Cincinnati’s summer heat is no joke, and as climate change brings warmer temperatures, finding sustainable and effective ways to keep our homes cool is more important than ever. That’s why Trilobite Design is thrilled to announce our collaboration with AIA Cincinnati for this year’s Ice Box Challenge at Cincinnati Homearama!
This isn’t your typical home show exhibit. In contrast to the LEED certified fancy houses next door, the Ice Box Challenge is about demonstrating the power of passive house design principles in a tangible, impactful way.
What is the Ice Box Challenge?
Two shed-sized boxes are constructed as if they were mini-homes. One is built to the code-minimum standards of airtightness, insulation, and thermal bridging. The other is built to Passive House levels of airtightness, insulation, and thermal bridging. Physically, they look the same, but the performance is what matters! The challenge is simple: keep a block of ice from melting for as long as possible, without any active cooling systems. Each building is started with a 1,000 lb block of solid ice and left to sit through the fall heat. In a couple of weeks, we’ll open them up, weigh the remaining, and dig into the building science about how and why the performance translates to better homes for people.
What are we trying to teach the public?
This challenge is more than just a fun competition; it’s an educational opportunity. We want to demystify the principles behind passive house design and show Homearama attendees how these strategies can translate into real-world benefits for their own homes.
Here’s what we’ll be highlighting:
- Super Insulation: Just like a well-insulated cooler keeps your drinks cold, a super-insulated home prevents unwanted heat from entering. We’ll be showcasing advanced insulation techniques and materials that go far beyond conventional building standards.
- Airtight Construction: Leaky homes are energy hogs. We’ll demonstrate the importance of meticulous air sealing to prevent drafts and heat transfer. Think of it as wrapping your home in a cozy, protective blanket.
- High-Performance Windows: Windows can be a major source of heat gain. We’ll be using cutting-edge windows with multiple panes, low-emissivity coatings, and insulated frames to drastically reduce solar heat gain while still allowing natural light in.
- Thermal Bridge-Free Design: Thermal bridges are like weak spots in your home’s envelope where heat can easily sneak in (or out). We’re designing our ice box to eliminate these pathways, ensuring a continuous thermal barrier.
Why does this matter to you?
The principles we’re showcasing in the Ice Box Challenge have direct and significant implications for your comfort, your energy bills, and the planet. By adopting passive house strategies, you can:
- Reduce your energy consumption: Lower your reliance on air conditioning, saving you money and reducing your carbon footprint.
- Increase your comfort: Enjoy a more consistent indoor temperature, free from hot spots and drafts.
- Improve indoor air quality: Airtight construction, when combined with proper ventilation, can lead to a healthier living environment.
- Build a more resilient home: A passive house is better equipped to handle power outages and extreme weather events.
We invite everyone attending Cincinnati Homearama to stop by the Ice Box Challenge exhibit, see the melting in action, and learn more about how sustainable architecture can transform your living space. An Architect be there to answer your questions and demonstrate how these principles can be applied to both new construction and existing homes.
