This is a tale of two companies on a quest to account for the embodied carbon impacts of energy retrofits, and to incorporate these impacts into the project planning process. How do we decide when embodied emissions are worth longer-term emission reductions? What are the pros and cons of choosing lower embodied carbon materials compared to higher emission ones? How do carbon-smart choices relate to other project goals and requirements?  The speakers will address these questions through case studies and will share measured savings for projects with at least one year of pre and post retrofit energy use data, and modeled savings for projects without this data. By considering operational and embodied carbon impacts, we can optimize our practices to realize deep climate impact reductions.
