WINDTECH Consultants is a company of consulting engineers specializing in the analysis of wind effects on buildings, structures and the environment. Since 1991, the company has been providing wind engineering and related high technology services for over 2,000 major building projects, assisting planners and building design professionals.

The trend to building taller, larger and lighter structures has highlighted the need for specialist services in providing accurate analyses of the effect of winds. This generally results in significant savings in the cost of the facade and the structure in comparison with the use of estimates from wind loading standards.

Analysis techniques developed by WINDTECH Consultants over the past few years place the company at the forefront of its field in the analysis of the effect of wind on the most complex structures.
