"Ones facing west get the sun's heat for a longer length of time than homes facing east." These are hot during the most of the day. "When compared to other directions, doors and windows facing west become damaged faster owing to heat," says Lakshmi Chauhan, an Indore-based Vastu consultant. The amount of sunlight that reaches each square foot of floor space is important when choosing where to locate a home or building. Areas exposed to direct sunlight for a large part of the day are very warm during those times, while places with less direct exposure to the sun are usually cooler at midday.
West-facing houses have several disadvantages. They tend to be hotter than others - by as much as 10 degrees Celsius (18 degrees Fahrenheit) - and they require more air-conditioning. Windows must be kept closed, since open windows will cause excessive heating in summer and cold temperatures in winter.
The sun's heat affects everything on the western side of the house - floors, walls, and furniture - more than it does the other three sides. To protect your belongings, keep plastic or aluminum sheeting over window wells and other areas where items can be placed. This will prevent heat from reaching them through the glass.
In addition to being hot, west-facing houses are also vulnerable to wind damage. Storms coming from the west carry rain and snow along with them which can blow into homes through open windows and doors.
1. North-south facing homes: A north-south facing home not only avoids direct sunlight during the day, but it also benefits from the current of the wind. These two variables work together to keep north-south facing units cool and ventilated all year. The primary advantage of a north-south orientation is that it allows for more natural light into the house.
2. South-north facing homes: Much like a north-south facing home, a south-north facing unit gets beneficial winds and cooler temperatures without being exposed to the sun's heat during the day. This is because southerly winds rise as they approach the ground, so these homes get cooled off even in the summer months.
3. West-east facing homes: Homes with western exposures tend to be warmer in the summer than those with eastern exposures because there is less shade and more sunlight reaching the west side of the house. Western homes tend to be cooler in the winter because cold air is drawn under low-lying roofs and into walls where it cannot escape.
4. East-west facing homes: Like west-east facing homes, east-west facing units tend to be hotter in the summer and colder in the winter. However, unlike western exposures, eastern exposures do not receive any benefit from solar exposure in the summer or winter.
A south-facing residence often receives the majority of the day's sunlight, particularly at the front of the house, and is thus brighter and warmer. A north-facing residence receives sunlight from the rear of the house and is usually darker and naturally colder than a south-facing one. However, modern construction techniques can reduce these differences significantly. The amount of sunlight a residence receives depends on where it is located in relation to the sun. If it is east or west of the solar meridian (the path that the sun takes throughout the year), then it will face either north or south.
In general, a residence will face in the direction of the prevailing wind if it is not protected by walls or a hedge. This is because trees tend to grow toward the ground, so they would face into the wind if they were not prevented from doing so by an obstacle such as a wall or hedge. However, if the land on which the tree stands is flat or slightly sloped, then it would be advisable for the owner to provide some protection against the wind. This could be done by building a shelter for the tree or planting it next to a wall or fence.
Trees protect homes from extreme temperatures. In cold climates, they keep heat in during cold months and take advantage of warm days to bake into bricks and other building materials.
