Is there a specific height restriction for furniture (such as in an open office area) that items should be under in order to allow the space to count towards credit compliance? In LEED 2009 it was 42". 

When evaluating regularly occupied spaces for Quality Views, permanent interior obstructions must be taken into account. Movable furniture and partitions may be excluded. However, according to GBCI, there is not a specific height restriction for furniture. This allows project teams flexibility when determining how quality views will be provided. To maximize views, consider using transparent partitions, and in open-plan offices, select low partitions or incorporate glazed panels.
