Passive solar designs seek to optimize the comfort of your home using solar energy. This means taking advantage of the power of the sun to heat your home in the winter and prevents excessive heating in the summer.
Three basic principles of thermodynamics rule how heat transfer occurs in the assisted environment: convection, conduction, and thermal radiation. The passive solar design combines the underlying concepts with local conditions to optimize heat gain (heating) and heat loss (cooling). You can find optimum solar design services from various web sources.
The main thermodynamic concept
Heat transfer occurs in three fundamental ways: conduction, convection, and thermal radiation.
– Conduction is a heat transfer between the materials due to temperature differences – so when gas, liquid, or solid touch something hot, heat is transferred from the hot thing until the temperature equalizer.
– Convection is a heat transfer that only occurs in gas and liquid due to diffusion or current. In the context of passive solar design, convection refers to how air moves both in the house and between houses and the outside.
– Thermal radiation is electromagnetic radiation emitted by all agencies in heat form. Solar radiation occurs mainly through windows and roofs of buildings and is responsible for most solar heat rises.
Understanding and utilizing the peculiarities of building sites is the middle of the effective passive solar design.
Climate: Detailed local climate data plays a key role in passive solar design. Day’s degree heaters and day-to-day coolers are the main metrics that help passive designers model the requirements of heating and cooling based on local climate data.
Surya Line: The trajectory that the sun follows in the sky every day varies throughout the year due to the slope of the axis in connection with its orbit around the sun.
General design element
One of the overall design goals for passive solar homes in the climate-driven by North American heater is to allow sunlight in the winter and keep it during the summer. The window facing south which has sun exposure during the day during the winter is the key.
