LEED Zero and 4.1: The LEED We’ve Been Waiting For

August 14, 2019 @ 8:00 am - 10:00 am

$30 – $45

With the release of the LEED Zero suite of certifications (Zero Energy, Carbon, Water, and Waste), and with the evolution of LEED v4.1, we may have a series of rating systems that provide market-driving direction to lead the sustainability industry. In addition, LEED Zero finally bridges the gap between a great project (LEED Platinum) and the various definitions of Net Zero Energy (NZE) and Carbon that exist out there, and it creates alternate options for defining a great project (say, LEED Silver + NZE). They will also direct buildings to adopt solutions that are supportive of an electric grid that is taking on more and more renewable energy, and to consider their options for energy procurement, including contracting for meaningful offsite renewable resources.

This session will review v4.1 (BD+C) along with LEED Zero Energy and Carbon to provide an overview of the various changes, an introduction to the new tools and metrics, and will look at the applicability to a few different project types (e.g. urban high rise versus less dense and non-space constrained). It will also include a discussion and reflection of how well these rating systems capture the current need in the market or whether we should anticipate further changes in the years to come.

Learning Objectives:
Identify changes in LEED v4.1
Examine the definitions and challenges of Net Zero Energy, Water, and Carbon
Discuss how LEED v4.1 and LEED Zero work for various project types
Learn to love LEED again!
