Sponsor: 7.5 Smart Building Systems, 1.4 Control Theory and Application
Chair: Michael Brambley, Ph.D., Fellow ASHRAE, PNNL, Richland, WAThe Internet of Things (IoT) is increasingly influencing our personal lives, businesses and infrastructures. It interconnects devices having embedded processing, sensors, data storage and physical capabilities, such as actuation. The interconnection of such devices enables the sharing of data and processing for mutual benefit. For buildings and their heating, ventilating and air-conditioning (HVAC) systems, the IoT can support improvements in monitoring of equipment and space conditions, energy management, supervisory control and participation in electric-utility demand response programs to mention a few. The presentations in this seminar provide examples of how the IoT can deliver improvements to building operation and control.

1. Smart Plug Enabled Intelligent Commercial Building Operations
Gang Wang, P.E., Member, University of Miami, Coral Gables, FL
This presentation introduces an integrated technology that utilizes smart plugs as occupancy sensors, along with low-cost virtual outdoor-air flow rate and thermal energy meters for energy efficient operations and detection of energy faults of air handling units (AHU) or rooftop units. The smart plug uses power measurements coupled with occupancy sensors to accurately infer occupancy. The virtual meters determine outdoor-air flow rate and thermal energy use in AHUs indirectly through control valve, outdoor air damper and fan operation variables, which are readily obtained. The technology integrates plug load systems with HVAC systems in commercial buildings to enhance energy performance.

2. Iot Technologies Make Buildings More Energy Efficient and Way Smarter
Xin (Sherry) Hu, Ph.D., P.E., Member, BriteThings, San Francisco, CA
IOT devices can measure energy use and other parameters accurately. Then the data will be pushed to cloud and analyzed using machine learning and artificial intelligence. The energy use is optimized with automatic and intelligent control strategies.

3. An Energy Balance Model for Detecting Anomalies in Residential Buildings
Brent Huchuk, ecobee, Toronto, ON, Canada
The advent of the smart thermostat as part of the connected home has changed the opportunity for study of residential buildings. For the first time, systems in the average home have been monitored for prolonged periods of time with continued and indefinite monitoring still happening. As such, researchers are no longer confined to only small archetype buildings or lab settings. This seminar reveals a case study on the determining of anomalies in the energy balance of a home. In particular, discussing the challenges of using these noncommissioned data sets across a variety of situations and discovering insights across the population.

4. Connected Appliances for the Win-Win!
Dane Christensen, Ph.D., Member, NREL, Golden, CO
This presentation discusses several recent R&D efforts at NREL which showcase opportunities for internet-connected residential HVAC and other "smart appliances" to cost-effectively provide mutual benefits to homeowners and utility systems. These include a Time-Of-Use study on HVAC interactions with the electric distribution system, a demonstration of residential equipment providing frequency regulation and a home energy management system which delivers reliable demand response without any reduction in homeowner comfort.
