Effect of Nd doping on the crystallographic, magnetic and magnetocaloric properties of NdxGd3-xCoNi
(AIP Publishing, 2023-06-05)
The crystal structure, magnetic and magnetocaloric properties, and the critical behavior of representative compounds in the pseudo-ternary NdxGd3-xCoNi series have been investigated (x = 0.15, 0.5, 1.0, 1.5). All these ...
Control strategy optimization of a Stirling based residential hybrid system through multi-objective optimization
(Elsevier, 2020-02-20)
Hybrid systems for space heating and Domestic Hot Water (DHW) production are an attractive option for buildings to decrease their CO2 emissions. In this research, the operation variables of an installation, composed of a ...
Collective and non-collective molecular dynamics in a ferroelectric nematic liquid crystal studied by broadband dielectric spectroscopy
(AIP, 2023-10-23)
A great deal of effort has been recently devoted to the study of dielectric relaxation processes in ferroelectric nematic liquid crystals, yet their interpretation remains unclear. In this work, we present the results of ...
Mathematical development of an average method for estimating the reduction of the Heat Loss Coefficient of an energetically retrofitted occupied office building
(Elsevier, 2019-03-07)
The performance gap between the design energy consumption of buildings and their real energy consumption has three main sources: the energy systems’ performance, the users’ behaviour and the buildings’ envelope performance. ...
Evaluation of green walls as a passive acoustic insulation system for buildings
(Elsevier, 2015-03)
Greenery on buildings is being consolidated as an interesting way to improve the quality of life in urban environments. Among the benefits that are associated with greenery systems for buildings, such as energy savings, ...
Overall uncertainty analysis of zonal indoor air temperature measurement in an in-use office building
(Elsevier, 2022-04-23)
Generally, studies where the zonal indoor air temperature is measured only consider the manufacturers’ sensor accuracy to determine the overall Temperature Uncertainty (UT), without considering other sources of uncertainties ...
Field assessment of thermal behaviour of social housing apartments in Bilbao, Northern Spain
(Elsevier, 2013-06-26)
A field study of 10 social housing dwellings in the north of Spain is presented in this paper. Knowing the building stock is the first step to set up priorities in a global strategy to improve the energy efficiency of the ...
Development of a high-frequency dielectric spectrometer using a portable vector network analyzer
(AIP Publishing, 2024-02-05)
A simple and novel setup for high-frequency dielectric spectroscopy of materials has
been developed using a portable vector network analyzer. The measurement principle
is based on radio-frequency reflectometry, and both ...
Experimental method for estimating the effect of solar radiation on the inner surface heat flux of opaque building envelope elements
(SAGE, 2024-04-10)
There still exists a considerable difference when comparing the real and the design energy consumption of buildings. The difference between the design and the real building envelope energy performance is one of its main ...
A photovoltaic forced ventilated façade (PV-FVF) as heat source for a heat pump: Assessing its energetical profit in nZEB buildings
(Elsevier, 2022-04)
The European Union is changing its energy model towards a more efficient and sustainable one. In this new outlook, the Heat Pump (HP) has become a leading technology in the building energy sector. The use of the air source ...
