Energi analyser i Project VASARI

Jeg håber I er begyndt at kigge lidt på Project Vasari. Der ligger en masse muligheder for at analysere på design af bygninger, lave alternativer osv. Selve analysedelen kan være lidt svær at gennemskue. Selve valget af konstruktion foregår med nogle predefinerede typer, disse har nogle egenskaber som udelukkende er defineret med amerikanske værdier for varmetab. De bruger en R-Value som IKKE svarer til europæisk R-Værdi. Dermed kan vi ikke direkte udregne U-Værdien som den reciprokke (1/x) af R-Værdien. For at komme fra amerikansk R-Value til europæisk R-Værdi skal der ganges med 5,682.

I skemaet nedenfor kan U-værdien aflæses for de konstruktionstyper der kan vælges i Project Vasari.
