Over the past two decades, UNL’s Energy Use Index has decreased nearly 40%, while enrollment and research funding increased significantly. One of the primary factors influencing this is the high degree of connectivity of our education and research buildings. For 30+ years, we have used a “home grown” DDC building automation system. Now in its 3rd generation, this BAS has given UNL the flexibility to easily add new features and control logic, and the relatively low installation costs allow multi-point controllers in almost every room. In addition to system control and energy optimization, the BAS collects and analyzes data for planned and predictive maintenance, utility metering with smart response, integration with the Utility Plant SCADA system, and provides a gateway to the Fault Detection and Diagnostics system which now monitors about 50% of the equipment on campus. We intend to review the big-data capabilities of these integrated systems and provide practical illustrations of how they have resulted in energy and operating savings.

Bharathan Balaji Research Scientist, Amazon AI Labs
Bharathan Balaji is a Research Scientist in Amazon AI Labs, where he works on reinforcement learning services and applications. He did his PhD at University of California, San Diego, where he developed smart buildings applications such as personalized thermostat control, fault detection and occupancy based control. He also helped develop the Brick ontology which is being adopted as an industry standard.
As buildings work towards reducing energy demands, and improved interaction with the electric grid, while maintaining a both thermally and visually comfortable environment for occupants, fenestrations are a key influential component in this effort. Fenestrations allow for natural daylight and outdoor views, but also represent the least thermally efficient portion of the building envelope, as well as a source of unwanted discomfort glare and direct sunlight. A multi-layered, dynamically-operated fenestration system that can be installed in new buildings or retrofitted for an existing building can help address building energy use and occupant comfort needs under a diverse range of climate conditions.

University of Colorado Professor and NREL Scientist Gregor Henze is leading a research effort as part of DOE’s ARPA-E Saving Energy Nationwide in Structures with Occupancy Recognition (SENSOR) Program. SENSOR intents to develop a new class of sensor systems that can significantly increase energy savings by reducing demand for heating and cooling in residential and commercial buildings. The University of Colorado Boulder and its partners are developing an occupancy detection system employing a wirelessly powered sensor network that communicates using radio-frequency identification (RFID) related technology. The sensors use privacy-preserving microphones and low-resolution cameras to detect human presence, relaying the information back to a central hub that also monitors patterns of activity in the home’s electricity use. Because the sensor system can be powered wirelessly, it can be deployed without costly and invasive rewiring. The sensor data is combined in computationally efficient ways to enable high accuracy human presence detection. This seminar will introduce the project and present initial results.

To quantify the deep heating ventilation and air-conditioning (HVAC) energy saving potential from emerging occupancy sensing technologies in commercial and residential buildings, we propose to design a novel testing and validation protocol with an eight-level diversity and simulation suite. We will investigate various types of occupancy sensors (e.g., human presence sensing, people counting, CO2 sensors) for detection failure rates and HVAC energy saving potential associated with occupancy sensor-driven control in a wide range of real-world applications. This talk will give an overview of this interdisciplinary effort that integrates advanced technologies from mechanical, electrical and computer engineering; statistical data analytics; building energy simulation and controls to provide a solution to complex sensor-driven cyber-physical systems in smart buildings.

Perspectives and framework for smart (intelligent) buildings from an HVAC manufacturer will be shared. The presentation will review the converging mega trends driving smart buildings including the connectivity/IoT/sensors/controls/automation enablers, the building operational and sustainability needs, the desire for grid interactions, the users/stakeholders values desirability, cost effectiveness and barriers for mass adoption.
The scope of smart buildings will also be discussed including the degree of ‘smart’ from the stakeholder’s viewpoint depending whether they are the tenants, building owners, service contractors, utility providers, the manufacturers, or the government, and whether the focus is on comfort, safety, environment health, energy, or operational productivity, and whether the application is Residential or Commercial buildings and whether they are new or existing buildings.
The eco-system architecture layers will be also reviewed regarding the breadth and depth of ‘smartness’ from an integration standpoint ranging from the grid, to the building BMS, to the building systems (HVAC/Lighting/plug loads), and subsystems/components. Can a building be smart without its sublevels be smart and connected ? State of smart buildings R&D activities will also be reviewed across various organizations including government national labs, universities, ASHRAE, manufacturers, etc. hopefully to identify gaps and foster increased collaboration.

This talk will provide an overview of the U.S. Department of Energy’s Building Technologies Office R&D strategy and energy savings goals for smart building technologies. The portfolio focuses on developments in managing multiple building subsystems (e.g., HVAC, refrigeration, and lighting) at the whole-building level; executing more complex strategies over longer temporal periods (e.g., hours and days rather than minutes) and at multiple spatial scales (e.g., occupant, zone, whole-building, campus); incorporating diagnostics, predictions (e.g., occupancy patterns, weather forecasts) and prescriptions along with current state information; and employing optimization techniques rather than rules. Recent efforts in the development of testing frameworks and procedures, along with curated datasets to support the R&D community at-large through common baselines to evaluate performance improvements and encourage additional innovation in advanced analytics and control strategies, will also be discussed
