What is the building?

The

envelope of the building includes all components that form a shell or skin of the building. These components separate the exterior of the building from the interior and are designed by a project architect or engineers to meet the needs of each individual application. The envelope building can also be defined as components that separate the conditioned areas from the unconditional space. The outer or unexpected living spaces are not included in the envelope, while any living space that is equipped with heat or air conditioning would be included. The building envelope must be carefully designed with regard to the climate, ventilation and energy consumption in the structure.

There are four basic functions of the building. These include the addition of structural support, humidity and humidity control, temperature control and air pressure control changes. These different functions also affect the envelope also by ventilation and use of energy in the building.

envelope consists of all external parts of the building, including walls, roofing, foundations, windows and doorand. Completed materials such as siding and decorative objects are usually not considered part of the envelope. Insulation, building paper and other components focused on control of moisture and air flow are usually included in the design of the building envelope.

Building envelopes are often characterized as "tight" or "free". The tight envelope is precisely designed to allow relatively few air leaks. This often requires significant amounts of insulation, seals, sealants and energy -efficient windows to form a tight shell for the building. Freely designed envelopes allow air from the outer to the interior. The free envelope can be created by a design or can be the result of poor construction techniques.

Many experts debate about the tight versus free building envelopes. The tight envelope allows a high level of control over the quality of internal air, energy consumption,Temperatures and humidity. This leads to a smaller number of moves and a more comfortable passenger environment and often leads to less waste in heating and cooling costs. Firmly designed envelopes also reduce the likelihood of molds or molds caused by moisture infiltration, which can prolong the life of building components. At the same time, stricter buildings also reduce how much natural ventilation can occur, leading to more extensive requirements for mechanical ventilation.

Freely designed building envelope makes it possible to transmit air transmission, which improves the quality of the inner air and often eliminates the need for mechanical ventilation. At the same time, these looser buildings tend to be more expensive and uncomfortable and can make the temperature level regulation. There is an increased chance of Moistures Mold and a higher amount of heated or chilled air are able to escape the leak in the envelope. This can increase energy accounts and negatively affect the environment by increasing greenhouse gases.
