ASSIMILATE Assessment of Seismic Safety Integrated with Machine Learning and Tr...

Impact of heating strategies in LSF building systems: evaluation of thermal com...

The importance of simultaneously good thermal performance and high energy efficiency is a relevant and current challenge in residential buildings. In southern European countries, the use of heating systems is often limited by a phenomenon called energy poverty. In this context, the challenge of aspiring sustainable constructive solutions, which optimise the thermal performance of buildings, is even more urgent....

Study of Mortar Formulations for Underfloor Heating Systems Incorporating Steel...

Considering the European targets for energy efficiency and decarbonization, without compromising thermal comfort, it’s necessary to define more efficient and sustainable air conditioning solutions, in terms of design, use of materials and even system efficiency. Improving the thermal properties of mortars used in underfloor heating systems is a promising strategy for increasing the thermal and energy efficiency...

Thermal Performance of Multifunctional Facade Solution Containing Phase Change ...

This work focuses on the development and analysis of a new multifunctional facade panel incorporating PCM in foam layers. The thermal performance was analysed recurring to a hotbox heat flux meter method to determine the thermal transmittance (U-value) and the main findings are presented. The experimental setup was based on the steady-state approach, using climatic chambers, assuring a stable thermal environmen...

Failure mechanisms and behaviour of adobe masonry buildings: a case study

Non-linear static analyses are amongst engineering community one of the most common analysis approaches for the seismic assessment of existing buildings, due to a good trade-off between information needed and results produced to assess structural safety. Pushover analyses, in fact, can provide hindsight onto structural behaviour well into the non-linear range, up unto conditions of collapse initiation and struc...

Impact of heating strategies in LSF building systems: evaluation of thermal com...

A importância de compatibilizar um bom desempenho térmico com uma elevada eficiência energética é um desafio relevante e atual nos edifícios residenciais. Nos países do sul da Europa, o recurso aos sistemas de aquecimento é, muitas vezes, condicionado, por um fenómeno designado por pobreza energética. Neste contexto, o desafio de procurar soluções construtivas sustentáveis, que otimizem o desempenho térmico dos...

Experimental and numerical analysis of the thermal performance of polyurethane ...

The potential thermal regulation effect of rigid polyurethane (RPU) foams can be enhanced by the incorporation of phase change materials (PCM). The main goal of the present work is to evaluate the thermal characteristics of RPU panels using two different types of PCM (a commercial one and another based on paraffin and calcium carbonate) and to quantify their potential as thermal regulators of indoor spaces. The...

An innovative approach for temperature control of massive concrete structures a...

This study proposes a new methodology for the embedment of flexible PVC hoses (with the shape/geometry of the intended cooling pipes) that allows their removal a few hours after casting (i.e. after setting), while allowing that water is pumped through the circular cavity afterward (through a flexible/impermeable sleeve placed to shield the exposed concrete cavity). The PVC hoses are initially filled with oil un...

Análisis del efecto de materiales de cambio de fase sobre la demanda de calefac...

RESUMEN: Este trabajo evalúa el efecto que tiene la integración de materiales de cambio de fase (MCF) en la envolvente de los edificios, sobre la operación de un sistema de generación solar fotovoltaica acoplado con bomba de calor para cubrir las necesidades térmicas de dicho edificio. A partir de una instalación a escala real, se han realizado modelos en EnergyPlus de diferentes escenarios de estudio intermedi...
