What Are Direct Digital Controls and How Can Facilities Managers Utilize Them?

Direct digital controls (DDC) are automated systems that are used to monitor and control certain environmental factors in buildings. These controls are typically used in buildings to regulate the temperature, humidity, lighting, and airflow. DDC systems can be used in both commercial and residential settings and are becoming increasingly popular for facilities managers looking for more efficient and cost-effective ways to maintain their buildings.

What are the Benefits of Direct Digital Controls?

The primary benefit of DDC systems is that they can be used to create an environment that is comfortable for occupants and efficient for the building’s operations. DDC systems can be used to monitor the temperature and humidity of a building, allowing the facilities manager to make adjustments to the air conditioning or heating systems to maintain a comfortable temperature. In addition, DDC systems can be programmed to turn lights on and off automatically when they are no longer necessary, reducing energy costs.

How Do Direct Digital Controls Work?

DDC systems use sensors to monitor and control various environmental factors in a building. These sensors collect data and send it to a central control unit, which is then used to adjust various systems in the building. For example, a DDC system can be used to adjust the air conditioning or heating systems based on the current outdoor temperature. The system can also be used to adjust the lighting in a room based on the amount of natural light available.

How Can Facilities Managers Utilize Direct Digital Controls?

Facilities managers can use DDC systems to monitor and adjust the environment in their buildings to create a comfortable and efficient environment. By using DDC systems, facilities managers can reduce energy costs by automating the operation of lights and HVAC systems, as well as monitoring the temperature and humidity of the building. Additionally, DDC systems can be used to detect water leaks and other issues that could lead to costly damages.


Direct digital controls are becoming an increasingly popular tool for facilities managers, as they offer a more efficient and cost-effective way to monitor and control environmental factors in buildings. DDC systems can be used to reduce energy costs, ensure the comfort of building occupants, and detect potential issues before they become costly problems. As DDC systems become more advanced, they will continue to offer more benefits for facilities managers.
