Construction Executive - September 2016 - 58

SPECIAL SECTION: CONSTRUCTION EXECUTIVE | SEPTEMBER 2016 CONSTRUCTION TECHNOLOGY 58 typically require data streaming to the server or the cloud for further analysis, which burdens the network with increased traffic and delays response times. Second, because a building's lighting infrastructure is designed for longer-term installation, smart sensors incorporated into the lighting system should be future proof (i.e., flexible and scalable to adapt to future enhancements and modifications). Third, given that lighting fixtures are ubiquitous across the building space, smart sensors must be low cost to afford wide deployment. Image-Based IoT Sensors for Smart Buildings Recent developments in sensing technologies address these challenges in an effective way. A new breed of smart sensors includes miniature image-based devices, running embedded analytics on a low-cost processor that can be incorporated into the lighting fixtures of a digital ceiling. Using imaging, the sensor captures detailed information about objects' and occupants' activity. Unlike most image-based solutions, all analytics are performed within the device, so only the processed data (actionable information) is passed to the network. This way, communication traffic is minimized and occupants' privacy is preserved. Low-cost, low-power embedded microprocessors keep costs down for contractors considering widespread sensor deployment. Smart sensors support a wide range of applications. * Space utilization management. Space utilization information enables commercial facility managers to better optimize the facility's layout for current and future needs. New smart sensors can track occupants' locations and movements, providing valuable real-time insight into how spaces are being used (or underused). * Energy savings. By counting the number of occupants in a given space, demand-controlled ventilation can be optimized to save energy and comply with industry standards and regulations. Incorporating the smart sensor into lighting fixtures yields a variety of unique insights on energy management and lighting usage. Data provided by the sensor can help determine how to optimally light a space while taking advantage of natural light, thereby saving energy. * Safety and security. The smart sensor can provide information for improving safety by detecting falling accidents and assisting in emergency building evacuations. Security access control can be enhanced by detecting events such as tailgating and loitering in pre-defined zones. In view of the ongoing transformation of the building automation industry, spearheaded by the IoT revolution, the lighting system is considered to be the most suitable infrastructure to carry on the smart building mission. A digital ceiling that uses smart sensors incorporated into lighting fixtures creates an affordable and scalable option for system providers, building owners and facility managers.
