All the life changing benefits from our H4 High Performing Homes, plus more.

Every H4 PassivHaus Home is designed and built using the international PHI software. Performance is Measured, Proven and Tested.

The world needs affordable living and working environments with ultra-low energy consumption and minimum CO2 emissions.

What is a “PassivHaus” Passive Home?

Passivhaus is a concept developed in Germany that is being adopted and proven worldwide. Passive homes have a goal of increasing a building’s energy efficiency and reducing its ecological footprint. Buildings constructed to “PassivHaus” standard are ultra-low energy buildings: they use very little energy for heating or cooling and are extremely comfortable and healthy to live in.

A passive certified home, uses The International Passive House Standard, homes must meet a set of verifiable criteria set by the PassivHaus Institute (PHI).

How is this achieved?

5 KEY ELEMENTS that have been identified regardless of home design / budget / climate zone, in order to produce the world’s best building & living standard.

  • Quality Glazing

  • Thermal Efficiency

  • Air Tightness

  • Continuous Insulation

  • Ventilation

H4 then uses Design-Building software and testing procedures before and during construction, ensuring our clients peace of mind that their homes will perform as designed.

  • Can be achieved with any Design Style or Building Budget.
  • There are absolutely no restrictions on size or architectural styles, this is due to the fact that our building standard concentrates on a few key building elements from proven and tested building science technology.

  • Future Proofed – Significantly Lower Carbon Emissions
  • Passive Homes produce significantly less energy than conventional homes, resulting in radically reduced CO2 emissions, making this is the most sustainable building standard in the world (no green wash). You save on energy and improve your life-style whilst reducing carbon emissions. This is the positive change the world needs to reduce global warming.

  • Heathier Home – Less Dust, Pollens & Allergens
  • Due to air tightness, energy recovery ventilation systems, controlled temperatures & humidity plus filtered fresh, you will be living and breathing a perfectly healthy environment, minimising levels of dust, mold and pollens. The health benefits have been documented in several articles from people around the world living in PassivHaus homes; reduced illnesses, better sleeping patterns, less asthma and allergies have all been reported.

  • A Quiet Haven – Highly Reduced Noise Levels
  • By default, the higher quality of external materials insulates the outside noise, making your home noticeably quieter.

  • Unreal Comfort – Set Temperatures & Humidity all year Round.
  • You may have lived and experienced houses overheating in summer and freezing in winter, two level homes with upper level temperatures 15 degrees higher than the bottom level, the list goes on in Australia… Now imagine temperatures 20-25 degrees regardless of outside weather in both summer & winter, using minimal energy consumption.YES, it’s possible with a H4 High Performance Passive Home.

  • Lifetime Energy Savings – Ultra Low Energy Consumption
  • By creating a sealed thermal envelope, minimal heating and cooling is required, therefore dramatically reducing your energy bills comparatively to standard building codes.This reduction in energy has nothing to do with solar panels, solar is considered a bonus! This innovative technology results in much lower monthly energy bills, providing families a lifetime of savings.

  • Indoor Air Quality – Filtered Fresh Air (No Cold or Hot Draughts)
  • The importance of indoor air quality that affects human health can not be underestimated. Concentration of pollutants indoors are 4 to 5 times higher than typical outdoor concentrations, and people now spend 90% more time indoors. With A H4 High Performance PassiveHaus, the risk of pollutants is reduced drastically due to our recovery ventilation systems.

  • Proven Tested Measured – 65,000 PassivHaus Projects Worldwide ✔
  • Would over 65,000 passivehaus TM projects built and tested worldwide be enough to convince you it’s the best building standard in the world? A holistic approach from design to construction is required, there are very clear definitions and requirements set by the PassivHaus institute, and this has continually been proven from concept to completion.

PassivHaus certification’s main benefit is the rigorous quality assurance and performance tests the home is required to meet. From design details, all the way through to airtightness, tests are conducted both during and after construction.
PassivHaus certification is achieved by a third-party verification to keep Designers and Builders accountable. Here at H4 we hope that Australia will make this building standard compulsory.
H4 Living encourages PassivHaus certification, the additional cost is your guarantee that you have the best building standard in the world.
