Understanding the significance of building energy codes and pathways for engagement empowers communities to participate in the development and implementation of building energy codes, contributing to broader goals of environmental sustainability and public health. Building energy codes offer significant benefits such as improved health, reduced utility costs, and environmental sustainability. However, it is a challenge to ensure that communities benefit equally, particularly for low-income households facing higher energy expenses and difficulties accessing energy-efficient housing. Communities can drive change by raising awareness about opportunities for public input and collaborating with state and local energy efficiency organizations and stakeholders. This brief outlines several ways that communities can actively engage in the process to develop and implement building energy codes and influence code changes that better suit their needs and priorities.
