Who does what? When are ac1vi1es performed? What couplings exist between individuals and appliances? What does the logical sequence of ac1vi1es look like? What does the structure of ac1vi1es look like in a par1cular household? •  What appliances (and other resources) are used in different projects? •  A detailed view of household energy use •  The uniqueness of every household •

What can energy orders tell housing companies? •  Low energy housing does not become low energy by itself •  There are no average households, energy use will be formed according to individual needs and restric1ons •  Changing household ac1vi1es should start at the household level, only the households will know what will func1on in their everyday life •  Material sefngs should be flexible enough to allow for different ways of doing •  Gather household experiences on energy use in every contact with the households, find out what works and for whom (appliances, storage, space, infrastructure etc.) Thank you!
