Social Rent Housing Refurbishment Demonstrator of LIFE Project “New4Old” (LIFE10 ENV/ES/439)

This ecoefficient renovation of two buildings of social housing for rent is located in the historic center of Zaragoza and has been carried out among 2013 and 2015. It emerges from the conclusions and strategies developed for the NewSolutions4OldHousing project (LIFE10 ENV/ES/439), funded by the European Commission. The general objective of LIFE project is to define the most appropriate methodology for the rehabilitation of social housing with criteria of energy and environmental sustainability and application of innovative technologies to combat climate change. The application of passive strategies in the refurbishment of these Demonstrator Buildings has helped to achieve thermal and lighting comfort with less energy-consumption, with savings above 70% in demand and about 25% in real consumption. These data are particularly relevant when the residents are renters with very limited incomes, vulnerable to problems such as energy poverty. Therefore, the proposed action serves to improve the passive behaviour of the building and to achieve greater thermal and lighting comfort and liability without increasing the financial costs related to energy consumption.
