The apartment’s solar orientation interferes a lot in the resident’s daily life. Learn how to identify and which to choose.
Imagine yourself inside your dream house.
What is the climate, the temperature, what is the feeling you expect to have inside it?
This answer may vary according to your personal taste, but you certainly didn’t imagine yourself in a house too hot, too cold, humid or stuffy. A beautiful house is useless if it cannot provide you with pleasure and well-being.
Therefore, thermal comfort is a very important factor to be considered when choosing your apartment, and it is directly linked to the property’s relationship with the sun.
No wonder the sun is known as a source of life. In addition to comfort and well-being, the correct insolation guarantees a series of health benefits. Its presence inhibits the proliferation of fungi and bacteria that cause respiratory problems, in addition to being a source of vitamin D, responsible for the absorption of calcium in bones.
An efficient project must make intelligent use of the sun, so that the need for electricity and air conditioning consumption is reduced, making the construction more sustainable and economical. But that’s not the only way the sun can interfere with your pocket. According to data published by SECOVI (Civil Construction Union), the value of the plant can vary by up to 10% according to its orientation in relation to the sun.
Now that you know the importance of considering solar orientation when choosing your fit, we have prepared a checklist to help you with this analysis:
1. Visit the Place with a compass
Know in which direction the sun rises (east), and which direction it sets (west). The sun travels along this path slightly inclined to the north, especially in winter, which makes this orientation the most desirable, as it receives the sun for more hours of the day and guarantees more heat on cold days.
Facades facing east receive the morning sun and to the west, they receive the afternoon sun, which lasts longer and is much warmer.

The south face is the coldest as it receives less sun. Visiting the property at different times of day can also be a good strategy to identify these points.
2. Know what to prioritize
Rooms and bedrooms are considered long-stay rooms, so they should be prioritized.
The west face receives the direct incidence of the afternoon sun and can overheat the rooms in the summer, making it unpleasant to stay for long periods, so the east and north faces are the most suitable for these environments.
Some care must also be taken in the kitchen, bathrooms and laundry area. Despite being benefited by the presence of the sun, the direct incidence of sunlight can be harmful to appliances, it is important to observe if the openings (doors and windows) allow the correct ventilation of these environments.
3. Consider architectural features
The size of openings, windows, doors, room dimensions, balcony depth, eaves and other façade elements may or may not favor the entry of sunlight and ventilation. Each of these characteristics must be considered and analyzed.
The larger the openings, the more sun and more ventilation. The model of the frames is also an important detail to be observed.
Plants with integrated environments greatly favor natural lighting and ventilation. Cast elements such as cobogós are also a smart solution to separate environments without blocking light and wind.

In cases where there is intense sunlight, louvers, eaves and fixed elements on the façade can be used to block the sun’s rays and ensure greater thermal comfort to the environment.
4. Observe the surroundings
We call the distance between the building and the boundaries of the land a setback. In dense cities such as São Paulo, this is a very important factor that can affect the quality of insolation of properties.
Note the distance and height of neighboring buildings. The higher and closer they are, the more difficult it is for sunlight and ventilation.
The number of trees in the surroundings can also interfere with the thermal sensation of your house.
5. Other factors that interfere with the property’s thermal comfort
When added to good insolation, cross ventilation makes the environment even more pleasant. Larger openings favor circulation and, when arranged on opposite or adjacent sides, guarantee air quality and renewal.
Materials, colors and textures can be used in decoration to alleviate unfavorable situations of temperature and light. Light colors reflect light, illuminate and do not retain heat. The choice of coverings is also very valuable. Wood, granite, textiles and other materials can be used to balance the thermal sensation.
The sun is vital to our existence and that is why it has always been closely linked to our way of living and living. However, it is necessary to know how to use it to our advantage.
Here in the southern hemisphere, the north façade is the most pleasant and therefore the most valued, together with the east façade, they are the most suitable for long-term environments.
Architectural details can help to control insolation and favor ventilation, which should not be ignored when balancing thermal comfort.
Knowing the behavior of the sun allows you to make the most of it and observing it can be a great asset when choosing your next apartment.
