	In terms of the control function, the main purpose of the building envelope is to maintain a specific, comfortable internal climate despite changing conditions in the external environment. Its purpose is to make a building comfortable and livable~~, and thus ensuring the control function of a building is satisfactory is of the utmost importance~~.

	Controlling heat in a home is mainly done through the [[HVAC]] system ensure that air at a comfortable temperature is spread throughout the building. This requires the proper use and installation of [[furnace]]s and vents. Improvements to home energy efficiency can be made using natural heating through [[passive solar heating and cooling\|~~passive~~ solar heating]] ~~and the use of~~ [[~~trombe~~ wall]]s, [[~~solar~~ wall]]s, or [[solar chimney]]s ~~and through the selection of~~ proper [[insulation]] to prevent undesirable temperatures inside.<ref>Building Science Corporation.

	Controlling moisture is one of the most important functions that the building envelope serves, ~~due to the fact that~~ the harmful effects of [[water]] in building materials is extensive. Mold and rot are two ~~of the most~~ harmful effects of moisture intrusion in a house. Although in many instances the water by itself is not harmful - only ~~becoming an issue~~ when combined with other effects - it is vital to control water and moisture inside a building to prevent costly repairs and improve effectiveness of insulation efforts. For this reason, addressing the ~~control of~~ moisture in building enclosures generally takes precedence over other measures.<ref name="R3"/> Since water usually gets into the home through air currents, diffision, or heat transfer it is very simple to control moisture. Properly sealing cracks and paths that air can come in prevents moist air from entering the home. Choosing effective building materials for siding and insulation helps prevent rain or moist air from penetrating the home. As well, the use of vapor barries in walls prevents water coming in through diffusion. Finally, sloping of the ground away from the foundation and the proper use of weatherstripping and caulking in fenestration prevents excess water from entering the home.<ref>US Department of Energy.
