Functionally, LiveWall can be placed as high as your building infrastructure, plumbing, and ability to access it for maintenance will allow. But, as with any siding, high wind can pose a threat to the security of an outdoor living wall siding. The LiveWall System provides excellent wind stability when properly installed. To do this, a review of wind pressure and associated variables, such as the building’s geographic location, surrounding terrain, shape, slope, height, openings, and other features is essential.
For starters, one must consider the typical high wind speeds for the installation site. Consult your region’s ASCE 7.95 Figure 6-1 Basic Wind Speed, or FM Approval Standard for Class 1 Exterior Wall Systems. In addition, the structural engineer must consider the natural forces on the building site; for example, is the building situated along water, mountains, or in an open field, and do tall trees or taller buildings surround it? Each of these factors can create a channeling force to intensify wind pressure against a structure.
Of course the building design itself is very important. Low rise buildings, generally regarded as 60 feet or lower, are less affected by a given wind load than buildings that are 60 feet and taller, which may experience substantial uplift forces in addition to direct/positive wind pressure.
Wind accelerates as it passes over a wall, causing a pressure differential and uplift, that is exerted on any living wall design. Redirected winds of this nature tend to whirl and swirl, and such forces are typically greatest at the edges of the wall but vary with building shape and height, overall exposure, size of openings, and other local factors.
