During Light2CAT project three full scale demonstration sites will be deployed with aim of testing the performance of the innovative materials developed in real-life conditions. The following places has been selected:
- DENMARK - Copenhagen - Fælledvej Street (latitude 55° 41' N, longitude 12° 33' E)
- DENMARK - Brøndbt - Holbækmotorvejen Motorway (latitude 55° 38' N, longitude 12° 27' E)
- SPAIN - Valencia - Colon Street (latitude 39° 28' N longitude 0° 23' W)
These locations have been selected based on high volumes of traffic circulation as in presence of traffic-lights, models of static air currents and high sun exposition; conditions which enable reactions for pollutants generation so that, where the performance of Light2CAT materials is optimize and noticeable.
Fully equipped monitoring stations for air quality - measuring NOx concentrations, temperature, relative humidity, sunlight irradiance, UV index and rain meter - are installed for background analyses. Over a period ranging from May 2013 to February 2014, prior the execution of the full scale demonstration, the air quality in the selected areas has been monitored and these values will be recorded for comparison purposes with the period during material’s performance, June 2014 – February 2015.
Finally, all these activities will give a report on final performance indicators, an assessment of the air quality after the execution of the photocatalytic structure, description of the major benefits obtained through the use of photcatalytic concretes in relation to geographical positions, irradiation conditions, influence of seasonal climatic variations, wind and air circulation.
