Occupant Behavior Driven Smart Building Controls

In the US, people spend 87% of their time in buildings. Understanding dynamic occupant presence and thermal comfort needs is crucial to ensuring that building design and operations provide healthy and productive living and working environments. Occupant behavior is becoming a leading factor for building energy use, but there are challenges to studying occupant behaviors, as they are complex and ever changing. Privacy issues and the high cost of sensors can make data collection difficult. The constant changes in the built environment caused by occupant behavior also result in both physiological and psychological effects on the occupants.

Professor Bing Dong’s presentation covered various research projects related to behavior driven controls and optimization of smart and connected buildings, from behavior-driven individual building energy optimization to urban scale energy management, from equipment level optimal controls to large scale buildings-to-grid integration. Professor Dong concluded with a research vision on behavior-driven urban energy infrastructure planning and management within a smart and connected community. 

Steven VonDeak presented the people count sensor platform, Density, Inc. To put it simply — Density counts people. Understanding how many people are in a space helps organizations improve building performance by making them safer, more efficient and more productive. Density’s people counting system places a premium on three key functionalities: anonymity, accuracy, and real-time data availability. This real-time room occupancy provides insight for a variety of use cases including intelligent demand-controlled HVAC operation. Organized in 2014, Density has grown to a 50-person startup and their proprietary hardware/software system is all assembled, tested and packaged right in Syracuse, NY.

Lessons Learned from Monitoring and Re-Commissioning New York State’s Portfolio of CHP Systems

Combined heat and power (CHP) systems, or cogeneration, provide on-site electric power and thermal energy from a single system, eliminating waste and reducing greenhouse gas emissions. Conventional power plants use fuel to generate electricity but reject waste heat into the atmosphere. In contrast, CHP systems recover that waste heat and use it for industrial processes, to heat domestic hot water, and provide space heating and cooling.
 
This Research & Technology Forum featured fleet-level results for several CHP systems that have been installed under NYSERDA‘s CHP program. Specifically, Hugh Henderson, Principal Consultant at Frontier Energy, outlined the types of performance issues that have been found at specific sites, and shows how performance-monitoring and re-commissioning efforts have helped these CHP installations achieve their expected potential.

Faculty Fellows Research: Using Virtual Reality for Data Simulation

Syracuse University Professors Melissa Green and Amber Bartosh are collaborating on a project that attempts to use virtual reality software to create immersive data visualizations for architecture and engineering purposes.

We see alignments between what we’re trying to do in terms of data visualization. It’s not that crazy a pairing when you think about it from that standpoint.AMBER BARTOSH

Intellectual Collision Bartosh is an architect who uses virtual reality to visualize things like energy flows around people in a building. Green, a mechanical and aerospace engineer, seeks to use the same technology to visualize fluid flows, such as around fins in water. “We see alignments between what we’re trying to do in terms of data visualization,” says Bartosh. “It’s not that crazy a pairing when you think about it from that standpoint.”

Nuts and Bolts Advancements in digital modeling tools have dramatically increased the amount of spatial data relating to fluid dynamics flow visualization, and building energy systems. However, the two-dimensional systems typically used to represent this data usually oversimplify complex three-dimensional conditions. With initial funding from SyracuseCoE as part of the Faculty Fellows Program, followed by a CUSE Innovation Grant from Syracuse University, Bartosh and Green are working to make links among traditional architecture, engineering software, and virtual reality software to create immersive data visualizations.

Challenges It’s a difficult process. While it’s easy to represent a building visually, it’s more challenging to show how a building is going to perform in terms of thermal control or daylighting. “Those things are more difficult to convey because we’re not used to seeing that data in 3-D,” says Bartosh. “We can measure it and record it in charts or spreadsheets, but what we’re trying to do is bring that into this virtual environment, feeling like you’re walking through the real space with the temporal qualities specifically related to energy and flow that we are trying to visualize.”

Real-World Collaboration Bartosh is using projects from SyracuseCoE Partner firm Ashley McGraw Architects as test cases for data visualization methods to see if they help with communication. In turn, Ashley McGraw has integrated VR into its practice after seeing how the technology was being used by architecture faculty working at the SyracuseCoE Interactive Design and Visualization Lab (IDVL).

SyracuseCoE Impact Bartosh and Green are both SyracuseCoE Faculty Fellows working out of labs at SyracuseCoE headquarters. Green directs the Flow Visualization Lab, while Bartosh works out of the IDVL. SyracuseCoE funding allowed for the purchase of VR equipment used for their current project. “The space and resources we have here are fundamental to what we do,” Bartosh says.

Bottom Line The collaboration is an attempt to make data visualization a more streamlined process for each of their own labs and, ultimately, a feasible product transferable to other STEM and design disciplines.
