The EWI Faculty on the campus of the TU Dellft is currently suffering from a low quality indoor climate. A sustainable and innovative redesign to reduce cooling load, introduce natural ventilation and enhance manual operating is necessary to please the users' needs and desires.
A high-rise building such as EWI endures large wind loads making it a challenge to design
a system that allows for natural ventilation. The existing glass facade results in exceeding
cooling loads. The redesign is developed as an integrated system to block sun radiation on
and break wind to off er the operating of windows at great heights.
By re-using the current load bearing structure and redesigning both layers of the doubleskin
facade, the users of EWI are off ered a quality indoor climate to be self-regulated. The
outer layer blocks sun and wind due to the aluminum perforated louvers with an open
area of 23 %, whilst the transparent inner layer with operable windows (the insolation on
line) is equipped with a KlimaVent unit allowing natural ventilation on all year per module.
