Home construction has turned into the art of isolation. Saving energy is easiest in a well isolated home. Besides the roof the walls, doors and windows are next issue. Isolation inside and/or isolation outside are good points of departure. Heat pumps are the next step that needs attention. This is already a sequence of works that have to be planned well in advance. Electric current or LAN wiring or even fibre are additional features a modern home should be equipped with. Lots of different skills involved that we are unlikely to find in traditional occupations. Networks of enterprises are involved in building technologies. Startups in this area could offer better integrated services to clients to advance energy savings rather than the traditional skill sets spread over multiple trades and occupations. Learning tasks and skill needs are abundant.
