Passive house can be built in different climate zones!

Quoting of work “Passive Houses for Different Climate Zones” by J.Schnieders where the studies demonstrate that passive house is technically feasible in all these locations (Yekaterinburg, Tokyo, Shanghai, Las Vegas, Dubai, Singapore, Salvador, and Mumbai).

The hot regions (with max outdoor average temperature 40°C the components available on the market still managed to suffice) are not problem, but the very cold areas are. In daily average temperatures of -70°Cwith negligible insulation, the external components – windows – would have to be customized and it does not currently pay off. In theory it is interesting but not practical as these regions have very scarce population.

The tropics with slight seasonal temperature fluctuations has no need for heating in these periods but annual cooling demand can be great even if cooling loads are small. The economic analysis shows that building standards that go beyond the functional passive house level are the best economic solution for these climate zones. Hygrothermal calculations show that different construction component combinations will have to be used depending on the location. Designs that have proven useful in a certain climate may be completely unsuitable elsewhere.

Schnieders stated: “In any case, the Passive House concept will have to be adapted to local building traditions, climates, and aesthetics.”

“It was also found that, apart from the prototype inexpensive row houses, architecturally demanding buildings can also be realized in the Passive House Standard, albeit with more expenditure being required in some cases than with simple buildings with moderately glazed façades. Architectural freedom and design leeway is provided by the Passive House principle, even within building cultures that developed over centuries.”
