The traditional, and still dominant, uses of energy modeling are all associated with building design, such as HVAC system selection and sizing and code compliance. But energy modeling has impactful post-occupancy uses as well.
DOE verified demos show energy savings of up to 80%
July 4, 2016
Through a the U.S. Department of Energy (DOE) Small Business Innovation Research (SBIR) grant, Kansas City, Missouri-based QM Power recently commercialized a high-efficiency motor for commercial refrigerators that has the potential to transform the market.
Did you know that an HVAC system can produce up to 20 gallons of water a day? Due to this fact, as much as 90 percent of central air conditioning service calls are to address water leaks caused by condensation.
SINGH360 Helps Strack & Van Til and Coborn’s trim energy consumption
June 6, 2016
Two prominent grocery chains in the Upper Midwest are reducing their energy use and cutting energy cost by retro-commissioning their stores. The chains have done so with the help of SINGH360, a service provider that specializes in working with grocery chains.
Improved IAQ could significantly improve the performance of workers
May 23, 2016
People who work in well-ventilated offices with below-average levels of indoor pollutants and carbon dioxide (CO2) have significantly higher cognitive functioning scores — in crucial areas such as responding to a crisis or developing strategy — than those who work in offices with typical levels, according to a new study.
Barksdale Air Force Base is no stranger to hot weather, which can be a constant battle for maintainers and others who work out in the elements. Thankfully, 2nd Civil Engineer Squadron HVAC Airmen ensure there’s a cool place to escape to while also providing other benefits of heating and cooling that directly affect the mission.
Parallel compressor refrigeration racks have been the primary source of refrigeration for the grocery store industry over the years. In this article I am going to go over the benefits a parallel rack system can offer the commercial and industrial refrigeration markets.
Hospitals today are increasingly being challenged by rising patient infection rates, especially from superbugs such as Methicillin-resistant Staphylococcus aureus (MRSA). And the challenges are only going to increase as new Medicare rules go into effect in 2017 that will include MRSA in all reimbursement calculations.
It is my firm belief that airflow and air distribution is every bit as important in refrigeration design as load calculations. What good is a properly sized system that can’t deliver the air to areas that need it? Poor air distribution and airflow lead to stratification in temperature and humidity as well as poor heat transfer.
Finding R-22 and R-410A alternatives for high-ambient-temperature environments
March 7, 2016
The Oak Ridge National Laboratory (ORNL) High-Ambient-Temperature Evaluation Program for low-global warming potential (GWP) refrigerants aims to develop an understanding of the performance of low-GWP alternative refrigerants to HCFC and HFC refrigerants in mini-split air conditioners under high-ambient-temperature conditions.
