A Passive solar system collects heat as the sun shines through the windows and is stored on thermal mass. It uses the sun’s energy for heating or cooling buildings. Future homes should be constructed with this system because its advantages outweigh its drawbacks with low emissions of CO2 or other pollutant, consists of little maintenance, and has positive long term effects such as low electric bills.
This system releases low emissions of CO2 or any other pollutant because it takes advantage of a structure’s climate, site, and materials to minimize energy use. Solar passive design integrate a combination of building features to reduce or even eliminate the need for mechanical cooling, heating or daytime artificial lighting. Windows that collect solar energy are faced within 30 degrees of the south and should be shaded during summer to avoid overheating. However, during the winter the windows cannot be shaded as said in the online article (Passive Solar Home Design). Heat is stored on thermal mass, typically bricks, tiles, stones, masonry, or water; this prevents rapid temperature shifts, and absorbs heat from sunlight in the winter and from warm air in the house during the summer. The heat flow is natural and does not require the use of mechanical equipment. Heat is transferred to different areas of the house through conduction, which occurs when heat moves between two objects that are in direct contact with each other. Also, convection, which is transferred through a fluid; this can be air or water. As well as thermal radiation, this is a process by which energy is emitted by a heated surface and travels to its point of absorption ; this is explained in the online article (Passive solar design). By protecting t...

Solar energy is energy taken from the light that reaches earth's surface from the sun. There are four different kinds of solar energy, which are active solar systems, passive solar systems, photovoltaic cells and concentrating power systems. An active solar systems is a system that captures solar energy by mechanical means. Common active solar systems are often in buildings or homes. Some examples are roof collectors and water heating. Low Intensity and high variability have limited the use of active solar energy in Canada. A pass...

In passive solar design, the vertical and horizontal surfaces control the heat transfer; in winters collect and distribute solar heat and dissipate heat in summer. Passive solar techniques utilize solar energy through direct or indirect solar gain to achieve environmental comfort in the building. The key factors in passive solar building design are: site planning and design; thermal mass; solar geometry; ventilation and vegetation.
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
The prime advantage of this approach to harnessing solar energy is that the process is simplified by combining energy gathering and storage into a single step. This process is robust, stable and cheap. One limitation of this process is, while this is useful for heating applications, production of electricity would require another step using thermoelectric devices or producing steam to run a generator.

Instead of big ugly solar panels we will use discreet solar roof tiles to help save energy. Trees will be planted around the border of each property to provide privacy and reduce sound. Each house will have a cellar or a ground fridge that chills
In the Valley of the Sun, where cloudy days are few and far between, one would think rooftop solar is a great way to reduce or eliminate your utility bill. This paper will focus on three aspects of deploying rooftop solar: cost, efficiency, and permitting. For those thinking of pulling the trigger on this popular energy saving option please read on.
As a group we hoped to make a design that would be more efficient through reducing the cost, improving the storage, and increasing the efficiency of converting the solar energy into electricity. Design 1 increased the efficiency by combining two of the technologies that currently exist. It uses the solar panels to absorb the solar energy which will convert it into electricity and the rest of the heat that are not converted will flow
Sunspaces or Sunrooms which are similar to solar greenhouses work with the elements of direct gain and indirect gain system features. Sunlight entering the sunroom is kept in the thermal mass and air of the room. Sunlight is brought into the house by way of conduction through a shared mass wall in the rear of the sunroom, or by strategically placed vents that permit the air between the sunroom and living space to be exchanged by convection. The sunspaces is designed to heat tjacent living spache sunspaces as well as the adjac
Passive Solar Design- to provide a free heating and cooling system by exposing the south facing façade to direct sunlight during the winter months, only allowing the interior of the building to absorb the sunlight while shading the summer sun and not allowing it into the building to keep it cooler inside.
SWHSs are splitted into two categories which are active and passive. Passive system is one of the oldest systems for utilization of solar energy. Mainly, it is used to be heated and cooled of the building. It uses density gradients (gravitational forces) to provide with natural cycle the transfer of water or heat transfer fluid while active system uses a mechanical system (circulating pump) for cycle of water or heat transfer fluid [24].
Solar collectors are special type of heat exchangers that transform solar radiation energy into thermal energy. The key component of all solar system is the solar collector. This is a device which absorbs the solar radiation from sun converts into heat and transfers this heat to a fluid ( air, water, oil ) passes through the collector. The solar energy collected is carried from the circulating fluid either directly to the hot water or to a thermal energy storage tank from which can be utilized for use at night or cloudy days.

Solar water heaters work by using energy from the sun. There are two types of systems for solar water heaters, an open system and a closed system (“Tapping into the Sun”). These systems depend on the type of climates they are installed in (“Tapping into the Sun”). Open systems are worth the installation if the weather is year round sunny, closed systems are better if the weather gets cold. The water cannot be run during winter so the system will be switched to fuel and in the summertime when it is warm, so the sy...
