To support the need for energy for a building either passively or actively, we can utilize solar energy wisely. By adopting a climate-sensitive approach, it is easy to reduce the use of energy for cooling, heating, or lighting purposes.  The passive solar design emphasizes natural energy flaws. Convection, conduction, and radiation are examples of energy flaws in building design. This uses conventional energy-effective devices with passive solar design elements like the thermal mass. Weather conditions are known to affect the rate of energy consumption and thermal comfort. The heat flow through building covering, air distributions, and radiation relations. determines the thermal environment of a building. Heat flow contributes to this more out of all other parameters. Therefore, we can judge the thermal behavior of a building by the total peak heat flows. 

What do different studies say about passive solar energy?

Different researchers have done different studies on the field of passive solar energy and its performance. One of the studies has shown that they also used computer simulations to design passive solar effectively. Moreover, they reported the use of photovoltaic models as covers for sunshades over windows. They used a method called the fine element method to study five different hollow brick walls that are lightly concreted. Here, they used the TRACE-700 simulation to compare three identical houses. Meanwhile, Liang and Mimari produced and panelized brick veneer, by estimating thermal resistance with a backup system of steel frames. They learned that an air cavity and a thin layer of cow fertilizer can help reduce flux through walls.

The roof was the most essential structural component in a hot climate through modeling and simulation of energy fluxes. A different study of numbers. They have conducted different research on a vented, low sloping lightweight, ventilated roof with no thermal insulation and a change in air temperature in the ventilated cavity. In addition, they have recorded several comparative thermal performance studies of various roof types have.

Many scientists have thus utilized theoretical, mathematical, and analytical methods of simulation to compare architectural elements such as sunshade, wall, and roof. This article contains theoretical and simulated research to evaluate the thermal efficiency of four rooms according to a varied sunshade type, wall, and roof combination. Each month, and on representative days throughout the year, they compared four rooms with each other in theory via a steady-state approach based on total heat charges.

They also compared the rooms with their performance each month on a normal day by utilizing the Autodesk Ecotect Analysis program. Moreover, they analyzed Individual and combined effects of specified passive components on the interior temperature in different experimental investigations.
