Indoor air quality is improved when plants are placed in open areas, hallways, and in individual rooms. Transpiration from leaves increases air humidity, creating a more comfortable environment. If plants occupy 5% of a room volume, the relative humidity in winter can increase by as much as 20% and the room temperature by 1-3˚C. Room temperature decreases by 1-3˚C in the summer.
Some plants have the capacity to remove indoor air pollutants, either by capturing these onto leaf surfaces, or by absorbing and metabolizing pollutants. Different plants have specialized capacities to remove pollutants, and plant selection can target known problems and deliver a wide range of benefits when a diversity of plants occupy a space. Allow air to flow along as much green as possible indoors as it moves from room to room. Atriums, wintergardens, halls and plants in individual office spaces are all effective.
Studies show that sick leave from work is reduced by as much as 3.5 days per employee in offices with plants. The presence of green can improve the healing of patients in hospitals. Physical effects include a more regular heart rate and lower systolic blood pressure. Psychological effects come from the therapeutic impact of looking at plants. Green fosters neutral relaxed and happy feelings without negative feelings. Shops with green displays gain 12% in sales. Oriental style flower arrangements stimulate right brain functions while western style flower arrangements stimulate left brain functions.
Good healthy soil, potting techniques, water, and pruning are necessary to guarantee the continued vitality of indoor plants.
Create a more comfortable climate indoors with the use of indoor plants, which has a positive effect on the psychological and physical well-being of the users of the building.

In new development:
Design buildings with permanent places for green and plenty of natural light to guarantee that green is valued and maintained by the users.
In existing development:
Add indoor plants inside buildings in open areas, hallways and individual rooms to maximize the benefits for all users.
