The policy of the Dutch national government currently directs that new homes be zero energy (nearly) by 2020. This is referred to as nearly Zero Energy Buildings (nZEB) or ‘Bijna Energie Neutrale Gebouwen’ (BENG). The energy performance coefficient (EPC) for housing under this policy is tightened to 0.4. Meanwhile, the EPC requirement for commercial buildings is tightened 50% as compared to 2007 levels. As a result, higher demands are being placed on the thermal envelope of a building. Besides the development of insulating materials such as vacuum panels and aerogels that improve EPC performance while still maintaining a thin wall and roof profile, there is also enormous interest in the use of sustainable materials to achieve better thermal performance. This includes biobased insulation materials such as wool, seaweed, shells, cellulose and biofoams. For every application there is a solution!
