The information gathering process went from an amplitude in the first selection of wineries, to a concretion that culminated in 6 field visits during which, projects were gathered to complete the second specific objective. The ammount of information throughout the process was vast and had to be treated, cataloged, some of it analyzed and the rest was stored for further analysis at later stages of the CW project.
Results of the first specific objective
Initially, the yellow pages seemed like a great option for finding wineries. However, the actual number of useful wineries was low (1,236) compared to the initial number (3,836), despite this, it should be noted that 1,112 cellars were eliminated from this database because they were already present in the D.O. database. In addition, when the telephone survey campaign began, 527 wineries in this database no longer existed as a company.
Surveys are very tedious and time consuming for researchers, but qualitative questions revealed key information that led to finding more contacts in the wine industry, which in turn led to 5 complete architectural projects being sourced directly from the designer rather than from the relationships established with the wineries. Other engineering companies showing interest were contacted, but did not provide further projects before the deadline for completing the project collection phase.
Telephone surveys are never as effective as those that are administered in person. Visits to fairs allowed to personally meet many of the interviewees, who communicated the importance of personal interaction when requesting sensitive information. By the time the fairs were visited, the telephone survey campaigns were over. However, as some of the interviewees expressed it, it would have been much faster (a large number of wineries were concentrated in one place) and it would have been easier (face-to-face interaction) to obtain a response to the survey in person and probably the effectiveness of the survey. The campaign would have been greater, both in the number of projects and in the number of surveys.
In the process of obtaining full copies of winery projects, which involved a series of field trips across much of Spain, many drawbacks arose, even when the winery owners / managers had agreed to provide the documents. The problems appeared in the form of incomplete projects, adaptation projects of older non-winery buildings, lost projects, other projects were no longer available at the winery, etc.
The large number of activities described above served the first specific objective, to characterize on a large scale the use of constructive designs and complementary passive bioclimatic strategies in the ageing rooms of Spanish wineries. From this large scale, the number of activities is reduced, but not their importance, since the information filter sifts and yields more concise results. Since this article is about the method, we will not get into the details of the characterization of the wineries will be left out in this paper because that would be an article in itself.
Results of the second specific objective
Once the large-scale characterization was carried out, the next step was to select 5 wineries that fulfilled the second specific objective. Representative wineries were studied in search for bioclimatic solutions in their ageing rooms. For this, the following criteria were used:
- Construction date should be slightly earlier or later than the year 2005, in which the Spanish Technical Building Code entered into force. The above to ensure more comparability among projects.
- Selected wineries should produce more than 30 thousand liters of wine per year, guaranteeing the project of an operation with a greater degree of professionalization.
- That the project includes at least the plans, budgets and design report (a document known as “memoria” in Spanish projects). These documents are essential for the series of calculations and parameters required for the study.
In addition to the aforementioned criteria, the research team decided to choose two basement projects and three aboveground aging room projects, so both types could be more comparable.
The particular cases of the Campo Viejo and Aalto wineries are worth mentioning because the former has received numerous awards for its efficient design and the latter because it incorporates a highly effective technology, which until now has had little adoption in Spanish aging rooms: geothermal energy (although it is not the object of this study). These two extra criteria of choice follow the flexibility afforded by the participatory action research approach (see figure 10).
Results of the third specific objective
Once the wineries were selected and the second specific objective was fulfilled, it was possible to solve the third specific object, which implied a more detailed characterization of the construction aspects in the aging rooms, directly on the selected wineries.
To meet the third specific objective, as shown in the results section, each of the ageing rooms was characterized from the most important points of view identified in the bibliographic research: (i) the typology (buried, above ground, basement, etc.); (ii) orientation; (iii) the form and; (iv) the envelope. Here too for space reasons the full details of the characterization will be left for another article.
3.4 Other results
Result 1. The participatory action research method was extremely successful in gathering information that otherwise cannot be obtained from traditional scholar sources. For this reason, the authors deemed it necessary to publish a web portal (that is constantly being updated) where the results of posterior studies of the materials can be seen through video, plans and other documents. The portal’s web address is as follows: https://bodegasestudio.com/. The web resource has three language options; Spanish, English and Chinese.
Result 2. As mentioned before, a high-quality literature review (Arredondo-Ruiz et al. 2020) was published after the surveying process took place. This knowledge also helped shape objective 3 and gave a deep insight into the subject matter of bioclimatic architecture in ageing rooms.
