Insight on Life Cycle Assessment!
As Total Lifecycle Energy Environmental Assessment is one out of the six key strategic areas, where progress beyond state of the art will be demonstrated within PERFORMER, it is relevant to make an insight into the most recent achievements in this field. PERFORMER targets, among others, a full assessment on environmental, social as well as economic influences of construction projects. One of the most important PERFORMER’s aims is to critically review financial payback analyses and LCA methods with a focus on energy and to develop a complex and appropriate method for the energy retrofitting sector.
State of the art in LCA is reflected in work performed within the EU FP7 funded EeBGuide project (http://www.eebguide.eu/), which outcomes are training materials, policy notes and guidance for the preparation of LCA studies for energy efficient buildings and building products. The EeBGuide manuals were developed to support LCA practitioners in obtaining comparative results in their work. The outcomes of the guidance document may also serve as a basis for building LCA tool developers or certification schemes as they provide information on how to deal with specific issues such as how to account for technical building equipment or how to take account of service life.
Considering environmental and economic assessment in the construction sector and taking it into account PERFORMER’s goals in this field, it is worthy to put some attention to the CILECCTA – recently completed (August 2013) large-scale project co-financed by the EU under the FP7. The innovative part of CILECCTA project is the use of integrated methodology that ensures the compatibility between LCC and LCA. CILECCTA connects environmental Life Cycle Assessment (LCA) and monetary Life Cycle Costing (LCC) in one combined LCC+A approach. This joint methodology allows LCC and LCA to be carried out in parallel within the CILECCTA outcome – software tool. In this way, the problem of conducting two separated analyses and problems of inconsistency between the two methods have been overcome. The idea was to make the software compatible with a variety of European price banks and life cycle inventories in order to provide decision makers with trustworthy decision support tool. According to the description provided by the CILECCTA consortium, the mentioned software is a user-friendly interface that easily enables users to analyse economic considerations and environmental impacts of a construction project throughout its life cycle. CILECCTA consortium is going to make the software available commercially, in the meantime CILECCTA learning module about LCC, LCA and LCC+A together with other project materials is offered at the Cileccta website: http://www.cileccta.eu/. More information on CILECCTA software and combined LCC+A methodology might be downloaded from e-handbook.
