To address the global energy problem, energy from the solar source remains the most encouraging solution for buildings with a difficult-to-achieve goal such as achieving zero net energy consumption. In a solar thermal system, integrated solar collectors in buildings can convert the absorbed solar energy into thermal energy and can be better exploited in an area of the facade, while acting as an integral component of the building envelope, with good sun exposure. The aesthetic character and functionality of this te...

In the current global context where we talk about the depletion of conventional fuel resources and their impact on the environment, we find that it is necessary to integrate renewable energy sources/resources in new constructions, but also adapt existing constructions in order to reduce energy consumption. This article presents a system with solar thermal collectors combined with PCM phase change materials. During operation, some of that thermal energy may be diverted to a storage system where it is maintained for...

Photovoltaic technologies ensure the security and diversity of the energy supply without any negative impact on the environment, playing an important role in the production of electricity. At the moment photovoltaic systems oriented to energy performance have a relatively low efficiency, in contrast to the types and technologies of PV, but also the context of their use. The performance in terms of efficiency and long-term electricity generation depends on the current voltage parameters that differ depending on the...

The ambient temperature inside a building is essential for occupant comfort, and it influences directly the interior microclimate. Keeping the inner temperature at an optimum value involves energy consumption for heating and cooling. Energy consumption can be reduced by integrating phase change materials into the structure of the building. In thermal regime, with the integration of phase change materials, an integration model based on a mathematical method suitable for a thermal process analysis is described. This...

The evaluation of the catalog parameters of the voltage, the current of a PV module is essential in the design and implementation of photovoltaic systems, the reference parameters differ depending on the temperature of the operating cells and the different levels of radiation. The analytical methodology was the basis for creating a characteristic model for modeling a cell or a photovoltaic module in Matlab/ Simulink, using cell data at STC, considering standard global radiation G = 1000 W/ m2, the operating temper...
