Passive solar also uses design principles and building materials to take advantage of the natural processes of radiation, conduction and convection of the sun’s energy to efficiently heat and cool buildings. Passive solar energy combined with natural ventilation can eliminate or reduce the need for mechanical cooling and heating during periods of the day. When considered at the design stages of building construction, passive solar is the most economical way to use solar energy. Knowledge of solar geometry, window technology, thermal mass and local climate is required to design passively heated (or cooled) structures. In northern latitudes, a few of the basic design principles are: The length of the building should be oriented on an east-west axis to maximize southern exposure;High-use, interior spaces requiring the most light and heat should be located along the south face of the building;Use of an open floor plan to facilitate passive system operation; andUse of shading devices to prevent heating during the summer is desirable.

Building orientation refers to the way a building is situated on a site and the positioning of windows, rooflines, and other features. A building oriented for solar design takes advantage of passive and active solar strategies. Passive solar strategies use energy from the sun to heat and illuminate buildings. Building orientation and building materials also facilitate temperature moderation and natural day lighting. Active solar systems use solar collectors and additional electricity to power pumps or fans to distribute the sun’s energy. Heat is absorbed and transferred to another location for immediate heating or for storage for use later. Passive solar heating makes use of the building components to collect, store, distribute, and control solar heat gains to reduce the demand for fossil fuel powered space heating. Passive solar heating strategies also provide opportunities for day lighting and views to the outdoors through well-positioned windows. The goal of passive design is to maximize solar gain while minimizing conductance. Passive cooling removes or rejects heat from the building, keeping temperatures cool. Avoiding any mechanical operations to moderate temperature achieves energy and cost savings by alleviating the cooling load demanded. Shading devices can also reduce unwanted solar gains by blocking the sun during the summer months, while natural ventilation, which relies on natural airflow and breezes, can reduce the need for mechanical cooling when the building is occupied (see Glare and Heat Gain Reduction strategy).
Renewable Energy Sources

PV and solar thermal energy are active solar technologies because they actively and directly use the sun’s energy to produce electricity. In contrast, passive solar technologies passively absorb heat from the sun’s rays and have no electronic components and no moving parts. Examples of passive solar technologies include solar collectors such as solar ovens, parabolic solar cookers, solar water heaters, and passive solar architecture (Kellogg and Pettigrew 2008). Passive solar technologies have all of the benefits of active solar technologies like PV panels (a renewable energy source, no pollution during operation, decentralized) but none of the drawbacks. They are technologically simple, easily constructed (often from recycled parts), and are nonpolluting throughout their life cycle, meaning that they represent a truly sustainable option for autonomous communities.
Solar research – a review and recommendations for the most important supplier of energy for the earth with solar systems
Published in International Journal of Ambient Energy, 2020
Every solar-energy technology features some combination of these characteristics to harness sunlight. Passive solar energy requires a building design that is intended to capture the sun’s heat and light. In passive solar design, heat and light are not converted to other forms of energy; they are simply collected. This is done through various design and building methods. The simplest conceptualisation of passive solar-energy design for the building is in a greenhouse, a design that allows solar light to pass into the interior and then captures the heat it generates inside to maintain year-round growing conditions. Passive solar features some of which have been used in the building. Passive solar is an elegant way to harness the sun’s energy, but it usually has to be designed into the original building plans to be made cost-effective. Once a building design has been finalised with siting, orientation, and structural elements, it is often prohibitively expensive to change or retrofit the facility to capture additional passive solar-energy benefits.

Solar energy is a type of energy that provides us big continual and cleanest sources of accessible energy. The existing solar energy on earth is about 4× MW and is 200 times greater than universal consumption. In the recent century, the universal utilization of solar energy in the form of sustainable energy is 2.1% that is 0.7% more than as calculated in 2001. In short, the consumption of solar energy and the usage of nanofluid technology has caught the attraction of many researchers [1]. It was firstly introduced by Dincer [2] using a photovoltaic system. Solar energy systems are devices that transform the sun's heat or light into a usable source of energy. This source can provide 1000 times extra energy as per the demand of the whole world. But unfortunately, the world is only 0.02% is utilizing. With the passage of time demand for solar energy is increasing day by day in developing countries [3]. The importance of solar energy is that transforms heat from sun and radiant light which is using a range of advanced technologies such as photovoltaic and solar heating. Interests and non-interests obtained from using solar power were considered by Ugli in 2019 [4]. He also emphasizes generating solar cells and batteries from the raw material. Some of the most common types of solar energy are systems including solar power plants, photovoltaic, solar water heating, and passive solar heating systems. Neelam [5] discussed the previous advancement in solar energy in (2019) and also studied different types like mono-crystalline, thin-film PV, polycrystalline, and perovskite solar cell. The degradation of organic contaminants within air and water streams, which can be regarded as the modified oxidation procedures, is one of the most important applications of this technology [6]. Bahnemann [7] briefly described the essential principles of photocatalysis, which focused specifically on the crucial mechanical and dynamic aspects along with some demands for effective photo catalysts. Kalogirous [8] focused on expanding the research in the solar energy field to enhance the systematic performance of the solar thermal collector and also explained that the use of solar energy is to heat the water to generate electricity.
