At Imagine Architecture, we pride ourselves on pioneering sustainable and energy-efficient building practices. Led by Tony Biesiek, a Certified Passive House Designer, our team brings unmatched expertise and a passion for creating homes that are as environmentally responsible as they are comfortable and cost-effective.

Tony's certification as a Certified Passive House Designer means that you can trust Imagine Architecture to deliver homes that meet the highest standards in energy efficiency and sustainability. With a keen eye for detail and a commitment to excellence, Tony ensures that every project incorporates the core principles of Passive House design, resulting in homes that are not only beautiful but also incredibly efficient.

What is Passive House?

Passive House (or Passivhaus) is an advanced standard in energy-efficient building design, focusing on creating homes that require minimal energy for heating and cooling. Originating in Germany in the late 1980s, the Passive House concept is centered on rigorous principles to ensure buildings are exceptionally well-insulated, airtight, and use highly efficient windows and ventilation systems. These homes are designed to maintain a consistent, comfortable indoor climate year-round with minimal energy input.

Key Principles of Passive House


  1. Thermal Insulation: Passive Houses have excellent thermal insulation, significantly reducing heat loss in winter and heat gain in summer.

  2. Airtight Construction: A continuous airtight layer prevents drafts and enhances energy efficiency.

  3. High-Performance Windows: Double glazed or triple-pane windows with insulated frames minimize heat transfer and maximize natural light.

  4. Mechanical Ventilation with Heat Recovery (MVHR): This system ensures fresh air circulation while recovering heat from exhaust air, maintaining indoor air quality and reducing heating and cooling demands.

  5. Thermal Bridge-Free Design: Structural elements are designed to avoid thermal bridges, eliminating cold spots and enhancing energy performance.

  6. Solar Gain Utilization: Buildings are oriented and designed to maximize solar heat gain in winter while minimizing overheating in summer.


Why Choose Passive House for Your New Home?

Unmatched Energy Efficiency

A Passive House uses up to 90% less energy for heating and cooling compared to conventional buildings. This substantial reduction in energy consumption translates to significantly lower utility bills and a smaller carbon footprint, making it an environmentally responsible choice.

Superior Comfort

The design principles of Passive House ensure a stable and comfortable indoor temperature throughout the year. The high insulation levels and airtight construction eliminate drafts and cold spots, providing a consistently cozy living environment. Advanced ventilation systems also ensure a steady supply of fresh, filtered air, enhancing indoor air quality and health.

Cost-Effective in the Long Run

While the initial construction cost of a Passive House can be higher due to the quality of materials and advanced design techniques, the long-term savings on energy bills and maintenance make it a financially wise investment. Moreover, as energy prices continue to rise, the value of an energy-efficient home becomes increasingly apparent.


Building a Passive House is a proactive step towards sustainable living. By drastically reducing energy consumption, Passive Houses contribute to the reduction of greenhouse gas emissions and reliance on fossil fuels. Choosing a Passive House aligns with global efforts to combat climate change and promote sustainable development.


As energy efficiency standards and building codes become more stringent, Passive House certification ensures that your home is ahead of the curve. This future-proofs your investment, making it easier to meet or exceed future regulatory requirements and enhancing the resale value of your home.

Enhanced Resilience

Passive Houses are built to be resilient against extreme weather conditions. The robust construction methods and materials provide superior durability and longevity, protecting your home from external elements and reducing the need for frequent repairs and maintenance.


Choosing a Passive House for your new home is a smart investment in energy efficiency, comfort, and sustainability. With Tony Biesiek of Imagine Architecture leading the way as a Certified Passive House Designer, you can trust that your home will meet the highest standards of energy performance and environmental responsibility.
