There is a significant impact of classroom environments on the learning abilities of students. It has gained significant importance in the design and architecture professions. This study investigates the impact of green classrooms on the productivity and behavior of students. Twenty-two first-year students (between 19 – 22 years of age) from the landscape architecture department participated in this investigation. Participants' blood pressure and pulse rate were evaluated before and after rearranging and designing the studio (classroom) when the studio was changed into a green classroom. There was a significant improvement in the systolic pressure of students as they started studying in green classrooms (sig. = 0.017). These results suggested that there is a positive impact on the productivity and behavior of students working in green classrooms, which is an indication of the need to rethink the design layout of the classrooms and study spaces.
