What is the building?
A building or envelope includes all components that separate the interior spaces inside the structure from the surrounding external areas. Shell can be composed of many different features, including walls, windows, doors, roofing, footers and foundations. While the building can consist of different materials, it will usually be made of some form of wood, stone, metal or concrete.
The building envelope helps to protect the interior in the building from external elements such as rain, wind and snow. It also acts as a barrier to prevent noise, insects and intruders. In addition to its role in protecting the interior of the building, the shell provides structural stability for the remaining components of the building. It also plays a major role in temperature control and at the same time allows passengers to regulate air pressure and humidity levels in the building. Finally, the building acts as a safety function to protect passengers and assets.
and Buishell Lding is often categorized as open or closed and these markings may have a great impact on the energy efficiencyktura. Older buildings will generally have an open shell, which means they are freely designed. This also means that the wind, moisture and pests can enter and get out of the building through cracks and other openings in the shell. Modern buildings are usually constructed more firm or closed. This means that it is harder for air, humidity and insects to enter space, making it easier to check the interior conditions.
both tight and free building shells require a careful balance between energy efficiency and air quality. Tight buildings leave less air leakage, which makes them cheaper to heat or cool. At the same time, fresh air has a heavier time to go through a tight shell, which often leads to poor quality of the inner air. Freely designed buildings allow multiplication to enter and escape, which means that fresh air always passes into space. At the same time, the conditioned air is capable of voltEnd, resulting in poor energy efficiency and higher service accounts.
In order to balance this problem, homeowners can take steps to tighten a free building or add mechanical ventilation to a tight building. If you want to tighten the building, add insulation, chirp or holes in the outer walls and add the weather around windows and doors. Home owners can also invest in energy efficient doors and windows that can significantly reduce thermal transmission through these surfaces. Simple ventilation systems consisting of fans and suction grids can help bring fresh air to a firmly designed building.
