“…Previous studies (De Rosis et al, 2014;Tinti et al, 2014;Barbaresi et al, 2015a;Verdecchia et al, 2016) allowed to use the energy model of an Italian winery as base model for the present work. The model was calibrated and validated on experimental data on an existing winery (Barbaresi et al, 2017).…”

Referring to the wine sector, in the Mediterranean area, most of the wine farms make use of unconditioned above-ground buildings constructed without a specific attention to temperature control, where indoor temperatures easily show trends in disagreement with correct wine-ageing and conservation. Moreover the suitable temperature ranges can differ from wine to wine, and are considerably different from ideal temperatures for human comfort. This study aimed at testing the effectiveness of different architectural elements in improving the thermal behaviour of unconditioned farm buildings, by means of energy simulations validated on an Italian case-study, comparing the data provided by the simulations with different temperature ranges. Results showed the building thermal performance depends on the chosen intervals, some solution played negative or positive role according to the analysed range and in general roof and wall interventions were more effective than orientation and solar shading, and the combination of more strategies allow to achieve improved results.

“…The annual wine production amounts to 170,000-220,000 L. The main building (30 m long, 20 m large, and 5 m high) of the farmstead houses both winemaking and wine storage. Previous studies Tinti et al, 2014;Barbaresi et al, 2015) allowed the research group to collect both general information about this farm and more specific data about its winemaking process. Based on that information, the production data of Table 1, derived by doubling the actual extension of the vineyards, have been assumed as input data for the modelled winery.…”

Since the Nineties of the previous century winery design has been undergoing deep changes. Some factors are affecting the main design criteria, focusing on a new conception where the winery becomes more and more open to customers, energy demand reduction is a crucial goal driven by economic and environmental reasons, and the whole systems is aimed at the research of a renovate quality of the product.The state of the art in this specific sector highlights how a reduction of the energy consumed by a winery can almost reduce to zero the carbon emissions of the whole wine-making process, as well as the existing lack of specific design criteria addressing the most recent above-mentioned trends and challenges, in particular for small and medium-sized farms, that on the whole account for a huge production in the Mediterranean area. The main aim of this work is to provide information about yearly thermal demand in the wine-making sector, by means of an integrated approach that considers the thermal loads required by room heating and air conditioning, must/juice pre-cooling, and fermentation cooling. Different models have been created and tested on a case study, in order to analyse the contribution of various farm design choices to the total energy demand. The most representative models are described and analysed in this work: they differ for harvesting modality, and materials and vertical distribution of the building envelope (aboveground vs underground).The results highlight the relevance of the three contributions in terms of total annual energy consumption, power peaks, and time distribution of energy demand over the year. The analysis of the data obtained by the different models have allowed to identify the strengths and potential critical issues, and to provide professionals, oenologists and farmers with useful elements to lend support in their decision making processes, as well as to define the next steps of the research, aimed at defining specific design criteria for small and medium-sized wineries. IntroductionOne of the most challenging phases in winery design concerns the integration of all the disciplines involved in the project, and the management of their mutual relationships. An integrated design should be able to assess the main consequences of the various choices, made in relation to a specific design sector, on all the other sectors. Winery design should involve several knowledge fields, such as engineering, architecture, oenology, meteorology, chemistry, physics, which are often addressed separately by different professional figures, thus increasing the risk of inaccurate building and system sizing and design.The production of wine is a complex process made by several operations, such as grape cultivation, harvesting, delivery, and pressing, must fermentation, wine storage, and bottling. As every other transformation process, winemaking produces an environmental impact due to the use of chemical products (in the field and in the winery), to electric energy consumption for production and tempera...

SUMMARYThe wine production process has a high energy demand of about 1,750 million kWh per year in the EU. Saving energy, responsible consumption and efficient use of energy sources are key aspects to consider for the competitiveness and viability of the sector. Therefore, the TESLA project (Transfering Energy Save Laid on Agroindustry), funded by the European Commission, has conducted 39 energy audits in wineries from four countries (Spain, France, Portugal and Italy). The information collected has allowed them to carry out a comparative analysis of energy efficiency measures through a technical-economic study, calculating the period of return on investment and performing a sensitivity analysis to determine the break-even point for each of the investments analysed. The results show that the replacement of chillers by more efficient ones, the installation of variable speed drives on pumps, the introduction of management and control measures such as the implementation of a Building Management System (BMS) and the installation of energy analysers for identification of consumption by use are the measures that have the greatest quantitative impact. RESUMONa União Europeia, o consumo anual de energia associado à produção do vinho é de cerca de 1,750 M kWh. A poupança de energia, o consumo responsável e o uso eficiente do recurso energia são aspetos chave a considerar para a competitividade e viabilidade do sector. Deste modo, o projeto TESLA (Transferring Energy Save Laid on Agroindustry), financiado pela Comissão Europeia, realizou 39 auditorias em adegas localizadas em quatro países (Espanha, França, Portugal, Itália). A informação recolhida permitiu realizar um estudo comparativo das medidas de melhoria de eficiência energética do ponto de vista técnico-económico, através do cálculo do período de retorno do investimento e de análise de sensibilidade para determinar o ponto de equilíbrio para cada investimento analisado. Os resultados mostram que a substituição de chillers antigos por outros mais eficientes, a instalação de variadores de velocidade nas bombas e a introdução de medidas de gestão e controlo, tais como: a implementação do sistema de gestão de edifícios e a instalação de analisadores de energia que permitem a identificação do consumo por etapa, são as medidas que apresentam maior impacto do ponto de vista quantitativo.
