This study examines methods of environmental impact assessment during planning of construction projects, with particular focusing on the LCA (Life Cycle Assessment) method.
The essential goal of this work is to provide some insight into the definition of parameters that are most relevant to this assessment. Additional goal is examination of the assessment process that is used in available leading tools: ATHENA, LISA, BEAT, BEES, LEED, and SIMA PRO, and evaluation of these tools based on a real test case.
Analysis of the tools and literature led to emergence of four themes that combine the characteristic criteria of environmental assessment:
· The boundaries and the life-cycle phases of the system to be assessed: the environmental phenomena to be assessed; interaction of the building with its neighboring environment; localization of the assessment tool - data bases.
· General designation: Holistic approach to the construction project; regard for the relationship between building materials and building elements; adaptability to preliminary programming of the project; initial planning; detailed planning; adaptation to procedures in the construction business; presentation of goals, intentions and directives for environmental protection.
· Following LCA major principles and framework; (ISO 14040).
· Interface with the user: Transparency of data, ability to modify data, clear methods of presentation of the results.
Of the tools that had been examined in this analysis not one tool was found as meeting all the above criteria. Different tools can be used at different phases of planning; one single tool, however, would be more efficient.
