The OpenStudio version 0.8.0 release focuses on integration with the NREL Building Component Library (BCL). The BCL is an online repository of building data used to create building energy models. The BCL can be accessed through a Web API to search for and download data for use in energy modeling. In this release, the OpenStudio application has been extended to use this Web API to enable searching, downloading, and using construction components from the BCL from within the OpenStudio application. Once components are downloaded from the online BCL to a user’s local library, they are available to use in the OpenStudio application. This capability can be accessed in the OpenStudio application by selecting the menu item “Window”-> “Online BCL”. A BCL API key is required to use this new functionality; instructions on how to obtain a BCL API key are available at https://openstudio.nrel.gov/using-building-component-library-bcl-key-openstudio.
