Combining daylight with indoor comfort
For example, the floating frames of the VELFAC 200 product system allow natural light to enter the apartments while enhancing energy efficiency. On south- and west-facing buildings, solar glazing was used in the windows to let in the light but reflect the sun. This gives residents all the daylight they want while avoiding excessive heat.
In the apartments affected by road traffic and railway noise, Acoustic Ventilation windows from VELFAC ensure a comfortable indoor environ ment that combines both noise reduction and fresh air. Their two-part construction consists of an outer section with a lower openable sash supplied by VELFAC, and an inner section with an upper openable sash at the top of the window element supplied by KRONE. Together they create an opening area of 0.35 m2 in compliance with building require ments, while ensuring indoor noise levels do not exceed 46 dB, Lden.
VELFAC also supplied comprehensive data on all window solutions, which could be used to accurately calculate the building’s Life Cycle Assessment and provide documentation for the DGNB Gold certification.
