  1. Dutch startup Respyre makes moss grow directly on concrete building facades. No soil, no irrigation, no pruning. The moss lives on rainwater and humidity.

    A 2025 lab study found moss barriers achieve 41% PM2.5 and 47% PM10 reduction. Field tests captured 45,580 particles per mm2 on moss surfaces.

    Compared to algae bioreactor facades (Hamburg's BIQ house) and ventilated moss filters (CityTree), plus UCL's BiotA Lab panels. A survey of the whole field.

  3. ♻️ Il vetro riciclato entra nella stampa 3D: da scarti a facciate su misura, più leggere e sostenibili. L’edilizia guarda a un futuro trasparente. #Innovazione #GreenBuilding

  4. Mexican builder Omar Vázquez Sánchez uses sargassum seaweed for bricks, insulating homes naturally. How can we scale up this approach for wider use in sustainable building projects? #GreenBuilding #SustainableMaterials #EcoTech

  5. It seems like we are paying quite the premium for installing #ExteriorFoamInsulation, which is apparently fairly rare in residential applications, despite seeming simple to install and ideal for older houses built without the 2x8 rafters that would otherwise be needed to hold enough insulation.

    Here's hoping our investment in the technology will make things marginally simpler for other sustainably-minded homeowners in the future.

  7. Heat Recovery Ventilator (HRV) — Operating Principle

    A recuperator (heat recovery unit) transfers heat from exhaust air to incoming fresh air without mixing the two streams.

    ---

    How It Works

    Two airflows:

    Exhaust air (warm, from indoors)

    Supply air (cold, from outside)

    They pass through a heat exchanger:

    separated by plates or channels

    no direct mixing

    heat transfers through the material (conduction)

    Result: → supply air is preheated
    → exhaust air is cooled
    → overall heat loss is reduced

    ---

    Types of Recuperators

    1. Plate Heat Exchanger

    aluminum or plastic plates

    efficiency: ~60–90%

    no moving parts

    2. Rotary (Wheel) Heat Exchanger

    rotating drum

    transfers heat and some moisture

    efficiency: up to ~85–90%

    3. Counterflow Heat Exchanger

    air streams move in opposite directions

    highest efficiency: up to ~95%

    ---

    What Is Transferred

    heat (primary)

    sometimes moisture (in enthalpy units)

    ---

    Efficiency Example

    outside: 0°C

    indoor: +22°C

    after recovery: ~16–20°C

    ---

    Advantages

    reduced heating energy demand

    continuous ventilation without major heat loss

    improved indoor air quality

    ---

    Limitations

    frost formation in winter (needs bypass or preheater)

    filter maintenance required

    upfront cost

    ---

    Core Idea

    A recuperator doesn’t generate heat — it recovers and reuses it.

  8. Bamboo plantations can store up to 250 tons of carbon per hectare, comparable to a forest, but achieved in a fraction of the time. It's a logistical win. What are the scalability hurdles for widespread bamboo plantation adoption? #GreenBuilding #SustainableMaterials

  9. Mycelium-based building materials are low-carbon, fire-resistant, and regenerative. What makes them a viable alternative to traditional construction? #SustainableMaterials #EcoFriendly #GreenBuilding

  10. Earth Tube Systems can slash energy costs by up to 50% by harnessing the ground's stable temperature. It's a practical way to reduce HVAC reliance, saving money and lowering your carbon footprint. How can we scale this tech for widespread adoption? #EnergySaving #GreenBuilding #EcoFriendly

  11. Cutting energy consumption by up to 75% with green roofs? That's the impressive result of a well-designed green roof, as research from the National Research Council of Canada reveals. From Bosco Verticale in Milan to the Vancouver Convention Centre, public buildings are now embracing green roofs as a key strategy for reducing environmental impact and enhancing urban biodiversity. But what's the real-world impact of these initiatives? #GreenBuilding #GreenTechnology #EnergySaving

  20. High-performance residential projects don’t have to cost more or slow construction.

    We help residential and multifamily developers deliver energy-efficient, LEED-ready homes through sustainable project management and practical, real-world execution.

    Our work is grounded in regenerative design principles informed by Indigenous ecological knowledge — applied in ways that support performance, resilience, and long-term value.
