    Renovating post-first-energy-regulation housing: achieving nearly zero-energy buildings under typical and extreme warm conditions in a temperate european city

    Decarbonising the built environment is essential for achieving the 2050 European objectives. Multi-family buildings comprise nearly half of Europe’s building stock, yet there is no regulation mandating all housing renovations to be Nearly Zero-Energy Buildings (NZEBs). This paper highlights the role of NZEB renovation for residential buildings constructed between the first energy regulations, after the first oil crisis, and the EPBD 2002 implementation (post-first-energy-regulation housing), as a pivotal factor towards energy transition. In Spain, this period (1980–2006) encompasses approximately 45% of existing dwellings. A case study was conducted in a city with a Cfb temperate climate, focusing on the most representative residential typology of the target period: the linear block. The study evaluates its current state and defines potential measures to meet NZEB requirements, achieving zero consumption when renovation of thermal envelope is combined with heat recovery systems, heat pumps, and PV panels. This research is based on energy simulations for two climate scenarios: the typical meteorological year (TMY, official series 1970–2000) and the most extreme warm year (EWY, 2022) in Spain. Results indicate active cooling systems are necessary for NZEB renovations in Spanish Cfb climates. Furthermore, low-temperature radiators significantly reduce heating consumption, while splits are the most suitable cooling systems. This study shows Spain is not adequately preparing its housing stock to face climate change, as most typical renovation works are based on official weather files that need updating to reflect harsher summer conditions. Finally, the study aims to encourage new policies and enhance existing regulations to address rising temperatures and heatwaves.

    The effects of architectural heritage conservation on social problems. The case of the Palace of the Marqués de Rozalejo
    (Springer Nature, 2022) Beneito, L. (Lourdes); Torres-Ramo, J. (Joaquín)
    It is now widely recognised that cultural heritage contributes to the development of tourism and urban preservation. Nevertheless, the effects of architectural heritage conservation could go further by helping to resolve social problems. The case of the Palace of the Marqués de Rozalejo (in Pamplona, Navarra, Spain) is analysed in order to explore the potential that appropriate rehabilitation offers. First, the historical and present-day context are explained. Social problems in relation to the building, its neighbourhood, and the citizens of Pamplona are analysed. On this basis we draft a proposal, accompanied by a feasibility study, emphasising its strengths and weaknesses. Finally, conclusions are drawn, taking long-term and short-term considerations into account. They show that, first and foremost, architecture is a service to society and, consequently, cultural heritage should respond to real needs.
