In this episode of Home Green Homes, Izumi Tanaka talks with Nick Grimm — a father, homeowner, and sustainability professional who is gradually transforming his 1953 Los Angeles home into a healthier and more energy-efficient space.

Nick didn’t begin with a master sustainability plan. Like many homeowners, his journey started with basic maintenance: replacing appliances when they broke and making upgrades when necessary. But as he learned more about sustainability, each decision became an opportunity to choose better options.

So far, Nick and his family have:

• Replaced a gas cooktop with an induction stove
• Installed a heat pump washer/dryer
• Upgraded their electric panel
• Installed solar panels
• Purchased an EV and charger
• Begun planning for heat pump HVAC and water heating
• Started thinking about drought-resilient landscaping

One turning point came when Nick used an indoor air quality monitor while cooking on a gas stove — and saw pollution levels spike inside his home. With a young child experiencing asthma, it accelerated their switch to induction cooking.

Nick also discusses the real barriers to electrification, including the complexity of rebates and the financial realities many homeowners face.

Despite those challenges, he believes individual choices still matter. For Nick, the ability to take action — even one appliance at a time — is empowering.

If you're a homeowner wondering whether it’s time to replace gas appliances with electric alternatives — this episode is for you.

In Episode 102 of Home Green Homes, Izumi chats with Akanksha Mathur, General Manager for Southern California at Elephant Energy, to discuss what it really takes to electrify your home.

From heat pumps and induction cooking to rebates, incentives, and indoor air quality — we break down the electrification process step-by-step.

Elephant Energy is a Certified B-Corp focused on making the switch from gas to electric simple, seamless, and climate-friendly. Akanksha shares her journey from mechanical engineer to climate advocate, and why education is the missing link in helping homeowners make confident decisions.

If you live in Southern California — or anywhere thinking about clean energy upgrades — this conversation will help you understand:

• What “home electrification” actually means
• How heat pumps work
• What incentives are available
• Why indoor air quality matters
• The biggest challenges homeowners face
• How to make sustainable choices easier

The future is electric. The question is — are you ready?

What does it really take to build homes that are beautiful, efficient, resilient, and responsible?

In this special 100th episode of Home Green Homes, Izumi Tanaka welcomes Steve Glenn, founder and CEO of Plant Prefab, for an in-depth conversation that weaves together architecture, sustainability, entrepreneurship, and climate action.

Steve traces his path from an early love of architecture to founding LivingHomes and later Plant Prefab—companies created to challenge the waste, inefficiency, and environmental impact of conventional construction. He explains what truly sets Plant Prefab apart: customized architectural design, a purpose-built factory capable of both panelized and modular construction, and a mission-driven commitment as a certified B Corp and public benefit corporation.

The conversation also dives into Plant Prefab’s work supporting communities rebuilding after devastating Southern California wildfires, and why prefab construction can offer faster, more predictable, and often more cost-effective rebuilding solutions.

Along the way, Steve addresses common misconceptions about prefab homes, shares what homeowners should prioritize when designing for climate resilience, and reflects on leadership, scaling a values-driven company, and what he hopes the future of housing can become.

This episode is especially relevant for homeowners, home dwellers, architects, builders, developers, and anyone curious about how housing can be part of the climate solution.

• Prefab ≠ mobile homes: Plant Prefab homes are legally and structurally equivalent to site-built homes and cannot be excluded from zoning, financing, or insurance.
• Energy matters most: Over a home’s lifetime, operational energy use has a bigger climate impact than materials—efficiency and solar should be top priorities.
• Time is money: Faster, parallel construction can significantly reduce carrying costs, rent, and uncertainty—especially important in rebuild scenarios.
• Design and sustainability go together: High-quality architecture and environmental responsibility are not mutually exclusive.
• Rebuilding after disaster is an opportunity: Prefab can help communities recover faster while building more resilient, future-ready homes.
• Mission-driven businesses face real challenges: Scaling sustainably takes persistence, patience, and long-term vision—but the impact compounds over time.
