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

Abstract

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 New-Solutions4OldHousing 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.

A Stochastic Approach to LCA of Internal Insulation Solutions for Historic Buildings

“…Exemplary environmental and economic assessments of internal insulation solutions have been carried out for some building case studies [14].The 3encult project developed passive and active solutions aimed at combining both the instance of conservation and of energy retrofit [15]. The NEW4OLD project was aimed at facilitating the integration of renewable energy and energy efficiency technologies into historic buildings and at contributing to their protection [16].In the context of these projects, innovative insulation materials have been also developed and tested to verify their thermal performance and suitability for historic buildings, in terms of easy application, reversibility, and material compatibility [17,18]. However, none of these projects was especially focused on internal insulation solutions, also aiming at developing "probabilistic" approaches for the assessment of their performance from energy, economic and environmental points of view, as made in the RIBuild project.With the growing demand in the energy and climate mitigation targets, the number of LCA studies in the building field increased significantly, as shown by the recent reviews reported in [19][20][21].…”
