Newly Approved LEED v4 Set for November Launch
WASHINGTON—The U.S. Green Building Council (USGBC) has announced that its membership has voted to adopt LEED v4, the next update to the popular "green" building rating system. The full LEED v4 program will be unveiled at the Greenbuild International Conference & Expo, Nov. 20–22 in Philadelphia. USGBC will present a suite of webinars to educate potential users on the new program beginning later this summer. "This newest version of LEED challenges the market to make the next leap toward better, cleaner, healthier buildings," said Scot Horst, senior vice president of LEED, USGBC. "I am confident that people will also notice the improved usability of the system with an improved documentation process and more resources and tools to assist and support positive action." USGBC says there are more than 100 projects pursuing certification through the LEED v4 beta program.

Common Devices Consume Too Much Energy, Says ACEEE Report
WASHINGTON—There are more than two billion common electronic devices and equipment in U.S. homes and businesses. Collectively, they consume more energy each year than many large countries do to power their entire economies, according to a new report from the American Council for an Energy-Efficient Economy (ACEEE). Household devices, such as TVs, computers, and ceiling fans, and commercial equipment, such as elevators, icemakers, and MRI machines, use 7.8 quadrillion Btus (quads) each year, which is more than the primary energy use of some 200 countries. However, the report found room for improvement for such devices, referred to as miscellaneous energy loads (MELs) because they do not fit into traditional energy-use categories such as HVAC&R or lighting. The report found that the devices could be made to use 40% to 50% less energy with existing technology.

Heat Wave in Western U.S. Tests Power Grids
FOLSOM, Calif.—An ongoing heat wave in the western U.S. is the first major test of summer's spiking energy demand. Daily temperatures above 100°F (38°C) are occurring in states such as Arizona, California, Nevada and Utah. However, so far the power grid seems to be passing the test. Better technology and communications are responsible for that. However, utilities are still on high alert, particularly in California. The California Independent System Operator, which controls most of the state's power grid, issued a so-called "flex alert" across northern California this week. Consumers were asked to reduce their energy use between noon and 7 p.m., when demand for air conditioning is at its highest. Utilities also recommend turning off unnecessary lights, postponing major appliance use until after 6 p.m., and turning air conditioners up to 78°F (26°C), or using a fan instead. Those actions can generate savings of 1,000 MW statewide, enough electricity to power 1 million households, according to the California Independent System Operator.

EPA Warns Against Using Flammable R-22 Substitutes in Residential AC
WASHINGTON—The U.S. Environmental Protection Agency (EPA) is warning homeowners, propane manufacturers and sellers, home improvement contractors and air-conditioning technicians of potential safety hazards related to the use of propane or other unapproved refrigerants in home air-conditioning systems due to the refrigerants' fire and explosion risks. EPA is investigating instances where propane has been marketed and used as a substitute for R-22 (HCFC-22), a refrigerant that is widely used in home air-conditioning systems. EPA has not approved the use of propane refrigerant or other hydrocarbon refrigerants in any type of air conditioner. EPA has only approved the use of propane as a substitute refrigerant for R-22 in industrial process refrigeration systems and in new, stand-alone retail food refrigerators and freezers that are specifically designed to use flammable hydrocarbon refrigerants.

Google to Build 1,000-ft Long 'Groundscraper' in London
LONDON—Google has unveiled designs for its new UK headquarters, which will be longer than the Shard, the UK's tallest building, is tall. The 1,000 ft (330 m) long "groundscraper" will house all of Google's thousands of London staffers under one roof when completed in 2016. The 1 million ft2 (93 000 m2) building is expected to feature a climbing wall between floors and rooftop gardens. The entire site is expected to include a 20,000 ft2 (1860 m2) area for bike parking.

Feature of the Week

Demand-Controlled Ventilation for Commercial Kitchens
By Derek Schrock, Member ASHRAE; Jimmy Sandusky, Associate Member ASHRAE; and Andrey Livchak, Ph.D., Member ASHRAE
According to the authors, commercial kitchen demand-controlled ventilation (DCV) systems can offer great energy savings to the end user when properly implemented. Care should be taken to ensure the proper DCV system and sensor type are selected for a given appliance lineup. This article presents results of tests to compare performance of DCV systems that use temperature sensors only to those that incorporate cooking activity and temperature sensors. It also discusses possible future applications of DCV systems.
