The City and County of Denver released a comprehensive plan to achieve net zero energy (NZE) in new buildings and homes by 2030, one of many initiatives being taking to meet the jurisdiction’s goal of an 80% reduction in greenhouse gas (GHG) emissions by 2050. NBI worked with the City and County on a number of aspects including defining NZE building standards, engage stakeholders, and creating timelines for reaching NZE across a range of building stock types and categories. NBI’s work, which is part of the American Climate Cities Challenge, also examines the cost, equity and workforce implications in helping shape the plan.
