The autonomous energetic system is for a residential building and it has as primary sources exclusively renewable resources (biomass and solar energy). For obtaining electrical energy, photovoltaic sources and a Stirling engine are used. They operate simultaneously in 1:3 ratio – electrical/thermal energy. Solar collectors and a pellet boiler are used to cover the necessary of thermal energy. T...

This study aims to identify the factors influencing promotion of Building-Integrated Photovoltaics (BIPV) using FGI and 1st Delphi methods omit, add, group affecting BIPV, applying a 2nd method confirm relationships between identified factors. A survey companies engaged in BIPV industry was conducted collect data, statistical analysis, such as exploratory factor analysis correlation data collec...

The integration of photovoltaic (PV) generators in the envelope of a building by means of building-integrated photovoltaics (BIPV) offers an immense potential, both in market development and the production of renewable electric energy that is close to the point of electricity consumption. In Germany, for example, by integrating photovoltaics in buildings up to 50% of the electricity demand can ...

Building Integrated Concentrating Photovoltaic (BICPV) window represents a promising alternative approach for improving the electricity generation of photovoltaic cells when integrated into building windows. As new concept, BICPV smart consisting an optically switchable thermotropic layer with PV offers potential to simultaneously generate and control solar heat visible light buildings. In this...

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 photovoltaic module building integration level affects the temperature and, consequently, its output power. In this work, a methodology has been proposed to estimate influence of architectural on energy balance with natural ventilation or forced cooling systems. developed is applied for five technologies (m-Si, p-Si, a-Si, CdTe, and CIGS) four characteristic locations (Athens, Davos, Stockh...

Planning energy-efficient buildings which produce on-site renewable energy in an urban context is a challenge for all involved actors in the planning process. The primary objective of this study was to develop a façade assessment and design tool for solar energy (FASSADES) providing the necessary information for all stakeholders in the design process. The secondary objective was to demonstrate ...
