FAQs for Sustainable Homes
Building or renovating with sustainability in mind means balancing comfort, efficiency, and long-term value. Here are some common questions and expert answers to help you get started.
-
A Passive Home is designed to be energy efficient, comfortable, and healthy. Regular homes often lose heat through gaps, poor insulation, and inefficient windows, relying heavily on heating or cooling.
Passivhaus (the formal international standard) sets a much higher benchmark. It delivers comfort through airtightness and insulation, health through constant fresh, filtered air, and low bills because very little heating or cooling is required. Every certified Passivhaus is independently tested to ensure it performs as designed.
-
BASIX: Mandatory in NSW. A compliance tool to meet minimum government sustainability targets.
NatHERS: A national star rating system (0–10) that predicts thermal comfort and energy efficiency at design stage.
Passivhaus: A voluntary international standard focused on health, comfort, and verified performance, with independent testing.In short: BASIX = minimum compliance, NatHERS = predicted efficiency, Passivhaus = proven comfort and performance.
-
BASIX is mandatory in NSW. To meet its thermal comfort requirements, a 7-star NatHERS rating (or equivalent) is generally used as the benchmark. Passivhaus, on the other hand, is voluntary.
While BASIX and NatHERS ensure minimum compliance, Passivhaus is considered the “gold standard.” It goes well beyond compliance by delivering verified comfort, health, and ultra-low energy use through independent testing and certification. If your goal is more than just meeting the rules, Passivhaus represents the highest level of performance.
-
Passivhaus works in every climate. In Sydney, it means homes stay cool in summer, warm in winter, and healthy year-round. You can still open your windows, but when closed, the ventilation system filters pollution, allergens, and even bushfire smoke while recovering warmth or coolth.
-
The Property Inspection + Sustainability Service is best for buyers or current owners who want a clear picture of how a home is performing now. It includes an on-site inspection, issue identification (leaks, mould, inefficiencies), and a 10–12 page report with tailored recommendations.
The Design & Sustainability Consultation + Report + Sketches is ideal for property owners at the start of a new build or major renovation. Alongside planning advice and budget guidance, you receive a feasibility report, sustainability assessment, and two hand-drawn sketch options tested against performance criteria.
-
A Property Inspection usually takes an hour on site, with the report delivered within about 10 working days. A Design & Sustainability Consultation involves more detailed analysis and sketches, so we also allow up to 10 working days to prepare the full report and drawings.
-
The Property Inspection report is 10–12 pages with findings, photo markups, and recommendations on energy, water, thermal performance, and property condition.
The Design & Sustainability Consultation report includes a Development Feasibility Report with planning details, sustainability performance summary, tailored recommendations, and two sketch options reviewed by a certified sustainability consultant. -
The best starting point is early planning. Engage a sustainability consultant at concept stage, alongside your architect or builder. This ensures sustainability strategies are integrated from day one rather than added later as “fixes.” For renovations, a sustainability consultation can help identify the most cost-effective improvements.
At Ballast Point, we offer two tailored services to help you start: Design & Sustainability Consultation + Report + Sketches and Property Inspection + Sustainability Service. Both combine architectural expertise with certified Sustainability advice, giving you a clear roadmap to a healthier, more efficient home. -
The best way is with expert guidance at the start of your project. At Ballast Point, we bring together our architect, builder, and a certified Passivhaus consultant to give you practical solutions, clear budgets, and a pathway toward a healthier, more comfortable, and energy-efficient home.
