These Weren’t the Droids We Were Looking For: Real Examples from Integrated Systems Testing (and other Imperial Cx Projects)
Mark Gelfo, PE, CxA, EMP, LEED Fellow, TLC Engineering Solutions
Why were there no EPO buttons on the garbage smashers on the Death Star? The Empire didn’t do Integrated Systems Testing!
This session will be a fun and somewhat terrifying look at numerous real-world examples of “deficiencies” found from numerous commissioning projects, with an emphasis on issues found during Integrated Systems Testing. Every picture has a story and a lesson learned…even if we weren’t looking for it when we found it.
What is Integrated System Testing (IST)? Simply put, it is the testing of all building systems together under multiple building conditions and event possibilities, including loss of power, fire alarm, storm events, and Rebel Alliance attacks. When we perform IST, we always find issues we weren’t looking for, and we will share some of those examples with you during this session.
- Understand what Integrated systems testing is and why it is an important part of the commissioning process.
- Know what a black-site test is, and why it is an important test for any new building.
- Apply lessons learned from our projects case study examples on their next commissioning project.

Unifying Data from Diverse Systems and Sources to Enable Whole-Building Analytics, FDD and KPI Analysis
Roger Quesnel, SkyFoundry
Today’s facilities are increasingly populated with smart devices and equipment systems. These systems come from a variety of manufacturers and communicate using a wide range of methods from field busses based on standard protocols i.e., BACnet, OPC UA, MODBUS and others, to webservices that offer a wide range of open, yet different APIs (Application Programming Interfaces).
The challenge for the commissioning professional is that they need the data from all, or most of, these systems in order to accomplish their job of ensuring proper operation of complex building systems. The effort required to connect to and acquire usable data from diverse systems is one of the major cost and complexity barriers to implementing cost effective MBCx and data-driven retro-commissioning.
Addressing this issue has led to a focus on software that can unify and normalize diverse data sources and act as an independent data service making the data available to any and all applications that need it via a standard, open interface. In this session we will provide an introduction to the concept of an IDL – independent data layer and discuss the factors involved in achieving the necessary functionality to acquire and normalize data to support real world applications.
- To identify key characteristics of an IDL.
- To identify different sources of data that can be used in the MBCx process.
- To understand the role of semantic data/tagging in normalizing data from different sources.
- To provide basic understanding of Project-Haystack as a data tagging standard.
Cx and Energy Professionals’ Funding Opportunities, and Decarbonization Basics, as Influenced by the Inflation Reduction Act
Carl Salas, PE, Salas O’Brien
Tim Gilbert, PE, CxA, EMP, Salas O’Brien
Today’s concerns about carbon and greenhouse gas are on the front page of every newspaper, and on the top of the agenda for most of the Fortune 500 (and other) companies. As a result, Cx and energy professionals can be greatly regarded, and rewarded, if they understand the carbon conversation within the framework of Cx and energy-related efforts. More importantly, there is funding associated with the Cx and energy efforts that result in direct savings of greenhouse gasses. This presentation reviews current definitions and metrics associated with climate change and greenhouse-gas. These definitions and metrics are then framed against the typical energy (and other) savings accomplished by Cx and energy professionals. And THESE savings are framed against available funding opportunities associated with the Inflation Reduction Act passed in 2022 in the United States. The attendee will leave with a clear understanding of the nexus between Cx/energy efforts and greenhouse gas, as well as associated funding opportunities.
- Understanding the carbon conversation within the Cx and Energy related business efforts.

Commissioning of Food Service Spaces: Overview, Challenges, and Lessons Learned
Brad Davis, PE, CxA, AECOM
Many of us give little though to where we will get our next meal, because . a quick meal is always nearby whether it’s a restaurant, café in an office building, lunchroom at a school, restaurant at a hotel, or coffee shop at the airport. Similarly, especially with large and complex building projects, it’s also common for little thought to be given to the systems that serve kitchen areas.Often time food prep areas are a small portion of a large building project. These spaces are often given little special treatment by contractors. Specialty contractors may be used for food prep equipment and specialty ventilation systems. However, the sub-contractors for the overall project are likely responsible for the supporting HVAC, electrical, plumbing, life safety systems and integration of those systems.
The commissioning process offers opportunities to help overcome the challenges that food service spaces present. Understanding common issues, attention to detail, and proper teamwork are key to delivering a building with a safe and functional food service space.
- Identify features of kitchen design and system requirements.
- Understand common approaches to installation of kitchen systems.
- Recognize common challenges of integrating kitchen and building systems
- Understand how use the Commissioning Process to streamline integration and testing of kitchen systems.

Commissioning Process for Federal Facilities: Case Studies of Varying Expectations
John W. Thompson, PE, CxA, RS&H
Per legislative mandate, Total Building Commissioning and the process of ensuring that a building’s performance meets or exceeds owner’s functional requirements and design intent is a required activity for all newly constructed federal buildings. Evolving Federal, State and Local mandates, in conjunction with voluntary, market-based standards, have transformed the Cx marketplace and created a paradigm shift in how to retain quality assurance in building performance.
What began as a tool to ensure that building owners get their money’s worth from design and construction professionals, commissioning is now known to be the most cost-effective measure available for reducing energy use, lowering costs and mitigating greenhouse gas emissions in buildings. A recent meta-analysis by Lawrence Berkeley National Laboratory found that Re/Retro-commissioning yields a median 16% energy savings with a payback time of 1.1 years, for a cash-on-cash return of 91%.
Despite the well-documented evidence, however, the purpose of LEED commissioning has been historically underutilized in federal new-build projects. In this presentation, case studies that followed LEED Fundamental and Enhanced Commissioning guidelines for newly built and renovated facilities for the Departments of Defense and Homeland Security will be reviewed and analyzed. Perceptions and expectations of the Cx process from the perspective of all stakeholders including owners, designers, contractors, and commissioning specialists will also be discussed.
The purpose is to illustrate that there are varying levels of agreement on “What Commissioning Is and Is Not.” The session will illustrate that LEED Commissioning does not establish the final boundaries and benefits for the overall Total Building Commissioning process. The potential energy conservation and utility cost-saving benefits that could be captured go beyond LEED and enhance our country’s goal of energy independence.
- Understand Federal Requirements for Total Building Commissioning.
- Know the five phases of the commissioning process.
- See how stakeholder expectations of a commissioned facility often vary and may conflict.
- Reconcile expectation issues to the benefit and satisfaction of the owner.
The Benefits of MBCx from Day 0
Matt Herbster, Kite Pharma
Dotty Hage, MelRok
Building commissioning services have been an accepted practice to validate, document, and ensure compliance with the design intent for a facility’s HVAC mechanical systems. However, post-construction warranty phase commissioning is not necessarily a standard nor is it a requirement for Cx service providers. This in turn leaves a void in the handover from commissioning to facilities’ operations and maintenance (O&M). The disconnect between Cx and O&M puts a strain on the facilities’ HVAC staff trying to ensure operations based on the design intent. Ongoing Monitoring-Based Commissioning (MBCx) bridges the disconnect between design intent, Cx, and O&M.
In this case study, an ongoing MBCx program was implemented on a brand-new, newly commissioned, 300,000 ft2 pharmaceutical facility. Even though the facility was newly commissioned, over 85 faults and opportunities were found. Anomalies were found in a variety of HVAC systems including the central plant, air handlers, and the terminal units. The most serious involved the chiller plant where a significant refrigerant leak from one of three chillers was identified.
The type of anomalies highlighted by the ongoing MBCx included sequence of operation requirements not being met (23% of all faults), poor configuration of terminal units (45%), TAB requirements not met (14%), and excessive heating (9%), among others.
These findings are surprising given that the facility was newly commissioned and handed over to the owner. Thus, we believe that ongoing MBCx is not only important in warranty or post construction phase, but is also important during the commissioning phase.
- Understand the benefit of implementing a MBCx program during initial commissioning.
- Understand real-world examples of the benefit of MBCx.
- Understand the gaps in the current hand-off process between Cx and operations & maintenance
Test, Adjust & Balance; Lessons Learned for Engineers, Cx & Energy Providers
Jim Hall, PE, TBE, CxA, System Dynamics, Inc.
Testing, Adjusting and Balancing (TAB) is a process utilized for heating, ventilating, and air-conditioning (HVAC) and related systems to optimize system performance and prove that design intent has been met. Equipment selection, improper and proper use of TAB instrumentation, system layout for testing and maintenance access, document review strategies, defining meaningful and useful TAB data, incorporating new industry product technologies, and project scheduling issues are all common challenges that a TAB provider encounters. This article offers solutions and ideas to help overcome these challenges, for the benefit of the design professional, construction team, commissioning provider and ultimately the building owner.
- Understand the proper use, application, and limitations of the TAB instrumentation.
- Understand what is accurate, useful and meaningful data that is obtained in the field vs. laboratory data for use on their project.

The Power of RCx + MBCx: How to Sustain Energy Savings
Clifford Alberts, PE, AESC, Inc.
Susan Freed, CEM, LEED AP, County of San Diego
The County of San Diego is a leader in California in terms of implementing progressive energy and sustainability goals and programs. In 2017 the county published a net zero energy plan to formalize aggressive energy savings goals. The plan served as a catalyst to fund a series of RCx projects which identified many opportunities for low cost/high savings measures. The nature of the projects also revealed the need for an MBCx program to protect those energy savings from drift and human error. The RCx projects, MBCx pilot and MBCx program have achieved significant, persistent, energy savings as well as lessons learned on how to make monitoring a standard practice.
- Gain insight into the planning, piloting and goal setting of a government based MBCx program

Commissioning HVAC Systems for Sustainable Indoor Air Quality
Erik Malmstrom, SafeTraces
Jeffrey Michael, P.E., CEM, Setty & Associates
Building owners and operators have the unenviable job of figuring out how to respond to the growing demand for better indoor air quality (IAQ), which has been accelerated by the COVID-19 pandemic, while at the same time responding to expanding mandates to electrify and decarbonize buildings to address the climate crisis.
Heating and cooling large volumes of outside air to maintain comfort while diluting indoor-generated contaminants like airborne pathogens and volatile organic compounds (VOCs) can be very energy intensive in hot and cold climates. Conditioning all of this outside air also makes it harder to implement net zero energy solutions due to larger heating and cooling loads.
However, do the health and safety benefits of many common IAQ strategies justify the cost-, energy-, and carbon-penalties associated with increased outdoor air rates, increased filtration levels, and increased HVAC system run times? And are there alternative strategies that reduce the tension between IAQ and sustainability, particularly those making use of often-more energy efficient air cleaning and disinfection technologies?
In recent years, emerging commissioning approaches have enhanced the ability of engineering professionals to address the above challenges and questions, and sharpen field measurement and verification of HVAC system performance leveraging science, technology, and data, including aerosol tracing technology, real-time IAQ sensors and monitors, and IoT-enabled building management systems.
This session will provide: 1) a conceptual framework for commissioning HVAC systems for sustainable indoor air quality; 2) practical strategies for integrating emerging approaches and technologies with traditional commissioning services; and 3) applied case studies to illustrate the conceptual framework and integrated commissioning approach in action and highlight the safety, financial, and energy efficiency return on investment for real world clients.

Commissioning – An Owner’s Perspective
John Schaub, PE, Rock Island Arsenal
Proposals for commissioning work can often vary widely in terms of the level of effort. Unfortunately, the low bid typically provides the minimal service and in many cases, neither the project specifications nor the commissioning guidelines provide adequate guidance on whether a given level of performance meets with the owner’s expectations.
The Rock Island Arsenal has been actively using the commissioning process since 2014. Projects have included residential HVAC systems (3-4 Tons) to commercial HVAC systems (50-300 Tons).
This presentation will review the evolution of the commissioning process on the Rock Island Arsenal by looking at various projects over the past eight years. What difficulties or problems were encountered during the commissioning process? What happened after the commissioning process? How have these problems affected the procurement process at the Rock Island Arsenal. Finally, what needs to be done to improve and refine the commissioning process.

Electric Rate Structures – Importance of Analysis
Robert Knoedler, PE, CxA, EMP, Hanson Professional Services
Mat Coalson, Hanson Professional Services
An important part of an EMP’s services is examining their client’s energy usage (demand and consumption), establishing an energy balance and baseline. Along with an audit, this analysis affords insight to potential savings through changes in operations, as well as the estimated payback for implementation of various conservation measures.
However, equally important is an analysis of the client’s electrical rate structure. Electrical utility providers have a broad range of rates depending upon customer type (residential, commercial, industrial) and service size. With an increase in customers adding on-site generation, advances in energy storage and smart meter technology, and an increase in overall demand for electricity, utilities have become creative in their rate structures, often offering incentives to customers seeking to control their demand and costs.
This session will examine some of the rate structures commonly used by various utility companies, including net metering for customers with on-site generation and various incentives with the use of sub-metering. We will discuss analysis of these rates with respect to energy management, as well as the use of ‘blended’ electrical rates (often used in energy savings calculations) and show where these are valid and where more detailed calculations should be employed. We will briefly share information on the U.S. Utility Rate Database and discuss forecasting of future energy costs utilizing the government’s Energy Escalation Rate Calculator (EERC).5
- Examining the various types of electrical rate structures currently utilized by utility companies.
- Importance of analysis by energy managers; comparing alternate rate structures and the appropriate use of ‘blended’ electrical rates.
- Discussion of energy / cost saving strategies, including energy audits, retro-commissioning and demand response programs.
- Examination of various publicly available resources, including the U.S. Utility Rate Database and the government’s Energy Escalation Rate Calculator

ESG:Environmental, Social and Corporate Governance for Independent Third-Party Cx Providers
Jim Magee, CxA, EMP, Facility Commissioning Group
ESG is a risk management framework intended to build trust in markets through identification and management of sustainability-related effects and implications affecting the value of an enterprise. ESG concepts originate from a UN and international financial institutions collaborative report in 2004 titled “Who Cares Wins.” Since 2020, increasingly ESG data is overlayed with Sustainable Development Goals (SDG) developed by the United nations since the 1980’s.
In less than 20 years ESG has gone from a UN corporate responsibility initiative to a $30 trillion global network.
At the 2022 SERBCA/7×24 Technical Summit in Charlotte, the CEO of a major technology infrastructure developer and leaser to hyperscale businesses clearly stated, “ESG is required to raise capital for data centers. Engage locally and contribute to community.”
Organizations engaged in various types of infrastructure development and construction in numerous national and international economic sectors face ESG imperatives in acquisition and implementation of their services. This presentation seeks to provide basic understanding of ESG principals and insights into ramifications of changing procurement parameters on independent third-party commissioning provider (CxP) and energy management service operations.
Opportunities exist for CxPs and EMPs in emerging fields such as carbon accounting, where technical integrity and high ethical standards must be applied. We will discuss current carbon accounting schemes, where Scope 1 inputs are controllable by an enterprise, and Scope 3 inputs by vendors, suppliers and extractors are typically not included on balance sheets.
Topics include the circular economy connected to the built environment, life cycle accounting (another opportunity for CxAs & EMPs), greenwashing, UN global compacts, regulator involvement and DEI (diversity, equity and inclusion).
LEED has become a status quo metric. CxAs and EMPs will be engaging with ESG delivery models and organizational management parameters under developing construction and operational performance metrics. ACG member firms have begun including ESG in social media content and some have publicly accessible ESG reports to promote accountability with enterprise and client relationships.
Conceived as an introductory presentation on ESG, we will invite dialogue and questions to compliment the interests of the Cx Energy audience.

What do these terms really mean and why are they important to Building Commissioning and Energy Management professionals? This panel discussion between leading industry experts will attempt to shed more light on the future of the building performance industry and the role of commissioning providers and energy management professionals.
Using CO2 Sensors For Indoor Air Quality And Energy Savings
Darryl DeAngelis, LEED AP, EBTRON
Carbon Dioxide (CO2) is a bioeffluent produced by building occupants. It has therefore been used as an Indoor Air Quality (IAQ) metric. CO2 also exists in the outdoor ambient, is impacted by local environments, and is generally increasing. ASHRAE Standard 62.1-1989 introduced a mass balance equation that demonstrated a relationship between CO2, occupants, and ventilation rates. Thereafter control methods were developed and used to control ventilation by CO2 measurement. However, a change to the ventilation rate procedure in 62.1-2004, changed direct relationship between CO2 control and maintaining minimum ventilation. In the meantime, CO2 became the leading control method for demand control ventilation (DCV) and means to save ventilation energy, and studies showed that high levels of CO2 impacted human cognition and performance.
In 2018 the 62.1 committee started the process to update the standard so that minimum ventilation rates were correctly maintained when CO2 DCV was incorporated. Often commissioning and sequences of CO2 DCV systems are incorrect. This results in potentially wasted energy and more often, underventilation. During the COVID-19 pandemic stand alone and networked CO2 sensors were widely used to indicate weather a space was well ventilated. In 2021 ASHRAE Standard 90.1 came out with a new provisions on when DCV required. In 2022 ASHRAE published a Position Document on Indoor CO2.

A Deep Dive Into IAQ Data Using Data Analytics and Machine Learning
Julien Stamatakis, Attune
The concerns about, and the importance of, Indoor Air Quality (IAQ) has increased substantially. COVID-19 has sensitized the general public about what may be in the air that they are breathing. Building owners and operators are rightfully responding to these concerns in leveraging technology such as the Internet of Things (IoT) to bring assurance to building occupants.
As it is well known that expiratory human activities generate sub-micron airborne droplets, which can also carry viruses (e.g., COVID-19), enhanced air filtration strategies have been introduced using pre-filters or filters with different MERV ratings for different particle sizes. The efficacy of those advanced air filtration systems can only be determined using particulate matter (PM) sensors having sufficient quality and accuracy. This session will include an in-depth discussion of the different design choices of modern PM sensors to enable understanding of the impact on the quality of the PM data.
Additionally, an analysis of current outside-air intake strategies is provided in leveraging CO2 data from outside air, supply air, and return air monitoring points to calculate the percentage of outside air particles coming in vs the percentage of recirculated particles. HVAC system design can be further evaluated using practical application of Machine Learning (ML) to detect different system anomalies. For example, ML can be applied to (1) ensure outside air intake is adequate based on occupancy, and (2) detect anomalies in filtration efficacy that would indicate filter issue events that would generate more particles than the HVAC system can handle.
These case studies and others will highlight the utility of capturing real-time IAQ data from the physical environment. Illuminating the hidden reality of real-time airborne conditions will provide key decision makers with the data needed to not only numerically assess levels of airborne pollutants, but also leverage such real-time data in managing key HVAC system infrastructures within buildings.
1. Understand modern particulate matter sensors and the impact on the quality of the data.
2. Understand the significance of CO2 data from outside air, supply air, and return air monitoring points.
3. How machine learning can be applied to outside air intake and used to detect anomalies in filtration efficacy
4. Understand the use of capturing real-time IAQ data and how to leverage it for managing key HVAC system infrastructures in buildings.
ACG Building Systems Commissioning Guideline Spotlight: Electrical Distribution Equipment Terminology
Jesse Felter, SSRCx
Defining terminology that accommodates a wide range of Clients goals, while providing guidance for the commissioning provider (CxP) is often an reoccurring challenge, a challenge that the new ACG Guideline addresses. Where the construction industry appears vague or lacking in guidance for defining terminology, this presentation intends to provide several means of clarifying one such term, electrical power distribution, or electrical distribution equipment.
Learning Objective 1:
When best to establish common definitions for electrical distribution equipment in scope.
Learning Objective 2:
Who gets the final say in how scope and equipment are defined.
Learning Objective 3:
Using commonly accepted industry standards to help identify electrical distribution equipment.
Learning Objective 4:
Using other means and practices to help identify electrical distribution equipment.
Enclosure Commissioning: Maximizing Value

Jo Madrid, Wiss, Janney, Elstner Associates, Inc.
Building Enclosure Commissioning (BECx) and performance testing is required and implemented on more projects than ever before. An effective BECx program can be used to verify that the owner’s project requirements (OPR) have been achieved. This presentation reviews advanced BECx strategies, performance testing, LEED requirements, and critical, but often overlooked, strategies to maximizing the value of BECx.
Fundamentals of Commissioning for Facility Engineers and Building Owners
Loren Morris, PE, CxA, EMP, TMCx Solutions, LLC
Al LaPera, CxA, EMP, LEED AP, Kimley-Horn
This presentation will illustrate, how and why commissioning is an essential component for a building. Commissioning fundamentals from initial new building Cx to retro Cx to continuous or monitor based Cx provides both the building owner and facility a properly operating building cradle to grave.
- Understanding fundamentally the differences and important nuances between the various commissioning types.
- Discuss why on an existing building an initial energy audit should be a part of a successful retro commissioning project!
- How to identify typical “low hanging fruit” measures in each facility using existing tools and resources.
- Describe lessons learned from the process that would make project better.
