"There are many challenges to retrofitting a 25-year-old building to meet LEED EB Gold standards," said George Guck, Director of Facilities and Corporate Services, Frito-Lay North America. "Bolstered by the commitment of senior leadership, we completed a thorough analysis of our facility workings and evaluated new technologies to find strategic sustainable solutions that helped us meet LEED requirements."

"With each new LEED-certified building, we get one step closer to USGBC's vision of a sustainable built environment within a generation," said Rick Fedrizzi, President, CEO & Founding Chair, U.S. Green Building Council. "As the newest member of the LEED family of green buildings, Frito-Lay is an important addition to the growing strength of the green building movement."

To achieve LEED EB Certification, Frito-Lay's sustainability strategy included implementing a number of green design and construction features, water reduction technologies and practices, as well as improved waste management.

Energy reduction:

    --  Solar thermal water heating system uses the sun's light to heat all the
        hot water in the headquarters building - including the kitchen, dish
        room and fitness center. This one change reduced energy consumption by
        130,000 KWH and eliminated more than 154,000 pounds of greenhouse gases
        from being emitted into the atmosphere since installation in 2008.
    --  New high efficiency chillers reduce annual energy consumption by 975,000
        KWH and eliminate the use of harmful, ozone-depleting refrigerants.

    --  New lighting control systems, including daylight harvesting, turns off
        indoor lights when there is enough sunlight in the area, saving 266,000
        KWH per year.

Water reduction: Landscaping with native and adaptive plants reduces water needed for lawn maintenance and impedes soil erosion. The sustainable organic maintenance program minimizes environmental impacts from storm water run off.

Recycling: Frito-Lay is the city of Plano's No. 1 recycling customer. More than 70% of the company's wastes are diverted from the landfill.

Employee Education: Frito-Lay has leveraged its best practices to educate associates, and they in turn have positively impacted the community at large. Frito-Lay hosts an annual Eco Fair for its associates to showcase local green vendors. The information, services and products are resources employees can take home and to their communities.

Owens Corning's Gresham facility uses 100 percent green renewable energy and a blowing agent that does not deplete the ozone to produce its GREENGUARD-certified FOAMULAR(R) insulation, which conserves energy and reduces greenhouse gas emissions of homes and buildings.

Created by Owens Corning, the Gresham plant's revolutionary blowing agent is the first of its kind to be used in a Pacific Northwest facility.

By manufacturing its FOAMULAR(R) insulation closer to its customers, Owens Corning's Gresham plant will prevent emissions of more than 500 tons of carbon dioxide each year - the equivalent of more than 50,000 gallons of gasoline - that would have been expended to transport the insulation from other production facilities.

"We are proud that Owens Corning's Gresham facility has been recognized with LEED Gold certification, and that the FOAMULAR(R) insulation produced there helps reduce greenhouse gas emissions and conserve energy," said Frank O'Brien-Bernini, chief sustainability officer, Owens Corning. "This honor highlights Owens Corning's unwavering commitment to its sustainability goals, including greening our operations, greening our products and accelerating energy efficiency improvements in the built environment."

LEED certification is a nationally accepted benchmark for sustainable green building practices. It promotes a comprehensive approach to sustainability by recognizing superior performance in five key areas of environmental health: sustainable site development, water efficiency, energy usage, materials selection, and indoor air quality. More than 3,850 buildings in the United States are currently LEED certified.

"Building operations are nearly 40 percent of the solution to the global climate change challenge," said Rick Fedrizzi, president, chief executive officer and founding chair, U.S. Green Building Council. "While climate change is a global problem, innovative companies like Owens Corning are addressing it through local solutions."

The second project is a major renovation of an existing senior citizens facility. The building systems are being redesigned/upgraded to make the building at least 40 percent more energy-efficient than the Canadian Model National Energy Code for Buildings. MCW Consultants Ltd. is using IES to size the equipment and evaluate the energy performance during the design stage. This building will feature many unique systems, including ground source heat pumps, heat recovery, superior building envelope components and low wattage lighting.

The third project is an education centre and animal hospital, which is an existing LEED Gold building. MCW Consultants Ltd. has used IES to size equipment for energy retrofits and upgrades, such as a ground source heat exchanger and changes in building operation. The model geometry was created in Revit and imported via gbXML.

"We selected IES as part of an overall shift toward Building Information Modelling (BIM)," said Brian Tysoe, M.Sc., LEED AP and Building Simulation Specialist for MCW Consultants Ltd. "The established methodology of performing manual takeoffs to do load calculations with one program, and energy modelling with another program is extremely time consuming and repetitive. IES allows us to use a common model for both of these tasks, and the interoperability of IES with SketchUp and Revit allows for a more iterative process, where we can get involved in design at an earlier stage of the project."

MCW Consultants Ltd. is using a range of IES solutions on these projects, including ApacheSim, ApacheLoads, ApacheHVAC, RadianceIES and MicroFlo. ApacheSim to perform hour-by-hour simulation; ApacheLoads to size equipment; ApacheHVAC to create detailed HVAC network models; RadianceIES to produce high quality, photorealistic images of the buildings and analyze daylight levels; MicroFlo to visualize air movement and temperature stratification; and Apache Constructions Database Manager to evaluate condensation in exterior wall constructions.

"Our <VE> software tools enable designers and engineers to customize their analysis, providing them with specific output to fit their needs and identify solutions for the questions they are investigating," said Kevin Settlemyre, president of IES North America. "Combined with the integration directly with Revit and SketchUp, MCW Consultants Ltd. is able to make and evaluate changes throughout the process. We are providing them with the tools to design high performance buildings in a shorter period of time, while assisting to facilitate an integrated design process and on into operations."

The first project is a new 230,000 square foot speculative office tower which is targeting LEED Gold certification. On this project, MCW Consultants is using IES to perform LEED energy modeling and evaluate design options. In the early stages, IES' energy model was used to advise the architect on their envelope design based on energy consumption and peak loads. The same model is now being used to evaluate HVAC equipment. It will also be used for the LEED submission to the U.S. Green Building Council, the company said.

The programmable LDO embedded in the SC418 can be used to provide the 5V necessary for the gate drive bias, allowing true single input rail operation. Internal crossover circuitry (another feature specific to Semtech's products) optimizes efficiency by bypassing the LDO after startup if the LDO and buck outputs are the same.

Semtech's Smart Power Save technique enables the SC418 to re-enter continuous conduction mode when active loads attempt to pull the output high while in power save mode, pulling the output back down and avoiding over voltage latch-off.

"The SC418 and SC419 take the same sophisticated architecture embedded in our SC414 and SC417 integrated regulators and provide the user with a flexible, efficient controller that can be used to optimize solutions for a wide range of applications," said Alan Burchfield, Senior Product Marketing Manager for Semtech's Power Management Group. "This device is packed full of features that optimize efficiency, minimize noise and make it as easy as possible for engineers to use."

Pseudo fixed frequency adaptive on-time control gives the parts transient response while reducing the output filter capacitance required and simplifying the design process by removing external compensation components. The controller can be readily set up to allow output voltages up to 12V, will support full ceramic output capacitor solutions, and will start up into a pre-biased output. The strong gate drives provide enough current to power a single phase solution up to 30A.

The SC418 and SC419 have built-in soft-start, cycle-by-cycle current limiting, over-temperature, over-voltage and under-voltage protection features. They also include a power good output for the switching regulator, which may be used for diagnostics and sequencing.

Key Features of the SC418 and SC419

- Wide input voltage range: 3V to 28V

- Programmable 150mA LDO can be used to provide gate drive bias for a single rail solution (SC418)

- SmartDrive reduces EMI and eliminates the need for snubbers or gate drive resistors

- Automatic LDO crossover circuitry optimizes efficiency for VOUT = VLDO (SC418)

- Selectable continuous conduction mode, regular power save, and programmable frequency ultrasonic power save (patent pending)

- Fully protected - built-in soft-start, cycle-by-cycle current limiting, over-temperature, over-voltage and under-voltage protection features

- Compact ultra-thin 3mm x 3mm Pb-free, halogen-free, RoHS/WEEE compliant package

The SC418 and SC419 are available immediately in production quantities.

These parts bring to the MicroClamp platform Semtech's proprietary EPD process technology, an improvement over silicon avalanche diode processes that delivers low standoff voltages to reduce leakage current and capacitance. Semtech became the first company to debut a true 2.5V TVS when it launched the four-line, ultra-low capacitance RClamp2504N and RClamp2504P in May 2009.

The use of low voltage chipsets also helps these smartphones to have a longer battery life. With standard features including cameras, Internet browsing, email and texting in addition to voice communications, smartphone designers need to take advantage of every opportunity to extend the battery life, such as choosing parts with low leakage current like the uClamp25x1T devices, which feature a 10nA leakage current. Both TVS devices come in ultra small 1.0 x 0.6 x 0.4mm package to provide flexible protection anywhere it's needed.

The uClamp25x1T devices provide industry-standard protection from electrostatic discharge (ESD), lightning, electrical fast transients (EFT), and cable discharge events (CDE). The uClamp2501T is unidirectional and the uClamp2511T is bidirectional. The uClamp2511T offers a low capacitance of 10pF maximum, while the uClamp2501T is rated at 30pF.

"Portable-system designers that need to balance the increased battery life made possible by low voltage chipsets with the reliability that comes with high-quality protection now have a great option," said Rick Hansen, Semtech Marketing Director for Protection Products. "Providing the high-quality protection of the MicroClamp platform with both low-voltage and low leakage is a significant breakthrough."

While these products offer designers the benefit of significant board space savings, their small size and RoHS & WEEE compliance also contributes to energy conservation and hazardous waste reduction.

Key Features of the uClamp2501T and uClamp2511T

-- Transient protection for data lines to IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact), IEC 61000-4-4 (EFT) 40A (tp = 5/50ns) and Cable Discharge Events (CDE)

-- Ultra-small package (1.0 x 0.6 x 0.4mm)

-- Low leakage current: <10nA typical (VR=2.5V)

-- Low Operating voltage: 2.5V

-- Low capacitance: <10pF (uClamp2511T)

-- Low capacitance: <30pF (uClamp2501T)
