IECC Committee Passes New EV-Ready Code Requirements

May 28, 2019

The International Code Council (ICC) code hearings were held the first week of May in Albuquerque to determine which of the proposed code amendments will be considered for adoption in the 2021 model building code. Southwest Energy Efficiency Project’s (SWEEP) proposal to add electric vehicle (EV)-ready infrastructure requirements to the code was approved by the commercial International Energy Conservation Code (IECC) committee.

The proposed code will require new commercial and high-rise residential buildings to facilitate the easy and low-cost installation of future electric vehicle charging. The electric vehicle market is expanding quickly and from 2017 to 2018, EV sales in the US grew by over 80%. Yet the lack of access to charging infrastructure continues to be a critical barrier to EV adoption.EV charging station

The transition from gasoline to electricity as a transportation fuel offers many energy efficiency benefits. Not only are electric vehicles three times more energy efficient than gas cars, but the transition to electric transportation will increase grid efficiency by adding millions of flexible energy resources to the grid and charging them during off-peak demand periods. In addition, the Level 2, 240-volt charging stations this code would support, are more energy efficient than a typical Level 1, 120-volt wall plug. By facilitating charging in residential buildings, this makes both the electricity and transportation systems more energy efficient and less wasteful.

The committee’s approval is a positive first step toward adoption of EV capabilities in the IECC. The code must also pass the governmental consensus process later this year before it is formally adopted into the IECC. SWEEP partnered with New Building Institute, Edison Electric Institute, and Alliance to Save Energy to develop the code proposal. A similar proposal was submitted for new residential buildings, but was not approved by the Residential IECC committee.

A broad and diverse mix of 68 stakeholders supported the proposal through a letter of support which was distributed at the committee hearings. The stakeholders included consumer groups, automakers, EV charging companies, environmental organizations, electric utilities, clean energy companies, and public health and science advocates that strongly support EV adoption and improved building codes.

buildee, simuwatt's energy management and energy efficiency platform, is adding EV and electrification measures to its ever-expanding data library. Beneficial electrification is a term for replacing direct fossil fuel use with electricity in a way that reduces overall emissions and energy costs. buildee will now have integrated calculations on the energy savings potential of electrification measures like the EV-ready requirements that have passed IECC committee.
