The recently released Wi-Fi standard, IEEE 802.11az enables more refined and accurate indoor location capabilities.
As technology manufacturers incorporate the new standard in various devices, it will enable buildings, including malls, arenas, and stadiums, to provide new wayfinding and tracking features. The previous standard yielded Wi-Fi location accuracy of 1-2 meters, while the new standard raises accuracy to less than 0.1 meter or about 4 inches.
Applications are expected to use this technology by:
- Providing more accurate indoor navigation. In a retail store, for example, a consumer could use an application to navigate through a store, as is used in vehicles to map a travel route, from the entrance to the desired product.
- Enablement of micro-targeting for retail and warehouse asset tracking. A store worker could use a mobile app to track products on shelves, in the stock room, and in a warehouse. A retailer could also leverage usage data from its customers’ shopping apps—such as their movements on the retail floor—to derive analytics and serve relevant ads to the user.
- Improved scalability will allow hundreds of devices to connect at the same time in dense environments, such as shopping malls, arenas, and stadiums where large numbers of users are actively co-locating with Wi-Fi simultaneously.
- Secure, authenticated, and private positioning. Proper authentication can be confirmed when you are within inches of two devices. This could be used, for example, to unlock an interior door via a smart device. Other applications could be the use of a smart device to make payment at the point of sale or using it to facilitate an ATM transaction.

USGBC Revises Energy Demand Response Credit
The US Green Building Council (USGBC) has updated the LEED Demand Response Pilot Credit. Originally launched in 2010, the revised and enhanced Demand Response Pilot Credit establishes guidelines that are anticipated to increase participation in automated energy demand response programs. LEED projects that satisfy the credit by demonstrating their ability to shift energy consumption by 10% of peak load demand will earn a point towards LEED certification when they participate in existing utility-sponsored demand response programs that meet guidelines established in the pilot credit. Additional points are available for projects that implement semi or fully automated demand response programs.(http://www.usgbc.org/ShowFile.aspx?DocumentID=9542)

New Sustainability Standard Addresses Disaster Resistance
To aid local governments to adopt high-performance green building codes, the Portland Cement Association (PCA) and the Institute for Business and Home Safety (IBHS) have developed High Performance Building Requirements for Sustainability 2.0. It includes the concepts in most other sustainability or green standards, while also enhancing disaster resistance.http://www.todaysfacilitymanager.com/facilityblog/2011/07/building-code-for-sustainable-construction-emphasizes-functional-resilience.html"A sustainable building with a higher degree of durability can decrease the amount of materials going to landfills and use of community resources when disasters occur,” says Steve Szoke, PCA director of codes and standards. “The PCA/IHBS ordinance provides mandatory requirements for increased resistance to natural disasters with the goals of reducing the number of destroyed buildings, protecting property, and saving human life."
