EPA, FBI Warn of Dangerous, Fake R-22
WASHINGTON, D.C.—The U.S. Environmental Protection Agency (EPA) is cautioning homeowners, manufacturers of propane-based refrigerants, home improvement contractors and air-conditioning technicians of the safety hazards related to the use of propane in existing motor vehicle and home air-conditioning systems. EPA says a number of unapproved refrigerants with "22a" or "R-22a" in the name contain highly flammable hydrocarbons, such as propane. These refrigerants are being marketed to consumers seeking to recharge existing home and motor vehicle air-conditioning systems that were not designed to use propane or other flammable refrigerants. The FBI has joined EPA in issuing warnings and has launched an investigation into the sale of unapproved refrigerants. Specifically, it says the two agencies, along with the U.S. Department of Transportation—Office of Inspector General "are conducting an investigation into a flammable 'refrigerant' sold as Super-Freeze 22a, Super-Freeze12a, Super-Freeze 134a, Enviro-Safe 22a, and R134a."

Germany Leads, U.S. Lags in ACEEE Ranking of Most Energy-Efficient Economies
WASHINGTON, D.C.—Germany comes in first in a new ranking of the energy efficiencies of the world's major economies. According to the "2014 International Energy Efficiency Scorecard" by the American Council for an Energy-Efficient Economy (ACEEE), Germany is followed by Italy, the European Union as a whole, China, and France. The United States placed 13th of 16 economies ranked. The scorecard made its evaluations based on 31 categories across four groupings: those that track cross-cutting aspects of energy use at the national level, as well as the three sectors primarily responsible for energy consumption in economically developed countries—buildings, industry, and transportation. In its analysis, ACEEE lists four major opportunities for the U.S. to improve its energy efficiency: passing a national energy savings target, strengthening national model building energy codes, supporting education and training in the industrial sectors, and prioritizing energy efficiency in transportation spending.

June 2014 Was Warmest on Record
ASHEVILLE, N.C.—Last month was the Earth's warmest June since records began in 1880, according to data released July 21 by the National Oceanic and Atmospheric Administration (NOAA). It marked the second consecutive month in which the highest average monthly temperature was recorded. The average temperature over global land and ocean surfaces for June 2014 was 1.3°F (0.72°C) higher than the 20th-century average of 59.9°F (15.5°C). The United States experienced only its 33rd-warmest June on record.

Hopes for Global Carbon Trading Market Wane as Australia Pulls Out

WELLINGTON, New Zealand—The goal of a global carbon market to combat climate change, once touted to reach $2 trillion by 2020, received a major setback when Australia recently ended its planned carbon trading program, which would have been the third largest in the world. Australia's Emissions Trading Scheme (ETS) was to have started in 2015 and be linked with Europe's—the world's biggest market.This would have been the first direct connection between major emissions trading markets and a test case for possible links between potentially larger programs in China, Japan and the United States. "There's a realization that linking... is not going to happen within the 2020 timeframe," said Andrei Marcu, head of the Carbon Market Forum at the Centre for European Studies, referring to the year when a new global treaty on emissions reduction is expected to begin. Also, New Zealand announced that it would scrap its emissions trading program, one of the first to be established, effective in September. Currently, there is no worldwide carbon price. Each ETS operates under different rules and sets individual prices.

UK Store to be Powered by Food Waste
CANNOCK, UK—A Sainsbury’s store in West Midlands county will be the first retail outlet in the UK to come off the national grid and be powered entirely by food waste in a project announced this week. The store already sends all its food waste to the UK's largest anaerobic digestion plant. The facility turns food waste into bio-methane gas, which is then used to generate electricity, primarily for small-scale projects. However, this week, a 1.5 km (0.93 mile) cable has been installed, linking the plant to the nearby store. This allows the store to receive electricity directly from the plant.

New Strategic Plan Highlights Announcements at ASHRAE Annual Conference
Major actions taken at ASHRAE's 2014 Annual Conference included introduction of a new strategic plan, creation of a new indoor air quality alliance, and announcement of a milestone related to ASHRAE research program and Foundation. The new strategic plan’s four goals—connect, educate, extend, and adapt—serve as broad statements of what the organization most wants and expects to accomplish over the next several years. The newly formed Indoor Environment Quality Global Alliance seeks to serve as a global source for information, guidance and knowledge on indoor environmental quality. Also, it was announced that ASHRAE's 2013–14 RP campaign reached a new high of $2.35 million donated by members, chapters and companies.

Feature of the Week

Designing for IAQ In Natatoriums
By Randy C. Baxter
This article examines the effects of disinfectant by-products on indoor swimming pool air quality and to propose practical methods for mitigating their impact in conventional (recreational and competition) indoor pools. It notes common strategies to improve indoor pool air quality. However, the author advocates a less common strategy: source capture and exhaust of trichloramine vapor at water level.

Insulation From Dow Corning
MIDLAND, Mich.—The Dow Corning HPI-1000 Building Insulation Blanket offers improved thermal resistance as compared to conventional insulation products. Its thin profile, superb flexibility and compression resistance allow for thermal protection in hard-to-insulate spaces while eliminating the need for bulky or messy insulation in tight areas of a building. The product is hydrophobic, fire resistant and does not settle over time.

Airflow Meters From Sierra Instruments
MONTEREY, Calif.—Sierra Instruments offers the QuadraTherm 640i/780i precision airflow meters. The four-sensor meters measure all thermal heat transfers occurring and works with the company's proprietary qTherm algorithm set to calculate thermal dispersion in a fraction of a second for each mass flow data point. The instrument measures, then calculates stem conduction and all other unwanted heat loss components, subtracts them out, and then computes gas mass flow rate from the remaining forced convection (gas mass flow) component. The qTherm technology also enables the meters to change gas and pipe size settings in the field.
