By Cx Associates and Our Peers
August 2018: Managing Principal Jennifer Chiodo presented "Driverless Buildings: Harnessing Software for Uber Deep Savings" at the ACEEE Summer Study on Energy Efficiency in Buildings in Pacific Grove, CA. As her abstract describes, "As baseline equipment efficiencies continue to progress, C&I energy savings are increasingly dependent on improved system control through building automation. Unfortunately, most building automation systems (BAS) have limited persistence, because they are poorly programmed and, therefore, habitually overridden.
"There is a path to driverless buildings that will run without need for constant adjustments. Industry experts working on the leading edge of building controls programming for delivery of comfort, fresh air and lumens will share direct experience with moving the market toward optimally efficient system operation."
April 2018: Cx Associates has developed an outline of an Owner's Project Requirements (OPR) document. The creation and distribution of this document was inspired by Jennifer Chiodo and Dave Keelty's presentation on inclusive OPR processes at the 2018 Better Building by Design conference (see description and link to presentation below). It serves as a guideline for new construction project team members who are tasked with developing project objectives and delineating owner's expectations.

February 2016: Better Than Before – HVAC System Improvements via Engineered Retrofits. The inevitable replacement of HVAC equipment opens up opportunities for engineered retrofits that improve system-level HVAC performance. The presenters show how to take a systems-level approach to equipment replacement scenarios to reduce both the first cost and the operating cost of HVAC equipment. The presenters share real-world examples of engineered retrofits of HVAC systems - The example projects illustrate the application of new, higher efficiency HVAC technologies, and how these technologies can enable engineered retrofits of HVAC systems with improved life-cycle performance.
June 2014: Retro-commissioning Best Practice Study, MA Energy Efficiency Advisory Council. Cx Associates Managing Principal Jennifer Chiodo led the study resulting in this paper which describes the results from a collaborative effort to identify retro-commissioning (RCx) program features that qualify as best practices. Adoption of these practices could help the Massachusetts Program Administrators (PAs) achieve higher levels of participation and savings through retro-commissioning.
February 2015: Health Care Best Practices Study, MA Energy Efficiency Advisory Council
This paper describes the results from a study conducted by the Massachusetts EEAC Technical Consultants with input from the Massachusetts Program Administrators (PAs). The study purpose was to investigate key factors affecting the health care market and to identify program elements that effectively advance energy efficiency in the health care sector for consideration as potential best practices.

December 2013: Vermont Public Service Department Energy Savings Account Program Process Evaluation
This report presents the findings of the process evaluation of the State of Vermont's Energy Savings Account (ESA) program. This process evaluation report fulfills a statutory requirement for the Vermont Public Service Board (PSB) to evaluate "participation and experience with the ESA option," and fulfills one evaluation component included in the Department of Public Service's (DPS) Board approved EEU evaluation plan. The scope of this evaluation includes an investigation of the ESA program statutory requirements to date, an operational review of the ESA program administration by Efficiency Vermont (EVT), an assessment of the experiences of ESA program participants, and elicitation of insights from potential program participants. 1085_VT_DPS_ESA_Process_Eval.pdf
August 2013: Jennifer Chiodo was the lead author of, "Compared to What? An Alternative Strategy for Estimating Commercial and Industrial New Construction Baselines," a paper she presented with the team at IEPEC 2013 in Chicago.
June 2013: Matt Napolitan and Brent Weigel's article, Condensing Boilers: Maximizing Benefits appears as the cover story of the June 2013 issue of Engineered Systems magazine.
March 2013: Tom Anderson gave an updated presentation of "Strategies for a Meaningful Design Review" at the Building Commissioning Association's Northeast Chapter summit in Keene, NH.
March 2013: Eveline Killian presented "Calibrated Modeling – How Well Does My Building Perform" at the New York State Green Building Conference in Syracuse, NY. You can view her entire presentation on Slideshare.
January 2013: Tom Anderson and Jennifer Chiodo's article, Building Performance Monitoring And Metrics: Putting Building Data To Work was published in Engineered Systems Magazine, a leading publication that "provides practical, energy-efficient solutions for mechanical engineering projects."
November 2012: Eveline Killian and Emily Cross presented an online webinar for Onset Computer Corp, "Calibrated Energy Modeling Using Measurement and Verification." Their 90-minute course course explained how data loggers are used to adjust energy model input values, and how to calibrate energy model outputs to utility bill data. By creating weather normalized models, calibrated modeling ensures the model is representative of real world conditions. Energy models calibrated in this way can be used to accurately inform efficiency program impact evaluations, quantify discrepancies with LEED M&V models, and inform future energy investment decisions.

January 2012: Verification of Efficiency Vermont's Energy Efficiency Portfolio for the ISO-NE Forward Capacity Market
The Department completed its independent verification of EVT's peak demand reduction. EVT's M&V plan as submitted to ISO-NE was the foundation for the sampling plan and verification activities conducted by the Department. The realization rates are based on EVT's activity in program year 2009. The M&V plan was followed and the results of the evaluation are consistent with the ISO standards, as specifically discussed in this document.FCMFialReport09v2.pdf
