Carrying out daily tasks in a very hot house becomes very difficult in the summer, and even into the night, good hours of sleep become uncomfortable on hot and humid nights, while investing in easy ways and measures to reduce the temperature in the home and creates a feeling of comfort and refreshment throughout the day And keeps cool into the night hours.
We start with the easiest and most efficient way to naturally ventilate spaces in the summer, without the need for any tools, thus saving the additional costs. The method is to open a window on the side from which the air enters the house, and then simply open the doors or windows opposite them on the other side of the same space, to create a flowing air stream that fills the room sweeping, so that the air entering the first window draws out the old warm air, and pushes it out through the corresponding window. There are types of windows that are more efficient than others when trying to ventilate the room in this way. Top-hung windows that open outwards or windows that open with a pull-up are ideal for implementing this option. When the lower part of the window is opened on the side of the house, cold air enters from it and warm air rises to above. , then any hot air that collects at the top of the room will be forced out the top half of the opposite window.

The effectiveness of this advice is also enhanced by the use of thermal curtains that help to regulate the temperature in the house, and they act as a window covering that reflects the sun’s rays and directs them away, as well as external shade is a natural and effective solution, such as the presence of a roof or sun breakers, and even the presence of some types of trees outside The house can help block the rays in the summer and let them in in the winter when the leaves fall, and on the on the other hand, in rooms exposed to the most sun in the afternoon, drawing regular blinds will block the sun and keep the room cool at night.
Unlike electric fans that send air through a room, air conditioners lower the temperature in a room by drawing in warm air and passing it through a compressor or compressor, through a drain pipe in a window or wall to the to let hot air out, and then to blow cooler air. To ensure the maximum benefit and effect, it is necessary to choose a suitable size for the space to be cooled, since the capacity of portable air conditioners is estimated in British thermal units “BTU”, the higher its value, the larger is the area it can cool, for example, the air conditioner with the capacity of “BTU 9000” will work in a Room of about two and a quarter meters in size. Alternatively, a ceiling fan can be installed. Ceiling fan designs have come a long way since the 1970s. There are now some stylish and appropriate modern models that can create a feeling of comfort in hot weather, they do not effectively reduce the room temperature as much as they create a pleasant breeze. The best advice here is to install the fan to rotate in the opposite direction, ie counter-clockwise for better results, as it will push the air directly downwards instead of pushing it across the room, giving a concentrated air flow.
Lights and electrical appliances
Most of the electrical appliances generate a certain amount of heat when they are turned on, such as ovens, computers, televisions, phone chargers, etc., so turning them off will help keep some coolness in the room and prevent that more heat is generated from, so it is preferable to operate them in the early morning hours in summer. Lights are also a special source of heat, related to the idea of warming the space both psychologically and practically, and bedside lamps add to the heat discomfort while trying to sleep. The type of lamp has an effect on the amount of heat emitted by the lighting fixtures around us. Conventional light bulbs generate light that is partially efficient, emitting up to 90 percent of its energy as waste heat, while LED lamps emit less heat and save money of lighting fixtures.
It is certain that the correct insulation of the house can greatly contribute to solving this problem, since it is observed that on hot days the temperatures rise on the upper floors, due to the accumulation of hot air at the top, and the upper rooms often get warmer than those on the lower floors, and the reason is that when the sun shines on the roof of the house (especially if the roofing material is dark in color), heat is absorbed and transferred to the attic space without proper insulation of the loft. This heat will still radiate into the upper floor rooms, and this can be avoided by knowing how to properly insulate the ceiling and upper floor.
Glass space solutions
Increasing the glass areas in windows and doors has become an effective way to improve the amount of natural light entering the house and to improve the connection with the garden and the landscape. But with the desire to let in as much light as possible, the greater the chance of overheating, and you may have felt the so-called “greenhouse effect” on sunny days, either in a kitchen with large expansive sliding glass doors or in a living room with several large windows overlooking the garden. Here comes the role of awnings, which are one of the best ideas to cover and shade the windows or doors of the outdoor patio from the glare of the sun, thus helping to keep the house cool inside as the awning works to to create a coolness. shadow patch directly in front of any doors and windows, protecting it from the glare of the sun. Being retractable, it offers a flexible option as it can be completely retracted and folded when not needed. There are many options, whether open or fitted with a cassette, and the use of solar control film, which comes in the form of a transparent adhesive that sticks to the window glass on the inside or outside, can be an ideal solution be in the case of large areas of glass or glass ceilings, especially those oriented south. A cheap and easy way to ensure the room doesn’t overheat while still enjoying outside views, so interior spaces can stay bright and cool at the same time.
In the Mediterranean regions, blinds or shutters are often used on windows, as the shutters here serve a dual purpose. They keep the sun out of the house and at the same time allow cross ventilation, using what is known as night disinfection, where the windows are left open all night while the shutters are closed, but the presence of ventilation holes in them will allow air. to pass inside the house, extracting a large amount of heat stored within the walls.
Ultimately, these methods will somehow contribute to partially mitigate the heat, but the best way to avoid overheating of buildings is to intelligently establish, study and plan buildings at the design stage based on consideration of how the house receives air, sun and various temperatures, through an approach that takes heat changes into account throughout the year. This means careful selection of the designs, components, materials and elements that make up the material of the building, to achieve maximum performance, whether in new construction, when the house is being extended or even when the house is being renovated and improved.
