Scott Hackel consults with architects and engineers on energy-efficient building designs and systems. He also conducts applied research on technologies and processes through field monitoring and extensive energy modeling. He has specialized in the study of ground-source heat pumps, and lighting and HVAC controls. Scott is an active member of ASHRAE at both the local and national level, including as an integral member of the geothermal energy technical committee. He's also a member of USGBC Wisconsin. Scott holds bachelor’s and master’s degrees in mechanical engineering from the University of Wisconsin-Madison, as well as a graduate certificate in energy analysis and policy.

Jason LaFluer is dedicated to market transformation for high-performance buildings. He has vast experience with commercial and residential design, construction, and operations of high-performance buildings, including experience with net zero energy design. With GTI, Jason is a senior program manager in energy efficiency and building science, and is involved with project management functions on a number of federal contracts and local distribution companies in the utilities sector.

Jennifer Li conducts electrical engineering and lighting design analysis for commercial and industrial new construction and renovation projects, with a concentration on energy efficiency and sustainability. She holds a bachelor’s degree in electrical engineering from the University of Wisconsin-Madison.

Greg Marsicek uses energy modeling software (TRNSYS, eQuest, and others) and his FORTRAN programming knowledge to analyze buildings and energy systems to help buildings owners and design teams make informed design decisions. No building or project is the same, and thus there are no “cookie-cutter” solutions or modeling approaches. Greg is an active ASHRAE member and holds bachelor’s and master’s degrees in mechanical engineering from the University of Wisconsin-Madison.
