House Design

Dieppe Design is a certified Passive House Designer

As members of the Australian Passive House Association, we believe in designing smarter, healthier and more sustainable homes. As architects and designers, we have been given an opportunity to change the future and help build a better planet for the generations to come. In our view Passive House, or Passivhaus, is the best way to achieve this.

It is considered the most rigorous, voluntary building
standard in the design and construction industry. This methodology is more than window placement and cross flow ventilation. Passivhaus is a scientific assessment and results in a building that requires 90% less heating and cooling energy compared to a conventional building.

Sub urban and urban areas do not have the privilege to choose window placements, best cross ventilation and off grid living. Passivhaus can give residents in cities the benefit of clean living until the rest of the world catches up.

Why Passive House Design?

Passive House is a proven, tested and measured way of ensuring a healthy, sustainable, and economical home. Here are just some of the reasons we think it is the way to go:

  • Sustainability. Help reduce C02 emissions through sustainable building design.
  • Cost savings. Yes, the initial outlay will be more, but it is just a matter of mathematics: (initial outlay / energy savings per month = time it will take to pay itself back).
  • Almost complete off grid power. Saving up to 90% energy means most of the energy required to run appliances in the house can be achieved by off grid power.
  • No mould and improved air quality. Every Passive House is equipped with a heat recovery ventilation system. This sophisticated air circulation system supplies a constant stream of fresh air which is filtered and conditioned maintaining a relative humidity between 30% and 60%, replacing that stale, sticky atmosphere with one that feels fresh and clean.
  • Long lasting quality. To achieve the stringent quality guideline required for certification you can rest assured the quality of construction will be of high standard.
  • Comfort, in particular thermal comfort. We do the calculations to ensure that the internal air temperature is maintained between 20 degrees and 25 degrees throughout the year, without any heating or cooling! On top of that the high-performance building envelope means you can make as much noise as you want not disturbing the neighbours and vice versa.

There are five principals that a Passive House is designed and built under:

  1. Airtightness
  2. Thermal Insulation
  3. Mechanical Ventilation Heat Recovery (HVHR)
  4. High Performance Windows
  5. Thermal Bridge Free Construction
