According to the World Health Organization, chronic obstructive pulmonary disease (COPD) is a leading cause of death globally, responsible for more than 3 million deaths every year1. Given this substantial disease burden, early and accurate diagnosis is essential for effective prevention and long-term management. The GOLD 2024/2025 reports emphasize that spirometry is required to establish the diagnosis of COPD, with a post-bronchodilator FEV1/FVC < 0.7 serving as the defining criterion for persistent airflow limitation in the appropriate clinical context2.

When working with demand control ventilation (DCV) systems, it is essential to comply with Title 24, California's Building Energy Efficiency Standards. Title 24 sets various requirements for building design and construction to reduce energy consumption and improve indoor air quality (IAQ). Title 24 mandates the adoption of DCV systems for new and renovated buildings in California, drawing significant attention to DCV implementation. This article provides insights into Title 24 and offers solutions for compliance.
