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 ...
Energy and economic assessment of the envelope retrofitting in residential buildings in Northern Spain
(Elsevier, 2014-10-18)
In this paper, potential energy savings by implementing different energy saving methods to enhance the building envelope are presented and calculated through transient simulations using TRNSYS software. To do that, a ...
Modelling, experimental characterization and simulation of stirling engine-based micro-cogeneration plants for residential buildings.
(2019-04-10)
El sector de la edificación representa aproximadamente el 40% del consumo de energía y un 36% de las emisiones de CO2 en la Unión Europea. En la actualidad la investigación se dirige hacia la mejora de la eficiencia ...
Effects of individual metering and charging of heating and domestic hot water on energy consumption of buildings in temperate climates
(Elsevier, 2018-06-14)
Individual metering and charging of heat and domestic hot water is one of the possibilities for reducing the energy consumption in existing multifamily buildings and, with this aim in mind, the EU-directive 2012/27/EU ...
Influence of the regulation framework on the feasibility of a Stirling engine-based residential micro-CHP installation
(Elsevier, 2015-04-07)
In this paper an economic analysis of a 1 kWe Stirling engine-based micro-CHP (combined heat and power) residential plant is developed, approaching the case of a Spanish detached house sited in a cold climatic zone. The ...
Parametric study of the operational and economic feasibility of Stirling micro-cogeneration devices in Spain
(Elsevier, 2013-12-19)
This paper analyses the operational and economic viability of Stirling engine-run micro-cogeneration units in single-family houses in Spain. Thermal demands for the reference dwelling, sited in three different and ...
Development and comparative analysis of the modeling of an innovative finned-plate latent heat thermal energy storage system
(Elsevier, 2013-09-01)
This paper presents an innovative finned-plate latent heat thermal energy storage system for its integration in cogeneration systems. For optimization purposes it is very important to maximize the efficiency of the ...
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. ...
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 ...
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 ...
