It was used in design of a plus-energy detached single-family house with usable area 98 m2. meets requirements latest building regulations Poland. The building, HVAC installation, subjected to energy analysis, and numerical model also developed. tested based on TMY data for location Wroclaw, Analy...

In this paper, we present a simple method for preparation of graphene-ZnO nanocomposites (G-ZnO). The method is based on thermal treatment of the graphene oxide (GO)/ZnO paste which reduces the graphene oxide into the graphene and leads to the formation of the G-ZnO nanocomposite. The structure, morphology and optical properties of synthesized nanocomposites are characterized with XRD, FESEM, F...

The 2018 revision of the European Performance Building Directive (EPBD) requires that from year 2020 onwards, all new buildings will have to be “nearly zero energy buildings”. It also further promotes smart building technologies, raising awareness amongst owners and occupants value behind automation. Commission identified, in 2011, Key Enabling Technologies (KETs), which provide basis for innov...

A building integrated holographic concentrating photovoltaic-thermal system has been optically and energetically simulated. The system has been designed to be superimposed into a solar shading louvre; in this way the concentrating unit takes profit of the solar altitude tracking, which the shading blinds already have, to increase system performance. A dynamic energy simulation has been conducte...

The concept of a building thermal battery refers to storing the supplied heat and releasing it another time through radiation convection. introduction performance has created more convenient solution problems load estimation, control optimization, building-grid integration, etc. Some literatures have expanded original definition batteries, including PV RE (photovoltaic renewable energy), HVAC o...

Adaptive control of solar heat gain and visible light transmission through windows is perceived to be a potential measure for enhancing energy conservation visual comfort in buildings. In this study, novel versatile window, named Building Integrated Photovoltaic (BIPV) smart was proposed offer simultaneous improvement daylighting control, on-site electricity generation building efficiency, comp...

Hybrid photovoltaic thermal (PV/T) solar system comprises a solar collector which is disposed on photovoltaic solar cells. The disadvantage of a conventional photovoltaic cell is that its performance decreases as the temperature increases. Indeed, part of the solar radiation is converted into electricity and is dissipated as heat, increasing the temperature of the photovoltaic cell with respect...

Room-temperature photocurrent measurements in two-dimensional (2D) inorganic-organic perovskite devices reveal that excitons strongly contribute to the photocurrents despite possessing binding energies over 10 times larger than the thermal energies. The p-type (C6H9C2H4NH3)2PbI4 liberates photocarriers at metallic Schottky aluminum contacts, but incorporating electron- and hole-transport layers...
