When Old Buildings Meet New Standards: Energy Code Compliance Challenges
REGISTER HERE
EVENT INFORMATION
Building energy codes are becoming more stringent with respect to airtightness and insulation requirements for both new and existing buildings. While a new construction project can simply adjust dimensions and modify materials, it is more challenging for existing buildings to address enclosure performance, sustainability, accessibility, historic preservation, existing materials, cost constraints, and other existing conditions. Join us for this webinar where the presenters will share their experience exploring feasibility studies for energy upgrades and renovations to existing buildings, and how to balance competing project issues. This webinar will also explore strategies for collaborating with project team members to figure out ways for the existing enclosure to comply with project and local jurisdiction goals for energy performance.
Date: May 21, 2026
Time: 3:00PM
Location: Virtual
LEARNING OBJECTIVES
- Discuss recent modifications to energy codes for existing buildings.
- Understand the various items that should be considered (code considerations, energy performance, enclosure conditions, etc.) when exploring an existing building renovation.
- Contemplate strategies for meeting increased energy performance while keeping existing enclosures in place.
- Explore case studies from existing building renovations to understand how the project team can balance energy performance with other considerations (historic preservation, enclosure performance, owner constraints, etc.).
Participants will earn 1 AIA CES Learning Unit (LU/HSW) for attending the webinar.
