This module sets the framework for benchmarking and conducting a comprehensive assessment of energy consumption in multifamily buildings. Participants roll their sleeves up right away as the group begins to interpret and analyze fuel bill data, and identify the major building systems, components, and usage patterns that impact energy consumption. Obtaining a building’s energy data is the first step in performance analysis; learning how to benchmark with this data to create a baseline prior to energy improvements, and to compare the building with similar structures, are among the key take-aways from this lively and interactive opening session.
This module introduces the core concepts, components, and terminology for the wide range of lighting technology typically found in multifamily buildings. Participants will also learn how to calculate minimum lighting levels for safety and maximum lighting densities for energy code compliance. Class exercises and discussions will help students learn how to determine the appropriateness of lighting component retrofits, replacements, or a full lighting system redesign. In addition, participants will learn about the latest in lighting control technology and how to select the right controls for each environment. Common issues around building operations and maintenance concerns for lighting systems will be addressed.
Participants in this module will learn how to identify critical components and construction techniques for common multifamily building foundation, wall and roof assemblies. This session focuses on how these building assemblies can function as a system to enhance a structure’s energy performance and what happens when they fail and create migration points for heat loss and moisture transfer. Participants review and apply important building science principles to make sound recommendations for envelope air sealing and insulation. During this process, participants engage with real-world case studies which demonstrate the interconnectedness between energy efficiency improvements and health and safety measures.
This module introduces participants to a range of common multifamily ventilation systems and prepares auditors to begin ventilation system diagnostics and assessments. Through case study examples, students learn how these systems are designed to operate, common causes of ventilation malfunctions, and the consequences for indoor air quality, heat loss, and building and mechanical system durability. Students will explore the diagnostic tools and procedures used to detect issues with system balancing, fan flow and operation, and duct work conditions. The session concludes with an analysis of different system retrofits and other methods for solving ventilation challenges.
Boilers and Burners is the first in a series of modules to get participants comfortable identifying and diagnosing common types of multifamily heating systems and their components. Whether attending training in AEA’s Bronx boiler lab or viewing the lab portion of this module on AEA’s interactive, high definition video platform from another location, participants will see and learn about a spectrum of boiler and burner combinations in real time and life size with the instructor, and they will learn how to apply this knowledge to auditing and construction managing multifamily projects. Participants will review and apply their knowledge of combustion science to sound combustion analysis techniques. By the end of this module, participants will come away with a tool box for diagnosing overall multifamily heating system efficiency and safety.
Participants in the steam systems module will gain knowledge of the basic steam heating cycle as well as various types of steam heat distribution and the key components of these systems. Participants will learn how to diagnose conditions such as unbalanced heat delivery and nuisance issues (e.g., water hammer) and apply solutions such as proper air venting and condensate return in both one and two-pipe steam systems. Proper control set points as well as successful energy management techniques are also covered in depth during this module.
Participants in this module will explore a variety of means for producing and distributing hot water for domestic use. This module will explore the advantages and disadvantages of common domestic hot water systems and the energy savings potential of each. Safety concerns for hot water use are emphasized through proper control set points and mixing valve operation. Participants will discuss successful strategies and methods for additional domestic hot water energy savings through fundamental water conservation techniques such as installing low flow/use devices, identifying and repairing leaks, water reuse, and occupant and building operations staff education.
During this module, participants will review common components and their functions in typical space cooling applications. Participants will build a fundamental understanding of the refrigeration cycle and the unique properties of common refrigerants as well as safe handling practices. This module will also explore the effects of an improper refrigerant charge, and techniques for evaluation in multiple systems. System-wide opportunities for efficiency improvements and well as system upgrades will be discussed.
Starting with rate analysis, and culminating with developing a quality assurance process, participants in this module will be guided through the necessary steps needed in order to build a quality energy model. This module includes a review of commonly used software applications and their limitations, typical indices used to evaluate building energy usage, and a discussion of justification and calibration of the model.
