LIFE-PHOTOSCALING’s global objective is to demonstrate the validity of the photocatalytic technology in urban agglomerations, establishing the instruments to scaling up from laboratory measurements to application in our cities, by developing a decision support tool, to assess the sustainability of each particular solution in each particular environment to encourage the widespread use of this technology.

Some attempts have been made in order to apply this technology in a real scale. However, in those cases important problems were encountered to monitor the system from a global point of view that makes it very difficult or even impossible to evaluate if the technique is really working. That is why there is still a barrier that discourages public authorities and most architects and engineers to promote the use of this technology, together with the fact that there is not any compliance criterions’ concerning neither activity nor durability or possible secondary effects.

Therefore, LIFE-PHOTOSCALING intends to bridge the gap between research, policy and widespread implementation of the technology. Their global objective will be met through the following partial objectives:

1: Development of two demonstration platforms (same materials, different emplacements) on an intermediate pilot plant technical scale.

2: Technical development of a prototype for in-situ measuring the photocatalytic efficiency.

3: Development of performance indicators for evaluation of the:

  • Photocatalytic efficiency
  • Durability of the material itself concerning their intrinsic properties.
  • Evaluation of the possible unwanted deleterious effects.

4: Modelling of the photocatalytic processes coupled with the environmental actions.

5: Development of a decision support tool, to undertake the sustainability of each particular solution including a life cycle assessment (LCA).

6: Validation of the tool developed in real –full scale- conditions.

7: Breaking the barriers to the implementation of this technology after having probed safe for human health: communication of the lessons learnt and standardisation efforts.

These objectives would contribute to the implementation of the EU environmental policy and legislation, specified as the objectives and priority areas of the 6th EAP and in the actions and contaminants targeted as priorities in the Thematic Strategy on air pollution, that are those to be reduced by applying photocatalytic technology.
