3.2 How to conduct an LCA study within the field of energy-efficient buildings
Every LCA study generally follows ISO 14040 and ISO 14044, which provide general rules on how to conduct an LCA study – independent of the scope of assessment, type of product or associated industrial sector. They define the separate phases for such studies, and provide general rules for the application of this methodology. The defined…

3.2.1 How to start and proceed with an LCA study
The first step, for both building and product LCAs, is to define the goal and scope of the study. This will determine the type of study that is required, and identify the relevant aspects that need to be considered. The decision tree shown in Figure 8 can help identify the type of study required for…

3.2.2 LCA study set-up: generic template
After selection of the study type and the subsequent filtering of aspects, the LCA study is set up according to general LCA practice, based on ISO 14040/14044. This process is briefly explained below with a generic template of how to set up an LCA study. Step 1: Goal and scope definition The definition of goal…

3.4 How to proceed with the service life assessment in building and product LCA studies
This section introduces the main concepts of service life planning. These are useful for practitioners who intend to carry out an LCA study for product and building One characteristic of LCA studies in the construction sector is the assessment of technical systems that often have very long service lives. Estimations of service lifespans of one…

4 Overview of the aspects covered in the guidance document
In total, 104 important aspects have been identified in the EeBGuide for improving building LCA studies that aim to be compliant both with CEN TC 350 standards and with the ILCD Handbook. G-01 Goal definition for building and product LCA. G-02 Classifying the decision context as situation A, B, and C for building and product…

5.1 Overview
This chapter addresses aspects that are related not to a single building life cycle stage but to several, and therefore represent common LCA questions. Also, these aspects typically relate both to buildings and to products. They provide provisions, rules and guidance for the goal and scope definition, the inventory analysis, the impact assessment and the…
