applications.CERUS INDUSTRIAL
May 9, 2012 - Rittal is now offering RiTherm– an iPhone, iTouch and iPad app which calculates climate control requirements for individual enclosure assemblies. The app provides a compact variant of the full software version "Therm 6.1" and guides users to the most suitable, climate control component: project title, parameter, enclosure, selection, recommendation.RITTAL SYSTEMS
April 10, 2012 - Rittal claims its CSA-certified air conditioners of the 'Blue e' generation can help achieve energy savings of as much as 70%. Depending on the application, the units boast a cooling output range of 500 W to 4,000 W. According to the company, the units feature nano-coating, optimized fan technology and improved control electronics via new Eco-Mode controls. This means that if an internal fan doesn't need to operate continuously, it is automatically switched off.RITTAL
March 24, 2012 - The exterior environment of a building envelope is subject to ever-changing environmental conditions such as wind, humidity, rain, sun and ambient temperature. One of the most significant influences on the building envelope design is the sun. The sun is composed of ultraviolet, visible and infrared light that is dynamic and constantly changing relative to the building. Designs that do not take the sun’s influence into account can subject the occupants of the building to conditions such as uncomfortable glare, solar heat gain, variable temperatures, and the early decay of fabrics, and surfaces that fade over time.
March 6, 2012 - ASHRAE is encouraging facility owners, engineers, designers, architects and others on the building team to download Advanced Energy Design Guide for Medium to Big Box Retail Buildings: Achieving 50% Energy Savings Toward a Net-Zero-Energy Building, which aims to create a cost-effective design for retail buildings with gross floor areas between 20,000 - 100,000 sf. The guide features recommendations for different climate zones, case studies and technology examples, best practices and proposed energy-use targets. CLICK HERE for a free download of the guide. Additional design tips include: daylighting solutions, sample design layouts for ambient lighting, ways to reduce exterior lighting energy use, and HVAC ventilation air control strategies.ASHRAE
March 2, 2012 - Rittal claims its new TopTherm fan-and-filter units are the first in the world to use diagonal fan technology, which help ensure better air throughput and improved ventilation in enclosures and housings. The units also boasts energy savings of 43%. The fan-and-filter units are available in various outputs, ranging from 20 m3/h to 700 m3/h. There is also a choice of 24 V (DC) or 115 V, 230 V and 400 V 3-phase (AC, 50/60Hz) supply voltages.RITTAL
February 1, 2012 - Mitsubishi Plastics, in collaboration with Union Industry, has developed a compact adsorption chiller with an integrated cooling tower (cooling capacity of 10 kW). The chiller, which uses the zeolitic water vapour adsorbent AQSOA, is capable of being incorporated into a solar water-heater, which can help to significantly reduce electricity use and save energy, says the companies. When the product is combined with a cogeneration system, the system is expected to reduce electricity consumption by up to 20% from that of coolers with compressors, they add. Mitsubishi Plastics started test-marketing the chiller to the U.S. market last month.MITSUBISHI PLASTICS
January 30, 2012 - Changes to help make buildings and systems more sustainable are part of the newly published version of the high performance green building standard from ASHRAE, the U.S. Green Building Council (USGBC) and the Illuminating Engineering Society (IES). ANSI/ASHRAE/USGBC/IES Standard 189.1-2011, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings covers key issues of energy efficiency, indoor environmental quality, and site sustainability, among other topics. The standard also updates the performance option for energy efficiency (Appendix D) so that it refers to Appendix G of Standard 90.1-2010. Appendix G of 90.1 applies to projects seeking to reduce annual energy cost more than would be possible by merely meeting the requirements of that standard.  ASHRAE
January 9, 2012 - Jaga Climate Systems describes its new in-floor Micro canal radiator as a small and powerful heat exchanger that operates with quiet fans to ensure heating is virtually noiseless. At 6 inches high and 13 inches wide, the Micro Canal generates heat output while responding to changing temperatures. According to Jaga, the advanced trench-heating unit saves energy with its low-H2O technology, and is an ideal solution for when space is limited. JAGA CLIMATE SYSTEMS
January 4, 2012 - Equipped with expanded control logic, the Viessmann Vitodens 100 condensing space heating boiler can now deliver on-demand domestic hot water (DHW) with the new CombiPlus Kit. At a size of 9.8" x 17" x 8.7", the optional CombiPlus Kit can be mounted underneath or beside the boiler as part of a new boiler installation or as a later addition to the Vitodens 100. Generating up to 3.6 GPM of on-demand DHW, the kit eliminates the need for a DHW storage tank in some lower-load applications where space is at a minimum. Built-in temperature and flow sensors are included and DHW heating is managed through the boiler’s on-board control.VIESSMANN MANUFACTURING
