In an era where sustainability is paramount, the 2021 International Energy Conservation Code (IECC) introduces stringent guidelines to enhance the energy efficiency of buildings. One of the key components of this code is Section C403.5, which pertains to economizers. Economizers play a pivotal role in regulating cooling systems in buildings, contributing to energy savings and environmental conservation.

The 2021 IECC is more than just a set of rules; it's a commitment to a greener, more energy-efficient future. Section C403.5 of the code focuses on economizers, a crucial element of heating, ventilation, and air conditioning (HVAC) systems. In this blog post, we'll delve into the specifics of economizers as outlined in the code, their significance, and when they are required.
