The Social Security Administration’s re-introduction of No-Match Letters, along with U.S. Immigration and Customs Enforcement’s skyrocketing issuance of Notice of Inspections of I-9s, evidences the federal government’s increasingly aggressive stance to curb the hiring of unauthorized workers and to penalize employers who do.
The EnOcean Alliance announced that it has signed up its 200th member company, NanoSense. NanoSense develops products using EnOcean and KNX technologies that regulate and optimize air quality inside buildings. Originally created in April 2008 by Distech Controls, EnOcean, Masco, MK Electric, Omnio, and Thermokon, the alliance now counts 200 members from 20 different countries.
The U.S. Department of Energy (DOE) has published a final rule establishing federal test procedures for walk-in coolers and freezers. In the rule, DOE adopted by reference Air-Conditioning, Heating, and Refrigeration Institute (AHRI) Standard 1250 (I–P)–2009, ‘‘Standard for Performance Rating of Walk-In Coolers and Freezers.”
A variable frequency drive (VFD) fails to vary the discharge-air fan speed. A motor overheats and fails prematurely. While each troubleshooting problem in an HVAC system presents its own unique set of circumstances, HVAC professionals may recognize such problems as possible power quality issues.
The moisture content in a school’s building envelope can provide the medium that mold needs for incubation and growth. Whether a school is under construction or unoccupied during the summer break, it likely is without an HVAC system to help control moisture. Without humidity control, school buildings can become a breeding ground for mold and mildew.
The bottom line is that if there is no sale made or no money coming in, there is no company. One thing that seems to elude contractors at times is their ability to ask for the order. In other words, “close the sale.” Years ago I learned to plan your close in advance and build your sales presentation around it.
The U.S. Department of Energy (DOE) and the U.S. Department of Education have joined with the National Science Teachers Association to launch America’s Home Energy Education Challenge, a new energy education initiative. The goal is to motivate students across the country to learn about energy efficiency and help their families save money.
America, with its entrepreneurial spirit and innovative national labs, will lead the global clean-energy revolution and reap the economic and environmental benefits that go with it, Vice President Joe Biden stated in a visit to the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL).
The High-Performance Building Congressional Caucus Coalition (HPBCCC), established by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), will highlight the importance of high-performance buildings to federal, state, and local policymakers and the general public during High-Performance Building Week, May 23-29.
Claims that air curtains installed on walk-in cooler entrances save energy and refrigeration equipment wear-and-tear have been corroborated by a fast food restaurant’s audited energy test. The results indicate the compressor ran 1.75-hours less during one week - a 27 percent reduction in compressor run-time and equipment wear-and-tear.
