Understand how to conduct a thorough building "walk down" for a re-tuning effort. Purpose being to develop a general impression of: overall building condition, overall building design, HVAC system design. Also to collect some basic data on the building systems at a level of detail greater than the initial data collection and to confirm/verify issues or problems identified through trend analysis.

The primary audience for this instructor manual is the person who will be teaching the re-tuning course. In addition, community college instructors, retro-commissioning training providers and building operator training providers may find value in the material presented in this instructor manual as well. The purpose of this course is to help building operations staff to learn how to operate buildings more efficiently, reduce operating cost and provide energy savings. The knowledge and skills learned through the training will be highly valued by organizations and companies seeking to improve the performance of
their buildings.

The intent of this user guide is to provide a description of the functionality of the Energy Charting and Metrics plus Building Re-tuning and Measurement and Verification (ECAM+) tool. ECAM+ facilitates the charting and analysis of energy use and point-level data from utility meters, building automation systems (BASs), and data loggers. This document describes the tool’s general functions and features, including installation, use, guidance, and limitations.The Energy Charting and Metrics Tool (ECAM) is an add-on for Microsoft Excel® which was developed to facilitate analysis of data from building (energy and other data). Key features of ECAM+ include the creation of charts to help re-tuning.

Re-tuning focuses on a number of commonly occurring operational problems in buildings. These guides, through examples, provide details on how to detect good (normal) and bad (abnormal) operations. The purpose of the air-handling unit (AHU) heating and cooling control guide is to show, through examples of good and bad operations, how AHU heating and cooling can be efficiently controlled.

Re-tuning focuses on a number of commonly occurring operational problems in buildings. These guides, through examples, provide details on how to detect good (normal) and bad (abnormal) operations. The purpose of the air-handling unit (AHU) minimum outdoor-air operation control guide is to show, through examples of good and bad operations, how AHU outdoor-air operations can be efficiently controlled.

Re-tuning focuses on a number of commonly occurring operational problems in buildings. These guides, through examples, provide details on how to detect good (normal) and bad (abnormal) operations. The purpose of the air-handling unit (AHU) static pressure control guide is to show, through examples of good and bad operations, how the static pressure can be efficiently controlled.
