Passive House Design in Perth and Margaret River

A Passive House is designed and constructed to achieve unparalleled energy efficiency and indoor comfort. Unlike traditional homes, Passive Houses prioritize airtightness, superior insulation, high-performance windows, and heat recovery ventilation systems to drastically reduce energy usage while maintaining a consistent and comfortable indoor temperature year-round.

Absolutely. Passive Houses are highly adaptable and can be optimized for Perth's hot summers and mild winters, or Margaret River’s generally more mild climate. Using smart shading, ventilation strategies, and thermal mass, a Passive House in Perth or Margs can remain comfortable while drastically reducing reliance on air conditioning.

While the upfront cost of a Passive House can be slightly higher due to specialized materials and systems, the energy savings over time often outweigh the initial investment. Passive Houses also benefit from lower maintenance costs and improved property value due to their superior performance and sustainability credentials.

Passive Houses can be built using a variety of materials, including timber, concrete, and brick, provided they meet the high-performance standards for insulation and airtightness. Locally sourced and sustainable materials are often prioritized to reduce environmental impact.

The process varies depending on the size and complexity of the project, but on average, a Passive House takes several months to design and 12-18 months to complete the build.

While Passive House is ideal for new homes, we also offer retrofitting services to help improve the energy efficiency of existing homes, reducing energy consumption and enhancing comfort.

Yes, it’s possible to retrofit an existing home to meet Passive House standards through a process known as EnerPHit. While it can be more challenging than building new, retrofitting includes improvements like upgrading insulation, windows, and ventilation systems to enhance energy efficiency and comfort.

Passive Houses are certified by the Passive House Institute, which verifies that the design and construction meet rigorous performance criteria. This includes energy demand limits, airtightness levels, and thermal comfort metrics. Working with a certified Passive House designer, like Cynosure Architecture, ensures your project aligns with these standards. A third party assessor certified by the passive house institute will also be required to confirm and administer the eventual certification for the home.

A Passive House employs a heat recovery ventilation (HRV) system that continuously exchanges stale indoor air with fresh outdoor air while maintaining comfortable temperatures. This system filters out allergens, pollutants, and excess moisture, resulting in a healthier indoor environment.

Passive Houses typically eliminate the need for traditional heating and cooling systems. Instead, they rely on passive solar gain, insulation, and heat recovery ventilation to maintain comfortable temperatures. However, in extreme climates like Perth’s summer heatwaves, a small supplementary system may be required and used sparingly.

Building a Passive House in Perth or the South West offers numerous benefits, including lower energy bills, reduced carbon footprint, enhanced thermal comfort, and improved indoor air quality. Additionally, Passive Houses contribute to sustainable development goals and provide resilience against rising energy costs.
