Cloud-based Energy Simulation Using EnergyPlus

This is a recording from a webinar that was hosted on February 10, 2015 to introduce the Project EnergyPlus Cloud available in Autodesk Labs. During the session Principal Engineer and Product Owner Krishnan Gowri demonstrates how to utilize EnergyPlus Cloud in addition to facilitating an open forum discussion for feedback.
Tortuga - a Global Warming Potential Evaluator for Grasshopper

Tortuga – a Global Warming Potential Evaluator for Grasshopper

Tortuga evaluates the Global Warming Potential (GWP) of your model. It provides a material editor which applies materials from the Ökobau.dat database to Grasshopper geometries. The database contains a huge variety of construction materials and processes including lifecycle and GWP data. Tortuga will display calculated GWP values and colorize the geometry accordingly. It provides a...
