Zero+ Shoebox Model Maker

 

The Zero+ Shoebox Model Maker is a Google SketchUp™ plug-in intended for early stages of project planning and design when basic building parameters and characteristics are known, yet design has not yet begun. The initial version of the plugin is intended to be used in conjunction with Integrated Environmental Solutions <Virtual Environment> (IES VE) software including the IES Plug-in for Sketchup. Later versions may be developed to work similarly with the Department of Energy's EnergyPlus and its Google SketchUp™ Plug-in and Openstudio (see Tools Matrix). The Zero+ Shoebox Model Maker allows the user to quickly create a"shoebox" model of the proposed building and to quickly model and evaluate a variety of strategies, glazing area ratios, and building configurations. The "shoebox" can accrately model floor area, geographical location, surface area, orientation and construction and building types. Comparative shoebox models are exported to any of the IES VE software tools for a variety of analyses and evaluations (e.g., energy use, carbon emissions, benchmark against the 2030 Challenge, daylighting analyses, and a variety of LEED® rating system credit assessments). The following screen images show the progression of steps one would follow to perform such evaluations using the "Zero+ Shoebox Model Maker" SketchUp™ plug-in.

 

Step 1 Step 2
Step 1: In Google SketchUp™ the user selects the Shoebox Model Maker from the plug-in Menu. Step 2: A dialog box opens with default building size and configuration data which is then edited by the user to match the project, e.g. total floor area, number of stories, plan aspect ratio, window to floor area ratio, percentage of windows oriented south, window type, window shading, toplighting configurations, etc.

 

 

Step 3 Step 4
Step 3: A dialog box is used to enter data to create surrounding buildings and the shading impacts on the project. Step 4: The shoebox model is created with the surrounding buildings (if any).

 

 

Step 5 Step 6
Step 5: The IES plug-in is used to identify the location, climate data, envelope specifications, building type, and HVAC systems. Defaults can be accepted for any of these variables (with the exception of location) or used to create a variety of options for comparison. Step 6: The surrounding buildings and window shading are set as shading elements.

 

 

Step 7 Step 8
Step 7: Using the IES plug-in, the rooms are defined to prepare the model for analysis using the IES VE tool of choice. Step 8: Once the VE option is selected in Sketchup, IES VE is launched and the model is ready for simulation.

 

 

Step 9 Step 10
Step 9: The screen shows the progress of the simulation which may take several minutes depending on your processor speed. Step 10: In IES VE Pro the model can be viewed to ensure that the model was created and imported as intended.

 

 

Step 11 Step 12
Step 11: Using the IES VE Ware energy carbon emissions tool, a report is generated providing baseic energy use, loads breakdown, and 2030 Challenge benchmark comparison to the shoebox model. Step 12: If the user is using IES VE Pro, they can now proceed to explore the full analytical capabilities of the software, including Radiance for high level daylighting evaluations.
