Abstract
Wineries present significant interest on a research level, combining Indoor Air Quality (IAQ) issues related with substances emitted through the wine production, as well as the need for minimizing conventional energy consumption (optimizing energy performance). In the proposed work, experimental and theoretical analyses are presented which aim to achieve both targets, that of improved indoor climate and energy performance. An extensive measurement campaign was implemented, regarding indoor climate thermal parameters, as well as concentration of substances (CO2, VOCs, NO2) affecting IAQ. The results of the parameters were exploited for the assessment of indoor climate; moreover, data from indoor thermal parameters together with values of specific parameters related to the efficiency of the individual devices were utilized in the development of the energy model. The model was used to formulate and evaluate proposals for reducing the energy consumption of the winery. The proposals include the use of Renewable Energy Sources (RES) and, in particular, the installation of a photovoltaic array on the roof of the premises. Finally, an economic and technical study was carried out to determine the performance of the suggested interventions and the expected payback period.
Highlights
The discussion about the global warming and the climate change is very intense lately
Towards more environmentally friendly strategies, in [13], the potential of producing biogas from thermophilic anaerobic digestion of winery residue is investigated, quantifying the values of energy that can be produced on the level of the installed wineries in Italy; the results demonstrated that the process could be self-sustaining
The climate of the respective site is characterized as the coldest one, regarding Greece, noting that West3 of 15 ern Macedonia is ranked on D climate zone according to the Greek version of the European Performance of Buildings Directive (EPBD) [26]; rainfall is generally moderate, summers are mild and snowfall is frequent in the winter months
Summary
The discussion about the global warming and the climate change is very intense lately. The Paris Agreement aimed to restrict the global temperature increase, while adopted the so-called 20/20/20 targets of the EU, as they are reflected in the relevant EU. The need for increasing the sustainability of wineries, as well as the important role of research on achieving this aim, is highlighted in [4]. Energy usage in English wineries is reviewed in [5], indicating specific points of the production process where energy efficiency can be implemented. The energy performance of a specific winery in South Italy is investigated in [6]; cooling proves to be the most energy intensive use, while Renewable
