This workshop will highlight the advantages of re-tuning from energy savings and occupant comfort perspective, and provide insights into re-tuning principles and a practitioner's guide for how to apply the re-tuning approach. Several Federal Energy Management Program (FEMP) tools for conducting re-tuning will be introduced and an interactive walk-through of the Building Re-tuning Simulator tool will be conducted, orienting the participants to the features and layout of the tool and how to model re-tuning measures.
Nick Fernandez, Building Control Engineer, Pacific Northwest National Laboratory Read Bio
Nick received a Master's in mechanical engineering from the University of Maryland in 2008 at the Center for Environmental Energy Engineering. Throughout his 13-year career at PNNL, he has focused on research and project work on technical tasks, tools, and journal papers that solve problems through building energy simulation, typically involving the use of EnergyPlus. These efforts have had many applications, including but not limited to detailed models of specific commercial buildings, large-scale simulation of energy saving measures to determine national impact, commercial building energy codes, simulation of the thermal side of algae ponds and photobioreactors for biofuels production, simulation of a novel rooftop selective emittance cooling system, co-simulation of EnergyPlus and VOLTTRON for optimal dispatch of combined heat and power systems, and creation of the simulation backbone for a rooftop unit cost calculator tool. Nick is also the creator and lead developer of the Building Re-tuning Simulator, a standalone energy simulation tool, which streamlines the creation of an energy model from audit level data and details on control sequences, with a focus on quantifying savings from re-tuning measures and helping the user to optimize reset parameters and setpoints. The BRS is being converted to a Web tool hosted by FEMP for the purpose of efficiently evaluating the savings associated with Re-tuning measures for commercial buildings and also to serve as a Re-tuning training platform. Nick's other career focus has been performing Re-tuning evaluations. He is the project manager of two programs that identify and implement re-tuning measures in Federal office buildings and courthouses for GSA and is a technical lead for FEMP's Re-tuning Challenge.
Upon completion of this workshop, attendees will be able to:
- Identify FEMP tools for conducting re-tuning evaluations;
- Confirm a basic understanding and orientation of re-tuning concepts; and
- Participate in a walk-through of the new Building Re-tuning Simulator tool; and Identify how to start applying the Re-tuning approach.
