Johnson Hall is the new home for College of Engineering research laboratories, teaching space and faculty offices. Johnson Hall is located near Kelly Engineering. Key Features: Chilled water will be provided using excess capacity from the Kelley Engineering Building chillers. This will also set the foundation for additional district chilled water systems in the future. Domestic water heating will be provided by a heat pump water heater, which improves overall energy use by 4% from the baseline building. A physical wind model study provided data that will allow the settings for laboratory exhaust to vary with the wind conditions. This provides large savings in both the fan energy for the exhaust and a reduction in exhausted heating and cooling. Two black walnut trees located near the site that need to be removed will be milled for use in the building.
