Passive House Wins: Top High-Performance Trends of 2024

As 2024 winds down, we’ve been reflecting on a great year—and, true to form, diving into the data! We analyzed this year’s blog posts to uncover the “hottest high-performance topics of 2024.”

The big trend we discovered is that readers are eager to learn how to conserve energy, improve thermal performance, and cut costs at home. Innovations in window technology and reducing reliance on natural gas sparked particular interest, signaling that 2025 could be a great year for increased awareness of Passive House principles.

1. Goodbye Gas Line: How the Collins-Ruddy Residence Reduced Their Reliance on Natural Gas

Todd Collins and his family have been on a multi-phase journey to retrofit their home in Golden, Colorado, aiming to get as close to net zero as possible—all while maintaining a comfortable living environment.

In this article, we explored the latest step in their sustainability journey: replacing their water heater and furnace and capping their gas line. We dive into the details of their new water heater, what drove their decisions, how they approached the upgrade, and whether it’s delivering the results they hoped for.

Todd practices what he preaches about embracing Passive House principles, and his family’s decision to make this change came down to several key factors:

• Achieve their goal of net zero energy and reduce fossil fuel use
• Eliminate environmental and safety risks (no gas = no carbon monoxide danger)
• Lower utility costs by relying more on solar power
• Taking advantage of timing, as the old water heater was due for replacement
• Relocate the water heater to a more efficient spot in the home for better thermal performance.

The result was a resounding success! Their family of four, including two teenagers, has seamlessly transitioned to the new system. This upgrade has improved their home’s energy efficiency while enhancing their quality of life and peace of mind.Curious about the products Todd used and how he made it all happen? Check out the full story of how the Collins-Ruddy residence capped their gas line and took another step toward sustainability.
