Installing Opaque Ventilated Facades for Energy Saving in Old Buildings. CLIMA 2016 - proceedings of the 12th REHVA World Congress, 1.ISBN (Electronic)87-91606-26-8 (vol. 1), 87-91606-36-5 (set)https://hdl.handle.net/20.500.14468/24830Many buildings erected more than about thirty years ago lack of an effective facade insulation. Some of them can be seen in old residential neighborhoods, with parts of their concrete structures exposed to outdoor air and sunlight, single pane windows, thermal bridges, etc. Renovation of these facades leads to energy savings and more comfortable and healthy indoor air conditions. An opaque ventilated facade (OVF) is an easy and economic system to reduce heating energy consumption. The main objective of this paper was to obtain the reduction in heating demand in the winter season using OVF’s modules. Another objective was to determine the best location in terms of climate variables to install an OVF system. In order to achieve these objectives, the thermal loads of a building with and without an opaque ventilated facade system were simulated for 12 locations in a European country in the winter season. Energy saving in the winter were found to be positive for all the locations, and the best locations to install an OVF were found to be the southern regions and the coastal areas, which were the ones with the highest levels of solar radiation. It was also found that locations with lower solar radiation levels had lower heating demand values when their temperatures levels were high and/or the average wind speed levels were low.eninfo:eu-repo/semantics/openAccess33 Ciencias Tecnológicas::3313 Tecnología e ingeniería mecánicasactas de congresoheating energy savingsolar energyventilated facadesolar façade
