The research set up Chapter 1 --------------------------------------------------------------------------------------------------------------------- 1.1.4) CITY LEVEL: ROME According to Federcasa (the Italian Association for Housing), housing institutes in Italy can be grouped into three categories according to maintenance and investment strategy: 1) profound maintenance reduction and zero investments; 2) moderate reduction of both maintenance and investments; 3) moderate-high maintenance and investments (Pozzo, 2005). This research focuses on one of the biggest Italian housing institute, ATER that belongs to the first group. ATER Roma (Azienda Territoriale per l'Edilizia Residenziale pubblica, Territorial Institution for Social Housing) is the only housing association in the city of Rome and one of the seven in the Lazio Region. ATER Roma was chosen for two main reasons. For ATER, it might be beneficial to analyze its structure and provide directions for improvement on the basis of the Dutch model, since the institute is in severe financial and bad managerial conditions However, recommendations might apply to other institutes as well. Secondly, it is one of the most urgent Italian cases in need of solutions regarding both processes and products. This aspect is particular important because there is currently a huge housing shortage in the city of Rome and this situations is worsened by the decaying conditions of the stock managed by ATER Roma. Because of an intervention approach based on the “emergency approach”, most of the housing stock owned and managed by ATER Roma is in poor conditions. The low maintenance level implemented over the last years is the cause of a decrease in both technical and functional quality of the stock. An update to nowadays requirements is needed as well. The strategies so far applied by the housing institute and the local municipality are insufficient to solve the mentioned problems. This might be explained by two factors. Firstly, there is a general lack of knowledge in terms of successful methods and tools for renovation of social housing estates. Secondly, there are no (strategic) management strategies for renovation processes. This situation worsened due to the recent change in legal form as housing institutes were forces to change from “public housing organization” (organizations with public function financially supported by the government) to “economic public company” (companies with public function) (see Chapter 3, Section 3.1, General developments in Italy). After the mentioned ‘devolution’ process, the company was unable to adapt its structure to these legal changes. It is now incapable to develop and implement maintenance (and renovation) strategies. To support a more strategic decision making, tools and methods are very much needed. 1.2) RESEARCH SET-UP 1.2.1) THE PROBLEM This research concerns processes and interventions strategies for renovation of deprived large social housing estates. In particular, it focuses on the residential blocks built between the ‘60s and the early ‘80s with prefabricated concrete technologies; the so-called panel multifamily blocks. Description of the problem At the European level, renovation of deprived social housing estates is often conducted on an ad hoc base, rather than occurring in an integral intervention framework. The recently set energy saving goals of the European Committee requires innovative strategies for the improvement of energy consumption of the existing stock.. The significance of the building envelope has been widely recognized as relevant in energy consumptions, building decay and expenses for maintenance. Unfortunately, despite its clear 6. A
The research set up Chapter 1 --------------------------------------------------------------------------------------------------------------------- potential, there is a lack of approaches integrating the range of possible envelope-related physical solutions. In Italy, renovation in general is far from being implemented in the life-cycle of dwellings. With a few exceptions, the most common approach focuses on maintenance at the minimum acceptable quality, i.e. the original quality when newly constructed.. In case of Rome, interventions tend to be driven by the “emergency approach”: temporary and superficial physical measures to solve severe and extended problems. The technical and functional qualities of the social housing stock worsen over the years, especially of those estates realized between the ‘60s and the ‘70s of the former century. The housing institute is at the same time in severe financial and managerial conditions. There is a need for a more strategic renovation approach and for tools to improve effectiveness of decision-making. Such issues are particular important given the current housing shortage in Rome. Dutch housing associations have been developing strategies to deal with renovation on neighborhood and building level. They developed effective processes to manage such projects. A number of housing estates from the 1960s and the 1970s have already been subjected to renovation. Some of these initiatives, although far from being envelope directed approaches, are considered good examples of renovation. This is extensively shown in the site of the National Renovation Prize (NRP), as stated a well-known prize awarding successful renovations in the Netherlands, just having awarded the 11the edition of the biannual prize. Insight into the Dutch context could be necessary to understand ‘why’ and ‘how’ such renovation projects are being implemented to end up with recommendations on possible intervention strategies for ATER Roma in particular, and to the Italy in general. Summarizing the described situation, the problem definition might be described as follows: The housing shortage and decaying condition of the post-war social housing stock owned by ATER Roma stem for poor and ad-hoc maintenance and investment decisions and this situation might be improved by an innovative intervention strategy that might be developed after the framework of the Dutch renovation strategies. 1.2.2) AIM OF THE RESEARCH and CENTRAL RESEARCH QUESTIONS This research refers to a broader concept of renovation that according to Thomsen is a “transformation (process) of the physical, functional, financial, architectural and ecological characteristics of a building product or project (product) to realize a comprehensive and useful extension of the life span” (Thomsen, 2001). The aim of this study is to recommend on directions for the improvement of the intervention strategy of ATER Roma for its post-war housing stock. In particular, the objective is to provide a framework of physical measures for renovation directed to the building envelope to support decision making of the housing association and other parties. This will be achieved by structuring a matrix addressing strengths and weakness of each physical measure. 7. A
