An office per developer would be a dream, unfortunately the m2 prices are quite high in our area, thus we are forced to have some sort of open space, we are creating zones with 4 desks each group is separated from the others with furniture and green plants on top of the furniture. In general we are software developers so the office env. is typically quite, except for keyboards, those are on-fire :D.
For lights, since it is one of the most important aspects, we are leaning towards zumtrobel light fields 3, which is supposed to be one of the best lightening options, white lights for work areas and warm lights in relax zones.
Thanks for the airflow suggestions, we will take them in consideration.
