Net zero energy has been the north star for high-performance buildings for more than ten years, but the target is quickly shifting to net zero carbon. This change in definitions might seem abstract, but it drives real changes for building designers, owners, efficiency programs, regulators, and others. In this session, a panel of buildings industry market leaders will present key zero carbon building goals, standards, and programs. These include USGBC's LEED Zero program, ASHRAE Standard 228p (zero net energy and zero net carbon building performance evaluation), ULI Greenprint Center's Net Zero Carbon goals, and NBI's Getting to Zero building database tracking and analysis. This panel will discuss key frameworks, definitions, and market implications of today's shift from zero energy to zero carbon buildings.
