Introduction to Training Course for Re-Tuning Commercial Buildings (PDF 124KB

This slide presentation introduces the lead instructors and describes the purpose of the class.

Introduction to the Project (PDF 611KB)

This presentation provides background on the project, Battelle, the lead organization, the project objectives, and the general approach.

Building Personality (PDF 277KB)

This presentation section introduces the concept of the building personality, how it changes over the lifetime of a building, and how re-tuning gently adjusts parameters to achieve and maintain high-levels of performance over the building lifetime. The presentation introduces terminology and provides some examples of the beneficial impacts of building re-tuning.

Introduction to the Re-Tuning Process (PDF 95KB)

This section of the presentation explains the purpose of re-tuning, gives some examples of re-tuning actions, and defines the six primary steps of re-tuning.

Initial Data Collection (PDF 101KB)

This presentation discusses collection of basic building information to gain insight into the overall building design and its mechanical systems.

Pre-Re-Tuning Phase: Trend Data Collection and Analysis (PDF 1479KB)

This set of slides describes the second step of the re-tuning process, which is completed before the re-tuning visit to the building. It describes how to create a trend-data monitoring plan, gives an example of setting up trend logs in a building automation system, introduces a Battelle software tool for automatically generating key plots from the trend log data, and describes, with examples, how to identify opportunities for reducing energy consumption from the plots.

Building Walkdown (PDF 210KB)

This presentation takes the reader through the seven steps of the walking down the building, which is the third major step of the re-tuning process. It covers: reviewing mechanical and electrical prints, walking the building exterior, walking the interior of the building, walking down the roof, walking down the air handlers and plat area, and reviewing the building automation system front end. The objective of the walk down is to develop a better understanding of the building design, how the building is operating and special circumstances affecting the building operation.

Re-Tuning Controls and Systems (PDF 636KB)

This presentation focuses on the process of identifying and correcting operations problems, using the control system. It is guided by the findings of the trend-data analysis and the building walkdown, leading to implementation of corrective actions. The slides are organized into ten major areas of opportunity for improvement: scheduling, discharge-air-temperature control, discharge static pressure control, air-handler heating and cooling, air-handler outdoor fresh air makeup, air-handler economizer control, air dehumidification, zone conditioning, using meter profiles, and central plants.

Post-Tuning Phase and Energy Savings Analysis (PDF 122KB)

This presentation describes the reporting requirements of the project and introduces the method that Battelle will use to estimating the energy savings for each building.
