RTI Creates Two-Way Driver for Cool Automation HVAC Bridges

Linda Hardesty

Remote Technologies (RTI) has created a two-way driver for Cool Automation‘s CoolMasterNet and CooLinkNet universal HVAC bridges. Remote Technologies’ controls integrate and communicate with major HVAC systems based on variable refrigerant volume or variable refrigerant flow (VRV/VRF) inverter technologies, easing the installation process by eliminating the need to set up complex communication protocols. The CoolMasterNet   …Continue Reading


Are You Waiting for Your HVAC Equipment to Fail?

Martin Flusberg

We talk to many facility managers – and in our case these are managers responsible for tens if not hundreds of small facilities – who lament their official corporate policy of “run to fail,” or replacing HVAC equipment only when it breaks. This approach appears to have become the rule rather than the exception in   …Continue Reading


Aerosol-Based Duct Sealing Reduces Energy Use

Linda Hardesty

A new technology, called aeroseal, developed at Lawrence Berkeley National Laboratory with funding from the EPA and the US Department of Energy among others, provides a new way to seal leaky air ducts. JMD Corporation recently purchased the exclusive rights to the duct sealing technology and formed Aeroseal, a company that will sell the duct   …Continue Reading


BuildingIQ Uses MathWorks to Develop Energy Optimization Algorithms

Linda Hardesty

BuildingIQ engineers have developed Predictive Energy Optimization (PEO), a cloud-based software platform that reduces HVAC energy consumption in large-scale buildings by 10-25 percent during normal operation, according to the company. BuildingIQ used data analytics capabilities from MathWorks for its proactive, predictive algorithms for HVAC energy optimization. The BuildingIQ team used MathWorks MATLAB algorithms integrated in a production   …Continue Reading


Singapore Resort Increases Margins with Energy Efficiency Efforts

Karen Henry

Installing key-card-based energy management systems in hotels result in energy reductions between 20 and 30 percent. According to a Rocky Mountain Institute (RMI) blog post, this only scratches the surface of the money-saving potential that the hotel and hospitality industry can achieve through energy efficiency retrofits. To illustrate the effectiveness of comprehensive energy retrofit efforts,   …Continue Reading
