Approaches to renovation interventions in the Netherlands, proposals for Rome chapter 4 --------------------------------------------------------------------------------------------------------------------- (direct) financial support, they developed effective processes to manage renovation projects. A number of housing estates from the 1960s and the 1970s have already been subjected to physical renovation. Some of these initiatives are considered good examples of renovation as it is shown by the National Renovation Prize (NRP), a well-known prize awarding successful renovations in the Netherlands. The NRP has had already 11 editions; the latest one in 2007 (see www.nationalerenovatieprijs.nl) Renovation on the building level often consists in re-adapting the existing housing supply. Physical transformation types like combination of existing housing units and/or addition of new dwellings (on the top floor, at the bottom, to the top-end) are common solutions in the Netherlands Branders et. al., 2000). Re-organization of existing accessibility (to the building, the dwellings and the shared spaces) by means, for example, of new elevators or addition of galleries or loggias are common solutions as well. From a technical perception, improvements regard new technical equipments, better thermal and acoustic insulation, new claddings and window frames and double or even triple glazing. The site of the National Renovation Prize (NRP), a well-known prize awarding best practice of renovation in the Netherlands, provides an overview on many projects realized in the recent years. Some of them are characterized by the conversion of their initial appearance into a different one: ‘change the old, bad image into something completely new and modern’ (Gooijer and Te Velde, 2007 in Andeweg, 2007). This reflects the standard approach to renovation, typically dominated by interventions aiming at improving the quality of the building, meanwhile emphasizing its initial and most relevant architectural characteristics (like Complex 50 Tab.10 Section 4.1.1 and Florijn Noord in Chapter 6). On this concept van Schagen architekten, a very well-known and experienced architectural firm, based his design for transformation of deprived social housing states. A number of their projects are presented in the next section 1 . Examples in which the initial look of the building is profoundly transformed are not very common the Netherlands (see Tab. 4). In the Netherlands, renovation practice typically reflects two types of strategies, ‘renovation light’ and ‘high-level renovation’. Both of them intend to improve the initial building quality. High-level renovation, however, is more profoundly and leads to higher quality by moving the walls to improve, for example, housing differentiation. Clearly, for implementation of high-level renovation, tenants need to move out during the works. A good example of such a relevant transformation is the case of the Complex 50 in Amsterdam (see Tab.10). 4.1.1) TEN EXAMPLES OF RENOVATION There are a lot of examples of renovation projects in the Netherlands. With this respect, the research project ReUrbA 2 (Restructuring Urban Areas) published a collection of principles and types for transformation of the urban environment to meet new demands of the society. The most interesting sources of information on the subject are the mentioned National Renovation Prize (NRP). Being a bi-annual competition awarding good examples of renovation, it provides an exhaustive overview of the recent renovations implemented. To select the projects showed in this section the archive of NRP was consulted together with the proceedings of the European funded research Cost C16 (entitled “Improving the quality of the existing urban building envelopes”) and internet sites of architectural firms involved in renovation (like van Schagen, Duinker van der Torre, ANA, D&E and so on). With this respect, it needs to be emphasized that the examples of renovation in the tables do not aim at a complete outline of the situation of social housing renovation in the Netherlands. Further in-depth investigations should be done to provide this, like systematic analyses of best practice for renovation as “examples of actions which could be recommended for further application whether in a similar or adapted form” (Minnery at el. 2000). However, demonstrating best practice is not a simple task (like definition of criteria, indicators, and targets like ‘for whom’ and ‘for what’) (Roumet, 2007). Yet, a good reference can be the research project “Best Practice Analysis of Renovation-Based Strategies” developed by the 1Van Schagen architekten base their office in Rotterdam. Numerous projects have been published on national and international reviews (see also reports of Cost C16).

Approaches to renovation interventions in the Netherlands, proposals for Rome chapter 4 --------------------------------------------------------------------------------------------------------------------- researchers of the Faculty of Architecture at TUDelft. The study focuses on the theoretical and methodical aspects as well as the practical results of best practice evaluation of housing renewal projects in the Netherlands. The research discussed the need for knowledge of renovation based approaches for which analysis of best practices -“examples of action which could be recommended for further application whether in a similar or adapted form” (Minnery et al. 2000) could be used. An analysis of Dutch best practice showed that the mentioned National Renovation Award (Nationale Renovatie Prijs, NRP) is most promising for further analysis (van der Flier & Thomsen 2002 in van der Flier & Thomsen, 2005). To see whether analysis of projects submitted to the NRP gives insight into Dutch renovation and if the variables used are relevant for the selection of best practice, data from four successive entries were analyzed. The data showed interesting tendencies but gave limited insights and it emerged that both quantitative and qualitative factors are relevant to find success and fail factors of the projects (van der Flier & Thomsen 2003 in van der Flier & Thomsen, 2005). Therefore, an assessment of success and fail factors of case studies (three nominees of NRP) was developed. It emerged that effectiveness of the process (goal attainment), and support (from participants) are relevant for success. Four groups of factors are positively related to the success of projects: cooperation of all the relevant participants, innovative and creative solutions to the specific problems, subsidies to make the specific solutions feasible and presence of residents can make the difference between renovation and new construction. More importantly, the efforts of dedicated individuals are often decisive for the success of renovation based approaches (van der Flier & Thomsen, 2005). In the next table are listed the projects analyzed in this study, they were chosen according to three criteria: Time: projects designed or implemented no earlier than 2000 (maximum 7 years old); Recognition: projects awarder-nominated by NRP or mentioned by COST research project; Strategic solutions: projects particularly interesting with respect to the physical solutions adopted. The following table shows a list of the ten projects, their names, date of completion (between 2001 and 2007), building type (high-rise and medium-rise) and tenure after renovation (social rented housing, homeownership, housing for medical care).
