In fact, the better you insulate your building, the more you need to pay attention to rat-runs to get the full benefit of the thermal separation. The following instructions are a refresher for people who did thermal bridge Read more about How to account for thermal bridges[…]
The right tools are needed to do a proper energy modelling job. For Certified Passive Houses, using the Passive House Planning Package (PHPP) is mandatory. It is the only energy modelling tool in the world that has successfully been tested against real-world results on a large number of projects (see here for some examples).

Despite the myth, there is no indication that Kiwis are more tolerant to colder temperatures than people elsewhere in the world, which should not come as a surprise, as many of us were born overseas, or grew up in far away places. In fact, several NZ studies suggest that if Kiwis are capable, technically and financially, to heat their homes to the degree Americans and Europeans are accustomed to, they will (Fyfe, 2005; Howden-Chapman et al, 2009).
