(B-6) Low Energy to Net Zero: The New Normal

Nautilus 1

A new generation of health care buildings are demonstrating that a universal net zero, carbon-neutral future can be a cost-effective reality today. This session will connect attendees with case studies from some of most energy efficient health care projects in North America, as presented by the involved architecture and engineering firms, as well as the facilities director for a California academic medical center with a 2025 carbon neutrality goal. The projects span the acute care and ambulatory environments and incorporate the technologies and energy strategies needed to meet the level of energy performance required for net zero and carbon-neutral design.

The case study projects have all achieved at least a 40 percent energy reduction and incorporate alternative energy systems. One such case study is the Lucile Packard Children’s Hospital Stanford: the first hospital in North America to include a displacement ventilation system. The session will outline the steps implemented and include an overview of how to model passive design strategies in tandem with alternative HVAC system options while ensuring informed decision-making and budget alignment. The presenters will draw from their personal experience in leading these projects to share the lessons learned, common roadblocks, and paths forward. It will conclude with a discussion on what a net zero emission hospital and campus will look like as demonstrated by recent project studies completed for a large California based health system.

These examples highlight how low energy and net zero health care buildings require a fundamentally different approach that reconsiders conventions from site, to envelope, and beyond. Attendees will leave the session with a better understanding of the state of the market and a greater confidence they’re able to achieve a deeper level of energy efficiency and carbon reduction today.
