The passive house institute has developed several building techniques to suit the central European climate. The passive house concept and laws remain the same around the world, however different details may need to be found to suit the climate and geographic conditions. The first step is to use the passive house process which will determine solutions for each region and climate.Passive houses may appear quite different but the principle which is to reduce investment through energy efficient design remains the same. The overall heat demand for the house is reduced by means of insulation, heat recovery, passive solar gains etc. and this means the house will have very low energy demand for maintaining interior comfort in the heating season. The peak heating should be projected to lower level than 10W/m² which will require careful planning in colder climates. In other regions however other energy sevices such as cooling or dehumidification could be more important than heating. It is important in every design that comfort is at a high level for the occupant.
After assessing the goals of the passive house it a computer based parmetric study of the design to check the results for energy demand, financial investment and healthy indoor climate.
