(ar) Šedá energie či ztělesněná energie je označení pro energii potřebnou na výrobu, dopravu, uložení, prodej a likvidaci. Je důležitou součástí životního cyklu produktů napříč různými obory a průmysly – ať už jde o dopravu, stavebnictví, design nebo potravinářství. (cs) Die graue Energie eines Produktes ist die benötigte Energie für Herstellung, Transport, Lagerung, Verkauf und Entsorgung. Berücksichtigt werden auch alle Vorprodukte bis zur Rohstoffgewinnung, als auch der Energieeinsatz aller angewandten Produktionsprozesse. Wenn zur Herstellung Maschinen oder Infrastruktur-Einrichtungen notwendig sind, wird üblicherweise auch der anteilige Energiebedarf für deren Herstellung und Instandhaltung in die „graue Energie“ des Endprodukts einbezogen. Das „Produkt“ kann auch eine Dienstleistung sein. Graue Energie ist somit der indirekte Energiebedarf durch Kauf eines Konsumgutes, im Gegensatz zum direkten Energiebedarf bei dessen Benutzung. Der kumulierte Energieaufwand (KEA) fasst diese Teilbereiche zusammen. (de) Embodied energy is the sum of all the energy required to produce any goods or services, considered as if that energy was incorporated or 'embodied' in the product itself. The concept can be useful in determining the effectiveness of energy-producing or energy saving devices, or the "real" replacement cost of a building, and, because energy-inputs usually entail greenhouse gas emissions, in deciding whether a product contributes to or mitigates global warming. One fundamental purpose for measuring this quantity is to compare the amount of energy produced or saved by the product in question to the amount of energy consumed in producing it. Embodied energy is an accounting method which aims to find the sum total of the energy necessary for an entire product lifecycle. Determining what constitutes this lifecycle includes assessing the relevance and extent of energy into raw material extraction, transport, manufacture, assembly, installation, disassembly, deconstruction and/or decomposition as well as human and secondary resources. (en) L’énergie grise, ou énergie intrinsèque, est la quantité d'énergie consommée lors du cycle de vie d'un matériau ou d'un produit : la production, l'extraction, la transformation, la fabrication, le transport, la mise en œuvre, l'entretien et enfin le recyclage, à l'exception notable de l'utilisation. L'énergie grise est en effet une énergie cachée, indirecte, au contraire de l'énergie liée à l'utilisation, que le consommateur connaît, ou peut connaître aisément. Chacune des étapes mentionnées nécessite de l'énergie, qu'elle soit humaine, animale, électrique, thermique ou autre. En cumulant l'ensemble des énergies consommées sur l'ensemble du cycle de vie, on peut prendre la mesure du besoin énergétique d'un bien. L'affichage de l'énergie grise peut guider ou renseigner les choix d'achats, notamment en vue de réduire l'impact environnemental. (fr) 체화 에너지(embodied energy)란 천연 자원 채취로부터 제품 배송에 이르는 건물 건축과 관련된 전 과정에서 소비되는 에너지를 말한다. 이것은 자재 및 장비의 체굴과 생산, 자재의 운송과 행정적 기능들을 포함한다. 건축분야에서는 내재에너지라고 한다. 모든 건물은 가공 자재의 복합체이며 사용된 가공 자재에 따라 각 빌딩의 총 체화 에너지가 결정된다. 유지와 보수는 또한 건물 생애 기간 동안의 체화 에너지를 증가시킨다. 최근까지는 건물 생애 기간 동안 건물을 운영하는 데 사용되는 에너지에 비해 체화 에너지의 크기가 적다고 여겨져 왔다. 따라서 외장재 에너지 효율을 증대하여 건물 운영에너지를 줄이는 데 많은 노력이 집중되어 왔다. 조사에 따르면 항상 그러한 것(체화 에너지<운영 에너지)은 아니라는 것이 밝혀졌다. 체화 에너지는 한 건물의 100년 생애 기간 중 20년 간의 운영 에너지와 크기가 같을 수 있다. 체화 에너지를 줄이기 위해서는 튼튼하고 개조가 가능하며 수명이 길도록 건물을 디자인하는 것이 가장 중요하다. (ko) L'energia grigia è la quantità di energia necessaria per produrre, trasportare fino al luogo di utilizzo, e smaltire un prodotto o un materiale o per assicurare un servizio. L'energia grigia può essere anche chiamata "energia virtuale", "energia congelata" o "energia nascosta". Generalmente, con il termine energia grigia si indica una metodologia per valutare l'ammontare totale dell'energia utilizzata nel corso dell'intera vita del prodotto: estrazione delle materie prime, trasporto, trasformazione, montaggio, installazione, come pure la demolizione e lo smaltimento. Alcune metodologie puntano a esprimere l'energia grigia in termini di consumo di petrolio necessario; altre metodologie valutano l'energia grigia in termini di quantità di luce solare che viene utilizzata nei processi ecologici. Il inglese e il LEED Leadership in Energy and Environmental Design americano sono gli standard secondo i quali viene valutata, insieme ad altri fattori, l'energia grigia di un prodotto o di un materiale, per misurare l'impatto ambientale di una costruzione. L'energia grigia è un concetto nuovo, sul quale gli scienziati non hanno ancora raggiunto un accordo generale riguardo ai valori calcolati poiché ci sono molte variabili da considerare, ma la maggior parte concordano sul fatto che i prodotti possono essere confrontati fra di loro per decidere quali abbiano una quantità maggiore o minore di energia grigia. Tabelle comparative (ad esempio, vedi la Bath University Embodied Energy & Carbon Material Inventory in bibliografia) riportano valori medi assoluti, e spiegano quali sono i fattori che sono stati presi in considerazione nel compilarla. Le unità di misura tipicamente usate sono il MJ/kg (megajoule di energia necessaria a ottenere un chilogrammo di prodotto) e il tCO2 (tonnellante di anidride carbonica liberata dall'energia necessaria a produtte un chilogrammo di prodotto). La conversione da MJ a tCO2 non è automatica, poiché i differenti tipi di energia (da petrolio, eolica, solare, nucleare e così via) producono quantità differenti di anidride carbonica, per cui la quantità effettiva di anidride carbonica liberata durante la produzione di un oggetto dipende dal tipo di energia utilizzata nel processo produttivo. Tuttavia, il sito di ricerca del Governo australiano (vedi il link al CSIRO sotto) fornisce una media di 0.098tCO2 = 1GJ, che equivale a 1MJ = 0.098kgCO2 = 98gCO2 o 1kgCO2 = 10.204MJ. (it) |
