Industrial Utility Efficiency

Penn State Health Milton S. Hershey Medical Center, Hershey Pa., is all about energy and resource efficiencies, which is why it adopted a new approach to managing its chilled water operation. The approach, which revolves around a software and analytics platform used to optimize three chiller plants in addition to various equipment upgrades, has allowed it to save 4.16 GWh/yr in electrical energy consumption – and shave $300,000 off of its annual electrical costs. With an incentive from the local utility of $415,799, the multi-phased initiative achieved a payback of 4.3 years. 
Given that HVAC systems typically account for 44% of commercial buildings’ energy consumption1, HVAC optimization should be a priority efficiency upgrade after lighting improvements and other low-hanging fruit. Full-scale HVAC optimization typically reduces energy usage and costs by 20 to 40%, improves system reliability by operating equipment more efficiently and at optimal temperatures, ensures consistently healthy air quality and building comfort, and reduces a building’s carbon footprint.
The NPE 2018 International Plastics Showcase was held at the Orange County Convention Center in Orlando, Florida, May 7-11. Setting all-time records, the Show attracted 2,180 exhibitors — including Chiller & Cooling Best Practices and Compressed Air Best Practices® Magazines! Over 1,200,000 square feet of exhibition space was used, breaking the all-time NPE record. Held once every three years, NPE 2018 registered attendance was 56,000.
Since 2002, Energy Trust of Oregon have saved and generated 728 average megawatts of electricity and 52 million annual therms of natural gas. This is enough energy to power Multnomah and Washington counties while heating Deschutes County homes. ETO has saved enough energy equal to the output of a power plant and reduced reliance on fossil fuels. In total, they have invested $1.5 billion to save customers more than $6.9 billion on their energy bills over time.
A common misconception in plastics injection molding is that coolant temperature is the one true path to achieve productivity and profitability. The reality, however, is that turbulent flow is the primary force behind efficient cooling and a key driver in the ability to achieve operational efficiencies, increase profits and consistently produce high quality products.  
The ComEd® Energy Efficiency Program offers incentives to help facilities save money by improving the efficiency of their equipment. Industries can receive standard cash incentives for common energy efficiency improvements or custom cash incentives for making improvements not included in the standard program.
An airside economizer is typically used on a packaged rooftop or tied to an indoor AHU, allowing filtered outside air into the space when outdoor temperatures drop below 55°F (12 °C) (the common supply air temperature of indoor spaces) thus alleviating the need for the refrigeration cycle to be running. Interior space is being cooled yet the refrigeration system is not running, hence the name Free Cooling.
Commercial buildings in the United States will be looking to replace centrifugal chillers as many are near or past their median replacement life of 25 years. This becomes apparent when you consider nearly half of all commercial buildings were constructed before 1980 according to data from the U.S. Energy Information Administration. The same can be said of buildings on American college campuses, which according to the same data, more than half of which were built before 1990. Bottom line — if you’re a commercial building owner or a facility manager/director in the United States, you may need to replace a chiller.
One of the most important steps in the mold making process is a consistent and proper cooling cycle. This is due to the fact cooling rates can have a significant influence on the overall quality of the finished item. The cooling cycle must remain consistent throughout the entire production run to ensure all items are equal in quality.
The Institute for Bioscience and Biotechnology Research (IBBR) connects scientists from the University of Maryland, the National Institute of Standards and Technology, and industry to find solutions to major scientific and medical challenges. With one of the nation’s largest collections of high-resolution instruments, they look inside cells and manipulate molecules. IBBR researchers have figured out the molecular structure of proteins, unraveled the protein interactions involved in autoimmune disorders and discovered possible countermeasures for antibiotic resistance.
