“…Building Integrated Solar Thermal (BIST) are emphasized and, where possible, compared to Building Added Systems (BAS), showing that BIST systems require more experimental and numerical investigations, especially in the case of active solar systems. [7,8]. V. Delisle et al, which makes a Cost-Benefit analysis of the integration of PV-T elements in building facades, defines Building Integrated Photovoltaic (BIPV) as multifunctional solar energy collectors that are components of the building envelope.…”

Abstract:In view of the recent preoccupation at worldwide level, for the integration of the solar systems components within the building skin, we made a numerical investigation in order to assess the opportunity to implement a long string of solar panels along a horizontal or vertical building surface.The study analyses deals with the phenomenon of self-shading, which appears in the case of medium and large solar systems that use solar panels placed one behind the other, along the same row (individual string), but also under the shape of parallel rows (parallel strings). The study creates a mathematical instrument for the evaluation of the shaded surface depending on the location of the panels and the relative position of the Sun. The shading-caused energy loss is analysed along the one-year period, for each of the 12 months, while the panels are considered either placed on a horizontal surface such as a building terrace, or on a vertical surface, such as a building facade. The simulations are made for six Romanian cities located in different climatic zones, characterized by different levels of solar radiation.

“…Christoph et al [1] have used several techniques using simple, more accurate models and fewer complexes than detailed physical models. In references [2][3][4], the applications of building integrated solar thermal collectors were presented and standards for assessing thermal performance of solar thermal systems were addressed. The major features, current status and existing difficulties related to the various types of solar thermal collectors were identified.…”

Abstract. The aim of this paper is devoted to an example of a concrete application in the bioclimatic architecture: integration of a simple solar air collector in building facades under Saharan climate. The originality of this work is to lift a serious problem that is often encountered in the summer when the indoor air cooling mode through natural ventilation becomes ineffective. We showed that the specific architectural integration of solar air collectors can bring a positive support to the thermo-aeraulic comfort by controlling the mass flow rate of the air entering to the heated building zone in cold season. The major inconvenience of this technique is often encountered in summer. To ensure the reliability of this technique that is sometimes regrettable, it is first necessary to control automatically the opening and closing the air ventilation valve.

This work presents the design, modeling, and implementation of a neural network inverse model controller for tracking the maximum power point of a photovoltaic (PV) module. A nonlinear autoregressive network with exogenous inputs (NARX) was implemented in a serial-parallel architecture. The PV module mathematical modeling was developed, a buck converter was designed to operate in the continuous conduction mode with a switching frequency of 20 KHz, and the dynamic neural controller was designed using the Neural Network Toolbox from Matlab/Simulink (MathWorks, Natick, MA, USA), and it was implemented on an open-hardware Arduino Mega board. To obtain the reference signals for the NARX and determine the 65 W PV module behavior, a system made of a 0.8 W PV cell, a temperature sensor, a voltage sensor and a static neural network, was used. To evaluate performance a comparison with the P&O traditional algorithm was done in terms of response time and oscillations around the operating point. Simulation results demonstrated the superiority of neural controller over the P&O. Implementation results showed that approximately the same power is obtained with both controllers, but the P&O controller presents oscillations between 7 W and 10 W, in contrast to the inverse controller, which had oscillations between 1 W and 2 W.
