"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."


The Fine Art of Making Energy Visible

/Energy_Visible_26497.aspx


"One of the boldest experiments in energy efficiency collaboration in the US is now well underway in Vermont, where cold winters and other factors drive some of the highest energy costs in the country. It’s spearheaded by a new kind of utility known as Efficiency Vermont and run by the non-profit Vermont Energy Investment Corporation (VEIC). This new utility is the first of its kind, though similar initiatives have emerged in Oregon, Washington DC, and the Ohio region. Efficiency Vermont provides electricity to stakeholders, not by building power plants, but by helping existing consumers use less energy and use it wisely."

Minimizing Risks with Solar Roofs

"Commercial rooftops are an attractive platform for the installation of solar photovoltaic (PV) electricity-producing systems. These low-slope roofs offer an economical and sustainable structural foundation for renewable solar energy."

Integrated Thinking at the Hilton Foundation: Combining Architecture with Operations

Business Energy, Jul/Aug.\ 2014, by Carol Brzozowski.

"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."

Efficient Building Water Use

Consulting-Specifying Engineer, July 2014, by Willa Kuh and Fred Betz.
http://www.csemag.com/single-article/efficient-building-water-use/5c43e78511f4c18036dd0e018167ce82.html

"The escalating cost of providing potable water in the United States is creating new urgency for owners of commercial, industrial, and institutional buildings to respond with greater engineered water efficiency."

Battle of the Kilowatts: Challenge Occupants to Reduce Energy with Games and Competitions

Buildings, July 2014, by Jennie Morton.

"The relationship facility managers have with tenants can be a wary one at best, fraught with skirmishes over space heaters, thermostat settings, and light levels. But with the growing impact of plug loads, building owners need to recognize that human behavior can make or break an efficiency program."

Destination: Certification: 6 Steps to Navigate LEED 2009 and v4 for Existing Buildings

Buildings, July 2014, by Janelle Penny.
http://www.buildings.com/article-details/articleid/17640/title/destination-certification.aspx

"For the next 11 months, your LEED for Existing Buildings certification plans will face a fork in the road. Projects can register under either LEED 2009 or v4 until June 2015, when the field narrows to just v4. So which is best for your facility? Whichever path you’re on, it’s vital that you chart smart. Consider these six steps to lay out the best route to certification success."

Green Building Report: The Real Costs Of Major Energy Upgrades

Building Operating Management, July 2014, by Stefan Domby.
http://www.facilitiesnet.com/energyefficiency/article/Budget-For-Energy-Upgrades-Requires-Fully-Understanding-Real-Costs--15128

"Both in the private and public sectors, building owners and facility managers are focusing on managing energy costs more than ever before. But as we all know, you have to spend money to save money. It's important for facility managers to develop a plan to ensure that they do not run out of money before completion of the project and that the project budget is justified."
