Pros and cons of each orientation in houses

sun for the house

The orientation of a home refers to its position in relation to the sun. The direction the front of the house faces (north, south, east or west), as well as its location in the northern or southern hemisphere, will affect factors such as the amount of natural light it receives and potential energy savings. It is important to analyze all the pros and cons of each orientation in houses.

Therefore, in this article we are going to focus on analyzing all the pros and cons of each orientation in houses so you can choose the orientation of your home well.

Importance of alignment in a home

The solar exposure of a home, known as solar exposure, is a fundamental aspect of bioclimatic architecture. It involves analyzing the solar geometry and location of a building to determine the amount of light and natural radiation it will receive. This information is then used to inform the design and construction of the project.

Determining the ideal alignment for a residence is crucial both for energy efficiency, allowing for potential savings on lighting and air conditioning expenses, and for ensuring a high-quality, comfortable living environment.

It is essential to take into account the orientation of a house when making a decision about where to live, as this will greatly affect the amount of money spent annually in air conditioning, heating and electricity costs.

To accurately evaluate a property for mortgage, sale or inheritance distribution purposes, it is essential to determine its orientation and evaluate the resulting damages. The orientation of a house, Whether east or north, it can significantly affect its value, with prices varying by up to 20%.

How to calculate the orientation of the home

To determine the orientation of a house, it is essential to have a solid understanding of the movement of the sun in relation to the earth. The sun constantly rises in the east and sets in the west. Furthermore, it leans towards the south.

In the southern hemisphere, During winter, the sun's rays hit the Earth at a more oblique and horizontal angle due to the rotation of the planet on its axis. On the contrary, during the summer, the sun's rays hit the Earth at a more vertical angle.

Throughout the day, south-facing facades are bathed in the sun's rays, while east-facing facades are illuminated in the morning, west-facing facades in the afternoon, and north-facing facades remain without sunlight. direct.

By acquiring the plans of the house, we can determine the direction in which it is facing studying the movement of the sun in relation to the four main directions and the changes of seasons.

To accurately determine the alignment of a residence, the most reliable method is to review the architectural plans. In the event that these documents are not accessible, an alternative option would be to consult the Cadastre to obtain the necessary information.

By placing the top of the plans facing north, we can easily determine the cardinal orientation of each section of the house based on its location in relation to the up, down, left or right directions of the plane. To help with this process, use a compass.

By using a compass, one can determine the position of a house or piece of land in relation to the sun, as long as one has physical access to the property.

To determine the orientation of a house, simply go inside and face a wall. Take note of the direction the needle points. Another method involves using Google Maps or Google Earth to calculate the orientation of the house.

Google Maps is a convenient tool for determining the orientation of a property without the need for physical presence or reference to plans. Simply enter the address of the house to calculate its orientation using Google Maps.

After identifying the whereabouts of the residence, we enter the address into the search bar and adjust the orientation of the map to ensure that the top represents north. Later, we can draw conclusions simply by analyzing the location of each cardinal direction.

The best orientation for a house in the northern hemisphere

As one moves away from the equator, the winter season is characterized by shorter days and a southward shift in the solar path, resulting in sunrise from the southeast and sunset in the southwest. Consequently, North-facing areas do not receive direct sunlight.

During the spring and autumn seasons, the northern regions are lucky to experience the early and late arrival of sunlight, since the sun rises in the east and descends in the west.

During the summer season, the northern regions enjoy the warm embrace of sunlight in both the morning and afternoon.

Taking this into account, in a cold climate of the northern hemisphere the optimal direction for the orientation of a home would be towards the southwest, while in a warm climate it would be towards the northwest. As for the southern hemisphere, the ideal orientation of a house is yet to be determined.

Better orientation in a house in the southern hemisphere

As in the Northern Hemisphere, the Southern Hemisphere experiences an inversion in the distribution of sunlight: The north orientation receives the most sunlight and the south orientation receives the least.

During the winter season, the south orientation does not receive direct sunlight. However, as spring and autumn arrive, there is a gradual increase in the amount of sunlight it receives, even if it is during the first and last hours of the day. In summer, the south orientation allows you to capture the sun's rays both in the morning and in the afternoon.

In cold climates of the southern hemisphere, The optimal location for a house is the northwest, while in warm climates it is the southeast. Let's explore the benefits of each orientation in the northern hemisphere.

The uniformity of natural light is the main benefit of north orientation, making it an excellent option for facilities, offices and homes. In Spain, specifically in the southern region of Andalusia, the north orientation is considered the most advantageous for residential properties.

Using natural light throughout the year is the main benefit of a south-facing orientation. It is recommended to align key areas of the house, such as bedrooms and living room, in this direction. This orientation is particularly ideal for residences located in the northern regions of Spain, such as Asturias and Cantabria.

The situation in the East is quite complex. In northern hemisphere regions, placing structures facing east allows for optimal light exposure in the morning. This orientation is beneficial in extremely hot climates as it helps minimize direct exposure during peak heat hours of the day. On the contrary, the west orientation is advantageous in extremely cold climates, as it captures solar radiation during the last hours of the day, effectively maintaining heat inside the home.

I hope that with this information you can learn more about the pros and cons of each orientation in homes.
