High performance Building
Passive House & High-Performance Building Solutions.
At BBG Built, we’re passionate about high-performance building — creating smarter, more efficient, and healthier homes for New Zealanders. Our approach is grounded in proven building science and modelled design, tailored to your specific project and climate.
We help homeowners, developers, and investors build homes that deliver superior comfort, exceptional energy efficiency, and long-term value. Whether you’re planning a compact family home, a secondary dwelling, or a sustainable investment property, a high-performance build offers a better way to live in Aotearoa.
What Is a Passive House?
A Passive House is designed and constructed to maintain consistent indoor comfort throughout the year — requiring minimal energy for heating or cooling. These homes are built to exacting standards, achieving exceptional thermal performance and airtightness through intelligent design and verified modelling.
To achieve full Passive House certification, a building must meet a set of performance criteria covering heating demand, airtightness, and overall energy use.
But certification isn’t the only path to building better.
What Is a Passive House?
Not every project needs to meet full Passive House standards to achieve significant gains in comfort and efficiency. Many of the same design principles can be applied to traditional timber-framed homes or renovation projects to dramatically improve performance.
We can incorporate:
Thermal bridge-free design
Improved airtightness
Mechanical ventilation with heat recovery (MVHR)
High-performance insulation suited to your climate zone
At BBG Built, we work with you to find the right balance — guiding your design and construction choices so you gain the benefits of modern building science, even if full certification isn’t your goal.
Benefits of SIP Passive House Construction
We collaborate with trusted Structural Insulated Panel (SIP) providers to deliver efficient, durable, and energy-smart homes. SIP construction provides a precision-engineered building envelope with outstanding performance across every key area:
-
Rapid and efficient on-site assembly
-
Superior thermal insulation and airtightness
-
Built-in compatibility with MVHR systems
-
Thermal bridge-free detailing for consistent comfort
-
High-performance windows for reduced noise and heat loss
-
Lower energy costs and carbon emissions over the home’s lifetime
Why Build Above the Code?
New Zealand’s building code sets a minimum standard, not a benchmark for comfort or efficiency. As energy costs rise and expectations shift toward warmer, healthier homes, choosing to build above code delivers tangible benefits:
-
Cleaner, healthier indoor air through filtered ventilation
-
Lower power bills with reduced heating and cooling demand
-
Consistent comfort in every room, year-round
-
Long-term durability through high-quality materials and detailing
-
Reduced environmental impact through energy-efficient design.
Built for New Zealand Conditions
In the South Island — where winters are long and cold — building with performance in mind from day one makes all the difference. By applying proven Passive House principles, we’re setting a new standard of living comfort for Kiwi families.
