What is the purpose of the ACCA Manual S?

The ACCA Manual S is specifically designed for the selection of residential heating and cooling equipment. Its primary purpose is to provide guidelines and procedures for sizing and selecting HVAC (heating, ventilation, and air conditioning) equipment in residential settings. This ensures that the equipment operates efficiently and effectively, providing the necessary comfort levels for occupants while minimizing energy consumption. Proper equipment selection is crucial for maintaining indoor air quality and overall energy performance in buildings, which aligns with LEED goals.

By adhering to the guidelines in Manual S, HVAC professionals can ensure that the selected systems are appropriately sized for the home's specific heating and cooling loads. This helps not only in achieving optimal performance but also in supporting other aspects of green building practices, such as energy efficiency and sustainable design principles.
