The site is in an industrial production zone inside a large army base, in the Inner Shfelah Region, an area with cool winters, and hot summers with moderate humidity.
The army policy is not to provide any mechanical heating or cooling for work places in this area.
The challenge of this project was to create a working environment providing the maximum level of comfort without mechanical heating or cooling.
Computer assisted design studies showed that passive solar heating could easily achieve comfort conditions for most of the winter, while controlled daylighting which eliminates cooling load from artificial lighting, coupled with night ventilation cooling, could greatly increase summer comfort conditions.
These aims were translated into a series of south-facing roof clerestroy windows, providing winter passive solar direct gain heating, and high level of diffused daylighting to work surfaces through system of light diffusing baffles.
Summer night ventilation is assisted by fans mounted in clerestory windows, and internal air movement created during the summer working hours with ceiling fans when necessary.
