"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.

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."

Hope for the Homeless: Bud Clark Commons [Portland, OR]

High Performance Buildings, Summer 2014, by Jeff Becksfort.
http://www.hpbmagazine.org/File%20Library/Case%20Studies/Summer%202014/040-049_BudClarkCommons.pdf

"...the new LEED Platinum certified building provides residents access to services via a walk-in day center; transitional and temporary beds; and efficient studio apartments for 130 women and men. Rent and utilities are subsidized based on resident income. The Center uses a range of highly efficient systems, including graywater reclamation and one of the largest solar hot water heating systems in the Northwest. The eight-story building is 51% more energy efficient than a similar building as defined by ENERGY STAR Target Finder median building performance."

Chiller Retrofits In Health Care Facilities

Engineered Systems, Jul. 2014, by Gary Hamilton. (Free registration required to view full-text.)

"One of the worst things you can do is note the capacity and replace the chiller. Have the building loads and usage changed? What about motors and cooling towers? Consider these and your part-load realities to create real long-term improvements."
