A comprehensive investigation regarding the hygrothermal behavior of a constructive solution containing phase change materials (PCMs) was performed on full-scale test cell, divided into two similar compartments. This involved monitoring (indoor air temperature) compartments, in which one had PCM incorporated floor mortar. The main goal this research to investigate potential kind for overheating mitigation. numerical study conducted using EnergyPlus® software (version 9.0), exploring...
Given the precarious conditions observed in large Latin American cities; especially metropolitan areas; and disconnection between urban built natural environment surrounding them; there is a call for action; from intervention territory already consolidated; to development of future cities through sustainable criteria.
The incorporation of phase change materials in movable structural cells shading elements associated with southward-facade windows is evaluated this article. proposed material–shutter a thermal energy storage system designed to take advantage solar for winter nighttime indoor heating. A two-dimensional phase-change heat diffusion model based on the enthalpy formulation was considered. numerical follows finite-volume method fully implicit and allows alternating melting solidification material...
Nowadays, the rising gap between global energy supply and demand is a well-known circumstance in society. Exploring solution to invert this tendency leads several different scenarios of saving strategies that can be improved using phase change materials (PCM), especially cold-formed steel-framed buildings. The present research reports overheating (indoor air temperature above 26 °C expressed as an annualized percentage rate) reduction south-oriented compartments performance detached house...
The evolution of the construction sector over years has been marked by replacement high thermal inertia mass constructions increasingly lighter solutions that are subject to greater fluctuations and, consequently, discomfort. To minimize these effects, energy demanding space conditioning technologies implemented, contributing significantly sector’s share global consumption. Enhanced constructive involving phase-change materials have developed respond loss, influencing buildings’ and...
Improving the energy efficiency of new and existing building stock while fostering use renewable is one major goals Renovation Wave initiative promoted by European Union. In this framework, present research focuses on design an innovative efficient construction solution for external envelope internal partitions that can improve thermal comfort in lightweight technology buildings. The phase change materials (PCMs), particularly macroencapsulated form, solutions or components enhances...
A noise barrier design of the absorptive type, incorporating LECA®, a well know material used in civil engineering because its above-average sound absorption characteristics, as coating material, is presented. The performance was tested experimentally, using situ measurements at Highway A2 Portugal, and theoretically with MicroBruit, computer program for traffic prediction. In general, results indicate that barriers made from concrete coated LECA® yield similar to those obtained uncoated...

The noise resulting from stopping a moving train is often source of annoyance to both passengers and people who work sometimes live in the vicinity railroad stations. present study attempted define characteristics produced by brakes trains used Portugal. braking process varies widely within same type train. Therefore, results measurements had be statistically analyzed. parameters describe this situation were LAeq, L10 L90 corresponding took place during daytime nighttime period. Data was...
The financial viability of two major renewable energy technologies, namely photovoltaic and wind energy, were studied for the central region Portugal results demonstrate that whereas systems are still too expensive to implement, system have become an interesting complement conventional systems.
