IAQA to Become Part of ASHRAE
ASHRAE and the Indoor Air Quality Association (IAQA) have agreed in principle to join forces and combine resources to improve indoor air quality in the built environment. Pending a three- to six-month period of due diligence, IAQA will become part of the ASHRAE organization while maintaining its own brand and board of directors. IAQA will operate independently within ASHRAE’s organizational structure. Plans call for IAQA headquarters to relocate from Rockville, Md., to ASHRAE’s headquarters in Atlanta. The agreement was reached between the leadership of both associations and confirmed at the 2014 ASHRAE Annual Conference earlier this month. “This merger is beneficial to both ASHRAE and IAQA in that it strengthens the programs and services of both organizations,” said ASHRAE president Tom Phoenix. "The work of IAQA complements the work of ASHRAE in its standards, research, publications and educational offerings."

EPA Proposes to Prohibit Some Uses of HFCs
WASHINGTON, D.C.—The U.S. Environmental Protection Agency (EPA) is proposing to limit the use of various hydrofluorocarbons (HFCs) that are currently listed as acceptable alternatives to ozone-depleting substances. The agency said the proposed rule would prohibit certain uses of chemicals that have high global warming potential. For example, the proposed rule would list HFC-134a, the most abundant HFC, as unacceptable for use in motor vehicle air-conditioning systems in new light-duty vehicles beginning in model year 2021 and unacceptable for use in new, stand-alone retail food refrigeration equipment and new vending machines as of Jan. 1, 2016. Also, EPA is proposing to no longer allow the use of HFC-125 in aerosol propellants and to disallow the use of various refrigerant blends in motor vehicle air-conditioning systems. The proposed rule is currently in a 60-day public comment period.

Dubai Calls on Occupants to Report IAQ Problems
DUBAI, United Arab Emirates—The Public Health and Safety Department of Dubai Municipality has embarked on an effort to raise awareness of indoor air quality in the emirate. Residents and employees that experience poor indoor air quality at home or in offices can report it to the department by calling a dedicated hotline. The effort includes aggressive enforcement of a 2003 local order that calls for "fulfillment (by the building) of the health and environmental conditions and safety requirements which ensure protection of health and safety of its residents, and maintain its interior and surrounding environment," said Raed Al Marzouqi, head of the Occupational Health and Safety Section at the Department. With the awareness program, the Department aims to increase the percentage of buildings complying with indoor air quality standards to 70%. In addition to occupant reporting, there is a call for increased inspection and monitoring of IAQ, ventilation and air-conditioning systems.

Emerging Technologies Leading to More Efficient Buildings, Say Industry Leaders

WASHINGTON, D.C.—Emerging and maturing technologies such as natural gas, variable speed air conditioning, solar power, combined heat and power (CHP), and energy storage are reducing current energy use and harbor even greater potential to improve building energy efficiency, both individually and in the short term. This was the consensus of participants in the recent 21st Danfoss EnVisioneering Symposium. The event brought together executives in HVAC and related industries, as well as leaders in research and business, to discuss the future of energy efficiency in new and retrofit buildings. “With much higher building efficiencies and onsite photovoltaics, combined heat and power generation, and cleaner fuel, we will no longer be as dependent on massive coal-fired power plants,” said Robert Wilkins, Danfoss' vice president of public affairs. The optimization of the efficiency of individual technologies is leading to increased popularity of a whole building systems approach. John Galyen, president, Danfoss North America, said "While converging technologies are creating a trigger point for change, these changes will define a new utility model of the future. And, that reality would require a change in the mindset of everyone from the equipment manufacturers to the building owners and maintenance professionals to the electric and natural gas utilities.”

Energy Bills Lowest in Colorado, Highest in Hawaii, Says New Ranking
WASHINGTON, D.C.—Colorado is the least "energy expensive" state in the U.S., followed by Washington State, according to a new report. The report by website WalletHub uses "six key metrics to rank the states (and the District of Columbia) according to their tendency to produce the highest or lowest monthly energy bills." Hawaii has the highest monthly energy cost, with Mississippi being the most expensive in the continental U.S. The rankings took into account the price and consumption of residential electricity and the price of vehicle fuel. Lower prices don’t always mean lower costs, WalletHub said. Consumption is a key determinant in the total energy bill. In places with high summer temperatures but cheaper electricity such as southern Louisiana, households might end up with higher out-of-pocket costs than those in energy-expensive northern California, where the temperate climate keeps heating and cooling units idle most of the year. WalletHub says in the United States, 7.1% of the average consumer’s total income is spent on energy costs.

Venezuela Airport's 'Breathing Tax' to Pay for Ozone System
CARACAS, Venezuela—A Venezuelan airport is charging travelers for the cost of breathing clean air with a technology that has been questioned by ASHRAE. As of this month, travelers who depart the International Airport of Maiquetia Simon Bolivar, just north of Caracas, will have to pay 127 bolivars (slightly more than $20) to cover the cost of the airport's new ozonation system. The system uses ozone to purify the airport's air, according to a statement from Venezuela's Ministry of Water and Air Transport. The government says that the technology eliminates bacterial growth and protects the health of travelers by sanitizing the building. However, the ASHRAE Environmental Health Committee has found that "introduction of ozone to indoor spaces should be reduced to ALARA (as low as reasonably achievable) levels." With tickets out of the country already expensive and scarce because of Venezuela's economic crisis, many on social media have responded to the tax with outrage. A Caracas radio host tweeted "Could you explain to me the ozone thing in Maiquetia? The toilets don't have water, the air-con is broken, there are stray dogs inside the airport, but there's ozone?"

ASHRAE Joins IEQ Alliance
ASHRAE is part of a newly formed alliance that aims to serve as a global source for information, guidance and knowledge on indoor environmental quality. A memorandum of understanding creating the Indoor Environment Quality Global Alliance was signed at the recent 2014 ASHRAE Annual Conference in Seattle. Other groups joining the Alliance are the American Industrial Hygiene Association (AIHA), Air Infiltration and Ventilation Centre (AIVC), the Air & Waste Management Association (A&WMA), the Indoor Air Quality Association (IAQA) and the Federation of European Heating and Air-Conditioning Associations (REHVA).

Feature of the Week

Optimizing Building Controls During Commissioning
By Michael A. Hatton, Associate Member ASHRAE; Tim Sullivan, P.E., Member ASHRAE; and Larry Newlands
According to the authors, building owners, contractors, design engineers, and commissioning teams expend huge efforts and project resources on verifying component compatibility with control specifications, basic on/off control features, and performance at peak design conditions. However, these systems often are not optimized for a typical operating condition. This article focuses on health-care facilities, but its guidance is viable for many types of facilities.
