Bomee Jung is co-founder/co-CEO of Cadence OneFive, a public benefit corporation with a climate justice mission. They are developing, Momentum, a software to enable city-scale acceleration of existing building decarbonization. Before this role, Bomee was the first VP for Energy and Sustainability at the New York City Housing Authority (NYCHA), and before that she led the climate mitigation and adaptation programs of the New York office of Enterprise Community Partners. She serves on the board of the Institute for Market Transformation and the loan committee of Capital For Change. With Momentum, Bomee and her co-founder and team are focused on change at scale. “We deliver a way for owners to understand their options around climate response, using building science and climate data,” she says. Instead of the bespoke consulting service model, the Momentum team proposes that many owners with conventional properties can benefit from a dataset-empowered playbook. “There are lots of options for doing climate responsive construction today. This is a way for people to understand methods and technologies, not just about emissions but also about housing quality and other factors.” Bomee suggests that the industry is facing a traditional tragedy of the commons problem. Sharing information could generate broad positive impact. With construction pricing, for example, sharing fresh information widely could rapidly reduce risks for many. This is where software has a unique role: “These are known problems and we offer transparency to help solve them.”
