Solar Energy and Its Purpose in Net-Zero Energy Building

Abstract

The Net Zero Energy Building is generally described as an extremely energy-efficient building in which the residual electricity demand is provided by renewable energy. Solar power is also regarded to be the most readily available and usable form of renewable electricity produced at the building site. In contrast, energy conservation is viewed as an influential national for achieving a building’s net zero energy status. This chapter aims to show the value of the synergy between energy conservation and solar energy transfer to NZEBs at the global and regional levels. To achieve these goals, both energy demand building and the potential supply of solar energy in buildings have been forecasted in various regions, climatic conditions, and types of buildings. Building energy consumption was evaluated based on a bottom-up energy model developed by 3CSEP and data inputs from the Bottom-Up Energy Analysis System (BUENAS) model under two scenarios of differing degrees of energy efficiency intention. The study results indicate that the acquisition of sustainable energy consumption is critical for solar-powered net zero energy buildings in various building styles and environments. The chapter calls for the value of government measures that incorporate energy conservation and renewable energy.

Modeling the Performance of Amorphous Silicon in Different Typologies of Curved Building-integrated Photovoltaic Conditions

“…Research surveys have estimated that Tehran's sunny days and hours are about 313 days and 1742 hours a year, respectively. The increase from the southeast to the northwest of Iran is reduced, whereas it usually increases from the west to the east [22]. The irradiance map and statistical irradiance simulations show that irradiance level in clear air is theoretically high in Iran, including Yazd, Kerman, Tabas, Birjand, Iranshahr, Chabahar, Shiraz, Bam, Bushehr, and desert areas.…”

Floating Solar Power Plants: A Way to Improve Environmental and Operational Flexibility

“…Net present value (NPV) is the difference between the present value of cash inflows and the present value of cash outflows over a period of time Net cash flow (NCF) is a metric that tells you whether or not greater cash got Figure 2. A floating solar power plant's components [9] here in or went out of a commercial enterprise inside a selected duration of time [44]. This balance is compared to interest rates as a predetermined criterion for project management.…”

“…High-potential photovoltaic technology has the potential to contribute to 5% of Europe's power needs by 2030 and 11% by 2050 [8]. However, just 1% of total electrical power required by humans, or 18,400 terawatts, is supplied by various solarto-electricity conversion systems [9].…”

Thermal Performance and Heat Dynamics Energy and Exergy of Integrated Asphalt Collector Storage: Sources of Thermal Energy, and Thermoelectric Energy

“…Concrete-based collectors the design and integration of SWH into building components such as the roof and walls have been finished. On an inclined roof, Esmaeili Shayan et al [10] studied and tested a concrete solar water heater (CSWH) for home hot water [8,9]. A researcher installed a solar concrete collector on a flat roof to restrict a home's heat absorption while still supplying domestic hot water [10].…”

A researcher installed a solar concrete collector on a flat roof to restrict a home's heat absorption while still supplying domestic hot water [10]. The parametric analysis and experimental and numerical research of a CSWH as integrated on the wall and/or facade were reported by Azadbakht et al [11].…”
