Contain the house in an excellent thermal insulation with no thermal bridges
| U~≤~0,15~W/m2K
|
Employ the best triple glazing and adequate
frames (integrated to the surrounding insulation layer)
| U~≤~0,8~W/m2K
|
Ensure an excellent air-tightness of the house, repeatedly checked
| n50~≤~0,6~h-1
|
Use a mechanic ventilation, recovering vast amount of heat,
| ≥~0,8
|
with excellent ratio heat / fan electricity
| ≥~10
|
Using the most energy-efficient technologies for all other appliances

The above technology demands hold for any house which is to be
comfortable during hot periods. Just in winter the last item could be
skipped. It might seem that even the preceding item has nothing to do
with comfort, but: low electricity consumption can be achieved just by
low velocities of airflow in the system, and low velocities reduce the
noise level. It is possible to achieve low noise level, when nobody is
inclined to switch the ventilation off to get rid of noise, even through
dampers, but their inclusion increases power demands further. And
finally, just a house obeying the first three rules is really durable,
not degrading due to moisture condensing in its construction.
