Elevating the Passenger Experience: T3 North 2 Concourse Project Update
Photo Courtesy: Phoenix Sky Harbor International Airport Construction continues to move forward on the Terminal 3 North 2 Concourse (T3N2) project at Phoenix Sky Harbor International Airport, a major expansion effort designed to support the airport’s long-term growth while enhancing the passenger experience at one of the nation’s busiest aviation hubs. The project is currently […]
Designing for Decades: BIM‑Driven Collaboration That Improves Access in Complex Healthcare Facilities
By: John Reis, Principal Complex healthcare facilities demand more than successful construction, they require systems that can be safely accessed, inspected, and maintained for decades. On a recently completed 1.8‑million‑square‑foot university medical center, EEI Building Performance supported early, multidisciplinary BIM collaboration to help ensure long‑term access and maintainability across critical life‑safety and environmental systems. The Challenge During […]
R‑32 and VRF Systems: What Building Owners Need to Know
Variable Refrigerant Flow (VRF) systems are a popular HVAC system, providing efficient heating and cooling with great reliability. However, these systems are going through a major technology transition due to the phase-out of the refrigerant they use, R-410A. As of January 2026, it is illegal to manufacture or import new R-410A VRF equipment in the […]
NCEO 2026 Conference Wrap-Up: Insights, Energy, and Employee Ownership in Action
The NCEO 2026 Annual Conference in Milwaukee, Wisconsin brought together a powerful community of employee ownership advocates, business leaders, and industry experts and it did not disappoint. From the moment the conference kicked off, there was a clear theme: employee ownership is not just growing, it’s evolving. A Standout Keynote: Adam Grant One of the […]
How a structured RCx process uncovers hidden issues, improves comfort, and delivers measurable energy savings.
What Is Retro-Commissioning (RCx)? Retro-commissioning (RCx) is the systematic process of evaluating and optimizing the performance of an existing building’s systems—HVAC, controls, air distribution, hydronic systems, and supporting equipment. Unlike major capital upgrades, RCx focuses on improving what you already have. Over years of operation, buildings drift: schedules change, sensors lose calibration, economizers get overridden, […]
How to Develop a Monitoring-Based Commissioning (MBCx) Plan — and Why It Matters Now
Monitoring-based commissioning (MBCx) is no longer an optional strategy for high-performance buildings — it’s the foundation for maintaining efficiency, comfort, and reliability throughout a facility’s life. Unlike traditional commissioning, which confirms performance at turnover and then ends, MBCx is a continuous process that monitors actual system operation over time. It uses analytics, sensors, and ongoing […]
7-Step New Construction Building Commissioning Process for High-Performance Buildings.
Commissioning is a structured, quality-focused process that verifies building systems are designed, installed, tested, and operating in accordance with the Owner’s Project Requirements (OPR). When delivered successfully, commissioning reduces operational risk, improves energy performance, enhances occupant comfort, and supports long-term asset value. For owners, developers, and construction teams, commissioning is not an end of the […]
Existing Building Commissioning (EBCx): Retro- and Re-Commissioning Explained
Commissioning is often associated with new construction, yet many of the greatest performance improvement opportunities exist in occupied, existing buildings. As facilities age, equipment performance degrades, control strategies are overridden, and system operation gradually drifts from original intent. Existing Building Commissioning (EBCx) provides a structured, engineering-led approach to understanding how building systems operate today, and […]
Water Reimagined: How LEED v5 Transforms Water Efficiency and Performance
A Three-Part Conversation with Rock Ridolfi, Former Chair, USGBC Water Efficiency Technical Advisory Group (WE TAG)
ENERGY STAR Portfolio Manager in 2025: Still the Smartest Benchmarking Move: A trusted tool for performance and compliance
For more than two decades, the ENERGY STAR Portfolio Manager has been the go-to platform for tracking and improving building energy performance. According to the EPA’s Portfolio Manager Data Explorer, it now contains performance data from over 150,000 U.S. commercial, multifamily, and institutional properties – from office towers to university campuses. Owners and operators use […]
