Zero+ Campus Mission

How can we create net-positive buildings, landscapes, and communities?Can we use the campus buildings and landscapes to:• Generate energy, preserve and restore water, eliminate emissions, reduce climate

impact, and regenerate the environment?• Explore, test, and pilot a new generation of integrated design strategies and tools across

disciplines, ecological issues, and scales?• Integrate the education, research, and campus planning missions to actively engage

students, faculty, and staff to explore these integrated design questions?

• What is the difference between minimizing harm and maximizing good?

• What are the performance implications of design decisions?• How can we optimize performance in design?Design Challenge• Integrating zero+ resources and tools for decision-making in the early design phases


Zero+ Research and Decision Tools: Assess existing design tools and develop the “Zero+ Toolkit” to support early design and decision-making processes. Pilot-test tools in the classroom and for integration into the early design phases for capital planning. Z+ Toolkit and Website

Stakeholder Process:Evaluate campus design and decision-making processes to more effectively integrate energy and water strategies. Select key capital projects for research and course investigation in early design phases. Pilot Projects and Tools

Zero+ Curriculum Develop courses

to investigate early design

strategies, metrics, and tools

that can be brought back into the early phases

of the capital planning and

predesign.5 Courses

Demonstration Projects: Design and construct demonstration

projects to engage students, promote sustainability, and test energy and water

strategies on campus.Bike Pasture

BRIDGING THE EARLY DESIGN TOOL GAP: Z+ Tool DevelopmentBeta Versions: 1) Z+ SketchUp Plug-in+IES-VE and 2) Z+ Calculator Prototype: 3) Z+ Campus Modeler• Limits of Existing Tools: scale and strategy limitations, accuracy, time, lack of design integration• Z+ Tool Response: 3-D interface with robust analysis tool (IES-VE) which can be combined with

zero+ calculator to compare baseline and strategies using campus building and performance data• User Options: Either a 3-D or menu-based interface (for students/architects and planners)

Zero+ Tool Evaluation and Development: Energy/Water Nexus

Beta Version Developed:

1. Zero+ Shoebox Model Maker Z+ SketchUp Plugin + IES-VE Pro

Concept:• Remain within design tool while

interfacing with an accurate analytical tool

• Quickly compare baseline building with alternative design strategies

• 3-D interface to evaluate ecological and economic benefits


2. Zero+ CalculatorExcel Spreadsheet Analysis Tool

Concept: • Use performance data from

UMN buildings to compare baseline with design strategies

Z+ Shoebox Plugin Demo


Zero+ Shoebox Plugin Demo

To create a shoebox model in Sketchup the Zero+ Shoebox plugin is selected.


Basic Building parameters are entered including floor area, height, aspect ratio, window type and window-to-floor area ratio, skylight type and skylight-to-floor-area ratio, etc.


The surrounding buildings are specified.


The shoebox model is now created in only seconds, complete with all windows, interior partitions and as defined in the dialog box queries.


Using the IES VE Plugin we can set location, building occupancy type and make construction assignments.


After identifying rooms the model appears in X-ray view. Now the model is ready for export to IES VE for analysis.


Rooms are represented in blue, active zone is red and all objects assigned as shade are yellow.


After clicking on the IES tool in Sketchup, a model is created in IES with all the walls, windows, external buildings, shading and settings made in the Sketchup model. Building Occupancy may be adjusted as well.


Shoebox Model can now be viewed for accuracy using the IES VE Model Viewer.


First the shoebox model is evaluated for overall performance including energy use and carbon emissions using the free tool, IES VEWare


Shoebox Model can now be evaluated for climate, energy, daylighting, renewable energy potential, and various LEED Credits using IES VE Toolkits.


Heating and Cooling Loads analysis of Shoebox Model using IES VE Toolkits.


Solar shading analysis of Shoebox Model using IES VE Toolkits.


Detailed model can be modified in IES VE for further analysis.
