15 Gree en Bu uilding Pa ay? 2011 Extract from Siemens citation: Henning Larsen s winning design was selected for its comprehensive approach to sustainability an approach that meets the highest standards for ecofriendliness and energy efficiency.

17 Gree en Bu uilding Pa ay? 2011 CEO Peter Löscher, Siemens, says in a press release: We re creating a futureoriented symbol of sustainability that will set the standard for advanced urban architecture and innovative, efficient building technology for the benefit of our employees and the citizens of Munich.

Bæredygtighedslog Bygherrens målsætning Niveau Plan (P), bygning (B), bygningskomponent (BK), materiale (M) 1 Klima / CO2 minimering af klimapåvirkninger Mål Niveau Skala Design og arkitektur Livs cyklus Økonomi Ansvar Tidspunkt CO2 rigtigt byggeri er det samme som energirigtigt byggeri hvis energien kommer fra de samme kilder! Hvis man skifter til en mere klimavenlig energikilde, begrænser man C02 udslippet. El, kul, koks og olie giver størst udslip. Naturgas, fjernvarme og varmepunper er bedre. Halm, tre, sol og vind er C02 neutrale kilder. Hvad der præcist er godt for klimaet, kommer an på de lokale forhold. At opvarme et dårligt isoleret hus med halm eller træ er ikke godt for klimaet, hvis biomassen kan anvendes på en anden måde, der fortrænger mere C02, f.eks. Kraftvarme eller ethanol. Der er forskellige typer virkemidler til substitution af forbruget af fossile brændsler. Hver dansker udleder 10 ton CO2 pr. indbygger om året. I denne masterplan er det intentionen at brugernes CO2 skal være max 6 ton C02, knyttet til områdets drift, og min 50% af energiforsyningen skal komme fra vedvarende energikilder P ALPHA BETA GAMMA X DELTA P/B Beslutnings og realiseringsniveau Vurderingsmetode Dokumentation Strategi / Virkemiddel og værdi Effekt Fokus Anlæg Drift Aktør Fase Prioriteres Mål opnås Analyse / vurdering / beregning / metode Notat, referat, tegninger, beskrivelser, mm.
