“…As future work, the present methodology can be extended in more locations in Greece and is able to take into consideration more parameters such as the glazing, building operating schedule, indoor equipment loads, and lighting type. Lastly, it has to be said that the acoustic insulation is also something critical that can be studied [36,37].…”

The most important parameter in the design of the building envelope is the insulation thickness, because it dramatically influences the heating and cooling loads. The objective of this study is the investigation of different insulation scenarios for the four climate zones of Greece and, more specifically, the cities Heraklion, Athens, Thessaloniki, and Florina. The insulation thickness is examined up to 8 cm and the optimum thickness is determined by the minimization of the simple payback period in order to design a cost-effective system. Moreover, the primary energy consumption, the heating/cooling loads, and the equivalent CO2 emissions are calculated. Furthermore, a multi-objective evaluation procedure of the various insulated scenarios is conducted in order to show the relationship between the energetic and the financial optimization. Generally, it is found that the optimum insulation thickness is around 4 cm for all the climate zones using financial criteria, while the energy criteria indicate higher thicknesses. These results can be applied to the suitable design of Greek residential buildings.

“…Lightweight timber construction systems tend to suffer from poor sound insulation, and because there are no reliable mathematical models that can predict impact sound levels new constructions are largely based on previous experiments and measurements [7]. In order to improve insulation, there can be used composite solutions, suspended-ceilings or floating floors but these solutions do not guarantee the achievement of requirements [4,8]. Basic solutions of a typical wooden floor, made of glued timber beams with a solid wooden deck, usually do not meet the requirements of impact sound level and airborne sound insulation.…”

“…On behalf of this paper, comfort is defined as fulfillment of given standards requirements using Single Number Quantities (SNQ). Opening discussion about acoustic requirements for dwellings and hotels is worth to state that used (SNQ) are justified in scientific society [1][2][3] for airborne sound insulation and [4][5][6] for impact sound level. In general, considering measurements of airborne sound insulation, difference of levels is measured and taking into account impact sound level, only sound level from impact is measured.…”

This paper presents evaluation of vibroacoustical requirements in the context of impact and airborne sound insulation in hotel building. This building represents traditional wooden architecture present in southern Poland. Similar structures can be found all around Europe in mountainous areas. Due to fact that there are little information about acoustic conditions of such buildings, this paper gives measured values of sound insulation of typical solutions used in this architecture. In order to define if requirements of current polish standard PN-B-02151-03:2015 for hotel buildings are met, impact sound level and airborne sound insulation of representative partitions were measured. Measurement conducted in presented building shows issues connected with non-sufficient airborne sound insulation of internal partitions-timber log walls. Due to its low mass and, in simplification, homogenous structure, its sound insulation is far from meeting requirements. Considering timber structural ceiling and reinforced concrete floor present in hotel building requirements of impact sound level and airborne sound insulation are met. The solution of weak acoustic conditions of walls is proposed as plasterboard pre-wall with mineral wool inside.

“…As a way to manage floor impact sounds in multifamily housing, floating floor structures are widely used (Kim et al 2009;Vér 1971;Cremer, Heckl, and Petersson 2005;Park et al 2015). Floating floors, which comprise rigid walking surfaces decoupled from the surrounding structure by resilient layers, have high potential for reducing disturbances due to impact noises in dwellings (Schiavi 2018;Caniato et al 2017). Accordingly, considerable attention has been given to estimating the impact sound insulation performance of floating floors (Vér 1971;Gerretsen 1999;Stewart and Craik 2000;Schiavi, Belli, and Russo 2005;e Sousa and Gibbs 2014).…”

With an increasing demand for quieter residential environments, impact sound insulation for floating floors is gaining importance. However, existing methods for estimating the performance of heavy impact sound insulation are limited by their inability to comprehensively analyze various types of floating floors, as well as difficulties mathematically determining the input force of the reference source for heavy impacts. To overcome these limitations, this study proposes empirical models for estimating the sound insulation performance of floating floors under heavy impacts. The proposed models are then validated; the model with the highest accuracy exhibits an average estimation error of 2.73 dB at 50-630 Hz. The proposed models exhibit better accuracies than existing analytical models for frequencies below 100 Hz, where the estimation errors of the analytical models were large. Thus, the proposed models may help reduce errors in analytical estimates or when estimating a single numerical quantity for sound insulation rating during the design stage of multifamily housing.
