From RCx to NCx - the Current State of RCx, & Beyond

Abstract

Since the 1990s, building commissioning (Cx) has grown from a concept to a spectrum of established services and business offerings with billions of dollars of revenue; in parallel, retro commissioning (RCx) thrived abruptly as a best-practice for existing building stocks and O&M, with monitoring-based Cx (MBCx) to follow and revolutionize effectiveness and efficiency. Examined thoroughly, RCx traces back to a variety of distinguished roots, blossoms in copious shapes and colors, and sets for sumptuous destinies. On the other hand, re-commissioning (Re-Cx) or existing building Cx (EBCx) are sometimes preferred terms, which puts RCx a terminology or technology at large. This presentation illustrates the presenter’s view, reflections and visions, aiming to convince the audience why he self-claimed as “Mr. RCx”, or “Mr. NCx” and “Mr. LC-MBCx”, preferably, into the future.

Song formerly served as an Associate Director at the Energy Systems Lab of Texas A&M University, where he directed an internationally leading group of researchers, engineers, technicians and graduate students implementing building energy efficiency projects with an annual R&D/consulting budget over $8 million. He was the lead Principal Investigator for a comprehensive energy management program on the Texas A&M university campus, for which cumulative savings exceeded $90 million over a period of 16 years. Teamed with Dr. W. Dan Turner, the two personally walked through and assessed more than 600 buildings and campuses globally during the past three decades, leading cutting-edge data-driven energy conservation and asset/resource management programs resulted in measured and documented avoided costs and energy savings over $300 million. They co-developed DOE/AEE’s MCBCP® certification course and AEE’s CBCP® International certification course. Song is also on World Bank’s roster of energy efficiency experts. In 2010, Song and Dr. Turner co-founded the Theory of Nodal Partners, which reflects their view of today’s world, IT, energy and utility’s supplies, transportation and consumption, smart grid of everything, interplay and readiness. Currently, as the CEO/Technical Advisor at Austin, TX-based Bee (Building energy efficiency, BeeUSA.com), Song consults and lectures worldwide in the scientific fields of monitoring & platform based life-cycle building commissioning, master planning, asset and resource management, ESPC, UESC and PACE independent 3rd party M&V and integrated quality assurance, energy efficiency, O&M, sustainability and resiliency, smart buildings/campus/grid, CHP, TES, district and micro-grid, big data analytics and fog intelligence.
