FAQ

A high-performance home is designed to maximise energy efficiency, comfort and health. Zelena Homes uses airtight construction, continuous insulation, high-performance windows and HRV systems to create a home that maintains consistent indoor temperatures, improves air quality and reduces energy consumption. 

Airtight construction minimises drafts, reduces energy loss and improves indoor air quality. It ensures your home remains comfortable by controlling temperature and preventing external pollutants from entering. 

Continuous insulation provides a consistent thermal barrier throughout your home, preventing energy loss through walls, floors, and ceilings. This feature eliminates thermal bridging, which improves energy efficiency and reduces heating and cooling costs. 

High-performance windows and doors are specially designed to prevent heat loss and maintain a comfortable indoor environment. They reduce energy consumption, block drafts, and enhance noise reduction while improving the overall comfort of your home. 

Passive solar design uses your home’s orientation and window placement to naturally heat and cool your space. This reduces the need for artificial heating and cooling systems, saving energy and lowering utility bills while making the home more sustainable.

An HRV system improves indoor air quality by exchanging stale indoor air with fresh outdoor air while recovering heat from the outgoing air. This helps maintain a healthy, well-ventilated home without wasting energy. 

While high-performance homes may have slightly higher upfront costs due to advanced materials and systems, they save money over time through reduced energy bills, lower maintenance costs and government rebates on energy-efficient features like solar panels and heat pumps.

High-performance homes save on energy bills by reducing heating, cooling, and electricity needs. Over the life of the home, these savings can significantly offset the initial building costs. You’ll also benefit from reduced maintenance due to durable construction and energy-efficient technologies. 

Both high-performance homes and passive houses focus on energy efficiency. However, high-performance homes offer flexibility in design and technology while incorporating passive design principles. Passive houses follow strict standards for energy use and often aim for zero-energy buildings. 

Zelena Homes uses advanced HRV systems and airtight construction to filter out pollutants and maintain fresh air circulation, creating a healthy indoor environment. The design also prevents mould and moisture build-up, ensuring clean air quality for years to come. 

Yes, Zelena Homes allows for customisation based on your specific needs and preferences. From selecting finishes to incorporating unique energy-efficient features, your home can be tailored to fit your lifestyle. 

The timeline depends on the complexity of the project. On average, a high-performance home by Zelena Homes takes 14 to 18 months to complete, from design to move-in. The process includes initial consultations, design planning, construction, and thorough testing of all systems. 

Yes, several government incentives and rebates are available for energy-efficient homes. These include rebates for solar panels, energy-efficient appliances, and heat pumps. Zelena Homes can guide you on how to take advantage of these programs.

Passive solar design uses natural sunlight to heat your home during winter and block excess heat in the summer. This reduces the need for artificial heating and cooling, significantly cutting energy costs over time. 

Zelena Homes uses high-quality, energy-efficient materials such as continuous insulation, vapour-permeable membranes, and water barriers. These materials improve thermal performance, enhance durability, and prevent moisture-related issues like mould. 

By using less energy for heating, cooling, and electricity, high-performance homes significantly lower carbon emissions. They are designed to integrate with renewable energy sources like solar power, further reducing their environmental footprint.
