Nonresidential Direct Digital Controls

2016 Title 24 CASE Topics

Measure Overview

The Direct Digital Control (DDC) measure would require DDC systems for certain building applications that are currently not required by Title 24. By expanding the scope of applications requiring DDC, energy management data would be more readily available allowing for more efficient systems operations and the implementation of effective energy efficiency strategies. The measure would also specify the minimum capability of such mandated DDC system to ensure the full benefit of DDC for the best energy management practices
