Energy and Lighting Performance of Buildings in the Neighbourhood Ciudad de los Angeles, Before and After Refurbishing.

The Spanish Ministry of Economy and Competitiveness is funding the SHERIF Research Project, which falls under the INNPACTO pr ogram. This project aims to increase the rate of the existing building refurbishment fro m the energy efficiency point of view by designing a facade system that must be an economica l, flexible and integrated solution 1 . Under this project has been performing several task s regarding the constructive characterization and energy evaluation of the therm al behaviour of facades on existing buildings . In order to perform the latter task, in which this article will focus, has been developing a survey of various buildings in the nei ghbourhood Ciudad de los Angeles, which has as main objective the comparison between the ac tual energy and light behaviour of different buildings, prior and posterior to any ref urbishment works have been undertaken. The evaluation of the actual performance of buildin gs before and after being refurbished is aimed to determine the impact of the work developed as well as learn from the work performed for future interventions.
