Sleeping in Cooler Temps Could Improve Health, Says Study
NEW YORK—New research has found that lowering the thermostat while sleeping has potential health benefits. According to a National Institutes of Health study, sleeping in a cool, 66°F (19°C) room can increase metabolism, aid weight loss and improve insulin sensitivity. The study, published in Diabetes, the journal of the American Diabetes Association, involved monitoring healthy young men who slept in climate-controlled facilities for four months. The lower temperatures increased the amounts of "brown fat"—called "good" fat for its ability to burn calories and take sugar out of the bloodstream—in the subjects' bodies.

Google Offering $1 Million for Laptop-Sized Inverter
MOUNTAIN VIEW, Calif.—Google is offering a $1 million prize for a breakthrough that would make renewable energy technologies more viable for everyday uses. Google has teamed with the Institute of Electrical and Electronic Engineers (IEEE) to promote a "Littlebox Challenge" by offering the reward for the best design for a device no bigger than a laptop that can efficiently convert dc from solar panels and batteries to ac for business and home use. The challenge is to shrink power inverters to about a tenth of their present size. "There will be obstacles to overcome; like the conventional wisdom of engineering," said Eric Raymond of the Google Green Team in an online post announcing the challenge. "But whoever gets it done will help change the future of electricity."

AHRI Petitions for Court Review of DOE Final Rule on Freezers, Coolers
ARLINGTON, Va.— The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) recently filed a petition for review in the U.S. Court of Appeals for the 5th Circuit of the U.S. Department of Energy’s (DOE) final rule issued on June 3, regarding energy conservation standards for commercial walk-in coolers and freezers. The rule establishes minimum energy efficiency standards expressed in terms of annual walk-in energy factor for various equipment classes. AHRI says that in the final rule, DOE set efficiency levels above DOE’s own determination of what the maximum technology is for some types of this equipment.

ICC to Discuss Report Showing 1.6 Million Americans Lack Indoor Plumbing
WASHINGTON, D.C.—The International Code Council (ICC) will host a teleconference at 1 p.m. EDT on Aug. 25 to discuss the basic sanitation needs of the reported 1.6 million Americans in 630,000 households that do not have indoor plumbing. The data from the U.S. Census Bureau found that a high number of those without indoor plumbing reside on Native American tribal lands, and in Alabama, Alaska, Kentucky, South Dakota and West Virginia. Teleconference panelists and participants will discuss the extent of the situation, examine the range of causes and offer solutions where possible. ICC expects to issue a statement of findings with a call to action to address who can be helped and how.

Thinking an Odor Is Harmful Could Trigger Asthma Symptoms
PHILADELPHIA—For patients with asthma, just believing an odor is potentially harmful is enough to trigger airway inflammation for at least 24 hours, a new study has found. "Asthmatics often are anxious about scents and fragrances. When we expect that an odor is harmful, our bodies react as if that odor is indeed harmful," said study author Cristina Jaen, a physiologist at Monell Chemical Senses Center in Philadelphia. The study is published in the Journal of Psychosomatic Research.

Residential Solar Is On the Rise
SEATTLE—Going solar is expensive, but a confluence of plummeting equipment prices, rising utility bills, new financing programs and federal, state, and local incentives are encouraging homeowners across the United States to put photovoltaic panels on their roofs. In 2013, 792 MW of solar capacity was installed on homes. That figure is expected to increase 61% in 2014 and another 53% in 2015, according to the Solar Energy Industries Association. A megawatt of solar capacity is typically enough to power 200 average U.S. homes.

ASHRAE Offers Online Course On Building Demand Response And Smart Grid
A new ASHRAE Learning Institute course, "Building Demand Response and the Coming Smart Grid," addresses new technologies and design concepts that are leading the way to how buildings and their systems will interact with the coming smart electrical grid. According to course instructor Tom Lawrence, Member ASHRAE, the course is particularly relevant because ANSI/ASHRAE/USGBC/IES Standard 189.1-2011, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings, includes a requirement that the building be designed to have the capability of reducing peak electrical demand through active controls or other load-shifting measures by 10% of the building’s projected peak demand. Similar requirements or incentives for demand response management are contained in the International Green Construction Code and with the latest version of LEED. The course will be held Sept 29. It is part of the ALI Fall Online series. There are 13 ASHRAE Learning Institute fall online courses scheduled. Course participants earn continuing education credits and qualify for Professional Development Hours for each course completed.

Used Filters and Indoor Air Quality
By Gabriel Bekö, Ph.D.
The presence of used filters in a ventilation system can have an adverse impact on perceived air quality, Sick Building Syndrome symptoms, and performance of office work. This article discusses research into this problem. Possible mechanisms responsible for the emission of noxious compounds from ventilation filters are described. Also, the economic impact of polluting ventilation filters and possible engineering solutions are discussed.
