Autodesk's Green Building Studio (GBS) is free software that helps you create models for your building and enables you to assess the impact of any specific design decisions on your energy consumption. You can also use the software to calculate environmental benefits based on different options for renewable energy, green roofs, landscaping, and water conservation.

Autodesk Green Building Studio is a flexible cloud-based service that allows you to run building performance simulations to optimize energy efficiency and work toward carbon neutrality earlier in the design process. Green Building Studio will help extend your ability to design high-performance buildings at a fraction of the time and cost of conventional methods.
