Seminar 21: Automated Fault Detection and Diagnostics Methods for Building HVAC Systems
Room: JW Marriott Tampa Water Street, Tampa Bay 2
Summary: Automated fault detection and diagnosis (AFDD) for HVAC systems in buildings detect and identify operational faults based on the analysis of measured system behaviors. AFDD is critical in achieving the goal of building energy efficiency, reducing or eliminating energy waste in buildings caused by operational faults, and ensuring the persistence of building commissioning. This seminar presents new AFDD methods and research development for HVAC systems including functional performance test-based, inverse model-based, and evolving learning-based AFDD methods. The seminar also presents AFDD testing results and lessons learned based on the implementation of the new AFDD methods into several existing buildings.

Seminar 26: Integrating Data-driven and Physics-based Modeling Approaches for Advanced Research in the Built Environment
Room: JW Marriott Tampa Water Street, Tampa Bay 7
Summary: Data-driven and physics-based models are commonly used for predicting building performance. Physics-based models require detailed knowledge of building characteristics and HVAC systems. Substantial efforts are needed to create and calibrate the models. A data-driven approach does not require detailed information on building characteristics or system specifications. However, data-driven models are sensitive to the amount of training data, data accuracy, and the operating conditions under which the data were collected. A hybrid modeling approach integrating data-driven and physics-based models can be flexible and efficient. We demonstrate the hybrid modeling approach through urban system modeling, model predictive controls and indoor greenery systems.

Seminar 31: Field Performance of Occupancy-based HVAC Control in Commercial Buildings: Demonstration Results from ARPA-E SENSOR (Saving Energy Nationwide in Structures with Occupancy Recognition) Category D Teams
Room: JW Marriott Tampa Water Street, Tampa Bay 6
Summary: About 13% of all energy produced in the United States today is used to heat, cool, and ventilate buildings. Furthermore, 37% of all energy used by commercial buildings goes toward HVAC—even greater for residences, at 40%. Much of this energy is wasted, being used when buildings are unoccupied or occupied well below the maximum levels for which they are designed. Occupancy-based HVAC control has the significant energy saving potential. This seminar covers field testing results of occupancy-based HVAC controls in commercial buildings from ARPA-E SENSOR (Saving Energy Nationwide in Structures with Occupancy Recognition) Category D Teams.

Seminar 38: Connected Communities: Grid Interactivity, Energy resilience and Decarbonization
Room: JW Marriott Tampa Water Street, Tampa Bay 7
Summary: Connected communities, consisting of buildings communicating with the electric power grid and shared community resources, such as a photovoltaic generation and/or storage systems, can flexibly control loads to maximize energy efficiency, minimize energy costs, increase energy resiliency and contribute to decarbonization, while providing services to the power grid. The first presentation in this seminar shows how behind-the-meter energy resources such as flexible loads can mitigate the variability of distributed renewable electricity generation. The second presents how the coordination of the power demand of end use devices in two smart neighborhoods optimizes energy consumption based on a utility signal.

Seminar 49: Learned from BAS Data: The Most Common Operational Problems in HVAC Systems, and the Energy Savings from Fixing Them
Room: JW Marriott Tampa Water Street, Tampa Bay 2
Summary: Recent large-scale projects have analyzed BAS and fault diagnostic data from over 1500 buildings in the US, to understand what operational faults are the most commonly occurring, how persistent the faults are, and their impacts on building performance. One study examined monitoring data from over 60,000 unique pieces of equipment (air-handling units, VAV boxes, and rooftop units) over 12-24 months of operation to gather information. Another study looked at 151 buildings, and implemented corrective action in 69 of them, to assess energy saving potential. This seminar presents the summarized results of these landmark studies.

Seminar 70: Flexible Building Equipment Performance Verification using Hardware-in-the-Loop Testbeds
Room: JW Marriott Tampa Water Street, Tampa Bay 2
Summary: Flexible electricity loads provided by buildings help to create a resilient and reliable power grid while making electricity cleaner and more affordable. However, there are limited public data sets with high resolution that can help researchers and industry to understand building load flexibility. This seminar introduces three on-going projects funded by the U.S. DOE seeking to develop publicly available datasets that measure the performance of energy efficient building technologies and control systems to provide grid services, using three different hardware‐in‐the‐loop (HIL) test methods. The three HIL testbeds verify the building equipment’s load flexibility, while considering occupants’ interactions with the buildings.
