‍Decarbonize Now: LEED v5 Strategies for Ultra-Low Emission Buildings‍

‍November 4, 2025, from 8:00 AM - 12:00 PM PT and 1:00 PM - 5:00 PT

LEED v5 has been holistically created to guide decisions and actions to move us towards our global climate goals. This workshop focuses on the LEED BD+C rating system to provide steps and tools to deliver new buildings with ultra-low greenhouse gas emissions for operations. This workshop teaches the steps and tools for achieving decarbonization, focusing on the first step: operational decarbonization design and planning. It will highlight the LEED v5 “recipe” for achieving decarbonization. The workshop will provide an understanding of the importance and utility of decarbonization plans and how to establish these plans for new construction projects. Attendees will engage in a fun activity to model designs and factors and learn how to account for wild cards in a green building project.

Learning Objectives:

1. Recognize the benefits and strategies for operational decarbonization in new construction projects
2. Apply decarbonization design and planning actions
3. Identify steps and tools for achieving ultra-low operational greenhouse gas emissions in new buildings
4. Identify potential wildcards in decarbonization designing and planning

‍ASHRAE 209: Updates and How to Use for LEED V5‍

‍November 6, 2025, 2:30 PM to 3:30 PM PT

ASHRAE Standard 209, "Building Performance Simulation Process," sets procedures for using energy modeling to quantify design decisions' impact. It establishes minimum requirements for energy design assistance using building energy simulation and analysis, aimed at building owners and architects seeking a uniform way to specify a scope of work for energy modeling. In this session, three ASHRAE 209 Committee members will describe the standard and provide real-life examples of how it fosters an integrative design process incorporating energy simulation. Over the past 20 years, energy simulation has grown, but many projects still perform “validation” modeling post-design. The true value of energy models lies in influencing design decisions. Architects and owners often struggle to create a scope of work for early “design assistance” modeling. ASHRAE 209 offers the necessary language for owners and architects to specify the required modeling scope, ensuring competing proposals can be assessed "apples to apples." ASHRAE 209 supports energy modeling as part of an integrative design process, defining 11 different "cycles" of energy simulation a project might incorporate, from simple box models in concept design to as-built models in measurement and verification. Additionally, ASHRAE 209 can be a valuable tool for projects pursuing LEED BD+C v5 certification, particularly in the Integrative Process credit. Early design assistance, consistent scope of work, carbon reduction modeling, future weather data, and potential innovation through pilot credit are all aspects of ASHRAE 209 that align well with LEED BD+C v5's goals. Integrating ASHRAE 209 into the LEED BD+C v5 framework can enhance energy modeling practices, ensuring more accurate and impactful sustainability outcomes.
