HP Supercomputer at NREL Garners Top Honor

National Renewable Energy Laboratory (NREL) Feature News, Oct. 13, 2014.
http://www.nrel.gov/news/features/feature_detail.cfm/feature_id=15403

"A supercomputer created by Hewlett-Packard (HP) and the Energy Department's National Renewable Energy Laboratory (NREL) that uses warm water to cool its servers, and then re-uses that water to heat its building, has been honored as one of the top technological innovations of the year by R&D Magazine."

Modular Heating Water Boilers

Engineered Systems, Sept. 2014, by Steven G. Liescheidt.

"Usually HVAC systems and lighting are the first places most people think to start when it comes to improving energy efficiency in hospitals and health care facilities. These are, indeed, critical elements of the journey; however, one might argue that the first place one should actually start is with the building envelope, because it’s where energy savings opportunities really begin and then carry through its affiliated processes."

Variable Volume DOAS Fan-Powered Terminal Unit

"Today’s design engineers face a series of complex decisions in an effort to reduce energy consumption and maintain comfort, all while meeting a variety of codes and standards. One option that seems to satisfy all these requirements is a DOAS [dedicated outdoor air system] fan-powered terminal unit. Its combination of a variable speed ECM fan, large sensible cooling coil, and small DOAS primary air valve allows for the widest possible range of operational strategies that both minimize energy and maximize ventilation control."


Integrated Thinking at the Hilton Foundation: Combining Architecture with Operations

Business Energy, Jul/Aug.\ 2014, by Carol Brzozowski.
http://www.distributedenergy.com/DE/Articles/26496.aspx

"The Hilton Foundation building [Agoura Hills, CA], designed to exceed the US Green Building Council’s Leadership in Energy & Environmental Design (LEED) Platinum certification, is significantly more efficient in its use of energy and water than most LEED Platinum office buildings. A large contributor toward achieving net-zero energy is the design of the building’s integrated envelope and building cooling and heating systems."

Ramping Up System Performance [Hydronics]

Heating, Plumbing, Air Conditioning, Aug. 2014, by Mark Norris.

"How do you determine the efficiency of the heating system that you are recommending to a customer? It is an important question that comes up regularly, but there is no simple answer. The simple answer would be the published boiler efficiency, right? Simple, maybe, but probably not correct because the published efficiencies will rarely be an accurate representation of real system efficiency."

Evaluating Power-Demand Reduction With VFD-Controlled Systems

Heating, Piping, Air Conditioning, Aug. 2014, by Alexander L. Burd and Galina S. Burd.

Discusses the "the impact of relative dynamic-pressure losses and other factors on overall power demand and energy savings."

Tips for Updating School HVAC Equipment

Air Conditioning, Heating, Refrigeration News, Aug. 4, 2014, by Jen Anesi.
http://www.achrnews.com/articles/127240-tips-for-updating-school-hvac-equipment

"While times are hard now for many schools, some manufacturers believe an improving economy and increasing availability of alternative financing options will soon make it easier for schools to get the funding necessary for upgrades. And, in the meantime, HVAC products will continue to improve in energy efficiency, ease of installation, and life cycle."
