The built environment generates almost 50% of global CO2 emissions.
Architects, engineers, and building owners must work together and commit to net zero emissions by 2030 to reduce the impact on climate change as specified by various climate and decarbonization initiatives. This necessitates architects design buildings that integrate energy efficiency and mitigate fuel sources that contribute to CO2 emissions into the design process to deliver buildings that are efficient, resilient, and carbon neutral as well as benefit diverse communities.

The presentation will discuss how to align design metrics and measures with energy and carbon reductions goals to meet benchmarking ordinances and other industry requirements. Participants will also learn what metrics are being mandated and which tools to use for evaluating energy design efficiencies that align with intended building performance outcomes.

This session will also share a case study from the US Environmental Protection Agency’s (EPA) ENERGY STAR Decarbonize Your Design Challenge highlighting best practices and challenges on a major renovation for Crossfield Elementary School in Fairfax County, VA. The presentation will share how architects can be recognized by EPA for designing buildings for future resiliency, diverse communities, and decarbonizing the built environment to move the next generation of buildings to zero carbon emissions.

Learning Objectives:

  • Understand how metrics from ENERGY STAR Portfolio Manager tool can help you align design metrics with performance outcomes
  • Understand Building Performance Standard being legislated in many cities and states and how they relate to energy design targets
  • Understand about Crossfield Elementary major renovation challenges and best practices to meet energy and CO2 reduction goals
  • Understand the ENERGY STAR Decarbonize Your Design Challenge call to action to decarbonize new construction and major renovation projects and opportunities by A/E firms to be recognized by EPA
