Key principles of passive house design
Passive solar design is a fundamental aspect of passive house standards. This approach involves strategically positioning your home to maximise solar gain during winter and minimise it during summer, significantly reducing energy consumption.
Passive solar heating is a key component of this design, utilising natural sunlight to warm your home efficiently.
Passive house standards also emphasise airtight construction and high-performance insulation, ensuring that heat generated inside the home stays put.
These principles result in consistent and comfortable indoor environments with minimal reliance on external heating sources. Our passive design expertise allows us to create energy efficient homes in Brisbane, the Gold Coast, and throughout Australia.

Our expertise in passive home construction ensures that you can enjoy the following advantages:
Energy savings and lower utility bills
One of the primary advantages of passive homes in Australia is their exceptional energy efficiency. By incorporating passive solar design and high-performance insulation, these homes significantly reduce the need for artificial heating and cooling. This results in substantial energy savings and lower utility bills, making passive homes a smart financial investment over time.
Improved indoor air quality
Passive homes are designed with airtight construction and heat recovery ventilation systems, which contribute to superior indoor air quality. These systems continuously bring in fresh air while removing stale air, ensuring that your home remains healthy and comfortable.
Increased comfort and consistent temperatures
The consistent temperatures maintained in passive homes enhance overall comfort. Unlike traditional homes that may experience significant temperature swings, passive homes provide a stable and pleasant living environment throughout the year.
Reduced environmental impact
By minimising energy consumption, passive homes have a lower carbon footprint compared to conventional houses. This reduction in energy use not only benefits the environment but also aligns with the growing trend of sustainable living.
Essential features of a passive home
At IDNA Homes, we incorporate several essential features in our passive house designs to achieve optimal energy efficiency and comfort for our clients. These key elements work together to create a truly sustainable living environment.
High-performance insulation
High-performance insulation is a cornerstone of passive solar house design. It helps to keep the heat inside during the winter and outside during the summer, contributing to the home’s overall energy efficiency. Proper insulation also reduces noise, enhancing the comfort of your living space.
Airtight construction
Airtight construction ensures that your home is sealed against air leaks, preventing drafts and heat loss. This feature is crucial for maintaining the efficiency of the home’s heating and cooling systems.
Energy-efficient windows and doors
Windows and doors in passive homes are specially designed to minimise heat loss and gain. Triple-glazed windows and well-insulated doors are common features that help to maintain a consistent indoor temperature.
Heat recovery ventilation systems
Heat recovery ventilation systems are essential for ensuring that fresh air is continuously introduced while recovering heat from the outgoing stale air. This system enhances indoor air quality while reducing the need for additional heating.

Passive home design for Queensland's climate
Designing a passive home for Queensland’s hot and humid climate requires specific adaptations of passive house principles.
At IDNA Homes, we’ve developed expertise in creating comfortable, energy-efficient homes tailored to Queensland’s unique conditions. While we started as Sunshine Coast and Brisbane builders, our experience now extends nationwide, allowing us to adapt passive house principles to various Australian climates. Queensland’s climate presents unique challenges for passive solar design.
While the principles of passive house design remain the same, they must be adapted to manage the region’s heat and humidity effectively. This includes optimising shading to reduce solar gain and incorporating natural ventilation strategies to cool the home.
Strategies for natural cooling in Queensland homes
Our passive home designs for Queensland incorporate several key strategies to ensure year-round comfort. To address the hot climate, passive homes in Queensland often feature design elements that enhance natural cooling.
This includes cross-ventilation techniques, where strategically placed windows and vents allow cooler breezes to flow through the home. Additionally, overhangs and shading devices are used to protect windows from direct sunlight.
Managing solar gain is crucial in Queensland’s climate. Passive solar house design incorporates features such as adjustable shading systems and reflective window coatings to balance the amount of solar energy entering the home.
This ensures that the home remains cool during the hot months while still benefiting from passive solar heating in cooler periods.
The cost of building a passive home
Building a passive home often involves a higher initial investment compared to traditional homes. This is due to the need for specialised materials and advanced construction techniques.
At IDNA Homes, we understand this investment and work with our clients to create cost-effective solutions that meet their needs and budget. In Australia, there are various government incentives and rebates available for building energy-efficient homes.
These incentives can help to reduce the initial costs of constructing a passive home, making it a more accessible option for many homeowners.
Our team stays up-to-date with these incentives and can guide you through the process of accessing them.
