Pavener project:

Pavener project aims to developing a system for collecting the solar energy absorbed by asphalt paved surfaces. Asphalted paved surfaces can heat up 70 degrees in days of strong sunlight. This energy can be used for heating systems, air conditioning systems or hot water supply. The system would reduce consumption of fossil fuels, as well as greenhouse gas emissions to the atmosphere. Structural stability and thermal behaviour are the key aspects to consider in the development of the system. Pavener is two-year project is being led by the Campezo Group, based in Spain.
