The results of studying the energy consumption of two hospitals and an outpatient clinic in the city of Huelva are presented, before and after the seasonal changes. The impact of the hourly change has been investigated to ...

In this work is carried out the energy study of a house with the aim of achieving a maximum reduction in energy demand to design a zero consumption building. An energy simulation has been carried out using the PHPP v9.3a ...

Energy efficiency criteria for the design of local urban rehabilitation policies are revised. This study characterises the demand for air conditioning of a series of typical buildings by simulating the influence of climate ...

The integration of renewables into power systems has led to multiple studies and analysis in terms of grid-power quality, reliability, and/or feasibility. Among different resources to be considered as alternative energy ...

Solar irradiation databases from satellite estimates are based on images taken from satellites with wide spatial resolution. The rising interest on solar energy technologies and climate change generates the necessity of ...

The high uncertainty on natural gas prices and the development of concentrated solar energy technologies has generated the expansion of integrated solar combined cycles (ISCCs). Since combined cycle gas turbines (CCGTs) ...

The use of vegetable biomass as fuel requires the determination of various physicochemical parameters that determine operating parameters. Among them, High Heating Value (HHV) which determines the operation temperature and ...

Simulation is a common procedure for the characterization and energy analysis of buildings. Although the simulation tools are continually improving, the energy modelling process is still a specialized work, which entails ...
