Gericht op CO\u2082-reductie<\/strong><\/p>\n

Onze duurzaamheidskeuzes worden mede bepaald door budgetten en planning. Daarom sturen we actief aan op het verlagen van onze CO\u2082-footprint. Operationeel een logistiek gebouw CO\u2082 neutraal maken is relatief eenvoudig: gasloos bouwen en circa 25% van het dakoppervlak voorzien van PV-panelen brengt ons al ver. De echte uitdaging ligt echter in de materiaal gebonden CO\u2082-emissies tijdens de bouw. Deze embedded footprint is vaak vele malen groter dan de operationele CO\u2082-uitstoot van het gebouw, bijvoorbeeld voor verlichting, verwarming en koeling.<\/p>\n

Data-gedreven inzichten<\/strong><\/p>\n

Bij Delta berekenen we al jaren de totale CO\u2082-footprint, inclusief materialen, operationele uitstoot en energieopwekking. Dit doen we samen met WiseBrick, waarmee we gedetailleerde inzichten verkrijgen. Ons eerste project met een uitgebreide CO\u2082-inventarisatie was HelloWorld in Hoofddorp, ontwikkeld met VolkerWessels Logistics Development op Schiphol Trade Park.<\/p>\n

Confronterende resultaten <\/strong><\/p>\n

De resultaten waren een wake-up call. Dit Cradle-to-Cradle\u00a9 geoptimaliseerde, BREEAM Excellent gebouw met energielabel A+++++ en een MPG-score van 0,31 had een materiaalgebonden CO\u2082-uitstoot van ruim 18 miljoen kg CO\u2082. Dit komt neer op 381 kg CO\u2082 per m\u00b2. Ter vergelijking: deze footprint was 80 keer groter dan de jaarlijkse operationele uitstoot! Verder heeft dit cijfer (i.v.m. Paris Proof standaard) alleen betrekking op de productie- en bouwfase van het hoofdgebouw \u2013 de werkelijke impact over de volledige levenscyclus ligt dus n\u00f3g hoger.<\/p>\n

De Dutch Green Building Council stelt de grenswaarde voor materiaal gebonden emissies voor logistieke gebouwen op 240 kg CO\u2082 per m\u00b2 om als \"Paris Proof\" te worden beschouwd. We zaten daar dus nog ver vanaf en zagen ruimte voor verbetering.<\/p>\n

Concrete verbeteringen en Paris Proof certificering<\/strong><\/p>\n

Dankzij de gedetailleerde analyse van WiseBrick kunnen we gerichte keuzes maken en in gesprek gaan met fabrikanten en leveranciers. Meten = weten. Dit resulteerde in ons project ABC Harnaschpolder, wederom samen met VolkerWessels Logistics Development, waar de materiaalgebonden emissies zijn teruggebracht tot 221 kg\/m\u00b2. Hiermee zijn we officieel \"Paris Proof\".<\/p>\n

Blijven innoveren<\/strong><\/p>\n

Kan het nog beter? Absoluut! We blijven zoeken naar innovatieve oplossingen en maken steeds slimmere keuzes binnen onze economische kaders. Stap voor stap, Delta blijft bouwen aan een
duurzame toekomst.<\/p>\n

Future Forward! We maken het verschil!<\/strong><\/p>\n
