Deep Dive into Net Zero Water and the Water/Energy Nexus

February 25, 2021 @ 8:00 am - 10:00 am

The New England Living Building Collaborative is presenting a series of webinars on how water management, water efficiency and water and energy nexus concepts can be incorporated into project planning, design, construction and operation.

Deep Dive into Net Zero Water and the Water/Energy Nexus will explore how energy is involved with water by looking at the energy embodied in water infrastructure, and the energy available from water and how these can be utilized to contribute to an overall energy budget. The implications of embodied and operational carbon in the built environment water cycle will be addressed. Case studies to be included in this third workshop will include thermal extraction of water from reuse water in Manhattan. Additional case studies may include geothermal and extraction of thermal energy from sewers are still underdevelopment and will be announced as the workshop is refined.
