Case study: Advanced HVAC controls across a university campus

HVAC control insights:

• Advancements like direct digital control systems allow commercial buildings to have more control over temperature and air quality.  

• Implementing advanced HVAC control systems offers building owners a high return on investment compared to keeping older systems.  

One prime example of how advanced heating, ventilation and air conditioning (HVAC) systems can transform a facility is McKinstry’s work at Washington State University (WSU) North Puget Sound Campus. This project involved upgrading HVAC controls across multiple buildings, leading to a dramatic improvement in energy efficiency and occupant comfort.  

At WSU, the installation of advanced HVAC systems, including direct digital controls (DDCs), allowed the university to monitor and manage different zones more effectively. The new system provided better climate control in classrooms, offices and laboratories while reducing overall energy consumption. By focusing on predictive maintenance and real-time monitoring, the facility management team was able to detect potential issues early, reducing downtime and minimizing repair costs. This project illustrates the significant benefits that can be achieved through modern HVAC controls, especially in complex environments like university campuses.  

Why HVAC control upgrades make sense

For many businesses, the question is not whether advanced HVAC controls are beneficial, but whether the investment is worth it. The answer is a resounding yes. The typical return on investment (ROI) for upgrading to a DDC system ranges between 25% and 50%, depending on the age and efficiency of the existing HVAC equipment. Factors influencing ROI include energy savings, reduced maintenance costs and the longevity of new systems.  

Moreover, beyond the financial ROI, the impact on employee or occupant satisfaction can be substantial. A more comfortable working or learning environment leads to increased productivity, fewer complaints and potential health benefits from better indoor air quality. This is particularly important in health care and education, where comfort and safety are paramount.  

Upgrading HVAC control systems can significantly improve ROI by helping businesses comply with regulations, like Washington’s Building Performance Standards. These standards focus on energy efficiency and emissions reduction, aligning with broader sustainability goals. Modern DDC systems enable precise energy management, reducing waste and operational costs. By upgrading controls, companies can achieve compliance with local, state and federal regulations while benefiting from energy savings. Control system upgrades become the vehicle to meet these standards, ensuring long-term financial and environmental benefits for building operators.
