Project Title Two (2) 175 Ton (350 Tons total) Chiller Geothermal Heat Pumps for recently commissioned LEED Platinum Building
Project Type / Topic 1 Recovery Act – Geothermal Technologies Program: Ground Source Heat Pumps
Project Type / Topic 2 Topic Area 1: Technology Demonstration Projects
Project Description Johnson Controls recently completed the construction of a new, LEED platinum certified, headquarters building in Glendale, WI (Milwaukee suburb). The project utilizies many energy saving and sustainable technologies including solar and geothermal. The geothermal system is comprised of 272 wells at a depth of 300 feet, a closed loop heat exchanger using 100 percent groundwater, and two (2) 175 ton geothermal chiller heat pumps which are expected to reduce winter heating costs by 29%, summer cooling costs by 23%, and summer heating costs by 57%. As the heat pumps have recently been commissioned, Phase III activities can begin immediately.

The marketing of this project will be viewed as a success when chiller geothermal heat pumps move from their current niche status to being widely deployed. Johnson Controls and the DOE can quickly make this a reality. Wide-deployment of this technology will create over 900 long-term jobs, provide over $14M in yearly energy savings, reduce our dependence on foreign energy, and reduce greenhouse gas emmissions.

State Wisconsin
Objectives Operate, collect data, and market the energy savings and capital costs of a recently commissioned chiller geothermal heat pump project to promote the wide-spread adoption of this mature technology. Innovative marketing programs will be developed and shared with the DOE, and the site will serve as a chiller geothermal heat pump showcase.

Funding Opportunity Announcement DE-FOA-0000116
DOE Funding Level (total award amount) $311,324.00
Awardee Cost Share $311,324.00
Total Project Cost $622,648.00

Principal Investigator(s) James F. Dagley, VP Marketing & Strategy, Johnson Controls, Inc.

Targets / Milestones - Operation: The operation of the entire heat pump system is fully automated. The details of its optimized sequence of operation in all weather and building load conditions will be documented and shared.

- Data Collection: The existing building automation system will be programmed to automatically collect all necessary data points to properly document energy consumption. - Marketing: Real-time energy savings will be calculated via the building automation system, and presented to the public via an interactive “kiosk” at the site. The kiosk will also be accessible to the pubic via the internet. A video will be created documenting the construction process, the capital costs of the project, and the energy savings of the chiller geothermal heat pumps. To maximize exposure, the video will be made available to the public via various websites available to Johnson Controls and the DOE. The mechanical room housing the heat pumps was constructed with large windows to enhance public tours and serve as a showcase. As daily public tours are anticipated, a full-time customer briefing representative will be hired to conduct tours and promote the technology.

Location of Project Glendale, WI

Impacts Project offers unparelleled customer awareness and marketing potential with state-of-the-art data monitoring and sharing abilities, including public tours, video, and Internet sharing. A showcase facility for region that will really increase visibility for this technology.
