- Advantages: reduced glare, improved daylight penetration, less reliance on artificial lighting, react differently according to the sun’s orientation and to adapt to varying external conditions, reduced solar gain (need for air conditioning).
- Dis-advantages: susceptible to external factors (high temperatures, wind, sand, salt water), fatigue, maintenance (in particular referred to a high number of mechanical parts), achievement of same life time.
