Direct Digital Control Technology is the control of a building’s conditions through a digital device, typically a computer. It is a system that is commonly aligned with Building Automation Systems. And, it is mainly used in commercial HVAC control and energy management system applications. In a commercial building, Building Automation Systems (BAS) and Direct Digital Control Technology (DDC) work together to provide programmable and precise control of the building’s functions.

The term BAS stands for Building Automation Systems. Such a system is installed in a high-performance building during construction. A BAS system allows the building to be more energy efficient. The system will also be used to monitor the structure and ensure all components are working properly. Building Automation Systems also provide data which can be used to show how high-performance buildings work. This helps to see financing offered to companies that want to construct such facilities.

The term HVAC stands for heating, ventilation and air conditioning, a system used to control the temperature in a space as well as humidity and quality of air. In a big building, the system needs to be able to function based on comfort need as well as meet the size of the space. The HVAC system must transfer heat and moisture into and out of the air to control the temperature level, as well as the level of air pollutants. This is done by removing the pollutants directly or by diluting them.

The heating, ventilation and air conditioning system is one part of your building that when it works, you take it for granted. In the same vein, if it’s defective, you will really feel every minute that you are inside the four-walled structure. Installing this system in a new building is complicated enough, but retrofitting HVAC for historic buildings is a whole other level altogether. We have compiled a list of guidelines to retrofit HVAC for historic buildings.

Twenty to thirty years ago it was common practice to install a CAV (constant air volume) system in commercial buildings for ventilation and air-conditioning. These types of HVAC systems require high airflow rates and higher amounts of energy for heating and cooling. Thus, increasing utility costs. Therefore, the theory is, […]
