Applications of DDC in Building Management Direct Digital Control (DDC) systems are a key component of smart building infrastructure in modern facilities, enabling interconnectivity, remote management, and system integration. 1. Interconnectivity DDC controllers can operate as standalone devices when controlling an HVAC application, such as an air handling unit or a fan coil. However, in most cases, they are interconnected into a network known as a?Building Automation System (BAS). Through the BAS network, DDC controllers can exchange data with each other, such as occupancy schedules, load demand, alarms, and more, improving overall system operation and efficiency. 2. Remote Management Network connectivity among DDC controllers also enables remote management through a front-end portal, commonly referred to as a?Building Management System (BMS). Through the BMS, building operators can visualize HVAC equipment in a user-friendly interface, enabling equipment monitoring, setpoint adjustments, scheduling, fault detection, energy management, and visualization of historical trends. 3. System Integration Although DDC controllers are commonly used for HVAC applications, their potential for controlling and supervising other building systems is growing very quickly. Due to the interconnected nature of DDC devices, many building operators choose to integrate various other systems into the BAS network, such as domestic water systems, emergency generators, smoke evacuation systems, transfer power switches, lighting systems, and more. This integration allows operators to access all systems from a single location, improving visibility and oversight of building assets. Understanding the capabilities of new technologies is essential for facility managers and operators to manage resources and assets effectively. Embracing these innovations ensures staying competitive in a rapidly evolving market. Want to learn more about DDC systems and how your facilities can benefit from this technology?

Before Energy Management: Getting the Time Right ! How do we ensure that all HVAC systems operate according to their programmed schedules? ? We need time synchronization across all HVAC controllers. Time Synchronization: Each HVAC controller has an internal time clock that governs the scheduling logic programmed into the system. When the time clocks of these devices are not synchronized across the system, it can result in space comfort disruptions, unnecessary service calls, and even equipment damage. Effective HVAC energy management isn't possible without proper time synchronization between HVAC controllers. In fact, the most efficient energy management practices, such as occupancy-based night setbacks or night shutdown sequences, are entirely dependent on synchronized time clocks. How does time synchronization occur in HVAC controls? In large facilities and commercial buildings, HVAC systems are usually networked through a Building Automation System (BAS). Time synchronization happens via broadcasting protocols within this network. Pro Tip: Typically, there is a master time broadcasting device that pulls the time from a reliable source (usually the internet) and shares it with the rest of the devices in the network. Something as simple as time synchronization can affect space comfort and building operations for years. In many cases, when synchronization issues persist, building operators resort to leaving HVAC units running 24/7, leading to high energy bills and reduced equipment lifespan. Time synchronization is one of those details that often gets overlooked, but its critical importance can't be understated. With time synchronization in place, you're ready to dive into the next step, Effective Energy Management.

Is your HVAC system affected by static pressure performance issues? Here are the most common factors to consider: ? Undersized Air Returns: Undersized returns decrease the system's total static pressure, forcing the blower fan to work harder to pull air. In extreme cases, a fully closed return can cause the fan to spin without moving any air. ? Dirty Evaporator Coils: When cooling or heating coils are dirty, static pressure typically drops, making it harder for the unit to move air efficiently. ? Clogged or Overly Restrictive Air Filters: Clogged filters, or those with high filtration ratings, reduce static pressure, limiting the fan's ability to move air through the system. ? Incorrectly Sized HVAC Equipment: Undersized equipment lowers both static pressure and total airflow, leading to discomfort. Oversized equipment can increase static pressure, causing excessive noise, humidity issues, temperature imbalances, compressor short cycling, and potential system damage. ? Leaky Ductwork: Air leaks in the ductwork cause static pressure to drop, reducing energy efficiency and leading to condensation problems and higher energy bills. ? Improper Ductwork Design: Poor duct design such as incorrect sizing, sharp bends, improper vent placement, and inappropriate filter ratings can negatively affect static pressure when not calculated or installed correctly. ? Lack of Testing, Adjusting, and Balancing (TAB): The TAB agent ensures the HVAC system is installed, sealed, adjusted, and calibrated according to the design, including maintaining proper static pressure levels. Without proper TAB, system performance can be severely compromised, resulting in failures and inefficiencies. ? Lack of Control Commissioning: The commissioning agent (CxA) ensures the HVAC control system operates as intended. Non-commissioned control systems are a leading cause of energy waste in commercial buildings. Understanding static pressure performance in HVAC systems is critical to ensuring comfort and maintaining energy efficiency.

This additional capability of an EMS over a typical BMS unlocks multiple benefits, such as: ? Building Power Consumption Pattern Visualization: Real-time power consumption data for a building. This valuable and actionable information enables operators to adjust equipment operating schedules and setpoints, maximizing energy savings. ? System Power Distribution Visualization by End Use: Breakdown of different systems' power consumption and demand. This insight helps building operators identify the primary drivers of energy consumption and focus optimization efforts where they are most needed (e.g., HVAC, lighting, water heating). ? Power Pattern Anomaly Detection: Smart algorithms notify operators of performance changes in specific equipment or systems, helping prevent potential equipment failures, business interruptions, and costly energy bills. ? Building Power Consumption Optimization: Control strategies designed to maximize energy efficiency and power savings. HVAC and lighting systems are often the most targeted for optimization. ? Improved Bottom Line: Energy savings of 10% to 30% can be achieved through efficiency and optimization strategies, representing a significant capital boost for businesses looking to improve profitability and growth. Many facilities never develop a true EMS infrastructure. They typically reach a BMS level and stay there, missing out on the benefits an EMS can offer.

Fan Laws: Energy Efficiency & System Performance The fan laws describe the effects of changing a fan's RPM or speed on airflow, static pressure, and brake horsepower. ? Fan Law 1: Airflow (CFM) is directly proportional to RPM. For example, a 10% decrease in RPM results in a 10% reduction in airflow. ? Fan Law 2: Static Pressure (SP) changes with the square of RPM. A 10% decrease in RPM leads to a 19% reduction in static pressure. ? Fan Law 3: Brake Horsepower (BHP) changes with the cube of RPM. This means a 10% decrease in RPM results in a 27% reduction in horsepower. The fan laws provide valuable insights into fan performance under various operating conditions. They are typically represented as curves by fan manufacturers, helping engineers and system designers select mechanical equipment for different applications.
