Passive House is one of the world's leading standards for high-performance buildings, focused on creating buildings that use very little energy while providing exceptional thermal comfort, indoor air quality and long-term durability.
Based in Wānaka, Performance Building Consultants provides Passive House consulting services across Wānaka, Queenstown, the Southern Lakes and Otago, as well as working with clients throughout New Zealand.
Designing for high performance
Passive House design takes a whole-building approach to energy efficiency and comfort. Careful consideration of insulation, high-performance glazing, airtightness, ventilation, solar gains and thermal bridges allows buildings to maintain comfortable indoor temperatures while significantly reducing heating and cooling demand.
These principles are particularly effective in climates such as Wānaka and Queenstown, where cold winters, significant solar gains and large temperature variations can make achieving consistent indoor comfort challenging.
Passive House design is not simply about adding more insulation or installing better windows. It is about understanding how the building works as a whole and using performance modelling to make informed design decisions.
Passive House certification and high-performance design
I can support projects pursuing Passive House certification, as well as projects that simply want to apply Passive House principles to achieve a higher level of building performance.
For projects where full Passive House certification is not the goal, the Low Energy Building (LEB) pathway can provide a practical way to achieve significantly improved energy efficiency and comfort using the same underlying building science principles.
For renovations and upgrades to existing buildings, EnerPHit provides a recognised Passive House standard specifically developed for high-performance retrofit projects.
What does Passive House consulting involve?
Passive House consulting can include:
- PHPP energy modelling and performance optimisation
- Building envelope and insulation reviews
- Window and glazing optimisation
- Airtightness strategy and blower door testing coordination
- Thermal bridge analysis
- Ventilation and heating strategy
- Solar shading and overheating analysis
- Construction detailing and design reviews
- Support through the Passive House certification process
Early involvement is particularly valuable. By testing design decisions before construction, project teams can identify potential problems early, avoid costly changes later and understand where additional investment will have the greatest impact.
The goal is not simply to meet a performance target, but to create a building that is comfortable, efficient, durable and enjoyable to live or work in.
