The building sector has become much greener. To get such credentials it has adopted methods borrowed from other industries, such as life cycle analysis (LCA), which looks at the environmental impact of a building at every stage from its creation to its decommissioning. “Taking a global view over the entire life cycle of a building avoids a shift of burden”, Katrin Lenz tells youris.com. She is an expert in LCA at the Fraunhofer Institute for Building Physics in Stuttgart, Germany, and a partner in the DIRECTION project aiming to develop low energy buildings.

Calculation of heating/cooling loads
Thermal loads are calculated in each zone, taking into account the dynamic behaviour (the time step can be chosen between 1/10 and 1 hour) and possible air exchange between zones (up to 20 zones in a building).

Task “Impact and saving potential of North European very low-energy houses in Northern Europe" of the NorthPass project analysed the savings potential and identified the success factors of North European very low-energy houses. The purpose of this report is to present the methodological background of the work and to introduce the methodology of Life Cycle Cost Analysis (LCC), Life Cycle Assessment (LCA) and Cost-Benefit Analysis (CBA).

This project aims to develop documents and instruments providing operational guidance for Life Cycle Assessment studies of the Energy Efficient Buildings Initiative.
LCA is used to assess the environmental benefits of new technologies. The EeBGuide manuals and guidance will support LCA practitioners to obtain comparative results in their work.
This project is supported by the European Commission under the Environment (including climate change) Theme of the 7th Framework Programme for Research and Technological Development.

Aluminium is a very young metal, extracted for the first time in 1854. Commercially produced as a precious metal from 1886, its industrial production for civil applications only took off in the 1950’s. The first well-known application in buildings dates back to 1898, when the dome of San Gioacchino’s Church in Rome was clad in aluminium sheets. The stunning Art Deco-inspired Empire State Building in New York was the first building to use anodised aluminium components back in 1931.

I would like to start a discussion about the application of life cycle assessment (LCA) and life cycle thinking (LCT) in the design and refurbishing of buildings.
LCA allows considering the impact in all the stages of their life cycle, including the production of the building materials and equipment, the transportation and construction, the use and maintenance, and the final disposal. Therefore the life cycle approach allows to avoid trade-offs between stages of the life cycle of products, impact categories or geographical areas.
