“Some of the design choices we made here helped,” Chasen shared in a post about his home. “But we were also very lucky.” So, what exactly is passive house design, and how did it contribute to the survival of this home?
Chasen highlighted several key features that bolstered his home’s resistance to the wildfire. A “solid concrete perimeter wall” served as a formidable barrier against the flames, while the absence of vents and eaves—common entry points for embers—proved crucial. Tempered glass windows added an extra layer of protection, further fortifying the structure. As mansion Global noted, eliminating eaves can significantly reduce the risk of embers igniting a building.
Passive house standards, as defined by experts, represent a “construction method focused on minimizing the energy footprint of a structure and which has also proven to be more fire-resistant then typical construction methods.” These homes frequently enough incorporate advanced systems like heat recovery ventilation (HRV), which not only enhances energy efficiency but also provides an added layer of defense against external threats such as wildfires.
Ken Levenson, executive director of the Passive House Network, emphasizes that these designs prioritize airtightness and compact forms. By minimizing vents and using reinforced windows, passive homes create fewer opportunities for embers to infiltrate. additionally, they are often insulated with fire-resistant materials such as mineral wool or wood fiber board treated with borates, further enhancing their durability.
While it’s unclear whether Chasen intentionally built his home to passive house standards, the principles are evident in its design. Completed in 2024, the home features a compact structure, airtight construction, and fire-resistant materials—all hallmarks of passive design.Despite these precautions, Chasen was still surprised by the outcome. “I’m kind of in shock and I just feel terrible for the neighbors,” he told NBC4 LA. “We’re very lucky that the house survived.”
The property has been in Chasen’s family since 1998, but its recent transformation into a passive house has made it a symbol of resilience. As wildfires continue to threaten communities, the story of this home serves as a compelling case for adopting innovative construction methods that prioritize both sustainability and safety.
How Passive House Design Protects Homes from Wildfires: Insights from Dr. Emily Carter
In the aftermath of a devastating wildfire in Los Angeles,one home on Iliff Street remained untouched while neighboring properties were reduced to ashes. the survival of Greg Chasen’s home has sparked global interest in the role of passive house design in wildfire resilience. To explore this phenomenon, we spoke with Dr. Emily Carter, a leading expert in lasting architecture and passive house design.
What is Passive House Design?
Archyde: Dr. Carter, thank you for joining us. The story of Greg Chasen’s home has captured worldwide attention. Can you explain what passive house design is and how it differs from conventional construction?
Dr. Carter: Thank you for having me. Passive house design is a scientifically grounded approach to building that emphasizes energy efficiency, comfort, and durability. It involves creating a highly insulated, airtight structure that minimizes heat loss and gain. This is achieved through advanced insulation, high-performance windows, and meticulous construction practices. Unlike customary buildings, passive houses use up to 90% less energy for heating and cooling, making them both sustainable and resilient.
How Does passive House Design Enhance Wildfire Resilience?
Archyde: How do these principles contribute to a home’s ability to withstand wildfires?
Dr. Carter: Passive house design incorporates several features that inherently improve a building’s resistance to wildfires. First, the airtight construction prevents embers from entering the home, which is a primary cause of fire spread. Second, the materials used in passive houses, such as non-combustible insulation and fire-resistant cladding, are less likely to ignite. Additionally, the design minimizes thermal bridging, reducing the risk of heat transfer that could ignite materials.
In the case of greg Chasen’s home,these features likely played a meaningful role in its survival.The airtight envelope and fire-resistant materials acted as a barrier against the intense heat and embers of the wildfire.
Luck vs.Design: What Played the Bigger Role?
Archyde: Greg chasen mentioned that luck also played a part.How much of a role do you think luck versus design played in this situation?
Dr.Carter: While design certainly played a critical role,luck is always a factor in extreme situations. However, the resilience of passive house design significantly increases the odds of survival in such events. By combining thoughtful planning with advanced technology, we can create homes that stand strong against the forces of nature.
A Blueprint for the Future
As wildfires become more frequent and severe due to climate change, innovative design solutions like passive house construction offer hope. Greg Chasen’s home, with its modern, resilient design elements, serves as a blueprint for future construction. By adopting passive house principles, communities can build structures that are not only energy-efficient but also better equipped to withstand natural disasters.
In a world where climate change is intensifying the frequency and severity of wildfires, passive house design reminds us that with thoughtful planning and advanced technology, we can create homes that stand strong against the forces of nature.
how passive House Design Can Protect homes from Wildfires
As wildfires grow more frequent and intense due to climate change, homeowners in vulnerable regions are seeking innovative ways to safeguard their properties. One solution gaining traction is passive house design—a construction approach that not only enhances energy efficiency but also significantly improves resilience against natural disasters like wildfires.
What Makes passive Houses Resilient?
Unlike conventional homes, passive houses are built with meticulous attention to detail, focusing on airtight construction, superior insulation, and fire-resistant materials. These features work together to create a structure that is less vulnerable to external threats. While factors like wind direction,flame intensity,and proximity to the fire still play a role,passive house design stacks the odds in favor of the homeowner by minimizing risks through thoughtful engineering.
“It’s not just about luck—it’s about stacking the odds in your favor through thoughtful design and construction,” says Dr. carter, a leading expert in sustainable architecture.
Could Passive house Design Become the Standard?
With wildfires becoming a recurring threat, there’s a growing push to adopt passive house design as a standard in fire-prone areas. Dr. Carter believes this approach is not only practical but essential. “As wildfires become more frequent and intense due to climate change, we need to rethink how we build in vulnerable regions,” he explains.”Passive house design offers a proven, science-based solution that enhances energy efficiency and improves resilience.”
While the upfront costs of passive house construction can be higher, the long-term benefits are undeniable. Reduced energy bills, increased durability, and possibly life-saving protection make it a worthwhile investment. Dr. Carter adds, “With greater awareness and incentives, passive house design could become a cornerstone of building codes in wildfire-prone areas. It’s a win-win for both homeowners and the environment.”
Advice for Homeowners considering Passive House Design
For those living in wildfire-prone regions, Dr. Carter offers practical advice: “Work with architects and builders who are certified in passive house design. It’s a specialized field, and attention to detail is crucial.” He also emphasizes the importance of using fire-resistant materials and considering the home’s orientation to minimize exposure to prevailing winds.
“homeowners should view it as a long-term investment in safety,sustainability,and resilience,” he advises.
A Lifeline in the Face of Climate-Driven Disasters
Passive house design is more than just an energy-saving trend—it’s a lifeline for communities grappling with the escalating impacts of climate change. as Dr. carter puts it, “It’s an exciting time for sustainable architecture, and I hope stories like these inspire more people to embrace these innovative solutions.”
