The complicated nature of indoor environmental quality (IEQ) (thermal, visual, acoustic comfort, etc.) dictates a multi-fold approach for desirable IEQ levels to be achieved. The improvement of building shells’ thermal performance, imposed by the constantly revised buildings’ energy performance regulations, does not necessarily guarantee the upgrade of all IEQ-related aspects, such as the construction’s acoustic quality, as most of the commonly used insulation materials are characterized by their low acoustic performance properties. From this perspective the SUstainable PReconstructed Innovative Module (SU.PR.I.M.) research project investigates a new, innovative preconstructed building module with advanced characteristics, which can, among other features, provide a high quality of acoustic performance in the indoor space. The module consists of two reinforced concrete vertical panels, between which the load bearing steel profiles are positioned. In the cavity and at the exterior surface of the panel there is a layer of thermal insulation. For the scope of the analysis, different external finishing surfaces are considered, including cladding with slate and brick, and different cavity insulation materials are examined. The addition of Phase Change Materials (PCM) in different mix proportions in the interior concrete panel is also examined. For the calculation of the sound insulation performance of the building module the INSUL 9.0 software is used. The results were validated through an experimental measurement in the laboratory in order to test the consistency of the values obtained. The results indicate that the examined preconstructed module can cover the sound insulation national regulation’s performance limits, but the implementation of such panels in building constructions should be carefully considered in case of lower frequency noise environments.

In this study, the decay potential of wooden elements above ground in Greece is investigated. The presented analysis is based on the daily climatic data measured over a period of 20 years (1985–2004) for 33 sites spatially distributed over the country. The method employed for the estimation of the decay potential is primarily the widely used Scheffer index. The estimated decay potential at the examined sites and its spatial distribution over the country are discussed, while its correlation with the climatic data is investigated. A map depicting the spatial distribution of the relative decay potential in Greece is produced. According to the classification proposed by Scheffer, most of the sites belong to the “low decay potential” category; more severe conditions prevail at a few sites in western Greece. Additionally, an estimation of the decay potential at the studied sites is attempted via another approach, i.e., climatic dose-based, where two existing dose-response models are applied. In the context of this approach, which is based on, among others, the moisture content and temperature of wood, the contribution of air relative humidity to the investigated decay potential is also taken into consideration. The differences among the estimations produced by different methods for the decay potential in Greece, as well as the sensitivity of the results to various climatic factors for a relatively warm climate such as that of Greece, are analyzed. Furthermore, indications derived for the temporal trend of the decay potential at the examined sites are presented.

An estimation of moisture loading severity for building components in Greece was attempted. Annual driving rain indices were calculated for 31 stations spread all over the country, based on the average annual rainfall and wind speed values derived from data, published by Hellenic National Meteorological Service. The analysis revealed that the majority of the locations are sheltered from driving rain. A driving rain map for Greece was produced. A second set of annual driving rain indices were calculated for these sites, based on average monthly data. The relationship between these two sets of indices for the 31 locations was best approximated by a hyperbolic function. Thessaloniki, a city in northern Greece, was further studied using average annual and daily data provided by the Institute of Meteorology and Climatology, A.U.Th. For Thessaloniki, the exposure estimated from daily data was bigger than the one resulting from annual data. Finally, a moisture index for the comparison of building components' exposure to moisture, with the drying potential also being considered, was calculated for the 31 sites studied and a ranking of these sites' climates in terms of moisture loading on buildings was obtained. The drying potential's contribution to this ranking is very important.
