From Boiler/Tower to AWHP: Practical Design of Electrified WSHP Systems – John Sustar sponsored by Trane Technologies

Wednesday July 22, 9:00 AM

Electrified water-source heat pump systems (WSHP) offer a practical pathway to decarbonize buildings, reduce on-site water use, and simplify maintenance by replacing boilers and cooling towers with an air-to-water heat pump (AWHP). This approach builds on mature distributed water-source heat pump systems, which have long been used in multizone buildings.

This session examines the design implications of these electrified systems that use an AWHP for both heat addition and heat rejection. It will compare the efficiency of electrified and traditional WSHP systems, including the effects of compressor lift, heating and cooling performance, and potential cooling-efficiency tradeoffs. Design topics will include AWHP sizing, defrost and ambient temperature limits, auxiliary heat, pumping and flow management, and the roles of buffer tanks, glycol, dry coolers, economizers, and backup boilers. The session will also discuss enhancements such as thermal storage, load shifting, exhaust heat recovery, hybrid systems, and domestic hot water integration.

John Sustar started in the HVAC industry in 2009, specializing in energy modeling, electrical, mechanical, and hydronic systems. As an HVAC Systems Product Manager at Trane, he leads the development and execution of commercial systems strategies, working closely with engineering and marketing teams. He holds a master’s in building systems engineering from the University of Colorado–Boulder and a bachelor’s in electrical engineering from the University of St. Thomas.

In his current role as Systems Portfolio Product Manager, John develops and implements commercialization strategies across Trane’s commercial businesses, working with product managers, engineering teams, applications experts, sales teams, and marketing partners. He leads market activation plans for new system introductions and supports sales enablement through training, customer engagement, and content development. Previously, he served as the Commercialization Execution Leader for Chillers and held multiple engineering roles supporting water‑cooled chillers, energy modeling software, and customer technical support.

John lives in La Crosse, WI, with his wife and three kids. He enjoys spending time outside with his family, engaging in activities such as skiing, mountain biking, and trail running.

From OPR to Operations: Using Project Requirements to Make Buildings Perform – Candice Rogers and David Burks sponsored by the Bluegrass ASHRAE Chapter

Wednesday July 22, 10:00 AM

High-performing buildings do not happen by accident. They begin with clearly defined Owner’s Project Requirements and continue through disciplined design verification, field testing, and operational handoff. This session will explore how an effective OPR establishes both qualitative goals and quantitative performance criteria that guide project decisions from the earliest planning stages through occupancy.

Candice Rogers and David Burks will discuss practical methods for defining OPR criteria that is useful to design and construction teams. The session will then show how those requirements are carried forward through the design and construction process. Attendees will see how the OPR becomes a tool for accountability: first confirming that the design meets the Owner’s goals, then verifying in the field that systems are operating as expected.

The session will conclude by connecting the OPR to Current Facility Requirements, showing how project-phase expectations can transition into long-term operational guidance for facility teams. Participants will leave with a stronger understanding of how the OPR supports better decisions, clearer verification, and buildings that better serve their owners and occupants.

The Case for Modular HVAC: Enhancing Project Performance Through Offsite Manufacturing – Rodney Sproul sponsored by Daikin

Friday July 24, 8:00 AM

Packaged modular HVAC equipment is transforming mechanical system delivery in construction by shifting fabrication, assembly, and testing from the jobsite to controlled factory environments. This approach can reduce installation errors, enhance overall system reliability with consistent/standardized manufacturing and quality control. In addition, modular HVAC systems can shorten project build schedules by shortening unit installation time through offsite fabrication not impacted due to jobsite weather or labor shortages along with field constraints having to work across multiple trades. Some of those ‘hidden’ costs can be almost eliminated with modular systems as this shifts onsite costs to factory costs reducing onsite labor, minimizing material waste, improving productivity, and decreasing rework and schedule disruptions.

A graduate of the University of Kentucky with a degree in Chemical Engineering, Rodney Sproul lives in Lexington, Kentucky, with his wife and four children. As a Sales Engineer with Thermal Equipment Sales, he focuses on air side HVAC products and works closely with customers, contractors, and design engineers to deliver HVAC solutions for projects ranging from small retail spaces to schools, healthcare facilities, and other commercial buildings. He is passionate about improving building performance and efficiency through practical solutions, including the application of modular HVAC systems.
