Wat betekent duurzaam werken onder verschillende klimatologische en geografische omstandigheden? Hoe bespaar je energie met het verduurzamen van gebouwen in verschillende landen in Europa. Dat zijn de 2 kernvragen van het internationale project Old Buildings, New Technology waar de opleiding bouw van ROC Friese Poort aan deelneemt. Dinsdag 6 oktober 2015 kwamen alle 8 partnerlanden met docenten en studenten bij elkaar op de locatie van Centrum Duurzaam in Leeuwarden. Studenten uit Nederland, Noorwegen, Polen, Hongarije, Slowakije, Griekenland en Turkije presenteerden hun duurzame invalshoek op het verduurzamen van gebouwen.

What Why
Scullery demolition To make space for the
conservatory.
New window frames Most of the window frames are
rotten.
New Fascias (roof boards) Fascias on the south side are
rotten.
New Joints The joints on the west side are
falling out.
New sun room To create more living space.
New carport Mr. Roest can keep his car dry.
New window sills Some of the window sills are
loose.
Painting dormer So the wood doesn’t rot.

18. Conclusion
 RC-values of the floor, roof and the exterior wall don’t all
meet the recent requirements, so we improved it:
 The roof went from 2,225 to 5,942
 The ground floor went from 0,159 to 3,904
 The exterior wall went from 0,5 to 4,519.
