Abstract

The rehabilitation-revitalization of some old headquarters, situated in Gardeny area in the city of Lérida, consisted of the intervention in three existing buildings and there restructuring in investigation spaces for the university and the food and agriculture business. In project decisions, were considered to be a priority, the buildings energy demand improvement. For it, during the project phase, data processing models and storage of the existing building climatic information were used. The information and calculations fitted project and they have been the base to motorize and to monitor the rehabilitated building. In phase of preliminary design, and to the buildings energy demand improvement, the asoociated energy demand to the constructive and architectural characteristics of the building, were evaluated by means of energy models. The constructive systems solutions, atrium-spaces, and the humidity and vegetation effect, permitted savings around 23% in heating and 50% in cooling. The possibility to integrate a second research team in the project allowed us to arrange on one hand the data of savings and for other one monitoring the existing building. As well we programmed the rehabilitated (and in use) building monitoring. Nowadays, on a developed methodology, bioclimatic strategies are being adjusted to give the ideal comfort to the interiors and intermediate spaces of the buildings.
