## What is Data Clearing House? 

[Data Clearing House](https://dataclearinghouse.org/v2/dashboard/) (DCH) is a data integration, management, and application enablement platform. It is a single location for accessing a wide range of energy and building data. The DCH connects Internet of Things (IoT) systems from buildings and supports complex data analytics.
