Are Chilled Beams Viable in Humid Climates?

Buildings, Jan. 2016, by Daniel Kailey.
http://www.buildings.com/article-details/articleid/19494/title/are-chilled-beams-viable-in-humid-climates-.aspx

"As the effort to improve energy efficiency in buildings increases, many new technologies are under consideration by designers, builders, and owners.  The use of chilled beams, a technology that has been successfully employed to improve energy performance in European buildings for decades, is gaining popularity in the United States. But can this technology be used effectively in the hot, humid environments that much of the U.S. experiences every summer?"

Microsoft Plumbs Ocean’s Depths to Test Underwater Data Center

DOE Industry Partnerships Lead to Widespread Adoption of Efficient Commercial Air Conditioners

U.S. Department of Energy Building Technologies, Jan. 14, 2016.
http://energy.gov/eere/articles/doe-industry-partnerships-lead-widespread-adoption-efficient-commercial-air

"Commercial air conditioners, often referred to as rooftop units (RTUs), are commonly used across commercial building sectors such as schools, restaurants, big box retailers, and small office buildings. These heating, ventilation and air conditioning units condition almost half of all U.S. commercial floor space. But commonly they are old and inefficient, wasting anywhere from $900 to $3,700 per unit annually. To take advantage of this energy and cost savings opportunity, the Department of Energy (DOE) partnered with manufacturers and businesses to launch a multi-faceted program that has transformed an entire market—from a time not long ago, when zero high efficiency RTUs were commercially available, to a historic standard that ensures all businesses will have access to energy-saving RTUs. Learn about the process step-by-step below."

Commercial Air Conditioners & Furnaces: Energy Department Announces Largest Energy Efficiency Standard in History

U.S. Department of Energy, Dec. 17, 2015.
http://energy.gov/articles/energy-department-announces-largest-energy-efficiency-standard-history

"The U.S. Department of Energy today announced historic new efficiency standards for commercial air conditioners and furnaces. Developed with industry, utilities, and environmental groups, these standards will save more energy than any other standard issued by the Department to date. Over the lifetime of the products, businesses will save $167 billion on their utility bills and carbon pollution will be reduced by 885 million metric tons."

HVAC SAVE: A Case Study in the Next Evolution of Residential Quality Installation Programs

 

Midwest Energy Efficiency Alliance, Dec. 2015.

"MEEA partnered with Energy Stewards International (ESI) to develop the HVAC SAVE program to train and certify HVAC contractors in the skills necessary to determine in-place efficiency of functioning HVAC systems. There are two main components to the HVAC SAVE program: contractor training and field performance testing. The goal of the combination of these two elements is to have the contractors take what they have learned in the classroom, apply it in the field by optimizing installed equipment, and then verify their installation through real time web-based diagnostic testing."

"When the efficiency of a facility’s plumbing and HVAC systems is maximized, building owners realize energy- and operational-cost savings. Optimal efficiency can be achieved through seasonal maintenance and best practices regarding water pumps."

HVAC Contractors Prepare for DOE Efficiency Mandates

Air Conditioning/Heating/Refrigeration News, Oct. 18, 2015, by Joanna R. Turpin.
http://www.achrnews.com/articles/130794-hvac-contractors-prepare-for-doe-efficiency-mandates

"At the beginning of the year, the U.S. Department of Energy’s (DOE’s) minimum efficiency standards for residential air conditioners and heat pumps went into effect, dividing the country into three regions — North, South, and Southwest. The standards dictate that contractors in the latter two regions are allowed to install 13-SEER heat pumps and air conditioners until mid-2016 (or until supplies run out); then, they must only offer 14-SEER (or higher) equipment. Many HVAC distributors in those regions stocked up on 13-SEER equipment ahead of the deadline and are happy to see that their bets paid off as the inventory flew off the shelves."
