The Code Corner explores sections of the International Codes® each month, focusing on key elements of these essential codes. This month, we’re spotlighting the scope of Chapter 3 of the 2024 International Fuel Gas Code®.
Improving Predictability in Code Compliant High-Performance Wall Assemblies
Assemblies that reduce conductive attachment pathways tend to deliver more predictable performance, lower heat loss, and reduced moisture risk.
Continuous insulation (CI) is now widely recognized as a foundational strategy for improving the thermal performance of commercial buildings. Energy codes increasingly rely on CI to reduce heat flow through exterior walls….
Low‑Ambient Derating in Heat Pumps: Capacity Loss and Balance‑Point Calculation for Auxiliary Heat Requirements
The derating curve is not merely a performance characteristic, it is a design tool that shapes equipment selection, auxiliary heat sizing and overall system architecture.
Heat pump technology has become a defining component of modern HVAC engineering in regions of the country where buildings are transitioning toward electrification and higher efficiency. Although all heat pumps…
