Integrated Environmental Solutions (IES), creators of the IESVE plug-in for Google SketchUp enables the direct translation of models for performance analysis within any of following tools: VE-Ware, VE-Toolkits VE-Gaia and VE-Pro. "This integration allows SketchUp modelers to more easily take sustainable building decisions into account early in the design phase. It provides options for design iterations in the areas of energy, carbon, water, climate impact, solar and daylight analysis early on. This partnership, which continues to grow and strengthen, will benefit architects and engineers by providing a low-cost, high quality solution for sustainable building," explains Google.
Here's a sample:
