Operating for Efficiency

Relying on your building's HVAC system may guarantee the conditions in your building remain constant, but introducing high-performance operable windows can provide the same benefit -- and more. Newer models have made great advances that place them on par with other high-performance options. Ease of cleaning is another benefit, according to Ken Brenden, technical services manager for American Architectural Manufacturers Association. Certain operating window types permit cleaning of the exterior glass surface from the interior of the building. Advances in operable window technology will squash the fear you have about employees opening the windows while your HVAC system is trying to heat or cool the building. Operable windows can sometimes be installed more easily in retrofits than fixed windows.
