2025 BES Session: The Retrofit Dilemma: Balancing Deep Energy Goals with the Reality of an Existing Building (Hogan)

Course Overview
This session was originally presented at the 2025 IIBEC Building Enclosure Symposium in St. Louis, Missouri.  This course includes the following components:

• recording of the live session
• a summative assessment consisting of 10 multiple-choice questions
• two surveys required to claim continuing education credit

Description

How far can we push the limits of an existing building to achieve significant energy and carbon savings while navigating the constraints of its structure and function? This presentation will delve into the challenges of pursuing a deep energy retrofit for a high-rise residential building, with the goal of achieving EnerPHit certification. We will examine the design decisions, construction challenges, and necessary compromises made throughout the project, highlighting the delicate balance between ambitious energy targets and the practical realities of working with an existing building. By sharing lessons learned, this presentation aims to provide insights for other design professionals facing similar challenges.
