2024 International Energy Conservation Code (IECC)

The energy code is where a building’s operating cost is decided, years before anyone pays a utility bill. The 2024 International Energy Conservation Code sets the minimum envelope, systems and lighting performance that new construction and major renovation must meet, and it is the code most often missed until a plan review sends the drawings back.

What the code covers

• Separate residential and commercial provisions in a single volume
• Building thermal envelope: insulation, fenestration, and air leakage requirements
• Climate zone tables and how they change the numbers for your location
• Mechanical system efficiency, ductwork, and equipment sizing
• Service water heating, lighting power allowances and controls
• Compliance paths: prescriptive, performance, and the ERI option

Who it’s for

Architects, mechanical and energy engineers, HERS raters, building officials, and builders who need to demonstrate energy compliance at permit.
