Tour - 6:45 pm

Main Presentation Highlights:

The University Row development is a developer-driven, multi-building complex on the location of the old Marshall Erdmann offices. This sustainable development includes a new, LEED Platinum office building completed in 2014. This presentation and tour will outline the building’s unique design process as well as its many sustainable features. Specifically, the presentation will go into detail about the building’s ground source variable refrigerant flow (VRF) system, as well as design considerations for using both air and water source VRF systems in cold climates.

VRF systems use variable speed, split air source or water source heat pumps to provide space heating and cooling to a building's conditioned areas. Air source VRF systems are increasing their market share in moderate climates. However, they are not as widely implemented in cold climates, as they typically lose capacity and efficiency at low ambient temperatures – or moderately low wet bulb temperatures where defrost is required – and may be supplemented by an additional heat source. Alternately, low temperature performance may be mitigated by upgrading to a water or ground source system. Significant questions remain regarding how to design and operate both air and water source VRF systems in cold climates for optimal energy performance, while minimizing risks of under capacity. This presentation will outline the optimal control strategies for designing and operating both air and water source VRF systems in cold climates.


Scott Hackel, PE, LEED AP

 Seventhwave – Principal Energy Engineer

Scott consults with architects and engineers on energy efficient building designs and systems. He also conducts applied research on technologies and processes through both 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; at the national level being an integral part of the Geothermal Energy technical committee. He's also a member of the Wisconsin Green Building Alliance.


Scott Schuetter, PE, LEED AP

 Seventhwave – Senior Energy Engineer

Scott analyzes efficient building designs and researches various energy efficiency technologies. He has extensive experience with both energy and daylight modeling. Scott is a large-scale batch energy modeling specialist who focuses much attention on modeling campuses, communities, and regions. In addition, he studies climate change impacts on building energy consumption and demand. He is an active member of ASHRAE.


Carol Mori, PE, LEED AP, QcP

Project Engineer – General Heating and Air Conditioning

Carol has been in the HVAC design and design/build industry for close to thirty years. After a dozen years with Affiliated Engineers, Inc, she moved to GHAC where she partners with clients, general contractors, and architects to design and build energy efficient, cost effective and comfortable mechanical system. Carol has extensive experience with analyzing HVAC problems, addressing client HVAC related concerns, commissioning, estimating, and system developement and engineering.

Carol is an active member of ASHRAE at the local level having held a position on the Board of Governors for the past seven years in Chapter Officer positions and as several Committee Chairs. Carol is currently the General Chair for the 2016 CRC to be held in Madison this spring.
