Scope and Objective
The objective of the study is to provide ANEC with a background paper on environmental and health-related criteria for buildings. The back ground paper shall be the basis for developing a European set of environmental and health-related indicators.
The study shall support ANEC in position finding processes and enable to shape upcoming discussion on these issues. Key criteria were selected from a consumer's perspective account by focussing on familiar information (e.g. NOx emission rather than acidification indicator for central heating burner). However, the potential readers of the study are expected to be experienced in the topics of assessing the environmental performance of buildings.
In order to do so the study at hand presents an analysis of the problem of the Commission’s numerous initiatives, reveals new perspectives, and principle solutions.
It was not the aim of the study to elaborate a detailed complete criteria and indicator catalogue for an assessment method to be used in CEN/TC 350 or in EU Ecolabel for buildings as such.
The first approach was a consideration of several existing building assessment systems with special attention to the communalities. The following technical guides and references to building assessment systems were considered:
- EU Eco-Label

Building assessment systems may use similar indicators but conceptually handle them differently. These different approaches should be described with their advantages and disadvantages and conclusions drawn about which concept would be useful for consumers.
Next step was the choice of indicators that had to be exemplified. It led to the following categories for which an in-depth analysis was carried out:
- Life cycle assessment (LCA) with focus on building material
- Energy demand and CO2
- emissions with focus on operation phase
- Emissions on construction site
- Chemicals in building materials / indoor air
