The projects are very different in size and type, ranging from single family residential buildings (Skarpnes, ZEB House Multikomfort, Zero Village Bergen, and ZEB Living Lab) to office buildings (Powerhouse Kjørbo, Powerhouse Brattørkaia, and Visund) and educational buildings (Heimdal VGS and Campus Evenstad). They are located in different climates and contexts, from the relatively temperate and moist coastal climate of Bergen in the west of Norway, via the more sunny climate of Larvik in the east, to the cold inland climate of Evenstad. The northernmost location is Trondheim. However, this climate is milder than the inland climate of Evenstad. Powerhouse Kjørbo, Powerhouse Brattørkaia, and Heimdal VGS are situated in urban/suburban environments, while the remainder of the projects have more suburban/rural locations. In the following, some of the main characteristics and lessons learned from the pilot building projects are summarized, focusing on the design and construction processes, the design choices, and the experiences from the operation and use of the buildings.
The design and construction processes In all of the ZEB pilot building projects, an integrated energy design process has been used, as explained in chapter 2.2. This involves a process of establishing clear goals for the environmental performance, employing multi-disciplinary cooperation from day one, and using advanced tools for performance documentation throughout the process.
