As a large proportion of housing stock does not meet the current demands for energy and comfort (leading to high levels of obsolescence and vulnerability), the annual rate of energy upgrades for the existing stock must be increased. The AURA Strategy is an intervention methodology which focuses on the regeneration of neighbourhoods or obsolete urban fabrics which suffer from high levels of architectural, urban and socio-economic vulnerability. Within this context, the AURA 3.1 prototype was developed for the Solar Decathlon Europe 2019 Competition. The project was based around a sustainable construction strategy for the urban regeneration of obsolete residential neighbourhoods, through the reuse of existing buildings considering Mediterranean climate and energy. The Poligono San Pablo neighbourhood was chosen as the case study. This article presents the main retrofit action: the juxtaposition on the existing building of a structural-architectural system which provides new technological and spatial features. Quantitative data regarding the validity and effectiveness of the AURA Strategy could be collected from the monitoring of the Pavilion prototype during the competition. Two first prizes were won in contests with on-site measurements: Comfort conditions and House Functioning. Third place was also obtained in the Sustainability contest, thus confirming the enormous possibilities the AURA Strategy has for sustainable urban regeneration in retrofitting social housing, within the limitations of the competition.

由于大部分住房存量不能满足当前对能源和舒适度的需求（导致高水平的陈旧和脆弱性），因此必须提高现有存量的能源升级年率。AURA 策略是一种干预方法，重点关注社区或过时的城市结构的更新，这些结构、城市和社会经济的脆弱性程度很高。在此背景下，AURA 3.1 原型是为 2019 年欧洲太阳能十项全能竞赛开发的。该项目基于可持续建设战略，通过考虑地中海气候和能源对现有建筑物的再利用，对过时的住宅区进行城市更新。Poligono San Pablo 社区被选为案例研究。本文介绍了主要的改造行动：在现有建筑上并置的结构-建筑系统提供了新的技术和空间特征。有关 AURA 策略有效性和有效性的定量数据可以从竞赛期间对展馆原型的监测中收集。在现场测量竞赛中获得了两个一等奖：舒适条件和房屋功能。在可持续发展竞赛中也获得了第三名，从而证实了 AURA 战略在改造社会住房方面具有巨大的可持续城市再生潜力，在比赛的限制范围内。有关 AURA 策略有效性和有效性的定量数据可以从竞赛期间对展馆原型的监测中收集。在现场测量竞赛中获得了两个一等奖：舒适条件和房屋功能。在可持续发展竞赛中也获得了第三名，从而证实了 AURA 战略在改造社会住房方面具有巨大的可持续城市再生潜力，在比赛的限制范围内。有关 AURA 策略有效性和有效性的定量数据可以从竞赛期间对展馆原型的监测中收集。在现场测量竞赛中获得了两个一等奖：舒适条件和房屋功能。在可持续发展竞赛中也获得了第三名，从而证实了 AURA 战略在改造社会住房方面具有巨大的可持续城市再生潜力，在比赛的限制范围内。
