EPA Reports 3.9 Percent Increase In U.S. Energy-Related CO2 Emissions in 2010

U.S. carbon dioxide emissions from the consumption of fossil fuels were 5,638 million metric tons carbon dioxide (MMTCO2) in 2010, an increase of 3.9% from the 2009 level, according to…

U.S. carbon dioxide emissions from the consumption of fossil fuels were 5,638 million metric tons carbon dioxide (MMTCO2) in 2010, an increase of 3.9% from the 2009 level, according to Energy-Related Carbon Dioxide Emissions 2010, an online analysis released today by the U.S. Energy Information Administration (EIA). This is the largest percentage increase in U.S. energy-related carbon dioxide emissions since 1988. However emissions are still 6% below the 2005 level. Since 1990, U.S. carbon dioxide emissions have grown at an average annual rate of 0.6%.

Among the factors that influenced the rise in emissions was an increase in the Gross Domestic Product (GDP) of 3%. In addition, the energy intensity of the U.S. economy, measured as energy consumed per dollar of GDP (Energy/GDP), increased by 0.7% in 2010. There was also a slight increase in the carbon dioxide intensity of U.S. energy supply (CO2 per unit of energy) in 2010, which is in contrast to a drop of 2.4% in 2009. Consumption of coal, the most carbon-intensive fossil fuel, rose by 6% in 2010 after falling by 12% in 2009.

Another Drop for Architecture Billings Index in September 2011

Following the first positive score in four months, the Architecture Billings Index (ABI) reversed direction again in September. As a leading economic indicator of construction activity, the ABI reflects the approximate nine to twelve month lag time between architecture billings and construction spending. The American Institute of Architects (AIA) reported the September ABI score was 46.9, following a score of 51.4 in August. This score reflects a sharp decrease in demand for design services (any score above 50 indicates an increase in billings). The new projects inquiry index was 54.3, down from a reading of 56.9 the previous month.

“It appears that the positive conditions seen last month were more of an aberration,” said AIA Chief Economist, Kermit Baker, PhD, Hon. AIA. “The economy is weak enough at present that design activity is bouncing around more than usual; one strong month can be followed by a weak one. The economy needs to be stronger to generate sustained growth in design activity.”

Key September ABI highlights:

  • Regional averages: Midwest (51.0), Northeast (50.8), South (47.3), West (46.7)
  • Sector index breakdown: commercial / industrial (52.4), mixed practice (50.0), institutional (48.0), multi-family residential (46.4)
  • Project inquiries index: 54.3

Litecontrol recently unveiled its new Vertex luminaire, a high-performance indirect/direct pendant fixture sized for T8 lamps and optically designed to provide efficiencies as high as 90%. The Vertex provides a distribution of 65% uplight and 35% downlight. Optional optical components can be added to alter the distribution for 35% uplight with 65% downlight, 20% uplight with 80% downlight, or 100% downlight. The rectilinear sides and angled lower housing create a low-profile, visually appealing fixture, suitable for classroom and other school and university applications. Vertex is available with either a white blade baffle option or a soft glow lens option. This Cradle to Cradle Silver Certified luminaire is also available with a fixture-integrated photosensor that enables Litecontrol’s CS/dlh daylight harvesting Control Solution.

Cree, Inc. recently announced the commercial availability of high-voltage XLamp XT-E and XM-L LEDs. These new LEDs enable the use of more efficient, smaller drivers to reduce cost for compact lighting applications such as candelabras and retrofit lamps.

The XLamp XM-L LED delivers up to 600 lm in Cool White (6000K) and up to 462 lm in Warm White (3000K) at 6W, 85°C. The XLamp XT-E LED delivers up to 300 lm in Cool White (6000K) and up to 228 lm in Warm White (3000K) at 6W, 85°C. Both LEDs have a typical voltage of 46V at binning conditions.

OSRAM SYLVANIA And Veolia Environmental Services Expand Recycling Partnership to Canada

Veolia ES Technical Solutions, LLLC, the hazardous waste division of Veolia Environmental Services North America Corp. (VESNA), and OSRAM SYLVANIA recently announced the expansion of their joint online program to…

Veolia ES Technical Solutions, LLLC, the hazardous waste division of Veolia Environmental Services North America Corp. (VESNA), and OSRAM SYLVANIA recently announced the expansion of their joint online program to offer RecyclePak recycling kits into Canada.

This collaboration began in 2006 when OSRAM SYLVANIA sought a lamp recycling solution for customers’ small quantities of mercury-containing lamps and ballasts. Veolia Environmental Services’ RecyclePak lamp and ballast recycling kits provided that solution, and the two companies launched an industry-first web program, at Greenbuild that year in Denver. Working together, they also designed and introduced the first recycling kit for small quantities of CFLs generated by consumers.

RecyclePak is Veolia Environmental Services’ complete pre-paid lamp and ballast recycling solution. One price includes everything needed to recycle including shipping to and from a facility, packaging and recycling and written compliance documentation. Veolia Environmental Services’ RecyclePak program not only provides a convenient recycling option, it also ensures complete compliance with state, provincial and local disposal regulations while reducing the risks associated with improper storage.

The Lighting Quotient and the Illuminating Engineers Society have announced the third annual Sylvan R. Shemitz Memorial Scholarship, created in honor of Lighting Quotient founder Sylvan R. Shemitz, which aims to support the future generation of lighting designers, engineers and architects. The $2,500 prize will be awarded to a student who demonstrates creativity, vision and knowledge in the field of architectural lighting.

To apply, students must read the facility description and follow the project requirements, including a lighting plan, lighting fixture schedule and specifications (available for download here). This year’s project focuses on an collegiate campus facility. The application also requires a 250-word statement of the objectives and goals of the lighting design concept and two letters of recommendation from principal instructors at the student’s current design program. The submission is open to all second, third, fourth or fifth year undergraduate or graduate students in an accredited design program.

The deadline is March 16, 2012; the winner will be announced the week of April 30, 2012.

DOE Releases GATEWAY Report on LED Retrofit Lamps

The U.S. Department of Energy has published the final evaluation report from a retrofit of 32 track lights used to illuminate artwork in the lobby of the Bonneville Power Administration (BPA) headquarters building.

During the demonstration, 12W LED PAR38 lamps replaced 15W and 23W reflector compact fluorescent lamps that were installed in 2001, and comparisons were also made to original 90W halogen PAR38 reflector lamps replaced by the CFLs. This GATEWAY demonstration report provides an overview of project results including lighting quality, power quality, energy use, and life-cycle cost.

Key findings include:

  • Although both CFLs emit more light than the PAR38 LED replacement lamp, the narrower light distribution of the LED product concentrated the lumens on the artwork and minimized the amount of light striking the wall above the art.
  • Color temperature was around 2700K for all three lamps, but color quality improved with the LED lamping, from a color rendering index (CRI) of 82 for the CFL to a CRI of 93 for the LED. The LED lamp showed improved rendering of red tones in architectural finishes and artwork compared to the CFL products.
  • Power quality also improved with these LED lamps, although that is a function of the electronics design of these lamps, rather than a feature of LED lamps universally. Power factor increased from 0.50 or 0.55 for the incumbent CFLs, up to 0.94 for the LED lamp.
  • The study did not show rapid payback on the LED installation compared to the CFL products, considering the low electrical rates, the high cost of the LED lamps, and the fact that CFLs are already a fairly efficient light source. Life-cycle cost analysis done with more typical U.S. electric rates shows a payback time in the 7-8 year range compared to the 23W CFL.
