Potential changes to commercial building code 

A proposal has been made to the International Energy Conservation Code that would change the ways commercial buildings are constructed, potentially cutting energy costs by 25%.


Proposed changes to the International Energy Conservation Code (IECC) have been made that would adjust the standards for commercial buildings, making them 20% to 25% more energy efficient . The proposal is being reviewed by the International Code Council .

Created by the New Buildings Institute (NBI) and the American Institute of Architects , the code changes focus on achieving carbon neutrality in buildings by 2030. This means adjustments to five aspects of a structure: building envelope, heating/cooling, lighting, quality assurance, and renewable power.

Within the proposal are several details about what the new IECC would state. Windows and doors would be specified to create insulation while eliminating excess heat, reducing HVAC costs. Efficient light fixtures and bulbs, as well as occupancy and daylight sensors, would be required as a way to save energy. And renewable energy would be required as a source of power in the building.

The proposal is based off a previous energy saving standard created by the NBI, Core Performance. Commercial building codes based on Core Performance have already been adopted by Massachusetts and are under consideration by other states and municipalities.
