Topic
HVAC Design Level 2 (ADEG Explanation)
HVAC design lies at the heart of building efficiency, necessitating strict adherence to established standards. ASHRAE 90.1 stands out, providing a comprehensive foundation for energy standards within buildings and guiding HVAC system designs tailored to specific applications. Complementary to this is ASHRAE 62.1, which focuses on ventilation for indoor air quality, specifying the necessary volume of outdoor air for various spaces. ASHRAE 55 further contributes by setting guidelines for thermal environmental conditions conducive to human occupancy. Advanced engineering design guides, aiming for energy savings up to 70% against traditional designs, serve as crucial tools for designers. These guides, coupled with adherence to standards like ASHRAE 90.1, ASHRAE 62.1, and ASHRAE 55, are indispensable in achieving high-performance, energy-efficient buildings.
Variable Refrigerant Systems and Applications

Since their market introduction in the 1980s, variable refrigerant systems have showcased significant energy savings and compatibility, solidifying their position within the industry. Recognizing their importance, ASHRAE introduced specific standards and guidelines, including the notable ASHRAE 41 guideline of 2020, to govern their application. This global embrace of variable refrigerant technology highlights the critical need for adherence to established design and selection practices, guided by safety standards and limits detailed in ASHRAE 34 and ASHRAE 15. These standards ensure the safe and efficient utilization of variable refrigerant systems, promoting their continued success in the industry.

Energy Auditing in Building
Energy auditing is a pivotal strategy in the global energy efficiency agenda. The ASHRAE 100 standard offers a structured framework for conducting energy audits in commercial buildings, detailing a three-level approach. This standard serves as a comprehensive guide, facilitating the identification and implementation of energy-saving measures. Energy audits, as outlined in the ASHRAE 100 standard, are essential in optimizing energy use in buildings, playing a critical role in mitigating global energy consumption challenges.
