Design Uses Air Curtains on Entrances as well as High-Efficiency Chillers, Boilers, and Rooftop Units
June 23, 2014
The University of Pittsburgh Medical Center (UPMC) set out to make the new $252 million Monroeville, Pennsylvania, facility the most sustainable of its 30-hospital network. Its design team delivered a building that’s saving an estimated $350,000 to $500,000 in annual energy savings.
Looks at Whether Retailers Save Money by Minimizing Risk of Equipment Failure and Reducing Service Calls
June 9, 2014
Alpine Mechanical Services has announced the completion and results of a collaborative energy efficiency study on rooftop units conducted by Alpine Mechanical, Siemens Industry, and Nexant. The study tested the efficacy of HVAC preventative maintenance best practices in a retail environment.
This analysis shows how a water-cooled 500-ton chiller system when compared to a 500-ton air-cooled chiller system results in approximately $45,000 in annual operating costs savings. Additionally, the water-cooled system reduces peak energy demand by 45 percent.
It’s all about price, isn't it? That's why every company that sells high-end items is going out of business. But wait a second; they are not going out of business. In fact they are profiting like never before.
Welcome to year zero. The waiting is over and the F-Gas regulation has passed into law and life as we know it changes forever. Over-dramatic? Well, it will be a dramatic shift for everyone in the industry who thus far have somehow managed to avoid all the noise from the supermarkets about the need to move away from HFCs.
R-1234ze Has a Global Warming Potential Lower Than One, Better Than CO2
June 9, 2014
The first UK-manufactured chiller incorporating the low global warming potential (GWP) HFO refrigerant R-1234ze is now cooling shoppers visiting the new £15 million John Lewis department store that opened in York.
Bob and Tim were on their way to a no cooling call. The spring season was still cool at night and warm in the daytime. The customer told the dispatcher, “The unit started up at about 10:30 a.m. this morning and made a noise, but did not cool the house, even though it is still running.”
The challenge presented by Neema Hospitality, Mechanicsburg, Pennsylvania, was that the company wanted to maximize energy efficiency while maintaining guest comfort and loyalty, improve profitability without increasing room rates, and augment operational efficiency with remote monitoring capability.
Taken separately, workers’ compensation laws, the Americans with Disabilities Act (ADA), and the Family and Medical Leave Act (FMLA) represent complicated laws that are often difficult to figure out. When workers must be absent from the workplace under two or three of these laws, the situation becomes even more complex.
