Nature serves as an example for dynamic shadings like Venetian blinds, roller shutters and awnings. A dynamic sun protection works like a broad-leafed tree that is providing shade in summer and loses its leaves in winter to let more light and warmth into the building - its function is oriented towards the daily and annual cycle of the sun.
The extended blinds function as solar reflectors during summer and prevent the heating and active cooling of buildings without considerable energy requirement. They give shade and provide for a glare-free daylight.
During the heating period the retracted slats, profiles and covers turn the windows into highly efficient solar collectors that provide precious heating of the room for free! This makes dynamic shadings an essential building block for low-energy and passive houses.
Dynamic sun protection suitably controls the energy and light incidence and, in a passive way, ensures high thermal and visual comfort all year round.
The development of sustainable buildings requires detailed knowledge, great accuracy in carrying out the work and professional quality controls of the builders, planners, advisers and professionals.
The Bundesverband Sonnenschutztechnik Österreich contributes to the section of shading, anti-glare protection and utilization of daylight by providing this detailed knowledge on an impartial level.
