December 11, 2013 - There are plenty of homes that experience cold spots, drafts, cool walls and icy floors. These are often symptoms of poor insulation, an aspect of a structure that allows winter weather to make its mark all throughout a house and in its monthly heating bills.
November 21, 2013 - Schneider Electric has launched the Altivar 212 mobile programming application and drive to iPad converter cable, which allow users to perform all Altivar 212 and S-Flex drives programming through Apple iPads. The app enables an iPad to function as a drive keypad for set up using pre-loaded common default parameters for HVAC fan and pump applications, significantly streamlining the configuration process, says Schneider. Entire job close-out files can be loaded on an iPad and presented to a building owner for retention. Motor data for each fan or pump is also stored inside the app should it be required to reset the drive to the original settings loaded by the service technician during building commissioning.
October 26, 2013 - Schneider Electric unveiled an HVAC/R machine retrofit solution—Condenser Fan Pak—designed to improve both new and existing air-conditioning and refrigeration equipment.
August 26, 2013 - The CCLP low voltage relay panel from Cristal Controls is now BTL certified, promising full compatibility with most Building Management Systems (BMS) that use BACnet technology. The relay panel series can be supplied in a custom form or with seven standard models. “We are pleased to be one of the only option for relay panels with BTL certification and that means any of the big integrators in the market are now able to work with our systems without having to worry about compatibility issues” said Pierre Chaput, company president and founder.
August 26, 2013 - Johnson Controls has added ductless mini-split air conditioners and heat pumps to its York Affinity series and LX series product lines to provide more heating and cooling options to homeowners and commercial building operators.These units deliver cooling or heating to structures without installing air handlers and ductwork, and can be used to condition computer-server rooms where temperatures must be maintained. The systems combine smaller outdoor units with wall-mounted indoor units, linked by a conduit requiring a 3-in. to 4-in. opening. Single-zone mini-splits provide individualized temperature settings in a single room, while multi-zone models connect a single outdoor unit to as many as five indoor units.
August 14, 2013 - Rather than rush to turn on the air conditioner, there are simpler—and cheaper—ways to lower the temperature in your home. It all begins with minimizing the amount of heat you are generating in the first place.
July 30, 2013 - GE Energy says its ecomagination-qualified eBoost software provides data centres and IT organizations a way to reduce energy consumption and cost without sacrificing reliability, boasting increased efficiency of about 92-99% for GE’s 225-750 kVA SG series uninterrupted power supply (UPS) modules. eBoost software continuously monitors utility power quality and activates double conversion mode only when utility power quality falls outside of data centre power quality requirements, reducing the amount of time spent in a less efficient traditional “double conversion” mode, says GE. According to the company, the software also increases reliability and redundancy by enabling up to six UPS modules in parallel operation and by eliminating single points of failure.
July 24, 2013 - The new iPhone, Android and BlackBerry mobile application from ecobee allows customers to monitor and control ecobee EMS and EMS Si wireless thermostats in multiple locations. According to the company, app users can be more responsive to their tenants, employees and customers, identify and address heating and cooling problems quickly, decrease the number of unnecessary and expensive on-site service calls, and increase overall energy efficiency. With the ecobee EMS App, customers can create a custom Watch List of thermostats to keep tabs on priority spaces and locations with repeat issues, while enabling users to adjust the temperature on the thermostats remotely, based on occupancy levels.
July 3, 2013 - Available through Nirvana Chauffe-Piscine, the Silensor pump and the Nirvana pool heater claim to maximize swimming comfort while significantly reducing energy consumption and the resulting electricity bill. The Silensor pump heats the swimming pool water by recovering and distributing the heat it produces. According to the company, the pool heater will reach the desired temperature in a shorter amount of time, as the heat generated by the pump will be transmitted directly to the pool water rather than remaining inactive and unproductive in the ambient air. Annual savings are estimated at more than 35%. 
June 26, 2013 - StacoVAR mini by Staco Energy Products is an automatic power factor correction bank, including a microprocessor-based controller, which automatically adjusts to system load. StacoVAR mini extended kvar range was designed for industrial and commercial environments which rely on inherently inefficient motors for air conditioning/heating and air movement, pumps, manufacturing or warehousing equipment and more. These motors typically produce poor power factor, which can manifest itself in higher utility bills due to penalties and surcharges for poor power factor, says the company. Models are available from 11.5 kvar to 28 kvar at 208V, 15 kvar to 37.5 kvar at 240V, and 28 kvar to 75 kvar at 480V.
June 17, 2013 - GE says its new TLE series Uninterruptible Power Supply (UPS) with three-level converter technology provides mission-critical facilities with reliable power, while achieving up to 96.5% efficiency. According to GE, the TLE series features an ultra-high efficiency in double-conversion mode which provides significant life cycle cost savings for the data centre industry. For a typical enterprise-class data centre with a 6MW load, the TLE series UPS has the ability to reduce annual energy consumption by more than 2 million kWh, predicts the company.
May 29, 2013 - TSO Logic has launched its energy-efficiency software, designed to help data centres control their energy costs through TSO Metrics to show how power dollars are spent. According to the company, the software has helped pre-release customers save more than 50% on server power costs. TSO Logic’s software uses application-level inspection to determine exactly how much of a data centre’s power draw is going toward revenue-generating activities versus idle servers. This insight allows customers to save electricity without sacrificing performance-automatically controlling the power state of servers based on application demand, it says.
May 15, 2013 - According to the U.S. Department of Energy, heating, venting and air conditioning (HVAC) systems account for 32% of a commercial buildings’ energy use. To help cut HVAC-associated costs, Jaga Climate Systems, a manufacturer of heating and cooling solutions, have announced five tips to help reduce energy spend and overall costs associated with HVAC systems.
April 29, 2013 - Triad’s Chamfer ICE Airflow panels are designed with River Cooling System, boasting optimal data centre and server farm hot spot cooling for any raised floor systems that have maximum stringer width of 1.75-in. These panels are built to provide 1500-5000 lbs. of concentrated load capacities. Triad’s Hi-Plume Stratification Fin claims to provide increased upper server cooling by reducing upper/middle/lower server temperatures 5-15 degrees, while overall lowering energy consumption. In a retrofit, the Triad panels can replace existing perforated panels as a way to lower cooling costs and protect servers.
April 15, 2013 - The Blue E represents a redesign of Rittal’s Top Therm enclosure air conditioners, focusing on improving the energy efficiency of the units while maintaining cooling effectiveness. There are several elements that contribute to Blue E’s energy efficiency, Rittal says, the first of which is electronically commutated fans, which offer 30% energy savings when compared to AC fans. Blue E cooling units continue to feature nano-coated condenser coils, which allow dirt and debris to pass through without sticking. This, says the company, reduces maintenance intervals and maintains a higher level of performance. The Blue E controller, meantime, actively sample the enclosure’s interior air temperature and, when it is below 25C, it will shut off the internal fan. It will then activate the fan every 10 minutes to circulate the internal enclosure air and take a temperature reading, and repeat the process.
