1,700 trees for a good climate

The Sagamihara Campus of the Aoyama Gakuin University near Tokyo comprises 20 buildings on an area of more than 160,000 m² and provides space for around 10,000 students and staff members. Energy-saving structures and carefully planned green spaces make it a veritable "Eco-Campus" - in comparison to a plan without such measures CO2 emissions were reduced by 23 percent. In the main buildings, horizontal and vertical louvers on one side and double-glazed windows on the other ensure that the annual energy consumption for heating and cooling is 40 percent below legal requirements. The louvers also provide an additional source of daylight, minimizing power consumption. The green spaces, designed using Vectorworks, with around 1,700 large Himalayan cedars and zelkovas make an important contribution to the good climate on the campus. Measurements of the campus-wide surface temperature with the help of the ThermoRender showed that the surface temperature in the tree-lined promenade, for example, is 10-15 percent lower than in other regions.
